California Accidental Release Prevention (CalARP) Program
The CalARP program is designed to prevent accidental releases of toxic and flammable substances and to minimize the risk of harm from incidents, if they occur. It provides regulators, responders, and the public access to information on chemicals at facilities that pose an offsite risk if released. The program allows the CUPA and the facility to work together to improve chemical safety and protect the public, the environment, and property and for the public to provide input.
Facilities that handle more than a threshold quantity of a regulated substance must develop a Risk Management Plan (RMP). An RMP is a detailed analysis of the potential for accidental release of a regulated substance at a facility and prevention and mitigation measures.
The CUPA (City of San Leandro Environmental Services Section) oversees the CalARP program. Further information about the CalARP program, including FAQs, guidance, and regulation links is available on the California Environmental Protection Agency's website.
Depending on the chemical and the quantity on site, a facility may be subject to both the CalARP program and the federal Risk Management Program. Further information about the federal program may be found on the U.S. EPA website
CalARP Facilities Public Review and Comment Period
New submittals and resubmittals of RMPs are subject to a 45-day public review and comment period after the CUPA deems the RMP complete. RMPs are public records available for review by appointment at the Environmental Services office in City Hall.

The RMP describes the facility's administrative and operational programs to prevent accidents and reduce potential risks associated with handling anhydrous ammonia, which is used as a refrigerant in a closed-loop system that provides cooling for a production process.
The RMP may be viewed by appointment at the Environmental Services office located at 835 E.14th Street, San Leandro, CA 94577. To schedule a review, please submit a request through the Environmental Services Records Review page. Comments may also be sent to this address during review and comment periods.
