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

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

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
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 CO2 control–Characterization of low emitting cook stoves–Understanding black carbon emissions–Characterization of open burning sources
Core Competencies
7
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
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
