Working with California's Strict and Varying Emission Standards

Posted by Rypos on Oct 1, 2019 1:00:00 PM



When it comes to diesel emissions, everyone knows California has extremely stringent regulations.   The difficult piece is understanding the rules and their varying nuances, and then how it applies to your own equipment as well as your subcontractor’s.  Diesel particulate matter is considered a carcinogen, resulting in a myriad of health and respiratory issues, and possibly contributing to the ever-increasing cancer rates.

California Air Resource Board's (CARB) regulations impact both stationary and mobile diesel engines. Trucks and trailers with TRU's older than 7 years are required to either repower or install DPFs.  All heavy-duty vehicles entering California are inspected for emissions compliance at the border, then again at some weigh stations and may be subject to random roadside inspections.

The U.S. Environmental Protection Agency (EPA)has levied fines against two of the nation's largest fleets.  As a result of violating California Air Resources Board regulations, they are required to pay the penalty because they failed to install emissions controls on some of their heavy-duty diesel trucks. 

According to the EPA, from 2013 to 2016 one company operated a fleet without the required DPF systems and also failed to verify that the 3rd party carriers the Company had hired were incompliance with current regulations.  This resulted in the Company being required to pay a $125,000 penalty and spend $350,000 on air filtration projects at schools located near freeways in the Los Angeles area.

Another freight line operated trucks in California, between 2013 and 2016, without the required Diesel Particulate Filters systems.  According to the EPA, the Company also failed to verify carriers it had hired. The Company was issued a $100,000 penalty and must spend an additional $225,000 on air filtration projects at schools.

Doing business in California requires compliance with our Country’s most strict and varying emission standards.  Installing exhaust aftertreatment is a small cost for doing business in the State, cleaning the air, and avoiding fines of $5,000 to $10,000 per violation, per day, if your engines, fleet, or subcontractors are not in compliance.
