Total Toxic Releases
Units: Lbs
To account for the amount of chemicals released into the environment, the Total Toxic Releases variable was selected to evaluate facilities because specific toxic releases can have significant environmental and public health effects, especially if they are released in extremely large quantities. This variable includes on- and off-site releases from production to air, water, land, Class I underground injection wells, Resource Conservation and Recovery Act (RCRA) Subtitle C landfills, and other landfills. It excludes toxic releases due to catastrophic, one-time events so that toxic releases related to facility production processes are only considered.
