ITEM #89-6-1

Adopt Resolutions 89- and 89- approving the Long-Range
Research Plan, dated March, 1989, and the Indoor Air
Quality/Personal Exposure Assessment Five-Year Study Plan, dated
March, 1989.


In establishing the State's approach to clean air, the
Legislature: has declared that an effective research program is
an integral part of the broad-based statewide effort to combat
air pollution in California; has directed the Air Resources Board
to administer and coordinate all air pollution research funded,
in whole or in part, with state funds; has directed the Air
Resources Board to establish objectives for air pollution
research; and has directed the Air Resources Board to appoint a
Research Screening Committee to give advice and recommendations
with respect to air pollution research projects funded by the

In order to comply with these mandates from the legislature, the
Board meets, each year, with its Research Screening Committee, to
review the Board's research program, as outlined in the Long-Range
Research Plan. This Plan is prepared by the staff, with
guidance from the Research Screening Committee.

The Long-Range Research Plan contains a section describing the
Board's goals and objectives and related extramural research
projects, a section listing recently completed research projects,
and a section describing each of the research projects proposed
for the next fiscal year. These projects are divided into six
study areas:

Diesels and Motor Vehicles;
Toxic Air Contaminants;
Stationary Source Emissions Inventory and Control;
Regional Air Quality Studies;
Health Effects; and
Vegetation Effects.

For each study area, there is a prioritized list of research
projects proposed for the next fiscal year, a figure which
relates these projects to ongoing and future work, and a detailed
discussion of each proposed project. The discussions include a
summary of the research problem, relationship to previous work,
description of the proposed approach, and identification of
benefits to be provided by the study.

This year's Long-Range Research Plan features projects to support
the Board's activities to reduce emissions from motor vehicles;
support the introduction of clean burning fuels; add to our
knowledge of the sources, fate and effects of toxic air
contaminants; provide bases for controlling stationary source
emissions; better characterize the effects of agricultural
burning; improve our ability to analyze regional air quality
problems; better define the effects of exposure to air pollutants
on human health, and better define the extent of air pollution
damage to all forms of vegetation.

The Board also conducts a special research program to obtain
information regarding indoor air quality and personal exposures
to Californians to air pollutants. Health and Safety Code
Section 39660.5 requires the Board to consider indoor exposures
to toxic pollutants in assessing the risk posed by them.
However, little information is available regarding indoor
exposures. The information obtained through the Indoor Air
Quality/Personal Exposure Assessment Five-Year Study Plan will be
used by staff to develop more accurate risk assessments,
especially for toxic pollutants considered under the Board's
Toxic Air Contaminants Program.

ITEM #89-6-2

Public Hearing to Consider the Adoption of an Emission Inventory
Criteria and Guidelines Regulation Proposed Pursuant to
Requirements of the Air Toxics "Hot Spots" Information and
Assessment Act of 1987.


The staff recommends that the Board adopt the proposed emission
inventory criteria and guidelines regulation.


The Air Toxics "Hot Spots" Act (the "Act") requires that the ARB,
in consultation with the districts, develop criteria and
guidelines for the preparation of site-specific air toxics
emission inventory plans by specified facilities by May 1, 1989.
For facilities to which the Act applies, facility operators must
prepare and submit these plans to the air pollution control
districts by August 1, 1989.

The districts must approve, modify, or return the plans to the
facilities for revision within 120 days of receipt. After a
district approves a plan, the facility operator must implement
the plan within 180 days and submit to the district an emission
inventory report containing the toxics emission data and other
required information as set forth in the Act and the proposed

The Act specifies conditions that must be met for the district to
approve a plan and it sets forth requirements that must be
included in the guidelines. To comply with these conditions and
requirements, the proposed regulation includes specifications for
the components of the inventory plan and report, reporting forms,
requirements for emission quantification by source testing and
other measurement or by acceptable estimation methods, a
separation of the list of 326 toxic substances into two groups
with differing inventory requirements, and other specifications
to ensure acceptable emission inventories. The proposed
regulation reflects a thorough evaluation by the staff of the
minimum level of detail of information needed to fulfill the
requirements of the Act and to support the AB 1807 process.
