Proposed Rule. Proposal for Public Comment.
 
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 a proposal for public comment that would 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) as necessary for federal authorization.
 
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 will not adopt a “First Notice” proposal, or a “Second Notice” proposal for review by the Joint Committee on Administrative Rules. However, as provided in Section 9.1(e) of the Act, the Board, before adopting final rule amendments, will provide notice of this rulemaking proposal in the Illinois Register, hold one public hearing on the proposal as required by the federal Clean Air Act (33 U.S.C. § 7410(a) (2005)), and allow for public comment.
 
In this opinion, the Board first sets forth the timetable for completing this rulemaking, followed by a description of the USEPA action necessitating these rule amendments. The Board then provides information on the hearing and public comment period for this proceeding. Finally, the Board summarizes the history of federal and Illinois actions dealing with VOM exemptions. The Board’s proposed rule amendments to the definition of VOM are set forth in the order following this opinion.
 



TIMETABLE FOR COMPLETING THIS RULEMAKING
 

Under Section 7.2(b) of the Act (415 ILCS 5/7.2(b) (2006)), the Board must complete this rulemaking within one year after the date of the earliest set of federal amendments considered in this docket. USEPA adopted such amendments on January 18, 2007. Therefore, the deadline for the Board to adopt these amendments is January 18, 2008.
 
The Board scheduled the adoption of this “proposal for public comment” ahead of the date projected as necessary to timely complete this rulemaking. This will allow the Board to adopt final rules approximately six months before the one-year deadline. This scheduling will give the regulated community the earliest opportunity to use the newly-exempt compound, and allow the State to take advantage as soon as possible of the emissions inventory and improved air quality benefits that may accrue through the new exemption.
 
The Board projects the following timetable in completing this rulemaking:
 
Due date: January 18, 2008
Date of Board vote to propose amendments: October 18, 2007
Submission for Illinois Register publication: October 22, 2007
Probable Illinois Register publication date: November 2, 2007
Public hearing date: December 5, 2007
Probable end of 45-day public comment period: December 17, 2007
Date of Board vote to adopt amendments: December 20, 2007
Probable filing and effective date: December 31, 2007
Probable Illinois Register publication date: January 11, 2008



DESCRIPTION OF USEPA ACTIONS AND BOARD AMENDMENTS
 

The amendments proposed 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, which 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 it has the empirical formula C2F5CF(OCH3)CF(CF3)2. 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 proposes to incorporate 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 proposed deviations from the federal text.
 



Deviations from the Text of the Federal Amendments
 
Illinois Section 40 C.F.R. Section Revision(s)
211.7150(a) “HFE-7300” 51.100(s)(1) Located the compound in alphabetical name order; removed the parenthetical “(1)” from before the chemical name; capitalized the chemical name; added the alternative chemical designation “L-14787” and the empirical formula “C2F5CF(OCH3)CF(CF3)2”



Correction of the Existing Text of the Definition of VOM
 

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 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.
 
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 has chosen to amend Section 211.7150(a), using the approach described by the Agency, but with minor modifications to the Agency-suggested language. The following revision selected by the Board 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 of recordkeeping, emissions reporting, and inventory requirements, as described in subsection (e) of this Section.

MISCELLANEOUS HOUSEKEEPING AMENDMENTS
 

In addition to the proposed amendments related to USEPA’s actions, a limited number of “housekeeping” amendments are being proposed today. These proposed 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 proposal. These include the amendments that are prompted by the USEPA objections to the existing text, discussed above. The table below lists the Board’s proposed “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.
 
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.
 
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:

HISTORICAL SUMMARY OF EXCLUSIONS FROM



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 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.

b) For purposes of determining VOM emissions and compliance with emissions limits, VOM will be measured by the test methods in the approved implementation plan or 40 CFR 60, Appendix A, incorporated by reference at 35 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.
