ITEM Installation Schedule Deferral 1966-1970 NOx Devices. Senate Bill No. 578 includes the following with respect to installation scheduling: Vehicle Code Section 4602, (b) The department shall require, upon 1973 renewal of registration of any motor vehicle subject to Section 39177.1 of the Health and Safety Code, a valid Certificate of Compliance from a licensed motor vehicle pollution control device installation and inspection station indicating that such vehicle pollution control device which is in proper operating condition and which is of a type that has been accredited by the State Air Resources Board pursuant to Section 39177.1 of the Health and Safety Code. For extraordinary and compelling reasons only, the State Air Resources Board may, by regulation, after a public hearing, defer or delete the requirement of Certificates of Compliance required pursuant to this subdivision. In such event, the Board may adjust the schedule of installation adopted pursuant to subdivision (a) of Section 39177.1 of the Health and Safety Code and shall immediately report to the Governor and the Legislature the actions taken and the reasons therefor. Since the Board only recently accredited the required devices, information received by the staff suggests that it is not practical to have devices installed on all 1966-70 model vehicles by February of 1973. For this reason the Executive Officer has requested testimony from organizations most affected by this program. ITEM Report of Inter-Agency Enforcement Committee Meeting. On September 22 a meeting of the newly reconstituted committee was held in Sacramento. Members John McLaughlin, Department of Motor Vehicles, John Drobney, Department of Consumer Affairs, and G.C. Hass, Air Resources Board, were present. Inspector D.L. Gibson, California Highway Patrol, was represented by Captain William Fradenburg. Mr. Romney and other agency staff members were also present. The committee considered the need for deferral of the February, 1973, completion date and concluded it would be physically impossible to meet the deadline in the time remaining. The next annual registration date, February, 1974, would require an average of over two installations per day per licensed installation station, if all chose to market the devices. Each installation is estimated to require about 3/4 hours. While this task would take a sizeable portions of the stations' time, it could be accomplished if the workload were well distributed. ITEM Summary of Experience with 1955-1965 Exhaust Emission Control Device Retrofit Program. At the July 12 meeting, the Board instructed the staff to keep it informed of citizen complaints concerning the exhaust emission control device retrofit program for used cars. This report includes these complaints and presents a summary of the staff's experience to date with this program. ITEM Device Installation Schedule for 1955-1965 Vehicles. A recommendation was made at the August 25, 1972 Board meeting by the Department of Motor Vehicles to begin installation of the 1955-65 retrofit devices after the peak registration period of December 1, 1972 to February 9, 1973. During this time period the total registration is estimated to be approximately 13.4 million vehicles. The introduction of a new program of retrofit devices may impose an extra burden on this peak-load operation. ITEM Summary of Executive Orders Issued in Accordance with Resolution 72-104. On July 19, 1972, the Board adopted Resolution 72-104 which defined those official actions which could be taken by the Executive Officer without formal Board action. The Board requested the Executive Officer to keep it informed of approvals granted. This report is a summary of new car approvals that had been granted as of September 1. ITEM Assembly Line Testing and Enforcement of New Vehicle Standards. The Air Resources Board's (ARB) program of confirmatory testing of vehicles at the end of the assembly line has been in effect since February, 1972. As with all new equipment put on-line for the first time, testing was slow at the beginning. As reported to the Board at its May 17, 1972 meeting, over 300 vehicles were tested by the hot 7-mode test during the period February-April 1972. Since then, from May-August, 1972, over 1,000 vehicles have been tested. These tests showed some engine families had high emissions as compared to the 1972 assembly line exhaust emission standards. Because of this, three vehicles from each of these engine families were selected at random for testing by the approval test procedure according to enforcement and surveillance regulations as stated in Title 13 of the Administrative Code, Section 2803. This report summarizes action taken by the staff since its last report, to assure compliance with the assembly line test procedures. ITEM Pilot Study Phase of C.H.P. Roadside Emission Tests. A pilot study of roadside idle inspection for hydrocarbons and carbon monoxide exhaust concentration has been completed by the California Highway Patrol. Idle emission standards have been set by the Air Resources Board (ARB) based on data from ARB surveillance studies. Idle standards were set for eleven categories of vehicles based on vehicle model year, foreign or domestic, and type of emission control system (engine modification or air injection). One of the purposes of the pilot study was to obtain data on a larger scale and to evaluate rejection rates for each of the eleven categories and the two contaminants. ITEM Ad-Hoc Medical Advisory Committee. BACKGROUND At its September 12, 1972 meeting, the Board requested the California Department of Public Health ro recommend membership on an Ad-Hoc Medical Advisory Committee to assist the Board in the development of emergency episode criteria. This committee is to br composed of members of the following organizations: State Department of Public Health, California Medical Association, California Thoracic Society, California Heart Association, Tuberculosis & Respiratory Disease Association, and California medical schools, both public and private. DISCUSSION The Department of Public Health has responded with the attached memorandum and proposed recommended membership for the Ad-Hoc Medical Advisory Committee. The California Heart Association has been contacted but has not furnished the Department of Public Health with a recommendation. In absence of such a recommendation, the Department of Public Health would like to recommend Dr. Jack Hackney for this position. This completes the Department's recommendations for the committee. The staff has discussed with the Department of Public Health a proposed charge to the Ad-Hoc Medical Advisory Committee. The proposed charge is attached.
