Fire & Rescue California Accidental Release Prevention
The California Accidental Release Prevention Program, or CalARP, is the Federal Risk Management Plan (RMP) Program with additional state requirements, and lower chemical thresholds. These regulations include the requirements of the Code of Federal Regulations (CFR) title 40, part 68, Chemical Accident Prevention Provision. With the additions and modifications as described in the California Code of Regulations Title 19, Division 2 Chapter 4. Stationary sources covered by these regulations must develop and implement a RMP that includes a hazard assessment (off-site consequence analysis) and an emergency response program that must be registered with the Environmental Protection Agency (EPA).
California regulations adopted the federal EPA RMP and replaced California’s original Risk Management and Prevention Program (RMPP) regulations. Facilities that have an RMPP in place must continue to maintain and implement the RMPP until a written request is made by the local Administering Agency (AA). For new facilities, the threshold for CalARP requirement is when the refrigerant charge of anhydrous ammonia is greater than 500 pounds.
At or above 10,000 pounds of ammonia charge: Process Safety Management (PSM) of acutely hazardous materials must comply with CCR title 8, section 5189. This was developed to prevent or minimize the consequences of catastrophic release of toxic, reactive, flammable, and explosive chemicals. OSHA has issued the PSM regulations under 29 CFR 1910.119 as an intention to reduce the risks to which on-site employees are exposed.
