Office of Research and Development Frank Princiotta, Director, Air Pollution Prevention & Control Division, National Risk Management Research laboratory NRMRL, ORD, EPA March 18, 2014 On-Site Contractor Bidder’s Tour Briefing: Air Pollution Prevention & Control Division ‘s Research Program More Information: http://www.epa.gov/nrmrl/appcd/basic.html

2. 1 APPCD Mission We support the Agency’s environmental protection goals by: –Promoting development of cost effective air pollution prevention and control approaches: Combustion Sources: power plants, cook stoves Manufacturing and processing industries Sources of indoor air pollution –Characterize stationary (including non-point sources) and mobile sources of air pollutants –Provide direct support to Agency’s regulatory and enforcement programs

3. 2 Examples of Major Accomplishments Developed Sulfur Dioxide control technology Developed Low NOx and Reburning Technology Control of Mercury from Combustion Sources Developed non-point source monitoring capability; applied to roads, fugitive sources, e.g.,oil & gas operations Characterized important sources of indoor air pollution (PCBs, radon, mold, formaldehyde) Identified and Evaluated CFC Substitutes Characterized Biogenic Sources Developed World Class MARKAL Energy/Env. Data Bases Innovated MSW Decision Support Tool Red: Major In-House Contribution

5. APPCD Core Competencies Combustion; coal, natural gas, biomass/cookstoves Source Characterization Indoor Air Characterization and Mitigation Global Climate Change Emissions & Mitigation APPCD has world class capabilities in four main program areas:

6. 5 Combustion Wide variety of bench- and pilot-scale combustion systems that can be used to evaluate: –Fundamental processes that influence air pollutant formation –Options to control emissions using flue gas cleaning and/or combustion modification Areas of emphasis include: –Characterization of Mercury & other air toxics from coal-fired boilers –Control of fine particulate matter and its precursors –Evaluate Oxy-fuel technology for CO 2 control –Characterization of low emitting cook stoves –Understanding black carbon emissions –Characterization of open burning sources Core Competencies

7. 6 Source/Emissions Characterization Dynamometers to measure emissions from –heavy duty diesel vehicles –medium duty trucks –light duty vehicles (stationary and transportable) –small engines Portable laboratory (diesel truck pulling a sampling trailer) for on-road field testing of fine particulate matter and gaseous emissions Optical Remote Sensing (ORS) equipment (FTIRs, IR diode laser, UV and deep UV absorption spectroscopy) for real-time measurement of pollutants emitted from area (non-stack) sources A mass spectrometric method that combines high selectivity (compound specificity) and on-line measurements with high sensitivity –REMPI (Resonance Enhanced MultiPhoton Ionization) instrument Core Competencies

8. 7 Source / Emissions Characterization Evaluation of mobile source emission reduction systems –Effects of alternate fuels –Chemical characterization of exhaust –On-road testing using DEAL (Diesel Emissions Aerosol Laboratory) Application/development of advanced measurement methods –ORS on fugitive sources –Development of new optical sensors

9. 8 Indoor Air Quality Small chamber testingLarge chamber testing Validation in test house IEQ Modeling Capabilities: Chemical Pollutants
