ITEM NO.: 73-17-2
Report of Staff Action to Implementation Board Decision
Concerning Re-Examination of Accredited NOx Control Devices.
RECOMMENDATION
Adopt proposed restriction of basic timing spark retard if
Board's criterion on qualifying NOx control is to be met.
SUMMARY
The attached staff report describes actions taken by the staff to
implement Resolution 73-27-C. The effect of Resolution 73-27-c
on each accredited device is discussed. Data concerning the
effect of spark retard beyond VSAD on exhaust gas temperature,
fuel consumption, and NOx reduction are presented. A staff
proposal to restrict the amount of spark retard of basic timing
is also presented.
ITEM NO.: 73-17-3
Status Report on Control of Vehicle Refueling Emissions.
RECOMMENDATION
None. This is a staff status report.
SUMMARY
Four air pollution control districts have adopted rules governing
vapor losses during service station and/or vehicle tank refueling
and an assembly bill of a similar nature has been introduced in
the legislature and recommended for approval by the staff. A
number of systems have been built in these districts and several
studies instituted in order to explore cost-effectiveness and
feasibility of vapor recovery systems. This report describes the
legislation, engineering systems and the various efforts and
studies to control organic vapors during the refueling process.
ITEM NO.: 73-17-4
Status Report on Atmospheric Studies. The 1973 Los Angeles
Reactive Pollution Study.
RECOMMENDATION
None. This is an information report.
INTRODUCTION
In 1968-69 the Atmospheric Studies Section of the Air Resources
Board participated with the Coordinating Research Council
Measurements of Atmospheric Pollutants in Urban Areas Project
Group (CRC-CAPA-7) in conducting several studies of the Los
Angeles atmosphere. These studies indicated a need for an
effective computer model of the atmosphere which gives realistic
and practical answers to pressing questions of control strategy
alternatives as well as choices for urban planning and
development. The model would not be an end in itself but should
be regarded as one of the tools to be used in making decisions
affecting future air quality on an urban and regional scale.
ITEM NO.: 73-17-6
Legislation.
SUMMARY
This is a status report on air pollution control legislation.
About 115 bills dealing directly or indirectly with air pollution
have been introduced. The important bills are summarized below,
as they stood on June 29, the beginning of the Legislature's July
recess.
RECOMMENDATION
None.
