## II. Additional Information About the Proposed Consent Decree

                    Plaintiffs filed a complaint in the United States District Court for the Northern District of California alleging that EPA failed to perform certain non-discretionary duties in accordance with the Clean Air Act under sections 110 and 179 to (i) determine that certain nonattainment areas under the 2010 primary SO2                     NAAQS had failed to submit required SIPs; (ii) promulgate                           ( print page 87369)                        FIPs for certain SO2                     nonattainment areas; and (iii) determine whether certain nonattainment areas had timely attained the NAAQS. Subsequently, EPA issued a notice determining that the areas alleged to have failed to submit SIPs in fact had so failed, thus mooting Plaintiffs' claim on those grounds.                

                    The EPA solicits public comments on a proposed consent decree that would establish deadlines for EPA to take proposed and final actions pursuant to CAA sections 110(c) and 179(c) related to the 2010 primary SO2                     NAAQS. The consent decree would require that EPA no later than December 19, 2024, sign a final notice (or notices) determining under CAA section 179(c) whether the Anne-Arundel/Baltimore County, MD; Alton Township, IL; St. Clair, MI; Freestone-Anderson, TX; Rusk-Panola. TX; Titus, TX; Evangeline Parish, LA; and Piti-Cabras, Guam, nonattainment areas timely attained the 2010 primary SO2                     NAAQS; and by August 29, 2025, sign a final notice under CAA section 179(c) determining whether the Huntington, IN nonattainment area timely attained the NAAQS and sign a final notice promulgating a FIP for that area under the NAAQS. The consent decree would also require that EPA no later than September 30, 2025, sign a proposed notice (or notices) to promulgate FIPs under the NAAQS for the Piti-Cabras, Guam and Evangeline Parish, LA nonattainment areas and by March 31, 2026, sign a final notice (or notices) promulgating FIPs under the NAAQS for the Piti-Cabras, Guam and Evangeline Parish, LA nonattainment areas; and by August 28, 2026, sign a final notice promulgating a FIP under the NAAQS for the Hayden, AZ nonattainment area. In addition, the consent decree would require that EPA no later than January 14, 2027, sign a proposed notice (or notices) to promulgate FIPs under the NAAQS for the Guayama-Salinas and San Juan, Puerto Rico nonattainment areas and by June 1, 2027, sign a final notice (or notices) promulgating FIPs under the NAAQS for the Guayama-Salinas and San Juan, Puerto Rico nonattainment areas; and by November 1, 2027, sign a final notice (or notices) determining whether the Guayama-Salinas and San Juan, Puerto Rico nonattainment areas timely attained the NAAQS.                

For a period of thirty (30) days following the date of publication of this notice, the Agency will accept written comments relating to the proposed consent decree. The EPA or the Department of Justice may withdraw or withhold consent to the proposed consent decree if the comments disclose facts or considerations that indicate that such consent is inappropriate, improper, inadequate, or inconsistent with the requirements of the Act.

The 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).

The electronic public docket system is an “anonymous access” system, which means EPA will not know your identity, email address, or other contact information unless you provide it in the body of your comment.                

Please ensure that your comments are submitted within the specified comment period. Comments received after the close of the comment period will be marked “late.” The EPA is not required to consider these late comments.
