Notes:
1. Parameters monitored as a result of PR-10
2. Added to baseline analyses in 1996. Not for analyses completed prior to 1996.
3. All arameters will be analyzed for their dissolved form unless stated otherwise.
3.1 Surface Water Monitoring
The West Elk Mine is drained to the north by the North Fork, to the south by Minnesota Creek, to
the west by Gribble Gulch, and to the east by Deep Creek. The surface water monitoring system
for the Project includes 23 stream stations, comprised of 10 sites with continuous recording devices
and 13 sites with instantaneous flow measuring devices.
In WY 2006 two new monitoring stations, Deep Creek Ditch and Minnesota Reservoir Flume,
were added to the monitoring program in order to provide baseline monitoring data in anticipation
of the Project's potential future plans for the longwall mining in the South of the Divide permit
