The Permit Compliance System (PCS) and Integrated Compliance Information System (ICIS) provides information on companies which have been issued permits to discharge waste water into rivers. You can review information on when a permit was issued and expires, how much the company is permitted to discharge, and the actual monitoring data showing what the company has discharged. Many states have migrated to the new NPDES database, so the data for those states is static in EnviroFacts for those states. See the Full Search for a list of states. More information on PCS/ICIS.
