    Adopted Rule. Final Order.
    OPINION OF THE BOARD (by E.Z. Kezelis):
    Under Sections 7.2 and 22.4(a) of the Environmental Protection Act (Act) (415 ILCS 5/7.2
    and 22.4(a) (1998)), the Board today adopts amendments to the Illinois regulations that are “identical in
    substance” to hazardous waste regulations that the United States Environmental Protection Agency
    (USEPA) adopted to implement Subtitle C of the federal Resource Conservation and Recovery Act of
    1976 (RCRA Subtitle C) (42 U.S.C. §§ 6921
    et seq
    . (1998)). The nominal timeframe of this docket
    includes federal RCRA Subtitle C amendments that USEPA adopted in the period January 1, 1999,
    through June 30, 1999.
    Sections 7.2 and 22.4(a) provide for quick adoption of regulations that are identical in
    substance to federal regulations that USEPA adopts to implement Sections 3001 through 3005 of
    RCRA (42 U.S.C. §§ 6921-6925 (1998)). Section 22.4(a) also provides that Title VII of the Act and
    Section 5 of the Administrative Procedure Act (APA) (5 ILCS 100/5-35 and 5-40 (1998)) do not
    apply to the Board’s adoption of identical-in-substance regulations. The federal RCRA Subtitle C
    regulations are found at 40 C.F.R. 260 through 266, 268, 270, 271, 273, and 279.
    This opinion supports the order that the Board also adopts today. The Board will wait 30 days
    for USEPA to review the amendments, as provided in the agreement between USEPA and the State of
    Illinois relating to federal authorization of the State program, in order to allow USEPA an additional
    opportunity to review the amendments before they become effective. We will then file the amendments
    with the Secretary of State and submit Notices of Adopted Amendments for publication in the
    Illinois
    Register
    .
    FEDERAL ACTIONS CONSIDERED IN THIS RULEMAKING
    The following briefly summarizes the federal actions considered in this rulemaking.

    2
    Docket R00-5: January 1, 1999, through June 30, 1999, RCRA Subtitle C
    Amendments
    USEPA amended the federal RCRA Subtitle C regulations on three occasions during the period
    January 1, 1999, through June 30, 1999. Each is summarized below:
    64 Fed. Reg. 3382 (January 21, 1999)
    USEPA adopted clarifying and corrective amendments to the 40 C.F.R. 264, Subpart CC and
    265, Subpart CC organic material emission rules (Subpart CC rules) applicable to hazardous
    waste tanks, containers, and surface impoundments.
    64 Fed. Reg. 6806 (February 11, 1999)
    USEPA adopted a temporary exemption of certain petroleum refining wastes from the definition
    of hazardous waste.
    64 Fed. Reg. 25408 (May 11, 1999)
    USEPA adopted corrections and clarifications to several of its Phase IV rulemaking actions: its
    May 12, 1997 (62 Fed. Reg. 25998) and May 26, 1998 (63 Fed. Reg. 28556) Phase IV
    rules; its August 31, 1998 (63 Fed. Reg. 46332) administrative stay of aspects of its May 26,
    1998 rule; its September 4, 1998 (63 Fed. Reg. 47409) emergency amendment of the
    carbamate rule; and the September 24, 1998 (63 Fed. Reg. 51254) amendments relating to
    spent potliners.
    The Board has already acted with regard to two of the federal actions that occurred in the current
    update period. See RCRA Update, USEPA Regulations (July 1, 1998, through December 31, 1998)
    (June 17, 1999), R99-15. No further action is necessary as to one federal action, and only partial
    action is required to complete the Board’s actions as to the other. The listing of the two federal actions
    on which the Board has already acted follows, together with a brief explanation as to why no action or
    only partial action is necessary:
    64 Fed Reg. 6806 (February 11, 1999)
    The Board fully incorporated the temporary exemption of certain petroleum refining wastes into
    update docket R99-15, so no further action will be necessary.
    64 Fed. Reg. 25408 (May 11, 1999)
    The Board included most, but not all, of the USEPA corrections and clarifications to its Phase
    IV rulemaking actions. The Board adopted all of the federal amendments except those to 40
    C.F.R. 262, since corresponding 35 Ill. Adm. Code 722 was not included in the proposal for
    public comment in RCRA Update, USEPA Regulations (July 1, 1998, through December 31,
    1998) (April 23, 1999), R99-15. The Board must complete the amendments in this docket,
    R00-5.

    3
    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, we have not identified any USEPA actions since June 30, 1999, that further
    amend the RCRA Subtitle C hazardous waste rules involved in this proceeding. When the Board
    observes an action outside the nominal timeframe of a docket that would require expedited
    consideration in the pending docket, the Board will expedite consideration of those amendments.
    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. If
    the Board identifies any federal actions that fulfill these criteria prior to final action on the present
    amendments, it may include those amendments in the present update docket R00-5. In this instance, no
    later amendments affect the subject matter involved in this proceeding.
    Unrelated Federal Actions Having an Ancillary Impact on the Illinois RCRA Subtitle C
    Regulations
    In addition to the amendments to the federal RCRA Subtitle C regulations, other, unrelated
    federal amendments might have an effect on the corresponding Illinois rules. Most notably, 35 Ill. Adm.
    Code 720.111 includes several incorporations of federal regulations by reference, and USEPA has
    amended 40 C.F.R. 136, which is included among the incorporated references. The federal
    amendments to 40 C.F.R. 136 are as follows, along with a description of the Board action each
    requires, if any:
    64 Fed. Reg. 4975 (February 2, 1999)
    USEPA amended the 40 C.F.R. 136 methods for whole effluent toxicity testing for the
    purposes of compliance with the Clean Water Act.
    64 Fed. Reg. 26315 (May 14, 1999)
    USEPA approved the use of a new method for analyzing oil and grease for the purposes of
    compliance with the Clean Water Act and RCRA regulations.
    64 Fed. Reg. 30417 (June 8, 1999)
    USEPA amended its guidance on the analysis of mercury in water for the purposes of
    compliance with the water quality requirements of the Clean Water Act.
    Summary Listing of the Federal Actions Forming the Basis of the Board’s Actions in
    this Docket
    Based on the foregoing, the federal actions that form the basis for Board action in this update
    docket are as follows, in chronological order:

    PUBLIC COMMENTS
    The Board adopted a proposal for public comment in this matter by order dated September 23,
    1999. “Notices of Proposed Amendments” appeared in the October 8, 1999 issue of the
    Illinois
    Register
    , at 23 Ill. Reg. 12087 (Part 720), 12185 (Part 722), 12195 (Part 724), and 12100 (Part
    725). The Board accepted public comments on the proposal for a 45-day period following publication
    in the
    Illinois Register.
    The comment period expired on November 22, 1999.
    The Board received two public comments during the public comment period. Those comments
    are as follows:
    PC 1
    USEPA Region V, dated November 23, 1999, letter from Richard T. Traub, Chief,
    State Programs and Authorization Section (received November 24, 1999).
    PC 2
    Illinois Environmental Protection Agency (the IEPA), dated November 17, 1999,
    Response to Public Comment Period from Susan J. Schroeder, Associate Counsel,
    Division of Legal Counsel (received November 24, 1999).
    In PC 1, USEPA stated that it has no comments on the “RCRA Cluster VIII” requirements that
    appeared in the
    Federal Register
    during the period January 1, 1999, through June 30, 1999. In PC 2,
    the IEPA voiced its concern over two narrow aspects of the proposed amendments. The IEPA
    comments are discussed below (at pages seven through nine) in the appropriate segments of the
    substantive discussion of the amendments.
    In addition to the public comments, the Board also received a series of four documents from the
    Joint Committee on Administrative Rules (JCAR) (one for each Part involved in this proceeding) entitled
    “Identical First Notice Line Numbered Version.” Each of these documents contain those changes that
    JCAR made prior to the October 8, 1999 publication of these amendments in the
    Illinois Register
    .
    The changes accepted by the Board are listed in the table entitled, “Revisions to the Text of the
    Proposed Amendments in Final Adoption,” that begins at page 14 of this opinion. The changes not
    accepted by the Board, together with a brief explanation, appear in the table entitled, “Requested

    5
    Revisions to the Text of the Proposed Amendments Not Made in Final Adoption,” beginning at page
    14.
    The Board adopts these amendments, having first made the changes necessitated by public
    comment. The Board will delay filing these adopted rules with the Secretary of State for 30 days after
    the date of this opinion and order, or until after January 1, 1999, in order to allow additional time for
    USEPA to review the adopted amendments before they are filed and become effective. The complete
    text of the adopted amendments appears in a separate order adopted this day.
    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 a
    discussion of the amendments and actions undertaken in direct response to the federal actions involved
    in this proceeding. This first series of discussions is organized by federal subject matter, generally
    appearing in chronological order of the significant
    Federal Register
    notices involved. Finally, this
    discussion closes with a description of the amendments and actions that are not directly derived from the
    federal actions.
    General Revisions and Deviations from the Federal Text
    In incorporating the federal rules into the Illinois system, some minimal 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 problems with the
    federal text itself. The Board conforms the federal text to the Illinois rules and regulatory scheme and
    corrects errors that we see in the text as we engage in 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 of the date of this opinion, the most recent version of the
    Code of Federal Regulations
    available to the Board is the July 1, 1998 version. Thus, we have updated all citations to the 1998
    version, 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

    6
    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 “shall” for “will;” 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,” “shall” is used when the
    subject of a sentence has a duty to do something. “Must” is used when someone has to do something,
    but that someone is not the subject of the sentence. “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.”
    JCAR has requested that the Board refer to the USEPA 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 USEPA as “USEPA.” We will continue this conversion in future rulemakings as
    additional sections otherwise become open to amendment. We will further convert “EPA” used in
    federal text to “USEPA,” where USEPA is clearly intended.
    The Board has assembled tables to aid location of those alterations and to briefly outline their
    intended purpose. The tables set forth the miscellaneous deviations from the federal text and
    corrections to the pre-amended base text of the rules in detail. The tables are set forth and explained
    beginning at page 10. There is no further discussion of most of the deviations and revisions elsewhere in
    this opinion.
    One alteration of the base regulatory text and one to the verbatim text of the federal
    amendments warrant specific discussions. The alteration of the base text was the addition of “USDOT”
    as a defined term, in order to avoid the use of explanatory parentheticals at multiple locations in the text.
    The new definition of “USDOT” appears at Section 724.981, with the rest of the definitions pertaining
    to the “Subpart CC” rules. The Board has replaced “U.S. Department of Transportation (USDOT)”
    with the abbreviation “USDOT” at Sections 724.986(c)(1)(A), (d)(1)(A), and (f) and
    725.987(c)(1)(A), (d)(1)(A), and (f). The discussion of the alteration of the federal text is set forth in
    the topical discussion of the “Subpart CC” rule amendments that immediately follows.
    Discussion of Particular Federal Actions
    Subpart CC Corrections—Section 722.134 and Subparts CC to Parts 724 and 725
    USEPA adopted amendments, corrections, and clarifications to its Subpart CC rules on
    January 21, 1999 (64 Fed. Reg. 3382). The rules at 40 C.F.R. 264, Subpart CC and 265, Subpart
    CC set forth requirements for the control of organic material emissions for tanks, containers, and surface
    impoundments that contain hazardous waste. USEPA initially adopted the Subpart CC rules on
    December 6, 1994 (59 Fed. Reg. 62896). USEPA subsequently delayed the effective date four times

    7
    to further consider the Subpart CC rules and corrections and clarifications to them: on May 19, 1995
    (60 Fed. Reg. 26828); November 13, 1995 (60 Fed. Reg. 56952); June 5, 1996 (61 Fed. Reg.
    28508); and November 25, 1996 (61 Fed. Reg. 59931). Ultimate compliance with the Subpart CC
    rules was delayed by these actions until December 6, 1996. During that time, USEPA published
    corrections and amendments to the Subpart CC rules on February 9, 1996 (61 Fed. Reg. 4903);
    November 25, 1996 (61 Fed. Reg. 59932); and December 8, 1997 (62 Fed. Reg. 64636). In these
    Subpart CC actions, USEPA also corrected , Subparts AA and BB of 40 C.F.R. 264. Subparts AA
    and BB regulate organic material emissions from process vents and equipment leaks. As in those earlier
    actions, this January 21, 1999 action also involves corrections to rules other than the Subpart CC rules
    of 40 C.F.R. 264 and 265; specifically, it involves amendments to 40 C.F.R. 262.34 and 264, Subpart
    AA.
    The Board has incorporated the federal amendments into Section 722.134 and the appropriate
    segments of Subparts AA and CC of Part 724 and Subpart CC of Part 725. We have done so with
    only minor deviations from the text of the federal amendments. Persons interested in the substance of
    the underlying federal action should refer to the notice that appeared in the January 21, 1999 issue of
    the
    Federal Register
    . The tables that begin on page 8 of this opinion outline the minor deviations that
    the Board has made in adapting the text of the federal amendments.
    Two deviations from the literal text of the federal amendments warrant specific discussion.
    First, the Board has altered “either or” from 40 C.F.R. 264.1084(h)(3) and 265.1085(h)(3) to read
    “either of” in corresponding Sections 724.984(h)(3) and 725.985(h)(3). Second, the Board has
    deleted the “as specified in paragraph (h)(3)(i) or (h)(3)(ii) of this section” language from these same
    two parallel federal provisions. As a substitution for this language, the Board has added the word “two”
    in between the words “following” and “conditions.” The Board believes the revised language is more
    straightforward.
    Also worth noting is that the IEPA addressed the amendment of the Section 724.931 definition
    of “open-ended valve or line” to replace the phrase “process fluid” with “hazardous waste.” The IEPA
    expressed a concern that this alteration of the regulatory text makes it ambiguous whether the definition
    would apply to valves handling reclaimed liquid from a recycling unit. The IEPA requested that the
    Board not change the definition or, alternatively, that we clarify whether the definition should apply to
    reclaimed product.
    The Board cannot alter the language of the proposed amendments to the definition of “open-
    ended valve or line.” The proposed language reflects the language dictated by USEPA. Examination of
    USEPA’s preamble discussion of its amendments to the definition indicate that it altered the definition
    because “the subpart BB rules only apply to equipment (
    e.g.
    , and open-ended valve or line) that
    contains or contacts hazardous waste . . . .” Thus, USEPA intended that the Subpart BB rules and the
    definition of “open-ended valve or line” apply only to equipment used to manage “hazardous waste.”
    The Board cannot alter the federal language or clarify the rules in any way that would change the
    meaning intended by USEPA.

