The Area Plan is a requirement for local government agencies used in response to, and to minimize impacts from a release or threatened release of a hazardous material.  CalEPA is the oversight agency for the Hazardous Materials Business Plan (HMBP) program, which includes the Area Plan. The Certified Unified Program Agencies (CUPAs) and/or Participating Agencies (PAs) are responsible for developing the Area Plan in coordination with local emergency response agencies to establish a plan for emergency response in the event of a release or threatened release of a hazardous material within their jurisdiction.

The Area Plan program requires CUPAs to create a plan that:

• Identifies hazardous materials that pose a threat to the community;
• Develops procedures for emergency response;
• Provides for notification and coordination of emergency response personnel;
• Provides for public safety, including notification and evacuation;
• Establishes training for emergency response personnel;
• Identifies emergency response supplies and equipment; and
• Provides for feedback and follow-up after a major incident.
