Supplementary Information

A. Chapter No. 335-3-1, General Provisions

Tropospheric ozone 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 do not form ozone to the same extent. Section 302(s) of the Clean Air Act (CAA or Act) 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 determines whether a given carbon compound has ``negligible'' reactivity by comparing the compound's reactivity to the reactivity of ethane. EPA's longstanding policy is that compounds of carbon with negligible reactivity need not be regulated to reduce ozone and should 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. EPA last approved the aforementioned compounds listed in Alabama Administrative Code Rule 335-3-1-.02(1)(gggg) ``Volatile Organic Compounds (VOC)'' on September 21, 2020. See 85 FR 59192. EPA is proposing to approve the change to the Alabama SIP submitted by [[Page 11501]] the State of Alabama through a letter dated December 20, 2023, that revises the definition of VOC by adding ``trans-1,1,1,4,4,4 hexafluorobut-2-ene (HFO-1336mzz(E))'' to the list of organic compounds that are not considered VOCs. This is done in accordance with EPA's revision of its VOC definition at 40 CFR 51.100(s) on February 8, 2023. See 88 FR 8226. EPA proposes to find that this change to the SIP will not interfere with attainment or maintenance of any national ambient air quality standards, 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.

B. Chapter No. 335-3-5, Control of Sulfur Compound Emissions

Alabama Administrative Code Rules 335-3-5-.06 through 335-3-5-.36, were initially approved into the Alabama SIP on August 31, 2016. See 81 FR 59869. That rulemaking approved Alabama's Transport Rule (TR) sulfur dioxide (SO2) Group 2 Trading Program requiring Alabama EGUs to participate in new Cross-State Air Pollution Rule (CSAPR) State trading programs for annual SO2 emissions integrated with the CSAPR Federal trading programs, replacing the corresponding Federal implementation plan (FIP) requirements. The December 20, 2023, submittal removes the text ``(1) General'', ``(1)'', or ``General'' from the beginning of the following rules to be in line with Alabama's Legislative Services Agency requirements: 335-3- 5-.10, TR SO2 Trading Program--Computation of Time; 335-3-5-.11, Administrative Appeal Procedures; 335-3-5-.14, Authorization of Designated Representative and Alternate Designated Representative; 335- 3-5-.15, Responsibilities of Designated Representative and Alternate Designated Representative; 335-3-5-.16, Changing Designated Representative and Alternate Designated Representative; Changes in Owners and Operators; Changes in Units at the Source; 335-3-5-.17, Certificate of Representation; 335-3-5-.19, Delegation by Designated Representative and Alternate Designated Representative; 335-3-5-.22, Recordation of TR SO2 Allowance Allocations and Auction Results; 335-3- 5-.23, Submission of TR SO2 Allowance Transfers; 335-3-5-.24, Recordation of TR SO2 Allowance Transfers; 335-3-5-.25, Compliance with TR SO2 Emissions Limitation; 335-3-5-.26, Compliance with TR SO2 Assurance Provisions; 335-3-5-.28, Account Error; 335-3-5-.29, Administrator's Action on Submissions; 335-3-5-.33, Monitoring System Out-of-Control Periods; 335-3-5-.34, Notifications Concerning Monitoring; 335-3-5-.35, Recordkeeping and Reporting; and 335-3-5-.36, Petitions for Alternatives to Monitoring, Recordkeeping, or Reporting Requirements. EPA proposes to find that these changes 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 they are administrative in nature.

