U.S. EPA Approves South Coast, San Joaquin Valley Plans for Particle Pollution
The U.S. Environmental Protection Agency is approving California’s air quality plans for fine particles — known as PM2.5 — in the South Coast and San Joaquin Valley. These plans will reduce pollution to the level required by the health based 1997 PM2.5 standard by 2015.
“These air quality plans rely on first-of-their kind requirements for the engines in trucks, ships and construction equipment, impacting almost a million vehicles in California,” said Jared Blumenfeld, EPA’s Regional Administrator for the Pacific Southwest. “Clean air is critical to everyone’s health, especially our children and seniors.”
