Attention Contractors!

CIAQC submits Comment Letter to ARB (California Air Resources Board)

Amendments to the Statewide Portable Engines Registration Program Regulations (PERP) & Airborne Toxic Control Measure for Diesel Particulate Matter (ATCM)

Background:

ARB adopted the ATCM in 2004 to protect public health by controlling emissions from nearly all diesel fueled portable engines rated at 50 horsepower and greater operating in California. The current ATCM requires subject fleets of engines to meet a series of fleet average emission standards for diesel particulate matter (DPM). The ATCM fleet standards became effective in January 2013, and will become progressively more stringent in January 2017 and in January 2020. This regulation is part of the State's Diesel Risk Reduction Plan to reduce DPM.

ARB adopted the PERP Regulation in 1997 to offer portable equipment owners a permit/registration option recognized in all 35 local air districts. A permit, or registration, may otherwise be required from each local air district in which the engine/equipment unit would operate. Under PERP, only the most current tier engines, and engines manufactured under the flexibility provisions (flex engines), are eligible for initial engine registration with certain exceptions for auxiliary engines in specific categories.

In December 2015, ARB released a regulatory and enforcement advisory announcing our intention to revise the 2017 fleet standards and advising local air districts to suspend enforcement activities regarding those standards and related reporting requirements.

ARB plans to revise the fleet average emission standards for DPM that would become effective in 2017 and 2020. Revisions made to the ATCM will also be reflected in the PERP Regulation in order to complement the two regulations: This public workshop follows three workshops conducted in March 2016, which initiated the regulatory process, and is intended to provide an opportunity for the public to comment on proposed regulatory language that includes alternatives to the current fleet averages. ARB invites any comments, suggestions, and recommendations which encourage development of revised standards that will better promote and protect public health while considering economic impacts to regulated fleets. The Board is scheduled to consider this item at its March 2017, public hearing.