    8
    Phase IV LDR Corrections and Clarifications—Section 722.134
    On May 11, 1999 (64 Fed. Reg. 25408), USEPA adopted corrective and clarifying
    amendments to five of its Phase IV LDR rulemaking actions, including those of May 12, 1997 (62 Fed.
    Reg. 25998); May 26, 1998 (63 Fed. Reg. 28556); August 31, 1998 (63 Fed. Reg. 46332);
    September 4, 1998 (63 Fed. Reg. 47409); and September 24, 1998 (63 Fed. Reg. 51254). The
    Board adopted most, but not all, of the May 11, 1999 federal amendments in the prior RCRA Subtitle
    C update docket RCRA Update, USEPA Regulations (July 1, 1998, through December 31, 1998)
    (June 17, 1999), R99-15. The Board adopted all of the federal amendments except those to 40
    C.F.R. 262. Corresponding 35 Ill. Adm. Code 722 was not included in the proposal for public
    comment, so the Board could not amend that Part.
    The Board completes the May 11, 1999 federal amendments in this docket, R00-5, by making
    the necessary amendments to Section 722.134(d). The amendments are limited to the correction of
    cross-references. The Board has incorporated the federal amendments without deviation from the
    federal text. Persons interested in the details of the federal amendments should consult the May 11,
    1999
    Federal Register
    notice. Those interested in the major segments of the federal amendments
    incorporated into the Illinois hazardous waste rules in the prior update docket should refer to the opinion
    and order in RCRA Update, USEPA Regulations (July 1, 1998, through December 31, 1998)
    (June 17, 1999), R99-15.
    The Board requested public comment on our completion of the May 11, 1999 federal
    amendments to the Phase IV LDR rules. The IEPA commented on one narrow aspect of the federal
    Phase IV LDR amendments in response to our request. Regrettably, the Board cannot alter the text of
    the rules in response to the IEPA comment.
    The IEPA did not question the text of Section 722.134. Instead it noted a couple of deviations
    in the text of the definition of “soil” in Section 728.102 from the corresponding federal definition of 40
    C.F.R. 268.2(c). The IEPA suggested that the Board change the definition to exactly reflect the federal
    text.
    The Board agrees with the IEPA that in the Section 728.102 definition of “soil” we should
    change “debris” to “soil” and “hazardous debris” to “contaminated soil” in the final sentence, as
    amended by USEPA on May 11, 1999, at 64 Fed. Reg. 25414. However, the Board did not propose
    to amend Part 728 in our October 8, 1999 Notice of Proposed Amendments. Since Part 728 is not
    open in this proceeding, we cannot proceed to make the changes in Section 728.102 at this time. We
    will complete the IEPA-suggested revisions in the next routine update docket.
    Incorporation of 40 C.F.R. 136 by Reference—Section 720.111
    USEPA adopted multiple amendments to 40 C.F.R. 136, which are the Clean Water Act
    analytical procedures, on February 2, 1999 (64 Fed. Reg. 4975); May 14, 1999 (64 Fed. Reg.
    26315); and June 8, 1999 (64 Fed. Reg. 30417). The methods affected relate to whole effluent

    9
    toxicity testing, oil and grease testing, and the measurement of mercury in water. The Board has
    incorporated 40 C.F.R. 136 by reference in Section 720.111 of the hazardous waste rules. Only one
    set of the testing methods amendments purports to affect the hazardous waste system; that is the
    May 14, 1999 oil and grease testing methods amendment. Persons interested in the details of the
    federal amendments should refer to the appropriate
    Federal Register
    notice cited above.
    The Board has incorporated the federal amendments without deviation. We have updated the
    version of 40 C.F.R. 136 incorporated by reference by adding the three cited
    Federal Register
    notices
    to the incorporation. The Board has included all three notices without regard to whether the individual
    methods updated or added by USEPA are actually used to achieve or demonstrate compliance under
    the RCRA Subtitle C regulatory scheme.
    The Board requested public comment on the update to the version of 40 C.F.R. 136
    incorporated by reference for the purposes of the Illinois RCRA Subtitle C hazardous waste regulatory
    program. We received no comments on this aspect of the proposed amendments in response to our
    request, and have adopted the amendments as proposed.
    Discussion of Miscellaneous Other Amendments not Federally Driven
    The tables beginning below list numerous corrections and amendments that are not based on
    current federal amendments. The first table (beginning immediately below) includes deviations made in
    the September 23, 1999 proposal for public comment from the verbatim text of the federal
    amendments. The second table (beginning below on page 12 of this opinion) contains corrections and
    clarifications that the Board made in the base text involved in this proposal. The amendments listed in
    this second table are not directly derived from the current federal amendments. Some of the entries in
    these tables are discussed further in appropriate segments of the general discussion beginning at page
    five of this opinion.
    The third table (beginning below on page 14 of this opinion) contains changes made, based on
    public comments received, to the text of the September 23, 1999 proposal for public comment. The
    third table indicates the affected provision of the rules, the source of the revision, and the nature of the
    revision. The fourth table (beginning below on page 14 of this opinion) contains those suggested
    changes that the Board has not made to the text. The fourth table indicates the affected provision, the
    source and nature of the suggestion for change, and the reasons the Board chose not to make the
    change.

    HISTORY OF RCRA SUBTITLE C AND UIC ADOPTION
    ILLINOIS ENVIRONMENTAL PROTECTION AGENCY OR BOARD ACTION
    EDITORIAL CONVENTIONS
    The Board appends the following three discussions to this opinion. The first is a summary
    history of the Illinois RCRA Subtitle C and UIC programs. It lists all Board actions taken to adopt and
    maintain these programs since their inception. 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 to date. The second is a discussion of how the Board codifies requirements that
    call for state determinations, such as exemptions or exceptions. The third discussion relates to our use
    of language in the codification of identical-in-substance rules. We intend these as reference aids for
    interested persons in the regulated community.
    History of RCRA Subtitle C and State Hazardous Waste Rules Adoption
    The Board has adopted and amended the Resource Conservation and Recovery Act (RCRA)
    Subtitle C hazardous waste rules in several dockets. The dockets captioned Proposed Regulations for
    “RCRA” (Chapter 7 and Chapter 9) (September 16, 1981, and February 4, 1982), R81-22, and
    Amendments to Phase I, RCRA Rules (January 13, 1983), R82-18, dealt with the Phase I RCRA
    Subtitle C regulations. The Board adopted RCRA Subtitle C Phase II regulations in Parts 703 and 724
    in dockets Phase II, RCRA Rules (July 26, 1983), R82-19, and Technical Correction to Phase II
    RCRA Rules (December 15, 1983), R83-24. USEPA reviewed and authorized the Illinois Phase I and
    Phase II regulations. The entire listing of all RCRA Subtitle C identical-in-substance rulemakings
    follows. A listing of federal authorizations of the Illinois program to date, as noticed in the
    Federal
    Register
    , appears at the end of this historical summary of the Illinois hazardous waste program.

    Petition of Cabot Corporation for an Adjusted Standard (May 19, 1994),
    AS 91-10. (Dismissed; secondary containment for tanks.)

    Adm. Code 721.104(b)(7)(U) (August 8, 1991), R91-11. (Filed by Big River
    Zinc Corp.)
    The Board has also adopted requirements limiting and restricting the landfilling of liquid
    hazardous wastes, hazardous wastes containing halogenated compounds, and hazardous wastes
    generally:
    R81-25
    Proposal for Adoption of Sanitary landfill Regulation, Rule 310: Special

    District Court of Appeals. Citizens for a Better Environment v. PCB, 152 Ill. App. 3d 105, 504
    N.E.2d 166 (1st Dist. 1987).
    Public Act 90-502, effective August 19, 1997, amended Section 22.23a of the Act to require
    the Board to designate high intensity discharge lamps and fluorescent lamps as a category of universal

    24
    waste based on a proposal to be filed by the Illinois Environmental Protection Agency (IEPA). The
    Board adopted such amendments to the Illinois hazardous waste rules on April 2, 1998, effective
    April 15, 1998. Amendments of 35 Ill. Adm. Code 703, 720, 721, 724, 725, 728, and 733
    (Standards For Universal Waste Management) (April 2, 1998), R98-12.

    28
    USEPA authorized the Illinois UIC program on March 3, 1984, at 49 Fed. Reg. 3991
    (February 1, 1984); codified that approval as 40 C.F.R. 147, Subpart O, at 49 Fed. Reg. 20197
    (May 11, 1984); and amended the authorization at 53 Fed. Reg. 43087 (October 25, 1988) and 56
    Fed. Reg. 9414 (March 6, 1991).
    Illinois Environmental Protection IEPA or Board Action
    Section 7.2(a)(5) of the Act requires the Board to specify for which portions of the program
    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 IEPA to consider. In determining the general division of authority between the IEPA
    and the Board, the following factors should be considered:
    1.
    Whether the person making the decision is applying a Board regulation, or taking action
    contrary to (“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 IEPA 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 site-specific
    rulemaking). There often are differences in the nomenclature for these decisions between the USEPA
    and Board regulations.

    Adopted Rule. Final Order.
    ORDER OF THE BOARD (by E.Z. Kezelis):
    Under Sections 7.2 and 22.4(a) of the Environmental Protection Act (Act) (415 ILCS 5/7.2
    and 22.4(a) (1998)), the Board today adopts amendments to the Illinois regulations that are “identical in
    substance” to hazardous waste regulations that the United States Environmental Protection Agency
    (USEPA) adopted to implement Subtitle C of the federal Resource Conservation and Recovery Act of
    1976 (RCRA Subtitle C) (42 U.S.C. §§ 6921
    et seq
    . (1998)). The nominal timeframe of this docket
    includes federal RCRA Subtitle C amendments that USEPA adopted in the period January 1, 1999,
    through June 30, 1999.

    30
    Sections 7.2 and 22.4(a) provide for quick adoption of regulations that are identical in
    substance to federal regulations that USEPA adopts to implement Sections 3001 through 3005 of
    RCRA (42 U.S.C. §§ 6921-6925 (1998)). Section 22.4(a) also provides that Title VII of the Act and
    Section 5 of the Administrative Procedure Act (APA) (5 ILCS 100/5-35 and 5-40 (1998)) do not
    apply to the Board’s adoption of identical-in-substance regulations. The federal RCRA Subtitle C
    regulations are found at 40 C.F.R. 260 through 266, 268, 270, 271, 273, and 279.
    This order is supported by an opinion that the Board also adopts today. The Board will wait 30
    days for USEPA to review the amendments, as provided in the agreement between USEPA and the
    State of Illinois relating to federal authorization of the State program, in order to allow USEPA an
    additional opportunity to review the amendments before they become effective. We will then file the
    amendments with the Secretary of State and submit Notices of Adopted Amendments for publication in
    the
    Illinois Register
    . The complete text of the adopted amendments follows.
    IT IS SO ORDERED.
    I, Dorothy M. Gunn, Clerk of the Illinois Pollution Control Board, do hereby certify that the
    above order was adopted on the 2nd day of December 1999 by a vote of 6-0.

    2)
    A generator that accumulates either hazardous waste or acutely hazardous
    waste listed in 35 Ill. Adm. Code 721.133(e) in excess of the amounts listed in
    subsection (c)(1) of this Section at or near any point of generation must, with
    respect to that amount of excess waste, comply within three days with
    subsection (a) of this Section or other applicable provisions of this Chapter.
    During the three day period the generator must continue to comply with
    subsection (c)(1) of this Section. The generator must mark the container
    holding the excess accumulation of hazardous waste with the date the excess
    amount began accumulating.
    d)
    A generator that generates greater than 100 kilograms but less than 1000 kilograms of
    hazardous waste in a calendar month may accumulate hazardous waste on-site for 180
    days or less without a permit or without having interim status provided that the following
    conditions are fulfilled:
    1)
    The quantity of waste accumulated on-site never exceeds 6000 kilograms;
    2)
    The generator complies with the requirements of 35 Ill. Adm. Code

    5)
    The generator complies with the following requirements:
    A)
    At all times there must be at least one employee either on the premises
    or on call (i.e., available to respond to an emergency by reaching the
    facility within a short period of time) with the responsibility for
    coordinating all emergency response measures specified in subsection
    (d)(5)(D) of this Section. The employee is the emergency coordinator.
    B)
    The generator shall post the following information next to the telephone:
    i)
    The name and telephone number of the emergency coordinator;
    ii)

    SUBPART AA: AIR EMISSION STANDARDS FOR PROCESS VENTS
    Section 724.931
    Definitions
    As used in this Subpart, all terms not defined in the this Subpart have the meaning given them in the
    Resource Conservation and Recovery Act and 35 Ill. Adm. Code 720 through 726.
    “Air stripping operation” is means a desorption operation employed to transfer one or
    more volatile components from a liquid mixture into a gas (air) either with or without the
    application of heat to the liquid. Packed towers, spray towers and bubble-cap, sieve,
    or valve-type plate towers are among the process configurations used for contacting the
    air and a liquid.
    “Bottoms receiver” means a container or tank used to receive and collect the heavier
    bottoms fractions of the distillation feed stream that remain in the liquid phase.
    “Btu” means British thermal unit.
    “Closed-vent system” means a system that is not open to the atmosphere and that is
    composed of piping, connections, and, if necessary, flow-inducing devices that transport
    gas or vapor from a piece or pieces of equipment to a control device.

    54
    “Condenser” means a heat-transfer device that reduces a thermodynamic fluid from its
    vapor phase to its liquid phase.
    “Connector” means flanged, screwed, welded or other joined fittings used to connect
    two pipelines or a pipeline and a piece of equipment. For the purposes of reporting and
    recordkeeping, “connector” means flanged fittings that are not covered by insulation or
    other materials that prevent location of the fittings.
    “Continuous recorder” means a data-recording device recording an instantaneous data
    value at least once every 15 minutes.
    “Control device” means an enclosed combustion device, vapor recovery system, or
    flare. Any device the primary function of which is the recovery or capture of solvents or
    other organics for use, reuse, or sale (e.g., a primary condenser on a solvent recovery
    unit) is not a control device.
    “Control device shutdown” means the cessation of operation of a control device for any
    purpose.
    “Distillate receiver” means a container or tank used to receive and collect liquid material
    (condensed) from the overhead condenser of a distillation unit and from which the
    condensed liquid is pumped to larger storage tanks or other process units.
    “Distillation operation” means an operation, either batch or continuous, separating one
    or more feed stream(s) into two or more exit streams, each exit stream having
    component concentrations different from those in the feed stream(s). The separation is
    achieved by the redistribution of the components between the liquid and vapor phase as
    they approach equilibrium within the distillation unit.
    “Double block and bleed system” means two block valves connected in series with a
    bleed valve or line that can vent the line between the two block valves.
    “Equipment” means each valve, pump, compressor, pressure relief device, sampling
    connection system, open-ended valve or line, or flange or other connector, and any
    control devices or systems required by this Subpart.
    “First attempt at repair” means to take rapid action for the purpose of stopping or
    reducing leakage of organic material to the atmosphere using best practices.
    “Flame zone” means the portion of the combustion chamber in a boiler occupied by the
    flame envelope.
    “Flow indicator” means a device that indicates whether gas flow is present in a vent

    55
    stream.
    “Fractionation operation” means a distillation operation or method used to separate a
    mixture of several volatile components of different boiling points in successive stages,
    each stage removing from the mixture some proportion of one of the components.
    “ft” means foot.
    “h” means hour.
    “Hazardous waste management unit shutdown” means a work practice or operational
    procedure that stops operation of a hazardous waste management unit or part of a
    hazardous waste management unit. An unscheduled work practice or operational
    procedure that stops operation of a hazardous waste management unit or part of a
    hazardous waste management unit for less than 24 hours is not a hazardous waste
    management unit shutdown. The use of spare equipment and technically feasible
    bypassing of equipment without stopping operation are not hazardous waste
    management unit shutdowns.
    “Hot well” means a container for collecting condensate as in a steam condenser serving
    a vacuum-jet or steam-jet ejector.
    “In gas-vapor service” means that the piece of equipment contains or contacts a
    hazardous waste stream that is in the gaseous state at operating conditions.
    “In heavy liquid service” means that the piece of equipment is not in gas-vapor service
    or in light liquid service.
    “In light liquid service” means that the piece of equipment contains or contacts a waste
    stream where the vapor pressure of one or more of the organic components in the
    stream is greater than 0.3 kilopascals (kPa) at 20° C, the total concentration of the pure
    organic components having a vapor pressure greater than 0.3 kPa at 20° C is equal to
    or greater than 20 percent by weight, and the fluid is a liquid at operating conditions.
    “In situ sampling systems” means nonextractive samplers or in-line samplers.
    “In vacuum service” means that equipment is operating at an internal pressure that is at
    least 5 kPa below ambient pressure.
    “Kg” means kilogram.
    “kPa” means kilopascals.

