18 AAC 52.540. Official I/M testing

(a) A certified mechanic shall perform official I/M testing as required in Part IV of the program manual. Before providing the motorist with an itemized estimate of repairs, the certified mechanic shall confirm that all parts are available for each repair, subject to the repair cost minimum. A certified mechanic may not begin a repair until all parts for that repair are available at the station. If parts are unavailable for one or more repairs, the certified mechanic shall provide the documentation listed in 18 AAC 52.070(e) (17).

(b) The certified station shall issue to the motorist a VIR for each vehicle inspected at that station that indicates whether the vehicle passed or failed its I/M test.

(1) calibrate and maintain each EIS and test equipment in accordance with the calibration and quality control procedures adopted by reference in 18 AAC 52.035(c) (1);

(2) measure the concentration of hydrocarbons, carbon monoxide, carbon dioxide, and oxygen at the tailpipe of a warmed-up vehicle at curb idle and at 2,500 rpm in accordance with test procedures adopted by reference in 18 AAC 52.035(c) (2) or, for non-exempt 1996 and newer model year vehicles, perform the OBDII portion of the I/M test;

(3) use an EIS that has been certified by the department under 18 AAC 52.420 and install and maintain a separate, dedicated telephone line for each EIS as required in the program manual;

(4) compare measured emissions of carbon monoxide and hydrocarbons to the emissions standards in 18 AAC 52.050 or the alternative standards established under 18 AAC 52.055 or, for 1996 and newer model year vehicles not exempted under 18 AAC 52.050(a) (1), perform the OBDII portion of the I/M test;

(5) perform visual inspection and functional tests on 1975 through 1995 model year vehicles and, as required by the implementing agency, on model year 1996 and newer vehicles for the presence and proper operation of the following emissions-related parts:

(A) positive crankcase ventilation (PCV) valve;

(E) emissions control system warning lights;

(F) oxygen sensor;

(G) major vacuum leaks;

(H) manifolds and ignition;

(I) intake air heater;

(J) carburetor or fuel injection system;

(K) early fuel evaporation (EFE) system;

(L) exhaust gas recirculation (EGR) system; and

(M) fuel evaporative control system;

(6) test exhaust emissions at curb idle and 2500 rpm of all vehicles subject to the I/M program, as determined by the implementing agency under 18 AAC 52.035(b) ; and
