Control Strategy Tool
The Control Strategy Tool (CoST) is a client-server system and is part of EPA's Emissions Modeling Framework (EMF). The purpose of CoST is to model the emission reductions and engineering costs associated with control strategies applied to point, area, and mobile sources of air pollutant emissions to support the analyses of air pollution policies and regulations. CoST accomplishes this by matching control measures to emission sources using algorithms such as "maximum emissions reduction" and "least cost". Control strategy results can be exported to CSV files or viewed in a graphical table that supports sorting, filtering, and plotting. The results can also be merged with the original inventory to create controlled emissions inventories that can be exported to the emissions model SMOKE.
The Control Strategy Tool was developed as a replacement for the AirControlNET (ACN) software tool which is no longer supported by EPA. It was determined in 2006 that it was an appropriate time to replace the ACN software with newer software that could provide improved functionality and transparency to support current and upcoming needs. A prototype version of the Control Strategy Tool was developed in 2006 and a fully functional version was developed in 2008. The tool has the functionality of AirControlNET but with added capabilities, including:
- the ability to insert emissions inventories almost seamlessly from the Emissions Modeling Framework (EMF)
- the ability to insert new control measure data
- easier for users to track their analyses and create summary reports and output files
- Quality assurance (QA) steps provided for identifying errors in emissions and control measure data
Information on control efficiencies and costs is contained in the Control Measure Database (CMDB). This database currently focuses on criteria pollutants.
The CoST software (version 2.11.1) is available for download (see below). Note that because of resource limitations, EPA is not able to provide any support for the installation or operation of CoST outside of the Agency. Documentation for the tool is included on this web site (below). Contact David Misenheimer at 919-541-5473 or at email@example.com for general information about CoST.
Access to the CoST Software and User's Guide
EPA's Control Strategy Tool (CoST) version 2.11.1 is available on the Community Modeling and Analysis System (CMAS) website at the link below. From the CMAS website you can access both the Java code that is used to build the server and client applications, and files with SQL statements to create and update the database tables and stored procedures.
The CoST Training Manual serves as a User's Guide and contains installation instructions. A link to the CoST Training Manual is listed below under the "Tool Documentation and Data" heading.
See the links below for other CoST documentation and control measure information.
