The San Joaquin Valley has improved its air quality despite its unique geographical setbacks, according to one expert.
John Cadrett, a compliance manager for the San Joaquin Valley Air Pollution Control District, presented an air quality update to the City Council on Wednesday.
Because of the bowl shape of the Valley, Cadrett said, it is hard to meet the eight-hour standard of 0.07 parts per million and the one-hour ozone standard of 0.09 ppm.
However, carbon emissions from stationary sources have fallen 80 percent since 1980.
Cadrett said winter 2010 and summer 2011 were the cleanest seasons on record.
The Air District's "Healthy Air Living" initiative urges residents to make one change in their lives to continue to reduce emissions: carpool, use public transportation or replace outdated equipment, for example.
"We're asking the public to reach out and do one thing," Cadrett said.
