🇬🇧 English

On March 30, 2026, the U.S. Department of Justice lodged a proposed material modification to a 2014 Consent Decree in the case United States and State of South Carolina v. the City of Columbia, South Carolina (Civil Action No. 3:13-cv-2429-TLW), filed in the U.S. District Court for the District of South Carolina. The original Consent Decree resolved alleged violations of the Clean Water Act related to Columbia's operation of its sanitary sewer system and wastewater treatment plant. The proposed modification requires the City of Columbia to complete four new infrastructure projects aimed at increasing sewer capacity, with a completion deadline of January 1, 2029. It also postpones the deadline for implementing the capacity assurance program—originally mandated by the 2014 Decree—in the specific subbasins where these new projects will occur, until after those projects are finished. A 30-day public comment period has been opened following publication of this notice. Comments may be submitted by email to pubcomment-ees.enrd@usdoj.gov or by mail to the Assistant Attorney General, U.S. DOJ–ENRD, P.O. Box 7611, Washington, DC 20044-7611. The proposed modification and original Consent Decree are publicly accessible at the Justice Department's consent decrees website.
