NEW SOURCE REVIEW MODELING New Source Review (NSR) modeling, also referred to as construction permitting or preconstruction permitting, predicts the effect of a new source on air quality using tools such as air models as part of the permitting process. Sage has many years of experience in all facets of New Source Review modeling: Prevention of Significant Deterioration (PSD) permits which are required for new major sources or a major source making a major modification in an attainment area Nonattainment NSR permits which are required for new major sources or major sources making a major modification in a nonattainment area Minor source permits In addition to modeling for National Ambient Air Quality Standards (NAAQS), PSD increments, and state standards, NSR modeling must often address air toxics. Sage modelers are experienced at using the following air models: Screening Models (SCREEN3, TSCREEN, VISCREEN, etc.)

Air Dispersion Modeling SoftWright is pleased to assist you in providing topographic elevation data that can be supplied to popular air dispersion modeling software. Typically, a study in a region is first done by identifying a specific location and evaluating out to a distance of approximately 50 km from that location with receptor grid spacing at a course setting such as 1000 meters. When the impact area has been located, the study is rerun in a smaller area with the receptor grid spacing tightened up to more accurately display the level of contamination in the impact area. This type of iterative process is repeated over smaller geographic areas and with tighter receptor grid spacing until contaminant levels are ascertained. In addition to software necessary to do this modeling, generally two other things are required if terrain data is necessary for your model. First of all you must acquire DEMs for the geographic region where you need to perform the study. These can be supplied in several resolutions and numerous file formats . Many of the air dispersion modeling software packages do not read the DEMs directly, but rely on an intermediate software package to create an ASCII data file containing the actual input information for the air dispersion modeling software. These files typically contain details calculated from input provided by you about the area for your study and receptor spacing.

Training Sectors Chemicals Law Firms Petroleum Transportation Air Dispersion Modeling Air Dispersion Modeling CTEH performs atmospheric dispersion modeling (ADM) for emergency, planning, and permitting situations. ADM is used to estimate temporally- and spatially-resolved atmospheric concentrations of a chemical by using release, meteorological, and topographical information. Release rate estimates are developed by CTEH chemical engineers using state-of-the-science algorithms and estimation tools. Meteorological information is obtained through multiple methods, and topographical information is included where appropriate. This important estimation process helps the toxicology component of CTEH to assign areas of risk to a particular event. CTEH uses SAFER STARâ„¢ (SAFER) to help manage an emergency and to provide early warning to those who may risk exposure to a potentially harmful substance. SAFER accurately models the effects of chemical accidents (toxic releases, fires and explosions). The program includes state-of-the-science algorithms for addressing atmospheric dispersion, thermal radiation and blast overpressure modeling. In addition, SAFER provides mapping and topographical databases for the region of interest. Once the release site is identified, SAFER rapidly assembles appropriate maps and topographical data. More about SAFER.

Home Services Equipment Search ... Stack / Source Emissions Testing SEARCH BY Industry Method Air Dispersion Modeling Air dispersion modeling can be used to predict the concentration of criteria pollutants at specified ground-level receptors around an emission source. Air quality modeling is used to predict concentrations of air pollutants that disperse and react in the atmosphere. Air Dispersion Modeling simulates emissions as they are transported through the atmosphere. These models take into account atmospheric conditions, such as meteorological inputs; and source data, including stack heigh and emissions rates. Dispersion Modeling provides necessary data for regulatory applications; and can be used to assess control technologies. Regulatory applications can include State Implementation Plan (SIP) compliance, to meet permit application requirements for New Source Review (NSR) and Prevention of Significant Deterioration (PSD) regulations. Using EPA approved Air Dispersion Models, CleanAir has conducted dispersion modeling scenarios for many of our industrial clients. Successful projects have included modeling for NSR permits, evaluating impacts using control technology, and determining PSD applicability. State Implementation Plan (SIP) revisions for existing sources New Source Review (NSR) National Ambient Air Quality Standard (NAAQS) Prevention of Significant Deterioration (PSD) Clean Air Interstate Rule (CAIR) Clean Air Mercury Rule (CAMR) CleanAir is experienced in the application of EPA-approved models for criteria pollutants. We have been successful providing compliance results using the refined dispersion models, including the EPA preferred AERMOD Modeling System, for point source emissions and fugitive sources. With our expertise in conducting Point Source and Ambient testing and our in-depth understanding of the model inputs and variables, CleanAir can provide a successful modeling system approach.
