State voluntary cleanup programs (VCP) Memorandums of Agreement (MOA) are agreements between EPA regional authorities and state environmental programs that promote the coordination and define general roles regarding the cleanup of sites. The agreement can further provide the public with the confidence that EPA and the state agency are working in a coordinated manner. Over time, the use of the MOA as a mechanism to strength EPA and state coordination at contaminated sites evolved.

Some MOAs and RCRA Memoranda of Understanding (MOUs) have included, among other things, a means to recognize the contribution VCPs or other state programs can make in addressing the cleanup and treatment storage and disposal (TSD) facilities and underground storage tanks regulated under the Resource Conservation and Recovery Act (RCRA) and PCB contaminated sites subject to remediation under the Toxic Substances Control Act (TSCA). In 2002, The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) was amended by the Brownfields Amendments that provides states and tribes that enter into MOAs with EPA are eligible for response program grants authorized by CERCLA Section 128(a)(1).
