Progress Report on Federal Grant to Demonstrate Technological
Feasibility of Controlling Oxides of Nitrogen from Vehicular


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.


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.
