OPINION OF THE BOARD (by G.T. Girard):
SUMMARY OF TODAY’S ACTION
This identical-in-substance rulemaking consists of two separate consolidated dockets.
The rulemaking updates the Illinois hazardous waste regulations to incorporate revisions to the
federal regulations. The United States Environmental Protection Agency (USEPA) adopted the
federal hazardous waste amendments that prompted this action during two consecutive time
periods. Those were the periods of January 1, 2006 through June 30, 2006 and July 1, 2006
through December 31, 2006. This proceeding adopts amendments to 35 Ill. Adm. Code 703, 720
through 728, and 739. Also included in this proceeding are amendments to complete Board
action based on USEPA amendments of March 5, 2005 and to correct that of September 8, 2005.
These amendments also make a series of substantive and non-substantive corrections and
stylistic revisions to segments of the text that are not otherwise affected by the covered federal
amendments.
This opinion and the related order adopt identical-in-substance amendments in the
hazardous waste program area that the Board proposed for public comment on March 20, 2008
See
32 Ill. Reg. 4915 (Part 703), 4970 (Part 720), 5030 (Part 721), 5174 (Part 722), 5216 (Part
723), 5228 (Part 724), 5429 (Part 725), 5605 (Part 726), 5685 (Part 727), 5697 (Part 728), and
5904 (Part 739) (April 11, 2008). The rules adopted today are largely unchanged from those
proposed on March 20, 2008.
Sections 7.2 and 22.4(a) of the Environmental Protection Act (Act) (415 ILCS 5/7.2 and
22.4(a) (2006)) require the Board to adopt regulations that are “identical in substance” to
hazardous waste regulations adopted by the USEPA. These USEPA rules implement Subtitle C
of the federal Resource Conservation and Recovery Act of 1976 (RCRA Subtitle C) (42 U.S.C.
§§ 6921
et seq
. (2005)). The federal RCRA Subtitle C hazardous waste management regulations
are found at 40 C.F.R. 260 through 268, 270 through 273, and 279.

2
Section 22.4(a) also provides that Title VII of the Act and Section 5 of the Administrative
Procedure Act (5 ILCS 100/5-35 and 5-40 (2006)) do not apply to the Board’s adoption of
identical-in-substance regulations.
This opinion supports an approximately 830-page order that the Board also adopts today.
The Board received one substantive three-page public comment on the proposed amendments,
those submitted by the Illinois Environmental Protection Agency (Agency). The Agency
comments generally supported the Board’s proposal, and they responded to questions that the
Board included in the March 20, 2008 proposal concerning options for Board action and the
Board’s stated preferences relative to a handful of difficult amendments. The Board has also
responded to communications and suggestions from the Joint Committee on Administrative
Rules (JCAR).
The Board will file the amendments with the Office of the Secretary of State no less than
30 days from the date of this opinion and the accompanying order. That filing will cause the
amendments to become effective, and it will result in their publication in the
Illinois Register
.
The purpose of the delayed filing is specifically to allow USEPA an opportunity to review and
comment on the amendments before they become effective.
As a special note, the Board particularly requests that USEPA comment on the Board’s
adopted amendments relating to certain of the July 14, 2006 corrections to the hazardous waste
and used oil rules. The Board has declined to follow certain USEPA corrections, believing them
to be in error. The issues raised by those segments of the corrections and the Board departures
from the federal text are discussed at pages 29 through 57 of this opinion.
FEDERAL ACTIONS CONSIDERED IN THIS RULEMAKING
The following listing briefly summarizes the federal actions considered in this
consolidated RCRA Subtitle C update rulemaking:
Docket R07-5: January 1, 2006 through June 30, 2006 Amendments
USEPA amended the federal hazardous waste regulations once during the period January
1, 2006 through June 30, 2006, as is summarized below:
71 Fed. Reg. 16862 (April 4, 2006)
USEPA amended various provisions of the hazardous waste regulations to reduce the
paperwork burden imposed by the rules. Some of the reduced requirements apply only to
members of USEPA’s Environmental Performance Track Program. The affected rules
include hazardous waste management facility standards and aspects of the permitting
requirements and land disposal restrictions.
Docket R07-14: July 1, 2006 through December 31, 2006 Amendments
USEPA amended the federal RCRA Subtitle D regulations twice during the period July
1, 2006 through December 31, 2006, as are summarized below:

 
3
71 Fed. Reg. 40254 (July 14, 2006)
USEPA adopted a number of corrections to various of the hazardous waste and used oil
management regulations.
71 Fed. Reg. 42928 (July 28, 2006)
USEPA amended the definition of hazardous waste to exclude cathode ray tubes (CRTs)
that are managed within specified conditions. USEPA intends to encourage the reuse and
recycling of used CRTs and glass from CRTs.
Completion of Board Adoption of March 5, 2005 Federal Amendments
Additional action is required to complete Board adoption of the March 5, 2005 (70 Fed.
Reg. 10776) USEPA amendments to the manifest system. The Board incorporated the changes
made by USEPA into the Illinois regulations in the consolidated docket, UIC Corrections,
USEPA Amendments (January 1, 2005 through June 30, 2005, R06-5, RCRA Subtitle D Update,
USEPA Amendments (January 1, 2005 through June 30, 2005), R06-6, RCRA Subtitle C Update
(January 1, 2005 through June 30, 2005), R06-7 (Jan. 5, 2006) (consolidated). Because USEPA
had codified a newer version of various provisions that would not go into effect until September
5, 2006, the Board found it necessary to depart from the structure of the corresponding federal
regulations and defer removal of lapsing text until after the September 5, 2006 effective date of
the federal amendments. This is the first docket after September 5, 2006 in which the Board may
complete the amendments begun in consolidated docket R06-5/R05-6/R05-7. A table appeared
in the Board’s January 6, 2006 opinion in consolidated docket R06-5/R06-6/R06-7 outlining the
additional amendments necessary to complete work on the March 5, 2005 federal manifest
system amendments. The Board repeats that table below as Table 1, which begins on page 63 of
this opinion.
Correction of Amendments Based on the September 8, 2005
Federal Standardized Permit Rule
On September 8, 2005 (70 Fed. Reg. 53420), USEPA adopted new Standardized Permit
Rule for hazardous waste treatment and storage facilities in a new 40 C.F.R. 267. The Board
adopted the corresponding provisions in the Illinois rules in a new 35 Ill. Adm. Code 727 in the
consolidated update docket, UIC Update, USEPA Amendments (January 1, 2005 through June
30, 2005, R06-16, RCRA Subtitle D Update, USEPA Amendments (January 1, 2005 through
June 30, 2005), R06-17, RCRA Subtitle C Update (January 1, 2005 through June 30, 2005 and
March 23, 2006), R06-18 (Nov. 16, 2006) (consolidated).
On April 5, 2007, the Agency submitted a letter to Board staff relating corrections that
the Agency perceived as necessary in Part 727. The letter raised seven areas of concern over the
Illinois version of the Standardized Permit Rule. The Board entered the letter into the
consolidated docket R06-16/R06-17/R06-18 as PC 3 and into the present consolidated R07-
5/R07-14 docket as PC 1, to give consideration to the issues that the letter raises. The Agency’s
concerns and the Board’s responses are set forth beginning on page 7 of this opinion.

4
No Later RCRA Subtitle C (Hazardous Waste) Amendments
of Interest
The Board engages in ongoing monitoring of federal actions. As of the date of this
opinion and accompanying order, the Board has identified no USEPA actions since
December 31, 2006, that further affect the RCRA Subtitle C hazardous waste rules in a way that
requires immediate Board attention.
When the Board observes an action outside the nominal timeframe of a docket that
requires expedited consideration, the Board will expedite consideration of those amendments in
the pending docket. Federal actions that could warrant expedited consideration include those
that directly affect the amendments involved in this docket, those for which compelling reasons
would warrant consideration as soon as possible, and those for which the Board has received a
request for expedited consideration.
In the present instance, the Board has not identified any federal actions that fulfill these
criteria prior to this final action on the present amendments. Thus, the Board has not added
amendments to those proposed on March 20, 2008.
Summary Listing of the Federal Actions Forming the Basis
of the Board’s Actions in This Docket
Based on the foregoing, the three federal actions that form the basis for Board action in
this update docket are the following, listed in chronological order:
March 5, 2005 (70 Fed. Reg. 10776)
Amendments to the hazardous waste manifest
system. (Begun by the Board in consolidated
docket R06-5/R06-6/R06-7 (Jan. 5, 2006) and
concluded in this docket.)
September 8, 2005 (70 Fed. Reg. 53420)
The Standardized Permit Rule. (Adopted by the
Board in consolidated docket R06-16/R06-
17/R06-18 (Nov. 16, 2006) and corrected in this
docket.)
April 4, 2006 (71 Fed. Reg. 16862)
Paperwork reduction amendments, primarily
directed towards Environmental Performance
Track Program facilities.
July 14, 2006 (71 Fed. Reg. 40254)
Corrections to various rules.
July 28, 2006 (71 Fed. Reg. 42928)
Conditional exclusion of CRTs that are reused or
recycled from regulation as hazardous waste.

5
Other Federal Actions Having a Direct Impact on the
Illinois RCRA Subtitle C Regulations
In addition to the amendments to the federal RCRA Subtitle C regulations, amendments
to certain other federal regulations occasionally have an effect on the Illinois hazardous waste
rules. Most notably, 35 Ill. Adm. Code 720.111 includes several incorporations of federal
regulations by reference. The incorporated regulations include segments of various USEPA
environmental regulations, Nuclear Regulatory Commission (NRC) rules, and United States
Department of Transportation (USDOT) hazardous materials transportation regulations that
USEPA has incorporated into the federal hazardous waste rules.
The latest available version of the
Code of Federal Regulations
is now the 2007 edition
for Titles 10, 33, 40, and 49. Each of these is incorporated by reference in Section 720.111 of
the hazardous waste regulations. The Board amends the incorporations of these federal
regulations by reference to include the 2007 edition of the
Code
. This assures that all USDOT
amendments through September 30, 2007, all NRC regulations through December 31, 2006, and
all Coast Guard and USEPA amendments through June 30, 2007, are included in the
incorporations of the pertinent regulations by reference.
As of the date of this opinion and the accompanying order, the Board has found only
minor sets of amendments to the incorporated materials in Section 720.111 past the date of the
2007 edition of the
Code of Federal Regulations
. These amendments update incorporated
segments of the
Code of Federal Regulations
, but it is unlikely that those amendments affect the
implementation of the federal hazardous waste requirements. Nevertheless, the Board updated
the incorporations to include the later federal amendments. The
Federal Register
citations to the
later amendments that are added to the incorporations by reference are listed in Table 2, which
begins on page 70 of this opinion.
PUBLIC COMMENTS
The Board adopted a proposal for public comment in this matter on March 20, 2008.
Notices of Proposed Amendments relating to this proceeding appeared in the April 11, 2008
issue of the
Illinois Register
, at 32 Ill. Reg. 4915 (Part 703), 4970 (Part 720), 5030 (Part 721),
5174 (Part 722), 5216 (Part 723), 5228 (Part 724), 5429 (Part 725), 5605 (Part 726), 5685 (Part
727), 5697 (Part 728), and 5904 (Part 739). The Board accepted public comments on the
proposal until May 27, 2008, the first business day following 45 days after publication. The
Board here adopts the amendments. The Board will delay filing any adopted rules with the
Secretary of State for 30 days after adoption, particularly to allow additional time for USEPA to
review the adopted amendments before they are filed and become effective.
On April 5, 2007, the Agency submitted a letter to Board staff relating to the prior
consolidated update docket, UIC Update, USEPA Amendments (January 1, 2005 through June
30, 2005, R06-16, RCRA Subtitle D Update, USEPA Amendments (January 1, 2005 through
June 30, 2005), R06-17, RCRA Subtitle C Update (January 1, 2005 through June 30, 2005 and
March 23, 2006), R06-18 (Nov. 16, 2006) (consolidated). The Agency letter relates to the
amendments adopted in consolidated update docket R06-16/R06-17/R06-18. The Agency

6
neither timely filed this letter as a public comment during the comment period of consolidated
docket R06-16/R06-17/R06-18 (
see
35 Ill. Adm. Code 102.108(a)) nor as a motion for
consideration following adoption of the amendments in that docket (
see
35 Ill. Adm. Code
101.520, 101.902, and 102.700).
The Board has regarded the Agency letter as a public comment on the existing rules. The
letter raised seven areas of concern over the amendments adopted in that prior RCRA update.
Thus, the Board has entered the letter into the consolidated docket R06-16/R06-17/R06-18 as PC
3 and into the present consolidated R07-5/R07-14 docket as PC 1, to give consideration to the
issues that the letter raises. The Agency comment is described as follows:
PC 1 April 5, 2007 letter from Kim Geving, Assistant Counsel, Division of Legal
Counsel, Illinois Environmental Protection Agency (received April 10, 2007).
The Board has revised the text of the rules to incorporate some changes based on the
Agency comments and declined to make other changes suggested by the Agency. The
discussion that begins on page 9 of this opinion considers the issues raised by the Agency
comments.
After adoption of the March 20, 2008 proposal for public comment, the Board received
other communications relating to the proposed amendments. These included a series of e-mails
from JCAR, which the Board has docketed as public comments, and a single set of comments
filed by the Agency. These comments are described as follows:
PC 2 April 7, 2008 e-mail from Erin Conley, Board staff,
1
to Michael J. McCambridge,
Board hearing officer, forwarding corrections suggested by Deborah Connelly, JCAR staff.
PC 3 April 8, 2008 e-mail from Erin Conley, Board staff, to Michael J. McCambridge,
Board hearing officer, forwarding corrections suggested by Deborah Connelly, JCAR staff.
PC 4 April 14, 2008 e-mail from Kimberly Geving, Assistant Counsel, Division of
Legal Counsel, Agency, to Michael J. McCambridge, Board hearing officer, forwarding an e-
mail exchange with Deborah Connelly, JCAR staff, regarding issues relating to the text of the
amendments.
PC 5 April 14, 2008 e-mail from Erin Conley, Board staff, to Michael J. McCambridge,
Board hearing officer, forwarding a request by Deborah Connelly, JCAR staff, for clarification
of one aspect of the regulations, with attached April 15, 2008 explanation by Michael J.
McCambridge in direct response.
PC 6 April 14, 2008 e-mail from Erin Conley, Board staff, to Michael J. McCambridge,
Board hearing officer, forwarding April 8, 2008 and April 9, 2008 requests by Deborah
1
Ms. Conley was the Board’s Rules Coordinator through April 15, 2008, when she left to take a
position with the Department of Commerce and Economic Opportunity.

7
Connelly, JCAR staff, for clarification of one aspect of the regulations and offering a potential
correction, with attached April 15, 2008 explanations by Michael J. McCambridge in direct
responses.
PC 7 April 14, 2008 e-mail from Erin Conley, Board staff, to Michael J. McCambridge,
Board hearing officer, forwarding corrections suggested by Deborah Connelly, JCAR staff.
PC 8 May 20, 2008 “Comments of the Illinois Environmental Protection Agency” from
Kimberly Geving, Assistant Counsel, Division of Legal Counsel, Agency.
In addition to these public comments, the Board received copies of the text of the
amendments from JCAR that indicate revisions that JCAR made to the text of the amendments
before publishing that text in the
Illinois Register
. The Board has interpreted that series of
documents as a series of suggested corrections to the text.
The Agency stated its position on several aspects of the amendments in response to
invitations for comment on specific issues that the Board included in the March 20, 2008
proposal for public comment. A summary of those specific Agency comments appears at the
appropriate segments of the following discussion of the amendments.
The Board has made a number of minor, non-substantive revisions in the text of the
amendments in response to the various documents received from JCAR and the Agency. None
of those revisions warrant specific discussion in this opinion. The Board directs the attention of
interested persons to Table C, which begins on page 135 of this opinion, which is a summary
listing of all changes made in the text of the rules as it appeared in the March 20, 2008 proposal
for public comment. The Board has declined to make a number of suggested revisions. Table D,
which begins on page 148 of this opinion, is a summary listing of all changes that the Board has
declined to make.
DISCUSSION
The following discussion begins with a description of the types of deviations the Board
makes from the literal text of federal regulations in adopting identical-in-substance rules. It is
followed by substantive discussions topically arranged of the substantive amendments and
actions involved in this proceeding. The first substantive discussion addresses the issues raised
by the Agency in PC1. A second substantive discussion considers irregularities in the text of the
rules that the Board has noticed over the last year or so. These are followed by a series of three
substantive discussions of the federally derived amendments involved in this consolidated
docket. This series is organized by federal subject matter, appearing in chronological order of
the relevant
Federal Register
notices involved.
General Revisions and Deviations from the Federal Text
In incorporating the federal rules into the Illinois system, some deviation from the federal
text is unavoidable. This deviation arises primarily through differences between the federal and
state regulatory structure and systems. Some deviation also arises through errors in and

8
problems with the federal text itself. The Board conforms the federal text to the Illinois rules
and regulatory scheme and corrects errors found in the text in the course of these routine update
rulemakings.
In addition to the amendments derived from federal amendments, the Board often finds it
necessary to alter the text of various passages of the existing rules as provisions are opened for
update in response to USEPA actions. This involves correcting deficiencies, clarifying
provisions, and making other changes that are necessary to establish a clear set of rules that
closely parallel the corresponding federal requirements within the codification scheme of the
Illinois Administrative Code
.
The Board updates the citations to the
Code of Federal Regulations
to the most recent
version available. As discussed above, the most recent versions of the
Code of Federal
Regulations
available to the Board are the January 1, 2006 edition for NRC regulations (Title
10), the July 1, 2005 edition for Coast Guard and USEPA regulations (Titles 33 and 40,
respectively), and the October 1, 2005 edition for USDOT regulations (Title 49). Thus, the
Board has updated all citations to Title 10 to the 2006 edition of the
Code of Federal Regulations
and citations to Titles 33, 40, and 49 to the 2005 edition, adding references to later amendments
using their appropriate
Federal Register
citation, where necessary.
The Board substituted “or” for “/” in most instances where this appeared in the federal
base text, using “and” where more appropriate. The Board further used this opportunity to make
a number of corrections to punctuation, grammar, spelling, and cross-reference format
throughout the opened text. We changed “who” to “that” and “he” or “she” to “it,” where the
person to which the regulation referred was not necessarily a natural person, or to “he or she,”
where a natural person was evident; changed “which” to “that” for restrictive relative clauses;
substituted “must” for “shall”; capitalized the section headings and corrected their format where
necessary; and corrected punctuation within sentences.
In addition, the federal rules have been edited to establish a uniform usage throughout the
Board’s regulations. For example, with respect to “shall,” “will,” and “may,” “must” is used
when an action is required by the rule, without regard to whether the action is required of the
subject of the sentence or not. “Shall” is no longer used, since it is not used in everyday
language. Thus, where a federal rule uses “shall,” the Board substitutes “must.” This is a break
from our former practice where “shall” was used when the subject of a sentence has a duty to do
something. “Will” is used when the Board obliges itself to do something. “May” is used when
choice of a provision is optional. “Or” is used rather than “and/or,” and denotes “one or both.”
“Either . . . or” denotes “one but not both.” “And” denotes “both.”
The Joint Committee on Administrative Rules has requested that the Board refer to the
United States Environmental Protection Agency in the same manner throughout all of our bodies
of regulations—
i.e.
, air, water, drinking water, RCRA Subtitle D (municipal solid waste
landfill), RCRA Subtitle C (hazardous waste), underground injection control (UIC), etc. The
Board has decided to refer to the United States Environmental Protection Agency as “USEPA.”
The Board will continue this conversion in future rulemakings as additional sections become

9
open to amendment. The Board will further convert “EPA” used in federal text to “USEPA,”
where USEPA is clearly intended.
The Board has assembled tables to aid in the location of these alterations and to briefly
outline their intended purpose. Table A sets forth the miscellaneous deviations from the federal
text, and Table B itemizes the corrections to the pre-amended base text of the rules in detail.
Table A begins on page 103 of this opinion, and Table B begins on page 118. There is no further
discussion of most of the deviations and revisions elsewhere in this opinion.
Discussion of the Issues Raised by the Agency in PC 1 and
of the Actions Taken in Response in This Docket
On April 5, 2007, the Agency submitted a letter to Board staff relating to the prior
consolidated update docket, UIC Update, USEPA Amendments (January 1, 2005 through June
30, 2005, R06-16, RCRA Subtitle D Update, USEPA Amendments (January 1, 2005 through
June 30, 2005), R06-17, RCRA Subtitle C Update (January 1, 2005 through June 30, 2005 and
March 23, 2006), R06-18 (Nov. 16, 2006) (consolidated). The letter raised seven areas of
concern over the amendments adopted in that prior RCRA update. The Board entered the letter
into the consolidated docket R06-16/R06-17/R06-18 as PC 3 and into the present consolidated
R07-5/R07-14 docket as PC 1, to give consideration to the issues that the letter raises.
After review of the Agency letter, the Board has concluded that limited revisions are
necessary to the rules. While the letter raises the same issues that the Agency raised by its June
30, 2006 comments in consolidated update docket R06-16/R06-17/R06-18 (PC 1), examination
of the issues reveals corrections that the Board had intended to make, but inadvertently did not
do so when adopting those amendments. Further, the letter indicates an additional reason to
make an Agency-suggested change that the Agency did not present to the Board at that time.
The following discussion is limited to consideration of the additional changes prompted
by the Agency’s April 10, 2007 letter. This discussion extends that which appears at pages 14
through 51 in the Board’s November 16, 2006 opinion in consolidated update docket R06-
16/R06-17/R06-18. The discussion cites the location in the November 16, 2006 opinion in that
docket of the initial discussion of the issues raised by the Agency’s comments.
Incomplete Cross-References in Section 703.350(c)(1)
The Agency notes that the Board neglected to add complete cross-references in Section
703.350(c)(1) to complete those included in corresponding 40 C.F.R. 270.260(a). The Board has
added references to Sections 702.104 and 703.110, to correspond with the federal citation to 40
C.F.R. 270.6, and Section 703.160, to correspond with the citation to 40 C.F.R. 270.1. The entry
in the table on page 288 of the Board’s November 16, 2007 opinion in consolidated docket R06-
16/R06-17/R06-18 indicates that the Board had intended to add references to Sections 703.110
and 702.160 in that docket in response to the Agency comments, but inadvertently neglected to
do so. The Board now corrects that oversight.

