REASONABLE FURTHER PROGRESS (RFP) REPORT
1985/1986
I. GENERAL SM-fAkZY AND CONCLUSIONS
This report covers the progress made during the 1985 and 1986 calendar
years toward implementing the county's 1982 Air Quality Management Plan
(AQMP). The AQMP is equivalent to the Non Attainment Plan (NAP).
The AQMP projects attainment of amtient air quality standards through
reductions in emissions of reactive hydrocarbons (RHC) and carbon monoxide
(CO). The RHC emissions were to be reduced through permitted source, area
source, mobile source, and transportation control measures. CO emissions
were to be reduced through mobile source and transportation control
measures. Table below summarizes the predicted and actual" emission
red-, ctions during each reporting year.

As indicated above the projected RHC emission reductions were not achieved
in 1986. Although, the Reasonable Further Progress (RFP) was attained for
RHC emissions, the air monitoring data from the relatively new Mariposa
station revealed higher ambient ozone concentrations than the ones measured
at the Stockton \Hazelton station and used in the AQMP. Therefore, more
reductions than originally predicted are needed to attain NAAQS. The NAAQS
for ozone was exceeded during Doth of the reporting yeas.
For CO emissions, although RFP was achieved during both reporting years.
There was one day in 1986 during which the NAAQS was exceeded. The air
monitoring data for CO indicates that although average CO concentration
have begun an upward trend, the peak concentrations have sharply decreased
during the past three years.
In light of the above situation, the county has approved implementation of
inspection anti maintenance of light duty motor vehicles. This measure was
listed as "Priority One" contingency strategy in the AQMP. The AIR
pollution Control Board approval in the AQMP. The Air Pollution Control
Board approved this measure and the State Bureau of Automotive Repairs as
the implementing agency for this measure predicts implementation beginning
in August 1988. Based on the experiekice at other areas currently
implementing this measure a 13% reduction in RHC emissions and a 19%
reduction in CO emissions from light duty motor vehicle emissions is
expected upon full implementation.
During both reporting years, the growth related emissions significantly
affected the overall emission reductions. The most significant baseline
emission changes in 1985 and 1986 were related to the pesticide emissions
and motor vehicle emissions. The pesticide emissions were substantially
reduced due to economically motivated shift from petroleum-based pesticides
to synthetic substitutes. Based on the emission inventory data provided by
the Air Resources Board (ARB), due to control measures, a 54%reduction in
RHC emissions has occurred since 1979. On the other hand there has been a
substantial growth related increase in motor vehicle emissions. Based on
the ARB's emission inventory data there has been a 15%increase in light
duty passenger vehicles and a 26% increase in light duty truck use.
Finally, all available data point towards the fact that the District w i 11
be unable to attain National Ambient A i r Quality Standards by the December
31, 1987 deadline. However, vehicle inspection and the maintenance measure
already approved by the District is expected to provide for a large step
towards attainment in a post 1987 measure.
