State regulators adopt tough rules requiring huge cutbacks in fumes from construction industry equipment. Next up: big trucks. California’s diesel-powered bulldozers, scrapers and other heavy construction equipment must be retrofitted or replaced over the next 13 years to reduce the air pollution that sickens tens of thousands of residents every year, state regulators decided Thursday according to the Los Angeles Times.
Under tough new rules adopted by the Air Resources Board, California is the first state to make construction companies fix existing diesel-powered machines. Heavy equipment can last 30 years or more, so without the new mandate, it would take decades for fleets to upgrade to cleaner equipment.
Although the fumes are most often associated with big trucks and buses, 20% of California’s diesel pollution comes from the construction industry. Building, mining and airport vehicles are responsible for an estimated 1,100 premature deaths statewide every year and more than 1,000 hospitalizations for heart and lung disease, along with tens of thousands of asthma attacks, scientists say.
The air board’s new rules will slash diesel soot — also known as particulate matter — from construction equipment by 92% over 2000 levels. Smog-forming nitrogen oxides will be cut by more than a third. And greenhouse gases, a byproduct of fuel burning, also will drop as a result of a ban on idling equipment.
