SUPPLEMENTARY INFORMATION:

I. Additional Information About the Proposed Consent Decree

Under the CWA, WQS define the desired condition of a water, in part, by designating the use or uses of the water and by setting criteria to protect those uses.^[1] Human health criteria (HHC) are ( printed page 46433) a type of water quality criteria that protect designated uses such as public water supply and recreation.

While states have the primary responsibility for reviewing, establishing, and revising WQS for their waters, CWA section 303(c) directs the EPA to promulgate WQS in two circumstances. Of relevance here, the EPA has the authority to promulgate WQS where the EPA Administrator determines that a new or revised standard is necessary to meet the requirements of the CWA.^[2] Such a determination is referred to as an “Administrator's Determination.” Once the EPA makes an Administrator's Determination, the CWA requires the Agency to “promptly prepare and publish” proposed regulations with new or revised WQS.^[3] The CWA also requires that the Administrator “promulgate any revised or new standard [ . . . ] not later than ninety days after [publishing] such proposed standards.” ^[4]

CWA section 303(c)(2)(B), added to the CWA in the 1987 amendments to the Act,^[5] requires states to adopt numeric criteria for all toxic pollutants listed pursuant to CWA section 307(a)(1) (known as priority toxic pollutants ^[6] ) for which the EPA has published recommended criteria pursuant to CWA section 304(a), and where the discharge or presence of such toxic pollutants could reasonably be expected to interfere with the states' designated uses.^[7] In the 1992 National Toxics Rule, the EPA promulgated water quality criteria for priority toxic pollutants for 14 states, including Florida, based on an Administrator's Determination that the states needed new or revised criteria to comply with the requirements of CWA section 303(c)(2)(B).^[8]

On December 1, 2022, the EPA issued an Administrator's Determination that Florida needed new and revised HHC pursuant to CWA section 303(c)(4)(B).^[9] Specifically, the Agency determined that Florida's existing HHC were not protective of Floridians consuming fish and shellfish because the EPA believed they were derived using data that underestimates how much fish Floridians are currently eating. The EPA also determined that Florida needed HHC for 37 additional priority toxic pollutants for which the State had no HHC. The EPA proposed new and revised HHC for Florida on December 8, 2023.^[10] No final action was taken on the proposed rulemaking.

On August 19, 2025, the Environmental Defense Alliance and Waterkeepers Florida (Plaintiffs) filed a complaint in the U.S. District Court for the Middle District of Florida, alleging that EPA failed to perform a mandatory duty to promulgate final WQS for Florida waters 90 days after proposing such standards. The complaint asserts that this failure violates both the CWA and the APA.

The parties initiated settlement discussions, which produced the proposed consent decree. Under the proposed consent decree, the EPA Administrator would be required to sign a final rule establishing new and revised HHC for Florida waters on or before December 1, 2026.

For a period of thirty (30) days following the date of publication of this Federal Register publication, EPA will accept written comments relating to the proposed consent decree from persons who are not parties to the litigation. EPA or the Department of Justice may withdraw or withhold consent to the proposed consent decree if the comments received disclose facts or considerations that indicate that such consent is inappropriate, improper, inadequate, or inconsistent with the requirements of the CWA.
