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 (20-2 and 20-14) formerly part of
the American Soda's Test Mine Facility were also converted to commercial wells
and brought on-line. One well (20-3) was converted to a commercial well but
has never been brought on line. Drilling of new wells (20-11, 20-12, 20-19, 20-30,
20-31, 20-32, 20-33, 20-35, 20-36, 20-74, 21-15, 21-16, 28-17, 28-41, 28-21, 29-34, 29-
29, 29-28, 29-27, 29-26, 29-24, 29-23, 29-22 and 29-20) commenced in July 2000
and was completed in November 2000. One new well (29-68) was drilled on an
existing well pad and placed in operation in during the 2001 - 2002 reporting
year. Three new wells (20-76, 29-53 and 20-76) were drilled on existing well pads
and placed in operation during the 2002 - 2003 reporting year. Drilling of well 29-
51 was started during the 2002 - 2003 reporting year but the drilling operation
was halted due to budget restraints at a depth of 200 feet.
Wells 20-2, 20-3, 20-11, 20-14, 21-15, 21-16, 28-17, 28-41 and 29-51 were Plugged
and Abandoned and Well 20-12 was converted to a Subsidence Monitoring
Well during the 2003 - 2004 reporting year.
There were no new areas of disturbance on the Yankee Gulch Sodium Minerals
Project properties during the 2003 - 2004 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 lift 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.
