Environmental Laws in Missouri.
Missouri environmental law combines federal programs (RCRA, CERCLA, CWA, CAA) with state implementation through the Missouri Department of Natural Resources (DNR). Missouri has adopted the Hazardous Waste Management Law and Missouri Clean Water Law, which implement delegated RCRA and CWA authority. Missouri hosts significant legacy contamination including Superfund sites in St. Louis (radioactive waste) and around lead-mining regions in southeast Missouri. The Missouri Brownfield/Voluntary Cleanup Program provides liability relief for approved remediation.
