California Environmental Report System (CERS)

Beginning January 1, 2013 State law requires that all CUPA-regulated businesses submit hazardous materials business plan (HMBP) and underground storage tank (UST) information electronically through the California Environmental Reporting System (CERS). For assistance with how to use CERS please visit the CERS Help Center or contact your inspector.

Siskiyou County businesses must annually certify or update their HMBP by March 1 of each year.
