(am)
1. The emissions test and equipment inspection of nonexempt vehicles may be performed by persons under contract with the department. Each such contract shall require the contractor to operate inspection stations, which may be permanent or mobile, for a minimum of 3 years and shall provide for equitable compensation to the contractor if the operation of an inspection and maintenance program within any county is terminated within 3 years after the inspection and maintenance program in the county is begun. No officer, director or employee of the contractor may be an employee of the department. The department may contract with any person, including any person engaged in the business of selling, maintaining, or repairing motor vehicles or of selling motor vehicle replacement or repair parts. The department shall require the contractor to operate a sufficient number of inspection stations, permanent or mobile, to ensure public convenience in those counties identified under sub. (5).
1m. Each contract under subd. 1. may authorize or require the contractor to install and operate self-service inspection stations and may allow the use of different methods for emissions testing and equipment inspection, consistent with methods established under par. (bm), than those used at inspection stations that are not self-service.
2. The department may require the contractor to test the fuel efficiency of nonexempt vehicles during emission inspections.
3. The department may delegate to the contractor specified registration functions of the department under ch. 341. The department may direct the contractor to perform specified registration functions under ch. 341.
4. The department may delegate to the contractor functions associated with the issuance of a temporary operating permit under sub. (10) (b) or the waiver of compliance under sub. (13) (a) or both.
6. The contractor shall collect, maintain and report data as the department requires. The department shall reserve the right to enter and inspect test station premises, equipment and records at all reasonable times in the discharge of its administrative duties.
7. Each contract under subd. 1. may authorize the contractor to enter into subcontracts for the performance of any of the contractor's functions or duties under the contract. In performing any such function or duty, a subcontractor shall comply with all requirements applicable to the contractor. With the department's approval, the contractor may subcontract with any person engaged in the business of selling, maintaining, or repairing motor vehicles or of selling motor vehicle replacement or repair parts.
8. Each contract under subd. 1. shall require that, if an emissions inspection is performed by a contractor or subcontractor engaged in the business of selling, maintaining, or repairing motor vehicles or of selling motor vehicle replacement or repair parts and the inspection shows that the vehicle does not comply with applicable emission limitations, the contractor or subcontractor shall advise the vehicle owner as specified in sub. (12).
(bm) The emissions test and equipment inspection of nonexempt vehicles may be performed by the department or by persons who are not under contract with the department but who are otherwise authorized by the department to perform such testing and inspection. The department may establish methods for emissions testing and equipment inspection by the department or other authorized persons of nonexempt vehicles, in addition to testing and inspection by contractors. These methods may include the installation and operation by the department or other authorized persons of self-service inspection stations and the utilization of any technology related to emissions or data transmission with which motor vehicles may be equipped, including reading and reporting diagnostic codes stored in any on-board diagnostic system capable of monitoring all emission-related engine systems or components. The department may establish methods for emissions testing and equipment inspection specifically applicable to self-service inspection stations, which methods shall apply equally to self-service inspection stations operated by contractors under par. (am) 1m. and self-service inspection stations operated under this paragraph.
(c)
1. Notwithstanding subs. (5), (6), and (9) (d), the department of transportation may, with concurrence of the department of natural resources, grant a temporary exemption for nonexempt vehicles during any period in which the department of transportation is unable to operate an inspection and maintenance program. An exemption granted under this subdivision is valid until the next required inspection of the vehicle required under sub. (6), or until the time given by the department of transportation to complete inspection of the vehicle, whichever occurs first. Notwithstanding subs. (7) and (10m), the department of transportation may deny requests for inspection during any period in which exemptions are granted under this subdivision.
2. For purposes of ss. 341.04 (1), 341.09 (2m) (a) 1. b. and 2. and (9), and 341.65 (2) (e) 2m., an inspection under this section is not required during any period in which a temporary exemption is granted under subd. 1. For purposes of ss. 341.09 (5), 341.10 (10) (intro.), 341.26 (2m) (am), and 341.63 (1) (e), a vehicle does not require inspection under sub.
