64. ECCI - An Arkansas Company Specializing In Engineering, Compliance And Construct ECCI engineers are experienced in handling complex air dispersion modeling projects to demonstrate compliance with the Environmental Protection Agency (EPA) and state agencies http://www.ecci.com/envcapable/airdispersion.htm

AIR DISPERSION MODELING ECCI engineers have developed procedures to help define enforceable permit limits to control off-site concentrations of criteria pollutants and hazardous air pollutants to allow successful air dispersion modeling demonstrations while retaining reasonable operational flexibility at the source facilities. ECCI engineers have experience with specialty models and protocols to address unique operations and the associated air emissions including using the United States Army Open Burn and Open Detonation Model at multiple facilities. ECCI engineers have combined actual ambient air monitoring results with conventional air dispersion models to demonstrate off-site compliance in complex situations. Example Projects: Atlantic Research Corporation - Arkansas and Virginia ECCI has completed complex air dispersion modeling projects with HAP emissions from multiple sources and risk assessment driven off-site limitations for emissions from open detonation of waste rocket propellants. These projects utilized standard EPA modeling proto-cols as well as the United States Army Open Burn and Open Detonation Model. References: Terry Leonard, Environmental Director

Visual Determination of the Opacity of Emissions from Stationary Sources Federal New Source Review (NSR) Permits Prevention of Significant Deterioriation (PSD) Permits Non-Attainment Area Permits What are Federal PSD and Nonattainment NSR Permits? Under Title I of the 1990 Clean Air Act Amendments, there are National Ambient Air Quality Standards (NAAQS) for criteria air pollutants, i.e.: ozone (associated with VOCs and NOx) carbon monoxide (CO) particulate matter (PM10) sulfur oxides (SOx) nitrogen dioxide (NO2) lead The United States is divided into attainment and nonattainment areas for each pollutant with respect to these NAAQS standards. A federal PSD permit may be required for major sources of pollutants in areas which are in attainment of the NAAQS and which meet certain other criteria. The program is designed to maintain good air quality with some allowances for economic growth. A non-attainment NSR permit may be required for major sources of pollutants in nonattainment areas which meet certain other criteria. Emissions increases must be offset and controls must be installed which meet the lowest acheivable emission rates.

About Us Air Primer Contact Us Today’s Business and Air Quality - Managing Economic Growth and Environmental Protection Pollutants and Standards The U.S. Environmental Protection Agency (EPA) has set forth standards for a set of pollutants that it refers to as the criteria pollutants. These standards are referred to as the National Ambient Air Quality Standards (NAAQS) and were promulgated to protect human health and welfare with an adequate margin of safety. The criteria pollutants include: • Carbon Monoxide (CO) • Nitrogen Dioxide (NO2) • Ozone (O3) • Lead • Particulate Matter less than 10 microns aerodynamic diameter (PM10) • Particulate Matter less than 2.5 microns aerodynamic diameter (PM2.5) • Sulfur Dioxide (SO2) For more information about the National Ambient Air Quality Standards (NAAQS): NAAQS Table Geographic areas where air quality complies with the NAAQS are referred to as Attainment Areas. There are many areas across the country where air quality does not comply with the NAAQS for one or more of the criteria pollutants. These regions are called Nonattainment Areas. For more information about the Nonattainment Areas in New England: Nonattainment Areas in New England Air Quality Regulations and Permitting Air Quality Impact Modeling For many facilities, a critical step in the permitting process is the air quality modeling analysis. These types of analyses use computer models to assess the potential impact of a facility on air quality. These models, which were developed by the EPA, use a complex set of data inputs to predict a conservatively estimated air quality impact for the facility of interest. Inputs to these models include information about the facility itself, representative meteorological data, and the topography of the area surrounding the facility. Using this information, these models predict the expected concentration of the pollutants associated with the operation of the facility in question. Modeled pollutant concentrations are then compared with the NAAQS and/or applicable toxic air pollutant standards.

CleanAir - Services - Air Quality Consulting / Management - Air Dispersion Model Air dispersion modeling can be used to predict the concentration of criteria pollutants at specified groundlevel receptors around an emission source. http://www.cleanair.com/Services/AirQualityConsultingMgt/airdispmod/airdispmodcs

Home Services Equipment Search ... Stack / Source Emissions Testing SEARCH BY Industry Method Air Dispersion Modeling - Case Study Air dispersion modeling can be used to predict the concentration of criteria pollutants at specified ground-level receptors around an emission source. The air quality impact of stationary sources can be estimated using EPA approved air dispersion models. Dispersion models are used to determine concentrations of pollutants generated from Point, Area and Fugitive sources. Fence line monitoring may be required for long term compliance. Some of the various State and Federal regulations that impact the need for Modeling and provide baseline compliance include: 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. Fugitive sources can be modeled for to determine compliance with NSPS or NAAQS.
