(Identical-in-Substance Rulemaking - Air)

(January 1, 2007 through June 30, 2007)

Adopted Rule. Final Order.

OPINION AND ORDER OF THE BOARD (by G.T. Girard):

This rulemaking is designed to update the definition of “volatile organic material”

(VOM) in the Board’s air pollution regulations (35 Ill. Adm. Code 211.7150). The update is

needed to ensure that Illinois’ regulations reflect the United States Environmental Protection

Agency’s (USEPA) most recent exemption of chemical compounds from regulation as ozone

precursors.

Today the Board adopts amendments that add a single compound to the list of those

exempted from the definition of VOM. That compound is 1,1,1,2,2,3,4,5,5,5-decafluoro-3-

methoxy-4-trifluoromethyl-pentane, which is also known as HFE–7300 or L–14787. The Board

also clarifies the amendments adopted in Exemptions from the Definition of VOM, USEPA

Amendments (July 1, 2004 through December 31, 2004), R05-16 (May 19, 2005) at the request

of the Illinois Environmental Protection Agency (Agency) to satisfy USEPA concerns.

See

72

Fed. Reg. 74250 (Dec. 31, 2007).

Section 9.1(e) of the Environmental Protection Act (Act) (415 ILCS 5/9.1(e) (2006))

mandates this rulemaking. That statutory provision requires the Board to exclude from the

definition of VOM those compounds determined by USEPA to be exempt from regulation under

the state implementation plans for ozone “due to negligible photochemical reactivity.” 415 ILCS

5/9.1(e) (2006). In addition, Section 9.1(e) of the Act requires the Board to conduct this

rulemaking pursuant to the provisions of Section 7.2(b) of the Act (415 ILCS 5/7.2(b) (2006))

for adopting rules that are “identical in substance” to the federal requirements.

Section 9.1(e) also provides that Title VII of the Act and Section 5-35 of the

Administrative Procedure Act (APA) (5 ILCS 100/5-35 (2006)) do not apply to this type of

rulemaking. Accordingly, the Board did not adopt a “First Notice” proposal, or a “Second

Notice” proposal for review by the Joint Committee on Administrative Rules (JCAR). However,

as provided in Section 9.1(e) of the Act, the Board, before adopting final rule amendments, did

provide notice of this rulemaking proposal in the

Illinois Register

, held one public hearing on the

proposal as required by the federal Clean Air Act (33 U.S.C. § 7410(a) (2005)), and allowed for

public comment.

In this opinion, the Board first provides information on the hearing and public comment

period. Then the Board discusses the issues and amendments involved in this proceeding.

Finally, the Board summarizes the history of federal and Illinois actions dealing with VOM

exemptions. The Board’s amendments to the definition of VOM are set forth in the order

following this opinion.

PUBLIC COMMENTS AND PUBLIC HEARING

The Board adopted a proposal for public comment in this matter on October 18, 2007. A

Notice of Proposed Amendments appeared in the November 2, 2007 issue of the

Illinois

Register

, at 31 Ill. Reg. 14679. The Board accepted public comment on the proposed

amendments for 45 days after that publication, until December 17, 2007. The Board received the

following two comments on the proposed amendments:

PC 1 Several e-mails and responses exchanged between Shannon Bilbruck, of the

Agency, and Michael J. McCambridge, Board Hearing Officer, between

September 20, 2007 and October 10, 2007, including an attachment entitled,

“Issue Paper: Exclusion of tertiary-Butyl Acetate from the Definition of VOM at

35 Ill. Adm. Code 211.715.”

PC 2 Proposed Rule by USEPA, published in the

Federal Register

on December 31,

2007, at 72 Fed. Reg. 74250, proposing to disapprove the existing Illinois

definition of VOM at 35 Ill. Adm. Code 211.7150 or, alternatively, to approve the

definition if certain amendments are made by the Board.

