Comparison: State vs. Federal

Rules. Rhode Island has received primacy from the U.S. Environmental Protection Agency (EPA) to administer the underground injection control (UIC) program in the state for Class I, II, III, IV, and V wells. Unlike the federal rules, Rhode Island prohibits Class I, II, and III wells and allows Class IV wells only in accordance with RI Rule 12.190.015-10.1.2. Class V wells are permitted in the state if they comply with all state rules for the discharge of nonsanitary wastewater and other fluids to or below the ground surface. Permits for Class VI wells must be obtained from the EPA.

Administration and enforcement. DEM's Office of Water Resources administers the UIC Program in Rhode Island, and the Office of Compliance and Inspection enforces this disposal prohibition in Rhode Island. The EPA administers the UIC program for Class VI wells.
