12.4.2 MANAGING HAZARDOUS WASTE ON-SITE
LQGs are permitted to accumulate any quantity of waste in containers, tanks, and containment build-
ings for up to 90 days without a permit. Other forms of on-site storage (e.g., in a lined pond) usually
require a permit. Generators must mark the date when the accumulation begins on each hazardous
waste storage container so that it is visible for inspection. If the LQG facility accumulates wastes for
more than 90 days it is considered a TSDF and must follow regulations described in 40 CFR Parts 264
and 270. Designation of a hazardous waste generator as a TSD is undesirable for a generator, resulting
in a long list of new requirements and conditions along with increased costs for compliance.
In order to provide for more cost-effective shipments, SQGs can accumulate up to 6000 kg
(13,228 lb) of hazardous waste on-site for up to 180 days without a permit. The wastes can be accu-
mulated for up to 270 days if they must be transported more than 200 miles away for recovery,
treatment, or disposal. There are limited circumstances in which the state administrator may grant
extensions beyond 270 days. If the regulatory limits are exceeded, the generator is designated a
TSDF and must obtain an appropriate operating permit. Special storage requirements apply to
