We have an average failure rate AND high follow up pass rate - a higher performing station.

4: Final Addendum and Evaluation

http://www.arb.ca.gov/msprog/smogcheck/march09/addendum.pdf

Please note report key findings page 3

about 1 in 5 failed a roadside test within a year of passing an initial test.

about 1/2 failed a roadside test within a year of passing a retest.


5:   Sierra Report: Evaluation of the Smog Check Program

http://www.arb.ca.gov/msprog/smogcheck/march09/roadsidereport.pdf

Please note:

tables 4-1 & 4-2 & 4-3 PDF pages 22-23 showing significantly high roadside failure rates AFTER PASSING a smog test - about 20% after passing an initial test or about 50% after passing a retest.

Station Performance Analysis PDF pages 32 - 36.

Table 5-1 PDF page 35 showing emissions benefits if all stations performed at a higher standard - Please note this is tons per DAY. ROG is organic gases such as HC (hydrocarbons such as gasoline). If the pollutants measured (Hydrocarbons, Carbon Monoxide, and Nitrous Oxides are all counted, a huge reduction in pollution could be obtained by raising the standard of testing.

If all stations performed at the level of the top 12% of stations, a pollution reduction of near 70 TONS PER DAY (600 TONS if carbon monoxide is included) is achievable.

If all stations performed at the level of the top 25% of stations, a pollution reduction of over 50 TONS PER DAY  (467 TONS if carbon monoxide is included) is achievable.

Total reductions would be significantly higher when the newer vehicles are included (1996 and newer)
