Ariz. Admin. Code § R18-2-1025 - Inspection of Contractor's Equipment and Personnel

A. State inspectors shall conduct performance audits to determine whether a state station is correctly performing all inspection and functions related to inspections as follows:

1. In Area A:

a. Automated emission analyzers, calibrated and maintained according to "IM240 and Evap Technical Guidance," shall be inspected using state station field calibration gases at least once every other month.

b. Opacity meters shall be inspected for accuracy using a neutral density filter at least once each month.

c. During audits, a check shall be made for equipment tampering, worn instrumentation, blocked filters, and other conditions that would impair accurate sampling.

2. In Area B:

a. Automated emission analyzers shall be inspected using state station field calibration gases at least two times each month.

b. Opacity meters shall be inspected for accuracy using a neutral density filter at least two times each month.

c. During audits, a check shall be made for tampering, worn instrumentation, blocked filters, and other conditions that would impair accurate sampling.

d. Functional checks of dynamometer accuracy including roll speed and power absorption shall be performed at least quarterly.

1. Overt audits shall be completed at least two times each year for each inspection lane. Overt audits shall 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. If a vehicle emissions inspector fails an audit, the vehicle emissions inspector's license may be suspended or revoked under R18-2-1016(A)(4).

3. Vehicle emissions inspection records shall be reviewed at least monthly to assess station performance and identify any problems, potential fraud, or incompetence.

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

B. Equipment used to perform a transient loaded emissions test, shall be audited at least twice a year for all of the following:

1. Constant volume sampler critical flow and calibration;

2. Optimization of the flame ionization detector fuel to air ratio using methane;

3. Proper dynamometer coast down, roll distance, and inertia weight;

4. Ability to detect background pollutant concentrations;

5. Evaporative pressure test system for accuracy, response time, and other criteria consistent with "IM240 and Evap Technical Guidance;" and

6. Functional gas cap analysis equipment.

C. B. If an equipment audit indicates that equipment is not calibrated and accurate, the equipment shall not be used to conduct emissions testing until it is replaced or repaired.

D. C. Equipment that is removed from testing may be returned to service upon its repair and a state inspector's verification of a passing calibration audit.

E. State inspectors shall conduct performance audits to determine whether vehicle emissions inspectors are correctly performing all inspections and functions related to inspections as follows:

1. Overt audits at least two times each year for each inspection lane:

a. Check for proper document security;

b. Check for required recordkeeping including vehicle emissions inspector licenses; and

c. Observation and written evaluation of each vehicle emissions inspector's ability to perform an inspection.

2. State station and vehicle emissions inspector records shall be reviewed at least monthly to assess station performance and identify any problems, potential fraud, or incompetence.

3. If a vehicle emissions inspector fails an audit under subsection (E)(1) or (E)(2), the vehicle emissions inspector's license may be suspended or revoked according to R18-2-1016(A)(4) .

F. D. A state inspector shall inspect on-road emissions analyzers at least monthly

gas analysis equipment.

G. If an equipment audit indicates that an on-road emissions analyzer is not operating within contractually specified tolerance, the state inspector shall immediately re-audit the failing equipment. If the equipment fails the second audit, the inspector shall immediately notify the contractor and the contractor shall repair or replace the equipment according to subsections (C) and (D).
