The regulations of the USEPA at 40 CFR 264 and 265 are applicable primarily to Treatment, Storage, and Disposal Facilities (TSDFs) that are required to operate under the conditions of a RCRA subpart C permit due to their handling of hazardous waste. Some of these regulations, however, are also applicable to generators of hazardous waste; such as 40 CFR 264/265, Subpart C Preparedness and Prevention to which both a Small Quantity Generator of hazardous waste and a Large Quantity Generator of hazardous waste are subject. Conversely, 40 CFR 264/265, Subpart D Contingency Plan and Emergency Procedures is not applicable to an SQG though it remains applicable to an LQG.

In these States compliance with the USEPA Federal rule ensures compliance with State regulations as well. Sometimes, however, a State can surprise you by throwing in some state-specific requirements after it has adopted the Federal rule. One example of this is in Missouri where the MO Department of Natural Resources operates the hazardous waste program. (more…)
