WASHINGTON (AP) – The Senate Indian Affairs Committee has issued a subpoena to force the Environmental Protection Agency to testify at a field hearing on a Colorado mine spill that fouled rivers in the West last summer.
Republican Sen. John Barrasso of Wyoming and Democrat Jon Tester of Montana approved the subpoena on Wednesday. The document orders EPA Administrator Gina McCarthy or assistant administrator Mathy Stanislaus to testify at the April 22 hearing in Phoenix.
Barrasso and other Republicans had threatened to force McCarthy to testify, but backed down after the EPA said it will make Stanislaus and another high-ranking official available.
Barrasso chairs the Indian Affairs panel, while Tester is the senior Democrat. The committee is investigating a 3 million gallon spill at Colorado’s abandoned Gold King Mine.
