Compliance and Enforcement Permit Compliance System

Data Systems

Permit Compliance System (PCS) is a national computerized management information system that

PCS was developed in 1974 and resides on a mainframe computer at EPA's National Computer Center (NCC) at Research Triangle Park (RTP) in North Carolina. PCS records water-discharge permit data on more than 150,000 facilities nationwide.

For the past several years PCS has been undergoing a modernization effort to address outdated technology and new program requirements. As of June 16, 2009, 31 states, territories and tribes are using ICIS-NPDES. The remaining 22 NPDES states will move from PCS to ICIS (Integrated Compliance Information System) over the next few years.
