Environmental Laws in Ohio.

Ohio environmental law combines federal programs (RCRA, CERCLA, CWA, CAA) with state implementation through the Ohio Environmental Protection Agency (Ohio EPA). Ohio has significant industrial-era contamination and Lake Erie water-quality issues (harmful algal blooms, Lake Erie Water Quality Monitoring). Ohio's Voluntary Action Program (VAP) provides liability relief for brownfield remediation. The 2014 Toledo water crisis (Lake Erie algal blooms) led to the Lake Erie Bill of Rights and related water-quality legislation.