C. Chapter No. 335-3-8, Nitrogen Oxides Emissions

EPA initially approved ADEM Administrative Code Rules 335-3-8-.07 through 335-3-5-.38 into the Alabama SIP on August 31, 2016. See 81 FR 59869. These rules pertain to Alabama's TR nitrogen oxides (NOX) Annual Trading Program requiring Alabama Electricity Generating Units (EGUs) to participate in new CSAPR State trading programs for annual NOX emissions integrated with the CSAPR Federal trading programs, replacing the corresponding FIP requirements. The December 20, 2023, submittal removes the text ``(1) General'', ``(1)'', or ``General'' from the beginning of the following rules to be in line with Alabama's Legislative Services Agency requirements: 335-3- 8-.11, TR NOX Annual Trading Program--Computation of Time, 335-3-8-.12 Administrative Appeal Procedures, 335-3-8-.16, Authorization of Designated Representative and Alternate Designated Representative; 335- 3-8-.17, Responsibilities of Designated Representative and Alternate Designated Representative; 335-3-8-.18 Changing Designated Representative and Alternate Designated Representative; Changes in Owners and Operators; Changes in Units at the Source; 335-3-8-.19, Certificate of Representation; 335-3-8-.21, Delegation by Designated Representative and Alternate Designated Representative; 335-3-8-.24, Recordation of TR NOX Annual Allowance Allocations and Auction Results; 335-3-8-.25, Submission of TR NOX Annual Allowance Transfers; 335-3- 8-.26, Recordation of TR NOX Annual Allowance Transfers; 335-3-8-.27, Compliance with TR NOX Annual Emissions Limitation; 335-3-8-.28, Compliance with TR NOX Annual Assurance Provisions; 335-3-8-.30, Account Error; 335-3-8-.31, Administrator's Action on Submissions, 335- 3-8-.35, Monitoring System Out-of-Control Periods; 335-3-8-.36, Notifications Concerning Monitoring; 335-3-8-.37, Recordkeeping and Reporting; and 335-3-8-.38, Petitions for Alternatives to Monitoring, Recordkeeping, or Reporting Requirements. EPA initially approved ADEM Administrative Code Rules 335-3-8-.39 through 335-3-8-.70 on October 6, 2017. See 82 FR 46674. These rules pertain to Alabama's TR NOX Ozone Season Trading Program requiring Alabama EGUs to participate in new CSAPR State trading programs for ozone season NOX emissions integrated with the CSAPR Federal trading programs, replacing the corresponding FIP requirements. The December 20, 2023, submittal removes the text ``(1) General'', ``(1)'', or ``General'' from the beginning of the following rules to be in line with Alabama's Legislative Services Agency requirements: 335-3-8-.43, TR NOX Ozone Season Group 2 Trading Program--Computation of Time; 335-3-8-.44, Administrative Appeal Procedures; 335-3-8-.48, Authorization of Designated Representative and Alternate Designated Representative; 335-3-8-.49, Responsibilities of Designated Representative and Alternate Designated Representative; 335- 3-8-.50, Changing Designated Representative and Alternate Designated Representative; Changes in Owners and Operators; Changes in Units at the Source; 335-3-8-.51, Certificate of Representation; 335-3-8-.53, Delegation by Designated Representative and Alternate Designated Representative; 335-3-8-.56, Recordation of TR NOX Ozone Season Group 2 Allowance Allocations and Auction Results; 335-3-8-.57, Submission of TR NOX Ozone Season Group 2 Allowance Transfers; 335-3-8-.58, Recordation of TR NOX Ozone Season Group 2 Allowance Transfers; 335-3- 8-.59, Compliance with TR NOX Ozone Season Group 2 Emissions Limitation; 335-3-8-.60, Compliance with TR NOX Ozone Season Group 2 Assurance Provisions; 335-3-8-.62, TR NOX Ozone Season Group 2 Trading Program--Account Error; 335-3-8-.63, TR NOX Ozone Season Group 2 Trading Program--Administrator's Action on Submissions; 335-3-8-.67, Monitoring System Out-of-Control Periods; 335-3-8-.68, Notifications Concerning Monitoring; 335-3-8-.69, Recordkeeping and Reporting; and 335-3-8-.70, Petitions for Alternatives to [[Page 11502]] Monitoring, Recordkeeping, or Reporting Requirements. EPA initially approved Alabama Administrative Code Rule 335-3- 8-.71, ``NOX Budget Program,'' on July 7, 2021. See 86 FR 35610. This rule reestablished enforceable limits on ozone season NOX mass emissions for certain sources as required by EPA's NOX SIP Call regulations. In Rule 335-3-8-.71, the text ``[New Rule]'' is removed from the title line, to be consistent with Alabama's Legislative Services Agency requirements. EPA proposes to find that these changes 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 they are administrative in nature.

