United States v. D.R. Horton, Inc., No. 2:24-cv-00428-AMM (N.D. Ala. Apr. 8, 2024). Under a proposed consent decree, settling CWA defendants that violated stormwater management requirements at 16 homebuilding construction sites must implement specified stormwater management practices, implement a supplemental environmental project that will cost $400,000, and pay a civil penalty of $400,000. 

EPA proposed to promulgate a CWA chronic aquatic life ambient water quality criterion for waters under the state of Idaho’s jurisdiction to protect aquatic life from exposure to harmful concentrations or levels of total mercury.
