Friday, October 23, 2015 NATION/WORLD Probe ¿nds EPA error caused mine spill Facing GOP queries, Clinton Page 8A East Oregonian BILLINGS, Mont. (AP) — Government investigators squarely blamed the U.S. Environmental Protection Agency on Thursday for a 3 million-gallon wastewater spill from a Colorado gold mine, saying an EPA cleanup crew rushed its work and failed to consider the complex engineering involved, triggering the very blowout it hoped to avoid. The spill that fouled rivers in three states would have been avoided had the EPA team checked on water levels inside the Gold King Mine before digging into a collapsed and leaking mine entrance, Interior Department investigators concluded. The technical report on the causes of the Aug. 5 spill has implications across the United States, where similar disasters could lurk among an estimated hundreds of thousands of abandoned mines that have yet to be cleaned up. The total cost of containing this mining industry mess could top $50 billion, according to govern- ment estimates. The root causes of the Colorado accident began decades ago, when mining companies altered the Àow of water through a series of interconnected tunnels in the extensively mined Upper Animas River watershed, the seeks to close book on Benghazi Associated Press AP Photo/Brennan Linsley, file In this Aug. 12 file photo, water flows through a se- ries of retention ponds built to contain and filter out heavy metals and chemicals from the Gold King mine chemical accident, in the spillway about 1/4 mile downstream from the mine, outside Silverton, Colo. report says. EPA documents show its of¿cials knew of the potential for a major blowout from the Gold King Mine near Silverton as early as June 2014. After the spill, EPA of¿cials described the blowout as “likely inevi- table” because millions of gallons of pressurized water had been bottling up inside the mine. The Interior report directly refutes that assertion. It says the cleanup team could have used a drill rig to bore into the mine tunnel from above, safely gauging the danger of a blowout and planning the excavation accordingly. Instead, the EPA crew, with the agreement of Colorado mining of¿cials, assumed the mine was only partially inundated. “This error resulted in development of a plan to open the mine in a manner that appeared to guard against blowout, but instead led directly to the failure,” according to engineers from Interior’s Bureau of Reclamation, who spent two months evaluating the accident. The blowout tainted rivers in Colorado, Utah, New Mexico, and on the Navajo Nation with dangerous heavy metals including arsenic. Nurse quarantined over Ebola fears sues Gov. Christie TRENTON, N.J.
