(1) The department of public health and environment, motor vehicle emission control section of the air pollution control division, and the department of revenue shall develop a continuing joint program for the study of the control of motor vehicle exhaust emissions, including emissions from model year 1975 and later models. Such emission control studies shall include such investigations and evaluations of existing and available motor vehicle emission control equipment and technology and the social
problems, economic impacts, effectiveness, and costs involved in the use of such technology in motor vehicle emissions inspections and maintenance programs as they may jointly recommend.
(2) (a) The department of public health and environment, motor vehicle emission control section of the air pollution control division, shall develop a pilot program for the purpose of testing a representative sample of motor vehicles with various vehicle emission control alternatives which may include emission testing and maintenance, air pollution control tune-up, and vehicle modification alternatives as determined by the commission.
(b) Based upon the results of the pilot program and emission control studies, the commission shall develop recommendations for implementing programs of emission testing or mandatory maintenance, or both; air pollution control tune-ups; and vehicle modifications, including altitude modifications and retrofit control systems, for the control of motor vehicle emissions. Such recommendations shall include information on the costs and air pollution control effectiveness of alternate control measures and legislative and regulatory measures necessary to implement an effective program. Any program recommended shall be based upon establishing statewide minimum standards and shall include more stringent standards for motor vehicles registered in air quality control basins defined by the commission.
