ITEM NO.: 74-16-2

Continuation of Public Hearing Concerning an Amendment to the
North Coast Air Basin Coordinated Basinwide Air Pollution Control
Plan - Regulation for the Review of New and Modified Sources.

RECOMMENDATION

Adopt Resolution 74-35, thereby amending the North Coast Air
Basin Coordinated Basinwide Air Pollution Control Plan as shown
in the attachment to the Resolution.

SUMMARY

At the June 13, 1974 meeting the Board started a public hearing
to consider amending the North Coast Air Basin Coordinated
Basinwide Air Pollution Control Plan to include a requirement
that ambient air quality standards be considered by the Basin's
air pollution control districts in reviewing applications to
construct.

Because Northern Sonoma County APCD, the only district in this
air basin that had not adopted such a regulation, had already
issued a notice to conduct a public hearing to adopt necessary
changes to its permit-to-construct rules, the Board deferred the
public hearing for 60 days. The District held a hearing on July
8, 1974, but the proposed changes to the District's rules and
regulations were not adopted. The Board's hearing which was
started on June 13, should, therefore, be continued at this
meeting.

ITEM NO.: 74-16-3

Public Hearing Concerning Proposed Air Pollution Standards for
Sandblasting Operations.

RECOMMENDATION

Approve Resolution 74-44 which will adopt into Title 17 of the
California Administrative Code statewide air pollution standards
for abrasive blasting operations. The proposed standards are
attached to the resolution as Exhibit "A".

SUMMARY

Section 39079.6 of the Health and Safety Code directed the
Chairman of the State Air Resources Board to convene a Committee
of 11 members to recommend to the Board for adoption not later
than January 1, 1975, air pollution standards for sandblasting
operations. The Committee met and recommended air pollution
standards for abrasive blasting operations to the Board for
adoption at the June 15, 1974 Board meeting. At that time, the
Board received comments indicating that many interested parties
did not receive the proposed standards in time for extensive
review. The Board scheduled another public hearing for August
15, 1974 and directed the staff to issue a notice 30 days in
advance of the hearing. The Board also directed the Committee to
provide an opportunity for interested parties to present their
views, and to incorporate in its recommendations whatever
comments it deems appropriate. A notice for this public hearing
was issued on July 3, 1974. Section 39079.6 of the Health and
Safety Code requires the Board to adopt air pollution standards
for sandblasting operations based upon the recommendation of the
Committee.

ITEM NO.: 74-16-4

Report on District Implementation Programs.

RECOMMENDATION

This is an informational report.

SUMMARY

Section 39275 of the Health and Safety Code requires California's
air pollution control districts to submit to the Air Resources
Board a program to implement their respective air basin air
pollution control implementation plans. On March 12, 1974 the
Board directed that all districts are required to submit an
implementation program by July 1, 1974 whether or not they apply
for subvention and that submittal of an approvable program is
prerequisite to receiving subvention in fiscal year 1974-75. On
March 27, 1974 the Administrative Code was amended by the
Executive Officer to allow the districts the option of using
their subvention application as their implementation program if
certain additional information was supplied. The purpose of this
staff report is to present to the Board the status of the
Districts' implementation program submittals and their
evaluation.

ITEM NO.: 74-16-5

Status Report on Implementation of the State Air Pollution
Emergency Contingency Plan.

RECOMMENDATION

For Information Only.

SUMMARY

Fifteen of the 19 air pollution control districts subject to the
Board's Air Pollution Emergency Contingency Plan have adopted
regulations to comply with provisions of the State Plan. It is
expected that the other 4 districts will adopt regulations before
September 30, 1974.

Stationary source curtailement plans are being developed at the
direction of the districts to complement the episode regulations.
Administrative procedures for the districts are being developed
which will detail responsibilities in the event of an episode.
Three districts have developed and submitted these procedures.

During the period June 26-29, 1974 levels of oxidant above Stage
2 criteria were experienced in parts of the South Coast Air
Basin. During this period it was noted, among other things, that
communication channels need to be defined better, voluntary
traffic reduction needs improvement, interdistrict coordination
procedures are workable and meteorological forecasts are
reliable.

As directed by the Board, the staff submitted the State and local
plans to the EPA for approval. EPA granted conditional approval
and required several modifications to the District Plans.
Responses to EPA requirements will be developed.

ITEM NO.: 74-16-6

Oxidant Measurements and Emergency Plan Episode Criteria Levels.

Report to be distributed prior to meeting.

ITEM NO.: 74-16-7

Report on the California 24-Hour Ambient Air Quality Standard for
Sulfur Dioxide.

RECOMMENDATION

Hold a public hearing to change the 24-hour sulfur dioxide
standard from 0.04 ppm to 0.10 ppm.

SUMMARY

The present 24-hour standard of 0.04 ppm has insufficient medical
justification and is unnecessarily stringent. The Air Quality
Advisory Committee of the State Department of Health has recently
reviewed available information concerning the health effects of
SO2 singly and in the presence of particulates or ozone. The
Department recommends a standard of 0.10 ppm.

ATTACHMENTS

1. "Sulfur Dioxide" section from August 14, 1973 staff report
on air quality standards.

2. "Recommended California 24-Hour Sulfur Dioxide Ambient Air
Quality Standard," presented to the Board by the Department
of Health in July 1974.

3. Proposed Notice of Public Hearing.

ITEM NO.: 74-16-8

Compliance Status of Rice Growers Association and Rice Mill
Products Facilities in Yolo County.

RECOMMENDATION

No Board action required at this time.

SUMMARY

A hearing on the Yolo-Solano Air Pollution Control District
actions to control emissions from Rice Growers Association and
Rice Mill Products was held at the November 13, 1973 and
continued at the January 10, and March 12, 1974 Board meetings.
On March 12, 1974, the Board found that the District had taken
reasonable enforcement action and instructed the Executive
Officer to follow the progress toward a solution of the problem
and report on the compliance status at the August 15, 1974 Board
meeting.

The staff has visited RGA and RMP and has reviewed progress in
control equipment construction. The required control equipment
is being installed and all sources should be in compliance with
District regulations by the 1974 harvest season.

The District is conducting an ambient air quality monitoring
program in the area adjacent to the facilities. The staff will
work with the District in this effort and in data analysis. If
warranted, a report to the Board will be made after the current
harvest season.

Attached is a staff report on actions the District and C
