Frequent Questions

What regulations apply to generators of hazardous waste managed at satellite accumulation areas?

The satellite accumulation provisions allow for reduced requirements for hazardous waste accumulated in containers at or near any point of generation (§262.34(c)).  A generator may accumulate up to fifty-five gallons of hazardous waste or one quart of acutely hazardous waste at each satellite accumulation area if it is under the control of the person operating the process that generates the waste (§262.34(c)).  Limited standards, such as labeling, keeping the containers closed and maintaining containers in good condition, apply to satellite areas (§262.34(c)(1)(i) and (ii)).  Once the generator exceeds the volume limits, the excess waste must be dated and moved within three days to the central accumulation area. At the central accumulation area, the waste must be managed in accordance with the fuller hazardous waste accumulation standards in §262.34.

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
