Pod Technologies: EDR Trend

Overview:

EDR Trend is a Microsoft® Excel®-based application that summarizes and graphs air pollution emissions and unit operational information from Clean Air Markets Electronic Data Reporting (EDR) files.

Operators of units in Clean Air Markets are required to continuously monitor their air pollution emissions and submit quarterly EDR files to the US EPA. EDR files are publicly available from the Clean Air Markets Web site, the US EPA FTP site, and the National Technical Information Service (NTIS).

Uses for EDR Trend include:

• Characterizing air pollution emissions;
• Reviewing operational trends; and
• Evaluating air pollution control device performance.

Features:

• Reads EDR files available from the Clean Air Markets Web site, US EPA FTP site, NTIS CD-ROMs, or a 40 CFR 75 Continuous Emission Monitoring Systems (CEMS) Data Acquisition and Handling System (DAHS).
• Creates data summaries and graphs of operating time, gross load, gross heat rate, SO2 emissions, and NOx emissions.
• Provides data review options for quarterly, multi-quarter, Ozone Season, or custom time intervals.
• Provides a starting point for further data analysis using Microsoft Excel calculation and graphing capabilities.
• Exports Comma Separated Variable (CSV) text files of hourly data for use by other software.
• Software and workbook template can be modified for added features.

EDR Trend Details

Software:

Note: Beginning with the first quarter of 2009, a new XML-based (eXtensible Markup Language) data format will replace the text-based EDR format (EDR versions 2.1/2.2). As a result, the current versions of EDR Trend will no longer be able to read data from the Acid Rain and CAIR Programs after 4h Quarter 2008 (however, previous data will be available in EDR format). A new program is under development to support this change.

EDR-XML 1.0

Note: US EPA modified their Clean Air Markets Web site. EDR data are now available from Emissions Data Prepackaged Data Sets or the US EPA FTP site in ZIP archives. An updated version of EDR Trend is available that incorporates these changes.
