  1. MANE-VUPolicy & Science Meeting: A Summary Baltimore, MD November 9-10, 2005 Presented at the Fall 2005 Southeastern Air Directors’ Meeting Charleston, SC November 15, 2005 by Fred Durham, Assistant Director WV DEP, Division of Air Quality

  2. MANE-VU Science & Policy MeetingBaltimore MD, November 2005 • Meeting Objectives • To share and discuss available modeling and data analysis results pertaining to Regional Haze and related SIPs • To facilitate completion of technical elements of SIPs and provide support for the consultation process. • Discuss and identify next steps in MANE-VUs science projects, support for SIPs, and consultation process

  3. MANE-VU Agenda-1 • Welcome & Introductions • (Anna Garcia, OTC and Susan Wierman, MARAMA) -Why we are here, overarching goals and overview of agenda • What’s required? • SIP elements (Susan Wierman, MARAMA) • Consultation process (Anna Garcia, OTC) • What do we know so far? • Reasonable Progress Goals (Gary Kleiman, NESCAUM) • A Regional Look at the MANE-VU Emissions Inventories, Trends, and Projections (Serpil Kayin, MARAMA) • A Regional Look at the MANE-VU Modeling Results • CMAQ Results (Shan He, NESCAUM) • REMSAD Results (Jung-Hun Woo, NESCAUM) • CALPUFF Results (Paul Wishinski, VT) • Preliminary Work Using CEM Data (Alper Unal, NJ)

  4. MANE-VU Agenda-2 • A Regional Look at the MANE-VU Data Analysis Results • Trajectory Clustering Results (NESCAUM) • Emissions/Distance Results and Other Techniques (NESCAUM) • Source Apportionment Results (Rich Poirot, VT) • Rain Results (John Graham, NESCAUM) • What else is needed to complete the SIP process? • Weight of Evidence Approach for SIPs—Methods for combining results in a meaningful way (John Graham, NESCAUM) • Discussion of the Weight-of-Evidence Approach for SIPs—EPA guidance and MANE-VU’s preliminary analysis (Gary Kleiman) • VISTAS Headlines (Pat Brewer, VISTAS)>> Fred Durham • Elements of the Long Term Strategy (Ray Papalski, NJ) • BART & CAIR • Open discussion and contributed presentations • Addressing Regional Haze Pollutants from Industrial Boilers II (Glynn Rountree, American Forest & Paper Association) • Emission Trading (Bob Paine, ENSR Corporation)

  5. Synopsis-1 • MANE-VU has focused on contribution assessment so far • They have applied a wide diversity of technical approaches, including but not limited to: • CMAQ, CMAQ+DDM, REMSAD, CALGRID, CALPUFF, Trajectory Analysis,T-probability, Incremental Prob.,Cluster Weighted Prob., Rotated Coordinate Prob., Residence Time, RAIN monitor data, etc. • Typical examples focus on 4 Class 1 areas: Acadia, Brigantine, Lye Brook and Shenandoah • About the only technique they aren’t using is CAMx • The technical quality of the work appears to be good to excellent • Most of the work has used 2002 and prior emissions inventory data

  6. Synopsis-2 • CMAQ • v4.4 on LINUX Clusters • 36Km U.S. >> 12Km • Boundary Conditions from Geos-Chem • MM5 v3.6.1 & SMOKE • Sulfates look good at monthly average; over-predict in August • Nitrates have poor daily performance; better when averaged monthly; still poor in winter • Ammonium over-predict • OC good except for fire event; EC too high • Overall good extinction best/worst days at Acadia & Brigantine • Good Haze Index at four Class 1 areas • Surprise… visibility most affected by sulfates!

  7. Synopsis-3 • REMSAD • Simpler chemistry runs faster • Can tag Sulfur, Nitrogen, Cadmium, & Mercury • Used in Draft MANE-VU Contribution Assessment • Early runs used EPA Clear Skies inputs • New runs use recent E.I.; track elevated & low sulfur from 32 eastern states • 3 Runs; VISTAS states in Run 2 • Will look at 4 Class I areas inc. Shen. & Brig. using August 6-16 episode • Draft estimates 70% impact at Brigantine comes from non MANE-VU states • Estimate 15% MANE-VU impact at Shen. (SO4)

  8. Synopsis-4 • CALPUFF for BART & other things- 36 Km CALMET using NWS Obs; review 2002 data compared to IMPROVE SO4 - ranked 869 EGU vs. impact on 22 Class I sites- annual avg. is good; the consensus seems to be that BART is a “non-issue” because of EPA’s CAIR decision; Not pursuing exemption modeling • EGU temporal allocation – adjust default profile with CEM data- main difference is monthly variation • Trajectory Clustering & Probabilities – are aggregating by state (maps) & compared 500m trajectories to REMSAD • Q/d; applied regression to get 4 wind sectors; e.g. Shen. most impact from S SW winds; OH & PA most impact; uses CALPUFF chemistry • Percent Time Upwind; e.g. Sulfur - lay back trajectories over residence time emissions and sum by state; use ARC-View and is only qualitative; has some bias

  9. Synopsis-5 • IMPROVE Equation:recognize flaws; seem much less inclined than us to make changes; New IMPROVE sodium is very bad • Source Apportionment: Combined Aerosol Trajectory Tool (CATT) + ATAD vs. HYSPLIT Trajectory + Fast Aerosol Sensing Tools for Natural Event Tracking (FASTNET) + Rural Aerosol Intensive Network (RAIN) data >> DATAFED.NET • RAIN is highly time resolved, continuous PM, SO2, & O3 at high elevation sites (to track transport, etc.) • W.O.E. & SIP Development: • Application of several models/data analyses to provide mutually reinforcing results • Consider relative performance of all techniques and underlying data sources • Methods of combining results in a meaningful way is key to results

  10. Contribution Assessment • Analytical Technique Approach • Emissions Inventory Analysis Data Based • Emissions/Distance Empirical • Incremental Probability “Receptor” based trajectory technique • Upwind Residence Time Empirical/trajectory hybrid • Source Apportionment Receptor model/ trajectory hybrid • REMSAD tagged species “Source” based grid model • CALPUFF + MM5 Dispersion Model • CALPUFF w/ Obs met Dispersion Model

  11. Where MANE-VU is Headed-1 • Many ways of sulfate apportionment are being developed, refined & analyzed • Many of these methods can & will be applied to other species • REMSAD results will come soon & will be used as the principle apportionment tool (just one modeled year) • Other tools will be used to support • Final Contribution Assessment Report – draft December 2005

  12. Where MANE-VU is Headed-2 • Develop normalized ranking plots for all receptor sites • Design qualitative “likely-impact” groupings • Devise weighting scheme for techniques to establish final contribution/ranking from each state to each Class 1 area • Evaluate each state’s contribution to all Class 1 areas • Determine necessary relative and absolute emission reductions to achieve Reasonable Progress, using 2018 glide path as guide

  13. Discussion • RUSTY the Rain-Dog
