Wis. Admin. Code Department of Transportation § Trans 131.14 - Remote sensing

(1) GENERAL. The contractor shall use remote sensing to measure the in-use vehicle emissions in any county identified under s. 110.20(5), Stats. Any nonexempt vehicle that has passed its last emission reinspection under s. Trans 131.03(11), and fails the remote sensing test by exceeding the remote emission standards under sub. (4), shall have an emission inspection under s. 110.20(9) (g), Stats. Penalty for failure to comply with this section consists of suspension of vehicle registration as set forth in s. 341.63(1) (e), Stats.
(2) WHEN INSPECTION REQUIRED.
(a) The owner or lessee of a nonexempt vehicle that fails the remote sensing test shall have an emission inspection within 45 days of notification of a remote sensing test failure.
(b) Vehicles that fail the remote sensing test, but are scheduled to receive an emission inspection required under s. 110.20(6), Stats., within 90 days of remote sensing test failure, or for which temporary exemptions will expire within 30 days of remote sensing test failure, shall receive notification of the remote sensing test failure but are exempt from the inspection requirements of s. 110.20(9) (g), Stats.
(c) Vehicles that have a valid emission inspection waiver at the time of remote sensing test failure are exempt from the inspection requirements of s. 110.20(9) (g), Stats.
(3) SCOPE AND NATURE OF REMOTE SENSING TEST. The test shall consist of using an open-path infrared sensor to measure the concentration of one or more of the following pollutants present in the vehicle's exhaust:
(a) Hydrocarbons.
(b) Carbon monoxide.
(c) Carbon dioxide.
(d) Oxides of nitrogen.
(4) EMISSION STANDARDS. Vehicles that exceed the standards shown in Table 1 shall fail the remote sensing test:

Note: Changes to these standards may occur either if the USEPA establishes remote sensing standards or if the department's program evaluation indicates that modifications should occur to identify more accurately gross polluting vehicles.

(5) VEHICLE INSPECTION NOTICE. The contractor shall mail a vehicle inspection notice to the owner or lessee of vehicles that fail a remote sensing test conducted under this section. The vehicle inspection notice shall be mailed to the owner's or lessee's address indicated on the department's registration database. The vehicle inspection notice shall include all of the following:
(a) Remote sensing test serial number.
(b) Date, location and time of the remote sensing test.
(c) License plate number.
(d) VIN.
(e) Emission remote sensing test results and standards for the vehicle.
(f) Instructions indicating that the report, together with the vehicle, shall be brought to any inspection station or other authorized inspection facility to receive an inspection as required under s. Trans 131.14(2), if required.
(g) Information describing the remote sensing test.
(h) Explanation of both the legal requirements and registration penalties for failure to comply with an inspection notice.
(i) Other information that the department may decide to include to improve understanding of the remote sensing test.
(6) REMOTE SENSING EQUIPMENT SPECIFICATIONS AND MAINTENANCE.
(a) All equipment utilized for remote sensing emission measurement shall be calibrated and maintained according to the manufacturer's specifications or as superseded by contract.
(b) Remote sensing equipment, personnel and procedures shall be subject to periodic audits by the department under s. Trans 131.11.
