California Accidental Release Prevention Program (CalARP)
The California Accidental Release Prevention (CalARP) Program protects people from the release of regulated substances into the environment.
Regulated substances are chemicals that pose a major threat to public health and safety or the environment because they are highly toxic, flammable or explosive. Some businesses in San Mateo County store or handle regulated substances during the course of their work.
Examples of regulated substances are:
- Chlorine gas
- Nitric acid
You can find regulated substances listed on three separate tables: two federal and one state. The tables differ with regard to the type and amount of a regulated substance subject to regulation. Your business is responsible for determining which table list to use. Contact Environmental Health Services at (650) 372-6200 to discuss the regulated substances and their respective threshold quantities, and to determine if a Risk Management Plan (RMP) must be completed.
Prior to submitting a RMP, businesses must complete a CalARP Program registration form and submit it to Environmental Health Services. After you register the regulated substance, you will need to prepare and submit a RMP within the allotted time frame.
Risk Management Plans
Subject businesses, also referred to as stationary sources, and must develop a RMP to prevent or minimize an accidental release of a regulated substance. The RMP requires that businesses develop and maintain emergency response procedures to be implemented if a release of a regulated substance occurs.
RMPs describe potential offsite consequences to public and environmental receptors such as schools, residential areas, hospitals, and elderly and childcare facilities.
RMPs must include procedures for:
- Proper storage and handling of regulated substances
- Training staff
- Operating and maintaining process equipment
- Inspections to determine that regulated substances are stored safely
- Emergency response to an accidental release
Submitting a Risk Management Plan
If the regulated substance you handle exceeds the threshold quantity on either federal table, your business should have must submitted a RMP by June 21, 1999. If an RMP was not submitted by this date and one was required, contact Environmental Health Services to discuss your options for completing a RMP.
If your business handles a regulated substance that exceeds the threshold quantity on the state table, you must submit a RMP upon request by Environmental Health Services.
Businesses that are proposing to modify their processes with a regulated substance above the threshold quantity are required to notify Environmental Health Services to determine whether or not the RMP should be revised.
For more information on the CalARP Program, call Environmental Health Services at (650) 372-6200 or the Governor’s Office of Emergency Services (OES) at (916) 845-8510, or visit the Governor’s Office of Emergency Services website.
