The CESQG is exempt from most hazardous waste management requirements. A facility meet-
ing the test for a conditionally exempt generator (generating < 100 kg per month and < 1 kg of acute
hazardous waste) is out of the RCRA cradle-to-grave system, provided the waste is sent to a facil-
ity that is at least state-approved. Details of the major CESQG industries and waste types are listed
in Table 12.4.

12.3.5 EPISODIC GENERATORS
Depending on the type of business and the amount of hazardous waste generated monthly, a facil-
ity might be regulated under different rules at different times. If, for example, a metal plating firm
generates between 100 and 1000 kg (220 and 2200 lb) of hazardous waste during January, it would
be considered a SQG for that month and its waste would be subject to the hazardous waste man-
agement requirements for SQGs. If, in June, it generates more than 1000 kg (2200 lb) of hazardous
waste, its generator status would change, and it would be considered a LQG for June. Its waste for
that month would then be subject to the management requirements for LQGs. For such generators
it is to the firm’s advantage to maintain all records, management protocols for storage, transporta-
tion, and so on, as a LQG.

12.4 REQUIREMENTS FOR LQGS AND SQGS

Once the waste is determined to be hazardous and is counted, the LQG must comply with the full
spectrum of federal hazardous waste regulations under 40 CFR as well as 49 CFR (Department of
Transportation; see Chapter 13). The SQG is subject to less stringent requirements. The LQG and
SQG must notify the EPA and state regulatory agency of hazardous waste activity and obtain a U.S.
EPA ID number.

12.4.1 THE EPA IDENTIFICATION NUMBER
Identification numbers are required for facilities that generate or manage hazardous waste, includ-
ing LQGs and SQGs, transporters, and treatment, storage, and disposal facilities (TSDFs) (Chapter
14). Once the state regulatory authority is contacted, the generator will be sent EPA Form 8700-12,
Notification of Regulated Waste Activity (Figure 12.1). An EPA identification number will be sub-
sequently provided for each facility location.
