Frequently Asked Questions
How hazardous waste generator numbers work and how to look them up.
What is a hazardous waste generator number?
A hazardous waste generator number (formally called an EPA Handler ID or RCRA ID) is a unique 12-character identifier assigned to every facility that generates hazardous waste under RCRA. The first two characters are the state abbreviation (e.g., TX, CA). This number must appear on hazardous waste manifests, biennial reports, and all regulatory submissions. If your facility generates hazardous waste and doesn't have one, you're required to obtain one before shipping waste off-site.
How do I find my hazardous waste generator number?
Enter your facility name or company name in the search above. Partial matches work fine, so you don't need the exact registered name. If you know your state, add a state filter to narrow results. Your generator number will appear as the "EPA Handler ID" in the results. If nothing comes up, your facility may not yet be registered with the EPA.
What is the difference between LQG, SQG, and VSQG?
These are the three RCRA hazardous waste generator categories, determined by how much hazardous waste your facility generates per month. Large Quantity Generators (LQG) generate 1,000 kg or more per month and face the strictest requirements. Small Quantity Generators (SQG) generate between 100–999 kg per month. Very Small Quantity Generators (VSQG) generate no more than 100 kg per month and have the fewest regulatory obligations. Your generator category determines accumulation time limits, storage requirements, and training obligations.
How do I get a hazardous waste generator number for a new facility?
Submit EPA Form 8700-12 (the RCRA Site Identification Form) to your state environmental agency. Many states now accept electronic submissions through RCRAInfo. You must notify the EPA before you begin generating hazardous waste, not after the fact. Once processed, your facility will be assigned an EPA Handler ID, which serves as your permanent generator number.
Can a generator's category change over time?
Yes. Generator status is determined monthly based on the quantity of hazardous waste generated. If your facility's output increases, you move up to a higher category and must comply with the stricter requirements immediately. If output decreases, you can re-notify to a lower category. The generator status shown in this tool reflects the most recent category reported to the EPA in RCRAInfo.
Why use this instead of RCRAInfo or EPA ECHO?
RCRAInfo and EPA ECHO are authoritative but not built for quick field lookups. Finding a generator's registration status in RCRAInfo typically means working through a more complex multi-step search form. This tool lets you search by name or address and surfaces generator category, active status, and compliance history in a single result. It also loads and responds well on mobile, which matters when you're verifying a vendor on-site.
Can I look up a vendor's or transporter's generator number?
Yes. This tool searches all RCRA-registered facilities nationwide, not just generators. You can look up treatment, storage, and disposal facilities (TSDFs) and transporters by name or ID. This is useful for verifying that a waste hauler or disposal vendor is properly registered before signing a manifest.
Know your generator number. Now stay compliant.
RCRAReady tracks accumulation deadlines, manifest returns, and generator status changes automatically. Your next EPA inspection won't catch you off guard.
