west of the helipad and topsoil pile (Figure 2). This area was reclaimed during
the 2000 - 2001 reporting period as described in Section 4.0,
3.3 Solution Mining Wells and Pads
American Soda constructed 34 well pads in the summer of 2000. The size of
each pad is approximately 150 feet by 80 feet, plus cut and fill slopes. Total
disturbance associated with construction of the 34 well pads is approximately 15
acres,
Out of the 34 pads constructed, 24 wells were actually drilled and completed
during the summer and fall of 2000. Two wells formerly part of the American
Soda'sTest Mine Facility were also converted to commercial wells and brought
on-line. Drilling of new wells commenced in July 2000 and was completed in
November 2000. One new well was drilled on an existing well pad and placed in
operation in during the 2001 - 2002 reporting year. Three new wells were drilled
on existing well pads and placed in operation during the 2002 - 2003 reporting
year.
There were no new areas of disturbance on the Yankee Gulch Sodium Minerals
Project properties during the 2002 - 2003 reporting year,
^ 3.4 Well Field Piping and Pump Stations
There are three types of well field piping utilized by the Yankee Gulch Project.
They include the 12-inch diameter main header pipe rack, which extends from
the Piceance Site Processing Facility down the length of the 0 - 5 year mining
panel; numerous 8-inch lateral pipelines to serve groups of solution mining wells;
and 4-inch individual well pipelines, Two pump stations have been constructed
' in the well field to liff nahcolite solution from the well field to the Piceance Site
Processing Facility. Figure 3 provides a detailed map of the well field layout,
including the well field piping and pump station configuration. Total disturbance
~ associated with well field piping and pump houses is approximately 8.8 acres,
3.5 Well Field Roads
Access through the Well Field is provided by the Well Field Access Road that
extends from the Main Access Road down to the Test Mine Area below (Figure
3). This road was constructed in January and February 2000 and resulted in
disturbance of approximately 9.8 acres. Individual well pads are served by
narrow one-lane roads, It is estimated that construction of these well pad roads
has resulted in the disturbance of approximately 8 additional acres.
