ACTION: Final rule; partial stay. ----------------------------------------------------------------------- SUMMARY: By a letter dated August 14, 2024, and supplemented by a letter dated March 5, 2025, the EPA's Office of Air and Radiation announced the convening of a proceeding for reconsideration of certain requirements in the final rule, ``National Emission Standards for Hazardous Air Pollutants: Integrated Iron and Steel Manufacturing Facilities Technology Review,'' published on April 3, 2024. In this action, the EPA is staying provisions establishing compliance deadlines in 2025 for requirements that were added or revised by the April 3, 2024, final rule for 90 days pending reconsideration.

Background On April 3, 2024, the EPA completed a technology review under Clean Air Act (CAA) section 112(d)(6) of the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Integrated Iron and Steel Manufacturing Facilities that revised standards that were issued in 2003 and reviewed in 2020. Additionally, EPA set standards under CAA sections 112(d)(2) and 112(d)(3) for previously unregulated hazardous air pollutant emissions. The NESHAP amendments are codified at 40 CFR part 63, subpart FFFFF. For further information on the 2024 rule, see 89 FR 23294 (April 3, 2024). On June 3 and 4, 2024, several interested parties submitted administrative petitions to the EPA seeking reconsideration of various aspects of the 2024 rule pursuant to section 307(d)(7)(B) of the CAA (42 U.S.C. 7607(d)(7)(B)). Copies of these petitions are included in the docket, Docket ID No. EPA-HQ-OAR-2002-0083. On August 14, 2024, the EPA issued a letter stating our intention to exercise our discretion to reconsider three issues raised in the petitions, address some items of correction, and continue reviewing the petitions for reconsideration. Later, on March 5, 2025, the EPA issued a second letter modifying the scope of the already convened discretionary reconsideration proceeding by identifying some items from the petitions for reconsideration as appropriate for mandatory reconsideration based on the criteria in CAA section 307(d)(7)(B). Copies of both EPA response letters are included in the docket, Docket ID No. EPA-HQ-OAR-2002-0083. Under CAA section 307(d)(7)(B), 42 U.S.C. 7607(d)(7)(B), the Administrator shall convene a proceeding for reconsideration of a rule when the person raising an objection to a rule can demonstrate: (1) that it was either impractical to raise the objection during the period for public comment or that the grounds for the objection arose after the period for public comment; and (2) that the objection is of central relevance to the outcome of the rule. The March 5, 2025 letter announced that, in addition to the discretionary reconsideration issues identified in the August 14, 2024 letter, the following topics from two petitions will be reconsidered pursuant to CAA section 307(d)(7)(B): (1) work practice standards for unmeasured fugitive and intermittent particulate from unplanned bleeder valve openings; (2) the opacity limit for planned bleeder valve openings; (3) work practice standards for bell leaks; and (4) the opacity limit for slag processing and handling. In particular, the petitioners identified two errors in the final rule regulatory text related to the work practice standards for unplanned bleeder valve openings (issue 1) and identified ambiguity in the regulatory text for the work practice standards for bell leaks (issue 3). In the August 14, 2024 letter, the EPA initially identified these as items that could be corrected in a short-term corrections document; however, after further evaluation of the issues, the EPA concluded that making the changes necessary to address these items would require public notice and comment because the regulatory text containing the errors and ambiguity was introduced between the proposed rule and final rule and thus was not subject to public notice and comment as required by the CAA. Accordingly, in the March 5, 2025 letter, we found that the petitioners had demonstrated that it was impractical to raise their objections to these provisions during the period for public comment. We also found that their objections to the errors and ambiguity in the regulatory text for work practice standards for unplanned bleeder valve openings and bell leaks are of central relevance to the outcome of the rule. For bell leaks, we finalized language that was not proposed and directly impacts the ability for industry to comply with the standard. For unplanned bleeder valve openings, we inadvertently defined bleeder valve openings incorrectly that also directly impacts the ability for industry to comply with the standard as written. Additionally, industry petitioners provided new monitoring data to the EPA in their petitions for reconsideration. This monitoring, which was performed after the close of the comment period, demonstrates that it may be infeasible for some sources to comply with the final rule's opacity limits for planned bleeder valve openings (issue 2) and slag processing and handling (issue 4). This monitoring was performed to substantiate comments about operational variabilities industry had submitted during the public comment period that EPA did not have time to fully evaluate before promulgating the final rule. For this reason, industry was not aware of the need for these data until after the rule was published. Therefore, in support of their petitions for reconsideration, industry provided a more robust dataset than the information submitted pursuant to EPA's 2022 CAA section 114 information collection request during the development of the proposed rule; the new data were not collected as part of the CAA section 114 request and were not available to the EPA until after the rule was finalized. While the EPA concluded there are work practices available to minimize opacity, these new data provide evidence that there is more variability in each source's operations and opacity than we initially accounted for. Accordingly, in the March 5, 2025 letter, we found that the petitioners had demonstrated that it was impractical to raise these challenges to the feasibility of the proposed opacity standards during the public comment period. If we had received the additional data provided in the petitions during the public comment period, we may have structured the opacity limits in such a way as to account for additional variability. Based on this additional information provided by the petitioners after promulgation of the final rule and after further discussions and analyses, the EPA now understands that, in some cases, the equipment and work practices required by the final rule will not be sufficient or, in some cases, feasible to meet the standards as currently written, making petitioners' objections of central relevance to the outcome of the final rule. As part of the reconsideration proceeding looking at the issues identified in both the August 2024 and March 2025 EPA response letters, the EPA will prepare a notice of proposed rulemaking that will provide petitioners and the public an opportunity to comment on the issues identified for both discretionary and mandatory reconsideration. II. Stay of Certain Provisions By this action, the EPA is staying the effectiveness of certain aspects of the subpart revised by the final rule entitled, ``National Emission Standards for Hazardous Air Pollutants: Integrated Iron and Steel Manufacturing Facilities Technology Review,'' 89 FR 23294, for 90 days pursuant to its authority under section 307(d)(7)(B) of the CAA. Specifically, the EPA is staying the effectiveness of all provisions with April 3, 2025 compliance dates while the EPA addresses the reconsideration issues in a separate action. Therefore, pursuant to section 307(d)(7)(B) of the CAA, the EPA is staying the effectiveness of these compliance requirements for 90 days. This stay will remain in place until July 1, 2025, at which time those provisions will become effective.
