Clean Water Act data shown in ECHO come from the Permit Compliance System (PCS) or from the modernized system, ICIS-NPDES (Integrated Compliance Information System - National Pollutant Discharge Elimination System). ICIS-NPDES is gradually replacing PCS. The states/territories/tribes listed under the ICIS-NPDES search button below use ICIS-NPDES, and thus do not enter data into PCS. ECHO has separate query interfaces for PCS and ICIS-NPDES. To view data from a particular state, please choose the appropriate interface by clicking a search button below (states/territories/tribes using each system are displayed under each search button). For national or regional searches, you will need to do two separate queries - one with each interface. Alternatively, you may use the Multimedia interface if it includes the search options you need. The new ICIS-NPDES interface is similar to the long-standing PCS interface, but includes additional menu choices that are not available in PCS (for example, the new interface allows searching based on permit components).
