County Ordinance Chapter 450-8 expands on the California Accidental Release Prevention (CalARP) Program for facilities meeting the following:

  • The facility is within an unincorporated area of the County
  • The facility is either a petroleum refinery or chemical plant
  • The facility is required to submit a Risk Management Plan (RMP) to the U.S. EPA and Contra Costa County Health Service (CCHS)
  • The facility has at least one Program 3 process

The six facilities currently subject to the County's Industrial Safety Ordinance (ISO) include: Air Products (within the Shell Refinery), Air Products (within the Tesoro Refinery), Phillips 66 Rodeo Refinery, Air Liquide-Rodeo Hydrogen Plant, Shell Oil Martinez Refinery and Tesoro Golden Eagle Refinery.

The City of Richmond has adopted an Industrial Safety Ordinance (Municipal Code Chapter 6.43, RISO) and is identical to the County's Industrial Safety Ordinance after City of Richmond in 2013 and 2014 adopted the 2006 and 2014 County amendments respectively. The two facilities located in the City of Richmond that are subject to this ordinance include: Chevron Richmond Refinery and Chemtrade Richmond Works.
