Using EPA Continuous Emissions Monitoring Systems (CEMS) database to present the emissions from power plants in the western United States.

This project used data from the US Environment Protection Agency’s (EPA) Continuous Emissions Monitoring Systems (CEMS) database to present the emissions from power plants in the western United States. The data is delivered as a KML File that can viewed using Google Earth.

To load a KML file in Google Earth, click on the Project icon in the left pane. Then click on “New Project” and choose “Import KML file from computer”. Choose the KML file and begin browsing the power plant emissions data by state or by plant.
