1. A. Equipment used to perform emissions testing shall meet the requirements for the type of testing a fleet station is licensed to perform.

2. B. A fleet station’s gas analyzer shall not be used for an official emissions inspection if:

   1. 1. The calibration gases are not read within the following tolerances:

      1. a. Within plus 0.50% CO to minus 0.25% CO in the range from 0 to 2% CO; and
      2. b. Within plus 60 PPM HC to minus 30 PPM HC in the range from 0 to 500 PPM HC when read as N-HEXANE.
   2. 2. The calibration gases are not read within the manufacturer specified tolerances;
   3. 3. There is a leak in the sampling systems or the calibration port; or
   4. 4. The sample handling system is restricted.
3. C. The fleet emissions testing station shall acquire and utilize calibration gases with assigned HC and CO concentrations to calibrate fleet emission analyzers.
4. D. A state inspector shall fail a fleet emissions analyzer if the analyzer does not meet the requirements of this Section. A fleet emission inspector shall not use the analyzer for inspection until the analyzer is cleared for return to service by a state inspector.

5. E. A state inspector shall conduct performance audits to determine whether a fleet emissions inspection station is correctly performing inspections and functions related to inspections as follows:

   1. 1. Overt audits at least two times each year that include:

      1. a. A check for the observance of appropriate document security;
      2. b. A check to see that required recordkeeping practices are being followed;
      3. c. A check for licenses, certificates, and other required display information;
      4. d. An observation and evaluation of each vehicle emissions inspector’s ability to perform an inspection; and
      5. e. A check to ensure all emissions testing equipment is calibrated and operating correctly.
   2. 2. Fleet station and vehicle emissions inspector records shall be reviewed at least monthly to assess fleet performance and identify any problems, potential fraud, or incompetence.
   3. 3. If a vehicle emissions inspector fails an audit, the vehicle emissions inspector’s license may be suspended or revoked according to R18-2-1016(A)(4).
   4. 4. Covert audits may be performed as necessary to confirm compliance with this Article.
