ENVIRONMENTAL PROTECTION AGENCY
[FRL-9170-1]
Science Advisory Board Staff Office; Notification of a Public
Teleconference of the Air Quality Modeling Subcommittee of the Advisory
Council on Clean Air Compliance Analysis (Council)
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The EPA Science Advisory Board (SAB) Staff Office announces a
public teleconference of the Air Quality Modeling Subcommittee (AQMS)
of the Advisory Council on Clean Air Compliance Analysis (Council) to
review additional information on particulate matter inventories for
EPA's air quality modeling work for the Second Section 812 Prospective
Benefit-Cost Study of the Clean Air Act.
DATES: The AQMS will conduct a public teleconference on August 11,
2010. The teleconference will begin at 12 noon and end by 2 p.m.
(Eastern Time).
ADDRESSES: The teleconference will be conducted by telephone only.
FOR FURTHER INFORMATION CONTACT: Any member of the public wishing to
obtain general information concerning the
[[Page 37795]]
public teleconference may contact Ms. Stephanie Sanzone, Designated
Federal Officer (DFO), via telephone at (202) 343-9697 or e-mail at
[email protected]. General information about the Council can be
found on the EPA Web site at http://www.epa.gov/advisorycouncilcaa.
SUPPLEMENTARY INFORMATION: Pursuant to the Federal Advisory Committee
Act (FACA), 5 U.S.C., App. 2, notice is hereby given that the Air
Quality Modeling Subcommittee (AQMS) of the Advisory Council on Clean
Air Compliance Analysis (Council) will hold a public teleconference to
discuss additional information on estimates of fine particulate matter
(PM2.5) emissions and air quality changes for the Second
Section 812 Benefit-Cost Analysis of the Clean Air Act. The Council was
established in 1991 pursuant to the Clean Air Act (CAA) Amendments of
1990 (see 42 U.S.C. 7612) to provide advice, information and
recommendations on technical and economic aspects of analyses and
reports EPA prepares on the impacts of the CAA on the public health,
economy, and environment of the United States. The Council is a Federal
Advisory Committee chartered under FACA. The AQMS will provide advice
through the Council and will comply with the provisions of FACA and all
appropriate SAB Staff Office procedural policies.
Background: Pursuant to Section 812 of the 1990 Clean Air Act
Amendments (CAAA), EPA conducts periodic studies to assess benefits and
costs of programs implemented pursuant to the Clean Air Act. The
Council has provided advice on an EPA retrospective study published in
1997 and an EPA prospective study completed in 1999. EPA initiated a
second prospective study to evaluate the benefits and costs of EPA
Clean Air programs for years 1990-2020. The Council has previously
provided advice on the analytical blueprint for this study. EPA's
Office of Air and Radiation (OAR) is now nearing completion of the
analytical work for the second prospective study. The AQMS met on
February 19, 2010 [Federal Register Notice dated January 26, 2010 (75
FR 4070-4071)] to review technical documents pertaining to modeling of
air quality for seven emissions scenarios: a 1990 baseline simulation;
and simulations for 2000, 2010 and 2020 with and without the CAAA. The
AQMS held a follow-up teleconference meeting on March 15, 2010 to
discuss information provided by EPA on proposed adjustments to
estimated emissions of primary PM2.5 from particular sources
and the effects on the estimated air quality changes between scenarios
based on those revised emissions estimates. Materials for the February
19 and March 15 meetings are available on the Council Web site at
http://yosemite.epa.gov/sab/sabproduct.nsf/fedrgstr_activites/2nd%20Prospective%20812%20-%20AQMS?OpenDocument.
In a resulting advisory report (EPA-COUNCIL-10-002), the AQMS
recommended that ``the scaling procedure [for PM2.5] should
be clearly documented in the draft modeling report * * * or in a
separate document that also describes the MATS [Modeled Attainment Test
Software] adjustment procedure and results, including the results of
MATS with and without scaling of emissions.'' In response to this
recommendation, the EPA has provided a memorandum (dated June 14, 2010)
that documents the adjustment procedure and PM2.5 results
for a number of metropolitan areas. The purpose of the August 11, 2010
teleconference meeting is to discuss the MATS memorandum and provide
final advice to the Council and the Agency on the reasonableness of the
primary PM2.5 emissions revisions and the resulting re-
estimated air quality concentration changes between scenarios that will
be used for benefit estimation in the Second Section 812 Prospective
Study.
Technical Contacts: The Office of Air and Radiation technical
contact for the Second Section 812 Benefit-Cost Analysis of the Clean
Air Act is Mr. Jim DeMocker at (202) 564-1673 or [email protected].
Availability of Meeting Materials: The meeting materials, including
the review materials and meeting agenda for the August 2010
teleconference, will be posted to the Council Web site at http://www.epa.gov/advisorycouncilcaa prior to the meeting. EPA draft
documents provided to the AQMS also are available at http://www.epa.gov/oar/sect812/prospective2.html.
Procedures for Providing Public Input: Interested members of the
public may submit relevant written or oral information for the AQMS to
consider on the topics of this advisory activity. Oral Statements: In
general, individuals or groups requesting an oral presentation at a
teleconference meeting will be limited to three minutes per speaker,
with no more than a total of one hour for all speakers. Interested
parties should contact Ms. Sanzone at the contact information provided
above by August 4, 2010, to be placed on the public speaker list for
the August 11, 2010 meeting. Written Statements: Written statements
should be received in the SAB Staff Office by August 4, 2010, so that
the information can be made available to the AQMS for their
consideration prior to the meeting. Written statements should be
supplied to Ms. Sanzone in the following formats: one hard copy with
original signature and one electronic copy via e-mail (acceptable file
format: Adobe Acrobat PDF, MS Word, WordPerfect, MS PowerPoint, or Rich
Text files). Submitters are asked to provide electronic versions of
each document submitted with and without signatures, because the SAB
Staff Office does not publish documents with signatures on its Web
sites.
Accessibility: For information on access or services for
individuals with disabilities, please contact Ms. Sanzone at (202) 343-
9697, or via e-mail at [email protected], preferably at least
ten (10) days prior to the meeting, to give EPA as much time as
possible to process your request.
Dated: June 23, 2010.

Director, EPA Science Advisory Board Staff Office.