As required by the federal Clean Air Act (33 U.S.C. § 7410(a) (2005)), the Board also

held a public hearing (Tr.) in this rulemaking before Board Hearing Officer Michael J.

McCambridge on December 5, 2007 in Chicago. John Kim, Agency, Division of Legal Counsel,

appeared on behalf of the Agency and testified at that hearing.

The appropriate segments of the following discussion outline the comments and

testimony received in this matter.

DESCRIPTION OF USEPA ACTIONS AND BOARD AMENDMENTS

The amendments adopted today respond to a single USEPA amendment to the federal

definition of “volatile organic compound” (VOC), which has the same meaning as VOM as used

in the Illinois regulations. The Board includes a correction to the existing definition of VOM at

the request of the Agency. The following discussion describes the amendments.

The Addition of a Newly Exempted Compound

On January 18, 2007 (at 72 Fed. Reg. 2193), USEPA added a single compound to the list

of chemical species that are exempt from the federal definition of VOC and, accordingly, are

exempt from regulation for control of ozone precursors. That compound is 1,1,1,2,2,3,4,5,5,5-

decafluoro-3-methoxy-4-trifluoromethyl-pentane. It is also known as HFE–7300 or L–14787,

and has the empirical formula C

. With regard to the uses for this

---

compound, USEPA stated as follows in the preamble discussion of the amendment adding this

compound to the list of those exempted:

HFE–7300 has a variety of potential uses including as a heat transfer fluid and

substitute for ozone depleting substances and substances with high global

warming potentials, such as hydroflurocarbons, perfluorocarbons, and

perfluoropolyethers. HFE–7300 may be used in azeotropic mixtures for use in

coating deposition, cleaning, and lubricating applications. 72 Fed. Reg. 7293

(Jan. 18, 2007)

The Board today incorporates these federal amendments into the Illinois regulatory

definition of VOM at 35 Ill. Adm. Code 211.7150, with only minor differences from the federal

rule text. The table below provides the Board’s deviations from the federal text.

The Board did not receive any written public comments on the exemption of HFE-7300

from the definition of VOM. At the public hearing, the Agency represented that it had reviewed

the October 18, 2007 proposal and “has no concerns or objections as to the format and content of

the proposed rule.” Tr. at 5. The Board has adopted the proposed amendments without change

based on these Agency representations.

Correction of the Existing Text of the Definition of VOM and

PC 2 (USEPA Comments at 72 Fed. Reg. 74250 (Dec. 31. 2007))

One amendment corrects the text of the existing definition of VOM. This is to change

the text as previously amended based on earlier federal amendments. In Exemptions from the

Definition of VOM, USEPA Amendments (July 1, 2004 through December 31, 2004), R05-16

(May 19, 2005), the Board adopted amendments to the definition of VOM based on federal

amendments of November 29, 2004 (69 Fed. Reg. 69298). USEPA excluded an additional

compound from the VOC definition, for purposes of emissions limitations and VOC content

requirements, but retained the compound as VOC for purposes of recordkeeping, emissions

reporting, photochemical dispersion modeling, and inventory requirements.

When incorporating the November 29, 2004 federal amendments in docket R05-16, the

Board deviated from the text of the federal amendments. The Board added the exempted

compound,

tert

-butyl acetate, to the list of exempted compounds in Section 211.7150(a), in

---

4

addition to the federally derived text in Section 211.7150(e). USEPA, however, listed

tert

-butyl

acetate in 40 C.F.R. 51.100(s)(5) without also adding it to the listing of exempted compounds in

corresponding 40 C.F.R. 51.100(s)(1).

