Gold Eagle Mining Inc.
Burros Mine Permit Number M- 1977 -297
location at this time. A groundwater monitoring plan will be designed in
accordance with DRMS and CDPHE rules following the lifting of activity
prohibitions by the DOE.
10.0 Surface Water Control and Containment
The Burros Mine has a Colorado Stormwater Discharge General Permit;
Certificate #COR040107. Routine inspections by the operator and DMRS have
not revealed any difficulty as to storm water control. It is understood that the
CDPHE Water Quality Control Division is revising its general Storm Water Permit
for Mining Activities over the next year and a Plan (if necessary) will be
developed in accordance with the requirements of that Permit. Prior to the
resumption of mining activities (currently prohibited by the DOE) facilities
currently in place at the mine site for the containment of surface runoff will be
rehabilitated.
11.0 Surface Water Quality
One perennial stream, the Dolores River, flows past the Burros Mine site. Future
operations at the Burros Mine should have very little effect on surface water
resources. On -site storm -water control structures and best management
practices for any site runoff that may be impacted by mine operations should be
designed to prevent contaminants from entering the Dolores River in
concentrations that exceed the Water Quality Standards for the local Dolores
River Segment number 1.
12.0 Water Quality Monitoring Plan
Due to the ongoing prohibition of activity on DOE Lands monitoring wells have
not been installed at the Burros Mine location. Accordingly, a monitoring plan
will be developed (if necessary) pending the outcome of the ongoing DOE PEIS
process. As discussed in Section 8.0 above, the soil underlying the Burros Mine
site is mudstone and siltstone of the lower portion of the Salt Wash Member of
the Morrison Formation and considered to be impermeable to migration of water
into underlying rock units and groundwater.
In Burro Canyon below the Burros Mine site the ephemeral flow direction is to
the southwest down the steep slopes below the mine permit area and to the
Dolores River. Prior to the resumption of mining activities and after lifting of
activity prohibitions by the DOE a surface water monitoring plan for the Dolores
River will be implemented.