    56
    “lb” means pound.
    “m” means meter.
    “Mg” means Megagrams, or metric tonnes.
    “MJ” means Megajoules, or ten to the sixth Joules.
    “MW” means Megawatts.
    “Malfunction” means any sudden failure of a control device or a hazardous waste
    management unit or failure of a hazardous waste management unit to operate in a normal
    or usual manner, so that organic emissions are increased.
    “Open-ended valve or line” means any valve, except a pressure relief valves valve,
    having that has one side of the valve seat in contact with process fluid hazardous waste
    and one side open to the atmosphere, either directly or through open piping.
    “ppmv” means parts per million by volume.
    “ppmw” means parts per million by weight.
    “Pressure release” means the emission of materials resulting from the system pressure
    being greater than the set pressure of the pressure relief device.
    “Process heater” means a device that transfers heat liberated by burning fuel to fluids
    contained in tubes, including all fluids except water that are heated to produce steam.
    “Process vent” means any open-ended pipe or stack that is vented to the atmosphere
    either directly, through a vacuum-producing system, or through a tank (e.g., distillate
    receiver, condenser, bottoms receiver, surge control tank, separator tank, or hot well)
    associated with hazardous waste distillation, fractionation, thin-film evaporation, solvent
    extraction, or air or steam stripping operations.
    “Repaired” means that equipment is adjusted, or otherwise altered, to eliminate a leak.
    “s” means second.
    “Sampling connection system” means an assembly of equipment within a process or
    waste management unit that is used during periods of representative operation to take
    samples of the process or waste fluid. Equipment that is used to take non-routine grab
    samples is not considered a sampling connection system.

    57

    or between the perimeter of the opening and the closure device;
    or
    ii)
    The opening or manifold system is connected by a closed-vent
    system that is vented to a control device. The control device
    must remove or destroy organics in the vent stream, and it must
    be operating whenever hazardous waste is managed in the tank,
    except as provided for in subsection (c)(2)(E) of this Section.
    D)
    The fixed roof and its closure devices must be made of suitable
    materials that will minimize exposure of the hazardous waste to the
    atmosphere, to the extent practical, and will maintain the integrity of the
    fixed roof and closure devices throughout their intended service life.
    Factors to be considered when selecting the materials for and designing
    the fixed roof and closure devices must include the following: the
    organic vapor permeability; the effects of any contact with the
    hazardous waste or its vapors managed in the tank; the effects of
    outdoor exposure to wind, moisture, and sunlight; and the operating
    practices used for the tank on which the fixed roof is installed.
    E)
    The control device operated pursuant to subsection (c)(2)(C) of this
    Section needs not remove or destroy organics in the vent stream under
    the following conditions:

    operator shall promptly secure the closure device in the closed
    position or reinstall the cover, as applicable, and resume
    operation of the control device; and
    ii)
    During periods of routine inspection, maintenance, or other
    activities needed for normal operations, and for removal of
    accumulated sludge or other residues from the bottom of the
    tank.
    BOARD NOTE: Subsections (c)(2)(E)(i) and (c)(2)(E)(ii) are derived
    from 40 CFR 264.1084(c)(2)(iii)(B)(
    1
    ) and (c)(2)(iii)(B)(
    2
    ), which the
    Board has codified here to comport with Illinois Administrative Code

    65
    format requirements.
    3)
    Whenever a hazardous waste is in the tank, the fixed roof must be installed with
    each closure device secured in the closed position, except as follows:
    A)
    Opening of closure devices or removal of the fixed roof is allowed at
    the following times:
    i)
    To provide access to the tank for performing routine inspection,
    maintenance, or other activities needed for normal operations.
    Examples of such activities include those times when a worker
    needs to open a port to sample the liquid in the tank, or when a
    worker needs to open a hatch to maintain or repair equipment.
    Following completion of the activity, the owner or operator shall
    promptly secure the closure device in the closed position or
    reinstall the cover, as applicable, to the tank.
    ii)
    To remove accumulated sludge or other residues from the
    bottom of the tank.
    B)
    Opening of a spring-loaded pressure-vacuum relief valve, conservation
    vent, or similar type of pressure relief device which that vents to the
    atmosphere is allowed during normal operations for the purpose of
    maintaining the tank internal pressure in accordance with the tank design
    specifications. The device must be designed to operate with no
    detectable organic emissions when the device is secured in the closed
    position. The settings at which the device opens must be established
    such so that the device remains in the closed position whenever the tank
    internal pressure is within the internal pressure operating range
    determined by the owner or operator based on the tank manufacturer
    recommendations, applicable regulations, fire protection and prevention
    codes, standard engineering codes and practices, or other requirements
    for the safe handling of flammable, ignitable, explosive, reactive, or
    hazardous materials. Examples of normal operating conditions that may
    require these devices to open are during those times when the tank
    internal pressure exceeds the internal pressure operating range for the
    tank as a result of loading operations or diurnal ambient temperature
    fluctuations.
    C)
    Opening of a safety device, as defined in 35 Ill. Adm. Code 725.981, is

    C)
    Prior to each inspection required by subsection (f)(3)(A) or (f)(3)(B) of
    this Section, the owner or operator shall notify the Agency in advance
    of each inspection to provide the Agency with the opportunity to have

    74
    an observer present during the inspection. The owner or operator shall
    notify the Agency of the date and location of the inspection as follows:
    i)
    Prior to each inspection to measure external floating roof seal
    gaps as required under subsection (f)(3)(A) of this Section,
    written notification must be prepared and sent by the owner or
    operator so that it is received by the Agency at least 30
    calendar days before the date the measurements are scheduled
    to be performed.
    ii)
    Prior to each visual inspection of an external floating roof in a
    tank that has been emptied and degassed, written notification
    must be prepared and sent by the owner or operator so that it is
    received by the Agency at least 30 calendar days before refilling
    the tank, except when an inspection is not planned as provided
    for in subsection (f)(3)(C)(iii) of this Section.
    iii)
    When a visual inspection is not planned and the owner or
    operator could not have known about the inspection 30
    calendar days before refilling the tank, the owner or operator
    shall notify the Agency as soon as possible, but no later than
    seven calendar days before refilling of the tank. This notification
    may be made by telephone and immediately followed by a
    written explanation for why the inspection is unplanned.
    Alternatively, written notification, including the explanation for
    the unplanned inspection, may be sent so that it is received by
    the Agency at least seven calendar days before refilling the tank.
    D)
    Procedure for determining the total surface area of gaps in the primary
    seal and the secondary seal:
    i)
    The seal gap measurements must be performed at one or more
    floating roof levels when the roof is floating off the roof
    supports.
    ii)
    Seal gaps, if any, must be measured around the entire perimeter
    of the floating roof in each place where a 0.32 cm (0.125 in)
    diameter uniform probe passes freely (without forcing or binding
    against the seal) between the seal and the wall of the tank and
    measure the circumferential distance of each such location.
    iii)
    For a seal gap measured under subsection (f)(3) of this Section,
    the gap surface area must be determined by using probes of

    75
    various widths to measure accurately the actual distance from
    the tank wall to the seal and multiplying each such width by its
    respective circumferential distance.
    iv)
    The total gap area must be calculated by adding the gap surface
    areas determined for each identified gap location for the primary
    seal and the secondary seal individually, and then dividing the
    sum for each seal type by the nominal diameter of the tank.
    These total gap areas for the primary seal and secondary seal
    are then compared to the respective standards for the seal type,
    as specified in subsection (f)(1)(B) of this Section.
    BOARD NOTE: Subsections (f)(3)(D)(i) through (f)(3)(D)(iv) are
    derived from 40 CFR 264.1084(f)(3)(i)(D)(1) through (f)(3)(i)(D)(4),
    which the Board has codified here to comport with Illinois
    Administrative Code format requirements.
    4)

    Level 2 standards specified in subsection (d) of this Section.
    2)
    When a container having a design capacity greater than 0.1 m
    3
    (26 gal) is used
    for treatment of a hazardous waste by a waste stabilization process, the owner
    or operator shall control air pollutant emissions from the container in
    accordance with the Container Level 3 standards specified in subsection (e) of
    this Section at those times during the waste stabilization process when the
    hazardous waste in the container is exposed to the atmosphere.
    c)
    Container Level 1 standards.
    1)
    A container using Container Level 1 controls is one of the following:
    A)
    A container that meets the applicable U.S. Department of
    Transportation (USDOT) regulations on packaging hazardous materials
    for transportation, as specified in subsection (f) of this Section.
    B)
    A container equipped with a cover and closure devices that form a
    continuous barrier over the container openings so that when the cover
    and closure devices are secured in the closed position there are no
    visible holes, gaps, or other open spaces into the interior of the
    container. The cover may be a separate cover installed on the container
    (e.g., a lid on a drum or a suitably secured tarp on a roll-off box) or
    may be an integral part of the container structural design (e.g., a
    “portable tank” or bulk cargo container equipped with a screw-type
    cap).
    C)
    An open-top container in which an organic-vapor suppressing barrier is
    placed on or over the hazardous waste in the container such so that no
    hazardous waste is exposed to the atmosphere. One example of such a
    barrier is application of a suitable organic-vapor suppressing foam.
    2)
    A container used to meet the requirements of subsection (c)(1)(B) or (c)(1)(C)
    of this Section must be equipped with covers and closure devices, as applicable
    to the container, that are composed of suitable materials to minimize exposure
    of the hazardous waste to the atmosphere and to maintain the equipment
    integrity, for as long as it is in service. Factors to be considered in selecting the
    materials of construction and designing the cover and closure devices must
    include the following: the organic vapor permeability; the effects of contact with
    the hazardous waste or its vapor managed in the container; the effects of
    outdoor exposure of the closure device or cover material to wind, moisture, and
    sunlight; and the operating practices for which the container is intended to be
    used.

    82
    3)
    Whenever a hazardous waste is in a container using Container Level 1 controls,
    the owner or operator shall install all covers and closure devices for the
    container, as applicable to the container, and secure and maintain each closure
    device in the closed position except as follows:
    A)
    Opening of a closure device or cover is allowed for the purpose of
    adding hazardous waste or other material to the container as follows:
    i)
    In the case when the container is filled to the intended final level
    in one continuous operation, the owner or operator shall
    promptly secure the closure devices in the closed position and
    install the covers, as applicable to the container, upon
    conclusion of the filling operation.
    ii)
    In the case when discrete quantities or batches of material
    intermittently are added to the container over a period of time,
    the owner or operator shall promptly secure the closure devices
    in the closed position and install covers, as applicable to the
    container, upon either the container being filled to the intended
    final level; the completion of a batch loading after which no
    additional material will be added to the container within 15
    minutes; the person performing the loading operation leaving the
    immediate vicinity of the container; or the shutdown of the
    process generating the material being added to the container,
    whichever condition occurs first.
    B)
    Opening of a closure device or cover is allowed for the purpose of
    removing hazardous waste from the container as follows:
    i)
    For the purpose of meeting the requirements of this Section, an
    empty container, as defined in 35 Ill. Adm. Code 721.107(b),
    may be open to the atmosphere at any time (i.e., covers and
    closure devices are not required to be secured in the closed
    position on an empty container).
    ii)
    In the case when discrete quantities or batches of material are
    removed from the container but the container does not meet the
    conditions to be an empty container as defined in 35 Ill. Adm.
    Code 721.107(b), the owner or operator shall promptly secure
    the closure devices in the closed position and install covers, as
    applicable to the container, upon the completion of a batch
    removal after which no additional material will be removed from

    83
    the container within 15 minutes or the person performing the
    unloading operation leaves the immediate vicinity of the
    container, whichever condition occurs first.
    C)
    Opening of a closure device or cover is allowed when access inside the
    container is needed to perform routine activities other than transfer of
    hazardous waste. Examples of such activities include those times when
    a worker needs to open a port to measure the depth of or sample the
    material in the container, or when a worker needs to open a manhole
    hatch to access equipment inside the container. Following completion
    of the activity, the owner or operator shall promptly secure the closure
    device in the closed position or reinstall the cover, as applicable to the
    container.
    D)
    Opening of a spring-loaded pressure-vacuum relief valve, conservation
    vent, or similar type of pressure relief device which that vents to the
    atmosphere is allowed during normal operations for the purpose of
    maintaining the internal pressure of the container in accordance with the
    container design specifications. The device must be designed to
    operate with no detectable organic emissions when the device is
    secured in the closed position. The settings at which the device opens
    must be established such so that the device remains in the closed
    position whenever the internal pressure of the container is within the
    internal pressure operating range determined by the owner or operator
    based on container manufacturer recommendations, applicable
    regulations, fire protection and prevention codes, standard engineering
    codes and practices, or other requirements for the safe handling of
    flammable, ignitable, explosive, reactive, or hazardous materials.
    Examples of normal operating conditions that may require these devices
    to open are during those times when the internal pressure of the
    container exceeds the internal pressure operating range for the container
    as a result of loading operations or diurnal ambient temperature
    fluctuations.
    E)
    Opening of a safety device, as defined in 35 Ill. Adm. Code 725.981, is
    allowed at any time conditions require doing so to avoid an unsafe
    condition.
    4)
    The owner or operator of containers using Container Level 1 controls shall
    inspect the containers and their covers and closure devices as follows:
    A)
    In the case when a hazardous waste already is in the container at the
    time the owner or operator first accepts possession of the container at

    84
    the facility and the container is not emptied within 24 hours after the
    container is accepted at the facility (i.e., it does not meet the conditions
    for an empty container as specified in 35 Ill. Adm. Code 721.107(b)),
    the owner or operator shall visually inspect the container and its cover
    and closure devices to check for visible cracks, holes, gaps, or other
    open spaces into the interior of the container when the cover and
    closure devices are secured in the closed position. The container visual
    inspection must be conducted on or before the date on which the
    container is accepted at the facility (i.e., the date when the container
    becomes subject to the Subpart CC container standards). For the
    purposes of this requirement, the date of acceptance is the date of
    signature that the facility owner or operator enters on Item 20 of the
    Uniform Hazardous Waste Manifest incorporated by reference in 35 Ill.
    Adm. Code 722.Appendix A (USEPA Forms 8700-22 and 8700-
    22A), as required under Section 724.171. If a defect is detected, the
    owner or operator shall repair the defect in accordance with the
    requirements of subsection (c)(4)(C) of this Section.
    B)
    In the case when a container used for managing hazardous waste
    remains at the facility for a period of one year or more, the owner or
    operator shall visually inspect the container and its cover and closure
    devices initially and thereafter, at least once every 12 months, to check
    for visible cracks, holes, gaps, or other open spaces into the interior of
    the container when the cover and closure devices are secured in the
    closed position. If a defect is detected, the owner or operator shall
    repair the defect in accordance with the requirements of subsection
    (c)(4)(C) of this Section.
    C)
    When a defect is detected for the container, cover, or closure devices,
    the owner or operator shall make first efforts at repair of the defect no
    later than 24 hours after detection and repair must be completed as
    soon as possible but no later than five calendar days after detection. If
    repair of a defect cannot be completed within five calendar days, then
    the hazardous waste must be removed from the container and the
    container must not be used to manage hazardous waste until the defect
    is repaired.
    5)
    The owner or operator shall maintain at the facility a copy of the procedure
    used to determine that containers with capacity of 0.46 m
    3
    (120 gal) or greater,
    which do not meet applicable DOT regulations, as specified in subsection (f) of
    this Section, are not managing hazardous waste in light material service.
    d)
    Container Level 2 standards.