10
Annual Reporting Required
In the prior consolidated update docket R06-16/R06-17/R06-18, the Agency requested
that the Board retain the existing annual facility activity reporting frequency in the Illinois
regulations, even though USEPA used a biennial reporting frequency of facility activities in its
rules. The Board determined that it could not retain an annual reporting frequency consistent
with the identical-in-substance mandate of Sections 7.2(b) and 22.4(a) of the Act (415 ILCS
5/7.2(b) and 22.4(a) (2006)) after USEPA has changed to a biennial reporting requirement.
See
UIC Update, USEPA Amendments (January 1, 2005 through June 30, 2005, R06-16, RCRA
Subtitle D Update, USEPA Amendments (January 1, 2005 through June 30, 2005), R06-17,
RCRA Subtitle C Update (January 1, 2005 through June 30, 2005 and March 23, 2006), R06-18
(consolidated), slip op. at 35-36 (Nov. 16, 2006);
see also id.
at 306 (table of requested revisions
not made by the Board).
Rather than follow the Agency suggestion for an annual reporting requirement at Section
727.170(f)(1), the Board followed the biennial reporting frequency of corresponding 40 C.F.R.
267.75(a). The Board concluded that discussion as follows:
The Board must reopen Part 724 in the upcoming update docket, R07-5.
* * * The Board will include a proposal to amend 35 Ill. Adm. Code 724.175 to
provide for biennial reporting in the R07-5 proposal. That will allow public
comment on any such amendment before the Board would adopt it.
In the present docket, however, the Board amends Section 703.246(c) to
remove the references to the frequency of reporting. The Board changes “annual
report” to “facility activities report,” which is what the report is called in Section
724.175. The Board will also remove the prepositional phrase “during the
previous calendar year.” These amendments will accommodate any future
amendment of Section 724.175 to biennial reporting, or to continued annual
reporting if no such amendment is completed. * * * UIC Update, USEPA
Amendments (January 1, 2005 through June 30, 2005
, R06-16, RCRA Subtitle D

2006), R06-18 (Nov. 16, 2006) (consolidated) at p. 36
In the April 10, 2007 Agency letter (PC 1), the Agency set forth additional information
that has caused the Board to reconsider retaining an annual facility activity reporting frequency
in the Illinois regulations. The Agency letter added the following to its earlier arguments:
Section 20.1 of the Environmental Protection Act (415 ILCS 5/20.1) requires the
Agency to compile and make available an annual report regarding certain
hazardous waste operations. If we are only receiving biennial reports from
facilities, how to we effectively put together our annual reports? Additionally, the
financial assurance requirements in Section 727.240(c) require annual updates to
account for inflation. Again, how would the Agency check compliance with that
requirement if a site only provides closure cost estimates biennially? PC 1 at 3.

11
The Board agrees, based on the additional information set forth by the Agency, that
Sections 724.175 and 727.170(f) must be amended to require annual monitoring. The General
Assembly has mandated that the Agency must annually compile a report of hazardous waste
activities in Illinois and make that report available to the public, as follows:
§ 20.1. (a) The Agency shall conduct a survey and prepare and publish a
list of sites in the State where hazardous waste has been deposited, treated, or
stored.
(b) The Agency shall monitor hazardous waste processing, use, handling,
storage, and disposal practices in the State, and shall determine existing and
expected rates of production of hazardous waste.
(c) The Agency shall compile and make available to the public an annual
report identifying the types and quantities of hazardous waste generated, stored,
treated or disposed of within this State and containing the other information
required to be collected under this Section. 415 ILCS 5/20.1 (2006).
The Agency cannot meaningfully fulfill this mandate without the annual submission of the
required information by regulated facilities. By this provision, the General Assembly manifested
its intent that Illinois facilities report on an annual basis. Incorporation of a biennial reporting
frequency into the Illinois regulations that is identical-in-substance with that set forth in 40
C.F.R. 264.75 and 267.75 would be thoroughly inconsistent with the annual reporting frequency
contemplated by Section 20.1 of the Act (415 ILCS 5/20.1 (2006)).
Incorporation of an annual reporting frequency is consistent with federal law. Under
Sections 3006 and 3009 of RCRA, the State may maintain its own hazardous waste regulations
that are “substantially equivalent to” and not “less stringent than” the corresponding federal
rules. 42 U.S.C. §§ 6926(b)(1) & (e) and 6929 (2006). Section 3009 of RCRA provides,
“Nothing in this chapter shall be construed to prohibit any State or political subdivision thereof
from imposing any requirements, including those for site selection, which are more than those by
such regulations.” 42 U.S.C. § 6929 (2006). Requiring annual submission of facility activity
reports is more stringent than the federally required biennial submission, but comports with
dictates of the General Assembly.
For the foregoing reasons, the Board has amended Section 727.170(f)(1) to require
annual submission of the facility activity reports. Further, the Board has not changed the annual
reporting frequency in Section 724.175 to biennial reporting, as discussed at page 36 in the
November 16, 2006 opinion in the prior consolidated update docket, R06-16/R06-17/R06-18.
No similar revision is required for Section 703.246(c), since the Board removed the reference to
the frequency of report in the consolidated R06-16/R06-17/R06-18 docket. This change back to
an annual reporting frequency in Section 727.170(f)(1) and the retention of an annual reporting
frequency in Section 724.175 are consistent with the Board’s mandates under Sections 7.2 and
22.4(a) of the Act (415 ILCS 5/7.2 and 22.4(a) (2006)), as well as with the federal RCRA
requirements.

12
The Board made corresponding minor ancillary amendments to Sections 724.175 and
727.170(f)(1). The first is two new Board notes that are appended to Sections 724.175 and
727.170(f)(1) to explain why the Board requires annual reporting, while USEPA requires
biennial reporting. The second is a shift in phrasing based on the prior amendments to Section
703.246(c). The previously used term, “annual reporting,” describes the frequency of report
submission, but it does not describe the nature of the report itself. In consolidated docket R06-
16/R06-17/R06-18, the Board changed the term “annual report” to “facility activities report”
when removing the references to the submission frequency. The phrase “facility activities
report” is more descriptive of the report, and the Board has chosen to extend its use to Sections
724.175 and 727.170(f)(1).
Agency-Suggested Revisions Still Declined by the Board
The Board declines to further amend the text of the rules in response to any of the other
suggestions made by the Agency in its April 10, 2007 letter (PC 1). The rest of the Agency
suggestions add nothing to what the Board has already considered in the November 16, 2006
opinion in consolidated update docket, R06-16/R06-17/R06-18, based on the Agency’s June 30,
2007 comments (PC 1 in that docket).
Having fully addressed the Agency concerns in consolidated docket R06-16/R06-
17/R06-18, the Board feels no need to discuss those concerns again. The Board directs the
Agency’s attention to the following segments of the November 16, 2006 opinion in UIC Update,
USEPA Amendments (January 1, 2005 through June 30, 2005, R06-16, RCRA Subtitle D
Update, USEPA Amendments (January 1, 2005 through June 30, 2005), R06-17, RCRA Subtitle
C Update (January 1, 2005 through June 30, 2005 and March 23, 2006), R06-18 (Nov. 16, 2006)
(consolidated):

The Board will add only one point to the discussion given these issues in the prior
consolidated update docket R06-16/R06-17/R06-18. The Board adds this in clarification of the
point that the Board attempted to make when declining to make some of the Agency-requested
changes in the prior update docket. The Board cannot correct the content of federal regulations
using the identical-in-substance procedure without establishing two things: (1) there must exist
some clear indication that USEPA erred in establishing the provision at issue or in allowing the
provision to continue in the face of intervening amendments that shift its function; and (2) there
must exist some clear indication of an alternative USEPA intent that the Board can use to correct
the provision. The Board may, using the identical-in-substance procedure, retain deviations
from the federal requirements based on existing State law, as was done in this docket to retain

13
the annual reporting frequency for facility activities reports.
See
above discussion at pages 8
through 11 of this opinion. If the Board cannot use the identical-in-substance procedure to
correct the federally derived provision, the general rulemaking authority of Sections 27 and 28 of
the Act (415 ILCS 5/27 and 28 (2006)) may allow desired amendments that are “substantially
equivalent to” and not “less stringent than” the corresponding federal rules.
See id.
The Board requested comment on the revisions made to the existing rules based on the
April 10, 2007 Agency letter (PC 1). The Board received no additional information that might
have justified Board action to make additional corrections urged by the Agency.
Discussion of the Correction of Irregularities in the Base Text of the Rules
During the course of incorporating the federal April 4, 2006 amendments into the Illinois
regulations, the Board noted irregularities in segments of the base text. The text of certain
Illinois provisions does not agree with the corresponding federal provisions. Affected are the
texts of Parts 724, 725, 728, and 738. After researching the source of the irregularities, the
Board discovered errors made when adding federal amendments in two prior identical-in-
substance updates completed in 1996 and 1997. The Board also discovered an inconsistency in
the text based on a 2006 identical-in-substance update.
The Board has adopted amendments to the text of Parts 724, 725, and 728 that correct the
irregularities in the text. The corrections to Part 738, however, will require correction in a future
docket when that part is open for federal amendments.
See
22 Ill. Reg. 8038 (May 8, 1998)
(Notice of Refusal to Modify or Withdraw Rule to Meet the Objection of JCAR, explaining that
the Board would not in the future modify rules pursuant to Sections 7.2 and 22.4(a) of the Act
(415 ILCS 5/7.2 and 22.4(a) (2006)) unless the part is open to amend the rules to conform with
USEPA amendments).
The following brief discussions outline the sources and extents of the errors discovered.
The discussions describe the Board actions necessary to remove the irregularities from the text
so that it more closely conforms to the federal requirements.
Correction of Errors Made September 23, 1993 (in Docket R93-04)
The Board discovered errors in amendments adopted September 23, 1993.
See
RCRA
Update, USEPA Regulations (July 1, 1992 through December 31, 1992, R93-4 (Sep. 23, 1993).
The Board retained segments of text removed by USEPA, and the Board then reworded a
provision in a way that the Board now finds unnecessary. The present amendments correct both.
40 C.F.R. 264.571(b), (b)(1), and (b)(3) (corresponding with 35 Ill. Adm. Code
724.671(b), (b)(1), and (b)(3)):
USEPA removed the final sentence of 40 CFR
264.571(b) and paragraphs (b)(1) through (b)(3) on December 24, 1992 (at 57 Fed. Reg.
61492, 61503). The Board failed to remove the corresponding final sentence of
corresponding 35 Ill. Adm. Code 724.671(b) and the entire text of subsections (b)(1)
through (b)(3)(B)(ii) in RCRA Update, USEPA Regulations (July 1, 1992 through
December 31, 1992, R93-4 (Sep. 23, 1993). Those segments of text are removed in this

14
proceeding. The amendments to remove those segments appear as follows (also
indicating the amendment to the second to last sentence of subsection (b), which is based
on federal amendments of April 8, 2006):
b)
The owner or operator must develop a written plan for upgrading,
repairing, and modifying the drip pad to meet the requirements of
Section 724.673(b) and submit the plan to the Agency no later than
two years before the date that all repairs, upgrades and
modifications will be complete. This written plan must describe
all changes to be made to the drip pad in sufficient detail to
document compliance with all the requirements of Section
724.673. The plan must be reviewed and certified by an
independent a qualified, registered professional engineer
Professional Engineer. All upgrades, repairs, and modifications
must be completed in accordance with the following:
1)
For existing drip pads of known and documentable age, all
upgrades, repairs, and modifications must have been
completed by June 6, 1993, or when the drip pad has
reached 15 years of age, whichever comes later.
2)
For existing drip pads for which the age cannot be
documented, by June 6, 1999; but, if the age of the facility
is greater than seven years, all upgrades, repairs and
modifications must be completed by the time the facility
reaches 15 years of age or by June 6, 1993, whichever
comes later.
3)
The owner or operator may petition the Board for an
extension of the deadline in subsection (b)(1) or (b)(2) of
this Section.
A)
The owner or operator must file a petition for a
RCRA variance, as specified in 35 Ill. Adm. Code
104.
B)
The Board will grant the petition for extension if it
finds the following:
i)
The drip pad meets all of the requirements
of Section 724.673, except those for liners
and leak detection systems specified in
Section 724.673(b); and
ii)
That it will continue to adequately protect
human health and the environment.

15
40 C.F.R. 264.1101 (corresponding with 35 Ill. Adm. Code 724.1101):
USEPA
adopted 40 C.F.R. 264.1101 on August 18, 1992 (at 57 Fed. Reg. 37194, 37266). The
Board adopted corresponding 35 Ill. Adm. Code 724.1101 on September 23, 1993 in
docket R93-4. The federal language at subsection (c)(3) appeared as follows:
(3)
Throughout the active life or the containment building, if the
owner or operator detects a condition that could lead to or has
caused a release of hazardous waste, must repair the condition
promptly, in accordance with the following procedures.
The Board altered this when adopting the corresponding Illinois provision in docket R93-
4 to read as follows:
3)
Throughout the active life or the containment building, if the
owner or operator detects a condition that could lead to or has
caused a release of hazardous waste, must repair the condition
promptly. In addition, however:
Minor changes occurred in this language since that initial adoption. To revert to the
corresponding language of 40 C.F.R. 264.1101(c)(3), the Board is amending Section
724.1101(c)(3) in the present docket as follows:
3)
Throughout the active life of the containment building, if the
owner or operator detects a condition that could lead to or has
caused a release of hazardous waste, it must repair the condition
promptly. In addition, however the following is required, in
accordance with the following procedures:
Correction of Errors Made November 6, 1997 (Consolidated Docket R96-10/R97-3/R97-5)
The Board traced one series of irregularities in the text to amendments adopted on
November 6, 1997.
See
RCRA Update, USEPA Regulations (July 1, 1995, through December
31, 1995), R96-10, UIC Update, USEPA Regulations (January 1, 1996, through June 30, 1996),
R97-3, RCRA Update, USEPA Regulations (January 1, 1996, through June 30, 1996)
, R97-5
(Nov. 6, 1997). USEPA amended the hazardous waste land disposal restrictions and wastewater
pretreatment rules on April 8, 1996, partially in response to an appellate court mandate. 61 Fed.
Reg. 15566, 67-68 (Apr. 8, 1996) (in significant part responding to Chemical Waste
Management (CWM) v. EPA, 976 F.2d 2 (D.C. Cir. 1992),
cert. denied
, 113 S. Ct. 1961 (1993)).
USEPA amendments to 40 C.F.R. 268 involved federal hazardous waste regulations.
Amendments to 40 C.F.R. 148 involved the land disposal restrictions associated with the
underground injection control regulations. Those to 40 C.F.R. 403 involved wastewater
pretreatment requirements.

