RCRA Hazardous Waste Generator Requirements are the EPA rules that govern any business that creates hazardous waste, from identifying the waste to storing it safely and shipping it to a permitted facility. They are issued under the Resource Conservation and Recovery Act (RCRA) and set out in 40 CFR Part 262. The rules protect workers, neighbors, groundwater and emergency responders from improperly stored or discarded chemicals.
Generators are responsible for their waste from the moment it is created until its final disposal, a principle often called cradle to grave. Auto shops, print shops, labs, hospitals, manufacturers and maintenance depots can all be generators, and their obligations depend on how much waste they produce each month.
What Are the RCRA Generator Requirements?
Part 262 is the federal rulebook for hazardous waste generators. Its core sections were reorganized by EPA's Hazardous Waste Generator Improvements Rule in 2016, which grouped the requirements by generator category:
- 262.11 requires a hazardous waste determination for every solid waste.
- 262.13 explains how to calculate your monthly generator category.
- 262.14 to 262.17 set the conditions very small, small and large quantity generators must meet to accumulate waste without a storage permit, including satellite accumulation in 262.15.
- 262.18 covers EPA identification numbers and re-notification.
- Subparts B and D cover manifests, recordkeeping and reporting, and Subpart M covers emergency preparedness for large quantity generators.
A waste is hazardous if it is listed by EPA in 40 CFR Part 261, Subpart D, or if it exhibits a characteristic of ignitability, corrosivity, reactivity or toxicity. Under 262.11, the determination must be made at the point of generation, before the waste is diluted or mixed, using knowledge of the process or testing when knowledge is not enough.
Who Must Comply?
Every person or business that generates a solid waste must determine whether it is hazardous. Your remaining obligations depend on your generator category, which 262.13 says you must determine each calendar month. EPA's generator categories page summarizes the federal thresholds:
- Very small quantity generator (VSQG): 100 kg (about 220 lb) or less of hazardous waste per month and 1 kg or less of acute hazardous waste.
- Small quantity generator (SQG): more than 100 kg but less than 1,000 kg per month, and 1 kg or less of acute hazardous waste.
- Large quantity generator (LQG): 1,000 kg (about 2,200 lb) or more per month, or more than 1 kg of acute hazardous waste.
Some wastes do not count toward the monthly total, including universal waste such as batteries and lamps managed under Part 273, used oil managed under Part 279, and waste managed during a planned or unplanned episodic event under Subpart L. Your category can change from month to month.
Most states run their own authorized RCRA programs, and many are stricter than the federal rules or use different category thresholds. Always confirm your state's requirements.
Key Requirements
Very small quantity generators
VSQGs must identify their hazardous waste, never accumulate more than 1,000 kg on site, and send waste only to a facility authorized to manage it, such as a permitted hazardous waste facility, a state-approved solid waste facility or a large quantity generator under the same company's control. Exceeding the on-site limits triggers SQG or LQG conditions under 262.14.
Small quantity generators
Under 262.16, SQGs may accumulate waste for up to 180 days, or 270 days if the receiving facility is 200 miles or more away, and may never hold more than 6,000 kg on site. Key conditions include:
- Containers in good condition, compatible with the waste and kept closed except when adding or removing waste.
- Weekly inspections of central accumulation areas for leaks and deterioration.
- Labels with the words "Hazardous Waste," an indication of the hazards and the accumulation start date.
- At least one emergency coordinator on site or on call at all times, with emergency information posted next to the telephone, and employees trained in proper handling and emergency procedures.
Large quantity generators
Under 262.17, LQGs may accumulate waste for no more than 90 days, with no limit on quantity. In addition to the container, inspection and labeling rules above, LQGs must keep containers of ignitable or reactive waste at least 50 feet from the property line unless the local fire authority approves otherwise in writing, and must follow formal closure procedures when an accumulation unit or the facility closes.
LQGs must also meet the preparedness rules in Subpart M. That includes a written contingency plan, a designated emergency coordinator and a quick reference guide for local emergency responders, required for generators that first became subject after May 30, 2017 and whenever the plan is amended. The guide summarizes waste types, quantities, site maps and emergency contacts.
Satellite accumulation areas
Section 262.15 lets any generator keep up to 55 gallons of non-acute hazardous waste, or one quart of liquid acute waste, at or near the point of generation under the control of the process operator. Containers must be closed and marked "Hazardous Waste" with the hazards. Once the limit is exceeded, the excess must be moved to central accumulation within three consecutive calendar days.
