ITEM NO.: 73-8-2a Staff report on comparative effects of NOx retrofit devices. RECOMMENDATION Information item only. SUMMARY As requested by the Board, this report presents a staff evaluation of the effects of seven NOx retrofit devices. The report discusses NOx emissions, exhaust gas temperature, coolant overheating, and fuel consumption. ITEM NO.: 73-8-2b Report of Emissions and control Committee on the Applications of Contignitron and Carco for Accreditation of their NOx Retrofit Control Devices. RECOMMENDATION The two devices be conditionally accredited. SUMMARY Report of findings from a review of the applications of the Contignitron and Carco using criteria applied to the four NOx devices previously accredited. ITEM NO.: 73-8-2c1 Contignitron Company's Application for Accreditation of an NOx Control Device for 1966-70 Model Year Vehicles. RECOMMENDATION Deny Accreditation. SUMMARY At its March 21, 1973 meeting, the Board considered Contignitron Company's application for accreditation of its device for NOx exhaust emission control for 1966 through 1970 model year vehicles in engine size classes a, c, d, e, and f. The Board deferred action on the application and referred it to the Emissions and Control Committee for review and recommendation. The applicant has submitted data verifying compliance with the oxides of nitrogen emission reduction standard of 41.6 percent. Although the applicant has also submitted data showing compliance with the general standards except for the adverse effects criterion, the staff has reservations concerning his financial responsibility, and his capability to adequately meet the requirements for training, franchising and servicing a state-wide program. If it is the Board's decision to grant accreditation of Contignitron's device, a proposed resolution is attached to the staff report. ITEM NO.: 73-8-2c2 Clean air Research Company, Inc. Application for Accreditation of an NOx Control Device for 1966-1970 Model Year Vehicles. RECOMMENDATION Deny accreditation. SUMMARY At its March 21, 1973 meeting, the board considered Clean air Research Company's application for accreditation of its device for NOx exhaust emission control for 1966 through 1970 model year vehicles in engine size classes b, c, d, e, and f. The Board deferred action on the application and referred it to the Emissions and Control Committee for review and recommendation. The applicant has submitted data verifying compliance with the oxides of nitrogen emission reduction standard of 41.6 percent. Although the applicant has also submitted data showing compliance with the general standards except for the adverse effects criterion, the staff has reservations concerning his financial responsibility, and his capability to adequately meet the requirements for training, franchising and servicing a state-wide program. If it is the Board's decision to grant accreditation of the CARCO device, a proposed resolution is attached to the staff report. ITEM NO.: 73-8-3 Proposed Exemptions of Class (a) 1966-70 Model Year Vehicles from Required NOx Controls. RECOMMENDATION Comment on the proposed Executive Order listing the general vehicle exemptions. SUMMARY The Air Resources Board has recently accredited an NOx control device for Class (a), 140 CID or less, vehicles. The blanket exemption from the NOx retrofit program for these vehicles is removed by the proposed Executive Order, G-19-2. Information was sought from the manufacturers concerning exemptions for class (a) vehicles for other reasons, and the information received to date is summarized. Also included are revisions to the previous exemption list to clarify and make more specific certain exemption categories. The proposed changes to Executive Order G-19-1 are set forth in italics. ITEM NO.: 73-8-5 Consideration of Proposed Exhaust Emission Standards and Test Procedures for 1975 and Subsequent Model Gasoline Powered Motor Vehicles under 6,001 Pounds Gross Vehicle Weight. RECOMMENDATION None. (A public hearing concerning these procedures will be held at a future Board meeting.) SUMMARY In order to make the California approval test procedure compatible with the Federal certification procedure for New Motor Vehicles, the format for the California procedure is being changed to identify the unique California requirements as stated in the Health and Safety Code and Title 13 of the California Administrative Code in addition to the applicable Federal Regulations. The format contained herein makes maximum use of the Environmental Protection Agency procedures by reference to the applicable Federal Register Vol. 37 No. 221, dated November 15, 1972 and for subsequent revisions which may be adopted. These procedures are applicable to exhaust emissions from new light-duty vehicles first sold and registered in the State of California. Where specific differences exist between the Federal and California requirements, the California regulations are stated. The requirements for crankcase and evaporative controls for new vehicle approval have been pre-empted by the Environmental Protection Agency. ITEM NO.: 73-8-6 Proposed restriction on certification of crankcase emissions control devices. RECOMMENDATION Hold a public hearing on proposed changes. SUMMARY Positive crankcase ventilation (PCV) valves on late model vehicles have flow characteristics which may be critical to the exhaust emission control system. The proposed restriction will limit the certification of replacement crankcase devices to 1967 and earlier vehicles. The operative standard for post-1967 vehicles will be the original equipment design, as is the case with other replacement parts. ITEM NO.: 73-8-7 Report of Emissions and Control Committee on investigation of effect of fuel surfactant additives on emissions. RECOMMENDATION No immediate action. Review situation in 1974. SUMMARY Report of findings from two meetings with gasoline and automobile manufacturers. ITEM NO.: 73-8-8a Gas Turbine Peaking Units at the Glenarm Plant of the City of Pasadena. RECOMMENDATION None. This is an informational report. SUMMARY The attached report is submitted in response to the Board's request at the April 4 meeting, and provides updated information on the status of the power plant proposed for construction by the City of Pasadena. ITEM NO.: 73-8-8b Research Contracts. RECOMMENDATION Adoption of Resolution 73-19 and 73-20. SUMMARY Research projects recommended by the Research Proposal Screening Committee. ITEM NO.: 73-8-8c Report of Implementation Plans and Compliance Committee on review of deficiencies noted in staff report presented to the Board at its March 21, 1973 Meeting on "Assembly-Line Test Results for the 2nd Quarter Production of 1973 Model Year Vehicles." RECOMMENDATION No further action at this time. SUMMARY The Implementation Plans and Compliance Committee met on April 10, 1973 at the Air Resources Board Laboratory to review the deficiencies noted in the results of the 2nd quarter reports of assembly-line tests of 1973 model year vehicles. The committee reviewed the letters sent to manufacturers noting these deficiencies. Most manufacturers noted what steps they were taking to correct these deficiencies. The staff is waiting for a reply from these manufacturers. Certain deficiencies noted were the results of some misunderstanding and misinterpretation of the assembly-line test procedures which have since been clarified by the latest revisions. Most other deficiencies were resolved by agreements reached with the various manufacturers.
