EPA finalized changes to its test procedures required to be used by industries and municipalities when analyzing the chemical, physical, and biological properties of wastewater and other samples for reporting under the NPDES permit program. 

United States v. Villegas, No. 1:24-cv-962 (D. Colo. Apr. 10, 2024). Under a proposed consent decree, settling CWA defendants that discharged pollutants without a permit into waters of the United States must restore impacted areas. 

United States v. Lexington-Fayette Urban County Government, No. 5:06-cv-386-KSF (E.D. Ky. Apr. 10, 2024). A proposed material modification to a consent decree concerning alleged violations of the CWA stemming from the settling defendant's operation of its sanitary sewer system and wastewater treatment plant extends the final compliance deadline for remedial projects by four years to December 31, 2030, and makes changes to reporting frequency and methods.
