Federal Register / Vol. 86, No. 28 / Friday, February 12, 2021 / Proposed Rules 9307 

leave in place the basic framework of the SEF 

rules as originally adopted by the 

Commission. This framework has enhanced 

market transparency, improved competition, 

lowered transaction costs, and resulted in 

better swap prices for end users. While it 

may be appropriate to make other 

incremental changes going forward, it is 

important that we affirm the established 

regulatory program for SEFs to maintain 

these benefits and facilitate further expansion 

of this framework. 

I thank the staff of the Division of Market 

Oversight for their work on these two rules 

and their helpful engagement with my office.

Air Plan Approval; Illinois; Volatile 

Organic Material Definition Update 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is proposing to approve a 

revision to the Illinois State 

Implementation Plan (SIP). The revision 

will amend the Illinois Administrative 

Code (IAC) by updating the definition of 

volatile organic material (VOM) and 

volatile organic compounds (VOC) to 

exclude (Z)-1,1,1,4,4,4-hexafluorobut-2- 

ene. This revision is consistent with an 

EPA rulemaking in 2018, which 

exempted this compound from the 

Federal definition of VOC on the basis 

that the compound makes a negligible 

contribution to tropospheric ozone 

formation.

SUPPLEMENTARY INFORMATION: 

Throughout this document whenever 

‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean 

EPA. 

I. Background Information 

Tropospheric ozone, commonly 

known as smog, is formed when VOC 

and nitrogen oxides (NOX) react in the 

atmosphere in the presence of sunlight. 

Because of the harmful effects of ozone, 

EPA and state governments implement 

rules to limit the amount of certain VOC 

and NOX that can be released into the 

atmosphere. VOC are those compounds 

of carbon (excluding carbon monoxide, 

carbon dioxide, carbonic acid, metallic 

carbides or carbonates, and ammonium 

carbonate) that form ozone through 

atmospheric photochemical reactions. 

VOC have different levels of reactivity; 

they do not react at the same speed or 

form ozone to the same extent. 

The Clean Air Act (CAA) requires the 

regulation of VOC for various purposes. 

Section 302(s) of the CAA specifies that 

EPA has the authority to define the 

meaning of VOC, and hence, what 

compounds shall be treated as VOC for 

regulatory purposes. EPA’s longstanding 

policy is that compounds of carbon with 

negligible reactivity need not be 

regulated to reduce ozone and should be 

exempted from the regulatory definition 

of VOC. See 42 FR 35314 (July 8, 1977), 

70 FR 54046 (Sept. 13, 2005). 

EPA uses the reactivity of ethane as 

the threshold for determining whether a 

compound makes a negligible 

contribution to tropospheric ozone 

formation. Compounds that are less 

reactive than, or equally reactive to, 

ethane under certain assumed 

conditions may be deemed negligibly 

reactive and, therefore, suitable for 

exemption by EPA from the regulatory 

definition of VOC. EPA lists compounds 

it has determined to be negligibly 

reactive, and thus excluded from the 

regulatory definition of VOC, in 40 CFR 

51.100(s). 

On November 28, 2018, EPA added 

cis-1,1,1,4,4,4-hexafluorobut-2-ene (also 

known as HFO–1336mzz-Z; Chemical 

Abstract Service (CAS) RN 692–49–9), a 

hydrofluoroolefin, to the list of 

compounds excluded from the 

regulatory definition of VOC because it 

makes a negligible contribution to 

ground-level ozone formation. See 83 

FR 61127. 

II. The Illinois Submittal 

On October 20, 2020, the Illinois 

Environmental Protection Agency 

(IEPA) submitted amendments to 35 IAC 

211.7150 ‘‘Volatile Organic Material 

(VOM) or Volatile Organic Compound 

(VOC)’’ for approval as revisions to the 

Illinois SIP. Illinois’ SIP currently 

includes a definition of VOM at 35 IAC 

211.7150. See 81 FR 95475 (Dec. 28, 

2016). Subsection (a) of 35 IAC 211.7150 

includes a list of compounds excluded 

from the regulatory definition of VOC, 

which reflect some of the compounds 

EPA has excluded in 40 CFR 51.100(s), 

on the basis that they make a negligible 

contribution to tropospheric ozone 

formation. 

The proposed SIP revision updates 

the compounds excluded from the 

definition of VOM to conform to EPA’s 

recent exemption of a chemical 

compound from regulations of ozone 

precursors. Specifically, the SIP revision 

excludes (Z)-1,1,1,4,4,4-hexafluorobut2-ene from the definition of VOM or 

VOC at 35 IAC 211.7150. Illinois uses 

the International Union of Pure and 

Applied Chemistry (IUPAC) preferred 

name of (Z)-1,1,1,4,4,4-hexafluorobut-2- 

ene instead of cis-1,1,1,4,4,4- 

hexafluorobut-2-ene when addressing 

the compound. These changes do not 

interfere with the Federal listing of 

excluded compounds, and provide more 

specific chemical composition, 

structural, and isomeric identification 

information. Illinois also lists the 

compound by its other identifiers: HFO– 

1336mzz–Z and CAS No. 692–49–9. 

The Illinois Pollution Control Board 

(IPCB) held a public hearing on the 

proposed SIP revision on July 16, 2020. 

