ITEM NO.: 91-5-1
Consideration of Appointments of Modeling Advisory Committee
An ad hoc committee of the Board comprising Roberta Hughan and
Jack Lagarias recommends that the Board reappoint Drs. Phil Roth
and John Seinfeld to full, three-year terms on the Modeling
Advisory Committee (MAC), effective on the date of the Board's
action. The committee also recommends that the Board designate
Dr. Seinfeld to continue to serve as the MAC Chairman for a one-year term,
effective on the date of his reappointment.
The Board established the MAC in 1988. The Committee consists of
11 members who are experts in various areas of modeling. The
terms of MAC members are three years, staggered to maintain
continuity. The MAC was established to provide advice to the
staff to: enhance the development and application of regional
models; provide standard methods for selecting, applying,
interpreting, and evaluating models; and provide guidance in
preparing modeling protocols.
The MAC meets approximately quarterly, and since its first
meeting it has provided valuable advice to the staff in such
areas as model performance evaluation, meteorological modeling,
and emission inventories.
Currently the MAC consists of: DR. GLEN CASS (Caltech, DR.
WILLIAM CARTER (Statewide Air Pollution Research Center), DR.
WALTER DABBERDT (National Center for Atmospheric Research), MR.
FRED LURMANN (Sonoma Technology, Inc.), DR. PETER MUELLER
(Electric Power Research Institute), DR. JOYCE PENNER (Lawrence
Livermore National Laboratory), DR. PHILIP ROTH (Private
Consultant), MR. KEN SCHERE (Environmental Protection Agency),
DR. JOHN SEINFELD (Caltech), DR. TOM TESCHE (Alpine Geophysics),
and DR. GARY WHITTEN (Systems Applications International). Dr.
Seinfeld has served as Chairman of the MAC since the committee's
establishment. The terms of appointment for Drs. Roth and
Seinfeld expire this month.
SUMMARY AND IMPACTS
Drs. Roth and Seinfeld have made valuable contributions to the
MAC. Their reappointment would allow them to continue sharing
their expertise and insight with the MAC and the staff.
ITEM NO.: 91-5-2
Public Hearing to Consider Amendments to the Air Toxics "Hot
Spots" Program Fee Regulation, List of Substances, and Emission
Inventory Criteria and Guideline Regulation.
The staff recommends that the Board adopt proposed amendments to
the Air Toxics "Hot Spots" Fee Regulation for recovery of fiscal
year 1991-92 state and air pollution control district costs and
proposed conforming amendments to the Emission Inventory Criteria
and Guidelines Regulation.
The staff also recommends that the Board add 190 compounds to the
Air Toxics "Hot Spots" List of Substances. One hundred thirty-eight of
these compounds are included in lists the ARB is
required to consider when updating the "Hot Spots" list of
substances. Staff is recommending that the remaining 52
compounds be added by the Board's authority to add substances
which, in its judgement, present a potential public health
threat. Staff further recommends corresponding changes to the
Emission Inventory Criteria and Guidelines Regulation.
The Air Toxics "Hot Spots" Information and Assessment Act of 1987
(AB 2588) requires the Board to adopt a regulation which recovers
costs incurred by the Air Resources Board, Department of Health
Services, and local Air Pollution Control Districts in
implementing the Act. The "Hot Spots" Fee Regulation was first
adopted in 1988, assessing fees against all facilities subject to
the Act as required. The Regulation is amended each year to
reflect changes in state and district costs, and in the emission
inventories used to calculate fees.
The staff estimates that a total of $10 to 13 million in Air
Toxics "Hot Spots" Program fees will be collected for Fiscal Year
1991-92. Of this, $3.6 million will be collected to pay for
costs anticipated by the Air Resources Board and the Department
of Health Services.
Legislation passed last year revised the requirements for the
adoption of the Air Toxics "Hot Spots" Fee Regulation. This
year, ARB will have to adopt a regulation with requires local
districts to adopt their own "Hot Spots" fee rules, unless they
have submitted specified information to the Board by April 1.
The proposed amendments would enact this requirement.
The Fee Regulation also contains the list of substances that
determines which facilities are subject to "Hot Spots"
requirements. The Board is required to maintain this list. The
Act requires the listing of certain compounds and requires that
others be considered, if they are included in lists compiled by
other agencies. It also allows the Board to add compounds based
on its own determination that the compounds may present a threat
if present in the ambient air.
IMPACTS OF PROPOSED BOARD ACTION
The proposed amendment would update the fee Regulation to include
updated state and district program costs for fiscal year 1991-92.
The amended regulations would require all districts that do not
meet specified requirements to adopt district fee rules which
recover state and district costs. The amendments would revise
existing fee schedules for 13 districts and makes changes to the
applicability and fee collection provisions.
The proposed amendments would add 190 new substances to the Air
Toxic "Hot Spots" List of Substances. Staff also proposes
conforming amendments to the Emission Inventory Criteria and
Environmental Impacts. Adoption of the amendments to the
regulations is not expected to result in any adverse health,
safety or environmental impacts.
