The Air Resources Board's regulations began with the organization and provisions developed by the Motor Vehicle Pollution Control Board. The Air Resources Board has, since its first days, received several additional statutory obligations and has developed new regulations in carrying them out, and the Motor Vehicle Pollution Control Board's system has proven unsatisfactory to handle them. This system, among other things, divorces standards from test procedures and has a separate article devoted to oxides of nitrogen, resulting in the duplication of the printing of most current test procedures. Also, standards and test procedures for new 1971 and earlier model vehicles no longer serve a useful purpose and should be deleted. Finally, some provisions from crankcase and fuel evaporative control devices have been deleted because of federal preemption. The following revision to Title 13 eliminates the duplication and the obsolete standards and test procedures, and reorganizes the remaining material in a clear and meaningful manner. Adoption of Resolution 72-91 is recommended by the staff. ITEM Proposed Criteria for the Evaluation of Motor Vehicle Pollution Control Devices and Fuel Additives. Section 39052.7 of the Health and Safety Code (enacted during the 1971 Legislative Session) requires the Air Resources Board to establish criteria for the evaluation of motor vehicle pollution control devices and fuel additives. The staff drafted proposed criteria which were presented to the Board at its May 17, 1972 meeting. The Board, in response to this, requested the staff to prepare these regulations for adoption into Title 13 by scheduling a public hearing to be held on June 21, 1972. Accordingly, a notice of proposed changes in the regulations of the Air Resources Board pertaining to these criteria was published on May 18, 1972. The staff recommends that the Board approve the attached regulations by adopting the accompanying resolution. ITEM Effects of Vacuum Spark Advance Disconnection on Exhaust Valve Life. The Board has received several applications from manufacturers for accreditation of retrofit devices to be installed on 1966-1970 model year vehicles to reduce the emission of oxides of nitrogen. Some of these devices incorporate vacuum spark advance disconnect (VSAD). Although emission test data for systems utilizing VSAD indicate substantial reduction in oxides of nitrogen, questions concerning the nature and extent of adverse effects are presently unresolved. Specifically, the issue of potential decrease in exhaust valve life due to increased temperature exposure has recently been stressed. The Board staff accepts as fact that, qualitatively, VSAD will tend to decrease exhaust valve life. However, data necessary to make a judgement as to the quantitative extent of this effect is lacking. ITEM Application for Accreditation of a Motor Vehicle Exhaust Emission Control Device for Oxides of Nitrogen. INTRODUCTION This report is a staff evaluation of the Echlin Corporation oxides of nitrogen control device for used vehicles (1966-1970 year models). The basis for evaluation and specific requirements are stated in the California Health and Safety Code, Section 39107.6 and 39175 to 39184, and Title 13 of the California Administrative Code, Chapter 3, Subchapter 2, Article 3. Test details and specific requirements are contained in the "California Oxides of Nitrogen Control Device Test Procedures for used 1966 through 1970 Model Year Vehicles Under 6,001 Pounds Gross Vehicle Weight" adopted by the Board on November 17, 1971. The Oxides of Nitrogen Standards were adopted by the Board on February 16, 1972. ITEM Perfect Circle Division, Dana Corporation Application for Accreditation of a Used Motor Vehicle Exhaust Emission Control Device for Oxides of Nitrogen. INTRODUCTION This report is a staff evaluation of the Perfect Circle Division of Dana Corporation exhaust emission control device for reduction of oxides of nitrogen emission from used light duty 1966 through 1970 model year motor vehicles. The basis for evaluation and specific requirements are stated in the California Health and Safety Code, Sections 39107.6, 39177.1, 39177.2, 39177.3, and 39177.4, and Title 13 of the California Administrative Code, Chapter 3, Subchapter 2, Sections 1948 and 2208(f). Test details and specific requirements are presented in the "California Oxides of Nitrogen Control Device Test Procedures for Used 1966 through 1970 Model-Year Motor Vehicles under 6,001 Pounds Gross Vehicle Weight" as adopted by the Board on November 17, 1971, with device standards adopted on February 16, 1972. ITEM Public Hearing on Proposed Agricultural Burning Guidelines and Meteorological Criteria. INTRODUCTION At the April 19, 1972 Board meeting, the staff reported to the board on the Proposed New Agricultural Burning Guidelines and Proposed Meteorological Criteria. The Board directed the staff to publish a notice and hold public hearings at three locations in the State. Such notice was given and more than 1500 copies of the proposed guidelines and criteria were mailed to interested persons. The first hearing, held in Santa Barbara on May 26, 1972, had about 35 people in attendance. The second hearing, held May 31, 1972 in Indio, had about 50 people in attendance. Both of these hearings were chaired by Mr. Walter Schmid. The third hearing will be held in Eureka on June 19, 1972. This booklet contains the material pertinent for the public hearing on the proposed Agricultural Burning Guidelines and Meteorological Criteria - Item 7 in the Agenda of the Board meeting on June 21, 1972.
