Regulatory context

General reference. This is not an exhaustive review of applicable law.

United States: Clean Water Act / NPDES

NPDES regulates pollutant discharges from point sources to waters of the United States. The permit sets limits and monitoring conditions. A CWNS code identifies an inventory record, not an NPDES permit.

Permit identifier and permitting authority: EPA or an authorized state.
Outfall and receiving water; sewer connections follow a different control route.
Current permit conditions, limits and dated measurements; these are not included in CWNS.