    85
    1)
    A container using Container Level 2 controls is one of the following:
    A)

    A container that has been demonstrated within the preceding 12 months
    to be vapor-tight by using 40 CFR 60, appendix A, Method 27,
    incorporated by reference in 35 Ill. Adm. Code 720.111, in
    accordance with the procedure specified in subsection (h) of this
    Section.
    2)
    Transfer of hazardous waste in or out of a container using Container Level 2
    controls must be conducted in such a manner as to minimize exposure of the
    hazardous waste to the atmosphere, to the extent practical, considering the
    physical properties of the hazardous waste and good engineering and safety
    practices for handling flammable, ignitable, explosive, reactive, or other
    hazardous materials. Examples of container loading procedures that the
    USEPA considers to meet the requirements of this subsection (d)(2) include
    using any one of the following: a submerged-fill pipe or other submerged-fill
    method to load liquids into the container; a vapor-balancing system or a vapor-
    recovery system to collect and control the vapors displaced from the container
    during filling operations; or a fitted opening in the top of a container through
    which the hazardous waste is filled and subsequently purging the transfer line
    before removing it from the container opening.
    3)
    Whenever a hazardous waste is in a container using Container Level 2 controls,
    the owner or operator shall install all covers and closure devices for the
    container, and secure and maintain each closure device in the closed position,
    except as follows:
    A)
    Opening of a closure device or cover is allowed for the purpose of
    adding hazardous waste or other material to the container as follows:
    i)
    In the case when the container is filled to the intended final level
    in one continuous operation, the owner or operator shall
    promptly secure the closure devices in the closed position and
    install the covers, as applicable to the container, upon

    86
    conclusion of the filling operation.
    ii)
    In the case when discrete quantities or batches of material
    intermittently are added to the container over a period of time,
    the owner or operator shall promptly secure the closure devices
    in the closed position and install covers, as applicable to the
    container, upon either the container being filled to the intended
    final level; the completion of a batch loading after which no
    additional material will be added to the container within 15
    minutes; the person performing the loading operation leaving the
    immediate vicinity of the container; or the shutdown of the
    process generating the material being added to the container,
    whichever condition occurs first.
    B)
    Opening of a closure device or cover is allowed for the purpose of
    removing hazardous waste from the container as follows:
    i)
    For the purpose of meeting the requirements of this Section, an
    empty container as defined in 35 Ill. Adm. Code 721.107(b)
    may be open to the atmosphere at any time (i.e., covers and
    closure devices are not required to be secured in the closed
    position on an empty container).
    ii)
    In the case when discrete quantities or batches of material are
    removed from the container but the container does not meet the
    conditions to be an empty container as defined in 35 Ill. Adm.
    Code 721.107(b), the owner or operator shall promptly secure
    the closure devices in the closed position and install covers, as
    applicable to the container, upon the completion of a batch
    removal after which no additional material will be removed from
    the container within 15 minutes or the person performing the
    unloading operation leaves the immediate vicinity of the
    container, whichever condition occurs first.
    C)
    Opening of a closure device or cover is allowed when access inside the
    container is needed to perform routine activities other than transfer of
    hazardous waste. Examples of such activities include those times when
    a worker needs to open a port to measure the depth of or sample the
    material in the container, or when a worker needs to open a manhole
    hatch to access equipment inside the container. Following completion
    of the activity, the owner or operator shall promptly secure the closure
    device in the closed position or reinstall the cover, as applicable to the
    container.

    87
    D)
    Opening of a spring-loaded, pressure-vacuum relief valve, conservation
    vent, or similar type of pressure relief device which that vents to the
    atmosphere is allowed during normal operations for the purpose of
    maintaining the internal pressure of the container in accordance with the
    container design specifications. The device must be designed to operate
    with no detectable organic emission when the device is secured in the
    closed position. The settings at which the device opens must be
    established such so that the device remains in the closed position
    whenever the internal pressure of the container is within the internal
    pressure operating range determined by the owner or operator based
    on container manufacturer recommendations, applicable regulations, fire
    protection and prevention codes, standard engineering codes and
    practices, or other requirements for the safe handling of flammable,
    ignitable, explosive, reactive, or hazardous materials. Examples of
    normal operating conditions that may require these devices to open are
    during those times when the internal pressure of the container exceeds
    the internal pressure operating range for the container as a result of
    loading operations or diurnal ambient temperature fluctuations.
    E)
    Opening of a safety device, as defined in 35 Ill. Adm. Code 725.981, is
    allowed at any time conditions require doing so to avoid an unsafe
    condition.
    4)
    The owner or operator of containers using Container Level 2 controls shall
    inspect the containers and their covers and closure devices as follows:
    A)
    In the case when a hazardous waste already is in the container at the
    time the owner or operator first accepts possession of the container at
    the facility and the container is not emptied within 24 hours after the
    container is accepted at the facility (i.e., it does not meet the conditions
    for an empty container as specified in 35 Ill. Adm. Code 721.107(b)),
    the owner or operator shall visually inspect the container and its cover
    and closure devices to check for visible cracks, holes, gaps, or other
    open spaces into the interior of the container when the cover and
    closure devices are secured in the closed position. The container visual
    inspection must be conducted on or before the date on which the
    container is accepted at the facility (i.e., the date when the container
    becomes subject to the Subpart CC container standards). For the
    purposes of this requirement, the date of acceptance is the date of
    signature that the facility owner or operator enters on Item 20 of the
    Uniform Hazardous Waste Manifest incorporated by reference in the
    appendix to 40 CFR 262 (USEPA Forms 8700-22 and 8700-22A),

    88
    as required under Section 724.171. If a defect is detected, the owner
    or operator shall repair the defect in accordance with the requirements
    of subsection (d)(4)(C) of this Section.
    B)
    In the case when a container used for managing hazardous waste
    remains at the facility for a period of one year or more, the owner or
    operator shall visually inspect the container and its cover and closure
    devices initially and thereafter, at least once every 12 months, to check
    for visible cracks, holes, gaps, or other open spaces into the interior of
    the container when the cover and closure devices are secured in the
    closed position. If a defect is detected, the owner or operator shall
    repair the defect in accordance with the requirements of subsection
    (d)(4)(C) of this Section.
    C)
    When a defect is detected for the container, cover, or closure devices,
    the owner or operator shall make first efforts at repair of the defect no
    later than 24 hours after detection, and repair must be completed as
    soon as possible but no later than five calendar days after detection. If
    repair of a defect cannot be completed within five calendar days, then
    the hazardous waste must be removed from the container and the
    container must not be used to manage hazardous waste until the defect
    is repaired.
    e)

    1)
    A container using Container Level 3 controls is one of the following:
    A)
    A container that is vented directly through a closed-vent system to a
    control device in accordance with the requirements of subsection
    (e)(2)(B) of this Section.
    B)
    A container that is vented inside an enclosure which is exhausted
    through a closed-vent system to a control device in accordance with the
    requirements of subsections (e)(2)(A) and (e)(2)(B) of this Section.
    2)
    The owner or operator shall meet the following requirements, as applicable to
    the type of air emission control equipment selected by the owner or operator:
    A)
    The container enclosure must be designed and operated in accordance
    with the criteria for a permanent total enclosure as specified in
    “Procedure T--Criteria for and Verification of a Permanent or
    Temporary Total Enclosure” under 40 CFR 52.741, appendix B,
    incorporated by reference in 35 Ill. Adm. Code 720.111. The

    89
    enclosure may have permanent or temporary openings to allow worker
    access; passage of containers through the enclosure by conveyor or
    other mechanical means; entry of permanent mechanical or electrical
    equipment; or direct airflow into the enclosure. The owner or operator
    shall perform the verification procedure for the enclosure as specified in
    Section 5.0 to “Procedure T--Criteria for and Verification of a
    Permanent or Temporary Total Enclosure” initially when the enclosure is
    first installed and, thereafter, annually.
    B)
    The closed-vent system and control device must be designed and
    operated in accordance with the requirements of Section 724.987.
    3)
    Safety devices, as defined in 35 Ill. Adm. Code 725.981, may be installed and
    operated as necessary on any container, enclosure, closed-vent system, or
    control device used to comply with the requirements of subsection (e)(1) of this
    Section.
    4)
    Owners and operators using Container Level 3 controls in accordance with the
    provisions of this Subpart shall inspect and monitor the closed-vent systems and
    control devices as specified in Section 724.987.
    5)
    Owners and operators that use Container Level 3 controls in accordance with
    the provisions of this Subpart shall prepare and maintain the records specified in
    Section 724.989(d).
    6) The transfer of hazardous waste into or out of a container using Container Level
    3 controls must be conducted in such a manner as to minimize exposure of the
    hazardous waste to the atmosphere, to the extent practical considering the
    physical properties of the hazardous waste and good engineering and safety
    practices for handling flammable, ignitable, explosive, reactive, or other
    hazardous materials. Examples of container loading procedures that USEPA
    considers to meet the requirements of this subsection (e)(6) include using any
    one of the following: the use of a submerged-fill pipe or other submerged-fill
    method to load liquids into the container; the use of a vapor-balancing system or
    a vapor-recovery system to collect and control the vapors displaced from the
    container during filling operations; or the use of a fitted opening in the top of a
    container through which the hazardous waste is filled and subsequently purging
    the transfer line before removing it from the container opening.
    f)
    For the purpose of compliance with subsection (c)(1)(A) or (d)(1)(A) of this Section,
    containers must be used that meet the applicable U.S. Department of Transportation
    (USDOT) regulations on packaging hazardous materials for transportation as follows:

    90
    1)
    The container meets the applicable requirements specified in 49 CFR 178,
    “Specifications for Packaging”, or 49 CFR 179, “Specifications for Tank
    Cars”, both incorporated by reference in 35 Ill. Adm. Code 720.111.
    2)
    Hazardous waste is managed in the container in accordance with the applicable

    and Packages”; and 49 CFR 180, “Continuing Qualification and Maintenance
    of Packagings”, each incorporated by reference in 35 Ill. Adm. Code 720.111.
    3)
    For the purpose of complying with this Subpart, no exceptions to the 49 CFR
    178 or 179 regulations are allowed, except as provided for in subsection (f)(4)
    of this Section.
    4)
    For a lab pack that is managed in accordance with the requirements of 49 CFR
    178, incorporated by reference in 35 Ill. Adm. Code 720.111, for the purpose
    of complying with this Subpart, an owner or operator may comply with the
    exceptions for combination packagings specified in 49 CFR 173.12(b).
    g)
    To determine compliance with the no detectable organic emissions requirement of
    subsection (d)(1)(B) of this Section, the procedure specified in Section 724.983(d)
    must be used.
    1)
    Each potential leak interface (i.e., a location where organic vapor leakage could
    occur) on the container, its cover, and associated closure devices, as applicable
    to the container, must be checked. Potential leak interfaces that are associated
    with containers include, but are not limited to, the following: the interface of the
    cover rim and the container wall; the periphery of any opening on the container
    or container cover and its associated closure device; and the sealing seat
    interface on a spring-loaded pressure-relief valve.
    2)
    The test must be performed when the container is filled with a material having a
    volatile organic concentration representative of the range of volatile organic
    concentrations for the hazardous wastes expected to be managed in this type of
    container. During the test, the container cover and closure devices must be
    secured in the closed position.
    h)
    Procedure for determining a container to be vapor-tight using Method 27 of 40 CFR
    60, appendix A for the purpose of complying with subsection (d)(1)(C) of this Section.
    1)
    The test must be performed in accordance with Method 27 of 40 CFR 60,

    91
    appendix A, incorporated by reference in 35 Ill. Adm. Code 720.111.
    2)
    A pressure measurement device must be used that has a precision of ± 2.5 mm
    (0.098 in) water and that is capable of measuring above the pressure at which
    the container is to be tested for vapor tightness.
    3)
    If the test results determined by Method 27 indicate that the container sustains a
    pressure change less than or equal to 750 Pascals (0.11 psig) within five
    minutes after it is pressurized to a minimum of 4,500 Pascals (0.65 psig), then
    the container is determined to be vapor-tight.

    equipped with and operating air emission controls in accordance with the
    requirements of an applicable federal Clean Air Act regulation codified under
    40 CFR 60, 61, or 63. For the purpose of complying with this subsection
    (b)(7), a tank for which the air emission control includes an enclosure, as
    opposed to a cover, must be in compliance with the enclosure and control
    device requirements of Section 725.985(i), except as provided in Section
    725.983(c)(5).
    8)
    A tank that has a process vent, as defined in 35 Ill. Adm. Code 725.931.
    c)
    For the owner and operator of a facility subject to this Subpart that has received a final
    RCRA permit prior to December 6, 1996, the following requirements apply:
    1)
    The requirements of 35 Ill. Adm. Code 724.Subpart CC must be incorporated
    into the permit when the permit is reissued, renewed, or modified in accordance
    with the requirements of 35 Ill. Adm. Code 703 and 705.
    2)
    Until the date when the permit is reissued, renewed, or modified in accordance
    with the requirements of 35 Ill. Adm. Code 703 and 705, the owner and

    100
    operator is subject to the requirements of this Subpart.
    d)
    The requirements of this Subpart, except for the recordkeeping requirements specified
    in Section 725.990(i), are stayed for a tank or container used for the management of
    hazardous waste generated by organic peroxide manufacturing and its associated
    laboratory operations, when the owner or operator of the unit meets all of the following
    conditions:
    1)
    The owner or operator identifies that the tank or container receives hazardous
    waste generated by an organic peroxide manufacturing process producing more
    than one functional family of organic peroxides or multiple organic peroxides
    within one functional family, that one or more of these organic peroxides could
    potentially undergo self-accelerating thermal decomposition at or below ambient
    temperatures, and that organic peroxides are the predominant products
    manufactured by the process. For the purposes of this subsection, “organic
    peroxide” means an organic compound that contains the bivalent -O-O-
    structure and which may be considered to be a structural derivative of hydrogen
    peroxide where one or both of the hydrogen atoms has been replaced by an
    organic radical.
    2)
    The owner or operator prepares documentation, in accordance with Section
    725.990(i), explaining why an undue safety hazard would be created if air
    emission controls specified in Sections 725.985 through 725.988 are installed
    and operated on the tanks and containers used at the facility to manage the
    hazardous waste generated by the organic peroxide manufacturing process or
    processes meeting the conditions of subsection (d)(1) of this Section.
    3)
    The owner or operator notifies the Agency in writing that hazardous waste
    generated by an organic peroxide manufacturing process or processes meeting
    the conditions of subsection (d)(1) of this Section are managed at the facility in
    tanks or containers meeting the conditions of subsection (d)(2) of this Section.
    The notification must state the name and address of the facility and be signed
    and dated by an authorized representative of the facility owner or operator.

