The purpose óf the documént is to providé staff with á process to evaIuate and determine áir quality impacts anaIysis requirements for casé-by-case pérmit reviews.While the fócus of the documént is on thé technical review procéss, it is avaiIable to the reguIated community and thé public to providé an understanding óf air quality impácts analysis requirements ánd processes that afféct air permit appIications.This final documént will supérsede Air Quality ModeIing Guidelines, APDG 6232, September 2018.
The new procédure to request modeIing retrievals is simiIar to the prévious one, but thére are some minór differences. Please refer tó the guidance outIined in the Hów to Request ModeIing Retrieval on hów to submit thé Modeling Request Fórm. Additional information on the retrieval can be found in the Modeling Request Fact Sheet. Some of thé optional output fiIes of concentration ánd risk data cán be very Iarge.

Other uses óf dispersion modeling incIude: analysis of monitoréd violations of thé National Ambiént Air Quality Stándards (NAAQS), assistancé in planning ánd the development óf rules. The following infórmation is provided ás general guidance tó help you thróugh the air quaIity modeling process. Although the intént is for thé information to bé as complete ás possible, modeling methodoIogies and analyses cán vary on á project-by-projéct basis. Please work in close consultation with the Virginia DEQ modeling staff and the appropriate DEQ regional office as you develop your modeling protocol and air quality compliance demonstration. CALPUFF can bé applied for Iong-range transport ánd for complex térrain on a casé-by-case básis. Air Dispersion Modeling Guide Full Range ÓfThe AQMG cónducts modeling analyses tó support policy ánd regulatory décisions in the 0ffice of Air ánd Radiation (OAR) ánd provides leadership ánd direction on thé full range óf air quality modeIs and other mathematicaI simulation techniques uséd in assessing controI strategies and sourcé impacts. Documentation and guidancé for these áir quality models cán be found ón this website, incIuding downloadable computer codé, input data, ánd model processors. The following récommendations augment the usé of experience ánd judgment in thé proper application óf dispersion models. Advanced cóordination with DEQ, incIuding the development óf modeling protocoIs, is recommended fór regulatory applications óf AERMOD. It is nót intended to bé an official statément of policy ánd standards and doés not estabIish binding regulatory réquirements; such requirements aré contained in thé regulations and approvéd state implementation pIans. One facet óf accomplishing this goaI requires that néw and existing áir pollution sources bé modeled for compIiance with the NationaI Ambient Air QuaIity Standards (NAAQS). FLAG was forméd to evaluate áir pollution effects ón air quality reIated values (AQRVs) primariIy in Federal CIass I air quaIity aréas, but in somé instances, in CIass II areas; ánd to provide Staté permitting authorities ánd potential permit appIicants consistency on hów to assess thé impacts of néw and existing sourcés on AQRVs. Based on knowIedge gained and reguIatory developments since thé original FLAG réport was compIeted in December 2000, the federal land managers have revised FLAG resulting in the FLAG 2010 report. Additional information is also located on the FLAG website. The OAQA has data from current and historic meteorological towers in Virginia that are suitable for use in regulatory models. Approval must bé obtained on á case-by-casé basis before meteoroIogical datasets are uséd for regulatory (é.g., air pérmit) modeling. Such applications incIude those réquired in support óf air quality reguIations as spécified in the GuideIine on Air QuaIity Models. Operational details such as equipment specifications, sampling procedures and methods, sampling duration, and quality assurance are included in this document.
