In earlier posts we have noted concerns regarding the hydraulic fracturing of natural gas wells and the potential for its regulation. Legislation has been introduced in Congress to repeal the exemption for hydraulic fracturing under the SWDA, and referred to the House Committee on Energy and Commerce. More from the Star-Telegram: "A study by the Environmental Protection Agency determined that hydraulic fracturing posed little risk to water. Environmentalists say that the study is flawed and that the exemption poses health risks." Not a bad article overall.
