Comparison: State vs. Federal

Rules. Maryland has adopted the federal accumulation time rule that allows large quantity generators to accumulate hazardous waste for up to 90 days without a permit. However, in practice, Maryland's rule is more stringent than the federal because the state does not use the federal definitions of large quantity, small quantity, and conditionally exempt small quantity generators. In addition, the state allows accumulation for up to 180 days only under limited circumstances and, unlike the federal rules, does not allow accumulation for 270 days if the waste must be shipped more than 200 miles. For generator on-site hazardous waste storage requirements, see the state section HAZARDOUS WASTE STORAGE.

Check with MDE to see whether the state has yet adopted the federal accumulation time standards (adopted in March 2000) that allow hazardous waste large quantity generators (LQGs) who generate wastewater treatment sludges from the metal finishing industry (i.e., EPA Waste F006) to accumulate F006 beyond the usual 90-day LQG limitation.

Administration and enforcement. MDE's Land Management Administration administers and enforces the generator accumulation time requirements in Maryland.
