Ariz. Admin. Code § R18-2-1026 - Inspection of Fleet Stations

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

1. Emission analyzers shall be inspected using field calibration gases at least quarterly.

2. Opacity meters shall be inspected using a neutral density filter at least quarterly.

3. Equipment for transient loaded emissions tests shall be inspected according to R18-2-1025(A) and (B) .

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

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

a. Within plus 0.50% CO to minus 0.25% CO in the range from 0 to 2% CO; and

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. The calibration gases are not read within the manufacturer specified tolerances;

3. There is a leak in the sampling systems or the calibration port; or

4. The sample handling system is restricted.

C. The fleet emissions testing station shall acquire and utilize calibration gases with assigned HC and CO concentrations to calibrate fleet emission analyzers.

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.

E. The Department shall assign HC and CO concentrations to a calibration gas submitted by a fleet station emission analyzer technician and purchased from a private source.

F. A state inspector shall tag a fleet station emission analyzer if the analyzer does not meet the requirements of this Section. The fleet vehicle emissions inspector shall not use the analyzer for inspection until the tag is removed by a state inspector or an analyzer repair person certified under R18-2-1028 . The tag shall be in the form of a U.S. postcard and contain the information listed in R18-2-1027(E) .

G. An analyzer tagged under subsection (F) shall not be returned to service until its accuracy is verified by a state inspector or an emissions analyzer repair person certified under R18-2-1028 .

H. A fleet station is responsible for periodic maintenance and calibrations of its emissions analyzers. Repair and maintenance requirements are prescribed in R18-2-1019 .

I. If a state inspector has approved its use, a fleet station may lease or borrow an emission analyzer for official inspections for up to six months while the station's approved analyzer is being repaired.

J. Fleet station analyzers used for transient loaded tests shall comply with and be quality control checked according to "IM240 and Evap Technical Guidance." All other fleet station emission analyzers used for emissions inspections are required to read the calibration gases within the following tolerances:

1. Within plus 0.50% CO to minus 0.25% CO in the range from 0 to 2% CO;

2. Within plus 1.00% CO to minus 0.50% CO in the range from 2% to 10% CO;

3. Within plus 60 PPM HC to minus 30 PPM HC in the range from 0 to 500 PPM HC when read as N-HEXANE; and

4. Within plus 200 PPM HC to minus 100 PPM HC in the range from 500 to 2,000 PPM HC when read as N-HEXANE.

K. A fleet station opacity meter used for emission inspections is required to read the equivalent opacity value of neutral density filter within [DAGGER]; 5% opacity at any point in the range of the meter.

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

a. A check for the observance of appropriate document security;

b. A check to see that required recordkeeping practices are being followed;

c. A check for licenses, certificates, and other required display information;

d. An observation and evaluation of each vehicle emissions inspector's ability to perform an inspection; and

e. A check to ensure all emissions testing equipment is calibrated and operating correctly.

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. 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. Covert audits may be performed as necessary to confirm compliance with this article.