As an attachment to what the Board has designated Public Comment 1 (PC 1), the

Agency filed a document entitled, “Issue Paper: Exclusion of tertiary-Butyl Acetate from the

Definition of VOM at 35 Ill. Adm. Code 211.715” (“Issue Paper”). (See the discussion of public

comments at page 6 of this opinion and order.) The Issue Paper states that USEPA has not

approved the Illinois exemption of

tert

-butyl acetate from the definition of VOM because the

compound’s appearance in subsection (a) of the Illinois definition could lead to confusion that

the compound is totally exempt. The exemption in subsection (e), which closely follows the

corresponding USEPA exemption of

tert

-butyl acetate, is clearly limited in the same way as is

the federal exemption.

There are two possible ways to amend the Illinois definition of VOM that will dispel any

possible confusion as to the scope of the exemption of

tert

-butyl acetate from the definition.

Option A is to delete the appearance of “

tert

-butyl acetate” from the list of exempt compounds in

subsection (a). This approach would more closely follow the text of corresponding 40 C.F.R.

51.100(s)(1), in which

tert

-butyl acetate does not appear.

The disadvantage of pursuing Option A could lead to other confusion. It could cause

confusion as to the applicability of subsections (b) through (d) to

tert

-butyl acetate. Subsection

(b) sets forth monitoring requirements for VOM emissions. Subsection (c) allows the Agency to

require monitoring for exempted compounds to prove their quantity in emissions. Subsection (d)

states the fact that USEPA is not bound by a State determination as to monitoring methods for

exempted compounds beyond those methods cited in subsection (b). Each of these three

provisions relate to determining emissions of compounds that have “negligible photochemical

reactivity” or “negligibly-reactive compounds.”

Subsection (a) lists compounds that are exempted from the definition of VOM because

they have “negligible photochemical reactivity.” Subsection (e) lists

tert

-butyl acetate as

partially exempt from the definition of VOM, but does not mention it as having negligible

photochemical reactivity or as a negligibly reactive compound.

See

35 Ill. Adm. Code 211.7150

(2006); 40 C.F.R. 51.100(s) (2006) (the subsection pertaining to

tert

-butyl acetate does not

include this language). This could lead to confusion as to whether subsections (b) through (d)

apply to

tert

-butyl acetate listed in subsection (e). The Board has chosen not to revert to the

literal text of corresponding 40 C.F.R. 51.100(s)(1) because that text is imprecise and potentially

confusing.

Option B for correction of the text would retain

tert

-butyl acetate in the listing of

negligibly reactive compounds at subsection (a), with the addition of language that would direct

attention to subsection (e). This would eliminate the possibility for confusion of whether

subsections (b) through (d) apply to

tert

-butyl acetate. It would also minimize or eliminate the

possibility for confusion that

tert

-butyl acetate has a blanket, rather than a limited, exemption

from the definition of VOM. The Board perceives three basic methods for doing this.

---

5

Method 1 is the addition of a Board note that directs attention to subsection (e) for

limitations on the exemption of some compounds. The Board disfavors this approach, since the

Board note would necessarily be added at the end of the listing of negligibly reactive compounds

in subsection (a). This physical separation between the listing and the direction for limitations

could cause some readers to miss the reference to subsection (e).

Method 2 would involve adding a parenthetical reference to subsection (e) for limitations

on the exemption immediately after the listing for

tert

-butyl acetate. Using this approach, the

listing for

tert

-butyl acetate would appear as follows (with the newly added language

highlighted):

tertiary-Butyl acetate (subject to subsection (e) of this Section)

This would eliminate the possibility of missing the reference to subsection (e). The Board has

chosen not to use this method in favor of a third method suggested by the Agency.

Method 3 for directing attention to subsection (e) for limitations on the exemption of

tert

-

butyl acetate involves adding language to the preamble of subsection (a) that directs attention to

subsection (e). The Agency suggested this in the Issue Paper attached to PC 1. The Agency

suggested the following revisions to the preamble to subsection (a) (with deletions marked with

overstrike and additions underlined):

a)

This includes any such organic compound other than the following, which

have been determined by USEPA to have negligible photochemical

reactivity: The following listed compounds are not VOM for purposes of

VOM limitations or VOM content requirements. However, certain of

these compounds are considered VOM for purposes of recordkeeping,

emissions reporting, and inventory requirements, as described in

211.7150(e).

