Environmental Protection Agency (EPA).
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Georgia through the Georgia Environmental Protection Division on October 18, 2019. This revision modifies the State's air quality regulations as incorporated into the SIP by changing the definition of “volatile organic compound” (VOC) to be consistent with federal regulations. EPA is proposing to approve this SIP revision because the State has demonstrated that these changes are consistent with the Clean Air Act (CAA or Act).
Comments must be received on or before June 1, 2020.
Submit your comments, identified by Docket ID No. EPA-R04-OAR-2020-0069 at www.regulations.gov. Follow the online instructions for submitting comments. Once submitted, comments cannot be edited or removed from Regulations.gov. EPA may publish any comment received to its public docket. Do not submit electronically any information you consider to be Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. Multimedia submissions (audio, video, etc.) must be accompanied by a written comment. The written comment is considered the official comment and should include discussion of all points you wish to make. EPA will generally not consider comments or comment contents located outside of the primary submission (i.e., on the web, cloud, or other file sharing system). For additional submission methods, the full EPA public comment policy, information about CBI or multimedia submissions, and general guidance on making effective comments, please visit www2.epa.gov/dockets/commenting-epa-dockets.

Start Supplemental Information
EPA is proposing to approve the change to the Georgia SIP submitted by the State of Georgia through a letter dated October 18, 2019 
that revises the definition of “volatile organic compound” at subparagraph (llll) of Rule 391-3-1-.01—“Definitions” by adding cis-1,1,1,4,4,4-hexafluorobut-2-ene (HFO-1336mzz-Z) to the list of organic compounds having negligible photochemical reactivity.
II. Analysis of State Submission
Tropospheric ozone, commonly known as smog, occurs when VOC and nitrogen oxides (NOX) react in the atmosphere in the presence of sunlight. Because of the harmful health 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 have different levels of reactivity; they do not react at the same speed or form ozone to the same extent. The 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” under the Act and, hence, what compounds shall be treated as VOC for regulatory purposes.
EPA determines whether a given carbon compound has “negligible” reactivity by comparing the compound's reactivity to the reactivity of ethane. It is EPA's policy that compounds of carbon with negligible reactivity be excluded from the regulatory definition of VOC. See 42 FR 35314 (July 8, 1977), 70 FR 54046 (September 13, 2005). EPA lists these compounds in its regulations at 40 CFR 51.100(s) and excludes them from the definition of VOC. The chemicals on this list are often called “negligibly reactive.” EPA may periodically revise the list of negligibly reactive compounds to add or delete compounds. Georgia submitted this SIP revision in response to EPA adding cis-1,1,1,4,4,4-hexafluorobut-2-ene to the exclusion list at 40 CFR 51.100(s). See 83 FR 61127 (January 28, 2019). EPA proposes to find that this change to the SIP will not interfere with attainment or maintenance of any national ambient air quality standard, reasonable further progress, or any other applicable requirement of the CAA, consistent with CAA section 110(l), because EPA has found this chemical to be negligibly reactive.
III. Incorporation by Reference
In this document, 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 Georgia Rule 391-3-1-.01—“Definitions,” Subparagraph (llll)—“Volatile organic compound,” state-effective September 26, 2019, to revise this definition by adding cis-1,1,1,4,4,4- hexafluorobut-2-ene (HFO-1336mzz-Z) to the list of organic compounds having negligible photochemical reactivity. EPA has made, and will continue to make, these materials generally available through www.regulations.gov and at the EPA Region 4 office (please contact the person identified in the For Further Information Contact section of this preamble for more information).
IV. Proposed Action
EPA is proposing to approve Georgia's October 18, 2019 SIP submission that revises the definition of “volatile organic compound” at Rule 391-3-1-Start Printed Page 25382.01(llll) to be consistent with federal regulations and CAA requirements.
V. Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. See 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. This action merely proposes to approve state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action:
Start List of Subjects
- 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 1955 (Pub. L. 104-4);
- Does not have Federalism implications as specified in the 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 CAA; 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). The SIP is not approved to apply on any Indian reservation land or 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 as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it impose substantial direct costs on tribal governments or preempt tribal law.
