The Environmental Protection Agency says it expects to give La Plata County and the Southern Ute tribe more time to work out an agreement with the agency for compensation for their costs from the Gold King Mine spill.
The EPA said in a written statement Monday a 180-day extension will likely be granted this week. The deadline is Tuesday.
The county and the tribe said last week that EPA headquarters in Washington hadn't responded to multiple requests for an extension.
Sens. Michael Bennet and Cory Gardner and Rep. Scott Tipton asked the EPA to make sure local governments and tribes are fully reimbursed.
An EPA-led crew inadvertently released 3 million gallons of wastewater tainted with heavy metals from the mine in August. Colorado, New Mexico and Utah rivers were affected.
