California Air Quality Regulations

In 2014 California air quality regulators delayed the deadlines for heavy-duty trucks to follow one of the most difficult diesel air pollutions of the country.

The state Air Resources Board extended the deadline to upgrade to better, cleaner models of trucks or install filters which would be less damaging to the environment. The aim of the regulations was to reach the goal of decreasing the diesel emissions to 85% by 2020. The law adopted in 2008 was directed towards 1 million diesel trucks that operate in California, which are among the most dangerous sources of California’s air pollution.

According to a recent study done published by the Department for Energy and Climate Change of the United Kingdom, Diesel fumes damage our health more than petrol engines. Accordingly, they have to be filtered more carefully and maintained well. The particles that occur from diesel engines can cause serious health issues, by getting stuck in the lungs. These side effects are mostly showcased in communities nearby ports, highways and places of heavy traffic.

“All children, not just susceptible subgroups, are potentially affected by traffic exposure”.

“Someone suffering a pollution-related deficit in lung function as a child will probably have less than healthy lungs all of his or her life. And poor lung function in later adult life is known to be a major risk factor for respiratory and cardiovascular diseases.” W. James Gauderman, Ph.D., associate professor of preventive medicine at the Keck School of Medicine of USC. stated.

The new EPA requirements (Environmental Protection Agency) enforce a monitoring strategy over 100 cities across the United States, in areas nearby highways and freeways. The pollution level has already been found to be very high in Southern California. Moreover, it is 10 times higher near the freeways of Los Angeles than anywhere else in the city.

“We understand that cleaning up trucks is expensive, but somebody has to pay,” a community college student from Oakland, stated in an interview .”Right now we’re paying with our health and that’s not right.”


Oil Inc and a Fresno-based company John R. Lawson Rock sued the state air board over the 2014 decision to delay the deadlines for smaller truck companies, farmers etc. 2 years later, in 2016 Fresno County Superior Court Judge Mark W. Snauffer  ruled that the extension of the deadline has to be canceled, due to the business and environmental consequences. Those companies who have already met the state demands have undergone enormous expenses. The other small ones, who have filed for a deadline extension have increased their revenue and have failed meet the state demands.

The chief executive of California Trucking Assn Shawn Yadon, said that the air board “was basically picking winners and losers —  and the losers ended up being the operators and carriers who stepped up to comply with the rules at great cost.”
