About RCRA Site Identification Numbers

Persons who generate, transport, treat, store or dispose of hazardous waste and who store recyclable materials prior to recycling them must determine if they are required under the Resource Conservation and Recovery Act (RCRA) to notify EPA of their hazardous waste activities and obtain an EPA RCRA Site Identification number.

Very small quantity generators and persons whose solid waste has been excluded from regulation or whose hazardous waste has been exempted may not need to notify unless the authorized state requires notification.

A RCRA Site ID number is assigned by EPA to the address of the physical location for each generator, transporter, and treatment, storage or disposal facility and should be used on documents and forms subsequently submitted to EPA and states.

Visit the RCRAInfo website to confirm whether a location has an existing RCRA Site ID number.

RCRAInfo Web is the public version of the RCRA Database and is updated weekly.

Requests for Extensions on Hazardous Waste Accumulation

An extension request for hazardous waste accumulation may be granted for a generator that cannot meet hazardous waste accumulation time limit requirements due to unforeseen, temporary and uncontrollable circumstances, per 40 CFR 262.16(d) and 262.17(b).

If the request is approved, an extension of up to 30 days may be granted on a case-by-case basis

For sites in Alaska and on Tribal lands, please submit your hazardous waste accumulation extension request electronically to AlaskaRCRA@epa.gov with "Accumulation Extension Request" and the facility's EPA ID number included in the subject line.

The request must be received prior to the expiration of the original accumulation time limit, and must include EPA ID number, generator point of contact information, generator category, descriptions of the waste, and reasons for the request.
