Air Dispersion Modeling Basics for Permitting GHD Qi Zhang

This training aims to provide some basics of air dispersion modeling procedures for air permit applications. Air dispersion modeling analysis is a key part to any Prevention of Significant Deterioration (PSD) permit application process to demonstrate a project is in compliance with the National Ambient Air Quality Standards (NAAQS), and the PSD increment requirements. Louisiana Department of Environmental Quality (LDEQ) currently does not require air dispersion modeling to be submitted with State Minor Permit Applications. On the other hand, the Texas Commission on Environmental Quality (TCEQ) does require air impact analysis with dispersion modeling for any minor or major New Source Review (NSR) permit applications. A dispersion modeling analysis starts with a significant impact analysis (SIA) to include all project-wide emission increases for all criteria pollutants. The presentation will cover the basics of setting up sources, buildings, property boundaries or fence lines and receptor grids, along with terrain processing and meteorological data parameters. Should impacts of any modeled pollutants are greater than the significant impact level (SIL), an area of impact (AOI) will be determined, and the analysis will move forward with a cumulative analysis, including nearby source impacts and background concentrations for the NAAQS analysis. PSD increment will also need to be addressed. A cause and contribution, also known as the culpability analysis, will follow if the cumulative analysis shows any exceedances to the NAAQS or PSD increment standards. As time allows, this training will also walk through the air toxics modeling requirements of the LDEQ and the health effects analysis procedures of the TCEQ.   / qi-zhang-17839512   Modeling Culpability Analysis, Daylight Only Restrictions, Engines and Tank Maintenance, NAAQS, PM 2.5, Carbon Monoxide, Sulfur Dioxide, SO2, SIL, PM2.5 Preliminary Monitoring Secondary Formation, Assessing Primary and Secondary PM 2.5 Impacts, AERMOD Analysis, Eulerian Grid Models, CAMx, UAM-V, Ozone Monitors, Modeling Formation, Modified vs Affected, Physical Change or Change in the Method of Operation, Alternative Fuel, Construction, Reconstruction, Modified, Modification, NSPS, Minor New Source, Major New Source, Permit Representations, Replacement in Kind, Maximum Allowable Emission Rate Table (MAERT), Storage Tank Emissions Changes, Up to Date Emission Calculations, Affected Unit, Debottleneck, Debottlenecked, Increase in Emissions, Full Design Capacity, Potential to Emit, PTE, PTE to PTE Comparison, NSR Applicability Analysis, PAE vs PTE, Emissions Baseline, Contemporaneous Window, Major NSR Applicability, 5 Years Following, 10 Year Baseline, Air Permitting Alphabet Soup, This is Easy, Air Permitting in Texas, Prevention of Significant Deterioration, PSD, Major NSR Reapplicability Evaluation, Non-Attainment, Baseline Actual to PTE Basis, Baseline Actual to Projected Actual Comparison, Top Down vs Three Tier BACT,
