EPA inspector general begins investigation into mine spill

The Environmental Protection Agency’s Office of Inspector General (OIG) said Monday it will begin investigation the Aug. 5 incident that sent 3 million gallons of toxic sludge into Colorado’s Animas River. 

In a memo to EPA officials, Assistant Inspector General Carolyn Copper said her office would request documents and interview staffers at both the EPA’s Washington headquarters and its regional offices during the investigation.

The focus, she said, will be the “cause of, and the EPA’s response to,” the spill at the shuttered Gold King Mine in Silverton, Colo.

“Due to the scope of the issues involved, the OIG’s Office of Program Evaluation, Office of Audit and Office of Investigations will work collaboratively to conduct parts of this review,” Copper wrote in a memo to the regional administrator covering the Colorado area and an official in the EPA’s Office of Solid Waste and Emergency Response.

“Your offices may receive joint OIG office requests for meetings and information, as well as individual OIG office requests for meetings and information.“

A team of EPA contractors was inspecting the Gold King Mine on Aug. 5 when they inadvertently sent a flood of contaminated chemicals, including lead, arsenic and other heavy metals, into the Animas River.

The incident is likely to draw attention from more than just the inspector general and the oversight panel.
