All of these influences have resulted in significantly longer AERMOD model run times as compared to the predecessor regulatory model, ISCST. ...
A laboratory study was done to investigate dispersion of buoyant emissions from near surface sources in urban areas. ...
Modeling Requirements Given the relatively limited time between promulgating a SO2 NAAQS (with an entirely new form and averaging period) and the deadline for submitting initial attainment designations, EPA did not expect States to provide refined dispersion modeling information along with their initial designation ...
Development of Required Emission Reductions For TR, EPA first determined via air dispersion modeling which states (considering all emissions statewide) had a significant impact on an out-of-state nonattainment area (or maintenance area), where EPA defined significant as 1% of the respective NAAQS. ...
The U.S. EPA Air Quality Modeling Group (AQMG) recently released a new guidance document for NO2 modeling. ...
Abstract In 65 FR 21506 (dated April 21, 2000), the United States Environmental Protection Agency (U.S. EPA) proposed revisions to its air dispersion modeling guidance, found in 40 CFR 51, Appendix W ("Guideline on Air Quality Models") that included replacing the Industrial Source Complex (ISC) model with the ...
In the near future AERMOD PRIME will officially replace the Industrial Source Complex Short-Term model, Version 3 (ISCST3) as the preferred Environmental Protection Agency (EPA) air dispersion model. Unlike the ISCST3 model that requires the simple selection of urban or rural default settings, the AERMOD ...

This paper summarises the management and procedural issues that led to the successful development of AERMOD and CALPUFF and how they will come to be approved regulatory models by the US-EPA in the next few months. The legal requirements for constantly updating models is contained in the 1977 Clean Air Act that requires the US-EPA ...

The legal requirements for constantly updating models is contained in the 1977 Clean Air Act that requires U.S. EPA to publish a 'Modeling Guideline' and to hold a hearing every three ...
Environmental Protection Agency’s (EPA) Risk Management Program (RMP) regulations, require facilities to develop a formal Risk Management Program (RMProgram) and to register and submit a Risk Management Plan (RMPlan). ...
