ITEM Status Report on Used Car Devices. This report presents in summary form information on a number of devices which have been or may be offered to the Board for accreditation. The basic laws and test procedures make a distinction between used cars 1965 model and older and cars of model year 1966 through 1970. Although a number of the devices are applicable to both categories with some modifications, the two age classes will be considered separately in this report. ITEM Application for Accreditation for an Exhaust Emission Control Device for Used Vehicles. INTRODUCTION At the December 15, 1971 Board Meeting, General Motors' application for accreditation of a used car exhaust emission control device for 1955 and 1965 model year vehicles was referred to the staff for additional study. The Board had indicated that additional test data and information was needed concerning the question of adverse driveability effects. Fuel consumption with and without the General Motors device was also measured. The application General Motors had submitted was for the accreditation of a device to control hydrocarbons and oxides of nitrogen for classes B, C, D, E, and F vehicles. This report summarizes the additional information and test data supplied by General Motors and the Air Resources Board Laboratory. The December 15, 1971, Staff Report is included for reference purposes. ITEM Proposed Standards for Oxides of Nitrogen Control Device (Exhaust Emissions Test Procedures for Oxides of Nitrogen for 1966-70 Models). INTRODUCTION This report presents a recommended standard for devices designed to control oxides of nitrogen from 1966 through 1970 model year vehicles. Senate Bill 578 was enacted by the legislature and signed by the Governor in November 1971. This legislation requires the Board to set standards for devices to significantly reduce emissions of oxides of nitrogen from the exhaust of 1966 through 1970 model year motor vehicles. The bill also sets the maximum retail price of the device at thirty-five dollars ($35) installed. ITEM Staff Report on Applications from Cities and Counties to Continue Open Burning on Waste Disposal Sites. INTRODUCTION As of the December 15, 1971 meeting, the Air Resources Board approved time extensions to use open fires for the purpose of disposal of solid waste for 263 city or county disposal sites. Thirty-one additional requests for time extensions have been received and evaluated. In addition, the Board has received on request for transfer of the extension granted to one site to another site within the county. The 31 requests for time extension and the request for transfer of burning variance are approvable. As requested by the Board during the December meeting, the staff also investigated problems with the Madera County, the Willits and the Meadow Lake dump sites. ITEM Staff Report on the Status of Agricultural Burning Implementation Plans. Thirty-one of the thirty-three Agricultural Burning Implementation Plans from county air pollution control districts that were required to submit such a plan have been approved by the Board. The plans of Los Angeles and Riverside Counties were still pending after the December 15, 1971 Board meeting. The staff is recommending the approval of the Los Angeles plan, the temporary approval of the Riverside plan and approval of a request from the Yolo-Solano Unified Air Pollution Control District to add to its list of burning permit issuing agencies.
