Comparison: State vs. Federal

Rules. Rhode Island follows the federal accumulation time rules that allow generators to accumulate hazardous waste on-site without a permit for specific periods of time. See the national section ACCUMULATION TIME to review the specific time periods applicable to each type of generator. Rhode Island, however, does not follow the federal provisions that allow, in certain situations, for up to 270 days for the on-site accumulation of hazardous waste.

Generators should note that Rhode Island requires generators to comply with on-site storage standards that are in addition to those required under federal law. See the state section HAZARDOUS WASTE STORAGE for guidance on how to store hazardous waste on-site without a permit in compliance with the state's more stringent requirements.

Administration and enforcement. The Rhode Island Department of Environmental Management's (DEM) Office of Waste Management administers and enforces the generator accumulation time requirements in Rhode Island.
