Environmental Health Division - Hazardous Materials Management (CUPA)

The Hazardous Materials Management Group implements the Unified Program (UP), at the local government level pursuant to Title 27 § 15110(a)(2). Siskiyou County Environmental Health Division of the Community Development Department became the Certified Unified Program Agency (CUPA) on January 1, 1997. The Environmental Health Division is certified by the Cal/EPA Secretary to implement the Unified Program specified by Health and Safety Code § 25404(a)(1)(A), within Siskiyou County.

Senate Bill 1082 (Chapter 418, Statutes of 1993) created the Unified Program (UP) to consolidate, coordinate, and make consistent the administrative requirements, permits, inspections and enforcement activities, and fees for the program elements detailed below.

With a State of California Registered Environmental Health Specialist (REHS) on call 24 hours a day, Siskiyou County Environmental Health is responsible for responding to incidents involving any release or threatened release of hazardous materials. Threats to people, property and the environmental are assessed, and then remedial action procedures are conducted under the supervision of an REHS.

Environmental Health Hazardous Material Programs

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 business must annually certify or update their HMBP by March 1 of each year.

The purpose of the business plan program is to prevent damage to the heatlh and safety of workers, the public, and the environment from the release or threatened release of hazardous materials. In addition, the business program is used to satisfy Community Right-To-Know laws by providing hazardous material information to emergency responders and the community.

Businesses located in cities and unincorporated areas of Siskiyou County are required to disclose all hazardous material and waste that are used, handled or stored at their facility above reporting thresholds. In general, the reporting thresholds are:

  • 55 gallons for liquids
  • 500 pounds for solids
  • 200 cubic feet for compressed gases

Business plan information must be electronically submitted through the California Electronic Reporting System (CERS). Business plans must be annually certified or updated by March 1 of each year, or within 30 days of a substantial change. Annual facility inspections are conducted to verify the business plan information.
