Well, lazs. Unfortunately, making stuff up to suit your agenda doesn't mean you have a winning argument, just an interesting one.
According to the ARB analysis, the annual amount of unhealthy air pollution-declined 50 percent in the South Coast Air Basin, home to one-third of the state's population, between 1981 and 1991. During the same time, the highest, peak urban smog (ozone) levels were reduced 25 percent.
The ARB analysis also noted that the air quality improvements were not confined to any one area, but were documented throughout the basin from the coast to the desert.
"Contrary to trends in some other parts of the country, these figures speak for themselves and show that California's effort to improve air quality is well-founded scientifically and is making more progress than other regions of the country," said James D. Boyd, ARB executive officer in releasing the study.
Now I wonder what California had at this time that other States didn't have? Oh yeah! Stricter smog controls for cars!
But here are the facts:
Chronology of events regarding air quality Just a couple of highlights....
1965 Reliable measurements of ozone concentrations began to be recorded. The maximum one-hour ozone concentration for the year in the South Coast Air Basin was 0.58 ppm.
1970 CA's population reached 20 million people. Total registered vehicles exceeded 12 million and vMT was 110 billion. Cumulative CA vehicle emissions for NOx and HCs were 1.6 million tons/year.
1971 ARB adopted the first automobile NOx standards in the nation.
1975 The SCAQMD's maximum one-hour ozone concentration recorded was 0.39 ppm. The area exceeded Stage 1 smog alerts (0.20 ppm) on 118 days. The first two-way catalytic converters came into use as part of the ARB's Motor Vehicle Emission Control Program
1976 The South Coast Air Quality Management District was formed. It included portions of Los Angeles, Orange, Riverside and San Bernardino counties. ARB limited lead in gasoline.
1980 CA's population reached 24 million people. Total registered vehicles surpassed 17 million and vehicle miles traveled is 155 billion. Cumulative CA vehicle emissions for NOx and HC
remain at 1970 levels of 1.6 million tons/year despite a rise of 45 billion in VMT over these 10 years.
