Placer County Enjoying Cleanest Air In Years
For immediate release
SACRAMENTO - Take a deep breath and enjoy -- Placer County is enjoying its cleanest air in years. "There's no doubt about it, as the summer air pollution season draws to an end the reports are coming in from across California -- 1997 is a banner year for air quality," said John Dunlap, chairman of the California Air Resources Board (ARB).
Enjoying this clean air trend along with the rest of the state, Placer County showed remarkable air quality gains in 1997, highlighted by a reduction in lung-damaging ozone, according to Placer County Air Pollution Control Officer Richard Johnson.
"From 1995 through 1996 we went over the state ozone standard (.09 parts per million) an average of 29 times each year," Johnson said. "So far this year preliminary figures show we exceeded the state standard on just nine days -- a decrease of about 70 percent," Johnson said.
ARB Chairman Dunlap attributed the state-wide clean air trend to a number of factors: "California has the world's cleanest gasoline, the cleanest diesel fuel and the cleanest cars and we've continued to require automakers to reduce emissions from new cars year-after-year." Dunlap also noted that local air districts, such as the Placer County District, have worked to reduce air emissions from businesses and industry.
The ARB chairman pointed out that the clean air gains come at a time when California is celebrating the 50th anniversary of air pollution control programs. These air quality programs date back to 1947, when Gov. Earl Warren signed legislation giving California counties the authority to begin their own air pollution control programs. The pay-off from these programs can be seen in state-wide clean air progress. A review of air quality gains just in the past 25 years shows:
- Average ozone levels down 30%.
- Carbon monoxide levels down by 60%.
- Sulfur dioxide down 80%.
- Ambient lead levels down by 97%.
"These clean air gains have been made during a period when the state's population and number of automobiles have skyrocketed -- 20 million more cars and 21 million more people since 1947," Dunlap said. However, the ARB chairman said, California still faces the nation's greatest clean air challenge. "More than 90 percent of Californians live in areas that exceed federal standards for ozone," he said.
Dunlap suggested simple measures such as keeping cars and trucks tuned up as steps anyone can take to help the state's efforts toward cleaner air.