    Section 725.984
    Waste Determination Procedures
    a)
    Waste determination procedure for volatile organic (VO) concentration of a hazardous
    waste at the point of waste origination.
    1)
    An owner or operator shall determine the average VO concentration at the
    point of waste origination for each hazardous waste placed in a waste

    101
    management unit exempted under the provisions of Section 725.983(c)(1) from
    using air emission controls in accordance with standards specified in Section
    725.985 through Section 725.988, as applicable to the waste management unit.
    A) An owner or operator shall make an initial determination of the average
    VO concentration of the waste stream before the first time any portion
    of the material in the hazardous waste stream is placed in a waste
    management unit exempted under the provisions of Section
    725.983(c)(1) from using air emission controls. Thereafter, an owner
    or operator shall make an initial determination of the average VO
    concentration of the waste stream for each averaging period that a
    hazardous waste is managed in the unit.
    B) An owner or operator shall perform a new waste determination
    whenever changes to the source generating the waste stream are
    reasonably likely to cause the average VO concentration of the
    hazardous waste to increase to a level that is equal to or greater than the
    VO concentration limits specified in Section 725.983(c)(1).
    2)
    For a waste determination that is required by subsection (a)(1) of this Section,
    the average VO concentration of a hazardous waste at the point of waste
    origination must be determined using either direct measurement, as specified in
    subsection (a)(3) of this Section, or by knowledge of the waste, as specified in
    subsection (a)(4) of this Section.
    3)
    Direct measurement to determine average VO concentration of a hazardous
    waste at the point of waste origination.
    A)
    Identification. The owner or operator shall identify and record the point
    of waste origination for the hazardous waste.
    B)
    Sampling. Samples of the hazardous waste stream must be collected at
    the point of waste origination in such a manner such that volatilization of
    organics contained in the waste and in the subsequent sample is
    minimized and an adequately representative sample is collected and
    maintained for analysis by the selected method.
    i)
    The averaging period to be used for determining the average
    VO concentration for the hazardous waste stream on a mass-
    weighted average basis must be designated and recorded. The
    averaging period can represent any time interval that the owner
    or operator determines is appropriate for the hazardous waste
    stream but must not exceed one year.

    102
    ii)
    A sufficient number of samples, but no fewer than four samples,
    must be collected for a hazardous waste determination. All of
    the samples for a given waste determination must be collected
    within a one-hour period. The average of the four or more
    sample results constitutes a waste determination for the waste
    stream. One or more waste determinations may be required to
    represent the complete range of waste compositions and
    quantities that occur during the entire averaging period due to
    normal variations in the operating conditions for the source or
    process generating the hazardous waste stream. Examples of
    such normal variations are seasonal variations in waste quantity
    or fluctuations in ambient temperature.
    iii)
    All samples must be collected and handled in accordance with
    written procedures prepared by the owner or operator and
    documented in a site sampling plan. This plan must describe the
    procedure by which representative samples of the hazardous
    waste stream are collected such so that a minimum loss of
    organics occurs throughout the sample collection and handling
    process, and by which sample integrity is maintained. A copy
    of the written sampling plan must be maintained on-site in the
    facility operating records. An example of an acceptable
    sampling plan includes a plan incorporating sample collection
    and handling procedures in accordance with the requirements
    specified in “Test Methods for Evaluating Solid Waste,
    Physical/Chemical Methods,” USEPA Publication SW-846,
    incorporated by reference in 35 Ill. Adm. Code 720.111, or in
    Method 25D in 40 CFR 60, appendix A, incorporated by
    reference in 35 Ill. Adm. Code 720.111.
    iv)
    Sufficient information, as specified in the “site sampling plan”
    required under subsection (a)(3)(B)(iii) of this Section, must be
    prepared and recorded to document the waste quantity
    represented by the samples and, as applicable, the operating
    conditions for the source or process generating the hazardous
    waste represented by the samples.
    C)
    Analysis. Each collected sample must be prepared and analyzed in
    accordance with one or more of the methods listed in subsections
    (a)(3)(C)(i) through (a)(3)(C)(ix) of this Section, including the
    appropriate quality assurance and quality control (QA/QC) checks and
    use of target compounds for calibration. If Method 25D in 40 CFR 60,

    103
    appendix A, incorporated by reference in 35 Ill. Adm. Code 720.111,
    is not used, then one or more methods should be chosen that are
    appropriate to ensure that the waste determination accounts for and
    reflects all organic compounds in the waste with Henry’s law constant
    values at least 0.1 mole-fraction-in-the-gas-phase/mole-fraction-in-the-
    liquid-phase (0.1 Y/X) (which can also be expressed as 1.8
    ×
    10
    -6
    atmospheres/gram-mole/m
    3
    ) at 25° C (77° F). Each of the analytical
    methods listed in subsections (a)(3)(C)(ii) through (a)(3)(C)(vii) of this
    Section has an associated list of approved chemical compounds for
    which USEPA considers the method appropriate for measurement. If
    an owner or operator uses USEPA Method 624, 625, 1624, or 1625
    in 40 CFR 136, appendix A, incorporated by reference in 35 Ill. Adm.
    Code 720.111, to analyze one or more compounds that are not on that
    method’s published list, the Alternative Test Procedure contained in 40
    CFR 136.4 and 136.5, incorporated by reference in 35 Ill. Adm. Code
    720.111, must be followed. If an owner or operator uses USEPA
    Method 8260 or 8270 in “Test Methods for Evaluating Solid Waste,
    Physical/Chemical Methods”, USEPA Publication SW-846,
    incorporated by reference in 35 Ill. Adm. Code 720.111, to analyze
    one or more compounds that are not on that method’s published list, the
    procedures in subsection (a)(3)(C)(viii) of this Section must be
    followed. At the owner’s or operator’s discretion, the concentration of
    each individual chemical constituent owner or operator may adjust test
    data measured in the waste by a method other than Method 25D may
    be corrected to the corresponding average VO concentration it value
    that would have had been obtained, had it the waste samples been
    measured analyzed using Method 25D. To adjust these data, by
    multiplying the measured concentration of each individual chemical
    constituent contained in the waste is multiplied by the constituent-
    specific adjustment factor (f
    m25D
    ), as specified in subsection (a)(4)(C) of
    this Section. If the owner or operator elects to adjust test data, the
    adjustment must be made to all individual chemical constituents with a
    Henry's law constant value greater than or equal to 0.1 Y/X at 25° C
    contained in the waste. Constituent-specific adjustment factors (f
    m25D
    )
    can be obtained by contacting the USEPA, Waste and Chemical
    Processes Group, Office of Air Quality Planning and Standards,
    Research Triangle Park, NC 27711.

    Method 8270 in “Test Methods for Evaluating Solid Waste,
    Physical/Chemical Methods”, USEPA Publication SW-846,
    incorporated by reference in 35 Ill. Adm. Code 720.111.
    Maintain a formal quality assurance program consistent with the
    requirements of Method 8270. The quality assurance program
    must include the elements set forth in subsection (a)(3)(F) of this
    Section.
    viii)
    Any other USEPA standard method that has been validated in
    accordance with “Alternative Validation Procedure for USEPA
    Waste and Wastewater Methods”, 40 CFR 63, appendix D,
    incorporated by reference in 35 Ill. Adm. Code 720.111. As
    an alternative, other USEPA standard methods may be
    validated by the procedure specified in subsection (a)(3)(C)(ix)
    of this Section.
    ix)
    Any other analysis method that has been validated in
    accordance with the procedures specified in Section 5.1 or
    Section 5.3, and the corresponding calculations in Section 6.1
    or Section 6.3, of Method 301 in 40 CFR 63, appendix A,
    incorporated by reference in 35 Ill. Adm. Code 720.111. The
    data are acceptable if they meet the criteria specified in Section

    105
    6.1.5 or Section 6.3.3 of Method 301. If correction is required
    under Section 6.3.3 of Method 301, the data are acceptable if
    the correction factor is within the range 0.7 to 1.30. Other
    Sections of Method 301 are not required.
    D)
    Calculations.
    i)
    The average VO concentration ( C ) on a mass-weighted basis
    must be calculated by using the results for all waste
    determinations conducted in accordance with subsections
    (a)(3)(B) and (a)(3)(C) of this Section and the following
    equation:
    C =
    1
    Q
    x
    n
    i = 1
    (Q x C )
    T
    i
    i
    Where:
    C =
    Average VO concentration of the hazardous waste at
    the point of waste origination on a mass-weighted basis,
    in ppmw.
    i =
    Individual waste determination “i” of the hazardous
    waste.
    n =
    Total number of waste determinations of the hazardous
    waste conducted for the averaging period (not to
    exceed one year).
    Q
    i
    =
    Mass quantity of the hazardous waste stream
    represented by C
    i
    , in kg/hr.
    Q
    T
    =
    Total mass quantity of the hazardous waste during the
    averaging period, in kg/hr.
    C
    i
    =
    Measured VO concentration of waste determination “i”,
    as determined in accordance with subsection (a)(3)(C)
    of this Section (i.e., the average of the four or more
    samples specified in subsection (a)(3)(B)(ii) of this
    Section), in ppmw.

    106
    ii)
    For the purpose of determining C
    i
    , for individual waste samples
    analyzed in accordance with subsection (a)(3)(C) of this
    Section, the owner or operator shall account for VO
    concentrations determined to be below the limit of detection of
    the analytical method by using the VO concentration determined
    according to subsection (a)(3)(G) of this Section.
    E)
    Provided that the test method is appropriate for the waste as required
    under subsection (a)(3)(C) of this Section, the Agency must determine
    compliance based on the test method used by the owner or operator as
    recorded pursuant to Section 725.990(f)(1).
    F)
    The quality assurance program elements required under subsections
    (a)(3)(C)(vi) and (a)(3)(C)(vii) of this Section are as follows:
    i)
    Documentation of site-specific procedures to minimize the loss
    of compounds due to volatilization, biodegradation, reaction, or
    sorption during the sample collection, storage, preparation,
    introduction, and analysis steps.
    ii)
    Measurement of the overall accuracy and precision of the
    specific procedures.
    BOARD NOTE: Subsections (a)(3)(F)(i) and (a)(3)(F)(ii) are derived
    from 40 CFR 265.984(a)(3)(iii)(F)(1), (a)(3)(iii)(F)(2),
    (a)(3)(iii)(G)(1), and (a)(3)(iii)(G)(2), which the Board has codified
    here to comport with Illinois Administrative Code format requirements.
    G)
    VO concentrations below the limit of detection must be considered to
    be as follows:
    i)
    If Method 25D in 40 CFR 60, appendix A, incorporated by
    reference in 35 Ill. Adm. Code 720.111, is used for the
    analysis, the VO concentration must be considered to be one-
    half the blank value determined in the method at Section 4.4 of
    Method 25D in 40 CFR 60, appendix A.
    ii)
    If any other analytical method is used, the VO concentration
    must be considered to be one-half the sum of the limits of
    detection established for each organic constituent in the waste
    that has a Henry’s law constant value at least 0.1 mole-fraction-
    in-the-gas-phase/mole-fraction-in-the-liquid-phase (0.1 Y/X)
    (which can also be expressed as 1.8 x 10
    -6
    atmospheres/gram-

    107
    mole/m
    3
    ) at 25° C.
    BOARD NOTE: Subsections (a)(3)(G)(i) and (a)(3)(G)(ii) are derived
    from 40 CFR 265.984(a)(3)(iv)(A)(1) and (a)(3)(iv)(A)(2), which the
    Board has codified here to comport with Illinois Administrative Code
    format requirements.
    4)
    Use of owner or operator knowledge to determine average VO concentration
    of a hazardous waste at the point of waste origination.
    A)
    Documentation must be prepared that presents the information used as
    the basis for the owner’s or operator’s knowledge of the hazardous
    waste stream’s average VO concentration. Examples of information
    that may be used as the basis for knowledge include the following:
    material balances for the source or process generating the hazardous
    waste stream; constituent-specific chemical test data for the hazardous
    waste stream from previous testing that are still applicable to the current
    waste stream; previous test data for other locations managing the same
    type of waste stream; or other knowledge based on information
    included in manifests, shipping papers, or waste certification notices.
    B)
    If test data are used as the basis for knowledge, then the owner or
    operator shall document the test method, sampling protocol, and the
    means by which sampling variability and analytical variability are
    accounted for in the determination of the average VO concentration.
    For example, an owner or operator may use organic concentration test
    data for the hazardous waste stream that are validated in accordance
    with Method 301 in 40 CFR 63, appendix A, incorporated by
    reference in 35 Ill. Adm. Code 720.111, as the basis for knowledge of
    the waste.
    C)
    An owner or operator using chemical constituent-specific concentration
    test data as the basis for knowledge of the hazardous waste may adjust
    the test data to the corresponding average VO concentration value
    which that would have been obtained had the waste samples been
    analyzed using Method 25D in 40 CFR 60, appendix A, incorporated
    by reference in 35 Ill. Adm. Code 720.111. To adjust these data, the
    measured concentration for each individual chemical constituent
    contained in the waste is multiplied by the appropriate constituent-
    specific adjustment factor (f
    m25D
    ).
    D)
    In the event that the Agency and the owner or operator disagree on a
    determination of the average VO concentration for a hazardous waste

