Staff Report to the Assembly on Recommended Standards for the
Composition of Gasoline.

The 1970 California Assembly adopted Assembly Bills Numbers 80
and 81 directing the Air Resources Board to establish maximum
standards of unsaturation for gasoline sold in the south Coast
air Basin (AB 80) and requires the State Air Resources Board to
establish, under specified conditions, maximum standards for
volatility of gasoline sold in the State of California (AB. 81).

Statement for Hearing on Lead.

The hearing on the petition of the Environmental Defense Fund
regarding an exhaust emission standard for lead and the
definition of lead is opened.

The Air Resources Board held a number of hearings on lead during
the past year.  Several of these were concerned with the effects
of lead and the need for an ambient air quality standard.  At
that time we heard about the occurrence of lead in the
environment, the sources of the lead, and the health effects. 
The Air Resources Board took all this into account when it set
the air quality standard for lead.

There is nothing to be gained by going over all this ground
again.  The purpose of today's hearing is to consider the
proposed exhaust emission standard and definition of lead.  I
urge those who testify to keep this in mind.  If not, I will have
to remind you of it.

                               ITEM

Outlook for Further Control of Hydrocarbons and Oxides of
Nitrogen.

The standard of 0.1 ppm for one hour for oxidant is fairly
stringent in light of the present air quality in the metropolitan
areas of the State.  Oxidant levels above 0.1 ppm have occurred
frequently during 1970; there were 9 days during which ozone
levels of 0.5 ppm or greater were reported by the Los Angeles
County Air Pollution Control District.

In recommending the standard for adoption, the Technical Advisory
Committee reported that this standard might not be achieved with
the present control programs.  The committee reported that to
meet the standard, emissions would need to be reduced to levels
below those now proposed, and perhaps industries and fossil-fuel
power plants would need to be made essentially emission free or
moved from the South Coast Basin.

Oxidant is a product of atmospheric reactions involving
hydrocarbons and oxides of nitrogen.  this report reviews the
present control programs in the South Coast Basin and indicates
what needs to be done in addition to the present programs in
order to further reduce the emissions of these pollutants.

Staff Report on Used Car Controls

In 1970, the Air Resources Board considered the possibility of
accreditation of exhaust control systems for the 1955-65 model
vehicles.  these devices were proposed by several companies,
including major automobile manufacturers.

A control system developed by American Pollution Controlled,
Inc., was accredited on the basis that emissions met the
standards specified in the Health and Safety Code.  A condition
of the accreditation was that 50 of the devices be supplied to
the Board for installation on state cars.  This will permit more
extensive evaluation of possible adverse effects on performance
and driveability.

The prospect of finding that devices are available for
installation on used cars at time of transfer of ownership has
been altered by the announcement in December of the withdrawal of
Norris Industries from its joint venture with American Pollution
Controlled, Inc.  Since the Board's resolution of accreditation
specified both companies as applicants, the Norris withdrawal has
the effect of negating the Board's September action accrediting
the APC device.  American Pollution controlled, Inc., has been
seeking an alternative partner with manufacturing and
distributing capability.  If successful, the new partnership
could apply for renewed accreditation of the system already
tested.

The development of the device of other companies has not reached
the point where that can be considered for accreditation by the
Board.
