The federal government will pay a Colorado county $2.4 million dollars to help clean up after the Gold King Mine spill.
La Plata County commissioners unanimously agreed to the deal Tuesday.
The U.S. Environmental Protection Agency has assumed responsibility for an August breach at the abandoned mine portal that sent 3 million gallons of mining wastewater into the Animas and San Juan rivers.
EPA officials have until February 1 to sign off on the agreement. The agreement includes eight tasks for ensuring the future health and safety of the county's citizens and environment.
Those include a real-time water monitoring system to alert the county of changes in water quality.
Commissioners postponed until next month a vote on whether to support a Superfund designation.
