CARB Regulations

Low Permeation Hose - Compliance Dates

The California Air Resources Board (CARB) is more than just a statewide agency. CARB regulations are followed by all of the states except one (Missouri) and by several other countries (mostly in Europe). The federal government charged CARB with the responsibility of creating and implementing a testing program which certifies vapor recovery products. The federal government also gave the states the option of following the CARB regulations or implementing their own testing program and adopting their own regulations. The only state to adopt their own program was Missouri. As a result, CARB is the de facto federal program for all other states.

Shields, Harper's CEO, Bart Scowley, represents the Petroleum Equipment Institute (PEl) on CARB's Enhanced Vapor Recovery (EVR) committee. Significant changes are being implemented in both Phase I and Phase II vapor recovery equipment. The enforcement of CARB's regulations is carried out by local agencies in the various states. Agencies vary from state to state.

New developments as a result of CARB's new EVR regulations include the fact that some states have received EPA permission to continue use of some decertified CARB vapor recovery equipment. To view the up-to-date position of each state, visit the PEI Website.
