The California Air Resources Board has approved regulations to reduce diesel pollution in the state. The new rules target older heavy-duty diesel trucks in California. KPBS Environmental Reporter Ed Joyce has details.
Older polluting diesel trucks, school buses and other large vehicles would be retro-fitted or replaced.
The vote came after an all-day hearing with testimony from more than 100 people including representatives from school districts, farmers and trucking groups.
Julie Sauls with the California Trucking Association says the new rules are too costly.
Sauls: I think it is extremely important that you also take into account the income levels that this industry is currently facing and their ability to make these investments.
State grants and loans are available to help fund the improvements, which begin taking effect in 2011.
The air board says diesel truck pollution has been estimated to account for 70 percent of the cancer risk from the air we breathe.
Health advocates say the new rules will save more than 9,400 lives and cut billions of dollars in health costs each year.