This approach would eliminate the possibility for confusion, but the Board believes that minor

adjustment of the suggested language could enhance the clarity of the preamble statement.

The Board amended Section 211.7150(a), using the approach described by the Agency,

but with minor modifications to the Agency-suggested language. The following revision will

clearly and concisely refer the regulated community to the limitations of subsection (e):

a)

This definition of VOM includes any such organic compound that

participates in atmospheric photochemical reactions, other than the

following compounds listed in this subsection (a), which have been

determined by USEPA to have negligible photochemical reactivity:.

USEPA has determined that the compounds listed in this subsection (a)

have negligible photochemical reactivity. USEPA has excluded the listed

negligibly-reactive compounds from the definition of VOM for purposes

of VOM limitations or VOM content requirements. However, USEPA has

required that certain of these compounds be considered VOM for purposes

---

6

of recordkeeping, emissions reporting, and inventory requirements, as

described in subsection (e) of this Section.

By the

Federal Register

notice of December 31, 2007 (at 72 Fed. Reg. 74250), the Board

received indirect comment from USEPA on the proposed amendments. Since the USEPA

comments in that notice so directly bear on the amendments in this docket, the Board has

docketed the

Federal Register

notice as PC 2 in this docket. By a notice of proposed rule,

USEPA proposed disapproval of the existing Illinois definition of VOM as amended by the

Board in Exemptions from the Definition of VOM, USEPA Amendments (July 1, 2004 through

December 31, 2004), R05-16 (May 19, 2005). Alternatively, USEPA proposed approval of the

Illinois definition of VOM if the Board would revise that definition in either of two alternative

ways. USEPA stated in its notice of proposed rule as follows:

Illinois added . . . t-butyl acetate to Title 35 of the Illinois Administration

Code Section 211.7150(a), its list of compounds exempt from VOC requirements.

It also added Section 211.7150(e), which provides the same unique requirements

for t-butyl acetate users as the EPA action did. It is not appropriate for t-butyl

acetate to be listed in 211.7150(a) because this compound is not exempt from all

VOC requirements as are the other compounds listed there. It should be listed in

211.7150(e) only, so the unique requirements for t-butyl acetate are clear. This

would follow the approach EPA took in making these revisions to the Federal

definition of VOC through separate actions.

EPA would find the requested revisions approvable if Illinois removes t-

butyl acetate from the list of compounds exempt from VOC requirements in

211.7150(a). This would leave it listed only under 211.7150(e) which makes it

clear what requirements apply to t-butyl acetate users. EPA would also find it

acceptable for Illinois to add a note to section 211.7150(a) that certain compounds

listed in section 211.7150(a) are subject to the requirements of 211.7150(e). This

would direct t-butyl acetate users to section 211.7150(e) where the special

requirements for this compound are stated. 72 Fed. Reg. at 74251.

The amendments as proposed by the Board on October 18, 2007 added a reference to the

limitations of subsection (e) to the listing for

tert

-butyl acetate in subsection (a). This was the

second option indicated in the

Federal Register

notice that USEPA would find acceptable.

At the public hearing conducted in this matter, the Agency stated its position relating to

the October 18, 2007 proposal, which was based on modifications to the Agency suggestions

included in PC 1. The Agency stated as follows at the hearing:

The Illinois EPA has reviewed the Board's order dated October 18, 2007, which

contained the proposed rule . . .. And specifically as to the modifications that

were made by the Board to the Agency suggested language, we do appreciate

those modifications and certainly we have no problem with the slightly revised

wording. So having reviewed the Board's October 18 order as well as the first

---

7

notice, the Agency has no concerns or objections as to the format and the content

of the proposed rule. Tr. at 5.

