The proposed procedures were considered by the Board at its meeting on November 19, 1969, when only one question was raised on the procedures. Mr. Charles Heinen of the Chrysler Corporation felt that the procedures should not require the control system be suitable for all or most classes of vehicles. He felt that his company should be able to obtain accreditation of a system that applied only to used Chrysler cars. The Air Resources Board's staff pointed out that if only Chrysler developed a system, most owners of cars would not be required to have used car control, but Chrysler owners would. The Board continued the hearing until January 21, 1970, and asked the staff and Mr. Jan Stevens of the Attorney General's office to prepare statements on this issue. ITEM Report on Surveillance of Exhaust Control Systems. INTRODUCTION The Air Resources Board has conducted a surveillance test program since early in the 1966 automobile model year. This testing has been done to evaluate the performance of the control systems in use by the public and to assess the effectiveness of the motor vehicle emission program. Under California law, most 1966 and later model year vehicles are required to have systems which reduce the hydrocarbons and carbon monoxide emitted from the exhaust. These control systems are certified by the Air Resources Board when it finds that the emission standards for hydrocarbons and carbon monoxide are met. Because the certification must be issued before production of the new models begins, it is necessary to base the certification on data derived from testing pre-production vehicles. The surveillance program therefore, performs the additional function of determining how the emissions from cars in private use differ from those of the pre-production models. A report of this program was given to the Board at its January 1969 meeting. since that report 3514 additional vehicles have been tested in this program and oxides of nitrogen emissions are obtained in a routine manner. ITEM Automotive Performance, Inc. "Mark II" Crankcase Emission Control System. INTRODUCTION This report presents the evaluation of the Automotive Performance, Inc. "Mark II" closed crankcase emission control system by the staff of the Air Resources Board. The bases of evaluation are the requirements set forth in title 13 of the California Administrative Code, Chapter 3, Subchapter 1, Sections 2000 to 2004. Since approval is sought for used car installations, the report deals with both the California Crankcase Emission Standard and compliance with the Board criteria.