16
Also on April 8, 1996, in a separate notice, USEPA withdrew those segments of the
amendments pertaining to the mandate in response to intervening legislation. 61 Fed. Reg.
15660, 61 (Apr. 8, 1996) (responding to the March 26, 1996 enactment of the Land Disposal
Program Flexibility Act of 1996, Pub. L. 104-119, 100 Stat. 830). In that second notice, USEPA
withdrew amendments to 40 C.F.R. 148.1(b) and (d), 148.3, 148.4, 148.18, 148.20(a)
introductory text, 268.1(e), 268.2(k) and (l), 268.3, 268.9(d) through (g), 268.39, 268.40(e),
268.44(a), and 403.5(c) and (d). 61 Fed. Reg. at 15662. In that second notice, USEPA set forth
alternative text for 40 C.F.R. 148.18, 268.3(a), 268.39, and 268.40(e). 61 Fed. Reg. at 15662-62.
Subsequently, on June 28, 1996, USEPA corrected both its April 8, 1996 amendments
and its April 8, 1996 partial withdrawal of those amendments. 61 Fed. Reg. 33680 (June 28,
1996). USEPA corrected the text of 40 C.F.R. 148.1(d), 268.39, and 268.40(e) in a way that
affected text subject to the April 8, 1996 withdrawal of amendments.
The Board included the hazardous waste and underground injection control aspects of the
April 8, 1996 federal amendments and partial withdrawal and June 28, 1996 corrections in
consolidated docket RCRA Update, USEPA Regulations (July 1, 1995, through December 31,
1995), R96-10, UIC Update, USEPA Regulations (January 1, 1996, through June 30, 1996),
R97-3, RCRA Update, USEPA Regulations (January 1, 1996, through June 30, 1996), R97-5
(Nov. 6, 1997). The wastewater pretreatment amendments were included in the separate docket
Wastewater Pretreatment Update, USEPA Regulations (January 1, 1996, through June 30, 1996),
R97-7 (Apr. 3, 1997). The Board included both sets of the April 8, 1996 amendments in these
dockets, including the corrections of June 28, 1996 in consolidated docket R96-10/R97-3/R97-5,
but missed a small segment of the withdrawal set forth in a paragraph that preceded the
amendments to the text of the federal rules in the second April 8, 1996
Federal Register
notice.
See
61 Fed. Reg. at 15662.
Having investigated the extent of the irregularities found in the text of the Illinois rules,
the Board has determined the extent of the corrections now necessary. The Board has further
learned that no corrections are necessary to many provisions, since amendments based on the
second action of April 8, 1996, the corrections of June 28, 1996, or some later federal
amendments have already corrected the text. The following paragraphs outline the status of the
text for each federal amendment withdrawn on April 8, 1996, as well as the status of each
corresponding Illinois provision.
40 C.F.R. 148.1(b) (corresponding with 35 Ill. Adm. Code 738.101(b))
: April 8, 1996
amendment withdrawn on April 8, 1996.
Action necessary: Correction of the text of corresponding 35 Ill. Adm. Code 738.101(b)
is necessary in a future docket as follows:
b)
The requirements of this Part apply to owners or operators of the
following Class I injection wells:
hazardous waste injection wells that are
used to inject hazardous waste.
1)
Hazardous waste injection wells that are used to inject hazardous

17
waste; and
2)
Injection wells that are used to inject wastes that once exhibited a
prohibited characteristic of hazardous waste identified in Subpart
C of 35 Ill. Adm. Code 721, at the point of generation, and which
no longer exhibit the characteristic at the point of injection.
40 C.F.R. 148.1(d) (corresponding with 35 Ill. Adm. Code 738.101(d))
: April 8, 1996
amendment withdrawn on April 8, 1996, but corrected on June 28, 1996.
The text of corresponding 35 Ill. Adm. Code 738.101(d) accurately reflects the federal
text based on the June 28, 1996 corrections, so no further correction is necessary.
40 C.F.R. 148.3 (corresponding with 35 Ill. Adm. Code 738.103):
April 8, 1996
amendment withdrawn on April 8, 1996.
Action necessary: Correction of the text of corresponding 35 Ill. Adm. Code 738.103 is
necessary in a future docket as follows:
a)
The provisions of 35 Ill. Adm. Code 728.103 apply to owners or operators
of Class I hazardous waste injection wells used to inject a waste that is
hazardous at the point of generation whether or not the waste is hazardous
at the point of injection.
b)
The owner or operator of a Class I non-hazardous waste injection well that
injects waste formerly exhibiting a hazardous characteristic that has been
removed by dilution may address underlying hazardous constituents by
treating the hazardous waste, by obtaining an exemption pursuant to a
petition filed under Section 738.120, or by complying with the provisions
set forth in 35 Ill. Adm. Code 728.109.
40 C.F.R. 148.4 (corresponding with 35 Ill. Adm. Code 738.104):
April 8, 1996
amendment withdrawn on April 8, 1996.
Action necessary: Correction of the text of corresponding 35 Ill. Adm. Code 738.104 is
necessary in a future docket as follows:
The owner or operator of a Class I hazardous or non-hazardous waste
injection well may submit an application to USEPA for an extension of
the effective date of any applicable prohibition established under Subpart
B of this Part pursuant to 40 CFR 268.5. Any extension that is granted by
USEPA will be deemed an extension of the effective date of the derivative
Board rule.
40 C.F.R. 148.18 (corresponding with 35 Ill. Adm. Code 738.118):
Added April 8,
1996, but withdrawn on April 8, 1996. Withdrawal of text on April 8, 1996 set forth

18
replacement text.
The text of corresponding 35 Ill. Adm. Code 738.118 accurately reflects the federal text
based on the text set forth in the April 8, 1996 withdrawal, so no further correction is
necessary.
40 C.F.R. 148.20(a) introductory text (corresponding with 35 Ill. Adm. Code 738.120
introductory text):
April 8, 1996 amendment withdrawn on April 8, 1996.
Action necessary: Correction of the text of corresponding 35 Ill. Adm. Code 738.120(a)
is necessary in a future docket as follows:
a)
Any person seeking an exemption from a prohibition under Subpart B of
this Part for the injection of a restricted hazardous waste, including a
hazardous waste that exhibits a characteristic of hazardous waste and
which contains underlying hazardous constituents at the point of
generation, but which no longer exhibits a characteristic of hazardous
waste when injected into a Class I an injection well or wells, must submit
a petition for an adjusted standard to the Board, pursuant to Subpart D of
35 Ill. Adm. Code 104, demonstrating that, to a reasonable degree of
certainty, there will be no migration of hazardous constituents from the
injection zone for as long as the waste remains hazardous. This
demonstration requires a showing of the following:
40 C.F.R. 268.1(e) (corresponding with 35 Ill. Adm. Code 728.101(e)):
April 8, 1996
amendment withdrawn on April 8, 1996. Subsequent amendment on May 12, 1997 (at 62
Fed. Reg. 25998) set forth replacement text.
The text of corresponding 35 Ill. Adm. Code 728.101(e) accurately reflects the federal
text based on the text set forth in the May 12, 1997 amendments (as included in
consolidated docket RCRA Update, USEPA Regulations (July 1, 1996, through
December 31, 1996), R97-21, UIC Update, USEPA Regulations (January 1, 1997,
through June 30, 1997), R98-3, RCRA Update, USEPA Regulations (January 1, 1997,
through June 30, 1997), R98-5 (Aug. 20, 1998)), so no further correction is necessary.
40 C.F.R. 268.2(k) (corresponding with 35 Ill. Adm. Code 728.102 “underlying
hazardous constituent”):
April 8, 1996 amendment withdrawn on April 8, 1996.
Action necessary: Correction of the text of corresponding 35 Ill. Adm. Code 728.102 to
remove the definition of “underlying hazardous constituent” is necessary, which is
included in the present consolidated docket.
40 C.F.R. 268.2(l) (corresponding with 35 Ill. Adm. Code 728.102 “inorganic metal-
bearing waste”):
April 8, 1996 amendment withdrawn on April 8, 1996.
Action necessary: Correction of the text of corresponding 35 Ill. Adm. Code 728.102 to

19
remove the definition of “inorganic metal-bearing waste” is necessary, which is included
in the present consolidated docket.
40 C.F.R. 268.3 (corresponding with 35 Ill. Adm. Code 728.103):
Added April 8,
1996, but withdrawn on April 8, 1996. Withdrawal of text on April 8, 1996 set forth
replacement text.
The text of corresponding 35 Ill. Adm. Code 728.103 accurately reflects the federal text
based on the text set forth in the April 8, 1996 withdrawal, so no further correction is
necessary.
40 C.F.R. 268.9(d) (corresponding with 35 Ill. Adm. Code 728.109(d)):
April 8, 1996
amendment withdrawn on April 8, 1996. Subsequent amendment on May 12, 1997 (at 62
Fed. Reg. 25998) and May 11, 1999 (at 64 Fed. Reg. 25408) set forth partial replacement
text.
Action necessary: The text of corresponding 35 Ill. Adm. Code 728.109(d) partially
accurately reflects the federal text based on the text set forth in the May 12, 1997
amendments (as included in consolidated docket RCRA Update, USEPA Regulations
(July 1, 1996, through December 31, 1996), R97-21, UIC Update, USEPA Regulations
(January 1, 1997, through June 30, 1997), R98-3, RCRA Update, USEPA Regulations
(January 1, 1997, through June 30, 1997), R98-5 (Aug. 20, 1998)) and the May 11, 1999
amendments (as included in consolidated docket RCRA Update, USEPA Regulations
(January 1, 1999, through June 30, 1999), R00-5 (Dec. 2, 1999)) so only partial
correction is necessary, which is included in the present consolidated docket, as follows
(at subsection (d)(3)):
d)
A waste that exhibits a characteristic of hazardous waste under Subpart C
of 35 Ill. Adm. Code 721 is also subject to Section 728.107 requirements,
except that once the waste is no longer hazardous, a one-time notification
and certification must be placed in the generator’s or treater’s on-site files
and sent to the Agency, except for those facilities described in subsection
(f) of this Section. The notification and certification that is placed in the
generator’s or treater’s files must be updated if the process or operation
generating the waste changes or if the RCRA Subtitle D (municipal solid
waste landfill) facility receiving the waste changes. However, the
generator or treater need only notify the Agency on an annual basis if such
changes occur. Such notification and certification should be sent to the
Agency by the end of the year, but no later than Dec. 31.
1)
The notification must include the following information:
A)
The name and address of the RCRA Subtitle D (municipal
solid waste landfill) facility receiving the waste shipment;
and

20
B)
A description of the waste as initially generated, including
the applicable USEPA hazardous waste numbers, the
treatability groups, and the underlying hazardous
constituents (as defined in Section 728.102(i)), unless the
waste will be treated and monitored for all underlying
hazardous constituents. If all underlying hazardous
constituents will be treated and monitored, there is no
requirement to list any of the underlying hazardous
constituents on the notice.
2)
The certification must be signed by an authorized representative
and must state the language found in Section 728.107(b)(4). If
treatment removes the characteristic but does not meet standards
applicable to underlying hazardous constituents, then the
certification found in Section 728.107(b)(4)(D) applies.
3)
For a characteristic waste whose ultimate disposal will be into a
Class I nonhazardous waste injection well, and for which
compliance with the treatment standards set forth in Section
728.148 and Table U to this Part for underlying hazardous
constituents is achieved through pollution prevention that meets
the criteria set forth at 35 Ill. Adm. Code 738.101(d), the following
information must also be included:
A)
A description of the pollution prevention mechanism and
when it was implemented, if already complete;
B)
The mass of each underlying hazardous constituent before
pollution prevention;
C)
The mass of each underlying hazardous constituent that
must be removed, adjusted to reflect variations in mass due
to normal operating conditions; and
D)
The mass reduction of each underlying hazardous
constituent that is achieved.

.
This incorporation included the April 8, 1996 withdrawal of the amendments.
Correction of Inconsistency in Text Adopted on November 16, 2006 (Docket R06-18)
The Board discovered an inconsistency between pre-existing rules and text added on
November 16, 2006, when the Board adopted a segment of text based on USEPA’s RCRA
standardized permit rule. Examination of the text has indicated that the wording of that segment
is inconsistent with the wording used in existing similar provisions in the permitted facility and
interim status facility requirements. The present amendments alter the wording of the pre-
existing provision to agree with the wording recently adopted for the RCRA standardized permit
rule.
The RCRA standardized permit rules include containment building requirements at
subpart DD of 40 C.F.R. 267. Section 267.1104 is a provision in that subpart which allows a
waiver of the generally applicable containment building requirements. It states as follows:
Notwithstanding any other provision of this subpart, the Regional Administrator
may waive requirements for secondary containment for a permitted containment
building where:

23
(a) You demonstrate that the only free liquids in the unit are limited amounts of
dust suppression liquids required to meet occupational health and safety
requirements, and
(b) Containment of managed wastes and dust suppression liquids can be assured
without a secondary containment system. 40 C.F.R. 267.1104 (2007).
When adding this provision to the Illinois regulations as 35 Ill. Adm. Code 727.900(e), in
UIC Update, USEPA Amendments (July 1, 2005 through Dec. 31, 2005), R06-16, RCRA
Subtitle D Update, USEPA Amendments (July 1, 2005 through Dec. 31, 2005), R06-17, RCRA
Subtitle C Update, USEPA Amendments (July 1, 2005 through Dec. 31, 2005 and March 23,
2006), R06-18 (Nov. 16, 2006) (consolidated), the Board changed the provision to read as
follows:
e)
Alternatives to secondary containment requirements. Notwithstanding
any other provision of this Section, the Agency must, in writing, allow the
use of alternatives to the requirements for secondary containment for a
permitted containment building where the Agency has determined that the
facility owner or operator has adequately demonstrated both of the
following:
1)
The only free liquids in the unit are limited amounts of dust
suppression liquids required to meet occupational health and safety
requirements, and
2)
The containment of managed wastes and dust suppression liquids
can be assured without a secondary containment system. 35 Ill.
Adm. Code 727.900(e).
The RCRA regulations include containment building requirements in the permitted
facility and interim status facility rules at Subpart DD of 40 C.F.R. 264 and 265. Nearly
identical sections 264.1101(e) and 265.1101(e)
2
in those subparts allow a waiver of the generally
applicable containment building requirements in language that is very similar to that of section
267.1104. Section 264.1101(e) states as follows:
(e) Notwithstanding any other provision of this subpart the Regional
Administrator may waive requirements for secondary containment for a permitted
containment building where the owner operator demonstrates that the only free
liquids in the unit are limited amounts of dust suppression liquids required to
meet occupational health and safety requirements, and where containment of
2
Section 265.1102(e) differs from section 264.1102(e) only in the addition of a comma after the
introductory clause, “notwithstanding . . . this subpart,” and the addition of a conjunction to
correct “owner operator” to “owner or operator.”

24
managed wastes and liquids can be assured without a secondary containment
system. 40 C.F.R. 264.1101(e) (2007).
The Board added 35 Ill. Adm. Code 724.1101 and 725.1101 in RCRA Update, USEPA
Regulations (July 1, 1992 through December 31, 1992, R93-4 (Sep. 23, 1993), replacing the
permissive “may waive” language with language that the Agency cannot impose requirements
where the owner or operator has made certain demonstrations. This was to avoid conferring
unfettered discretion on the Agency whether to impose requirements or not.
See id.
, opinion, at
pp. 31-33. After years with only minor, non-substantive amendment, the identical texts of
Sections 724.1101(e) and 725.1101(e) read as follows:
e)
Notwithstanding any other provision of this Subpart DD the Agency must
not require secondary containment for a permitted containment building
where the owner operator demonstrates that the only free liquids in the
unit are limited amounts of dust suppression liquids required to meet
occupational health and safety requirements, and where containment of
managed wastes and liquids can be assured without a secondary
containment system. 35 Ill. Adm. Code 724.1101(e) and 725.1101(e).
This text in Sections 724.1101(e) and 725.1101(e) differs from that of Section 727.900(e), as
recently adopted in consolidated docket R06-16/R06-17/R06-18 in a way that could be construed
as substantive. The statement, “the Agency must not require secondary containment . . . where
the owner or operator has demonstrates,” in Sections 724.1101(e) and 725.1101(e) is different
from that in Section 727.900(e), “the Agency must, in writing, allow the use of alternatives to the
requirements for secondary containment . . . where the Agency has determined that the facility
owner or operator has adequately demonstrated.” The fact that the corresponding statement in
40 C.F.R. 264.1101(e) and 265.1101(e) is substantially the same as that used in 40 C.F.R.
267.1104,
3
indicates that USEPA does not intend a difference in the application of these
provisions.
Since it appears that USEPA intends the same meaning in 40 C.F.R. 267.1104 as it does
in 40 C.F.R. 264.1101(e) and 265.1101(e), the Board will amend corresponding Sections
724.1101(e) and 725.1101(e) to conform with the text of 727.900(e), as more recently adopted in
consolidated docket R06-16/R06-17/R06-18. The Board will amend Sections 724.1101(e) and
725.1101(e) as follows:
4
3
As is indicated by the quoted segments above, the principal changes are that USEPA
subdivided 40 C.F.R. 267.1104 into subsections and used its more colloquial second-person
form, “you demonstrate.” USEPA codified 40 C.F.R. 264.1101(e) and 265.1101(e) as a single
subsection and used the more formalized form, “the owner or operator demonstrates.”
4
The only difference between the texts of the two respective provisions are that the amendments
will add a comma after the introductory clause in Section 724.1101(e) that already exists in the
similar clause in Section 725.1101(e). The Board has included the addition of the conjunction to
“owner or operator” in both provisions, which was formerly omitted from the text.

25
e)
Notwithstanding any other provision of this Subpart DD, the Agency
must, in writing, not require allow the use of alternatives to the
requirements for secondary containment for a permitted containment
building where the Agency has determined that the facility owner or
operator demonstrates has adequately demonstrated that the only free
liquids in the unit are limited amounts of dust suppression liquids required
to meet occupational health and safety requirements, and where
containment of managed wastes and liquids can be assured without a
secondary containment system. 35 Ill. Adm. Code 724.1101(e) and
725.1101(e).
Discussion of the Particular Federal Actions Involved in This Docket
Regulatory Burden Reduction Amendments--Parts 703, 720, 721, 724, 725, 726, and 728
5
On April 4, 2006 (71 Fed. Reg. 16862), USEPA adopted a series of amendments to
various rules as part of a “Burden Reduction Initiative.” USEPA revised 79 separate provisions
in the hazardous waste regulations. These revisions are best summarized by quotation of
USEPA’s discussion of the amendments. USEPA characterized the several revisions as falling
within 10 categories of provisions affected:
To effectively present the large number of regulatory changes we are finalizing,
we have divided these changes into ten categories or groups of changes; they are:
(1) The amount of time records must be kept; (2) certification by a professional
engineer; (3) option to follow the Integrated Contingency Plan Guidance; (4)
option to follow the Occupational Safety and Health Administration (OSHA)
regulations for emergency training; (5) clarifications and elimination of obsolete
regulatory language; (6) elimination of selected recordkeeping and reporting
requirements; (7) decreased self-inspection frequency for selected hazardous
waste management units; (8) selected changes to the requirements for record
retention and submittal of records; (9) changes to the requirements for document
submittal; and (10) reduced frequency for report submittals. 71 Fed. Reg. 16862,
16863 (Apr. 4, 2006).

726.202, 726.203, 728.107, and 728.109.

26
In a more extensive table in the
Federal Register
notice adopting these amendments, USEPA
more fully summarizes what amendments it undertook to effect each of these 10 points.
See
71
Fed. Reg. 16862, 16864 (Apr. 4, 2006).
Many of the revisions pertain only to facilities in USEPA’s National Environmental
Performance Track Program (Program). USEPA described the program and its member facilities
in the following new definition added to the hazardous waste regulations:
The National Environmental Performance Track Program is a voluntary, facility
based, program for top environmental performers. Facility members must
demonstrate a good record of compliance, past success in achieving
environmental goals, and commit to future specific quantified environmental
goals, environmental management systems, local community outreach, and annual
reporting of measurable results. 40 C.F.R. 260.10 (2005), as amended at 71 Fed.
Reg. 16862, 16902 (Apr. 4, 2006) (new definition of “Performance Track member
facility”).
The Board does not review the substance and merits of the underlying federal action in
an identical-in-substance proceeding, except to the extent that it may be necessary to do so in
order to incorporate the federal provisions into the Illinois regulations. Persons interested in the
details of the federal amendments should consult the April 4, 2006
Federal Register
notice.
The Board incorporated the April 4, 2006 federal amendments without substantive
deviation from the corresponding federal text. The deviations from the text of the federal
amendments are restricted to those structural and stylistic changes needed to make the text
comport with the
Illinois Register
format and the Board’s preferred style and to add clarity and
ease of use for the regulated community. The Table A, which begins on page 103 of this
opinion, itemizes the various revisions made in the federal text in adapting it into the State
regulations.
Only one of these revisions to the federal amendments warrants mention in this
discussion. The Board added a Board note to the definition of “Performance Track member
facility” in section 720.110. That note is intended to provide sources of information about
USEPA’s Environmental Performance Track Program for the benefit of the regulated
community. The note refers to the 2000 and 2004
Federal Register
notices that initiated and
later amended the Program, respectively. The note further sets forth the address of the website
that USEPA has established relating to the program.
The USEPA website explains the Program and how an entity can become a part of the
Program. It discloses that there are presently 14 entities in Illinois that are program members.
6
6
These facilities currently are 3M, in Cordova; Akzo Nobel Aerospace Coatings, in Waukegan;
Baxter Healthcare, in McGaw Park; Baxter Healthcare, in Round Lake; Bridgestone/Firestone
North American Tire LLC, in Bloomington; Chicago White Metal Casting, Inc., in Bensenville;
E & T Controls, Inc., in Rochelle; Fujifilm Hunt Chemicals U.S.A., Inc., in Rolling Meadows;

27
While it may be possible to define “Performance Track member facility” by listing these 14
entities, the Board would prefer not to do so. The language of the definition that the Board has
chosen more closely follows the corresponding USEPA definition in 40 C.F.R. 260.10. Further,
it would be cumbersome to require future amendment of the Illinois definition by rulemaking as
USEPA amends its listing of member facilities. But, the Board has “fleshed out” the definition
by adding the reference to the Internet site where USEPA maintains its current listing of member
facilities.
The Board requested public comment on the incorporation of the April 4, 2006 federal
Burden Reduction Initiative amendments. The Board received no comments relating to this
issue.
Corrections to Hazardous Waste and Used Oil Regulations--Parts 703, 720, 721, 722, 724,
725, 726, 728, and 739
7
On July 14, 2006 (71 Fed. Reg. 40254), USEPA adopted a number of corrections to
errors in its hazardous waste, universal waste, and used oil rules. USEPA characterized the
errors as arising “as a result of printing omissions, typographical errors, misspellings, citations to
paragraphs and other references that have been deleted or moved to new locations without
correcting the citations, and similar mistakes appearing in numerous final rules.” 71 Fed. Reg.
40254 (July 14, 2006). USEPA further stated, “The application, implementation, and
enforcement of the regulations addressed in this rule are not changed in any way.”
Id.
Affected
were more than 200 provisions from every part of the federal hazardous waste, universal waste,
and used oil regulations. Some provisions had multiple corrections. Nearly all of the federal
corrections involved very minor changes in the text, but a small number of the changes affected
the text more significantly.
The Board has reviewed each federal correction to determine what action is necessary to
amend the Illinois regulations. The Board does not review the substance and merits of the
underlying federal action in an identical-in-substance proceeding, except to the extent that it may
be necessary to do so in order to incorporate the federal provisions into the Illinois regulations.

