Advisory Information
COMPLIANCE ADVISORY
Portable Diesel Engine Airborne Toxic Control Measure

Please note that the California Air Resources Board (CARB) has issued Advisory #347 (attached) stating plans to revise the Airborne Toxic Control Measure for Diesel Particulate Matter (ATCM) from Portable Engines Rated at 50 Horsepower and Greater. The changes will impact the fleet average emission standards for diesel particulate matter (DPM) that become effective in 2017 and 2020. CARB also plans to revise the Statewide Portable Equipment Registration Program Regulation (PERP Regulation) to complement any changes made to the ATCM. The changes are being considered because CARB has determined that widespread compliance with the 2017 and 2020 fleet average standards for DPM may not be feasible.

This is to confirm that, as recommended by CARB in Advisory #347, the Imperial County Air Pollution Control District will not be enforcing the 2017 ATCM fleet average emission standards and related reporting requirements until the regulatory amendments have become effective. All other PERP regulation and ATCM provisions remain in effect, including current engine eligibility requirements, and provisions requiring all uncertified (Tier 0) equipment to be removed from service no later than January 1, 2017.
