during the months of March, April and May each year.
Modifications to district Agricultural Burning Implementation

The Sacramento County Air Pollution Control Board adopted a
modification to its Agricultural Burning Implementation Plan on
January 14, 1974. This modification allows the district Air
Pollution Control Officer to authorize, by permit, agricultural
burning in the northern area of the district when the wind blows
from the north if denial of such permit would threaten imminent
and substantial loss.
ITEM NO.: 74-8-4
Report on Executive Officer's Revisions to Subvention Regulations
Relating to Local Implementation Programs.
At its March 12, 1974 meeting, the Board instructed the Executive
Officer to change the Subvention Regulations to permit local
districts to have their 1974-75 and subsequent fiscal years'
subvention application deemed to fulfill the requirements of
their implementation program. As authorized by the Board, the
Executive Officer has made the necessary changes (as emergency
regulations). A letter has been sent to the districts informing
them of this change.
The Executive Officer has made additional administrative changes
to the regulations.

ITEM NO.: 74-8-5
Public Hearing - State Implementation Plan - Revision to Indirect
Source Review Procedures.
Adopt Resolution 74-22 thereby adopting the indirect source
proposal as amended on April 11, 1974, which includes the
statement of principle.
Since the November 13, 1973 Board meeting the Board has been
considering amending the State Implementation Plan to provide
procedures for the review and regulation of indirect sources.
The proposed amendments have been widely distributed for public
comment, and many changes have been made in response to these
comments. In the staff's opinion, comments received on the
February 14, 1974 proposal do not warrant further changes in the
proposal. However, the staff suggests five minor modifications
to the February 14, 1974 version.
ATTACHMENT: Summary of written comments received on the
February 14, 1974 proposal.

ITEM NO.: 74-8-6
Report on Local Permit Systems that Consider Ambient Air Quality.
None. For Information Only.
At its February 14, 1974 meeting, the Board instructed the staff
to schedule public hearings to amend the basin plans of four air
basins to include the requirement that ambient air quality
standards be considered in the review of applications for
authority to construct. It appears that it may not be necessary
to schedule such hearings because local authorities in these air
basins are taking steps to adopt the needed requirements.

Report of Investigation of Four Variances Issued or Extended by

staff to investigate variances issued to U.S. Borax Chemical
Company, Kern County, Calico Rock Milling Inc., San Bernardino
County and Stockton Elevator and Occidental Chemical Company, San
Joaquin County. Since the December Board meeting the staff has
received compliance schedules for each of these sources. All
four schedules appear reasonable and three have been approved by
EPA. The fourth schedule, Occidental Petroleum is presently
being reviewed by EPA.
ITEM NO.: 74-8-8
Report on Emissions from Rice Dryers in the Sacramento Valley Air
Refer to the Technical Committee for evaluation.
The Board, at its meeting on March 7, 1973 deferred action on a
proposal to hold a public hearing under Section 39054 to consider
revised regulations for Glenn County APCD. The Board at that
meeting instructed the staff to obtain data and report back to
the Board on particulate emissions concentrations, particle size
distributions under 10 microns from uncontrolled and controlled
rice dryers, the types of control equipment and the effectiveness
of control equipment. The staff conducted a study of emissions
from 21 rice dryers in the Sacramento Valley Air Basin during the
fall of 1973. A report on the study is attached.
