These revisions concern emissions of volatile organic compounds (VOCs) and oxides of nitrogen (NO <E T="52">X</E> ) from refinery flares. We are proposing action on a local rule to regulate these emission sources under the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action. </SUM> <EFFDATE> <HD SOURCE="HED">DATES:</HD> Comments must be received on or before April 8, 2024. </EFFDATE> <HD SOURCE="HED">ADDRESSES:</HD> Submit your comments, identified by Docket ID No. EPA-R09-OAR-2023-0568 at <E T="03">https://www.regulations.gov.</E> For comments submitted at <E T="03">Regulations.gov</E> , follow the online instructions for submitting comments.

What rule did the State submit?</HD> Table 1 lists the rule addressed by this proposal with the dates that it was adopted by the local air agency and submitted by the California Air Resources Board (CARB). <GPOTABLE COLS="5" OPTS="L2,i1" CDEF="s25,12C,r75,12C,12C"> <TTITLE>Table 1—Submitted Rule</TTITLE> <CHED H="1">Local agency</CHED> <CHED H="1">Rule No.</CHED> <CHED H="1">Rule title</CHED> <CHED H="1">Amended</CHED> <CHED H="1">Submitted</CHED> <ROW> <ENT I="01">SCAQMD</ENT> <ENT>1118</ENT> <ENT>Control of Emissions from Refinery Flares</ENT> <ENT>01/06/23</ENT> <ENT>05/11/23</ENT> </ROW> </GPOTABLE> On November 11, 2023, the submittal for SCAQMD Rule 1118 was deemed by operation of law to meet the completeness criteria in 40 CFR part 51 Appendix V, which must be met before formal EPA review. <HD SOURCE="HD2">B. Are there other versions of this rule?</HD> On September 22, 2022, in a limited approval and limited disapproval action, the EPA finalized inclusion of an earlier version of Rule 1118 into the SIP (87 FR 57838). The SCAQMD adopted revisions to the SIP-approved version of Rule 1118 on January 6, 2023, and CARB submitted them to us on May 11, 2023. If we finalize our proposed approval, the January 6, 2023 version of Rule 1118 will replace the previously approved version of this rule in the SIP. <HD SOURCE="HD2">C. What is the purpose of the submitted rule?</HD> Emissions of NO <E T="52">X</E> and VOCs contribute to the production of ground-level ozone, smog and particulate matter (PM), which harm human health and the environment. Section 110(a) of the CAA requires states to submit regulations that control NO <E T="52">X</E> and VOC emissions. Rule 1118 Control of Emissions from Refinery Flares is designed to monitor and record data on refinery and related flaring operations, and to control and minimize flaring and flare related emissions. The EPA's technical support document (TSD) for this action has more information about this rule. <HD SOURCE="HD1">II. The EPA's Evaluation and Action</HD> <HD SOURCE="HD2">A. How is the EPA evaluating the rule?</HD> Rules in the SIP must be enforceable (see CAA section 110(a)(2)), must not interfere with applicable requirements concerning attainment and reasonable further progress or other CAA requirements (see CAA section 110(l)), and must not modify certain SIP control requirements in nonattainment areas without ensuring equivalent or greater emissions reductions (see CAA section 193). Generally, SIP rules must require reasonably available control technology (RACT) for each category of sources covered by a Control Techniques Guidelines (CTG) document as well as each major source of NO <E T="52">X</E> and VOCs in ozone nonattainment areas classified as moderate or above (see CAA section 182(b)(2)). The SCAQMD regulates an ozone nonattainment area classified as “Extreme” for the 2015 8-hour ozone NAAQS (40 CFR 81.305). Therefore, this rule must ensure the applicable sources implement RACT-level controls for that ozone standard. Our September 22, 2022 action on Rule 1118 evaluated the rule using this criteria. We finalized a limited approval and limited disapproval of Rule 1118 (amended July 7, 2017) on the basis that the rule allowed the Executive Officer the authority to approve other test methods for determining compliance than those identified in the rule. This deficiency undermined the enforceability of the rule by allowing revisions to the requirements in the SIP without the EPA's approval. In this current action, Rule 1118 was amended by SCAQMD to solely address the limited disapproval. The changes to Rule 1118 in this submittal have not relaxed or removed any of the main stringency rule provisions, including control requirements, nor have we identified any new information to alter our prior evaluation of Rule 1118. Therefore, our evaluation of the January 6, 2023 amended version of Rule 1118 is focused on the correction of the previously identified deficiency. Guidance and policy documents that we used to evaluate enforceability and revision/relaxation requirements for the applicable criteria pollutants include the following: 1. “State Implementation Plans; General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990,” 57 FR 13498 (April 16, 1992); 57 FR 18070 (April 28, 1992). 2. “Issues Relating to VOC Regulation Cutpoints, Deficiencies, and Deviations,” EPA, May 25, 1988 (the Bluebook, revised January 11, 1990). 3. “Guidance Document for Correcting Common VOC & Other Rule Deficiencies,” EPA Region 9, August 21, 2001 (the Little Bluebook). <HD SOURCE="HD2">B. Does the rule meet the evaluation criteria?</HD> The revisions to Rule 1118 in this submittal correct the deficiency identified in the EPA's previous limited approval and limited disapproval of the rule. The new version of Rule 1118 improves the SIP by including the EPA as an approving authority for use of alternative test methods when determining rule compliance. The rule is now largely consistent with CAA requirements and relevant guidance regarding enforceability, RACT, and SIP revisions, and fully approvable. <HD SOURCE="HD2">C. The EPA's Recommendations To Further Improve the Rule</HD> The TSD includes recommendations for the next time SCAQMD modifies the rule. <HD SOURCE="HD2">D. Public Comment and Proposed Action</HD> As authorized in section 110(k)(3) of the Act, the EPA proposes to fully approve the submitted rule because it fulfill(s) all relevant requirements. We will accept comments from the public on this proposal until April 8, 2024. If we approve the submitted rule in our final action, then will incorporate this rule into the federally enforceable SIP. <HD SOURCE="HD1">III. Incorporation by Reference</HD> In this rule, the 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, the EPA is proposing to incorporate by reference the SCAQMD rule listed in Table 1 of this preamble, which is desi ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Preview showing 10k of 15k characters.
