California Environmental Reporting System (CERS) Instructions


All regulated businesses are required to review and submit information regarding the annual Hazardous Materials Business Plan, Hazardous Waste Generator Reporting, Underground Storage Tanks, Aboveground Storage Tanks, and/or California Accidental Release Prevention Program annually (CUPA data). State law (Assembly Bill 2286) now requires your business to report this information electronically. Contra Costa County requires all facilities to use the California Environmental Reporting System (CERS) to submit this information: cers.calepa.ca.gov. All regulated businesses must use CERS to submit their 2015 CUPA data between January 1, 2015 and March 2, 2015.

All 2015 CUPA data must be submitted by March 2, 2015.
