Decentralized emissions program for inspections, when, program for inspecting certain motor vehicles, requirements--application for authorization to conduct emission inspections--repairs--certification to begin, when, report--remote sensing devices and gas cap tests authorized--program requirements, interagency agreements--rulemaking authority--promotion of program.

643.303. 1. Beginning September 1, 2007, emissions inspections required by sections 643.300 to 643.355 shall be conducted through a decentralized emissions program that meets the requirements of this section. Prior to September 1, 2007, the air conservation commission shall develop a decentralized emissions inspection program that allows official inspection stations to conduct on-board diagnostic emission inspections of 1996 model year and newer motor vehicles equipped with on-board diagnostic systems meeting the federal Environmental Protection Agency On-Board Diagnostics II (OBDII) standards. The decentralized emissions inspection program shall, at a minimum, provide for the following:

(1) The periodic inspection of certain motor vehicles as required under section 643.315;

(2) The certification and operation of official emissions inspection stations and the licensing of emission inspectors;

(3) The testing of motor vehicles through on-board diagnostic testing technologies;

(4) The training, certification, and supervision of emission inspectors and other personnel; and

(5) Procedures for certifying test results and for reporting and maintaining relevant data records.

2. In addition to any other criteria established by the commission under section 643.320 or by rule, the decentralized emissions inspection program shall allow any official inspection station located in an area described in subsection 1 of section 643.305 otherwise qualified by the Missouri state highway patrol to conduct motor vehicle safety inspections under section 307.360 to conduct on-board diagnostic emission inspections. Any motor vehicle safety inspection station that desires to conduct emissions inspections shall submit an application for a certificate of authorization to the commission as provided for under section 643.320. Other individuals, corporations, or entities that do not conduct motor vehicle safety inspections may conduct emission inspections provided they meet the qualifications set forth in sections 643.300 to 643.355 and the rules promulgated by the commission. Applications shall be made upon a form designated by the commission and shall contain such information as may be required by the commission. A certificate of authorization issued under section 643.320 to conduct emission inspections shall be issued only after the commission has made a determination that the applicant's proposed inspection station will be properly equipped, has the necessary licensed emission inspectors to conduct inspections, and meets all other requirements of sections 643.300 to 643.355 or rules promulgated to carry out the provisions of those sections.

3. The decentralized emissions inspection program shall allow any official inspection station that is certified to conduct an on-board diagnostic emission inspection under sections 643.300 to 643.355 to repair motor vehicles in order to bring such vehicles into compliance with sections 643.300 to 643.355, if such station and personnel meet the qualifications to conduct emission repairs as set forth in sections 643.300 to 643.355. An official emission inspection station may elect to be an emissions test-only station or may elect to conduct both emission inspections and repairs.

4. The commission is authorized to begin certification of official inspection stations prior to September 1, 2007, in order to implement the decentralized emissions inspection program. Prior to January 1, 2007, the department of natural resources shall issue a report to the general assembly and the governor regarding the progress of implementing the decentralized emissions inspection program. The report shall include, but not be limited to, a summary describing how many inspection stations or individuals the department expects to participate in the program and how many inspection stations or individuals will be qualified by September 1, 2007, to conduct such emissions inspections.

5. The commission may, as a part of implementing the decentralized emissions inspection program, use remote sensing devices to collect information regarding the vehicle fleet emissions characteristics and registration compliance within the area described in subsection 1 of section 643.305. The decentralized emissions inspection program established by the commission may also include a clean screen program that utilizes remote sensing devices. Owners of eligible vehicles who comply with clean screen/remote sensing procedures shall be deemed to have complied with the mandatory inspection requirements for the next inspection cycle. As used in this subsection, the term "clean screen program" shall mean a procedure or system that utilizes remote sensing technologies to determine whether a motor vehicle has acceptable emission levels and then allows the motor vehicle owner to bypass the emissions inspection test required under section 643.315.

6. The decentralized emissions inspection program may include a gas cap pressure test and a visual inspection component, and such tests may be included as part of the motor vehicle safety inspection test under section 307.350.

7. As used in sections 643.300 to 643.355, "decentralized emissions inspection program" means an emissions inspection program under which a certified emissions inspector conducts emissions inspection testing at an official inspection station.

8. The decentralized emission inspection program shall satisfy the requirements established by regulation of the United States Environmental Protection Agency.

9. The decentralized emissions inspection program established by the commission and sections 643.300 to 643.355 shall not be construed to be a new program as described in section 23.253, and the decentralized emissions inspection program shall not be subject to the sunset mandate prescribed by sections 23.250 to 23.298.

10. No later than July 1, 2007, the department of natural resources and the Missouri highway patrol shall enter into an interagency agreement covering all aspects of the administration and enforcement of sections 643.300 to 643.355.

11. No later than July 1, 2007, the air conservation commission shall promulgate rules for the implementation of this section. Any rule or portion of a rule, as that term is defined in section 536.010, that is created under the authority delegated in this section shall become effective only if it complies with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028. This section and chapter 536 are nonseverable and if any of the powers vested with the general assembly under chapter 536 to review, to delay the effective date, or to disapprove and annul a rule are subsequently held unconstitutional, then the grant of rulemaking authority and any rule proposed or adopted after August 28, 2006, shall be invalid and void.

12. Prior to September 1, 2007, the department of natural resources shall actively promote participation in the decentralized emissions inspection program among qualified motor vehicle dealers, service stations, and other individuals. After the implementation of the decentralized emission inspection program, the department shall monitor participation in such program. In determining whether there are a sufficient number of individuals conducting motor vehicle emission inspections under the decentralized program, the department shall attempt to ensure, through promotional efforts, that no more than twenty percent of all persons residing in the affected nonattainment area reside farther than five miles from the nearest inspection station.
