California CUPA Guidance on Generator Improvements Rule 

Posted 06/21/24
To help hazardous waste generators in California achieve compliance with new and revised regulations from the Generator Improvements Rule, California DTSC and the Certified Unified Program Agencies (CUPA) plan to release guidance before July 1, 2024.

In June, state regulators announced plans to release two resources to assist the regulated community with compliance following substantial updates to the state’s hazardous waste regulations finalized in May 2024. 

CUPA Resources: Generator Improvements Rule

As announced in the Unified Program Newsletter, by July 1, CUPA will share a “comprehensive Frequently Asked Questions (FAQ) webpage” and a Quick Reference Guide (QRG) template for large quantity generators. Both resources will be posted to  DTSC’s Generator Improvements Rule webpage.

The template for a Quick Reference Guide (QRG)—a new mandatory element of the contingency plan for large quantity generators—will be available on the California Environmental Reporting System (CERS) website.

What's In the Generator Improvements Rule?

Areas of the California State hazardous waste management laws and regulations affected by the Generator Improvements Rule include: 

  • Generator site notifications to DTSC. 
  • Contingency planning and emergency preparedness.
  • Container markings/labels during accumulation and pre-transportation.
  • Updates for storing ignitable or reactive wastes at LQG sites.
  • Managing incompatible wastes in satellite areas. 

The Generator Improvements Rule also re-structures the hazardous waste management standards for generators in California to align them with re-arranged Federal RCRA regulations, moving the rules mainly to new sections of 22 CCR Part 66262.
