The San Joaquin Valley, and nearby Yosemite, Sequoia and Kings Canyon National Parks, have some of the dirtiest air in the nation. Much of this pollution comes from fine particle pollution within the valley, which is not only unhealthy to breathe, but also severely limits otherwise scenic vistas in and around our national parks.

Thankfully, we have one of the best opportunities in years to clean the air, as local and state air agencies develop a new plan to control particulate pollution in the valley.

Take action! Tell the San Joaquin Valley Air Pollution Control District and the California Air Resources Board to take strong, swift action to significantly reduce fine particle air pollution that protects people and parks.
