This plan supports the mission of the Governorís 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 Governorís office.
