The Toxics Release Inventory (TRI) is a publicly available database of information on the release and transfer of nearly 650 chemicals by private companies and government facilities. Congress created TRI under the Emergency Planning and Community Right-To-Know Act of 1986 (EPCRA) and the United States Environmental Protection Agency (EPA) administers the program. Electric utilities were added to the list of manufacturing industries required to report to the TRI Program in May 1997.
DTE Energy uses a variety of fuels and energy sources to produce electricity. Five coal-fired power plants produce about 70 percent of the electricity that we supply, with the remainder produced by nuclear power, oil, natural gas, hydro and renewable energy, including wind and solar.
Even with expert operation and sophisticated pollution control equipment, that much coal combustion produces millions of pounds of recycled by-products that are released into the air/water or disposed of in approved containment facilities.
DTE obtains coal from dozens of mines and the coal from each mine has a unique mix of trace elements that are the source for chemicals reported in the TRI data. TRI emissions will vary both year-to-year and from plant-to-plant due to these factors. DTE’s overall TRI emissions have decreased. The graph below illustrates decreasing emissions since 2009.
Based on available studies, DTE is confident its power plant releases are not harmful to employees or the public. DTE commits to operating its power generating stations in compliance with applicable regulatory standards.
