How Small Quantity Generators of Hazardous Waste Can Store Hazardous Waste for up to 270 Days [40 CFR 262.34(e)]
Environmental
Small Quantity Generators of hazardous waste (SQGs) are classified as facilities that generate between 100-1000 kg of hazardous waste in a calendar month. Normally, SQGs can accumulate hazardous waste for up to 180 days at central accumulation areas (40 CFR 262.34(d)). SQGs also cannot store more than 6000 kg at any one time (40 CFR 262.34(d)(1)).
There is an exception to the 180-day accumulation provision at 40 CFR 262.34(e). If the waste will be transported for more than 200 miles for off-site treatment, storage, or disposal, SQGs may accumulate hazardous waste onsite for 270 days. EPA has clarified that a SQG may accumulate waste for up to 270 days if they ship to a treatment, storage, or disposal facility (TSDF) greater than 200 miles away, even if there is an alternate TSDF closer than 200 miles (EPA Monthly Call Center Report Question, August 1987, RCRA Online 13000).
The extension of the storage duration from 180 to 270 days does not change the 6000 kg onsite accumulation limit.
