Toxic Release Inventory Data, from 2010. Obtained from this website: http://www.epa.gov/tri/tridata/data/basic/index.html. We have selected only Clackamas, Washinton and Multnomah counties within Oregon. Field names have been changed to comply with GIS standards. We have removed spaces, periods, and moved all numbers to follow text. So the names may appear jumbled. This data can be found on the GIS server at D:\GIS_DATA\ENVSData\Other_Sites\PDX_Metro\Non_RLIS\Pollution\TRI_2010.shp