IPCB received three comments at the 

public hearing that resulted in no 

9308 Federal Register / Vol. 86, No. 28 / Friday, February 12, 2021 / Proposed Rules 

substantial changes to the amendment. 

IPCB also adopted minor administrative 

changes such as alphabetizing 

compound names and adopting IUPAC 

names for some compounds listed at 35 

IAC 211.7150. 

III. EPA’s Analysis of the Proposed SIP 

Revision 

In 2014, EPA received a petition 

requesting that cis-1,1,1,4,4,4- 

hexafluorobut-2-ene be exempted from 

VOC control based on its low reactivity, 

using ethane as a benchmark. Based on 

the mass maximum incremental 

reactivity value for the compound being 

less than that of ethane, EPA concluded 

that this compound makes negligible 

contributions to tropospheric ozone 

formation. Additionally, EPA 

considered risks not related to 

tropospheric ozone associated with 

currently allowed uses of the chemical 

to be acceptable. As a result, on 

November 28, 2018, EPA responded to 

the petition by amending 40 CFR 

51.100(s) to exclude this chemical 

compound from the definition of VOC 

for purposes of preparing SIPs to attain 

the national ambient air quality 

standard for ozone under title I of the 

CAA. See 83 FR 61127 (Nov. 28, 2018). 

EPA’s action became effective on 

January 28, 2019. 

By excluding cis-1,1,1,4,4,4- 

hexafluorobut-2-ene from the definition 

of VOM at 35 IAC 211.7150, Illinois’ 

proposed SIP revision is consistent with 

EPA’s action amending the definition of 

VOC at 40 CFR 51.100(s). 

IV. What action is EPA taking? 

EPA is proposing to approve the 

revision to the Illinois SIP at 35 IAC 

211.7150 submitted on October 20, 

2020. The proposed approval of the 

revision meets the criteria of the CAA 

and applicable Federal regulations. 

V. Incorporation by Reference 

In this rule, EPA is proposing to 

include in a final EPA rule regulatory 

text that includes incorporation by 

reference. In accordance with 

requirements of 1 CFR 51.5, EPA is 

proposing to incorporate by reference 

revisions to 35 IAC 211.7150 ‘‘Volatile 

Organic Material (VOM) or Volatile 

Organic Compound (VOC)’’, effective 

August 18, 2020. EPA has made, and 

will continue to make, these documents 

generally available through 

www.regulations.gov and at the EPA 

Region 5 Office (please contact the 

person identified in the FOR FURTHER

INFORMATION CONTACT section of this 

preamble for more information). 

VI. Statutory and Executive Order 

Reviews 

Under the CAA the Administrator is 

required to approve a SIP submission 

that complies with the provisions of the 

CAA and applicable Federal regulations. 

42 U.S.C. 7410(k); 40 CFR 52.02(a). 

Thus, in reviewing SIP submissions, 

EPA’s role is to approve state choices, 

provided that they meet the criteria of 

the CAA. Accordingly, this action 

merely approves state law as meeting 

Federal requirements and does not 

impose additional requirements beyond 

those imposed by state law. For that 

reason, this action: 

• Is not a significant regulatory action 

subject to review by the Office of 

Management and Budget under 

Executive Orders 12866 (58 FR 51735, 

October 4, 1993) and 13563 (76 FR 3821, 

January 21, 2011); 

• Is not an Executive Order 13771 (82 

FR 9339, February 2, 2017) regulatory 

action because SIP approvals are 

exempted under Executive Order 12866; 

• Does not impose an information 

collection burden under the provisions 

of the Paperwork Reduction Act (44 

U.S.C. 3501 et seq.); 

• Is certified as not having a 

significant economic impact on a 

substantial number of small entities 

under the Regulatory Flexibility Act (5 

U.S.C. 601 et seq.); 

• Does not contain any unfunded 

mandate or significantly or uniquely 

affect small governments, as described 

in the Unfunded Mandates Reform Act 

of 1995 (Pub. L. 104–4); 

• Does not have federalism 

implications as specified in Executive 

Order 13132 (64 FR 43255, August 10, 

1999); 

• Is not an economically significant 

regulatory action based on health or 

safety risks subject to Executive Order 

13045 (62 FR 19885, April 23, 1997); 

• Is not a significant regulatory action 

subject to Executive Order 13211 (66 FR 

28355, May 22, 2001); 

• Is not subject to requirements of 

Section 12(d) of the National 

Technology Transfer and Advancement 

Act of 1995 (15 U.S.C. 272 note) because 

application of those requirements would 

be inconsistent with the Clean Air Act; 

and 

• Does not provide EPA with the 

discretionary authority to address, as 

appropriate, disproportionate human 

health or environmental effects, using 

practicable and legally permissible 

methods, under Executive Order 12898 

(59 FR 7629, February 16, 1994). 

In addition, the SIP is not approved 

to apply on any Indian reservation land 

or in any other area where EPA or an 

Indian tribe has demonstrated that a 

tribe has jurisdiction. In those areas of 

Indian country, the rule does not have 

tribal implications and will not impose 

substantial direct costs on tribal 

governments or preempt tribal law as 

specified by Executive Order 13175 (65 

FR 67249, November 9, 2000).