28
Persons interested in the details of the federal amendments should consult the July 14, 2006
Federal Register
notice. Discussion of particular federal actions appears below only where some
unusual aspect of that action of the provision involved warrants consideration. Those segments
are arranged topically immediately following a general description of the USEPA corrections
and the Board responses.
USEPA made 464 individual corrections to a wide variety of federal provisions in 14
parts of the federal rules. The Board has made corrections in this docket in response to 151 of
the USEPA corrections to several segments of the rules. No Board action was necessary on 309
of the federal corrections, for a variety of reasons. The principal reason for no Board action at
this time is that the Board has already made a great number of the corrections in prior
rulemakings. Another frequent reason for no Board action is that there is no counterpart in the
Illinois rules for a limited number of the federal provisions corrected.
The Board has declined to take action on four of the federal corrections. Three of those
federal corrections were clear errors that the Board has chose not to replicate.
8
The Board has determined that the final two USEPA corrections were significant
substantive errors. Despite a stated intent not to change the substance of 40 C.F.R. 261.21(a)(3)
and (a)(4) (corresponding with 35 Ill. Adm. Code 721.121(a)(3) and (a)(4)), the Board perceives
that the corrections did quite the opposite. Rather than make those two significant changes in the
rules, the Board has chosen to depart from the federal text and retain those two segments of the
rules as previously corrected by the Board. Retaining the previously corrected text is a
significant departure from the corrections adopted by USEPA. Discussion of the Board’s
deviation from those two federal corrections appears below, on pages 28 through 56 of this
opinion.
Finally, the Board has decided to follow the USEPA lead and change the spelling of
“exceedence” to “exceedance” in Sections 724.323(b)(1), 724.404(b)(1), 725.324(b)(1), and
725.403(b)(1) to correspond with the corrections to 40 C.F.R. 264.223(b)(1), 264.304(b)(1),
265.224(b)(1), and 265.303(b)(1). The Board had previously opted to follow the traditional form
for such Latinate words and use “exceedence” in SDWA Update, USEPA Amendments (July 1,
2000 through December 31, 2000; Radionuclides), R01-20, at pp. 9-10 (Oct. 4, 2001) and in
RCRA Subtitle C Update, USEPA Amendments (July 1, 2002 through December 31, 2002)
,
R03-18, at p. 64-65 (June 5, 2003). Making this change is discussed below, at pages 56 through
57 of this opinion.
Table 3, which begins on page 72 of this opinion, briefly outlines the federal corrections
of July 14, 2006. It further indicates the corresponding Illinois provision and whether Board
action to amend that provision was necessary based on the federal correction. Where action was
necessary, the table indicates the nature of the action. Where no action was necessary, the table
indicates why no action was necessary. The following discussion is limited to consideration of

These are one correction to 40 C.F.R. 265.405(a)(1) and two to appendix VI to 40 C.F.R. 264.
The nature of each is described in the appropriate entry in the following table.

the significant deviations that the Board has made while incorporating the federal corrections
into the Illinois rules.
Corrections to 40 C.F.R. 261.21(a)(3) (corresponding with Section 721.121(a)(3))
The USEPA corrections to the definition of “ignitable waste” at 40 C.F.R. 261.21(a)(3)
and (a)(4) present problems. These two paragraphs define what is “ignitable compressed gas”
and “oxidizer” for the purposes of defining “ignitable waste.” The problems with paragraphs
(a)(3) and (a)(4) arise from USEPA incorporating outdated language from the 1980 version of
USDOT regulations into these provisions. Resolution of the problems associated with each
provision presents unique considerations, so the Board discusses each individually.
Nevertheless, some aspects of the following discussion of 40 C.F.R. 261.21(a)(3) are pertinent
also to the discussion of paragraph (a)(4) that follows. Thus, the discussion of paragraph (a)(4)
will refer back to the appropriate segments of the discussion of paragraph (a)(3).
The federal corrections to 40 C.F.R. 261.21(a)(3) warrant further consideration. This
provision defines the characteristic of ignitability. Federal paragraph (a)(3) designates any waste
that is an “ignitable compressed gas” as “ignitable waste.” Formerly, these paragraphs defined
what is an “ignitable compressed gas” by reference to USDOT regulations, as follows:
§ 261.21 Characteristic of ignitability.
(a) A solid waste exhibits the characteristic of ignitability if a representative
sample of the waste has any of the following properties:
* * *
(3) It is an ignitable compressed gas as defined in 49 CFR 173.300 and as
determined by the test methods described in that regulation or equivalent test
methods approved by the Administrator under §§ 260.20 and 260.21. 40 C.F.R.
261.21(a)(3) (1980);
see
45 Fed. Reg. 33084, 33121-22 (May 19, 1980).
The 1980 version of 49 C.F.R. 173.300, as relied on by USEPA in 40 C.F.R.
261.21(a)(3), defined the hazard class “flammable compressed gas” based on the use of methods
then current. The 1980 version of 49 C.F.R. 173.300 provided in significant part as follows:
§ 173.300 Definitions.
(a) Compressed gas. The term “compressed gas” shall designate any material or
mixture having in the container an absolute pressure exceeding 40 p.s.i. at 70° F.
or, regardless of the pressure at 70° F., having an absolute pressure exceeding 104
p.s.i. at 130° F.; or any liquid flammable material having a vapor pressure
exceeding 40 p.s.i. absolute at 100° F. as determined by ASTM Test D–323.
(b) Flammable compressed gas. Any compressed gas as defined in paragraph (a)
of this section shall be classed as “flammable gas” if any one of the following

30
occurs:
(1) Either a mixture of 13 percent or less (by volume) with air forms a flammable
mixture or the flammable range with air is wider than 12 percent regardless of the
lower limit. These limits shall be determined at atmospheric temperature and
pressure. The method of sampling and test procedure shall be acceptable to the
Bureau of Explosives and approved by the Associate Director for [the Office of
Hazardous Materials Research].
(2) Using the Bureau of Explosives’ Flame Projection Apparatus (see Note 1),
the flame projects more than 18 inches beyond the ignition source with valve
opened fully, or, the flame flashes back and burns at the valve with any degree of
valve opening.
(3) Using the Bureau of Explosives’ Open Drum Apparatus (see Note 1), there is
any significant propagation of flame away from the ignition source.
(4) Using the Bureau of Explosives’ Closed Drum Apparatus (see Note 1), there
is any explosion of the vapor-air mixture in the drum.
Note 1: A description of the Bureau of Explosives’ Flame Projection Apparatus,
Open Drum Apparatus, Closed Drum Apparatus, and method of tests may be
procured from the Bureau of Explosives. 49 C.F.R. 173.300 (1980).
Problems have arisen, however, through USEPA’s use of this 1980 USDOT definition of
the hazard class “flammable compressed gas”. USEPA did not merely lift the USDOT definition
from 49 C.F.R. 173.300 (1980); the definition has become altered. Part of the alteration
occurred in 1980, when USEPA initially adopted 40 C.F.R. 261.300. Further alteration has
resulted from the passage of time. Even more alteration occurred in the July 14, 2006
corrections.
The initial USEPA alteration of the USDOT definition dates back to initial adoption of
40 C.F.R. 261.21(a)(3) in 1980. USEPA altered the terms used. Under the 1980 version of the
USDOT regulations, the definition at 49 C.F.R. 173.300(b) actually describes the hazardous
materials hazard class as “flammable compressed gas” (or “flammable gas”). It does not
describe it as “ignitable compressed gas.” When USEPA initially adopted 40 C.F.R.
261.21(a)(3), and until the July 14, 2006 corrections, 40 C.F.R. 261.21(a)(3) stated that
“ignitable waste” includes “ignitable compressed gas as defined in 49 CFR 173.300 and as
determined by the test methods described in that regulation . . ..”
The discussion that accompanied adoption of 40 C.F.R. 261.21 reveals that USEPA
intended a difference between a USDOT “flammable liquid” and a RCRA “ignitable liquid
waste,” so it chose to use “ignitable” instead of “flammable” in its definition of the characteristic
of ignitability. On the other hand, the discussion also shows that USEPA did not intend a
difference between a USDOT “flammable compressed gas” and a RCRA “ignitable compressed
gas,” despite a similar shift in terms. USEPA stated as follows in this regard:

31
EPA adopted the Department of Transportation’s definitions of ignitable
compressed gas and oxidizer and borrowed heavily from the Department of
Transportation’s definition of non-liquid ignitable because it believed these
definitions adequately reflected routine waste management conditions. At the
same time, it chose a flashpoint limit for ignitable liquid wastes different from
that specified by the Department of Transportation’s “flammable” liquid category
because it believed that the flashpoint limit specified by the Department of
Transportation did not fully reflect conditions likely to be encountered during
routine waste management.
* * * * *
EPA does not believe that its ignitable liquids category will create undue
confusion in the regulated community. The term “ignitable” was specifically
chosen to eliminate confusion between EPA’s “ignitable” liquids category and the
Department of Transportation’s “flammable” liquids category. 45 Fed. Reg.
33084, 33108 (May19, 1980).
USEPA intended “ignitable” to be synonymous with “flammable” when it comes to
compressed gas, while it also clearly intended a shift in meaning with the shift in terms from
“flammable” to “ignitable” with regard to liquids. Thus, USEPA apparently had two contrary
intents by the same shift of phrasing in the same provision.
The continued use of “ignitable” in place of the USDOT term “flammable” is potentially
confusing in this context. One could easily infer a shift in meaning. The Board believes that
USEPA should have reduced the potential for ambiguity by retaining the original USDOT words
“flammable compressed gas” (or the equivalent USDOT term, “flammable gas”) and not using
“ignitable compressed gas.”
See
45 Fed. Reg. 33084, 33122 (May19, 1980).
A second, more significant problem with 40 C.F.R. 261.21(a)(3) relates to the methods
used for determining whether a material belongs within the class. This problem relates to the
extreme age of the methods used, and it culminated in 1990, when USDOT removed 49 C.F.R.
173.300 from its regulations.
See
55 Fed. Reg. 52402 (Dec. 21, 1990). The 1990 amendments
changed the methods used for determining whether a material falls within the class, and they
replaced the former “flammable compressed gas” hazard class with a new one, “flammable gas.”
The first method used for testing flammability pursuant to the 1980 USDOT rule were
those “acceptable to the Bureau of Explosives and approved by the director, Pipeline and
Hazardous Materials Technology, U.S. Department or Transportation.” This referenced no
distinct methods.
The subsequent methods used for testing flammability under the 1980 rule were definite
methods produced by the Bureau of Explosives. The USDOT rule referred to the “Bureau of
Explosives’ Flame Projection Apparatus,” the “Bureau of Explosives’ Open Drum Apparatus,”
and the “Bureau of Explosives’ Closed Drum Apparatus,” none of which was defined with

32
greater particularity as to author, document number, date, availability, etc. An Internet search
has led the Board to an undated document entitled, “Aerosol Flame Projection Tests,” which is
available for download from the Association of American Railroads, Bureau of Explosives,
Operations and Maintenance Department (from Internet address http://boe.aar.com/boe-
download.htm). The Board could not determine a date for the Bureau of Explosives method, but
the document dates back to at least the 1964 republication of 49 C.F.R. 73.300 (the forerunner to
49 C.F.R. 173.300).
See
29 Fed. Reg. 18652, 18743 (Dec. 29, 1964) (republication of 49 C.F.R.
173 to embrace a series of earlier amendments).
In 1990 USDOT significantly amended its hazardous materials transportation regulations.
USDOT changed the pertinent USDOT rules in two ways. First, USEPA redesignated the
hazard class to “flammable gas.” USDOT removed its 49 C.F.R. 173.300(b) definition of
“flammable compressed gas.” USDOT replaced this with a new class of hazardous material
called “flammable gas” at 49 C.F.R. 173.115. Second, USDOT updated the methods for
determining whether a material is “flammable gas.” The method approved by the “director,
Pipeline and Hazardous Materials Technology, U.S. Department of Transportation,” as
contemplated in the 1980 version of 49 C.F.R. 173.300, changed from the undated Bureau of
Explosives methods to a distinct method from the American Society for Testing and Materials
(ASTM). The new method was ASTM Method E 681-85, “Standard Test Method for
Concentration Limits of Flammability of Chemicals (Vapors and Gases).”
See
55 Fed. Reg.
52402 (Dec. 21, 1990). This nullified the prior USDOT definition relied upon by USEPA and
rendered all the methods used under that rule obsolete.
The effect of the 1990 USDOT revisions on the USEPA hazardous waste rules was
significant, although it passed for a long time without apparent notice. The current USDOT
rules no longer included 49 C.F.R. 173.300 defining “flammable compressed gas.” Thus, the
reference in 40 C.F.R. 261.21(a)(3) to 49 C.F.R. 173.300 for definition of “ignitable compressed
gas” became meaningless, unless one inferred that USEPA intended to include a material in the
USDOT “flammable gas” hazard class as “ignitable waste.” Supporting this inference would
require reading the reference to “49 C.F.R. 173.300” as meaning “49 C.F.R. 173.115” after the
1990 USDOT amendments. This was the inference made by the Board when dealing with this
provision in 2006, as described below.
In 2005, the Board dealt with this problem and attempted to correct it in early 2006. The
Board amended corresponding 35 Ill. Adm. Code 721.121(a)(3) in UIC Corrections, USEPA
Amendments (January 1, 2005 through June 30, 2005), R06-5, RCRA Subtitle D Update,
USEPA Amendments (January 1, 2005 through June 30, 2005 and August 1, 2005), R06-6,
RCRA Subtitle C Update, USEPA Amendments (January 1, 2005 through June 30, 2005 and
August 1, 2005), R06-7 (Jan. 5, 2006) (consolidated). In Section 721.121(a)(3), the Board
changed the former USDOT term “ignitable compressed gas” to the current “flammable gas,” as
has been used by USDOT. The Board changed the obsolete reference for the definition from 49
C.F.R 173.300 to 49 C.F.R. 173.115. The Board then appended brief note to subsection (a)(3)
that explained the USDOT amendments, the lack of a USEPA response, and the Board’s
deviations from the text of the corresponding USEPA provisions.
USEPA itself corrected the obsolete references on July 14, 2006. Rather than referring to

33
the post-1990 USDOT hazard class for definition of “flammable gas,” in order to maintain
status
quo
, USEPA moved in the opposite direction. The intent of USEPA’s approach to the changes
in the USDOT rules was to initiate no change through the July 14, 2006 corrections. This is
apparent from the discussion of the corrections to paragraph (a)(3):
When EPA first promulgated the ignitability characteristic for hazardous
waste identification, the Agency incorporated, by reference, U.S. Department of
Transportation (DOT) regulations (contained in Title 49 of the CFR) that defined
an ignitable compressed gas and an oxidizer. In 1990, DOT revised and
recodified its regulations governing transportation of hazardous materials,
including the sections of 49 CFR referenced by 40 CFR 261.21. The referenced
DOT regulations were both revised and moved within 49 CFR; as a result, the
hazardous characteristic definitions at 40 CFR 261.21(a)(3) and 261.21(a)(4) now
refer to nonexistent or irrelevant sections of the DOT regulations.
Since these original DOT regulations are still required under RCRA, EPA
is replacing the obsolete references to the DOT regulations contained in the
definitions for an ignitable compressed gas and an oxidizer, 40 CFR 261.21(a)(3)
and 261.21(a)(4), respectively, with the actual language from the referenced
sections of the DOT regulations that was published in Title 49 of the CFR at the
time of the finalization of the RCRA regulations (1980). Because it can be
difficult to obtain copies of the CFR from 1980, this revision will make it easier
for the regulated community to find and apply the definitions of ignitable
compressed gas and oxidizer for the purposes of 261.21. The implementation and
enforcement of the ignitability characteristic will not change in any way. The
Agency is simply publishing the original definitions to ease the burden on the
regulated community. 71 Fed. Reg. 40254-55 (July 14, 2006);
see
55 Fed. Reg.
52402 (Dec. 21, 1990) (the cited USDOT amendments).
While USEPA clearly stated its intent not to alter the rule by the corrections, the Board
does not believe that USEPA’s corrections accomplished that purpose. Lifting the definition of
“flammable gas” from the 1980 edition of the
Code of Federal Regulations
does not give the
term the meaning that USEPA intended when adopting 40 C.F.R. 261.21(a)(3) in 1980. The
Board believes that the USEPA assertion, “The implementation and enforcement of the
ignitability characteristic will not change in any way” (
see
71 Fed. Reg. at 40255), is inaccurate.
USEPA’s July 14, 2006 corrections created problems. Some of the problems are minor
format errors. Others are more significant and relate to the wording and viability of the
definition. The Board believes that USEPA’s July 14, 2006 corrections to 40 C.F.R.
261.21(a)(3) make the definition of “ignitable waste” more difficult to implement that it was
before the corrections. An inferred intent to include post-1990 USDOT “flammable gas” as
“ignitable waste” is easier to implement than the borrowing of incorporation of the language of
the 1980 version of the USDOT definition into the hazardous waste regulations. Further,
USEPA’s July 14, 2006 corrections altered the text of the 1980 USDOT definition of
“flammable compressed gas” from 49 C.F.R. 173.300(a) and (b) when correcting the 40 C.F.R.
261.21(a)(3) definition of “ignitable compressed gas.” This could bolster an inference that

34
USEPA intended something different.
The corrected text of 40 C.F.R. 261.21(a)(3) now reads as follows (with the USEPA
changes to the USDOT definition indicated with underlining and overstrike):
§ 261.21 Characteristic of ignitability.
(a) A solid waste exhibits the characteristic of ignitability if a representative
sample of the waste has any of the following properties:
* * * * *
(3) It is an ignitable compressed gas.
(a) Compressed gas. (i) The term “compressed gas” shall designate any material
or mixture having in the container an absolute pressure exceeding 40 p.s.i. at 70°
F.70 °F or, regardless of the pressure at 70° F.70 °F, having an absolute pressure
exceeding 104 p.s.i. at 130° F.130 °F; or any liquid flammable material having a
vapor pressure exceeding 40 p.s.i. absolute at 100° F.100 °F as determined by
ASTM Test D–323.
(b) Flammable compressed gas. Any (ii) A compressed gas as defined in
paragraph (a) of this section shall be classed as “flammable gas” characterized as
ignitable if any one of the following occurs:
(1) (A) Either a mixture of 13 percent or less (by volume) with air forms a
flammable mixture or the flammable range with air is wider than 12 percent
regardless of the lower limit. These limits shall be determined at atmospheric
temperature and pressure. The method of sampling and test procedure shall be
acceptable to the Bureau of Explosives and approved by the Associate Director
for [the Office of Hazardous Materials Research] director, Pipeline and
Hazardous Materials Technology, U.S. Department of Transportation (see Note
2).
(2)
(B) Using the Bureau of Explosives’ Flame Projection Apparatus (see Note
1), the flame projects more than 18 inches beyond the ignition source with valve
opened fully, or, the flame flashes back and burns at the valve with any degree of
valve opening.
(3)
(C) Using the Bureau of Explosives’ Open Drum Apparatus (see Note 1),
there is any significant propagation of flame away from the ignition source.
(4)
(D) Using the Bureau of Explosives’ Closed Drum Apparatus (see Note 1),
there is any explosion of the vapor-air mixture in the drum.

