A coalition of environmental groups has asked the U.S. Environmental Protection Agency to subject oil and gas extracting companies to the same emissions oversight as other energy industry sectors. The Environmental Integrity Project, the lead organization behind the request, says companies, especially those that conduct natural gas fracking, should have to report their emissions to the Toxic Release Inventory, or TRI. In a statement, the group said: “Despite the many indications of the toxicity of the chemicals used in shale oil and gas removal, the extraction industry is one of the few within the energy sector that does not report to the TRI.” The request comes on the heels of recent studies alleging increased health risks in communities exposed to fracking. A survey by Earthworks of residents in 14 Pennsylvania counties found that fracking has led to an 80 percent increase in sinus problems and 70 percent increase in throat irritation. A recent U.S. Geological Survey study in Wyoming found that fracking chemicals have again been found in the groundwater of the town of Pavilion, affirming the conclusion of an EPA study last year.
