As a regulated business, your facility is required to review and submit information regarding the Hazardous Materials Business Plan, Hazardous Waste Generator, Underground Storage Tanks, Aboveground Petroleum Storage Act, and/or California Accidental Release Prevention Programs annually (CUPA data). State Law requires your business to report this information electronically.

Contra Costa Health Services Hazardous Materials Programs (CCHSHMP) requires the annual CUPA data to be submitted through the California Environmental Reporting System (CERS) between January 1, 2023 and March 1, 2023.

Note to Hazardous Waste Generators:

If your hazardous waste disposal calculations fall within the same range you reported for the 2023 annual submittal, you do not need to submit the HWG Reporting form. Calculations will be verified during your next inspection. Discrepancies confirmed during an inspection will result in a fee adjustment.
