EPA chief: Agency did not shirk responsibility in mine spill

WASHINGTON (AP) – The head of the Environmental Protection Agency dismissed complaints Wednesday by Republican lawmakers that her agency downplayed the seriousness of a toxic mine spill that fouled rivers in three Western states.

EPA Administrator Gina McCarthy called the spill caused by her agency “tragic and unfortunate” and said the EPA has taken responsibility to ensure that 3 million gallons of rust-colored sludge released into Colorado’s Animas River is cleaned up. The Aug. 5 spill occurred during excavation work at an inactive gold mine near Silverton, Colorado.

Republican senators charged at a hearing Wednesday that EPA is treating itself more gingerly than if a private company were responsible for the spill, which sent lead, arsenic and other heavy metals rushing toward downstream communities. The spill contaminated rivers in Colorado, New Mexico and Utah, as well as in the Navajo Nation and Southern Ute Reservation.

Sen. John Boozman, R-Ark., said the EPA employed a “double standard” in responding to the Colorado spill. While the agency at times adopts an aggressive, even “heavy-handed” approach to regulating companies, Boozman told McCarthy, “your initial reaction (to the Colorado spill) was to downplay the severity of it.”

Boozman said he was appalled at McCarthy’s comment, during an Aug. 13 visit to New Mexico, that the Animas River was “restoring itself.”
