EPA’s role in air quality Public health agency
Science based Healthy dose of policy Integrate science and policy to better protect public health
Clean Air Act Mandates the regulation of six criteria pollutants: O3, PM, NO2, SO2, Pb
and CO Source emissions Interstate transport Acid Rain Air Toxics Stratospheric ozone Permits and enforcement

EPA’s role in air quality Headquarters offices (mostly in DC and RTP)
Policy oriented Review and set National Ambient Air Quality
Standards (NAAQS) Design national plans and promulgate the necessary
regulations to implement the NAAQS and protect public health
Regional Offices Representing specific geographic areas of the United
States Headquarters program implementation Extramural activities Every Region is different 3

EPA’s Structure with Regards to Air Quality
Office of Research and Development (ORD) Conduct scientific research to support the
program offices and Regions Housed in labs around the country (most in RTP) Look at a variety of air quality issues

What data are traditionally used?
Ozone PM2.5

What data are traditionally used? Ground based measurements
Collected data usually conform to data collected during health studies
Used for a wide variety of purposes The more information the better Networks have strict quality assurance
requirements Decent time resolution Not always the best spatial resolution

Nontraditional data uses at EPA Exceptional events
Fires Saharan dust
Weight of evidence Integrated Science Assessments, Risk and
Exposure Analysis, Policy Assessment for some of the criteria pollutants

Nontraditional data uses at EPA Relating satellite measurements to ground
based measurements
Taken from PM ISA (December 2009)8

Current State of Things Policy makers, however, still rely almost solely
on traditional ground based measurements for Attainment designations Air Quality Index State Implementation Plans Ground truthing air quality models
Why? Regulations Current limitations of satellite data Funding issues

Recent Emphasis to Enhance Air Monitoring Capability
Sensors and Apps Innocentive Challenge
Science fiction is slowly becoming science fact Large leaps in computing power and individual
creativity and innovation Concerns about public perception and
expectations

What would help More web based remote training sessions on satellite data
and how to access and utilize the data for regional office staff
Continued development of analyses using satellite data that act as weight of evidence for attainment decisions in SIPs and aid in the design of effective control strategies to help States meet the NAAQS
Continued development of analyses to confirm influences from exceptional events (e.g. dust and fires)
On the modeling front, develop uncertainty estimates for deterministic models like CMAQ
Development of sensor technology to the point where satellite monitoring could be classified as Federal Equivalent Method 11
