Comparison: State vs. Federal

Rules. New Hampshire has adopted the federal accumulation time rule that allows the largest class of generators to accumulate hazardous waste for up to 90 days without a permit, including the federal standards that allow certain generators of wastewater treatment sludges from the metal finishing industry (i.e., U.S. Environmental Protection Agency (EPA) Waste F006) to accumulate F006 beyond the usual 90-day limitation. However, New Hampshire's accumulation time rules are different from the federal rules, because the state does not use the federal definitions of large quantity generators (LQGs), small quantity generators (SQGs), and very small quantity generators (VSQGs). These different classifications plus New Hampshire's more stringent accumulation time requirements for the state's smallest class of generators result in accumulation time rules that are more stringent than the federal rules.
