Attention Contractors! California Air Resources Board to consider modifications to Truck and Bus Regulation on April 24, 2014

The California Air Resources Board (ARB) will hold a public hearing to consider the adoption of amendments to the Regulation to Reduce Emissions of Diesel Particulate Matter, Oxides of Nitrogen and other Criteria Pollutants from In-Use Heavy-Duty Diesel-Fueled Vehicles (Truck and Bus Regulation) on April 24, 2014.  The hearing will begin at 9:00 a.m. at ARB located at 1001 I Street, Sacramento, CA 95814, in the Byron Sher Auditorium.  Directions:

ARB is proposing to add a new compliance option that adjusts the timeline for the installation of diesel particulate filters for low-use work trucks (including construction trucks) that travel less than 20,000 miles per year.  ARB is also proposing to expand the Low-Use Vehicle Exemption for trucks that operate fewer than 5,000 miles per year.  There are several other provisions to the existing regulation that ARB is proposing to modify.  Click here for a summary of the proposed changes and the hearing notice.

The public comment period for the proposed changes is currently underway.  For written comments to be considered by the ARB Board, they must be submitted no later than 5:00 p.m. on April 21, 2014.  Oral and written comments will also be accepted at the hearing.

The Construction Industry Air Quality Coalition (CIAQC) offered recommendations to ARB about how to improve the Truck and Bus Regulation in November 2013 (click here to read the letter).  CIAQC believes the ARB proposal does not offer enough relief to the construction industry given the effects of the slow economic recovery affecting contractors.  Therefore CIAQC is currently developing additional comments based on the proposed amendments and will post them on its website in the coming days.

For questions about the proposed amendments, ARB provides the following contacts:

Inquiries concerning the substance of the proposed amendments to the Truck and Bus regulation may be directed to the designated agency contact persons, Ms. Beth White, Manager of the On-Road Compliance Assistance Section, at (916) 324 1704, or Ms. Jacqueline Johnson, Air Pollution Specialist, at (916) 323-2750.

These signatory contractor organizations, through the Southern California Industry Funds, created CIAQC to help their members understand and navigate the ever-increasing web of government environmental regulation under which they operate their businesses and build our communities, our infrastructure and the environmental systems that will enhance California’s future.

Today several organizations and individual construction firms throughout the state are active in CIAQC. Member associations now also include the Associated General Contractors America – San Diego Chapter, Inc., California Construction Trucking Association, United Contractors, and the California Rental Association.

CIAQC assists the construction industry and regulatory agencies in the development of environmental regulatory strategies that will balance the goals of a healthy environment and a healthy local economy with the least adverse impact on the construction industry.