Since the corrective amendments included in the October 18, 2007 proposal for public

comment were acceptable to both USEPA and the Agency, the Board has adopted those

amendments as proposed. The Board has not altered the proposed amendments, except to add a

reference in the part source note to the recent adoption of amendments in docket R07-18, a

necessary correction to the base text indicated by JCAR, as indicated immediately below.

MISCELLANEOUS HOUSEKEEPING AMENDMENTS

In addition to the amendments related to USEPA’s actions, a limited number of

“housekeeping” amendments are adopted today. These changes are not based on the federal

amendments discussed above. Rather, these are corrections and clarifications needed in the

Board’s existing rule text involved in this rulemaking. These include the amendments that are

prompted by the USEPA objections to the existing text, discussed above. These also include

corrections made by JCAR in the course of preparing the proposal for publication in the

Illinois

Register

. The table below lists the Board’s “housekeeping” amendments.

HISTORICAL SUMMARY OF THE FEDERAL

RECOMMENDED

POLICY ON THE CONTROL OF VOLATILE ORGANIC COMPOUNDS

AND ITS IMPLEMENTATION IN ILLINOIS

Beginning in 1977, USEPA’s

Recommended Policy on the Control of Volatile Organic

Compounds

(Recommended Policy) exempt certain chemical compounds from the definition of

VOC or VOM.

1

These compounds were exempt due to their negligible photochemical reactivity

(

i.e.

, their reduced capacity for partaking in the complex atmospheric chemical reactions that

result in the formation in tropospheric ozone). Ultimately, in 1991, USEPA codified its

Recommended Policy in the

Code of Federal Regulations

at 40 C.F.R. 51.100(s) in its definition

of VOC.

Specifically, on July 8, 1977, USEPA established its Recommended Policy in the

Federal

Register

at 42 Fed. Reg. 35314. At that time, USEPA stated that the following compounds

should be exempt from regulation due to their negligible photochemical reactivity:

methane;

ethane;

methylene chloride (dichloromethane)

2

;

1,1,1-trichloroethane (methyl chloroform); and

trichlorotrifluoroethane (CFC-113 or Freon 113).

USEPA clarified its policy on June 4, 1979, at 44 Fed. Reg. 32043, and May 16, 1980, at 45 Fed.

Reg. 32424.

1

USEPA consistently uses the term “VOC” rather than “VOM,” but both designations refer to

the same matter. All references in this opinion and order to “VOM” refer to what USEPA calls

“VOC.”

2

USEPA’s July 8, 1977 discussion mentioned methylene chloride and several other compounds,

but none was included in either Table 1, which actually listed the recommended-exempt

compounds, and methylene chloride did not appear in Table 2, which listed low-reactivity

compounds. However, the June 4, 1979 and May 16, 1980 clarifications and later amendments

make it clear that USEPA considered methylene chloride exempt as of the initial publication of

the Recommended Policy on July 8, 1977.

---

9

USEPA later amended its Recommended Policy by adding exempt compounds. On July

22, 1980, at 45 Fed. Reg. 48941, USEPA added five chlorofluorocarbons (CFCs) and one

fluorocarbon (FC)

3

:

trichlorofluoromethane (CFC-11);

dichlorodifluoromethane (CFC-12);

chlorodifluoromethane (CFC-22);

trifluoromethane (FC-23);

dichlorotetrafluoroethane (CFC-114); and

chloropentafluoroethane (CFC-115).

On January 18, 1989, at 54 Fed. Reg. 1987, USEPA added four hydrohalocarbon

compounds (HFCs and HCFCs) to the list of those exempt:

dichlorotrifluoroethane (HCFC-123);

tetrafluoroethane (HFC-134a);

dichlorofluoroethane (HCFC-141b); and

chlorodifluoroethane (HCFC-142b).

