Hazardous Waste Generator Requirements Explained

I’ve had conversations where someone asks, “Do we really need an EPA identification number just for a few drums of waste?” Or, “Wait, what’s our hazardous waste generator status again?” These things tend to come up when paperwork’s due or someone’s prepping for a shipment, and honestly, the confusion makes sense. The hazardous waste generator requirements are layered, and the language doesn’t always make it easy to know what applies to you.

A colleague once shared that they didn’t realize they’d quietly crossed into large quantity generator range until they were already a few weeks past the threshold. Nothing dramatic—just a few extra projects that pushed their volume over. That small bump meant scrambling to get staff trained, relabel containers, and adjust their accumulation timeframes. All of that kicked in just because their RCRA generator status had changed.

That’s the thing: even small changes can mean big differences in what you're required to do. And if you're not watching for it, it can catch you off guard. So I put this together to walk through the basics: what the categories mean, what you actually need to track, and how to stay in step with the rules without it turning into a full-time job.

Key Takeaways

• A facility’s hazardous waste generator status is determined by the total volume of hazardous waste produced in a calendar month, and it dictates the applicable hazardous waste generator requirements.
• Exceeding generator thresholds, even temporarily, can trigger more stringent large quantity generator requirements, unless the event qualifies under EPA’s episodic generation provisions.
• Waste profiles are required for each unique hazardous waste stream and must be developed using either generator knowledge or analytical testing, depending on the consistency and documentation of the waste.
• Maintaining an accurate EPA identification number, staying within accumulation time limits, and following training and reporting rules are all part of cradle-to-grave compliance under the facility’s assigned RCRA generator status.

Determining Your RCRA Generator Status

What Is a Hazardous Waste Generator?

A hazardous waste generator is any site or operation that produces waste the EPA classifies as hazardous under the Resource Conservation and Recovery Act (RCRA). That includes everything from solvent-soaked rags to spent chemicals and certain sludges. Basically, anything that shows up on the EPA’s hazardous waste lists or meets one of the characteristic definitions, like ignitable or reactive wastes.

I’ve talked with folks who assumed the term only applied to chemical manufacturers or refineries, but I’ve seen very small quantity generators pop up in places you’d never expect, like dentist offices, print shops, even high schools with lab cleanouts. If your facility produces hazardous waste, regardless of the type of work you do, then you fall under the umbrella of generators of hazardous waste.

What Determines RCRA Generator Status?

Your RCRA generator status comes down to how much hazardous waste your site produces in a calendar month—that’s what 40 CFR § 262.13 lays out. The EPA separates generators into three categories based on volume: very small quantity generator, small quantity generator, and large quantity generator.

Here’s how the breakdown looks:

It’s easy to look at these numbers and think you’re nowhere near them, but in reality, a month’s worth of waste adds up faster than most people expect. The image below shows just a few labeled containers set aside for shipment—nothing excessive, but already part of a facility’s monthly total. If you’re not tracking consistently, those routine accumulations can shift your status before anyone realizes. That’s why it helps to tie what’s in your logs to what’s physically on site.

How to Determine Hazardous Waste Generator Status

Once you know the categories, the next step is keeping track of what your site generates each month. That’s what defines your status, and that’s what you’ll be held to if anyone checks.

What’s worked best for me is keeping it simple but consistent. Here’s how I usually approach it:

Track Monthly Waste Totals

• Log how much hazardous waste is generated at each source across your facility. This includes process waste, cleanup activities, and satellite accumulation areas.
• Use weight (kg or lbs) per calendar month. Keep the records consistent and easy to refer back to.

List All Hazardous Waste Streams

• Include anything that meets the EPA’s criteria, and don’t just track the obvious stuff. If it’s listed, characteristic, or acutely hazardous waste, it counts.
• Match each stream with the right waste code and Safety Data Sheets (SDS), especially if you’re later asked for documentation or need to submit a waste profile.

Account for Short-Term Spikes

• A temporary jump in waste, like during maintenance shutdowns or cleanouts, can affect your status.
• If your state follows the episodic generation rules, you may be able to stay in your usual category, but it requires the right documentation and timing.

Once your tracking system is in place, stay consistent with it. You don’t need complex software, but you do need clear records in case your hazardous waste generator status is ever questioned or changes month to month.

Why Status Matters

I’ve always said that your hazardous waste generator status sets the ground rules. Once you're in a category, the requirements aren't optional. They come with deadlines, paperwork, training, and storage limits that you’re expected to follow.

Why does it matter? Because the EPA uses your RCRA generator status to decide how closely you’re regulated. The higher your status, the more is expected—more documentation, more employee training, stricter storage timelines, and more reporting. It changes how you handle hazardous waste from the moment it’s generated to when it leaves your site.

Here’s a breakdown of what changes as your status increases:

Getting an EPA Identification Number

What Is an EPA Number?

An EPA identification number is basically your facility’s tracking ID in the hazardous waste system. It’s how the EPA, and your state (if they run their own program), know who you are, what kind of waste you’re generating, and where that waste is going.