EPA ID numbers, manifests and e-Manifest
SQGs and LQGs need an EPA identification number, obtained with EPA Form 8700-12, before shipping waste. SQGs must re-notify every four years by September 1, a cycle that began in 2021, and LQGs must re-notify by March 1 of each even-numbered year. Shipments must travel on a hazardous waste manifest with a transporter that also holds an EPA ID number, and the waste must be packaged and labeled under DOT's hazardous materials regulations.
Since January 22, 2025, EPA requires SQGs and LQGs to register in the e-Manifest system with Site Manager or Certifier access so they can retrieve final signed manifests, and exception reports have been submitted through e-Manifest since December 1, 2025.
Training, Recordkeeping and Reporting
- LQG personnel training: Employees who handle hazardous waste must complete training within six months of hire or assignment, may not work unsupervised until trained, and must take part in an annual review. Training records are kept until closure for current employees and for three years for former employees.
- Waste determination records: SQGs and LQGs must keep records supporting each determination for at least three years from the date the waste was last sent for treatment, storage or disposal.
- Manifests: Keep each signed manifest for at least three years.
- Exception reports: An LQG that has not received a signed copy back from the receiving facility within 45 days must contact the transporter or facility, and must file an exception report at 60 days. SQGs report at 60 days.
- Biennial report: LQGs file a report by March 1 of each even-numbered year covering the prior odd-numbered year, and keep copies for three years.
Retention periods are automatically extended during any unresolved enforcement action.
Common Compliance Mistakes
- Open containers. Leaving funnels in drums is a common problem.
- Missing or incomplete labels. Labels need the words "Hazardous Waste," the hazards and, in central accumulation, the start date.
- Skipped weekly inspections. Inspections that are not documented are hard to prove.
- Miscounting monthly generation. A one-time cleanout can push a site into a higher category.
- Overfilled satellite areas. Waste beyond the limit must be moved within three days.
- Lapsed re-notification or e-Manifest access. Both are now routine inspection checks.
EPA and authorized states can assess civil penalties for each day of violation, adjusted annually for inflation, and serious knowing violations can lead to criminal charges.
How to Comply: Step by Step
- List every waste stream and make a documented hazardous waste determination for each.
- Calculate monthly generation and determine your category, then recheck it every month.
- Obtain or update your EPA ID number and set reminders for re-notification.
- Set up satellite and central accumulation areas with proper containers, labels and spacing.
- Run weekly inspections of central accumulation areas and log the results.
- Train employees on handling and emergency procedures, and document the training.
- Prepare emergency information: posted information for SQGs, or a contingency plan and quick reference guide for LQGs.
- Manage shipments through e-Manifest, track returned manifests and file reports on time.
How SMS360 Helps
Hazardous waste compliance depends on documents: waste determinations, manifests, inspection logs, contingency plans, training records and re-notification forms. SMS360's Document Library keeps these records organized, version-controlled and easy to retrieve when an inspector asks for them, while helping you manage retention periods.
Teams can pair the library with digital checklists for weekly accumulation area inspections, assign corrective actions when a label is missing or a container is open, and set reminders for biennial reports, re-notification and annual training reviews. Linking waste records to safety data sheets also helps support waste determinations.
Frequently Asked Questions
How do I know which hazardous waste generator category I am in?
Add up the hazardous waste you generate in a calendar month, excluding wastes such as universal waste and used oil. Under federal rules, 100 kg or less is a VSQG, more than 100 kg but less than 1,000 kg is an SQG, and 1,000 kg or more is an LQG. Generating more than 1 kg of acute hazardous waste in a month also makes you an LQG. Your state may use different thresholds.
How long can I store hazardous waste on site?
LQGs may accumulate waste for up to 90 days. SQGs may accumulate for up to 180 days, or 270 days if the waste must travel 200 miles or more, and may not exceed 6,000 kg on site. VSQGs have no federal time limit but may not exceed 1,000 kg on site.
Do small quantity generators need a contingency plan?
No. SQGs do not need a full written contingency plan, but they must have an emergency coordinator available at all times, post emergency information next to the telephone and make sure employees know handling and emergency procedures. LQGs must have a written contingency plan, and most also need a quick reference guide.
How long must hazardous waste manifests be kept?
Generators must keep each signed manifest for at least three years from the date the initial transporter accepted the waste. Biennial and exception reports must also be kept for three years, and the period is extended during any unresolved enforcement action.