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, and as discussed in Section I of this preamble, EPA is proposing to incorporate by reference Alabama Administrative Code Rule 335-3-1-.02, Definitions; Rules 335-3-5-.10, TR SO2 Trading Program--Computation of Time; 335-3-5-.11, Administrative Appeal Procedures; 335-3-5-.14, Authorization of Designated Representative and Alternate Designated Representative; 335- 3-5-.15, Responsibilities of Designated Representative and Alternate Designated Representative; 335-3-5-.16, Changing Designated Representative and Alternate Designated Representative; Changes in Owners and Operators; Changes in Units at the Source; 335-3-5-.17, Certificate of Representation; 335-3-5-.19, Delegation by Designated Representative and Alternate Designated Representative; 335-3-5-.22, Recordation of TR SO2 Allowance Allocations and Auction Results; 335-3- 5-.23, Submission of TR SO2 Allowance Transfers; 335-3-5-.24, Recordation of TR SO2 Allowance Transfers; 335-3-5-.25, Compliance with TR SO2 Emissions Limitation; 335-3-5-.26, Compliance with TR SO2 Assurance Provisions; 335-3-5-.28, Account Error; 335-3-5-.29, Administrator's Action on Submissions; 335-3-5-.33, Monitoring System Out-of-Control Periods; 335-3-5-.34, Notifications Concerning Monitoring; 335-3-5-.35, Recordkeeping and Reporting; and 335-3-5-.36, Petitions for Alternatives to Monitoring, Recordkeeping, or Reporting Requirements; and Rules 335-3-8-.11, TR NOX Annual Trading Program-- Computation of Time, 335-3-8-.12 Administrative Appeal Procedures, 335- 3-8-.16, Authorization of Designated Representative and Alternate Designated Representative; 335-3-8-.17, Responsibilities of Designated Representative and Alternate Designated Representative; 335-3-8-.18 Changing Designated Representative and Alternate Designated Representative; Changes in Owners and Operators; Changes in Units at the Source; 335-3-8-.19, Certificate of Representation; 335-3-8-.21, Delegation by Designated Representative and Alternate Designated Representative; 335-3-8-.24, Recordation of TR NOX Annual Allowance Allocations and Auction Results; 335-3-8-.25, Submission of TR NOX Annual Allowance Transfers; 335-3-8-.26, Recordation of TR NOX Annual Allowance Transfers; 335-3-8-.27, Compliance with TR NOX Annual Emissions Limitation; 335-3-8-.28, Compliance with TR NOX Annual Assurance Provisions; 335-3-8-.30, Account Error; 335-3-8-.31, Administrator's Action on Submissions, 335-3-8-.35, Monitoring System Out-of-Control Periods; 335-3-8-.36, Notifications Concerning Monitoring; 335-3-8-.37, Recordkeeping and Reporting; 335-3-8-.38, Petitions for Alternatives to Monitoring, Recordkeeping, or Reporting Requirements; 335-3-8-.43, TR NOX Ozone Season Group 2 Trading Program--Computation of Time; 335-3-8-.44, Administrative Appeal Procedures; 335-3-8-.48, Authorization of Designated Representative and Alternate Designated Representative; 335-3-8-.49, Responsibilities of Designated Representative and Alternate Designated Representative; 335- 3-8-.50, Changing Designated Representative and Alternate Designated Representative; Changes in Owners and Operators; Changes in Units at the Source; 335-3-8-.51, Certificate of Representation; 335-3-8-.53, Delegation by Designated Representative and Alternate Designated Representative; 335-3-8-.56, Recordation of TR NOX Ozone Season Group 2 Allowance Allocations and Auction Results; 335-3-8-.57, Submission of TR NOX Ozone Season Group 2 Allowance Transfers; 335-3-8-.58, Recordation of TR NOX Ozone Season Group 2 Allowance Transfers; 335-3- 8-.59, Compliance with TR NOX Ozone Season Group 2 Emissions Limitation; 335-3-8-.60, Compliance with TR NOX Ozone Season Group 2 Assurance Provisions; 335-3-8-.62, TR NOX Ozone Season Group 2 Trading Program--Account Error; 335-3-8-.63, TR NOX Ozone Season Group 2 Trading Program--Administrator's Action on Submissions; 335-3-8-.67, Monitoring System Out-of-Control Periods; 335-3-8-.68, Notifications Concerning Monitoring; 335-3-8-.69, Recordkeeping and Reporting; 335-3- 8-.70, Petitions for Alternatives to Monitoring, Recordkeeping, or Reporting Requirements; and 335-3-8-.71, NOX Budget Program, State effective February 12, 2024, which address typographical errors and increase clarity and consistency with EPA's definitions and Alabama's Legislative Services Agency requirements. 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).

III. Proposed Action

EPA is proposing to approve Alabama's December 20, 2023, SIP revision consisting of the aforementioned changes to Chapter No. 335-3- 1, General Provisions; Chapter No. 335-3-5, Control of Sulfur Compound Emissions; and Chapter No. 335-3-8, Nitrogen Oxides Emissions because they are consistent with CAA requirements. Thus, EPA is proposing to incorporate these changes into Alabama's SIP.

IV. 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. 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. Accordingly, this proposed 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: Is not a significant regulatory action subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993); Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); [[Page 11503]] 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 subject to Executive Order 13045 (62 FR 19885, April 23, 1997) because it approves a State program; Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); and 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. 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 proposed 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). List of Subjects in 40 CFR Part 52 Environmental protection, Air pollution control, Incorporation by reference, Nitrogen dioxide, Ozone, Reporting and recordkeeping requirements, Sulfur oxides, Volatile organic compounds. Authority: 42 U.S.C. 7401 et seq. Dated: February 21, 2025. Jeaneanne Gettle, Acting Regional Administrator, Region 4. [FR Doc. 2025-03608 Filed 3-6-25; 8:45 am] BILLING CODE 6560-50-P