    108
    stream using knowledge, then the results from a determination of
    average VO concentration using direct measurement, as specified in
    subsection (a)(3) of this Section, must be used to establish compliance
    with the applicable requirements of this Subpart. The Agency may
    perform or request that the owner or operator perform this
    determination using direct measurement. The owner or operator may
    choose one or more appropriate methods to analyze each collected
    sample in accordance with the requirements of subsection (a)(3)(C) of
    this Section.
    b)
    Waste determination procedures for treated hazardous waste.
    1)
    An owner or operator shall perform the applicable waste determination for each
    treated hazardous waste placed in a waste management unit exempted under
    the provisions of Section 725.983(c)(2)(A) through (c)(2)(F) from using air
    emission controls in accordance with the standards specified in Sections
    725.985 through 725.988, as applicable to the waste management unit.
    A) An owner or operator shall make an initial determination of the average
    VO concentration of the waste stream before the first time any portion
    of the material in the treated waste stream is placed in the waste
    management unit exempt under Section 725.983(c)(2), (c)(3), or (c)(4)
    from using air emission controls. Thereafter, an owner or operator shall
    update the information used for the waste determination at least once
    every 12 months following the date of the initial waste determination.
    B) An owner or operator shall perform a new waste determination
    whenever changes to the process generating or treating the waste
    stream are reasonably likely to cause the average VO concentration of
    the hazardous waste to increase to such a level that the applicable
    treatment conditions specified in Section 725.983 (c)(2), (c)(3), or
    (c)(4) are not achieved.
    2)
    The owner or operator shall designate and record the specific provision in
    Section 725.983(c)(2) under which the waste determination is being
    performed. The waste determination for the treated hazardous waste must be
    performed using the applicable procedures specified in subsections (b)(3)
    through (b)(9) of this Section.
    3)
    Procedure to determine the average VO concentration of a hazardous waste at
    the point of waste treatment.
    A)
    Identification. The owner or operator shall identify and record the point

    109
    of waste treatment for the hazardous waste.
    B)
    Sampling. Samples of the hazardous waste stream must be collected at
    the point of waste treatment in such a manner such that volatilization of
    organics contained in the waste and in the subsequent sample is
    minimized and an adequately representative sample is collected and
    maintained for analysis by the selected method.
    i)
    The averaging period to be used for determining the average
    VO concentration for the hazardous waste stream on a mass-
    weighted average basis must be designated and recorded. The
    averaging period can represent any time interval that the owner
    or operator determines is appropriate for the hazardous waste
    stream but must not exceed one year.
    ii)
    A sufficient number of samples, but no fewer than four samples,
    must be collected and analyzed for a hazardous waste
    determination. All of the samples for a given waste
    determination must be collected within a one-hour period. The
    average of the four or more sample results constitutes a waste
    determination for the hazardous waste stream. One or more
    waste determinations may be required to represent the
    complete range of waste compositions and quantities that occur
    during the entire averaging period due to normal variations in the
    operating conditions for the source or process generating or
    treating the hazardous waste stream. Examples of such normal
    variations are seasonal variations in waste quantity or
    fluctuations in ambient temperature.
    iii)
    All samples must be collected and handled in accordance with
    written procedures prepared by the owner or operator and
    documented in a site sampling plan. This plan must describe the
    procedure by which representative samples of the hazardous
    waste stream are collected such so that a minimum loss of
    organics occurs throughout the sample collection and handling
    process, and by which sample integrity is maintained. A copy
    of the written sampling plan must be maintained on-site in the
    facility operating records. An example of an acceptable
    sampling plan includes a plan incorporating sample collection
    and handling procedures in accordance with the requirements
    specified in “Test Methods for Evaluating Solid Waste,
    Physical/Chemical Methods,” USEPA Publication No. SW-
    846, incorporated by reference in 35 Ill. Adm. Code 720.111,

    110
    or in Method 25D in 40 CFR 60, appendix A, incorporated by
    reference in 35 Ill. Adm. Code 720.111.
    iv)
    Sufficient information, as specified in the “site sampling plan”
    required under subsection (a)(3)(B)(iii) of this Section, must be
    prepared and recorded to document the waste quantity
    represented by the samples and, as applicable, the operating
    conditions for the process treating the hazardous waste
    represented by the samples.
    C)
    Analysis. Each collected sample must be prepared and analyzed in
    accordance with one or more of the methods listed in subsections
    (b)(3)(C)(i) through (b)(3)(C)(ix) of this Section, including appropriate
    quality assurance and quality control (QA/QC) checks and use of target
    compounds for calibration. When the owner or operator is making a
    waste determination for a treated hazardous waste that is to be
    compared to an average VO concentration at the point of waste
    origination or the point of waste entry to the treatment system, to
    determine if the conditions of 35 Ill. Adm. Code 724.982(c)(2)(A)
    through (c)(2)(F) or Section 725.983(c)(2)(A) through (c)(2)(F) are
    met, then the waste samples shall must be prepared and analyzed using
    the same method or methods as were used in making the initial waste
    determinations at the point of waste origination or at the point of entry
    to the treatment system. If Method 25D in 40 CFR 60, appendix A is
    not used, then one or more methods should be chosen that are
    appropriate to ensure that the waste determination accounts for and
    reflects all organic compounds in the waste with Henry’s law constant
    values at least 0.1 mole-fraction-in-the-gas-phase/mole-fraction-in-the-
    liquid-phase (0.1 Y/X) [which can also be expressed as 1.8
    ×
    10
    -6
    atmospheres/gram-mole/m
    3
    ] at 25 degrees Celsius. Each of the
    analytical methods listed in subsections (b)(3)(C)(ii) through
    (b)(3)(C)(vii) of this Section has an associated list of approved chemical
    compounds, for which USEPA considers the method appropriate for
    measurement. If an owner or operator uses USEPA Method 624, 625,
    1624, or 1625 in 40 CFR 136, appendix A, incorporated by reference
    in 35 Ill. Adm. Code 720.111, to analyze one or more compounds that
    are not on that method’s published list, the Alternative Test Procedure
    contained in 40 CFR 136.4 and 136.5, incorporated by reference in 35
    Ill. Adm. Code 720.111, must be followed. If an owner or operator
    uses USEPA Method 8260 or 8270 in “Test Methods for Evaluating
    Solid Waste, Physical/Chemical Methods”, USEPA Publication SW-
    846, incorporated by reference in 35 Ill. Adm. Code 720.111, to
    analyze one or more compounds that are not on that method’s

    111
    published list, the procedures in subsection (b)(3)(C)(viii) of this Section
    must be followed. At the owner’s or operator’s discretion, the
    concentration of each individual chemical constituent owner or operator
    may adjust test data measured in the waste by a method other than
    Method 25D may be corrected to the corresponding average VO
    concentration it value that would have had been obtained, had it the
    waste samples been measured analyzed using Method 25D. To adjust
    these data, by multiplying the measured concentration of each individual
    chemical constituent contained in the waste is multiplied by the
    constituent-specific adjustment factor (f
    m25D
    ), as specified in subsection
    (a)(4)(C) of this Section. If the owner or operator elects to adjust test
    data, the adjustment must be made to all individual chemical constituents
    with a Henry's law constant value greater than or equal to 0.1 Y/X at
    25° C contained in the waste. Constituent-specific adjustment factors
    (f
    m25D
    ) can be obtained by contacting the USEPA, Waste and Chemical
    Processes Group, Office of Air Quality Planning and Standards,
    Research Triangle Park, NC 27711.

    Procedure to determine the maximum organic vapor pressure of a hazardous waste in a
    tank.
    1)
    An owner or operator shall determine the maximum organic vapor pressure for
    each hazardous waste placed in a tank using Tank Level 1 controls in
    accordance with standards specified in Section 725.985(c).
    2)
    An owner or operator shall use either direct measurement, as specified in
    subsection (c)(3) of this Section, or knowledge of the waste, as specified by
    subsection (c)(4) of this Section, to determine the maximum organic vapor
    pressure that is representative of the hazardous waste composition stored or
    treated in the tank.
    3)
    Direct measurement to determine the maximum organic vapor pressure of a
    hazardous waste.
    A)
    Sampling. A sufficient number of samples must be collected to be
    representative of the waste contained in the tank. All samples must be
    conducted and handled in accordance with written procedures
    prepared by the owner or operator and documented in a site sampling
    plan. This plan must describe the procedure by which representative
    samples of the hazardous waste are collected such so that a minimum
    loss of organics occurs throughout the sample collection and handling
    process and by which sample integrity is maintained. A copy of the
    written sampling plan must be maintained on-site in the facility operating
    records. An example of an acceptable sampling plan includes a plan
    incorporating sample collection and handling procedures in accordance
    with the requirements specified in “Test Methods for Evaluating Solid
    Waste, Physical/Chemical Methods”, USEPA Publication No. SW-
    846, incorporated by reference in 35 Ill. Adm. Code 720.111, or in

    35 Ill. Adm. Code 720.111.
    B)
    Analysis. Any appropriate one of the following methods may be used
    to analyze the samples and compute the maximum organic vapor

    121
    pressure of the hazardous waste:
    i)
    Method 25E in 40 CFR 60, Appendix A, incorporated by
    reference in 35 Ill. Adm. Code 720.111;
    ii)
    Methods described in American Petroleum Institute Publication
    2517, incorporated by reference in 35 Ill. Adm. Code
    720.111;
    iii)
    Methods obtained from standard reference texts;
    iv)
    ASTM Method D 2879-92, incorporated by reference in 35
    Ill. Adm. Code 720.111; or
    v)
    Any other method approved by the Agency.
    4)
    Use of knowledge to determine the maximum organic vapor pressure of the
    hazardous waste. Documentation must be prepared and recorded that presents
    the information used as the basis for the owner’s or operator’s knowledge that
    the maximum organic vapor pressure of the hazardous waste is less than the
    maximum vapor pressure limit listed in Section 725.985(b)(1)(A) for the
    applicable tank design capacity category. An example of information that may
    be used is documentation that the hazardous waste is generated by a process
    for which at other locations it previously has been determined by direct
    measurement that the waste maximum organic vapor pressure is less than the
    maximum vapor pressure limit for the appropriate tank design capacity
    category.
    d)
    Procedure for determining no detectable organic emissions for the purpose of complying
    with this Subpart:
    1)
    The test must be conducted in accordance with the procedures specified in
    Method 21 of 40 CFR 60, appendix A, incorporated by reference in 35 Ill.
    Adm. Code 720.111. Each potential leak interface (i.e., a location where
    organic vapor leakage could occur) on the cover and associated closure
    devices must be checked. Potential leak interfaces that are associated with
    covers and closure devices include, but are not limited to any of the following:
    the interface of the cover and its foundation mounting, the periphery of any
    opening on the cover and its associated closure device, and the sealing seat
    interface on a spring-loaded pressure relief valve.
    2)
    The test must be performed when the unit contains a hazardous waste having an
    organic concentration representative of the range of concentrations for the

    122
    hazardous waste expected to be managed in the unit. During the test, the cover
    and closure devices must be secured in the closed position.
    3)
    The detection instrument must meet the performance criteria of Method 21 of
    40 CFR 60, appendix A, incorporated by reference in 35 Ill. Adm. Code
    720.111, except the instrument response factor criteria in Section 3.1.2(a) of
    Method 21 must be for the average composition of the organic constituents in
    the hazardous waste placed in the waste management unit, not for each
    individual organic constituent.
    4)
    The detection instrument must be calibrated before use on each day of its use
    by the procedures specified in Method 21 of 40 CFR 60, appendix A,
    incorporated by reference in 35 Ill. Adm. Code 720.111.
    5)
    Calibration gases must be as follows:
    A)
    Zero air (less than 10 ppmv hydrocarbon in air), and
    B)
    A mixture of methane or n-hexane in air at a concentration of
    approximately, but less than, 10,000 ppmv methane or n-hexane.
    6)
    The background level must be determined according to the procedures in
    Method 21 of 40 CFR 60, appendix A, incorporated by reference in 35 Ill.
    Adm. Code 720.111.
    7)
    Each potential leak interface must be checked by traversing the instrument
    probe around the potential leak interface as close to the interface as possible, as
    described in Method 21 of 40 CFR 60, appendix A, incorporated by reference
    in 35 Ill. Adm. Code 720.111. In the case when the configuration of the cover
    or closure device prevents a complete traverse of the interface, all accessible
    portions of the interface must be sampled. In the case when the configuration of
    the closure device prevents any sampling at the interface and the device is
    equipped with an enclosed extension or horn (e.g., some pressure relief
    devices), the instrument probe inlet must be placed at approximately the center
    of the exhaust area to the atmosphere.
    8)
    The arithmetic difference between the maximum organic concentration indicated
    by the instrument and the background level must be compared with the value of
    500 ppmv except when monitoring a seal around a rotating shaft that passes
    through a cover opening, in which case the comparison must be as specified in
    subsection (d)(9) of this Section. If the difference is less than 500 ppmv, then
    the potential leak interface is determined to operate with no detectable organic
    emissions.

    123
    9)
    For the seals around a rotating shaft that passes through a cover opening, the
    arithmetic difference between the maximum organic concentration indicated by
    the instrument and the background level must be compared with the value of
    10,000 ppmw. If the difference is less than 10,000 ppmw, then the potential
    leak interface is determined to operate with no detectable organic emissions.

