ITEM Progress Report on Federal Grant to Demonstrate Technological Feasibility of Controlling Oxides of Nitrogen from Vehicular Exhausts. INTRODUCTION The Arco Chemical Company, a division of Atlantic Richfield Company, has developed an automobile exhaust recycle system which has shown to be effective in reducing oxides of nitrogen. Under a Federal demonstration grant (#68A0605D), the Air Resources Laboratory is in the process of making an extensive evaluation of the exhaust recycle system. In accordance with the terms of the grant the Air Resources Board has a contract with Arco Chemical Company for the design, fabrication and installation of the system on a fleet of state owned vehicles. ITEM Progress Report on AB 690 Exhaust Control Testing Program. Pursuant to the 1968 California legislative enactment of Assembly Bill No. 690, the Air Resources Laboratory is involved in a test program to evaluate low emission exhaust control systems. These systems will be installed on a fleet of state-owned vehicles and are required to reduce the emissions as near as is technologically feasible to one gram per mile of hydrocarbons, 15 grams per mile of carbon monoxide and 1.5 grams per mile of oxides of nitrogen. In accordance with the requirements of the bill, the Air Resources Board has negotiated a contract with George W. Cornelius, San Pedro, California and with Chromalloy American Corporation, Hawthorne, California; A revised proposal was submitted late in April by the University of California, Los Angeles and a contract is in the process of being negotiated.
