ITEM NO.: 75-1-2 Public Hearing Regarding Proposed Changes to the Highway and Mandatory Inspection Exhaust Emission Standards. RECOMMENDATION Adopt Resolution 75-2. SUMMARY The staff has reviewed its surveillance data and has verified the California Highway Patrol's findings that 1966-67 Volkswagens would be expected to fail the 1966-1970 idle exhaust emission standards for the highway and mandatory inspection programs by a higher than average rate. The staff thus proposes new standards to correct this inequity. In the attached staff report, Executive Officer authority is requested to exempt vehicles which have tune-up specifications incompatible with the highway and idle mandatory inspection standards. The staff further proposes that Section 2176, title 13 of the California Administrative Code be amended so that there is clear differentiation between the hydrocarbon and carbon monoxide standards which may not be exceeded and the NOx standards which serve only as a screening test for malfunctioning NOx control systems. A rotary engine classification and minor language changes are also discussed. ITEM NO.: 75-1-3 Proposed Emergency Action Regarding Exemption of Heavy-Duty Diesel-Powered Vehicles from Certificate of Compliance Requirements. RECOMMENDATION Adopt Resolution 73-8-B. SUMMARY Subsection 4000.1(b) of the Vehicle Code authorizes the Air Resources Board to exempt designated classes of motor vehicles from the requirement that certificates of compliance be obtained to complete initial registration and transfer of ownership. For the past two years, 1973 and 1974, the Board has exempted heavy-duty Diesel-powered vehicles from this requirement. Though the staff has been working cooperatively with the Interagency Committee to implement this program at the official motor vehicle pollution control stations, this program will not be implemented until January, 1976. Under the circumstances, the staff recommends the exemption be extended through 1975. Since the exemption expired December 31, 1974, the staff also recommends that this exemption be extended by emergency regulation to be effective immediately upon filing with the Secretary of State and that the Executive Officer initiate proceedings to confirm this action within the required 120 days. ITEM NO.: 75-1-4 Consideration of Air Quality Products' Application for Accreditation of its Pure Power-Electro-NOx Control Device for 1966-70 Class (d, e and f) Vehicles. RECOMMENDATION Adopt Resolution 75-3. SUMMARY Air Quality Products has submitted an application for accreditation of its Pure Power-Electro-NOx device as an NOx control device. The application is intended for class (a) through (f) 1966-70 model-year vehicles. However, at the time of this report writing, the applicant had not completed the accreditation testing of all classes of vehicles. At the applicant's request, the evaluation of classes (d, e and f) vehicles is being presented at this time. The Pure Power-Electro-NOx device is a vacuum spark advance disconnect (VSAD) device. VSAD is accomplished by an adjustable engine vacuum from reaching the distributor vacuum advance mechanism at speeds up to 57 mph. Confirmatory tests by the Air Resources Board Laboratory show that the device satisfies the 42% NOx reduction standard and is effective at 55 mph. It is the staff's opinion that the criteria of the NOx control device test procedures have been satisfied; the staff recommends accreditation. ITEM NO.: 75-1-5 Summary of New 1975 Model-Year Vehicle and Engine Approvals. RECOMMENDATION Information item. SUMMARY This report presents tables listing 1975 model-year vehicles and engines approved by the Air Resources Board for sale in California as of December 19, 1974. The certification emission test results for all vehicles and engines tested are also listed. This report is published in partial fulfillment of the requirements of Section 39052(j) of the Health and Safety Code.