Open Drum Apparatus, Closed Drum Apparatus, and method of tests may be

Note 2: As part of a U.S. Department of Transportation (DOT) reorganization,
the Office of Hazardous Materials Technology (OHMT), which was the office
listed in the 1980 publication of 49 CFR 173.300 for the purposes of approving
sampling and test procedures for a flammable gas, ceased operations on February
20, 2005. OHMT programs have moved to the Pipeline and Hazardous Materials
Safety Administration (PHMSA) in the DOT. 40 C.F.R. 261.21(a)(3) (2006), as
amended at 71 Fed. Reg. 40254, 40259 (July 14, 2006) compared with 49 C.F.R.
173.300(a) and (b) (1980) (changes indicated with underlining and overstrike).
The minor format errors in this language as easily corrected. The appropriate abbreviated
form for temperatures is to place the degree symbol “°” immediately after the numeric
temperature, followed by the Fahrenheit abbreviation “F” separated by a space. USEPA placed
the space between the numeric temperature and degree symbol, with no space before the
Fahrenheit abbreviation. Thus, USEPA should have rendered “70 °F” as ”70° F.” The Board
has corrected this in the Illinois rule. The appropriate way to abbreviate an absolute pressure in
pounds per square inch (p.s.i.) is to use the abbreviation “p.s.i.a.” or “psia.” If the Board adopts
amendments based directly on USEPA’s approach to correction of 40 C.F.R. 261.21(a)(3), the
Board will make the appropriate of these corrections.
More significant problems could create difficulties with implementation of a rule based
on obsolete USDOT text. Those problems may require the Board to deviate from the literal text
of 40 C.F.R. 261.21(a)(3), as corrected, in order to implement USEPA’s intent.
See
415 ILCS
5/7.2(a) (2006). As discussed above, the original shifting from USDOT’s designation
“flammable compressed gas” to “ignitable compressed gas” lead to ambiguity in what is
intended. The 1990 USDOT abandonment of the original designation served to increase the
potential for ambiguity as to what USDOT-designated materials are included in the definition.
The obsolescence of the methods used for making the determination makes the definition
unworkable. Implementation of USEPA’s apparent original intent of including as “ignitable
waste” those materials classed by USDOT as “flammable compressed gas” is difficult if not
impossible based on methods and approvals that USDOT has not itself used for nearly 20 years.
The Board has considered how to best deal with the defects in the USEPA incorporation
of the obsolete USDOT definitions into the hazardous waste regulations. There are several
options, ranging from making minimal changes to the federal text to taking a different approach
that might prove easier to implement and enforce in a way intended by USEPA. The Board
considers a few of those options in the following segment of this discussion. The Board
presently sees three options for dealing with the problem and will discuss each in turn, ranging
from the option of making only minimal changes to the July 14, 2006 text to substituting a
reference to current USDOT regulations in place of the obsolete language from former 49 C.F.R.
173.300(a) and (b). Such a reference currently exists in 35 Ill. Adm. Code 721.121(a)(3) in the
Illinois rules (corresponding with 40 C.F.R. 261.21(a)(3)).

36
It may be that implementation of the July 14, 2006 corrections requires the Board to take
the most dramatic departure from the literal USEPA language by substituting the old USDOT
language with the existing reference in Illinois rule to the current USDOT regulations. This is
the approach that the Board presented in the March 20, 2008 proposal for public comment, and
which the Board now adopts. The following discussion considers the various options for dealing
with the corrections to 40 C.F.R. 261.21(a)(3) in corresponding 35 Ill. Adm. Code 721.121(a)(3).
The 1980 USDOT definition of “flammable compressed gas” is from a context different
from that of the USEPA definition of “ignitable compressed gas.” In the USDOT rules,
compressed gas has independent meaning as a class of hazardous material distinct from
“flammable compressed gas.” The USDOT definitions of “compressed gas” and “flammable
compressed gas” are presented as coordinate definitions, with the definition of “flammable
compressed gas” following and partially dependent on the definition of “compressed gas.”
See
40 C.F.R. 173.300(a) and (b) (1980) (the obsolete USDOT definition relied on by USEPA);
see
also
40 C.F.R. 173.115(a) and (b) (2006) (the current USDOT definition). In the hazardous
waste regulations, the term “compressed gas” has no meaning in the hazardous waste
regulations; it exists only to support the definition of “ignitable compressed gas.”
See
40 C.F.R.
261.21(a)(3)(ii) (2006), as amended at 71 Fed. Reg. 40254, 40259 (July 14, 2006).
USEPA could have overcome the differences in context with minor changes in the
language, but the changes made by USEPA worked in the opposite way. Paragraph (a)(3)(i) now
defines “compressed gas,” and paragraph (a)(3)(ii) states when a compressed gas “is
characterized as ignitable.”
See
40 C.F.R. 261.21(a)(3) (2006), as corrected at 71 Fed. Reg.
40254, 40259 (July 14, 2006). Presenting the USDOT definition of “compressed gas” first as a
coordinate provision places more direct emphasis on the subsidiary definition of “compressed
gas.” Replacing the USDOT language that clearly defined “flammable compressed gas” with a
coordinate statement as to when it is “characterized as ignitable” is a further step away from a
direct definition of “ignitable compressed gas.” The USDOT language, as borrowed by USEPA,
nowhere directly defines “ignitable compressed gas,” as did the original language of the 1980
USDOT definition of “flammable compressed gas.” Compare 40 C.F.R. 261.21(a)(3)(ii) (2006),
as amended at 71 Fed. Reg. 40254, 40259 (July 14, 2006) with 49 C.F.R. 173.300(b) (1980).
Assuming that USEPA had to use the outdated 1980 USDOT definition of “flammable
compressed gas,” and that it had to use “ignitable” in place of USDOT’s use of “flammable,” the
Board believes that USEPA should have used one of two alternatives to clarify the definition.
The first alternative would have been for USEPA to more closely follow the original USDOT
language, in order to assure that the language directly defined the term “ignitable compressed
gas.” More closely following the 1980 USDOT language would have resulted in a definition
similar to the following (indicating the possible revisions to the corrected USEPA definition by
underlining and overstrike):
§ 261.21 Characteristic of ignitability.
(a) A solid waste exhibits the characteristic of ignitability if a representative
sample of the waste has any of the following properties:

37
* * * * *
(3) It is an ignitable compressed gas as defined in paragraph (a)(3)(ii) of this
section.
(i) The term “compressed gas” shall designate any material or mixture having in
the container an absolute a pressure exceeding 40 p.s.i. absolute (p.s.i.a.) at 70 °F
70° F or, regardless of the pressure at 70 °F 70° F, having an absolute a pressure
exceeding 104 p.s.i. at 130 °F 130° F; or any liquid flammable material having a
vapor pressure exceeding 40 p.s.i. absolute p.s.i.a. at 100 °F 100° F as determined
by ASTM Test D–323.
(ii) A compressed gas, as defined in paragraph (a)(3)(i) of this section, shall be
characterized classed as “ignitable compressed gas” if any one of the following
occurs (see Note 2):
(A) Either a mixture of 13 percent or less (by volume) with air forms a
flammable mixture or the flammable range with air is wider than 12 percent
regardless of the lower limit. These limits shall be determined at atmospheric
temperature and pressure. The method of sampling and test procedure shall be
acceptable to the Bureau of Explosives and approved by the director, Pipeline and
Hazardous Materials Technology, U.S. Department of Transportation (see Note
2).
(B) Using the Bureau of Explosives’ Flame Projection Apparatus (see Note 1),
the flame projects more than 18 inches beyond the ignition source with valve
opened fully, or, the flame flashes back and burns at the valve with any degree of
valve opening.
(C) Using the Bureau of Explosives’ Open Drum Apparatus (see Note 1), there is
any significant propagation of flame away from the ignition source.
(D) Using the Bureau of Explosives’ Closed Drum Apparatus (see Note 1), there
is any explosion of the vapor-air mixture in the drum.

Note 2: As part of a U.S. Department of Transportation (DOT) reorganization,
the Office of Hazardous Materials Technology (OHMT), which was the office
listed EPA has defined “ignitable compressed gas” based on the U.S. Department
of Transportation definition of “flammable compressed gas” set forth in the 1980

38
publication version of 49 CFR 173.300 for the purposes of approving sampling
and test procedures for a flammable gas, ceased operations on February 20, 2005.
OHMT programs have moved to the Pipeline and Hazardous Materials Safety
Administration (PHMSA) in the DOT. The U.S. Department of Transportation
moved its definition of “flammable gas” to 49 CFR 173.115 and amended it in
1990 (at 55 FR 52634, Dec. 21, 1990). EPA continues to rely on the U.S.
Department of Transportation definition from the 1980 version of 49 CFR
173.300 and has adapted the language of that definition into this paragraph (a)(3).
A second, more preferable alternative would have been for USEPA to revise the structure
of the definition to more pointedly define “ignitable compressed gas.” Such a revised structure
could chiefly have involved changing the relative positions of paragraphs (a)(3)(i) and (a)(3)(ii)
and minimally revising the language of both, in order to place the greater emphasis on the
definition of “ignitable compressed gas” and clarify the subordinate role of the definition of
“compressed gas.” Such a restructured definition could have appeared as follows (indicating the
Board-suggested clarifications of the USEPA language by underlining and overstrike):
§ 261.21 Characteristic of ignitability.
(a) A solid waste exhibits the characteristic of ignitability if a representative
sample of the waste has any of the following properties:
* * * * *
(3) It is an ignitable compressed gas as defined in this paragraph.
(ii) (i) A An “ignitable compressed gas” means a compressed gas, as defined in
paragraph (a)(3)(ii) of this section, shall be characterized as ignitable if of which
any one of the following occurs is true (see Note 2):
(A) Either a mixture of 13 percent or less (by volume) with air forms a
flammable mixture,
or the flammable range with air is wider than 12 percent
regardless of the lower limit. These limits shall be determined at atmospheric
temperature and pressure. The method of sampling and test procedure shall be
acceptable to the Bureau of Explosives and approved by the director, Pipeline and
Hazardous Materials Technology, U.S. Department of Transportation (see Note
2).;
(B) Using the Bureau of Explosives’ Flame Projection Apparatus (see Note 1),
the flame projects more than 18 inches beyond the ignition source with valve
opened fully, or, the flame flashes back and burns at the valve with any degree of
valve opening.;
(C) Using the Bureau of Explosives’ Open Drum Apparatus (see Note 1), there is
any significant propagation of flame away from the ignition source; or

39
(D) Using the Bureau of Explosives’ Closed Drum Apparatus (see Note 1), there
is any explosion of the vapor-air mixture in the drum.
(i)(ii) The term “compressed gas” shall designate means any material or mixture
having in the container an absolute a pressure exceeding 40 p.s.i. absolute
(p.s.i.a.) at 70 °F 70° F or, regardless of the pressure at 70 °F 70° F, having an
absolute a pressure exceeding 104 p.s.i.a. at 130 °F 130° F; or any liquid
flammable material having a vapor pressure exceeding 40 p.s.i.a. absolute at 100
°F 100° F, as determined by ASTM Test Method D–323.

Note 2: As part of a U.S. Department of Transportation (DOT) reorganization,
the Office of Hazardous Materials Technology (OHMT), which was the office
listed EPA has defined “ignitable compressed gas” based on the U.S. Department
of Transportation definition of “flammable compressed gas” set forth in the 1980
publication version of 49 CFR 173.300 for the purposes of approving sampling
and test procedures for a flammable gas, ceased operations on February 20, 2005.
OHMT programs have moved to the Pipeline and Hazardous Materials Safety
Administration (PHMSA) in the DOT. The U.S. Department of Transportation
moved its definition of “flammable gas” to 49 CFR 173.115 and amended it in
1990 (at 55 FR 52634, Dec. 21, 1990). EPA continues to rely on the U.S.
Department of Transportation definition from the 1980 version of 49 CFR
173.300 and has adapted the language of that definition into this paragraph (a)(3).
While either of these two alternatives would have added clarity to the definition of
ignitable waste, the Board does not find either alternative very appealing. The use of the old,
borrowed USDOT definition of “flammable compressed gas” presents other, more significant
problems relate to the methods for testing flammability or ignitability. Neither of the two
options above deals with the most significant problems with the text.
The problems arising through the methods used for testing whether a material is ignitable
are the most significant. In 40 C.F.R. 261.21(a)(3)(ii)(A) (corresponding with 35 Ill. Adm. Code
721.121(a)(3)(A)(i)), the testing uses a procedure “acceptable to the Bureau of Explosives and
approved by the director, Pipeline and Hazardous Materials Technology, U.S. Department or
Transportation.” This references no distinct methods. The Administrative Procedure Act
requires reference to an existing document.
See
5 ILCS 100/5-75 (2006). The Board cannot
recite nothing as a method for determination, and the Board cannot incorporate nothing as a
method by reference.
In 40 C.F.R. 261.21(a)(3)(ii)(B) through (a)(3)(ii)(D) (corresponding with 35 Ill. Adm.
Code 721.121(a)(3)(A)(ii) through (a)(3)(A)(iv)), there is a similar problem. The federal rule

40
refers to the “Bureau of Explosives’ Flame Projection Apparatus,” the “Bureau of Explosives’
Open Drum Apparatus,” and the “Bureau of Explosives’ Closed Drum Apparatus,” none of
which is defined. An Internet search has led the Board to an undated document entitled,
“Aerosol Flame Projection Tests,” which is available for download from the Association of
American Railroads, Bureau of Explosives, Operations and Maintenance Department (from
Internet address http://boe.aar.com/boe-download.htm). The Board could not determine a date
for the reference, but the document dates back to at least the 1964 republication of 49 C.F.R.
73.300 (the forerunner to 49 C.F.R. 173.300).
See
29 Fed. Reg. 18652, 18743 (Dec. 29, 1964)
(republication of 49 C.F.R. 173 to embrace a series of earlier amendments). The Board cannot
incorporate the old Bureau of Explosives method by reference, since the Administrative
Procedure Act requires use of a dated document for incorporation by reference.
See
5 ILCS
100/5-75 (2006).
The Board cannot incorporate the methods recited in corrected 40 C.F.R. 261.21(a)(3) by
reference.
See
5 ILCS 100/5-75 (2006). The Board cannot recite nothing as a method for
determination or incorporate an unidentified or undated document as a method by reference. The
Administrative Procedure Act requires reference to an existing, dated document. Thus, the
Board cannot incorporate the unidentified methods approved by USDOT or the old identified,
undated Bureau of Explosives methods by reference, since the Administrative Procedure Act
(APA) requires use of a dated document for incorporation by reference.
See
5 ILCS 100/5-75
(2006).
One option for resolving these issues would be for the Board to simply incorporate 40
C.F.R. 261.21(a)(3) by reference. The Board could amend corresponding 35 Ill. Adm. Code
721.121(a)(3) to read as follows:
§ 261.21 Characteristic of ignitability.
(a) A solid waste exhibits the characteristic of ignitability if a representative
sample of the waste has any of the following properties:
* * *
(3) It is an “ignitable compressed gas” as defined in 40 CFR 261.21(a)(3),
incorporated by reference in 35 Ill. Adm. Code 720.111(b).
This solution, however, has only a superficial appeal. While it is a legitimate incorporation by
reference under the APA, it does not resolve the issues and provide methods for determining
what materials are “ignitable compressed gas.”
Another possible solution exists for the Board to overcome the problems with
incorporation of the undated Bureau of Explosives methods by reference. This would involve
setting forth the verbatim text of the Bureau of Explosives methods in an appendix to 35 Ill.
Adm. Code 721. For the sake of public comment, the Board has reproduced the verbatim text of
the Bureau of Explosives document that embodies the methods. The reference is not so freely
available as to allow the Board to cite it with any confidence that interested persons can readily

41
locate its text.. If public comments justify the Board doing so, the Board may add the text of
those methods as an appendix to part 721. The Board duplicates the methods text in this
opinion, as follows:
AEROSOL FLAME PROJECTION TESTS
Section 173.300(b) subparagraphs (2), (3), and (4) of Title 49 to the Code
of Federal Regulations referenced the Bureau of Explosives’ Flame Projection
Apparatus, Open Drum Apparatus and Closed Drum Apparatus to be used when
examining aerosol products.
The following are descriptions or the equipment and testing procedures to
be used when conducting the tests. Any further questions relating to this testing
should be addressed to the Director at the above address.
FLAME PROJECTION TEST
Equipment
- The test equipment consists of a base four inches wide and
two feet long, A thirty inch rule (with inches marked) is supported horizontally
on the side of the base and about six inches above it. A plumber’s candle of such
height that the top third of the flame is at the height of the horizontal rule is
placed at the zero point in the base.
Procedure
- The test is conducted in a draft-free area that can be
ventilated and the atmosphere cleared between each test. The self-pressurized
container is placed at a distance of six inches from the ignition source and the
spray jetted into the top third of the flame with valve opened fully for periods or
15-20 seconds. The length of the flame projection from the candle position is
read on the horizontal scale. Three or more readings are taken on each sample
and average is taken as the result. Samples are also tested with valve in partially
open positions to test for “burning back” to valve.
DRUM TESTS
Equipment
- The equipment consists of a 55-gallon open-headed steel
drum or similar container whish is placed on its side and fitted with a hinged
cover over the open end that will open at a pressure of 5 p.s.i. The closed or solid
end is equipped with one shuttered opening at the top. This is for the introduction
of the spray. The opening is approximately two inches from the edge of drum
head and is two inches in diameter. There is a safety glass or plastic window six
inches square in the center of the solid end. A lighted plumber’s candle is placed
inside the drum on the lower side and midway between the ends.
Procedure
- The test is conducted in the open and when temperature is
between 60° F and 80° F.

42
OPEN DRUM TESTS
The test is conducted with hinged end in a completely open position and
with the shutter closed. The spray from the dispenser, with opened fully, is
directed in the upper half of the open end and above the ignition source for one
minute. Any significant propagation of flame through the vapor-air mixture away
from the ignition source shall be considered a positive result -- but -- any minor
and unsustained burning in the immediate area of the ignition source shall not be
considered a positive result.
CLOSED DRUM TESTS
The test is conducted with hinged cover dropped into position to rest
freely against the end and to close the open end of the drum to make a reasonably
secure but not necessarily a completely air-tight seal. The shutter is opened and
the spray is jetted into the drum through this shutter with valve fully opened for
one minute. After clearing the atmosphere in the drum, the jetting is repeated
similarly three times. Any explosion or rapid burning of the vapor-air mixture
sufficient to cause the hinged cover to move is considered a positive result.