Finally, on March 18, 1991, at 52 Fed. Reg. 11418, USEPA revisited certain compounds

earlier denied exemption and revised the Recommended Policy for the last time, to exclude five

additional hydrohalocarbon compounds and four classes of fluorocarbon compounds. The five

hydrohalocarbon compounds were:

2-chloro-1,1,1,2-tetrafluoroethane (HCFC-124);

pentafluoroethane (HFC-125);

1,1,2,2-tetrafluoroethane (HFC-134);

1,1,1-trifluoroethane (HFC-143a); and

1,1-difluoroethane (HFC-152a).

The four classes of fluorocarbon compounds were:

cyclic, branched, or linear, completely-fluorinated alkanes;

cyclic, branched, or linear, completely-fluorinated ethers with no unsaturations;

cyclic, branched, or linear, completely-fluorinated tertiary amines with no unsaturations;

and

sulfur-containing perfluorocarbons with no unsaturations and with sulfur bonds only to

carbon and fluorine.

3

This action purported to add trichlorotrifluoroethane (CFC-113), but that compound was

originally listed on July 8, 1977, although then given the parenthetical designation “Freon-113.”

That USEPA counted this single compound twice was further apparent in the action of January

18, 1989, discussed in the text below, when it referred to a list of exempt compounds that

included “eight additional chlorofluorocarbons (CFCs).”

---

10

On March 18, 1991, at 56 Fed. Reg. 11387, USEPA proposed codifying the

Recommended Policy in its definition of VOC at 40 C.F.R. 51.100(s). This proposed action was

undertaken in conjunction with the last amendments to the Recommended Policy discussed

above. USEPA adopted the amended definition of VOC on February 3, 1992, at 57 Fed. Reg.

3945. This USEPA codification included all the compounds and classes of compounds

previously included as exempt in the Recommended Policy. It also included test methods for

determining compliance with the VOC emissions limits, and a provision addressing situations

where the test method also measured exempt compounds.

USEPA subsequently amended the 40 C.F.R. 51.100(s) definition of VOM on a number

of occasions. Those are summarized as follows:

THE ILLINOIS DEFINITION OF VOM

Public Act 80-1299, effective August 2, 1978, added Section 9.1 to the Act. Subsection

(e) of Section 9.1 (formerly subsection (c)) requires the Board to incorporate exemptions into the

Illinois definition of VOM based on the federal exemptions. This provision required the Board

to use the Section 7.2 identical-in-substance procedure (exempt from Section 27 of the Act (415

ILCS 5/27 (2002) and the notice provisions of the APA) to incorporate the federal exemptions

into the Illinois definition of VOM.

The Board initially adopted the exemptions as part of Section 27 general rulemakings. In

dockets R78-3 and R78-4 (consolidated), on August 23, 1979, as part of the original Reasonably

Available Control Technology (RACT) rules, the Board adopted a definition of VOM that

excluded methane and ethane, expressly declining to exempt methylene chloride, 1,1,1-

trichloroethane, and CFC-113. In docket R80-5, on December 30, 1982, as part of the RACT II

rules, the Board added methylene chloride and 1,1,1-trichloroethane to the list of exempt

compounds. Finally, in docket R86-37, on December 22, 1987, the Board added the other six

CFC and one FC compounds that USEPA had excluded in its Recommended Policy up to that

date.

After that time, the Board repeatedly used the identical-in-substance procedure to

incorporate federal additions to the list of exempt compounds. In docket R89-8, on October 18,

1989, the Board amended the definition of VOM to exempt the additional compounds excluded

by USEPA on January 18, 1989. In docket R91-10, on September 12, 1991, the Board added the

one HCFC, four HFCs, and four classes of compounds exempt by USEPA on March 18, 1991.

In docket R91-24, on July 30, 1992, the Board further updated the Illinois definition of VOM for

purposes of the metropolitan Chicago and East St. Louis areas.

