Big Trucks Will Have to Get Cleaner - And Industry Is Fine With That

By Robert J. Bowman, SupplyChainBrain
October 10, 2016

Federal regulators are mandating drastic reductions in emissions from heavy-duty trucks over the next 10 years. And truck manufacturers and big shippers alike are applauding the move.

New standards released by the Department of Transportation and Environmental Protection Agency call for reductions of up to 25 percent in carbon emissions from big tractor-trailer rigs. Smaller cuts will be required of delivery fleets and buses.

The new standards will slash carbon emissions by 1.1bn tons, and oil consumption by 2bn barrels, DOT and EPA are claiming.

Governor Brown Signs SB 32 and AB 197

Attention Contractors! Governor Jerry Brown’s Climate Change agenda took another big leap forward with the passage and signing of SB 32 and AB 197. The summary below provided by the Sacramento Bee is an excellent summation of those bills provisions. Of importance to the construction industry is the shift from stationary sources of greenhouse gases to mobile sources, particularly diesel combustion. While it may take some time and there are ongoing legal challenges that could upset the program, we can anticipate that the credit trading program may expand to include construction equipment and on-road trucks. CIAQC will be very diligent in following this effort as it unfolds next year.

Cal ISO (Independent System Operator) Predicts Power Outages Due to Excessive Heat

Due to record high temperatures throughout the west beginning June 20th, Cal ISO is cautioning businesses and residents in Southern California that power outages may occur over several days due to high demand and a lack of natural gas to fuel the local power plants as a result of the closure of the Aliso natural gas facility in Porter Ranch.

As a precaution, restricted maintenance procedures are in place and the South Coast Air Quality Management District has granted local power plants a 90-day exemption to burn diesel fuel to keep the plants in operation. This event could also trigger “Flex Alerts” which could result in power curtailments for those operations which have agreed to voluntary reductions with their power provider.

Attention: Contractors with Heavy-Duty Diesel Trucks used in Construction

Re: Construction Industry Air Quality Coalition (CIAQC) Survey of Power Take-Off (PTO) Annual Hours of Use

The California Air Resources Board (CARB) is currently preparing amendments to the Truck and Bus Regulation to consider in April 2014.  One of the changes to the regulation CARB is anticipated to make is an increase in the miles per year a truck can travel and still qualify as a low-use vehicle.  CARB is also considering an increase to the limit of hours an engine or power take off can operate annually on a truck and still qualify as a low-use vehicle.  (The hour limitation would not apply for vehicles where the engine is used to power an auxiliary mechanism that strictly loads and unloads cargo from the vehicle - see CARB's description below.)

CARB Press Release: Air Resources Board launches “Gear Up for Clean Truck Month” in August

Statewide enforcement campaign to focus on compliance and education

SACRAMENTO - August may be the dog days of summer, but in California it’s also Gear Up for Clean Truck Month, with the Air Resources Board launching a multi-agency campaign to make sure that trucks traversing the state’s highways are in compliance with state air pollution laws.

"Our goal this month is to do everything in our power to make sure truckers know the rules and that they understand how to comply," said ARB Executive Officer James Goldstene. "All our diesel regulations were adopted with one thing in mind - protecting public health. Focusing on enforcement gives us the chance not only to educate drivers on why the regulations are important but also to ensure that truck owners investing in cleaner equipment are on a level playing field with those who are not playing by the rules."

US EPA Proposes New Particulate Standard for PM2.5

Hearing on Proposed Standard will be held July 19, 2012 in Sacramento, CA

The EPA is proposing to strengthen the national ambient air quality standards (NAAQS) for fine particulate matter (PM2.5). The current annual primary (health) standard for PM2.5 is 15 micrograms per cubic meter (μg/m3). This standard was set in 2006. EPA is now proposing to lower the standard to between 12 and 13 μg/m3 and is also considering comments on lowering the annual average to 11 μg/m3. EPA is proposing to retain the current 24-hour daily standard for PM2.5 and daily standard for PM10. EPA is also proposing to create a new secondary 24-hour standard for fine particulates to protect and improve visibility.

In addition, EPA proposes changes to the ambient air monitoring, reporting, and network design requirements associated with the PM standards. This would include the addition of a "Near-road" component to the PM2.5 monitoring and compliance network.

California Air Resources Board to Consider Major Changes to Off-Road Equipment and On-Road Truck Regulations at December Hearing

On Friday December 17, 2010, the California Air Resources Board (CARB) will consider making significant changes to the Off-Road Equipment Regulation and modifications to On-Road Heavy-Duty Truck Regulation.  The proposed changes will help reduce the enormous costs contractors must bear to comply with these regulations.  The changes to the Off-Road Regulation are expected to provide a larger measure of relief from the current rule requirements than will those proposed for the On-Road Truck Regulation.  While the proposed changes to the truck regulation are a move in the right direction, the Construction Industry Air Quality Coalition (CIAQC) does not believe they go far enough to help the construction industry still suffering from the devastating impacts of the economic downturn.  For this reason, CIAQC is asking CARB to increase the low-use mileage threshold for trucks owned by contractors and those used to support the construction industry from 1,000 to 15,000 miles per year.

CARB Admits Huge Error! Attend Upcoming Workshops to Learn More.

California Air Resources Board (CARB) has scheduled a series of workshops (see schedule below) to review its most recent NOx and PM2.5 emissions inventories for the Off-Road Regulation. The updated inventories are roughly 20 percent of what they were originally estimated to be when the regulation was initially developed and adopted in 2007. The lower emissions inventory is attributable largely to revised fuel usage data, adjusted equipment load factors and an overall fleet that is smaller and newer than previous CARB estimates.
