CalARP Program

alifornia 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.   The reporting process provides regulators, responders, and the public access to information on chemicals at individual facilities, their uses, and accidental release history.  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 engineering analysis of the potential for accidental release of a regulated substance at a facility and any prevention and mitigation measures.

 The CUPA (City of San Leandro Environmental Services Section) implements the CalARP program.  Further information about the CalARP program, including FAQs, guidance, and the text of the current regulations and any proposed amendments 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.  To schedule a review, please submit a request through the Environmental Services Records Review Page.
