as established under the CWA. Dischargers must apply for and obtain a site-specific NPDES permit (or State equivalent) or a
general NPDES permit.
Also, the EPA, as its mandate, must publish and update ambient surface-water-quality criteria under the CWA. These
criteria are not legally enforceable; however, many states require that the levels as set forth in these criteria be met in surface
waters. The ambient criteria refer to pollutant concentrations found in the receiving water and not solely the discharge.
Regulatory Information in Foreign Countries: Foreign countries will have their own guidance on disposal of wastes as
well as ambient water quality criteria. Usually the Final Governing Standards, derived from the DOD Overseas Baseline
Guidance Document and the host nation standards, contain these requirements. Coordination should be made with the
installation facility engineer to determine the requirements for discharge.
