Investigators: EPA Had No Rules For Working At Risky Mines

DENVER (AP) — Government investigators say the U.S. Environmental Protection Agency had no rules for working around old mines when the agency inadvertently triggered a massive spill from a Colorado mine that polluted rivers in three states.
The EPA’s Office of Inspector General said Monday the agency started work on safety standards after the spill and expects to release them this week.(credit: CBS)
