ITEM NO.: 74-11-2 Summary of Manufacturers' 1974 Model-Year Third Quarter Assembly-Line Reports (January 1, 1974 - March 31, 1974). RECOMMENDATION Refer sample size deficiency to the Enforcement Committee. SUMMARY The Staff has reviewed the reports submitted by vehicle manufacturers concerning their third quarter production. Steady-state inspection control limits are presented in Table I for hydrocarbon and carbon monoxide emissions. The average exhaust emissions for the third quarter quality audit (CVS tests) are shown in Table II by engine family for hydrocarbons, carbon monoxide and oxides of nitrogen. The Executive Officer has already taken action concerning reporting deficiencies referred to in this report. ITEM NO.: 74-11-3 Availability of Unleaded Fuel for 1975 Model Vehicles. RECOMMENDATION None. Informational Item. SUMMARY Most 1975 model passenger vehicles sold in California will be equipped with catalytic converters and these vehicles will require unleaded fuels to protect the catalysts. This report reveals that to date the supply of unleaded fuel is not assured in low population density areas nor under fuel shortage conditions. ITEM NO.: 74-11-4 Status Report on Catalytic Device Equipped Test Fleets. RECOMMENDATION None. Informational Item. SUMMARY Three fleets of catalytic converter equipped vehicles (State operated) are currently undergoing evaluation at the Board's El Monte Laboratory. The fleets are equipped with the following three emission control systems: 1. General Motors advanced catalytic converter emission control system. 2. Ford advanced catalytic converter emission control system. 3. Universal Oil Products (UOP) retrofit catalytic converter system. The General Motors fleet consists of forty-five vehicles. Some of these have been in State service since November, 1972. Test data, including deterioration effect due to mileage accumulation up to 23,240 miles, are within the 1975 California interim standards. The Ford fleet consists of fifteen vehicles. The vehicles have completed the second series of tests conducted four months after the initial tests. The average emission values are within the 1975 Federal statutory standards. The one-hundred car UOP fleet has been under test for sixteen months. The fleet vehicles (1966 and later model year cars) are equipped with retrofit catalytic converter devices. Test data show that the emission control systems have been effective in reducing carbon monoxide and hydrocarbon emissions. The emission levels have been stabilizes since the four-month test. ITEM NO.: 74-11-5 Progress Report of Mandatory Inspection of Vehicular Emission Control Systems Mandated by SB 479. RECOMMENDATION None. Informational Item. SUMMARY Senate Bill 479 establishes a mandatory vehicle emission inspection and maintenance program to be implemented by the Department of Consumer Affairs and the Air Resources Board, with the cooperation of the Department of Motor Vehicles and the California Highway Patrol. The Bill is lengthy and somewhat complicated. The purpose of this informational report is to highlight the provisions of the Bill, give a progress report of the work being done to implement it, and discuss some of the issues that still must be studies and resolved. ITEM NO.: 74-11-6 Summary Report of the Exemptions Granted from the Prohibitions of Vehicle Code Section 27156. RECOMMENDATIONS None. Informational item. SUMMARY By authority of legislation enacted in 1966, Section 27156 was incorporated into the Vehicle Code prohibiting the operation of motor vehicles unless required emission control systems are in proper operating condition. As originally adopted, Section 27156 did not allow any alterations or modifications of these control systems. Section 27156 was subsequently amended in 1970 to allow alterations or modifications that have been found by the Air Resources Board not to reduce the effectiveness of the emission control systems. Resolution 71-2 which established criteria to evaluate alterations or modifications was adopted by the Air Resources Board. This report summarizes the Staff activities associated with Section 27156 exemption applications since the adoption of Resolution 71-2. ITEM NO.: 74-11-7 Fifth Quarterly Report on the Efforts and Progress of Manufacturers in Meeting the 1975 and 1976 Federal Statutory Vehicle Emission Standards. RECOMMENDATION Approve this report for forwarding to the Legislature. SUMMARY The Air Resources Board Staff has reviewed the vehicle manufacturers' quarterly efforts and progress reports required pursuant to Sections 39158 and 39159 of the California Health and Safety Code. The reports review the manufacturers' efforts and progress in achieving the exhaust emission goals promulgated by the Federal Clean Air Act and referred to as the Federal statutory standards. The vehicle manufacturers' reports for the period emphasized the investigation of alternatives to the conventional engine with catalytic control. The attached staff report emphasizes updates of information and does not reiterate previously reported efforts and progress whenever possible.