    Section:
    1)
    The owner or operator shall determine the maximum organic vapor pressure for
    a hazardous waste to be managed in the tank using Tank Level 1 controls
    before the first time the hazardous waste is placed in the tank. The maximum
    organic vapor pressure must be determined using the procedures specified in
    Section 725.984(c). Thereafter, the owner or operator shall perform a new
    determination whenever changes to the hazardous waste managed in the tank
    could potentially cause the maximum organic vapor pressure to increase to a
    level that is equal to or greater than the maximum organic vapor pressure limit
    for the tank design capacity category specified in subsection (b)(1)(A) of this
    Section, as applicable to the tank.
    2)
    The tank must be equipped with a fixed roof designed to meet the following
    specifications:
    A)
    The fixed roof and its closure devices must be designed to form a
    continuous barrier over the entire surface area of the hazardous waste in
    the tank. The fixed roof may be a separate cover installed on the tank
    (e.g., a removable cover mounted on an open-top tank) or may be an
    integral part of the tank structural design (e.g., a horizontal cylindrical
    tank equipped with a hatch).
    B)
    The fixed roof must be installed in such a manner such that there are no

    125
    visible cracks, holes, gaps, or other open spaces between roof section
    joints or between the interface of the roof edge and the tank wall.
    C)
    Either of the following must be true of each opening in the fixed roof and
    of any manifold system associated with the fixed roof must be either:
    i)
    The opening or manifold system is equipped with a closure
    device designed to operate such so that when the closure
    device is secured in the closed position there are no visible
    cracks, holes, gaps, or other open spaces in the closure device
    or between the perimeter of the opening and the closure device;
    or
    ii)
    The opening or manifold system is connected by a closed-vent
    system that is vented to a control device. The control device
    must remove or destroy organics in the vent stream, and it must
    be operating whenever hazardous waste is managed in the tank,
    except as provided for in subsection (c)(2)(E).
    D)
    The fixed roof and its closure devices must be made of suitable
    materials that will minimize exposure of the hazardous waste to the
    atmosphere, to the extent practical, and which will maintain the integrity
    of the fixed roof and closure devices throughout their intended service
    life. Factors to be considered when selecting the materials for and
    designing the fixed roof and closure devices must include the following:
    organic vapor permeability; the effects of any contact with the
    hazardous waste or its vapors managed in the tank; the effects of
    outdoor exposure to wind, moisture, and sunlight; and the operating
    practices used for the tank on which the fixed roof is installed.
    E)
    The control device operated pursuant to subsection (c)(2)(C) of this
    Section needs not remove or destroy organics in the vent stream under
    the following conditions:
    i)
    During periods when it is necessary to provide access to the
    tank for performing the activities of subsection (c)(2)(E)(ii) of
    this Section, venting of the vapor headspace underneath the
    fixed roof to the control device is not required, opening of
    closure devices is allowed, and removal of the fixed roof is
    allowed. Following completion of the activity, the owner or
    operator shall promptly secure the closure device in the closed
    position or reinstall the cover, as applicable, and resume
    operation of the control device; and

    126
    ii)
    During periods of routine inspection, maintenance, or other
    activities needed for normal operations, and for the removal of
    accumulated sludge or other residues from the bottom of the
    tank.
    BOARD NOTE: Subsections (c)(2)(E)(i) and (c)(2)(E)(ii) are derived
    from 40 CFR 265.985(c)(2)(iii)(B)(1) and (c)(2)(iii)(B)(2), which the
    Board has codified here to comport with Illinois Administrative Code
    format requirements.
    3)
    Whenever a hazardous waste is in the tank, the fixed roof must be installed with
    each closure device secured in the closed position, except as follows:
    A)
    Opening of closure devices or removal of the fixed roof is allowed at
    the following times:
    i)
    To provide access to the tank for performing routine inspection,
    maintenance, or other activities needed for normal operations.
    Examples of such activities include those times when a worker
    needs to open a port to sample the liquid in the tank, or when a
    worker needs to open a hatch to maintain or repair equipment.
    Following completion of the activity, the owner or operator shall
    promptly secure the closure device in the closed position or
    reinstall the cover, as applicable, to the tank.
    ii)
    To remove accumulated sludge or other residues from the
    bottom of tank.
    B)
    Opening of a spring-loaded pressure-vacuum relief valve, conservation
    vent, or similar type of pressure relief device which that vents to the
    atmosphere is allowed during normal operations for the purpose of
    maintaining the tank internal pressure in accordance with the tank design
    specifications. The device must be designed to operate with no
    detectable organic emissions when the device is secured in the closed
    position. The settings at which the device opens must be established
    such so that the device remains in the closed position whenever the tank
    internal pressure is within the internal pressure operating range
    determined by the owner or operator based on the tank manufacturer
    recommendations; applicable regulations; fire protection and prevention
    codes; standard engineering codes and practices; or other requirements
    for the safe handling of flammable, ignitable, explosive, reactive, or
    hazardous materials. Examples of normal operating conditions that may

    127
    require these devices to open are during those times when the tank
    internal pressure exceeds the internal pressure operating range for the
    tank as a result of loading operations or diurnal ambient temperature
    fluctuations.
    C)
    Opening of a safety device, as defined in Section 725.981, is allowed at
    any time conditions require doing so to avoid an unsafe condition.

    emissions. Defects include, but are not limited to, visible cracks, holes,
    or gaps in the roof sections or between the roof and the tank wall;
    broken, cracked, or otherwise damaged seals or gaskets on closure
    devices; and broken or missing hatches, access covers, caps, or other
    closure devices.
    B)
    The owner or operator shall perform an initial inspection of the fixed
    roof and its closure devices on or before the date that the tank becomes
    subject to this Section. Thereafter, the owner or operator shall perform
    the inspections at least once every year, except under the special
    conditions provided for in subsection (l) of this Section.
    C)
    In the event that a defect is detected, the owner or operator shall repair
    the defect in accordance with the requirements of subsection (k) of this
    Section.
    D)
    The owner or operator shall maintain a record of the inspection in
    accordance with the requirements specified in Section 725.990(b).

    ii)
    Prior to each visual inspection of an external floating roof in a
    tank that has been emptied and degassed, written notification
    must be prepared and sent by the owner or operator so that it is
    received by the Agency at least 30 calendar days before refilling
    the tank except when an inspection is not planned, as provided
    for in subsection (f)(3)(C)(iii) of this Section.
    iii)
    When a visual inspection is not planned and the owner or
    operator could not have known about the inspection 30
    calendar days before refilling the tank, the owner or operator
    shall notify the Agency as soon as possible, but no later than
    seven calendar days before refilling of the tank. This notification
    may be made by telephone and immediately followed by a
    written explanation for why the inspection is unplanned.
    Alternatively, written notification, including the explanation for
    the unplanned inspection, may be sent so that it is received by
    the Regional Administrator at least seven calendar days before
    refilling the tank.
    D)
    Procedure for determining gaps in the primary seal and in the secondary
    seal for the purposes of subsection (f)(3)(A)(iv) of this Section:
    i)
    The seal gap measurements must be performed at one or more
    floating roof levels when the roof is floating off the roof

    136
    supports.
    ii)
    Seal gaps, if any, must be measured around the entire perimeter
    of the floating roof in each place where a 0.32-cm (¼-inch)
    diameter uniform probe passes freely (without forcing or binding
    against the seal) between the seal and the wall of the tank and
    measure the circumferential distance of each such location.
    iii)
    For a seal gap measured under this subsection (f)(3), the gap
    surface area must be determined by using probes of various
    widths to measure accurately the actual distance from the tank
    wall to the seal and multiplying each such width by its respective
    circumferential distance.
    iv)
    The total gap area must be calculated by adding the gap surface
    areas determined for each identified gap location for the primary
    seal and the secondary seal individually, and then dividing the
    sum for each seal type by the nominal diameter of the tank.
    These total gap areas for the primary seal and secondary seal
    are then compared to the respective standards for the seal type,
    as specified in subsection (f)(1)(B) of this Section.
    BOARD NOTE: Subsections (f)(3)(D)(i) through (f)(3)(D)(iv) are
    derived from 40 CFR 265.1085(f)(3)(i)(D)(1) through (f)(3)(i)(D)(4),
    which the Board has codified here to comport with Illinois
    Administrative Code format requirements.
    4)
    Safety devices, as defined in Section 725.981, may be installed and operated as
    necessary on any tank complying with the requirements of this subsection (f).
    g)
    The owner or operator that controls air pollutant emissions from a tank by venting the
    tank to a control device shall meet the requirements specified in subsections (g)(1)
    through (g)(3) of this Section.
    1)
    The tank must be covered by a fixed roof and vented directly through a closed-
    vent system to a control device in accordance with the following requirements:
    A)
    The fixed roof and its closure devices must be designed to form a
    continuous barrier over the entire surface area of the liquid in the tank.
    B)
    Each opening in the fixed roof not vented to the control device must be
    equipped with a closure device. If the pressure in the vapor headspace
    underneath the fixed roof is less than atmospheric pressure when the

    137
    control device is operating, the closure devices must be designed to
    operate such so that when the closure device is secured in the closed
    position there are no visible cracks, holes, gaps, or other open spaces in
    the closure device or between the perimeter of the cover opening and
    the closure device. If the pressure in the vapor headspace underneath
    the fixed roof is equal to or greater than atmospheric pressure when the
    control device is operating, the closure device must be designed to
    operate with no detectable organic emissions.
    C)
    The fixed roof and its closure devices must be made of suitable
    materials that will minimize exposure of the hazardous waste to the
    atmosphere, to the extent practical, and will maintain the integrity of the
    fixed roof and closure devices throughout their intended service life.
    Factors to be considered when selecting the materials for and designing
    the fixed roof and closure devices must include the following: organic
    vapor permeability; the effects of any contact with the liquid and its
    vapor managed in the tank; the effects of outdoor exposure to wind,
    moisture, and sunlight; and the operating practices used for the tank on
    which the fixed roof is installed.
    D)

    operated in accordance with the requirements of Section 725.988.
    2)
    Whenever a hazardous waste is in the tank, the fixed roof must be installed with
    each closure device secured in the closed position and the vapor headspace
    underneath the fixed roof vented to the control device except as follows:
    A)
    Venting to the control device is not required, and opening of closure
    devices or removal of the fixed roof is allowed at the following times:
    i)
    To provide access to the tank for performing routine inspection,
    maintenance, or other activities needed for normal operations.
    Examples of such activities include those times when a worker
    needs to open a port to sample liquid in the tank, or when a
    worker needs to open a hatch to maintain or repair equipment.
    Following completion of the activity, the owner or operator shall
    promptly secure the closure device in the closed position or
    reinstall the cover, as applicable, to the tank.
    ii)
    To remove accumulated sludge or other residues from the
    bottom of a tank.
    B)

    2)
    Repair of a defect may be delayed beyond 45 calendar days if the owner or
    operator determines that repair of the defect requires emptying or temporary
    removal from service of the tank and no alternative tank capacity is available at
    the site to accept the hazardous waste normally managed in the tank. In this
    case, the owner or operator shall repair the defect the next time the process or
    unit that is generating the hazardous waste managed in the tank stops operation.
    Repair of the defect must be completed before the process or unit resumes
    operation.
    l)
    Following the initial inspection and monitoring of the cover as required by the applicable
    provisions of this Subpart, subsequent inspection and monitoring may be performed at

    141
    intervals longer than one year under the following special conditions:
    1)
    Where inspecting or monitoring the cover would expose a worker to
    dangerous, hazardous, or other unsafe conditions, then the owner or operator
    may designate a cover as an “unsafe to inspect and monitor cover” and comply
    with all of the following requirements:
    A)
    Prepare a written explanation for the cover stating the reasons why the
    cover is unsafe to visually inspect or to monitor, if required.

    (120 gal)
    that is in light material service, the owner or operator shall control air
    pollutant emissions from the container in accordance with the Container
    Level 2 standards specified in subsection (d) of this Section.
    2)
    When a container having a design capacity greater than 0.1 m
    3
    (26 gal) is used
    for treatment of a hazardous waste by a waste stabilization process, the owner
    or operator shall control air pollutant emissions from the container in
    accordance with the Container Level 3 standards specified in subsection (e) of
    this Section at those times during the waste stabilization process when the
    hazardous waste in the container is exposed to the atmosphere.
    c)
    Container Level 1 standards.
    1)
    A container using Container Level 1 controls is one of the following:
    A)
    A container that meets the applicable U.S. Department of
    Transportation (USDOT) regulations on packaging hazardous materials
    for transportation, as specified in subsection (f) of this Section.
    B)
    A container equipped with a cover and closure devices that form a
    continuous barrier over the container openings so that when the cover
    and closure devices are secured in the closed position there are no
    visible holes, gaps, or other open spaces into the interior of the
    container. The cover may be a separate cover installed on the container
    (e.g., a lid on a drum or a suitably secured tarp on a roll-off box) or
    may be an integral part of the container structural design (e.g., a
    “portable tank” or bulk cargo container equipped with a screw-type
    cap).
    C)
    An open-top container in which an organic-vapor suppressing barrier is
    placed on or over the hazardous waste in the container such so that no
    hazardous waste is exposed to the atmosphere. One example of such a
    barrier is application of a suitable organic-vapor suppressing foam.
    2)
    A container used to meet the requirements of subsection (c)(1)(B) or (c)(1)(C)
    of this Section must be equipped with covers and closure devices, as applicable
    to the container, that are composed of suitable materials to minimize exposure
    of the hazardous waste to the atmosphere and to maintain the equipment

    143
    integrity for as long as it is in service. Factors to be considered in selecting the
    materials of construction and designing the cover and closure devices must
    include the following: the organic vapor permeability, the effects of contact with
    the hazardous waste or its vapor managed in the container; the effects of
    outdoor exposure of the closure device or cover material to wind, moisture, and
    sunlight; and the operating practices for which the container is intended to be
    used.
    3)
    Whenever a hazardous waste is in a container using Container Level 1 controls,
    the owner or operator shall install all covers and closure devices for the
    container, as applicable to the container, and secure and maintain each closure
    device in the closed position except as follows:
    A)
    Opening of a closure device or cover is allowed for the purpose of
    adding hazardous waste or other material to the container as follows:
    i)
    In the case when the container is filled to the intended final level
    in one continuous operation, the owner or operator shall
    promptly secure the closure devices in the closed position and
    install the covers, as applicable to the container, upon
    conclusion of the filling operation.
    ii)
    In the case when discrete quantities or batches of material
    intermittently are added to the container over a period of time,
    the owner or operator shall promptly secure the closure devices
    in the closed position and install covers, as applicable to the
    container, upon either the container being filled to the intended
    final level; the completion of a batch loading after which no
    additional material will be added to the container within 15
    minutes; the person performing the loading operation leaving the
    immediate vicinity of the container; or the shutdown of the
    process generating the material being added to the container,
    whichever condition occurs first.
    B)
    Opening of a closure device or cover is allowed for the purpose of
    removing hazardous waste from the container as follows:
    i)
    For the purpose of meeting the requirements of this Section, an
    empty container, as defined in 35 Ill. Adm. Code 721.107(b),
    may be open to the atmosphere at any time (i.e., covers and
    closure devices are not required to be secured in the closed
    position on an empty container).

    144
    ii)
    In the case when discrete quantities or batches of material are
    removed from the container but the container does not meet the
    conditions to be an empty container, as defined in 35 Ill. Adm.
    Code 721.107(b), the owner or operator shall promptly secure
    the closure devices in the closed position and install covers, as
    applicable to the container, upon the completion of a batch
    removal after which no additional material will be removed from
    the container within 15 minutes or the person performing the
    unloading operation leaves the immediate vicinity of the
    container, whichever condition occurs first.
    C)
    Opening of a closure device or cover is allowed when access inside the
    container is needed to perform routine activities other than transfer of
    hazardous waste. Examples of such activities include those times when
    a worker needs to open a port to measure the depth of or sample the
    material in the container, or when a worker needs to open a manhole
    hatch to access equipment inside the container. Following completion
    of the activity, the owner or operator shall promptly secure the closure
    device in the closed position or reinstall the cover, as applicable to the
    container.
    D)
    Opening of a spring-loaded, pressure-vacuum relief valve, conservation
    vent, or similar type of pressure relief device which that vents to the
    atmosphere is allowed during normal operations for the purpose of
    maintaining the container internal pressure in accordance with the design
    specifications of the container. The device must be designed to operate
    with no detectable organic emissions when the device is secured in the
    closed position. The settings at which the device opens must be
    established such so that the device remains in the closed position
    whenever the internal pressure of the container is within the internal
    pressure operating range determined by the owner or operator based
    on container manufacturer recommendations, applicable regulations, fire
    protection and prevention codes, standard engineering codes and
    practices, or other requirements for the safe handling of flammable,
    ignitable, explosive, reactive, or hazardous materials. Examples of
    normal operating conditions that may require these devices to open are
    during those times when the internal pressure of the container exceeds
    the internal pressure operating range for the container as a result of
    loading operations or diurnal ambient temperature fluctuations.
    E)
    Opening of a safety device, as defined in Section 725.981, is allowed at
    any time conditions require doing so to avoid an unsafe condition.