The Board would prefer not to reproduce this text as an appendix to the Illinois rules.
Repeating the text would not resolve a fundamental problem with the age of the long-outmoded
method and the obsolete status of the USDOT definition of “flammable compressed gas.”
Further, it would not resolve the issues relating to the unidentified methods that were approved
by USDOT. The Board must look elsewhere to find those methods.
In 1990, USDOT changed “flammable compressed gas” to “flammable gas,” and it
changed the Bureau of Explosives methods to American Society for Testing and Materials
(ASTM) Method E 681-85, “Standard Test Method for Concentration Limits of Flammability of
Chemicals (Vapors and Gases).” Thus, in two regards, what USEPA intended as one aspect
“ignitable waste” shifted. What was once defined under USDOT regulations as “flammable
compressed gas” became known as “flammable gas,” and the method used to determine
flammability was updated by USDOT. The method approved by the “director, Pipeline and
Hazardous Materials Technology, U.S. Department of Transportation,” as contemplated in the
1980 version of 49 C.F.R. 173.300 and echoed in the newly corrected USEPA definition at 40
C.F.R. 261.21(a)(3)(ii)(A), changed from an obsolete, undated method to a distinct ASTM
method. Recitation of obsolete Bureau of Explosives methods is internally inconsistent 17 years
after USDOT abandoned use of that method.
Since the 1990 USDOT amendments, the definition of “flammable gas” has read as
follows:

43
§ 173.115 Class 2, Divisions 2.1, 2.2, and 2.3—Definitions.
(a)
Division 2.1 (Flammable gas).
For the purpose of this subchapter, a
flammable gas
(Division 2.1) means any material which is a gas at 20 °C (68 °F)
or less and 101.3 kPa (14.7 psia) of pressure (a material which has a boiling point
of 20 °C (68 °F) or less at 101.3 kPa (14.7 psia)) which—
(1) Is ignitable at 101.3 kPa (14.7 psia) when in a mixture of 13 percent or less
by volume with air; or
(2) Has a flammable range at 101.3 kPa (14.7 psia) with air of at least 12 percent
regardless of the lower limit. Except for aerosols, the limits specified in
paragraphs (a)(1) and (a)(2) of this section shall be determined at 101.3 kPa (14.7
psia) of pressure and a temperature of 20 °C (68 °F) in accordance with the
ASTM E681–85, Standard Test Method for Concentration Limits of Flammability
of Chemicals or other equivalent method approved by the Associate
Administrator. The flammability of aerosols is determined by the tests specified
in § 173.115 (k) of this section. 49 C.F.R. 173.115(a) (2006).
USDOT stated that its 1990 shift from the 1980 49 C.F.R. 173.300 definition of
“flammable compressed gas” to the newer 49 C.F.R. 173.115 definition of “flammable gas” did
not intend to change the meaning or scope of the test for flammability. USDOT stated as
follows:
Paragraph (a) defines Division 2.1 (flammable gasses) as: (1) A gas under
ambient conditions (i.e., 101.3 kPa (14.7 psia) and 20 °F (68 °F)) [sic], and (2)
flammable. The flammability criteria referring to flammability limits come from
existing regulations (§ 173.300(b)(1)). The test methods listed in paragraphs
(b)(2), (b)(3), and (b)(4) of § 173.300 have been replaced by ASTM E681-85
Standard Test Method for Limits of Flammability of Chemicals. 55 Fed. Reg.
52402, 53433 (Dec. 21, 1990).
The test methods formerly listed in 49 C.F.R. 173.300(b)(2), (b)(3), and (b)(4) that USDOT
replaced with an ASTM method were the obsolete Bureau of Explosives methods discussed
above.
If USDOT did not change the flammability criteria, the question becomes whether
USDOT changed any other aspects of the definition. As it turns out, USDOT did change the
definition in two small ways that the Board does not believe are significant for the purpose of 40
C.F.R. 261.21(a)(3).
First, the 1990 definition changed “70° F,” which appeared in the 1980 definition, to “20
°C (68 °F) [sic].” This is a shift from approximate standard room temperature in Fahrenheit to
approximate standard room temperature in Celsius: a change of 2° F. The Board does not
believe that this is a difference, as one would be hard-put to find a material that is a gas at 70° F
that is not also a gas at 68° F.

44
Second, USDOT removed the requirement that the material be “compressed gas” to be
designated “flammable gas.” This is the real difference between a “flammable compressed gas”
under the 1980 definition in 49 C.F.R. 173.300(b) and a “flammable gas” under the current
USDOT definition in 49 C.F.R. 173.115(a) is the “compressed” aspect of the gas. The 1980
USDOT hazard class “flammable compressed gas” required that the material have a pressure in
the container of 40 p.s.i.a. at 70° F or 104 p.s.i.a. at 130° F, or a vapor pressure of 40 p.s.i.a. at
100° F if it is a liquid flammable material. The USDOT hazard class “flammable gas” in use
since 1990 does not require pressures elevated above ambient. The Board questions, however,
whether even this is a distinction with a difference. The universe of containerized gas or high-
vapor pressure liquid materials that are a gas at standard room temperature and pressure (101.3
kPa at 20° C) and which do not have a pressure in the container that would fulfill the pressure
requirements of the 1980 USDOT definition is likely small. Moreover, dropping the pressure
requirement of the 1980 definition in favor of standard room temperature and pressure as used in
the 1990 definition would include, rather than exclude that small universe of materials from the
definition of “ignitable waste,” as defined in 40 C.F.R. 261.21(a)(3).
In summary, the Board believes that 40 C.F.R. 261.21(a)(3) is meaningless as corrected
by USEPA on July 14, 2006. The use of the obsolete USDOT designation “flammable
compressed gas” from the 1980 version of 49 C.F.R. 173.300(b) and continued reliance on
obsolete Bureau of Explosives methods for sampling and testing gives rise to a meaningless
provision. USEPA originally intended to include materials in the USDOT hazard class as
ignitable waste. The USDOT re-designated the hazard class in 1990 to “flammable gas” in 49
C.F.R. 173.115(a), but USEPA did not respond to that shift for several years. In the time that
passed since 1980, the former USDOT hazard class became meaningless. Reviving that obsolete
USDOT hazard class, as now contemplated by USEPA, is futile, as the Bureau of Explosives
methods have become so grossly out of date that there is no longer any reference to them in the
USDOT regulations.
See
49 C.F.R. 173 (2007). USEPA should instead have changed 40 C.F.R.
261.21(a)(3) to include the current USDOT hazard class “flammable gas,” and it should have
referred to 49 C.F.R. 173.115(a) for definition of that term.
Since USEPA did not, the Board is then confronted with several options. The Board
outlines those options as follows:
1.
The Board could simply repeat the 1980 USDOT definition of “flammable
compressed gas,” re-designated as “ignitable compressed gas,” as set forth by
USEPA in its July 14, 2006 corrections, with or without minor revisions to
enhance its clarity and make it follow the original USDOT definition more
closely.
2.
The Board could repeat the 1980 USDOT definition of “flammable compressed
gas,” re-designated as “ignitable compressed gas,” restructuring how USEPA
presented it in its July 14, 2006 corrections, in order to enhance its clarity.
3.
The Board could repeat the 1980 USDOT definition of “flammable compressed
gas,” re-designated as “ignitable compressed gas,” restructuring how USEPA

45
presented it in its July 14, 2006 corrections, in order to enhance its clarity, and
substituting ASTM Method E 681 for the obsolete Bureau of Explosives methods.
4.
The Board could replace “ignitable compressed gas,” derived from the old
USDOT rule and dependent on obsolete and meaningless sampling and testing
methods, as included by USEPA in its July 14, 2006 corrections, with “flammable
gas,” as defined by the current USDOT regulation and determined using ASTM
Method E 681.
The Board prefers the final option in this list. Although it embodies the greatest
departure from the literal text of 40 C.F.R. 261.21(a)(3), as corrected, it would involve the least
amendment to corresponding 35 Ill. Adm. Code 721.121(a)(3) as it presently exists. As
discussed above, the Board corrected the text of 35 Ill. Adm. Code 721.121(a)(3)to incorporate
the current USDOT definition of “flammable gas,” in the consolidated docket UIC Corrections,
USEPA Amendments (January 1, 2005 through June 30, 2005), R06-5, RCRA Subtitle D
Update, USEPA Amendments (January 1, 2005 through June 30, 2005 and August 1, 2005),
R06-6, RCRA Subtitle C Update, USEPA Amendments (January 1, 2005 through June 30, 2005
and August 1, 2005), R06-7 (cons.) (Jan. 5, 2006). While a change in the scope of the definition
from that of the corresponding corrected USEPA provision at 40 C.F.R. 261.21(a)(3) may result,
the Board believes that any change would actually, at most, make the Illinois provision
marginally more inclusive. Thus, any change would not render the Illinois rules impermissibly
less stringent than corresponding 40 C.F.R. 261.21(a)(3).
See
42 U.S.C. § 6929 (2005).
Employing the first three options, each based on the corrected USEPA provision, would
require more extensive revision to the existing text of 35 Ill. Adm. Code 721.121(a)(3). The
third option of using some version of the 1980 USDOT definition of “flammable compressed
gas” while substituting ASTM Method E 681 for the Bureau of Explosives methods would
require incorporation of that method by reference. The first and second methods would require
incorporation of the undated, obsolete Bureau of Explosives methods by reference or including
their text in a new appendix to Part 721. The Board would prefer neither of these first two
alternatives.
The Board used this fourth option in the March 20, 2008 proposal for public comment,
and the adopted amendments retain this option. The Board has chosen to depart from the text
from the July 14, 2006 USEPA corrections. The Board has chosen to incorporate the current
USDOT definition of “flammable gas” from 49 C.F.R. 173.115(a) into the Illinois regulations at
35 Ill. Adm. Code 721.121(a)(3), rather than some version of the definition of “flammable
compressed gas” as it existed in 1980. The Board believes that this approach more closely
implements USEPA’s intent to include materials that fall within the USDOT hazard class as
ignitable waste.
The Board has further changed the content of USEPA-designated “Note 2” to explain the
use of the obsolete USDOT definition of “flammable compressed gas,” noting the location of the
current definition of “flammable gas.” The amendments adopted today reflect these revisions.

46
Corrections to 40 C.F.R. 261.21(a)(4) (corresponding with Section 721.121(a)(4))
Similarly to 40 C.F.R. 261.21(a)(3), 40 C.F.R. 261.21(a)(4) defines one class of materials
that exhibit the characteristic of ignitability. Federal paragraph (a)(4) designates any waste that
is an “oxidizer” as “ignitable waste.” As for the paragraph (a)(3) definition of “ignitable
compressed gas,” additional consideration is necessary for the July 14, 2006 corrections to 40
C.F.R. 261.21(a)(4) definition of “oxidizer.” The federal corrections to this provision also
present problems that the Board must resolve.
When USEPA adopted 40 C.F.R. 261.21(a)(4) in 1980, it defined “oxidizer” by reference
to the USDOT regulations. 40 C.F.R. 261.21(a)(4) (1980);
see
45 Fed. Reg. 33084, 33121-22
(May 19, 1980). The 1980 USEPA rule designated an “oxidizer” as “ignitable waste” by
reference to the USDOT definition of the term, as indicated in the text of 40 C.F.R. 261.21(a)(4).
This former paragraph defined what is an “oxidizer” by reference to USDOT regulations, as
follows:
§ 261.21 Characteristic of ignitability.
(a) A solid waste exhibits the characteristic of ignitability if a representative
sample of the waste has any of the following properties:
* * *
(4) It is an oxidizer as defined in 49 CFR 173.151. 40 C.F.R. 261.21(a)(4) (2006).
The USDOT definition relied upon was 49 C.F.R. 173.151 (1980), which defined the “oxidizer”
hazard class as follows:
§ 173.151 Oxidizer; definition.
An oxidizer for the purposed of this subchapter is a substance such as a chlorate,
permanganate, inorganic peroxide, or a nitrate, that yields oxygen readily to
stimulate the combustion of organic matter. 49 C.F.R. 173.151 (1980).
In 1990, USDOT changed the hazard class designations for “oxidizer” and “organic
peroxide.” USDOT moved the definition of “oxidizer” from 49 C.F.R. 173.151 to 49 C.F.R.
173.127(a). Thus, the USEPA citation in 40 C.F.R. 261.21(a)(4) to USDOT definition at 49
C.F.R. 173.151 became meaningless. The following new provision at 49 C.F.R. 173.127(a)
defined the “oxidizer” hazard class:
§ 173.127 Class 5, Division 5.1—Definition and assignment of packaging groups.
(a)
Definition.
For the purpose of this subchapter,
oxidizer
(Division 5.1) means a
material that may, generally by yielding oxygen, cause or enhance the combustion
of other materials.

47
(1) A solid material is classed as a Division 5.1 material if, when tested in
accordance with the UN Manual of Tests and Criteria (IBR, see § 171.7 of this
subchapter), its mean burning time is less than or equal to the burning time of a
3:7 potassium bromate/cellulose mixture.
(2) A liquid material is classed as a Division 5.1 material if, when tested in
accordance with the UN Manual of Tests and Criteria, it spontaneously ignites or
its mean time for a pressure rise from 690 kPa to 2070 kPa gauge is less then the
time of a 1:1 nitric acid (65 percent)/cellulose mixture. 49 C.F.R. 173.127(a)
(2006).
The Board dealt with the 1990 USDOT amendments that replaced former 49 C.F.R.
173.151 with new 49 C.F.R. 173.127, in UIC Corrections, USEPA Amendments (January 1,
2005 through June 30, 2005), R06-5, RCRA Subtitle D Update, USEPA Amendments

(cons.) (Jan. 5, 2006). In Section 721.121(a)(4), the Board changed the obsolete reference for
the definition of “oxidizer” from 49 C.F.R. 173.151 to 49 C.F.R. 173.127. The Board further
appended a brief note to subsection (a)(4) that explained the USDOT amendments, the lack of a
USEPA response, and the Board’s deviations from the text of the corresponding USEPA
provisions.
USEPA itself corrected the obsolete reference to the former USDOT definition of
“oxidizer” on July 14, 2006. USEPA concurrently described the nature of its corrections to
paragraphs (a)(3) and (a)(4) in the preamble to the July 14, 2006 corrections. (A segment of that
explanation appears above, on page 31 of this opinion.) USEPA stated that it intended no
change in the scope of its rules when it incorporated the text of the 1980 USDOT definition from
49 C.F.R. 173.151 into 40 C.F.R. 261.21(a)(4).
See
71 Fed. Reg. 40254-55 (July 14, 2006). The
Board does not believe that the July 14, 2006 corrections achieved USEPA’s intent.
As it did with 40 C.F.R. 261.21(a)(3) for a definition of “ignitable compressed gas,”
USEPA has relied on language from an obsolete 1980 USDOT provision for the corrected
definition of “oxidizer” in 40 C.F.R. 261.21(a)(4). USEPA ignored more recent definition of
“oxidizer” that has been a part of the USDOT regulations as 49 C.F.R. 173.127 since 1990.
USEPA instead chose to use the obsolete 1980 USDOT definition to avoid changing the scope of
the definition of “oxidizer” as used in the hazardous waste regulations. The Board has therefore
encountered similar problems with the text of 40 C.F.R. 261.21(a)(4) to those encountered with
that of 40 C.F.R. 261.21(a)(3).
The initial problem arises through the obsolete USDOT definition that is the core of the
USEPA definition. While it states that an oxidizer “is a material that . . . yields oxygen readily
to stimulate combustion of organic matter,” and it gives the examples of “chlorate,
permanganate, inorganic peroxide, or a nitrate” (49 C.F.R. 173.151 (1980) (cited above)), the
definition lacks in definiteness. There are no methods cited for determining how readily the
material must yield oxygen, to what extent and under what conditions it must support
combustion, and the type of organic matter whose combustion it must support. Contrast this

48
against the current USDOT definition, which cites the methods of a specific document and the
threshold criteria for the determination of whether the material is an oxidizer.
See
49 C.F.R.
173.127(a) (2006) (cited at page 47 above).
9
This lack of definiteness in the obsolete USDOT
definition of “oxidizer” would favor citation instead to the current USDOT definition.
10
Another serious problem exists in the USEPA definition of “oxidizer” as corrected on
July 14, 2006. The 1980 version of the USDOT regulations included a separate definition of
“organic peroxide” at 49 C.F.R. 173.151a, which was a similar type of material, but a distinct
hazard class. The 1980 USDOT rules defined “organic peroxide” as follows:
§ 173.151a Organic peroxide; definition.
(a) An organic compound containing the bivalent -O-O- structure and which may
be considered a derivative or hydrogen peroxide where one or more or the
hydrogen atoms have been replaced by organic radicals must be classed as an
organic peroxide unless:
(1) The material meets the definition of an explosive A or explosive B, as
described in Subpart C of this part, in which case it must be classed as an
explosive,
(2) The material is forbidden to be offered for transportation according to
§ 172.101 or § 173.21 of this subchapter,
(3) It is determined that the predominant hazard of the material containing an
organic peroxide is other than that of an organic peroxide, or
(4) According to data on file with the Materials Transportation Bureau, is has
9
The newer USDOT Division 5.1 hazard class defines an oxidizer as “a material that may,
generally by yielding oxygen, cause or enhance the combustion of other materials.” 49 C.F.R.
173.127(a) (2006). The newer definition directs attention to methods in
UN Recommendations
on the Transport of Dangerous Goods, Manual of Tests and Criteria
(4th rev. ed., 2003),
available from the United Nations Economic Commission for Europe (UNECE), Transport
Division, for determination of whether a material falls within the definition.
See
49 C.F.R.
173.7(a)(3) and 173.127(a)(1) and (a)(2) (2006).
10
This may have presented less of a problem in the USDOT regulations than it would in the
current USEPA hazardous waste regulations because the USDOT regulations included the
“Hazardous Materials Table” of 49 C.F.R. 172.101, which set forth the hazard class into which
the more common hazardous materials fell. 49 C.F.R. 172.101 (1980);
see also
49 C.F.R.
172.101 (2006). Even under the original USEPA definition of “oxidizer,” it is likely that the
regulated community referred to 49 C.F.R. 173.151(1980) would have relied on the Hazardous
Materials Table to determine whether a material was a USDOT oxidizer.

