FETS Web - Emissions Compliance Assurance Monitoring Model

FETS Web performs continuous air dispersion modeling runs to project the most probable outcomes for a collection of user-defined operating scenarios. This involves using forecast meteorology data and real-time data from monitoring stations as input to an air dispersion model which calculates the expected concentrations of a pollutant based on source parameters and emission properties.

FETS Web meets and surpasses compliance certification requirements of the Part 70 Operating Permits Program and Title VII of the 1990 Clean Air Act Amendments. Most facilities have a monitoring station that can cost roughly 80,000 per year to operate. Stations usually miss the emissions that pass it and once it actually registers a hit, it becomes a painstaking process to determine the origins of the pollutant. FETS Web saves on monitoring station operating costs and provides precise results about emissions from your facility.

Avoid these questions with FETS Web. FETS Web enables you to accurately determine attribution and accountability without hesitation.

FETS Web is a highly customizable software package that can be adapted to the specific needs of your organization. This system uses your site’s emissions sources, monitors, emission information, and other site details. Our graphical interface can be tailored to include displays that suit whatever requirements you might have for control room operators, engineers, modeling specialists, or other users.

Real-Time Modeling

CALPUFF air dispersion modeling can be performed every five minutes to forecast the likely impact of an emergency release at any point. This dynamic modeling combines real-time monitor data from sources, meteorology stations, etc. with available meteorological forecast data.

Integrated CALPUFF Air Dispersion Modeling

Model scenarios, model results, source parameters and other elements of CALPUFF modeling are all stored in the system database, avoiding the problem of constantly importing and exporting files for modeling in a seperate application. Support is also available for the SCIPUFF model.

Dynamic Alert System

FETS Web contains a customizable alert system that will broadcast warnings to your operators, engineers and scientists when certain conditions are observed and predicted. The alerts can be for measured exceedances at a monitoring station, exceedances predicted by modeling, or gaps in real-time data.

Graphical Display

FETS Web visually presents the projected path of the emission plume over your site area, using quality maps for your region. The interface allows you to zoom to specific areas of your site, view concentration impact contours, turn layers on and off, and more.

Presentation of Results

A collection of tools are available to the user for viewing model results. In addition to plume visible in the main graphical display, an extensive collection of data tables, reports, contribution plots and more provide many useful ways for the user to view and interpret the real-time data and modeling results.

Highly Customizable

The FETS Web system is highly customizable. The alert criteria and presentation, graphical display for results, air dispersion model, model scenarios and much more can all be configured to meet the particular needs of the user.