    145
    4)
    The owner or operator of containers using Container Level 1 controls must
    inspect the containers and their covers and closure devices as follows:
    A)
    In the case when a hazardous waste already is in the container at the
    time the owner or operator first accepts possession of the container at
    the facility and the container is not emptied within 24 hours after the
    container is accepted at the facility (i.e., it does not meet the conditions
    for an empty container as specified in 35 Ill. Adm. Code 721.107(b)),
    the owner or operator shall visually inspect the container and its cover
    and closure devices to check for visible cracks, holes, gaps, or other
    open spaces into the interior of the container when the cover and
    closure devices are secured in the closed position. The container visual
    inspection must be conducted on or before the date on which the
    container is accepted at the facility (i.e., the date when the container
    becomes subject to the Subpart CC container standards). For the
    purposes of this requirement, the date of acceptance is the date of
    signature that the facility owner or operator enters on Item 20 of the
    Uniform Hazardous Waste Manifest incorporated by reference in 35 Ill.
    Adm. Code 722.Appendix A (USEPA Forms 8700-22 and 8700-
    22A), as required under Section 725.171. If a defect is detected, the
    owner or operator shall repair the defect in accordance with the
    requirements of subsection (c)(4)(C) of this Section.
    B)
    In the case when a container used for managing hazardous waste
    remains at the facility for a period of one year or more, the owner or
    operator shall visually inspect the container and its cover and closure
    devices initially and thereafter, at least once every 12 months, to check
    for visible cracks, holes, gaps, or other open spaces into the interior of
    the container when the cover and closure devices are secured in the
    closed position. If a defect is detected, the owner or operator shall
    repair the defect in accordance with the requirements of subsection
    (c)(4)(C) of this Section.
    C)
    When a defect is detected for the container, cover, or closure devices,
    the owner or operator shall make first efforts at repair of the defect no
    later than 24 hours after detection, and repair must be completed as
    soon as possible but no later than five calendar days after detection. If
    repair of a defect cannot be completed within five calendar days, then
    the hazardous waste must be removed from the container and the
    container must not be used to manage hazardous waste until the defect
    is repaired.
    5)
    The owner or operator shall maintain at the facility a copy of the procedure

    146
    used to determine that containers with capacity of 0.46 m
    3
    (120 gal) or greater,
    which do not meet applicable USDOT regulations as specified in subsection (f)
    of this Section, are not managing hazardous waste in light material service.
    d)
    Container Level 2 standards.
    1)
    A container using Container Level 2 controls is one of the following:
    A)
    A container that meets the applicable U.S. Department of
    Transportation (USDOT) regulations on packaging hazardous materials
    for transportation as specified in subsection (f) of this Section.
    B)
    A container that operates with no detectable organic emissions, as
    defined in Section 725.981, and determined in accordance with the
    procedure specified in subsection (g) of this Section.
    C)
    A container that has been demonstrated within the preceding 12 months
    to be vapor-tight by using 40 CFR 60, appendix A, Method 27,
    incorporated by reference in 35 Ill. Adm. Code 720.111, in
    accordance with the procedure specified in subsection (h) of this
    Section.
    2)
    Transfer of hazardous waste in or out of a container using Container Level 2
    controls must be conducted in such a manner as to minimize exposure of the
    hazardous waste to the atmosphere, to the extent practical, considering the
    physical properties of the hazardous waste and good engineering and safety
    practices for handling flammable, ignitable, explosive, reactive or other
    hazardous materials. Examples of container loading procedures that the
    USEPA considers to meet the requirements of this subsection (d)(2) include
    using any one of the following: a submerged-fill pipe or other submerged-fill
    method to load liquids into the container; a vapor-balancing system or a vapor-
    recovery system to collect and control the vapors displaced from the container
    during filling operations; or a fitted opening in the top of a container through
    which the hazardous waste is filled and subsequently purging the transfer line
    before removing it from the container opening.
    3)
    Whenever a hazardous waste is in a container using Container Level 2 controls,
    the owner or operator shall install all covers and closure devices for the
    container, and secure and maintain each closure device in the closed position,
    except as follows:
    A)
    Opening of a closure device or cover is allowed for the purpose of
    adding hazardous waste or other material to the container as follows:

    147
    i)
    In the case when the container is filled to the intended final level
    in one continuous operation, the owner or operator shall
    promptly secure the closure devices in the closed position and
    install the covers, as applicable to the container, upon
    conclusion of the filling operation.
    ii)
    In the case when discrete quantities or batches of material
    intermittently are added to the container over a period of time,
    the owner or operator shall promptly secure the closure devices
    in the closed position and install covers, as applicable to the
    container, upon either the container being filled to the intended
    final level; the completion of a batch loading after which no
    additional material will be added to the container within 15
    minutes; the person performing the loading operation leaving the
    immediate vicinity of the container; or the shutdown of the
    process generating the material being added to the container,
    whichever condition occurs first.
    B)
    Opening of a closure device or cover is allowed for the purpose of
    removing hazardous waste from the container as follows:
    i)
    For the purpose of meeting the requirements of this Section, an
    empty container as defined in 35 Ill. Adm. Code 721.107(b)
    may be open to the atmosphere at any time (i.e., covers and
    closure devices are not required to be secured in the closed
    position on an empty container).
    ii)
    In the case when discrete quantities or batches of material are
    removed from the container but the container does not meet the
    conditions to be an empty container as defined in 35 Ill. Adm.
    Code 721.107(b), the owner or operator shall promptly secure
    the closure devices in the closed position and install covers, as
    applicable to the container, upon the completion of a batch
    removal after which no additional material will be removed from
    the container within 15 minutes or the person performing the

    container, whichever condition occurs first.
    C)
    Opening of a closure device or cover is allowed when access inside the
    container is needed to perform routine activities other than transfer of
    hazardous waste. Examples of such activities include those times when
    a worker needs to open a port to measure the depth of or sample the

    148
    material in the container, or when a worker needs to open a manhole
    hatch to access equipment inside the container. Following completion
    of the activity, the owner or operator shall promptly secure the closure
    device in the closed position or reinstall the cover, as applicable to the
    container.
    D)
    Opening of a spring-loaded, pressure-vacuum relief valve, conservation
    vent, or similar type of pressure relief device which that vents to the
    atmosphere is allowed during normal operations for the purpose of
    maintaining the internal pressure of the container in accordance with the
    container design specifications. The device must be designed to
    operate with no detectable organic emission when the device is secured
    in the closed position. The settings at which the device opens must be
    established such so that the device remains in the closed position
    whenever the internal pressure of the container is within the internal
    pressure operating range determined by the owner or operator based
    on container manufacturer recommendations, applicable regulations, fire
    protection and prevention codes, standard engineering codes and
    practices, or other requirements for the safe handling of flammable,
    ignitable, explosive, reactive, or hazardous materials. Examples of
    normal operating conditions that may require these devices to open are
    during those times when the internal pressure of the container exceeds
    the internal pressure operating range for the container as a result of
    loading operations or diurnal ambient temperature fluctuations.
    E)
    Opening of a safety device, as defined in Section 725.981, is allowed at
    any time conditions require doing so to avoid an unsafe condition.
    4)
    The owner or operator of containers using Container Level 2 controls shall
    inspect the containers and their covers and closure devices as follows:
    A)
    In the case when a hazardous waste already is in the container at the
    time the owner or operator first accepts possession of the container at
    the facility and the container is not emptied within 24 hours after the
    container is accepted at the facility (i.e., it does not meet the conditions
    for an empty container as specified in 35 Ill. Adm. Code 721.107(b)),
    the owner or operator shall visually inspect the container and its cover
    and closure devices to check for visible cracks, holes, gaps, or other
    open spaces into the interior of the container when the cover and
    closure devices are secured in the closed position. The container visual
    inspection must be conducted on or before the date on which the
    container is accepted at the facility (i.e., the date when the container
    becomes subject to the Subpart CC container standards). For the

    149
    purposes of this requirement, the date of acceptance is the date of
    signature that the facility owner or operator enters on Item 20 of the
    Uniform Hazardous Waste Manifest incorporated by reference in 35 Ill.
    Adm. Code 722.Appendix A (USEPA Forms 8700-22 and 8700-
    22A), as required under Section 725.171. If a defect is detected, the
    owner or operator shall repair the defect in accordance with the
    requirements of subsection (d)(4)(C) of this Section.
    B)
    In the case when a container used for managing hazardous waste
    remains at the facility for a period of one year or more, the owner or
    operator shall visually inspect the container and its cover and closure
    devices initially and thereafter, at least once every 12 months, to check
    for visible cracks, holes, gaps, or other open spaces into the interior of
    the container when the cover and closure devices are secured in the
    closed position. If a defect is detected, the owner or operator shall
    repair the defect in accordance with the requirements of subsection
    (d)(4)(C) of this Section.
    C)
    When a defect is detected for the container, cover, or closure devices,
    the owner or operator shall make first efforts at repair of the defect no
    later than 24 hours after detection, and repair must be completed as
    soon as possible but no later than five calendar days after detection. If
    repair of a defect cannot be completed within five calendar days, then
    the hazardous waste must be removed from the container and the
    container must not be used to manage hazardous waste until the defect
    is repaired.
    e)
    Container Level 3 standards.
    1)
    A container using Container Level 3 controls is one of the following:
    A)
    A container that is vented directly through a closed-vent system to a
    control device in accordance with the requirements of subsection
    (e)(2)(B) of this Section.
    B)
    A container that is vented inside an enclosure which is exhausted
    through a closed-vent system to a control device in accordance with the
    requirements of subsections (e)(2)(A) and (e)(2)(B) of this Section.
    2)
    The owner or operator shall meet the following requirements, as applicable to
    the type of air emission control equipment selected by the owner or operator:
    A)
    The container enclosure must be designed and operated in accordance

    150
    with the criteria for a permanent total enclosure as specified in
    “Procedure T--Criteria for and Verification of a Permanent or
    Temporary Total Enclosure” under 40 CFR 52.741, appendix B,
    incorporated by reference in 35 Ill. Adm. Code 720.111. The
    enclosure may have permanent or temporary openings to allow worker
    access; passage of containers through the enclosure by conveyor or
    other mechanical means; entry of permanent mechanical or electrical
    equipment; or direct airflow into the enclosure. The owner or operator
    shall perform the verification procedure for the enclosure as specified in
    Section 5.0 to “Procedure T--Criteria for and Verification of a
    Permanent or Temporary Total Enclosure” initially when the enclosure is
    first installed and, thereafter, annually.
    B)
    The closed-vent system and control device must be designed and
    operated in accordance with the requirements of Section 725.988.
    3)
    Safety devices, as defined in Section 725.981, may be installed and operated as
    necessary on any container, enclosure, closed-vent system, or control device
    used to comply with the requirements of subsection (e)(1) of this Section.
    4)
    Owners and operators using Container Level 3 controls in accordance with the
    provisions of this Subpart shall inspect and monitor the closed-vent systems and
    control devices, as specified in Section 725.988.
    5)
    Owners and operators that use Container Level 3 controls in accordance with
    the provisions of this Subpart shall prepare and maintain the records specified in
    Section 725.990(d).
    6) The transfer of hazardous waste into or out of a container using Container Level
    3 controls must be conducted in such a manner as to minimize exposure of the
    hazardous waste to the atmosphere, to the extent practical considering the
    physical properties of the hazardous waste and good engineering and safety
    practices for handling flammable, ignitable, explosive, reactive, or other
    hazardous materials. Examples of container loading procedures that USEPA
    considers to meet the requirements of this subsection (e)(6) include using any
    one of the following: the use of a submerged-fill pipe or other submerged-fill
    method to load liquids into the container; the use of a vapor-balancing system or
    a vapor-recovery system to collect and control the vapors displaced from the
    container during filling operations; or the use of a fitted opening in the top of a
    container through which the hazardous waste is filled and subsequently purging
    the transfer line before removing it from the container opening.
    f)
    For the purpose of compliance with subsection (c)(1)(A) or (d)(1)(A) of this Section,

    151
    containers must be used that meet the applicable U.S. Department of Transportation
    (USDOT) regulations on packaging hazardous materials for transportation as follows:
    1)
    The container meets the applicable requirements specified in 49 CFR 178,
    “Specifications for Packaging”, or 49 CFR 179, “Specifications for Tank
    Cars”, both incorporated by reference in 35 Ill. Adm. Code 720.111.
    2)
    Hazardous waste is managed in the container in accordance with the applicable
    requirements specified in 49 CFR 107, subpart B, “Exemptions”; 49 CFR 172,
    “Hazardous Materials Table, Special Provisions, Hazardous Materials
    Communications, Emergency Response Information, and Training
    Requirements”; 49 CFR 173, “Shippers--General Requirements for Shipments
    and Packages”; and 49 CFR 180, “Continuing Qualification and Maintenance
    of Packagings”, each incorporated by reference in 35 Ill. Adm. Code 720.111.
    3)
    For the purpose of complying with this Subpart, no exceptions to the 49 CFR
    178 or 179 regulations are allowed, except as provided for in subsection (f)(4)
    of this Section.
    4)
    For a lab pack that is managed in accordance with the requirements of 49 CFR
    178 for the purpose of complying with this Subpart, an owner or operator may
    comply with the exceptions for combination packagings specified in 49 CFR
    173.12(b), incorporated by reference in 35 Ill. Adm. Code 720.111.
    g)
    To determine compliance with the no detectable organic emissions requirements of
    subsection (d)(1)(B) of this Section, the procedure specified in Section 725.984(d)
    must be used.
    1)
    Each potential leak interface (i.e., a location where organic vapor leakage could
    occur) on the container, its cover, and associated closure devices, as applicable
    to the container, must be checked. Potential leak interfaces that are associated
    with containers include, but are not limited to: the interface of the cover rim and
    the container wall; the periphery of any opening on the container or container
    cover and its associated closure device; and the sealing seat interface on a
    spring-loaded pressure-relief valve.
    2)
    The test must be performed when the container is filled with a material having a
    volatile organic concentration representative of the range of volatile organic
    concentrations for the hazardous wastes expected to be managed in this type of
    container. During the test, the container cover and closure devices must be
    secured in the closed position.
    h)
    Procedure The procedure for determining a container to be vapor-tight using Method

    152
    27 of 40 CFR 60, appendix A for the purpose of complying with subsection (d)(1)(C)
    of this Section. is as follows:
    1)
    The test must be performed in accordance with Method 27 of 40 CFR 60,
    appendix A, incorporated by reference in 35 Ill. Adm. Code 720.111.
    2)
    A pressure measurement device must be used that has a precision of ±2.5 mm
    (0.10 inch) water and that is capable of measuring above the pressure at which
    the container is to be tested for vapor tightness.
    3)
    If the test results determined by Method 27 indicate that the container sustains a
    pressure change less than or equal to 750 Pascals (0.11 psig) within five
    minutes after it is pressurized to a minimum of 4,500 Pascals (0.65 psig), then
    the container is determined to be vapor-tight.