I like to think of it as your hazardous waste mailing address. When you send waste off-site for treatment, storage, or disposal, your EPA identification number is what links that shipment back to you. It shows up on manifests, reports, and most compliance paperwork you’ll deal with.

The number itself is site-specific, so if your company operates at multiple locations, each one that generates hazardous waste needs its own. It’s also permanent unless you move, stop generating waste, or your site changes ownership. That’s why keeping it up to date is part of staying in good standing.

Who Needs One?

If you're a large quantity generator or a small quantity generator, you need an EPA identification number—no way around that. For very small quantity generators, it gets a little less clear. Federal rules don’t require one, but a lot of states do. I’ve heard of facilities that assume they were too small to need an ID, only to run into trouble when a shipment was delayed or turned away because their state had tighter rules.

• Large Quantity Generator (LQG): Required under federal law
• Small Quantity Generator (SQG): Also required federally
• Very Small Quantity Generator (VSQG): Not required federally (but your state might still expect you to have one—some do, some don’t)

If your state is authorized to run its own hazardous waste program under 40 CFR § 271.10, it can tighten things up beyond the federal minimum. That’s why it’s always smart to double-check with your state environmental agency, even if you think you’re in the clear.

And honestly, even if you're a VSQG in a state that doesn’t require it, having an EPA identification number on file can save time later, especially if your status changes or you need to move waste through someone else’s system.

How to Obtain It

Step 1: Figure out if you’re applying through the EPA or your state

Some states handle ID numbers themselves, while others go through the EPA’s system. If you’re not sure, check your state environmental agency’s website.

Step 2: Gather your site information

You’ll need the legal site name, physical location, mailing address, and contact information. Make sure everything matches how your facility is registered with other agencies.

Step 3: Fill out EPA Form 8700-12

This is the form used to apply for, update, or deactivate an ID number. It asks for your generator status, waste activities, and site details. If you’re using the EPA’s system, you’ll likely be doing this through RCRAInfo (their online portal). Some states have their own system that looks different but collects the same information.

Step 4: Submit through the correct system

If your state uses RCRAInfo, you can submit it online. If not, they’ll usually have a form upload or email option. Some still take hard copies, depending on how updated their process is.

Step 5: Wait for confirmation

Once it’s processed, you’ll get your EPA identification number, usually a 12-character ID that starts with your state abbreviation. It shows up on all future paperwork tied to hazardous waste shipments from that site.

The first time I walked someone through this, they had no idea that even a small mistake, like mismatching a site name or skipping a checkbox, could kick the form back. Taking ten minutes to double-check everything upfront saved them a week of delay.

Once you’ve got your number, hold onto it. You’ll be using it every time you send out waste, update your generator status, or fill out any kind of reporting tied to your hazardous waste activity.

When to Update or Deactivate

Once you’ve got your EPA identification number, it sticks with your site, but it’s not a “set it and forget it” thing. You’re expected to update it when key details change. Here’s when you’ll need to update or deactivate your number:

• Your generator status changes: If you move from a small quantity generator to a large quantity generator, or drop down to a very small quantity generator, you need to update the form to reflect that.
• You move to a new location: The number is tied to the site, not the company. If your operations move, you’ll need to apply for a new number and deactivate the old one.
• The site changes ownership: If the business is sold or transferred, the new owner needs to submit a new form under their name. The old number should be closed out.
• You stop generating hazardous waste altogether: If you shut down or no longer generate regulated waste, you should deactivate your number to avoid being listed as active when you’re not shipping anything out.
• You’ve made an error on the original submission: Even small mistakes—like a wrong NAICS code or incorrect contact info—should be corrected by submitting an updated form.

You can make changes using the same EPA Form 8700-12, either online through RCRAInfo or whatever process your state uses. Keeping this current helps avoid delays during shipments and keeps you off the radar for avoidable violations.

I always tell people: if something’s changed, assume your EPA records need to change too. It’s easier to fix it now than explain it later.

Creating and Managing Waste Profile

What Is a Waste Profile?

A waste profile is a formal record that describes the properties of a hazardous waste stream. It provides treatment, storage, and disposal facilities (TSDFs) with the information they need to accept, manage, and process waste properly. Each individual waste stream generated at a site must be profiled separately, even if the end destination is the same.

The format and submission process vary depending on the TSDF, but the purpose is the same: to communicate the nature of the waste clearly, including how it was generated and what characteristics apply under federal or state hazardous waste regulations.

Waste profiles are typically created before the first shipment of a new waste stream and updated when there’s a change in composition, process, or classification. While they aren’t submitted to the EPA, they’re part of a generator’s obligation under the broader framework of hazardous waste generator requirements.

