Report on Proposed Permit System Rules that Consider Ambient Air
Quality.

                          RECOMMENDATION

Informational Report.

                              SUMMARY

A task force consisting of EPA and ARB personnel has been working
on improving existing rules for implementation of new source
review requirements.  This report on the proposed new rules is
being presented to the Board for discussion and comment.  Several
air pollution control districts and EPA, Region IX, have been
invited to participate in this discussion.

ATTACHMENTS:   Discussion of Proposed Rules.
               Proposed Rules A and B plus associated
               definitions.

                        ITEM NO.:  75-16-3

Proposed Amendments to Regulations Limiting the Sulfur Content of
Unleaded Gasoline.

                          RECOMMENDATION

1.   That the Board not adopt an accelerated schedule of limits
     of sulfur content of unleaded gasoline unless air monitoring
     data or additional medical evidence indicates the need.

2.   That the Board consider a limitation of the sulfur content
     of unleaded gasoline to 200 and 100 ppm effective January 1,
     1982 and January 1, 1984, applicable in the Bay Area, San
     Diego and South Coast Air Basins.

3.   That the Board consider the adoption of the variance
     procedure given in Section IV of the staff report.

4.   That the Board consider applying the present regulation
     limiting the sulfur content of unleaded gasoline only to
     gasoline sold in the San Francisco Bay Area, San Diego and
     South Coast Air Basins and Sacramento County.

                             SUMMARY

1.   Small refiners request exemption from the sulfur-content
     regulations because of financial hardship and a claim that
     there is a general lack of need for such a regulation.  Kern
     river Local No. 1-19 of the Oil, Chemical and Atomic Workers
     International Union is concerned about possible loss of
     employment if small refiners are forced to close because of
     the sulfur and lead regulations.

2.   Some refineries would face a problem in meeting an
     accelerated schedule for the sulfur regulation.  To meet
     this difficulty, a proposed variance procedure is shown in
     the report that if adopted would permit such refiners to
     obtain enough time to build the necessary facilities. 
     However, an accelerated schedule may not be necessary unless
     indicated by new medical evidence or air monitoring data.

3.   The present sulfur regulation may not be needed outside of
     the San Francisco Bay Area, San Diego and South Coast Air
     Basins and Sacramento County because in the outside areas,
     average daily traffic volumes are less than one fifth of the
     maximum in the South Coast Air Basin.

4.   Present information indicates that a limit of the sulfur
     content of unleaded gasoline of 200 and 100 ppm, effective
     January 1, 1982 and January 1, 1984 is needed in the San
     Francisco Bay Area, San Diego and South Coast Air Basins
     only.

5.   The exemption from the regulation of small refiners in the
     South Coast Air Basin would defeat the purpose of the
     regulation.

Status Report on Standards for Abrasive Used in Abrasive Blasting
Operations.

                          RECOMMENDATION

Informational Report.

                             SUMMARY

At the June 12, 1975 meeting the Board accepted from its
Committee proposed standards for abrasives used in abrasive
blasting operations.  The Board directed the staff and the
Committee to undertake certain actions and report back prior to
the Board's consideration of adopting the proposed standards. 
This report is to advise the Board of the status of the requested
actions.

                        ITEM NO.:  75-16-6

Status Report on State Air Pollution Emergency Plan.

                          RECOMMENDATION

This is an informational report.

                              SUMMARY

Revisions to the Plan have been made to emphasize emergency
protective measures that can be taken by individuals during
periods of high air pollution and to augment abatement actions
that could be taken during an air pollution disaster.

Additional changes have been proposed and considered at a public
hearing on August 20, 1975 to meet the requirements of the
federal Clean Air Act.

Source curtailment plans for APCDs in the South Coast Air Basin
have been reviewed to estimate their effectiveness if it should
be necessary to implement these plans.  The data indicate that a
reduction in hydrocarbon emissions from stationary sources could
be as high as 50% if Stage 3 control actions are implemented.
