PITTSBURGH -- The largest Marcellus Shale industry group in Pennsylvania says its members will voluntarily disclose chemicals used in each natural gas well as of Jan. 1.
The Marcellus Shale Coalition says in a statement issued Thursday that its members want to go beyond state requirements and reassure people who have questions. Members will list the chemicals used in each well on the website FracFocus.org. The group says many companies are already doing so.
The environmental group PennFuture says it applauds the move, but that the state still needs to pass a law making disclosure mandatory for all companies, not just members of the coalition.
The drillers use water, sand and a small amount of chemicals to break apart shale rock formations deep underground. That frees the gas trapped in the rocks.
