Welcome to RIDEM's Water Quality Certification (WQC) and Stormwater Construction (STW) online permit application search!
This page searches permitting activities administered by the State for WQC applications received after 1992 and for STW applications received after 2016. Permits are designed to meet the requirements of the Clean Water Act (CWA) and RI State Law to preserve, protect, and improve our water resources by preventing and minimizing stormwater runoff from washing harmful pollutants into waters of the State.
Enter search criteria below to view historical information or permit status for all applications. Approved plans and permit letters for most WQC and STW decisions issued after January 1, 2017 may also be available for download.
