Chapter 10.12 ENHANCED VEHICLE EMISSIONS INSPECTION MAINTENANCE PROGRAM

A. The following schedule gives the maximum allowable concentrations for Carbon Monoxide (CO) and Hydrocarbons (HC) for both cars and trucks as determined by an approved infrared gas analyzer using the prescribed procedures. The effective date for these cut points is January 1, 1998.

1979 TRUCKS AND NEWER 8,500 POUNDS GVWR OR LESS

NOTE: These should be considered as "cut points" for maximum allowable emissions levels. Vehicles must never be reset to these emission levels when readjustments are made, but rather shall be adjusted using manufacturer's specifications. By using manufacturer's specifications, the emissions levels should be well below the "cut points".
