Frequently asked questions

What is a CUPA, and what is an HMBP?

California's Certified Unified Program Agencies (CUPAs) administer hazardous-materials programs at the local level. Any business that handles hazardous materials at or above 55 gallons of a liquid, 500 pounds of a solid, or 200 cubic feet of a compressed gas must prepare a Hazardous Materials Business Plan (HMBP) — covering chemical inventory, a site map, emergency response procedures, and employee training.

What is CERS?

The California Environmental Reporting System (CERS) is the statewide online portal where HMBPs, hazardous-materials inventories, and other Unified Program submittals are filed and certified. Most CUPAs require annual electronic certification through CERS.

When do I need a CalARP Risk Management Plan?

If your facility handles a regulated substance above its listed threshold quantity — for example anhydrous ammonia or chlorine — the California Accidental Release Prevention (CalARP) program requires a Risk Management Plan that includes offsite consequence analysis and a formal prevention program. We determine applicability and build the plan when it's triggered.

How often must the HMBP be updated?

The HMBP must generally be reviewed and certified annually in CERS. Inventory changes typically must be updated within 30 days of a significant change, and emergency contacts must be kept current. Local CUPAs may impose additional or stricter timelines.

What are the penalties for non-compliance?

CUPA inspections are routine, and missing, outdated, or inaccurate HMBP/CERS submittals draw violations and administrative penalties. We bring you current across your CUPA, CERS, and (where applicable) CalARP obligations and keep the program maintained.
