1 SEMAP Modeling Plans and Status James Boylan Georgia EPD – Air Protection Branch SEMAP Air Quality Modeling Lead Spring Grants/Planning Meeting May 23, 2012 – Atlanta, GA
2 SEMAP ProjectSouthEastern Modeling, Analysis, and Planning (SEMAP) ProjectManaged through SESARMSame group of states that were involved with SAMI, VISTAS, and ASIPAL, FL, GA, KY, MS, NC, SC, TN, VA, WV
3 Outline Emission Inventory Development WRF, SMOKE, CMAQ Future Year Projections for O3, PM2.5, RHOzone Emission SensitivitiesRegional Haze Periodic Reporting
4 Important NoteSEMAP states do not have any moderate or serious ozone nonattainment areas & all PM2.5 monitors are meeting the NAAQS.Regional Haze periodic reports do not require photochemical modeling.Most likely, none of this modeling will be used in any SIPs.
5 Emission Inventory Emissions Inventory Contractors AMEC/Alpine Point source (EGU and non-EGU), fire, and on-road mobile (MOVES) emissions.TranSystems Area and non-road (including MAR) emissions.“Actual” Emission Inventory (2007)Used for model performance evaluations“Typical” Emission Inventory ( )EGUs and firesUsed for model projections and RRF calculationsFuture Year Inventory – 2020Growth & Control factors for EGU point, non-EGU point, area, and MARRerun NONROADInventory mode ratio method for MOVES (proxy FY)Inventory mode ratio method for MOVES (proxy FY): SMOKE ready emissions by each state (could be more than one county); can be different ratio for different areas in a state; for GA four PM2.5 maintenance areas done (ATL, Macon, Floyd, Chattanooga) and additional run for the rest of state

18 Emissions Modeling GT/UNC - SESARM contractor Created SMOKE inputs (NIF to ORL format)Ran SMOKE and SMOKE-MOVESCreated biogenic emissions (BEIS)Added Canada/Mexico and other RPO EmissionsPart 75 data replacement for CEMSDetails on next slideAll 2007 SMOKE files are finished and ready to be used.
19 1. Detect and correct atypical data 2. Gap filling for partial reporters
20 2007 Air Quality Modeling GT/UNC - SESARM contractor 2007 annual modeling with CMAQv5.036 and 12 km gridsModel Performance EvaluationDiagnostic Sensitivity Testing (only if MPE poor)New CMAQv5.0 Model OptionsAdditional new crustal species YESIn-line plume rise for point sources YESIn-line lightning NOx YESIn-line bi-directional NH3 flux NOIn-line biogenic emissions NOIn-line wind blown dust NO
23 2020 Air Quality Modeling 2020 Annual Emisisons Modeling SMOKE for most source sectorsMOVES: Ratio Approach using Inventory Mode2020 Annual CMAQ ModelingProjections of ozone, PM2.5, and regional hazeFollow EPA’s RRF approachOzone Emission Sensitivity ModelingStatewide 30% NOx and VOC emission reductionsOzone season (5 months) at 12 kmPerformed for 10 individual SEMAP states, Maryland, and neighboring RPOs (28 model runs)For all sensitivities, CAMx with DDM could be better.
24 Georgia NOx vs. VOCsSurface NOx reductions were made in Atlanta, therefore small impacts on Augusta since wind was blowing from SC on the two RRF dats. Larger NOx impacts from SC on Augusta during those two RRF days. VVOC=Vistas VOCRed numbers indicate number of days used in RRF calculations
27 Regional Haze Obligations 5-year Periodic ReportsFirst reports due December 2012 (NC, SC)2018 Regional Haze SIP RevisionsDue July 31, 2018Work must begin by mid-2014For all sensitivities, CAMx with DDM could be better.
