Aboveground Petroleum Act (APSA)
APSA regulates tank facilities that are subject to the federal SPCC rule or tank facilities with an aggregate storage capacity of 1,320 gallons or more of petroleum in aboveground storage containers or tanks with a shell capacity equal to or greater than 55 gallons. These facilities typically include large petroleum tank facilities, aboveground fuel tank stations, and vehicle repair shops with aboveground petroleum storage tanks. APSA also regulates tank facilities with less than 1,320 gallons of petroleum if they have one or more stationary tanks in an underground area (TIUGA) with a shell capacity of 55 gallons or more of petroleum. In this case, only the TIUGAs are subject to APSA, although there are exceptions. The Act does not regulate non-petroleum products. Facilities with total petroleum storage quantities at or above 10,000 gallons are inspected at least once every three years by a Certified Unified Program Agency. Please visit the California Office of the State Fire Marshall who administers the APSA program for additional information on APSA.

California Accidental Release Prevention Program
Opens a New Window.
There are certain regulated substances, known as extremely hazardous substances, that require extensive emergency planning. The most common regulated extremely hazardous substance found in the county requiring a Risk Management Plan (RMP) is anhydrous ammonia. There are over 400 other chemicals that may require an RMP. Businesses that meet threshold quantities specified by U.S Environmental Protection Agency (U.S. EPA) are subject to both state and federal RMP requirements and shall provide their RMP to both the CUPA and the U.S EPA on the date on which the regulated substance is first present in a process above the federal threshold quantities of the substance.
Facilities that have regulated substances above the State of California thresholds shall submit a RMP to the CUPA on the date on which a regulated substance is first present in a process above the state threshold quantities Every three years the owner must certify compliance of their processes and practices and every five years the owner must update their RMP and reevaluate that their process hazard analysis remains current. There are 9 facilities throughout Napa County that are subject to the regulatory requirements of this program that are inspected triennially. Please visit the California Environmental Protection Agency website for more information on the California Accidental Release Prevention Program.

Technical Reference for Emergency Response
DEH coordinates with emergency response agencies to aid in the identification of chemicals released into the environment during an incident and to ensure their proper remediation.
Napa County Area Plan
The Area Plan program was established in 1986 as a planning tool for local government agencies to respond to and minimize the impacts from a release or threatened release of a hazardous material. It requires creating an Area Plan which:
- Identifies the hazardous materials which pose a threat to the community
- Develops procedures and protocols for emergency response
- Provides for notification and coordination of emergency response personnel
- Provides for public safety including notification and evacuation
- Establishes training for emergency response personnel
- Identifies emergency response supplies and equipment
- Provides for the critique and follow-up after a major incident
Please visit the California Office of Emergency Management Agency website for additional information about the Napa County Area Plan.

Methamphetamine Contaminated Property Cleanup Act of 2005 (California Health & Safety Code (HSC) Chapter 6.9.1)
This act mandates remediation by the property owner and requires the property owner to retain an authorized contractor, as defined in HSC Section 25400.11 (a), to remediate the contamination. It allows remediation of contaminated properties by a city or county in the event a property owner fails to initiate or complete the remediation and imposes specified costs and civil penalties on property owners where there is known or suspected methamphetamine contamination.
