Washington, D.C., Adopts Hazardous Waste Generator Improvements Rule


In 2016, The U.S. Environmental Protection Agency (EPA) updated its hazardous waste generator regulations to streamline interpretation of the rules and facilitate greater compliance. The Hazardous Waste Generator Improvements Rule (HWGIR) was published in the Federal Register on Nov. 28, 2016, and went into effect federally on May 30, 2017.

While most states have adopted the Hazardous Waste Generator Improvement Rule, some are still working toward putting the final rule into effect. Since the rule’s adoption timeline varies by state, it is essential for hazardous waste generators to remain informed about upcoming implementation dates. Clean Earth provides a monthly update on the process in each state to help businesses remain compliant.

Completed Rulemaking:

Washington, D.C.: Rulemaking is complete. The rule went into effect on January 20, 2023.

The amended rule is to go into effect in December 2023 if no hearing is required or June 2024 if a hearing is required. The existing rule remains in effect.
