U.S. Environmental Protection Agency's PM Supersites
Program—A Major Successful Collaborative Air Quality
Program Supporting States and Regional Organizations in
Their Approaches to Reduce PM Levels in Air on Urban
and Regional Scales

PM Supersites Program Objectives

~ To provide key stakeholders - state, local, tribal, and Federal agencies, regional planning
organizations, the private sector, and the general scientific comunity - with:

•	Sampling and analysis methods to measure the chemical and physical
characteristics of PM and important precursor species,

•	Enhanced temporal and compositional characterization that complements routine
ambient air monitoring networks, and

•	Insights into policy relevant phenomena that corroborate current policies, cause
rethinking and modification, and provide direction for future policy formulation.

Initial Collaborations

Used by Stakeholders

State, Regional, Federal Agencies And
Private Sector In Support of
SIP Development:

•	Model Performance Evaluation
¦ Model Application

•	Data Analysis
Yielding Improved:

Source-Receptor Understanding and
SIPs that Are More Cost Effective and
Efficient at Reducing Ambient PM Levels
and Related Species on Urban and Regional Scales
Resulting in Better Protection of Public Health and Welfari

PM Supersites Program and Related Studies
Synthesis of Key and Policy Relevant Findings

Coordinating and Collaborating With Related Air Quality Studies
In the Eastern United States (Over 30 Programs & Studies Involved)

•	Coordination included State Agencies

•	Federal Agencies (e.g., DOE, Federal
Highway Administration)

•	National Monitoring Networks
(EPA Criteria Pollutants, NOAA
Upper Air Meteorology)

•	Private Sector conduction additional
measurements at existing and new sites

•	Southeastern Canada via Meteorological
Service of Canada

Three (3) Aircraft Coordinated
During Summer Intensive
Monitoring Periods;
Two (2) Fly During January 2002

- U MD Plane Flight Path
-} LADCO Planes Flight Paths

17 Science/Policy Relevant Questions -
Technical Support for Synthesis (Journal Articles)
(General Themes Addressed)

•	Methods (Qs 1-3)

•	Characterization (Qs 4-8)

•	Source Apportionment - Receptor and Emissions

•	Based Chemical Transport Models (Qs 9-11)

•	Atmospheric Processes (Qsl2 — 15)

•	Emissions Estimates (Q 16)

•	Conceptual Models

•	Integrated Synthesis of Key Atmospheric Sciences Findings"

•	Policy Relevant Findings Based on Synthesis"

•	Health Relevant Findings Based on Synthesisb

•	Executive Summary

•	Policy One Page Statements

Stakeholders -

Policy Makers & Air Quality Managers In The Public And Private Sectors —
Obtain Policy Relevant Information To Support Policy Decisions Related To
Approaches To Reduce PM On Urban and Regional Scales, and Thus, To
Reduce The Adverse Health And Ecological Effects Of PM Related Air Pollution
