Imperial County Enjoying Cleanest Air In Years
For immediate release
SACRAMENTO - Take a deep breath and enjoy -- Imperial 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, Imperial County showed remarkable improvement in air quality in 1997, highlighted by a major reduction in lung-damaging ozone, according to Imperial County Air Pollution Control Officer Stephen Birdsall.
"From 1994 through 1996 we went over the state ozone standard (.09 parts per million) an average of 76 times each year," Birdsall said. "The preliminary figures we have so far this year shows we exceeded the state standard on 54 days -- a decrease of about 30 percent," Birdsall 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 requiring automakers to reduce emissions from new cars year-after-year." Dunlap also noted that local air districts, such as the Imperial County District, have worked to reduce air emissions from business 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 pollution-control programs.
The pay-off from these programs can be seen in state-wide clean air progress. A review of air quality over 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 our cars and trucks tuned up as steps anyone can take to help the state's efforts toward cleaner air.
