Congressional Budget Office Cost Estimate: H.R. 524: A Bill to Amend the Federal Water Pollution Control Act to Clarify That the Administrator of the Environmental Protection Agency Does Not Have the Authority to Disapprove a Permit After It Has Been Issued by the Secretary of the Army Under Section 404 of Such Act [open pdf - 12KB]
"Section 404 of the Federal Water Pollution Control Act (Clean Water Act) established a program to regulate the discharge of dredged or fill material (for example, rock, sand, soil, clay, plastics, construction debris, wood chips, or waste from mining or other excavation activities) into waters of the United States, including wetlands. Proposed activities that could result in such discharges are regulated through a permit and review process wherein the U.S. Army Corps of Engineers (Corps) is responsible for making permitting decisions. Under current law, the Environmental Protection Agency (EPA) has the authority to revoke or modify permits issued by the Corps. Enacting this legislation would prohibit EPA from revoking a permit issued by the Corps under section 404 of the Clean Water Act."