49
been determined that the material does not present a hazard in transportation. 49
C.F.R. 173.151a (1980).
USEPA not only incorporated the 1980 version of the definition of “oxidizer,” but it also
included the 1980 definition of “organic peroxide” as part of the definition. The July 14, 2006
USEPA corrections combined the definition of “oxidizer” from former 49 C.F.R. 173.151 with
the definition of “organic peroxide” from 49 C.F.R. 173.151a. The corrections changed 40
C.F.R. 261.21(a)(4) to read as follows:
§ 261.21 Characteristic of ignitability.
(a) A solid waste exhibits the characteristic of ignitability if a representative
sample of the waste has any of the following properties:
* * *
(4) It is an oxidizer. An oxidizer for the purpose of this subchapter is a substance
such as a chlorate, permanganate, inorganic peroxide, or a nitrate, that yields
oxygen readily to stimulate the combustion of organic matter (see Note 4).
(i) An organic compound containing the bivalent -O-O- structure and which may
be considered a derivative of hydrogen peroxide where one or more of the
hydrogen atoms have been replaced by organic radicals must be classed as an
organic peroxide unless:
(A) The material meets the definition of a Class A explosive or a Class B
explosive, as defined in § 261.23(a)(8), in which case it must be classed as an
explosive,
(B) The material is forbidden to be offered for transportation according to 49
CFR 172.101 and 49 CFR 173.21,
(C) It is determined that the predominant hazard of the material containing an
organic peroxide is other than that of an organic peroxide, or
(D) According to data on file with the Pipeline and Hazardous Materials Safety
Administration in the U.S. Department of Transportation (see Note 3), it has been
determined that the material does not present a hazard in transportation.
* * * * *
Note 3: As part of a U.S. Department of Transportation (DOT) reorganization, the
Research and Special Programs Administration (RSPA), which was the office listed in
the 1980 publication of 49 CFR 173.151a for the purposes of determining that a material
does not present a hazard in transport, ceased operations on February 20, 2005. RSPA
programs have moved to the Pipeline and Hazardous Materials Safety Administration

50
(PHMSA) in the DOT.
Note 4: The DOT regulatory definition of an oxidizer was contained in § 173.151
of 49 CFR, and the definition of an organic peroxide was contained in paragraph
173.151a. An organic peroxide is a type of oxidizer. 40 C.F.R. 261.21(a)(4)
(2006), as amended at 71 Fed. Reg. 40254 (July 14, 2006).
Neither the text of former 40 C.F.R. 261.21(a)(3) nor the definition of “oxidizer” in
former 49 C.F.R. 173.151 would have included an “organic peroxide” as an “oxidizer,” so
inclusion of a definition for this material in the corrected text of 40 C.F.R. 261.21(a)(3) is not
justified if no expansion of the definition of “oxidizer” is intended. In the 1980 USDOT rules
drawn on by USEPA, 49 C.F.R. 173.151a was never subsidiary to 49 C.F.R. 173.151. The 1980
version of 49 C.F.R. 173.151 did not include “organic peroxide.” Further, the definition of
“oxidizer” has always had the categorical inclusion of “inorganic peroxide.” It has never
categorically included either “peroxide” generally or “organic peroxide” categorically. This
would implicitly exclude the possibility of categorical inclusion of organic peroxide material.
Thus, it would appear that the previous 40 C.F.R. 261.21(a)(4) reference to “oxidizer as defined
in 49 CFR 173.151” from the 1980 version of the USEPA rules did not include “organic
peroxide.”
Nevertheless, the July 14, 2006 USEPA corrections to 40 C.F.R. 261.21(a)(3) included
organic peroxide as an “oxidizer.” Thus, the text that USEPA added to 40 C.F.R. 261.21(a) with
the July 14, 2006 corrections and designated as “note 4” actually altered the scope of the
definition of “oxidizer.”
The effect of the July 14, 2006 corrections, therefore, was to broaden the definition of
“oxidizer” to include “organic peroxide.” This was contrary to USEPA’s stated intent not to
change the scope of the existing rule by its July 14, 2006 corrections to paragraph. As quoted
more fully above at page 31 of this discussion, USEPA said that no change in scope was
intended by the corrections:
Since these original [1980] DOT regulations are still required under
RCRA, EPA is replacing the obsolete references to the DOT regulations
contained in the definitions for . . . an oxidizer . . . with the actual language from
the referenced sections of the DOT regulations that was published in Title 49 of
the CFR at the time of the finalization of the RCRA regulations (1980). * * *
The implementation and enforcement of the ignitability characteristic will not
change in any way. The Agency is simply publishing the original definitions to
ease the burden on the regulated community. 71 Fed. Reg. 40254-55 (July 14,
2006);
see
55 Fed. Reg. 52402 (Dec. 21, 1990) (the cited USDOT amendments).
When lifting the definition of “oxidizer” from the 1980 edition of the
Code of Federal
Regulations
USEPA did not give the term “oxidizer” the same meaning it did when it initially
adopted 40 C.F.R. 261.21(a)(4) in 1980. The addition of the former USDOT definition of
“organic peroxide” to the definition of “oxidizer” has resulted in a major substantive alteration of
the rule. USEPA’s assertion in “note 4” appended to 40 C.F.R. 261.21(a) that organic peroxide

51
is a type of oxidizer was not true before USEPA made the assertion. Rather, the addition of the
language from the former USDOT definition of “organic peroxide” from 49 C.F.R. 173.151a and
the assertion in “note 4” that an organic peroxide is a type of oxidizer have made it true. The
additions expanded the definition of “oxidizer” to include organic peroxide. These revisions that
included organic peroxide as “oxidizer” are made despite USEPA’s clear statement of its intent
not to alter the scope of the rule by the corrections.
Some, but not all, organic peroxides are chemically oxidizers. An organic peroxide could
yield oxygen to support combustion of organic or other materials, as indicated in the 1980
USDOT definition of “oxidizer” that is now codified by USEPA in 40 C.F.R. 261.21(a)(4)(i), but
many organic peroxides are so extremely vigorous in doing so that they are far too hazardous to
classify as “oxidizers”; those organic peroxides would vigorously engage in self-combustion and
are more appropriately considered as “explosive” or “reactive” materials. This is evident from
the exclusions now incorporated into the corrected USEPA definition of “oxidizer” in 40 C.F.R.
261.21(a)(4)(i)(A) through (a)(4)(i)(C), which exclude explosive or highly reactive materials
from the definition.
Interestingly, this is reflected in both the USEPA and USDOT regulations. The organic
peroxides listed by USEPA as hazardous waste in 40 C.F.R. 261 are listed for toxicity and
reactivity, not for ignitability. The list of commercial chemical products and chemical
intermediates in 40 C.F.R. 261.33(f) includes three organic peroxides: methyl ethyl ketone
peroxide (2-butanone peroxide) (waste number U160),
11
α
,
α-dimethylbenzylhydroperoxide
(1-
methyl-1-phenylhydroperoxide) (waste number U096), tetramethylthioperoxydicarbonic diamide
(thiram) waste number U244). These compounds are listed for toxicity and reactivity, but not for
ignitability. Similarly, none of the organic peroxides listed in the USDOT hazardous materials
table are listed under the “5.1” hazard class (oxidizer). Instead, they are either listed as
“forbidden” or under the “5.2” hazard class (organic peroxide).
12
See
49 C.F.R. 172.101 (2006).
11
Methyl ethyl ketone peroxide is the one chemical listed by name in both the USEPA
hazardous waste listings and in the USDOT Hazardous Materials Table. It is a listed hazardous
waste by virtue of toxicity and reactivity. 40 C.F.R. 261.33(f) (2006). It is marked “forbidden”
for transportation by USDOT when it contains more than nine percent oxygen by weight. 49
C.F.R. 172.101 (2006). Thus marked as “forbidden” by USDOT, it would be excluded from the
definitions of “organic peroxide” and “oxidizer” under the corrected USEPA definition of
“oxidizer.”

The same is true of the 1980 version of the USDOT hazardous materials table. The organic
peroxides are listed as either “forbidden” or as “organic peroxide.”
13
See
49 C.F.R. 172.101
(1980).
It might be possible to argue that the exclusion of the more reactive and less reactive
organic peroxides by the exceptions of subsections (a)(4)(i)(A) through (a)(4)(i)(D) leaves only
those organic peroxides that would fit within the definition of “oxidizer.” This argument,
however, is proven false on the basis of the USEPA and USDOT regulations cited above.
USEPA has designated all of the listed organic peroxides as “reactive,” rather than “ignitable.”
USDOT has listed all chemically named peroxides as “forbidden.” Thus, the Board has finds no
support for the categorical USEPA assertion in new note 4 to 40 C.F.R. 261.21(a) that organic
peroxide is a type of oxidizer.
That USDOT did not intend its definition of “organic peroxide” as a subset of the
definition of “oxidizer” is further highlighted by the history of the USDOT definition. USDOT
adopted its initial definition of “oxidizer” in 1964. That original definition was very similar to
the core definition that existed in 1980, with one key difference: the definition used “peroxide”
where “inorganic peroxide” later appeared.
Compare
49 C.F.R. 73.151, as adopted at 29 Fed.
Reg. 18652, 18709 (Dec. 29, 1964)
with
49 C.F.R. 173.151 (1980);
see also
49 C.F.R. 173.127
(2006).
14
In 1976, however, USDOT added a separate definition of “organic peroxide,” as a
separate hazard class, and changed the definition of “oxidizer” to include only “inorganic
peroxide.”
See
49 C.F.R. 173.151, as amended, and 173.151a, as added, at 41 Fed. Reg. 15971,
16069 (Apr. 15, 1976). That USDOT intended the “organic peroxide” hazard class to be
separate from the “oxidizer” hazard class is plain in the brief explanation USDOT gave for these
changes:
173.151 and 173.151a These provide a separate classification and definition for
an oxidizer and an organic peroxide to recognize different hazard characteristics.
41 Fed. Reg. 15971, 15983 (Apr. 15, 1976).
Thus, there is no support for a conclusion that USDOT intended “organic peroxide” to be
“oxidizer” in 1980 when USEPA originally referenced the USDOT definition of “oxidizer” to
help define “ignitable waste.” The addition of the language from former 49 C.F.R. 173.151a to
that of former 49 C.F.R. 173.151 to broaden the definition of “oxidizer” to categorically include
organic peroxides was a material change in the scope of the federal regulations, despite
USEPA’s assertion that it intended no such change. USEPA apparently erred by making this
sodium picryl peroxide, tetramethylene diperoxide. The tables list as in hazard class 5.2:
organic peroxide types B-F.

inclusion.
A more accurate way for USEPA to have dealt with organic peroxides would have been
to omit the definition from former 49 C.F.R. 173.151a when it corrected 40 C.F.R. 261.21(a)(4).
USEPA should also have omitted the references to organic peroxide from note 4 appended to 40
C.F.R. 261.21(a). Assuming that USEPA had to add the definition of “organic peroxide” to that
of “oxidizer” in 40 C.F.R. 261.21(a)(4) to include some organic peroxides that would otherwise
fulfill the definition of “oxidizer,” USEPA should have drafted note 4 in a way that does not
draw from the obsolete and irrelevant USDOT definition of “organic peroxide.” One such
possibility for note 4 follows (with deletions from USEPA’s note 4 indicated as overstruck and
additions indicated with underlining):
Note 4: The DOT regulatory definition of an oxidizer was formerly contained in
49 C.F.R. § 173.151 of 49 CFR, and the definition of an organic peroxide was
contained in paragraph 173.151a. An organic peroxide, which is an organic
compound that includes a bivalent -O-O- structural group and which may be
considered a derivative of hydrogen peroxide in which one or more of the
hydrogen atoms have been replaced by organic radicals, is a type of can be an
oxidizer even though the term “inorganic peroxide” is used by way of example in
the definition.
By drawing on the obsolete USDOT definition of “organic peroxide,” USEPA has
unnecessarily created two additional problems with the definition of “oxidizer.” These arise
from the exclusions from the definition of “organic peroxide.” First, the exclusions are designed
for transportation of materials, not for determining a threat to human health and the environment.
Second, major segments of the exclusions are indefinite in a way that would make them difficult
to implement.
Under the exclusions from the subsidiary definition of “organic peroxide” in 40 C.F.R.
261.21(a)(4), as corrected by USEPA, a material is not an organic peroxide if (1) it is an
explosive, as described in the USEPA rules (in the provision describing the hazardous waste
characteristic of reactivity), which cite to USDOT regulations for making the determination; (2)
it is a material that USDOT has designated as “forbidden” from transportation (either by
reference to the Hazardous Materials Table or a specific regulatory provision); (3) “it is
determined that the predominant hazard of the material containing an organic peroxide is other
than that of an organic peroxide”; or (4) USDOT has determined that the material does not
present a hazard in transportation.
The determination that a material is an explosive made using the USDOT regulations
presents problems with references to outdated USDOT regulations. The exclusion in 40 C.F.R.
261.21(a)(4)(i)(A) cites to the hazardous waste characteristic for “reactivity,” which in turn
refers to USDOT regulations:
§ 261.23 Characteristic of reactivity.
(a) A solid waste exhibits the characteristic of reactivity if a representative sample

54
of the waste has
any
of the following properties:
* * * * *
(8) It is a forbidden explosive as defined in 49 CFR 173.51, or a Class A
explosive as defined in 49 CFR 173.53 or a Class B explosive as defined in 49
CFR 173.88. 40 C.F.R. 261.23(a)(8) (2006)
These references are to obsolete USDOT regulations for the substance of the determination.
Former 49 C.F.R. 173.51 forbids transportation of certain explosives unless they were
expressly allowed under another provision of the USDOT rules.
See
49 C.F.R. 173.51 (1980).
The current version of 49 C.F.R. 173.51 is reworded to prohibit transportation of explosives
unless they are tested, classed, and approved by USDOT.
See
49 C.F.R. 173.51 (2006). The
current counterpart to former 49 C.F.R. 173.51 is 49 C.F.R. 173.54, which sets forth the
prohibition against transportation of explosives on terms very similar to those of former 49
C.F.R. 173.51.
Compare
49 C.F.R. 175.54 (2006)
with
49 C.F.R. 173.51 (1980).
Former 40 C.F.R. 173.53 defined a “Class A Explosive,” and former 40 C.F.R. 173.88
defined a “Class B Explosive.”
See
49 C.F.R. 173.53 and 173.88 (1980). The 1990 USDOT
amendments changed “Class A explosive” to “Division 1.1” or “Division 1.2.” What was
formerly a “Class B Explosive” is now “Division 1.2” or “Division 1.3.” 49 C.F.R. 173.53 table
(2006);
see
49 C.F.R. 173.50(a)(1)-(a)(3) (2006);
see also
55 Fed. Reg. 52402 (Dec. 21, 1990).
Under the current USDOT rules, the various divisions of explosives are defined in terms that are
distinct from those of the former USDOT rules. The former USDOT rules essentially defined
“Class A Explosive” as “detonating or otherwise of maximum hazard.” 49 C.F.R. 173.52(a)(1)
(1980);
see
49 C.F.R. 173.53 (1980) (definition of “Class A explosives”). Those old rules
essentially defined “Class B Explosive” as “flammable hazard.” 49 C.F.R. 173.52(a)(2) (1980);
see
49 C.F.R. 173.88 (1980) (definition of “Class B explosives”). Under the current USDOT
rules, an explosive is Division 1.1 “if the major hazard is mass explosion,” Division 1.2 “if the
major hazard is dangerous projections,” and Division 1.3 “if the major hazard is radiant heat or
violent burning, or both, but there is no blast or projection hazard.” 49 C.F.R. 173.50(b)(1),
(b)(2), and (b)(3) (2006). Thus, there is no clear correlation between the designations “Class A”
or “Class B” under the old USDOT rules and “Division 1.1,” Division 1.2,” or “Division 1.3”
under the existing USDOT rules. This is a defect in the current USEPA definition of “reactive
waste” in 40 C.F.R. 261.23(a)(8) that impacts the exclusions from the definition of “organic
peroxide” for the purpose of defining “oxidizer” in 40 C.F.R. 261.21(a)(4)(i)(A).

The Board corrected the references to the obsolete USDOT rules in UIC Corrections, USEPA
Amendments (January 1, 2005 through June 30, 2005), R06-5, RCRA Subtitle D Update,
USEPA Amendments (January 1, 2005 through June 30, 2005 and August 1, 2005), R06-6,
RCRA Subtitle C Update, USEPA Amendments (January 1, 2005 through June 30, 2005 and
August 1, 2005), R06-7 (Jan. 5, 2006) (consolidated). USEPA has not yet made a corresponding
correction to 40 C.F.R. 261.23(a)(8).

55
There is no problem with the exclusion in 40 C.F.R. 261.21(a)(4)(i)(B) of material
forbidden for transportation under the USDOT rules of 49 C.F.R. 172.101 and 173.21. While
each of these provisions has changed since 1990, their basic natures and subject matters have
not.
Compare
49 C.F.R. 175.21 (2006)
with
49 C.F.R. 173.21 (1980). That USEPA has not
provided for application of the 1980 version of this USDOT rule implies that its current version
is intended.
The third exclusion in 40 C.F.R. 261.21(a)(4)(i)(C) from the definition of “organic
peroxide” is ambiguous. It provides that a material is not an organic peroxide under the
following circumstances:
“It is determined that the predominant hazard of the material containing an
organic peroxide is other than that of an organic peroxide.” 40 C.F.R.
261.21(a)(4)(i)(C) (2006), as amended at 71 Fed. Reg. 40254 (July 14, 2006).
Since this definition is copied from the old version of 49 C.F.R. 173.151a(a)(3) (1980), it is easy
to assume that USDOT has made the determination. Since the text of the current USDOT rule is
essentially identical in its language, there is no problem with a determination made under an
obsolete rule.

49 C.F.R. 173.128(a)(3) (2006) with 49 C.F.R. 173.151a(a)(3) (1980).
However, the USEPA rule leaves it ambiguous whether a determination by USDOT is intended.
That problem would not exist if the USEPA rule cited the corresponding USDOT rule.
Similarly, the fourth and final exclusion in 40 C.F.R. 261.21(a)(4)(i)(D) from the
definition of “organic peroxide” presents problems with an indefinite determination. That
exclusion and its associated note read as follows:
(D) According to data on file with the Pipeline and Hazardous Materials Safety
Administration in the U.S. Department of Transportation (see Note 3), it has been
determined that the material does not present a hazard in transportation.
* * * * *
Note 3: As part of a U.S. Department of Transportation (DOT) reorganization,
the Research and Special Programs Administration (RSPA), which was the office
listed in the 1980 publication of 49 CFR 173.151a for the purposes of determining
that a material does not present a hazard in transport, ceased operations on
February 20, 2005. RSPA programs have moved to the Pipeline and Hazardous
Materials Safety Administration (PHMSA) in the DOT. 40 C.F.R.
261.21(a)(4)(i)(D) and note 4 (2006), as amended at 71 Fed. Reg. 40254 (July 14,
2006).
While this provision makes it clear that USDOT makes the determination that the material does
not present a hazard in transportation, it does not make it clear whether that determination is
made under former 49 C.F.R. 173.151a or current 49 C.F.R. 173.128. If the determination is
made under 173.151a, as would appear intended from the context, USDOT no longer makes
determinations under that provision, and reliance would be on determinations made prior to

56
1990, when USDOT removed that provision from its regulations. If the determination is made
under 173.128, reliance would be placed on the context of current USDOT regulations, but the
definition of “organic peroxide” has changed since 1990.
For the foregoing reasons, the Board believes that the use of the obsolete USDOT
language from the 1980 version of the USDOT regulations actually alters 40 C.F.R. 261.21(a)(4)
in a way not intended by USEPA. Adding the old USDOT definition of “oxidizer” to the
hazardous waste regulations steps backward from using what was formerly a current USDOT
hazard class to using one that is so old that its use will be fraught with uncertainty. It is very
difficult to rely on regulatory mechanisms for determinations that USDOT abandoned in 1990.
Adding the old USDOT definition of “organic peroxide” not only adds this uncertainty from
obsolete regulatory mechanisms, it further broadens the definition of “oxidizer” to include these
materials that USDOT has excluded from its definition of “oxidizer” since 1976. This inclusion
gainsays USEPA’s stated intent of not deviating from the 1980 version of the USDOT
regulations.
As was the case for the 40 C.F.R. 261.21(a)(3) definition of “ignitable compressed gas,”
the use of the language put forward by USEPA from the 1980 version of the USDOT regulations
would cause problems. It would, at best, result in a substantive change in the definition of
“ignitable waste.” At worst, it could result in a definition that is too vague to be uniformly
enforceable. The Board is reluctant to achieve either result.
Rather than follow the language used by USEPA and substantively amend the definition
of “ignitable waste” where USEPA has made it clear that no such change is intended, the Board
would prefer to maintain the
status quo ante
, as intended by USEPA. The operative concept
prior to the July 14, 2006 USEPA corrections was that a USDOT-designated “oxidizer” is
“ignitable waste.” USDOT has relied on 49 C.F.R. 173.127 for that designation since 1990.
That designation has not included “organic peroxide” as described in current 49 C.F.R. 173.128
or former 173.151a.
The Board has not amended the text of 35 Ill. Adm. Code 721.121(a)(4) (corresponding
with 40 C.F.R. 261.21(a)(4)) to include the language of the 1980 version of 49 C.F.R. 173.151
defining “oxidizer.” The Board has chosen not to broaden the definition of “oxidizer” by adding
the definition of “organic peroxide”—from either of the 1980 version of 49 C.F.R. 173.151a or
the current version of 49 C.F.R. 173.128. The Board has retained the existing text of 35 Ill.
Adm. Code 721.121(a)(4) as corrected in 2006 to reflect the 1990 USDOT amendments.

the Board note appended to this provision, however, to note the federal correction of July 14,
2006 and explain the differences between the text of this subsection (a)(4) and corresponding 40
C.F.R. 261.21(a)(4).

