Environmental Protection Agency (EPA).
Notice of proposed consent decree; request for public comment.
In accordance with the Clean Air Act, as amended (CAA or the Act), notice is given of a proposed consent decree in Center for Biological Diversity et al. v. Lee Zeldin, No. 3:25-cv-6568-AMO. On August 5, 2025, Plaintiffs Center for Biological Diversity and Sierra Club filed a complaint in the United States District Court, Northern District of California, San Francisco Division. The EPA designated various areas of the country as nonattainment with respect to the 2010 SO 2 NAAQS. States that contain areas that are designated as nonattainment are required to provide State Implementation Plan submissions to the EPA within 18 months of the effective date of designations. The EPA is providing notice of this proposed consent decree, which would resolve all claims in the case by establishing deadlines for the EPA to take final action as specified in the decree.
Written comments on the proposed consent decree must be received by August 17, 2026.

If you submit an electronic comment, EPA recommends that you include your name, mailing address, and an email address or other contact information in the body of your comment.
