CWA/CERCLA Site Specific Sample Memorandum of Understanding

The sample memorandum of understanding (MOU) was created to provide a template to facilitate collaboration among EPA, states, and federally-recognized Indian tribes, as well as other federal agencies. Given that roles and responsibilities under the Clean Water Act (CWA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) often are shared by these different entities, the close collaboration can be crucial when addressing contaminated sediments and their associated waters. Issued 11/21/2017

The sample MOU, included with the transmittal memorandum, is available for download in Word format from the Cleanup Enforcement Model Language and Sample Documents Database under the Memorandum of Understanding category.

The transmittal package, containing the memorandum and the sample MOU as issued, are available in the link below.
