California Accidental Release Program (CalARP)

The California Accidental Release Program (CalARP) is designed to minimize the risk of extremely hazardous substances that potentially cause immediate harm to the public and the environment. It requires the owner/operator of a business handling one or more regulated substance over the State and/or Federal threshold to evaluate and determine the potential impacts of an accidental release. Under the CalARP regulations these facilities must submit a Risk Management Plan (RMP) to the CUPA. The RMP developed by the facility determines the potential accidental factors; and preventative measures and safeguards are implemented into safe operations. RMP submissions include: safety information, process hazard analysis, hazard review, operating procedures, training, maintenance, compliance audits, incident investigations and other documentation supporting the implementation of the program.

Program 1

Processes that contain a regulated material above the State or Federal threshold, but under a worst-case release scenario as defined, would not result in impacting the public and has had no accidents with specific offsite consequences occur within the past five years.

Facilities that are subject to the California Accidental Release Prevention (CalARP) Program are required to submit a Risk Management Plan to Kern County Environmental Health. These plans are available to the public for review by contacting the Kern County Environmental Health Hazardous Materials Programs at 661-862-8740. Each plan describes the prevention programs in place at the facility, hazard assessment, and their emergency response program.

Facilities with operations that are subject to the CalARP Program because of a Program 1 process are required to develop, implement, and maintain the following:

  1. Hazard Assessment
  2. Worst-Case Scenario
  3. Five-year accident history
  4. Emergency Response Program

Program 2

Processes not eligible for Program 1 or subject to Program 3 are placed in Program 2.

Facilities with operations that are subject to the CalARP Program because of a Program 2 process are required to develop, implement, and maintain the following:

  1. Hazard Assessment, including the following:
    • Worst-Case Scenario(s)
    • Alternative Release Scenarios (more likely to occur)
    • Five-Year Accident History
  2. Prevention Programs, including the following:
    • Safety Information
    • Hazard Review
    • Operating Procedures
    • Training
    • Maintenance
    • Incident Investigations

  3. Emergency Response Program

Program 3

Processes not eligible for Program 1 and either subject to OSHA’s Process Safety Management standard under Federal or California OSHA programs or described by one of the ten specified North American Industrial Classifications Standards (NAICS) codes (primarily related to petroleum refining or chemical manufacturing).

Processes at a facility that handle a listed chemical above a specified quantity are subject to the CalARP Program. Facilities with operations that are subject to the CalARP Program because of a Program 3 process are required to develop, implement and maintain the following:

  1. Hazard Assessment, including the following:
