Frequent Questions

Section 265.174 of Subpart I requires that containers be inspected at least weekly for leaks and deterioration caused by corrosion or other factors. Both LQGs and SQGs must inspect containers in their central accumulation areas. Are SQGs or LQGs required

No. Inspections of containers (whether weekly or some other frequency) in SAAs are not required, so long as the provisions of 262.34(c) are met. Section 265.174, which requires inspections, is not among the provisions listed in 262.34(c) for SAAs (see Table 1). However, the SAA regulations do require that waste containers in an SAA must be under the control of the operator of the process generating the waste, in good condition (265.171), compatible with its contents (265.172), and closed except when adding or removing waste (265.173), which should achieve the goal of inspections: containers that are free of leaks and deterioration.

Note: On November 28, 2016, EPA published the Hazardous Waste Generator Improvements Final Rule, which makes several revisions to the hazardous waste generator regulations. These revisions may affect the information provided in this FAQ. The final rule and additional information, including a fact sheet, frequent questions, and a webinar recording and slides, are available at

The Hazardous Waste Generator Improvements Final Rule is effective on May 30, 2017; however, implementation in a particular state depends on the state’s authorization status. A discussion of the effect that this final rule will have on state authorization is available on page 85801 of the rule. Information about how the rule will affect the requirements in this FAQ in a particular state is best obtained from the state hazardous waste program. A list of state hazardous waste programs is available at