5

Beginning in 1992, with USEPA’s codification of the compounds excluded from VOC,

the Board had a way to readily determine the status of the list of exempt compounds: by

referring to the “List of Sections Affected” in the

Code of Federal Regulations

. At that time, the

5

The amendments in docket R91-24 extended the exemptions to the definitions of VOM

formerly found in 35 Ill. Adm. Code 218 and 219, which the Board added in dockets R91-7 and

R91-8, on July 25, 1991. However, in docket R93-9, on September 9, 1993, the Board

consolidated all definitions into 35 Ill. Adm. Code 211.

---

13

Board started treating the updates to the definition of VOM in the same manner that the Board

treats all other identical-in-substance subject matters. The Board began routinely reserving

dockets for each succeeding six-month period and specifically monitoring for federal revisions.

Accordingly, the Board has opened several dockets assigned to this subject matter, and the Board

has dismissed dockets when USEPA did not amend its definition in the relevant time-frame.

Before USEPA’s codification of excluded compounds, the Board relied on the Illinois

Environmental Protection Agency and the regulated community to specifically draw the Board’s

attention to any amendments to USEPA’s Recommended Policy. The Board has consistently

worked to ensure that the Illinois definition of VOM is the same as that used by USEPA, and that

any federal revisions are promptly reflected in the Illinois definition.

What follows is a summary listing of all Board dockets related to exemptions from the

definition of VOM. This table indicates the docket number of each proceeding, the date and

nature of the Board action on each docket, and the general subject matter of each. Those entries

that appear in bold italic amended the definition of VOM to exempt new compounds.

SUBPART B: DEFINITIONS

Section 211.7150

Volatile Organic Material (VOM) or Volatile Organic Compound (VOC)

“Volatile organic material”

(also “VOM”)” or “volatile organic compound” (also “VOC”)”

means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid,

metallic carbides or carbonates, and ammonium carbonate, that participates in atmospheric

photochemical reactions.

a)

This definition of VOM includes any such organic compound that participates in

atmospheric photochemical reactions, other than the following compounds listed

in this subsection (a), which have been determined by USEPA to have negligible

photochemical reactivity:. USEPA has determined that the compounds listed in

this subsection (a) have negligible photochemical reactivity. USEPA has

excluded the listed negligibly-reactive compounds from the definition of VOM

for purposes of VOM limitations or VOM content requirements. However,

USEPA has required that certain of these compounds be considered VOM for

purposes of recordkeeping, emissions reporting, and inventory requirements, as

described in subsection (e) of this Section.

32

Ill. Adm. Code 215.105, 218.112, and 219.112, as applicable, or by source-

specific test methods that have been established pursuant to a permit issued under

a program approved or promulgated under Title V of the Clean Air Act; under 40

CFR 51, Subpart I or Appendix S, incorporated by reference at 35 Ill. Adm. Code

218.112 and 219.112; or under 40 CFR 52.21, incorporated by reference at 35 Ill.

Adm. Code 218.112 and 219.112, as applicable. Where such a method also

measures compounds with negligible photochemical reactivity, these negligibly-

reactive compounds may be excluded as VOM if the amount of such compounds

is accurately quantified and the exclusion is approved by the Agency.

c)

As a precondition to excluding these negligibly-reactive compounds as VOM, or

at any time thereafter, the Agency may require an owner or operator to provide

monitoring or testing methods and results demonstrating, to the satisfaction of the

Agency, the amount of negligibly-reactive compounds in the source’s emissions.

d)

The USEPA will not be bound by any State determination as to appropriate

methods for testing or monitoring negligibly-reactive compounds if such

determination is not reflected in any of the test methods in subsection (b) above.

e)

The following compound is VOM for the purposes of all recordkeeping,

emissions reporting, photochemical dispersion modeling and inventory

requirements that apply to VOM, and it must be uniquely identified in emission

reports, but it is not VOM for the purposes of VOM emissions limitations or

VOM content requirements: t-butyl acetate.
