Refinery Air Monitoring Assessment Plan Released -- July 2013


ARB and the California Air Pollution Control Officers Association (CAPCOA) released a plan to assess emergency air monitoring capabilities in communities near petroleum refineries throughout the State. This assessment is now in progress.

The 15-month project will be conducted collaboratively with local air monitoring agencies, emergency response agencies, and refineries. It will evaluate and make recommendations on the potential need for additional resources including equipment, services, staffing, and training to support local air emergency response programs.

This plan supports the mission of the Governor’s Interagency Working Group on Refinery Safety to improve public and worker safety through enhanced oversight of refineries, and to strengthen emergency preparedness in anticipation of any future incident. The Working Group consisted of participants from 13 agencies and departments, as well as the Governor’s office.

The plan, entitled Air Monitoring for Accidental Refinery Releases: Assessment of Capabilities and Potential Improvements Project Plan - July 2013 is available here.