Corrections to 40 C.F.R. 264.223(b)(1), 264.304(b)(1), 265.224(b)(1), and

The USEPA correction of the spelling of “exceedence” to “exceedance” at 40 C.F.R.
264.223(b)(1), 264.304(b)(1), 265.224(b)(1), and 265.303(b)(1) runs contrary to the Board’s
historic approach to this word. In SDWA Update, USEPA Amendments (July 1, 2000 through
December 31, 2000; Radionuclides), R01-20 (Oct. 4, 2001), the Board confronted the disparate
spellings of this word. The Board stated as follows in the opinion accompanying those
amendments:
The word “exceedence” or “exceedance” is relatively new to the English
language. Of all the references available to the Board, the word appears only in
the Encarta World English Dictionary.
10
In that reference the word appears as
“exceedance.” Encarta World English Dictionary 620 (1999). The word appears
as “exceedance” in the definition of “exceedance probability” in another
reference. Dictionary of Environmental and Civil Engineering 195 (2000). The
Board has so far used the spelling, “exceedance,” as used by USEPA where the
word is used in the federal regulations. See,
e.g.
, 40 C.F.R. 141.87(d)(2) and
141.201(a)(3)(ii). However, the word “exceed” derives from the Latin
excedere,
” and the standard practice is to add the suffix “-ence” or “-ance” to
create the noun form depending on the vowel at the end of the Latin word that
forms the root, although there are enough exceptions to create confusion on the
spellings of the words created in this way. New Shorter Oxford English
Dictionary (4th ed. 1993). Thus, the standard rule would require the spelling
“exceedence.”
* * * * *

Notably, among the references checked, the word did not appear in the Random
House Webster’s Unabridged Dictionary (2d ed. 1998), the New Shorter Oxford
English Dictionary (4th ed. 1993), The Chambers Dictionary (2000), or the
Langenscheidt’s New College Merriam-Webster English Dictionary (2000).
SDWA Update, USEPA Amendments (July 1, 2000 through December 31, 2000;
Radionuclides), R01-20 (Oct. 4, 2001) at pp. 9-10.
The Board then opted to follow the standard rule for Latinate words and used the spelling
“exceedence.” The Board later changed the spelling to “exceedence” in the RCRA rules in
RCRA Subtitle C Update, USEPA Amendments (July 1, 2002 through December 31, 2002),
R03-18, at p. 64-65 (June 5, 2003).
As a result of the recent USEPA change of the spelling from “exceedence” to
“exceedance,” the Board has reconsidered the previous position. The Board has chosen to
follow the USEPA lead and change the spelling to “exceedance” in the Illinois rules. It appears
that since the Board took its previous position with regard to the spelling, there has been a

58
growing tendency to use the spelling “exceedance.” This is the spelling used in the relatively
new fourth edition of the American Heritage Dictionary.
See
“exceedance.” Dictionary.com.
The American Heritage Dictionary of the English Language, 4th ed. Houghton Mifflin
Company, 2004. (http://dictionary.reference.com/browse/exceedance (accessed: February 19,

(http://dictionary.reference.com/browse/exceedance (accessed: February 19, 2008)).
The Board searched the entire text of the Illinois hazardous waste regulations and
discovered several other appearances of the spelling “exceedence.” All are in segments already
open in this proceeding. Thus, the Board will correct each spelling to “exceedance” at this time.
The Board will change the spelling at Sections 703.213(f), 724.353(b)(1), 724.936(a)(2)(A)(ii)
and (a)(2)(B), 724.965(a)(4), 726.206(d)(5), and 726.207(c)(3) (to agree with this spelling at
corresponding 40 C.F.R. 270.27(a)(6), 264.1036(a)(2)(A)(ii) and (a)(2)(B), 264.1065(a)(4),
266.106(d)(5), and 266.107(c)(3), respectively). Upon searching the parallel segments of federal
text, though, the Board has found a single occurrence of “exceedence” in the federal text that
USEPA has not yet corrected. This appears at 40 C.F.R. 270.315(f), which corresponds with 35
Ill. Adm. Code 703.352(e)(6). The Board has changed this spelling also.
Corrections to 40 C.F.R. 265.405(a)(1) and two to appendix VI to 40 C.F.R. 265
(corresponding with 35 Ill. Adm. Code 725.505(a)(1) and Appendix F to 35 Ill. Adm.
Code 725)
Three of USEPA’s corrections instill minor errors in the rules. The Board has not made
the corresponding corrections. In 40 C.F.R. 265.405(a)(1), USEPA changed the text to read
“§§ 261.21 or 261.23.” Use of “§§” is the plural abbreviation for “sections.” The text “261.21
or 261.23” is in the disjunctive, so the singular is appropriate. Appendix VI to 40 C.F.R. 264
changed the spellings “dimethylolpropane” to “dimethylpropane” and “sulfone” to “sultone.”
The proper spellings of these chemical species are indeed “dimethylolpropane” and “sulfone.”
The Board requested public comment on the incorporation of the July 14, 2008 federal
hazardous waste and used oil corrections into the Illinois regulations. In particular, the Board
requested comments on six specific aspects of these amendments in a series of queries. The
Agency responded to each of these six with comments. The following six paragraphs outline the
Board queries and the Agency responses to each.
First, the Board queried, should the Board use the current USDOT definition of
“flammable gas” in place of adding the language of the obsolete 1980 definition of “flammable
compressed gas” as a segment of the definition of “ignitable waste,” as was done by USEPA? In
PC 8, the Agency stated “that it is a good idea to update the definition to make it current with
other regulations (such as USDOT’s) as well as accounting for any advances in science to testing
methods that have been developed since 1980.” PC 8 at 2, numbered ¶ 1.
Second, the Board queried, if the Board is to use the language of the 1980 definition of
“flammable compressed gas” to define “ignitable waste,” how should the Board best incorporate

59
the obsolete Bureau of Explosives methods into the Illinois rules? In PC 8, the Agency stated,
“The Agency suggests not using the 1980 definition.” PC 8 at 2, numbered ¶ 2.
Third, the Board queried, should the Board use the current USDOT definition of
“oxidizer” in place of adding the language of the obsolete 1980 definition of “oxidizer” as a
segment of the definition of “ignitable waste,” as was done by USEPA? In PC 8, the Agency
stated, “the Agency does not believe the Board should use obsolete definitions. * * * The
Board’s proposed approach would prevent problems with USEPA’s approach (i.e., using
obsolete methods and regulations for the outmoded hazard class.” PC 8 at 2, numbered ¶ 3.
Fourth, the Board queried, should the Board include the language of the obsolete 1980
USDOT definition of “organic peroxide” as a segment of the definition of “oxidizer” for the
purposes of defining “ignitable waste,” as was done by USEPA? In PC 8, the Agency directed
attention to the immediately foregoing response. PC 8 at 2, numbered ¶ 4.
Fifth, the Board asked, should the Board depart from past preference, follow USEPA’s
lead, and change the spelling “exceedence” to “exceedance”? In PC 8, the Agency stated that it
has no preference as to the spelling. PC 8 at 2, numbered ¶ 5.
Finally, the Board queried, does the Board correctly decline to make three corrections to
Sections 725.505(a)(1) and Appendix F to correspond with USEPA corrections to 40 C.F.R.
265.405(a)(1) and two to appendix VI to 40 C.F.R. 265 that the Board believes to have been
errors, as described immediately above? In PC 8, the Agency stated, “The Agency defers to the
Board’s judgment of this issue.” PC 8 at 2, numbered ¶ 5.
As a result of the public comments received, the Board made no substantive changes to
the amendments proposed on March 20, 2008 to accommodate the federal corrections of July 14,
2006. Any non-substantive revisions in the text are listed in Table C, which begins on page 135
of this opinion.
Conditional Exclusion of Used CRTs from the Definition of Solid Waste--Sections 720.110
and 721.104 and Subpart E of Part 721
16
On July 28, 2006 (71 Fed. Reg. 42928), USEPA adopted a conditional exclusion for used
cathode ray tubes (CRTs) from the definition of solid waste. Under the exclusion, used, intact
CRTs that are not disposed of or accumulated speculatively are not solid waste. If the CRTs are
intended for export, they are excluded if the person managing them fulfills specified notice and
consent requirements. If the used CRTs are broken, specified minimal management, storage,
transportation, accumulation, and export requirements apply. Requirements similar to those that
apply to used, broken CRTs apply to the glass extracted from used CRTs.
The Board incorporated the federal July 28, 2006 exclusion of CRTs from the definition
of solid waste without substantive deviation from the corresponding federal text. The deviations
16
Sections 721.138, 721.139, 721.140, 721.141.

60
from the text of the federal amendments are restricted to those structural and stylistic changes
needed to make the text comport with the
Illinois Register
format and the Board’s preferred style
and to add clarity and ease of use for the regulated community. Table A, which begins on page
103 of this opinion, itemizes the various revisions made in the federal text in adapting it into the
State regulations.
The Board does not review the substance and merits of the underlying federal action in
an identical-in-substance proceeding, except to the extent that it may be necessary to do so in
order to incorporate the federal provisions into the Illinois regulations. Persons interested in the
details of the federal amendments should consult the July 28, 2006
Federal Register
notice.
Only one aspect of the CRT exclusion warrants particular consideration here, since the
Board has found it necessary to depart from the language of the federal regulations in only two
significant ways. The first relates to the use of a key, defined term. USEPA added a definition
of “CRT processing” to 40 C.F.R. 260.10. This phrase is used in new 40 C.F.R. 261.39(b),
which outlines the requirements that apply to this activity. In 40 C.F.R. 261.39(a), however,
USEPA imposes requirements “prior to processing.” To clarify that “CRT processing” is
intended, the Board used this defined phrase in corresponding 35 Ill. Adm. Code 721.139(a).
Similarly, USEPA used the phrases “processed CRT glass” and “glass from used CRTs” in 40
C.F.R. 261.39(c). The Board changed these to use the defined term also, so that they both now
read “glass from CRT processing” in corresponding 35 Ill. Adm. Code 721.139(c). The Board
has further changed the phrase “after processing” in this same subsection (c) to “after CRT
processing.” Finally, USEPA used the phrase “glass from used CRTs” in 40 C.F.R. 261.39(d).
The Board changed this to “glass from CRT processing” in corresponding 35 Ill. Adm. Code
721.139(c) to standardize the usage and clarify the intent.
The second significant deviation from the federal text relates to export notifications.
USEPA requires in 40 C.F.R. 261.39(a)(5) and 261.41 that a person who exports used CRTs
submit a prior notification to USEPA. Based on 35 Ill. Adm. Code 261.39(a)(5)(v), it is clear
that USEPA will act in a central role in obtaining export authorizations from receiving countries.
Thus, throughout the text of corresponding 35 Ill. Adm. Code 721.139(a)(5) and 721.141, the
Board has required that the person exporting the CRTs submit the export requests to USEPA.
For the purposes of aiding enforcement and Agency inspections of facility records, the Board has
required parallel submissions by the person exporting the CRTs to the Agency. The Board
added a Board note to Section 721.139(a) that explains the parallel submissions and adds that the
parallel submissions are not intended to require or authorize a parallel authorization by the
Agency.
The Board requested public comment on the incorporation of the July 28, 2006 exclusion
of CRTs from the definition of solid waste. In particular, the Board requests comment on the
changes in the language discussed above to use the defined term “CRT processing” in place of
other phrases used by USEPA. The Board also specifically requested comment on the following
three questions posed by export notification requirements: (1) Is it necessary to add the Agency
as a recipient of the notifications? (2) Is it necessary to include the export notification
requirements in the Illinois rule if USEPA is the entity that is to receive and process them? (3)

61
Would it be better to simply cross-reference to the federal export notification requirements than
to include them in the Illinois rules? In PC 8, the Agency responded as follows:
The Agency believes that it is important to have parallel notifications to the
Agency and USEPA. If the Agency is not notified, it will not know the export
activity that is going on and would, therefore, not be able to perform inspections.
Although the federal government does its own inspections, the Agency feels it is
critical that we also perform inspections. PC 8 at p.3.
As a result of the public comments received, the Board made no substantive changes to
the amendments proposed on March 20, 2008 to accommodate the federal amendments of July
28, 2006 relating to exclusion of used CRTs from the definition of solid waste. Any non-
substantive revisions in the text are listed in Table C, which begins on page 135 of this opinion.
Agency or Board Action
Section 7.2(a)(5) of the Act requires the Board to specify those portions of the program
over which USEPA will retain decision making authority. Based on the general division of
functions within the Act and other Illinois statutes, the Board is also to specify which State
agency is to make decisions.
In situations in which the Board has determined that USEPA will retain decision-making
authority, the Board has replaced “Regional Administrator” with USEPA, so as to avoid
specifying which office within USEPA is to make a decision.
In some identical-in-substance rules, certain decisions pertaining to a permit application
are not appropriate for the Agency to consider. In determining the general division of authority
between the Agency and the Board, the following factors should be considered:
1.
Whether the entity making the decision is applying a Board regulation, or taking
action contrary to,
i.e.
, “waiving,” a Board regulation. It generally takes some
form of Board action to “waive” a Board regulation.
2.
Whether there is a clear standard for action such that the Board can give
meaningful review to an Agency decision.
3.
Whether the action would result in exemption from the permit requirement itself.
If so, Board action is generally required.
4.
Whether the decision amounts to “determining, defining or implementing
environmental control standards” within the meaning of Section 5(b) of the Act.
If so, it must be made by the Board.
There are four common classes of Board decisions: variance, adjusted standard, site-
specific rulemaking, and enforcement. The first three are methods by which a regulation can be
temporarily postponed (variance) or adjusted to meet specific situations (adjusted standard or

62
site-specific rulemaking). There often are differences in the nomenclature for these decisions
between the USEPA and Board regulations.
Table 1:
Tabulation of Amendments Needed to Complete the
Federal Manifest Amendments of March 4, 2005
As discussed above on pages 2 and 3 of this opinion, the Board is using this as the first
opportunity after September 6, 2006 to complete amendments based on the amendments to the
hazardous waste manifest system that USEPA adopted on March 4, 2005. USEPA in those
amendments codified two parallel versions of its rules, one effective until September 6, 2006 and
the other effective after that date. In the corresponding update docket, UIC Corrections, USEPA
Amendments (January 1, 2005 through June 30, 2005, R06-5, RCRA Subtitle D Update, USEPA
Amendments (January 1, 2005 through June 30, 2005), R06-6, RCRA Subtitle C Update
(January 1, 2005 through June 30, 2005), R06-7 (Jan. 5, 2006) (consolidated), the Board could
not codify both versions using the same subsection designations, as did USEPA, so the Board
restructured the rules to accommodate the two versions under different designations. The
amendments that appear in the following table are necessary to remove the obsolete provisions
and restructure the Illinois rules to again agree with the structure of the corresponding federal
provisions.

It has previously been the practice of the Board to include an historical discussion in its

through December 31, 1999), R00-13 (May 18, 2000), the Board indicated that it would cease
this practice. Therefore, for a complete historical summary of the Board’s RCRA Subtitle C and
UIC rulemakings and programs, interested persons should refer back to the May 18, 2000
opinion and order in R00-13.
The historical summary contains all Board actions taken to adopt and maintain these
programs since their inception and until May 18, 2000. It includes a listing of all site-specific
rulemaking and adjusted standards proceedings filed that relate to these programs. It also lists
all USEPA program authorizations issued during that timeframe. As necessary the Board will
continue to update the historical summary as a segment of the opinion in each RCRA Subtitle C
and UIC update docket, but those opinions will not repeat the information contained in the
opinion of May 18, 2000, in docket R00-13.
The following summarizes the history of the Illinois RCRA Subtitle C hazardous waste
and UIC programs since May 18, 2000:

The Board has taken several actions since May 18, 2000 relating to administration of the
Illinois hazardous waste program. These actions involved petitions for relief from various
aspects of the regulations.
The Board made final determinations on the merits of three petitions for a solid waste
determination. Pursuant to 35 Ill. Adm. Code 721.131 (2006), the Board may determine that
specific waste is not solid waste. The following listing of petitions for hazardous waste delisting
includes one petition for modification of an earlier-granted solid waste determination that is still
pending before the Board:
AS 01-7
In re
Petition of Progressive Environmental Services, Inc. for an Adjusted
Standard under 35 Ill. Adm. Code 720.131(c), AS 02-7 (Jan. 10, 2002)
(used automotive antifreeze).
AS 02-2
In re
Petition of World Recycling, Inc. d/b/a Planet Earth Antifreeze for
an Adjusted Standard under 35 Ill. Adm. Code 720.131, AS 02-2 (May 2,
2002) (used automotive antifreeze).
AS 06-4
In re
Petition of Big River Zinc Corporation for an Adjusted Standard
under 35 Ill. Adm. Code 720.131(c), AS 06-4 (Nov. 16, 2006) (K061
electric arc furnace dust used as a feedstock for zinc recycling).
AS 08-9
In re
Petition of Big River Zinc Corporation for an Adjusted Standard
under 35 Ill. Adm. Code 720.131(c), AS 08-9 (petition filed April 1, 2008,
on which a Board decision is pending; seeking modification of the solid
waste determination granted in Petition of Big River Zinc Corporation for
an Adjusted Standard under 35 Ill. Adm. Code 720.131(c), AS 99-3 (May
6, 1999)).
The Board made final determinations on the merits of two petitions for hazardous waste
delisting. Pursuant to 35 Ill. Adm. Code 721.122 (2006), the Board may determine that the
character of a specific listed hazardous waste warrants “delisting” that waste. The Board
dismissed another petition for hazardous waste delisting on procedural grounds. The following
listing of petitions for hazardous waste delisting includes one petition still pending before the
Board and another recently filed that the Board has not yet accepted for hearing:
AS 05-7
In re
Petition of Waste Management of Illinois, Inc. for RCRA Waste
Delisting under 35 Ill. Adm. Code 720.122 for Solid Treatment Residual
for CID Recycling and Disposal Facility Biological Liquid Treatment
Center, AS 05-7 (Dec. 15, 2005) (denied on the merits; involving F039
leachate from the disposal of multiple listed waste streams).

RCRA Delisting Adjusted Standard Petition of Peoria Disposal
Company, AS 08-10 (petition filed April 25, 2008, on which no order has
yet issued from the Board; involving stabilized K061 electric arc furnace

One petition filed before the Board requested relief from a substantive requirement of the
hazardous waste regulations. The Board granted relief on that petition from a permit
requirement applicable to hazardous waste management facilities:
AS 00-15
In re
Petition of Heritage Environmental Services, LLC. for an Adjusted
Standard from 35 Ill. Adm. Code 702.126(d)(1), AS 00-15 (Feb. 1, 2001)
