 also continue to focus on methane emissions reductions by improving its natural gas distribution systems, and has set a target across its natural gas distribution operations, including our operations, to achieve net-zero methane emissions by the end of 2030. WEC Energy Group plans to achieve its net-zero goal through an effort that includes continuous operational improvements and equipment upgrades, as well as the use of RNG throughout its natural gas utility distribution systems. In addition, subject to regulatory approval and market conditions, WEC Energy Group expects to procure RTCs.Water QualityClean Water Act Cooling Water Intake Structure RuleRevisions to an EPA rule authorized under Section 316(b) of the CWA became effective in October 2014 and requires the location, design, construction, and capacity of cooling water intake structures at existing power plants reflect the BTA for minimizing adverse environmental impacts. The rule applies to all of our existing generating facilities with cooling water intake structures, except for the ERGS units, which were permitted and received a final BTA determination under the rules governing new facilities. Effective in June 2020, the requirements of Section 316(b) were incorporated into the Wisconsin Administrative Code. The WDNR applies this rule when establishing BTA requirements for cooling water intake structures at existing facilities. These BTA requirements are incorporated into WPDES permits for our facilities. We have received interim BTA determinations for all generation facilities where Section 316(b) is applicable. With respect to OCPP Units 7 and 8, we believe that in accordance with the requirements in the CWA, the WDNR will determine that existing technology (wet cooling towers) installed at the units represents BTA for minimizing adverse environmental impacts when the WPDES permit for those units is reissued, which is expected later in 2025.

Steam Electric Effluent Limitation GuidelinesThe EPA's 2015 final ELG rule, which took effect in January 2016 (2015 ELG rule), was modified in 2020 (2020 ELG rule), and again in May 2024 with the publication of the Supplemental ELG Rule. These rules establish federal technology-based requirements for several types of power plant wastewaters. The three requirements that affect us relate to wastewater discharge limits for BATW, FGD wastewater, and CRL (landfill leachate). Although our coal-fueled facilities were constructed with advanced wastewater treatment technologies that meet many of the discharge limits established by the
