Clean Water Act: Proposed Revisions to EPA Regulations to Clean Up Polluted Waters

Pursuant to a congressional request, GAO reviewed the economic and compliance issues associated with two proposed Environmental Protection Agency (EPA) regulations to clean up polluted waters, focusing on: (1) the reasonableness of EPA's economic analyses for the two proposed regulations; and (2) whether EPA's determinations under the Unfunded Mandated Reform Act of 1995 and the Regulatory Flexibility Act were adequately supported.
