San Diego air meets standards

May 28, 2013 by Guest Writer

The U.S. Environmental Protection Agency announced that San Diego County in Southern California has met the 1997 national health-based air quality standard for smog, also known as ground-level ozone.

Over the past decade, emissions standards and innovative programs have reduced smog forming pollution including nitrogen oxide (NOx) by 25 percent and volatile organic compounds (VOC) by 15 percent. California cars, trucks and sports utility vehicles today produce 80 percent less smog-forming pollution than they did 15 years ago.

San Diego County meets the 0.08 parts per million federal standard for ozone, but the area has yet to attain the more stringent 0.075 parts per million ozone standard adopted in 2008.