A typical profile includes things like:

• Waste codes and classification
• Physical appearance (solid, liquid, sludge, etc.)
• Flash point, pH, and other test data
• Generator knowledge or lab analysis used to identify it
• Safety Data Sheets (SDS), if applicable
• EPA ID and contact information
• Container and shipping info

Why It’s Required

The waste profile is required because TSDFs cannot accept hazardous waste without documented information about what the material is and how it should be handled. It’s not optional but part of the operating conditions for receiving facilities and a core part of the generator’s compliance responsibilities.

Under the cradle-to-grave system, the generator retains legal responsibility for hazardous waste until it is properly treated or disposed of. That responsibility includes providing accurate documentation. If a waste stream is mischaracterized or missing a profile, it can delay acceptance, cause a shipment to be rejected, or trigger violations for both the generator and the TSDF.

For facilities operating under large quantity generator requirements, any delay tied to inaccurate or missing waste profiles can affect storage timelines and manifest schedules. The requirement is there to prevent mismanagement and ensure every shipment is traceable, classifiable, and legally handled from pickup to final treatment.

How to Develop a Waste Profile

There are two main ways to characterize a hazardous waste stream: through generator knowledge or by conducting analytical testing. The method used depends on how consistent the waste is and how well the generator understands the process that creates it.

Each profile should be developed for a single waste stream. If your site generates multiple waste types from different operations, each one needs its own documentation. This becomes especially important for facilities subject to large quantity generator requirements, where profiles need to stay aligned with accumulation practices and manifest documentation.

What I usually focus on is whether the supporting information clearly reflects how the waste is generated and handled. If something doesn’t match the profile (like a flash point that’s off or a missing waste code), it can hold up a shipment or trigger a rejection at the TSDF.

The specific fields required in a waste profile usually depend on the TSDF you're working with, but the information needs to line up with how the waste is actually generated and classified. Accuracy here ties directly into your broader hazardous waste generator requirements, especially if you're operating under large quantity generator requirements and timelines are tight.

What Happens If You Temporarily Exceed Your Generator Limits?

Not every spike in hazardous waste generation changes your facility’s long-term category. Under RCRA generator status rules, the EPA recognizes that waste volumes can fluctuate. That’s where the option for episodic generation becomes relevant—a provision that lets you temporarily generate more hazardous waste than usual without permanently moving into a higher status.

This applies to both planned and unplanned events:

• A planned episode might be a tank cleanout or a large disposal project.
• An unplanned one could be a spill response or damaged inventory that needs disposal.

Either way, if managed correctly, you can stay within your usual hazardous waste generator status and avoid taking on additional obligations under large quantity generator requirements.

But there’s a catch: not every state has adopted these rules. Episodic generation is outlined in 40 CFR Part 262 Subpart L, but states running their own programs may not recognize it. That means before relying on the rule, you’ll need to confirm whether your state allows it.

If your state does recognize episodic generation, here’s what typically needs to happen:

• Notification is required. Either 30 days in advance for planned events or within 72 hours for unplanned ones.
• The waste must be shipped off-site within 60 days of the start of the event.
• You must keep records of the event, including dates, volumes, and documentation of proper shipment and disposal.

Even one improperly managed episode can shift your hazardous waste generator requirements for the month, pushing you into a higher tier with more regulatory expectations. That includes changes to manifesting, training, reporting, and time limits under large quantity generator requirements.

I always recommend treating episodic events like their own small project. If it’s not documented properly or the waste sits too long, your RCRA generator status could change—whether you planned for it or not.

FAQs

How much hazardous waste per month can a small quantity generator generate?

A small quantity generator can generate more than 100 kilograms (≈220 pounds) but less than 1,000 kilograms (≈2,200 pounds) of hazardous waste per calendar month. They must also generate no more than 1 kilogram of acute hazardous waste and no more than 100 kilograms of residue or contaminated materials from the cleanup of acute hazardous waste.

Can a facility operate under two different generator statuses at once?

No. A site is assigned a single hazardous waste generator status based on the total quantity of hazardous waste generated in a given calendar month. If different processes or areas generate varying amounts of hazardous waste, the total is still combined to determine the facility's overall RCRA generator status for that month.

Is hazardous waste generator status affected by satellite accumulation areas?

Yes, but indirectly. Waste stored in satellite accumulation areas counts toward the facility's total monthly generation once it's moved to a central accumulation area or when the container is filled. Once a satellite accumulation area exceeds 55 gallons, the excess must be moved to the central storage area within 72 hours. So while satellite areas help manage collection at the point of generation, they don't change your overall hazardous waste generator status.

What is the maximum amount of waste that can be stored on site for a large quantity generator?

There is no maximum volume limit for a large quantity generator, but they must follow strict time-based rules. Under large quantity generator requirements, hazardous waste can only be stored on site for up to 90 days without a permit. The focus is on time, not volume.

How often is RCRA training required for a large quantity generator?

Under large quantity generator requirements, RCRA training must be provided initially when an employee begins hazardous waste management duties, with periodic refresher training thereafter. The federal regulations don't specify an annual requirement, but many facilities implement annual refresher training as a best practice. The training must be job-specific and documented, and new personnel handling hazardous waste must be trained before they handle hazardous waste independently.
