  1. Initial Applications of the Control Strategy Tool (CoST) within the Emissions Modeling Framework Alison M. Eyth UNC Institute for the Environment David Misenheimer, Darryl Weatherhead, Larry Sorrels U.S. EPA Jim Wilkinson, Gregory Stella Alpine Geophysics, LLC October 2, 2007

  2. Purpose of CoST • Support the preparation and analysis of future year emission control strategies for point, area, and mobile sources • Track information on control measures, their costs, and the emission sources to which they apply • Facilitate multi-pollutant analyses, including criteria pollutants and their precursors, HAPs, and greenhouse gases Institute for the Environment

  3. CoST and the EMF Import inventory into the EMF 1 Create and run a Control Strategy 2 Export the controlled inventory for input to SMOKE 3 SMOKE Compute Cluster Emissions Modeling Framework Server NEI Data Grown by SMOKE A Control Strategy 2020 Base Emission Inventory 2020 Control Case Inventory 1 Control Measure Data x = 2 PC Clients 3 Institute for the Environment

  5. Control Strategy Settings • Summary Parameters: • Strategy Type, Region, Target Pollutant, Cost Year, Discount (Interest) Rate • Emission inventories to use, and optional Inventory filter and County File • Control Measures to consider • Constraints (e.g. max cost per ton) • Next: Review important CoST features Institute for the Environment

  15. Optionally Set Constraints Minimum Emissions reduction (tons) or Control Efficiency (%) Maximum Cost per Ton or Total Cost for a Source Institute for the Environment

  16. Outputs are Stored in the EMF Institute for the Environment

  17. Results are Generated for Multiple Pollutants (e.g., PM10, EC, PM2.5) Institute for the Environment

  18. FY 2007 CoST Applications • Mobile Source Strategy Comparison • A new strategy type was needed: Apply measures in series • Software was validated against an independently created control strategy • Started Comparison to Independently Generated Ozone NAAQS Regulatory Impact Assessment for Point and Area Sources • Greenhouse Gas Test Application Institute for the Environment

  19. Goals of Greenhouse Gas Test Application • Evaluate the impact of traditional control measures on GHG emissions • Augment existing control measure data with GHG cobenefits information • Obtain emissions inventory data with GHG information • Ensure that CoST in the EMF can report results for cobenefit pollutants Institute for the Environment

  20. Collection of Measure Data • Wanted to gather information on cobenefits of traditional controls on GHGs • Jim Wilkinson and Greg Stella of Alpine Geophysics, LLC reviewed various data sources • Generally, they found that GHG control measure data was difficult to find • Specific control efficiencies are needed • Compromise: EC and OC records were added to Control Measure Database for existing measures based on PM 2.5 control efficiencies Institute for the Environment

  21. Augmenting the Inventories • Since a source level GHG US emissions inventory is not available, we examined ways to add some relevant pollutant to the existing inventory • We developed a SQL query to add records for EC to an existing modeling inventory (within the EMF) • EC data was based on PM 2.5 speciation cross-reference and profile information input to SMOKE which was also in the EMF • Having all the data in the EMF database made this data augmentation easy! Institute for the Environment

  22. Running CoST • We ran CoST within the EMF for three cases: • Cement and FerroAlloys only (ptnonipm) • All non-utility point sources • Nonpoint inventory (excluding area fugitive dust, agriculture, and fire) • Results were summarized by control measure, SCC, state, county, etc. and were exported as CSV files Institute for the Environment

  23. Cement Sector Result Summary for CA by Pollutant Controlled Emissions Starting Emissions Institute for the Environment

  24. Summary • Some GHG-related control measure data was obtained • The 2020 point and nonpoint modeling inventories were augmented with a GHG-related pollutant (EC) • The software was successfully used to output the GHG cobenefits for EC based on available control measures Institute for the Environment

  25. Recommendations forFuture GHG-Related Work • Adding greenhouse gases to the NEI would really open doors for analyses much broader than the ones described here • The control measure database could be augmented with actual GHG control data via targeted data collection efforts • Additions to the software for other efforts should also be useful for GHGs Institute for the Environment

  26. Possible Enhancements in FY08 • Complete the validation of the ozone RIA point and area strategies. • Consider existing controls before applying measures to sources. • Provide improved support for add-on controls. • Allow grouping and versioning of control measures • Support average day inventories in addition to annual • Support for application of control programs to projected emission inventories. • Combine results of multiple control strategies. • Further facilitate comparison of strategies. • Export results to Shapefiles Institute for the Environment
