ITEM Manufacturer's Response Concerning Assembly-Line Test Results for the First Quarter's Production of 1973 Model Year Vehicles. RECOMMENDATION Manufacturers who have exceeded the quality audit failure rate and have not responded to the Executive Officer's request should be asked to appear before the Board for a discussion of remedial measures taken by them. SUMMARY On December 20, 1972, the Board considered a staff report concerning the manufacturers' assembly-line test results for the first calendar quarter of production of 1973 model year vehicles. The Executive Officer has requested manufacturers to submit a plan of action to correct a number of discrepancies that had been reported at the time this report was prepared. None of the manufacturer's responses had been received. The lack of response can possibly be attributed to the fact that most manufacturers offices were closed during the Christmas holidays. This matter is being considered today at the request of the Board. The staff report of December 20, 1972, was recently revised to include the late submissions. Tables I, II, III, and IV of the revised report are attached. As of the date this report was prepared, none of the manufacturers had responded to the Executive Officer's request. ITEM Dana Corporation Request for Approval to Modify its Presently Accredited NOx Control System for 1966-1970 Model Year Vehicles. RECOMMENDATION Approve Dana Corporation request to modify its Retronox system for the specified vehicles. SUMMARY Dana Corporation has requested permission to modify its accredited Retronox system by replacing the electronic speed switch with a vacuum delay valve on vehicles with ported spark carburetors. The reason stated by Dana for the modification was to simplify the installation and to lower the cost. The system as now accredited will continue to be used for vehicles that use the intake manifold as the vacuum source. Emission, driveability and fuel economy test data have been submitted to verify the manufacturer's claim that the modification will not degrade the exhaust emission control effectiveness or adversely affect vehicle performance. ITEM Summary of 1973 Model Year New Vehicle and Engine Approvals. RECOMMENDATION For informational use only. SUMMARY This report presents tables listing 1973 model year vehicles and engines approved for sale in California by the Air Resources Board with exhaust emission results based on approval fleet tests. Such a report is required to be published by Section 39052(j) of the Health and Safety Code. ITEM Follow-up on Investigation of Incorrect Installation of Used Car Exhaust Emission Control Devices. RECOMMENDATION Request the Department of Consumer Affairs to submit periodic reports on action taken to assure compliance with the installation instructions of all used car emission control devices. SUMMARY On November 21, 1972, the Board received a report from the Department of Consumer Affairs and the ARB staff concerning improper installation of used car exhaust emission control devices. The report disclosed that of 24 installations checked, one or more deficiencies were found in 22 of them. Mr. Robert Alexander, Chief of the bureau of Automotive Repair, Department of Consumer Affairs, reported that action would be taken against those stations that did not comply with the installation instructions; however, it would take approximately 60 days to complete this actions. He has been invited to report to the Board the action taken by the Department of Consumer Affairs. ITEM Exemptions of 1966-70 Model Year Vehicles from Required Oxides of Nitrogen Exhaust Emission Control Devices. RECOMMENDATION For informational use only. SUMMARY The attached Executive Order (G-19) issued January 8, 1973, lists the 1966 thru 1970 vehicles exempted from the installation of an accredited oxides of nitrogen exhaust emission control device. The Executive Order is the same as considered by the Board at the December 20, 1972 meeting except as modified to reflect the accreditation of the STP device.
