Changes to RCRA Hazardous Waste Generator Regulations

Posted on 7/6/2015 by Roger Marks

The United State Environmental Protection Agency (EPA) plans to propose changes to the RCRA hazardous waste generator regulations this month (July 2015). Named the Hazardous Waste Generator Improvements Rule, the forthcoming proposed rule “will suggest changes to the RCRA hazardous waste regulations to improve the effectiveness and clarity of the generator rules.”

What’s Planned for the New RCRA Generator Rules?

Provided as part of EPA’s Spring Regulatory Agenda printed in the Federal Register on June 18, the rule abstract lists a number of changes for generators, including:
  • Consolidating the hazardous waste generator regulations in part 262 of Title 40 of the Code of Federal Regulations (40 CFR);
  • Requiring additional information on hazardous waste container labels for large and small quantity generators; and
  • Setting streamlined rules that allow generators to maintain their “generator status” even when an episodic event causes them temporarily to move into a higher regulatory status.
Episodic Generation of RCRA Hazardous Waste

The last item on the list above addresses an issue that can cause some generators distress. Under the current RCRA regulations, a “large quantity generator”—a site that generates 1000 or more kg of hazardous waste per month—is subject to the most stringent management and storage standards.

Small quantity generators and conditionally exempt generators typically manage smaller quantities of waste, and therefore are subject to less-stringent management standards than their “large quantity” counterparts. However, a one-time event like a lab cleanout or an on-site spill can result in more than 1000 kg of waste generated in a particular month.

RCRA waste managers prepare for new rules from US EPA

When this happens, the site suddenly must comply with the more stringent Large Quantity Generator rules—including having a written contingency plan that includes arrangements with local emergency response authorities (police, fire, hospitals), a written training plan, and employee training records.

In other words, these one-time, “episodic” generator events can cause a site to fall out of compliance, without meaning to, and be responsible for meeting requirements they were never subject to as a small or conditionally exempt generator. A new rule would help environmental managers that may find themselves scrambling to comply when a one-time generation event pushes them over the limit for their current regulatory status.

EPA’s Hazardous Waste Generator Improvements Rule proposal has been under review by the Office of Management and Budget (OMB) since March of this year. The Rule Identification Number (RIN) for the rulemaking is 2050-AG70.
