BONDING ADJUSTMENT SCHEDULE for TR-47
Transfer of Bonding for Coal Exploration Approved by Permit Revisions to Exploration Permits
Retention of Surface Facilities for Post Mining Land Use
Since the Golden Eagle Mine received a mining permit in 1981 numerous coal exploration activities have
been permitted though the permit revision process and as Notices of Intent to Conduct Coal Exploration
(NOIs). The conduct of these activities have been similaz: locations remote from mine facilities,
disturbance limited to the area required by an exploration drill rig, and where possible, use ofpre-existing
access roads, or roads to be retained for an approved post-mining land use.
The majority of these sites were reclaimed subsequent to the completion of drilling. In a few cases, holes
were cased for either water monitoring wells, or for methane liberation. All known sites were checked by
Basin personnel to evaluate the success of the reclamation efforts in 1996, and where necessary additional
reclamation activities were undertaken. Roads inappropriate for post mining land use were reclaimed.
Roads to be retained were water-barred to minimize the potential for erosion.
Water Monitoring wells, not requved for evaluating the impacts of past mining during the fmal reclamation
process (TR-44), were properly abandoned in accordance with the approved reclamation plan for each site.
Twenty-seven wells completed for methane liberation were later permitted for post mining industrial use
for the commercial production of methane (TR-45). These sites are included in this discussion for
• completeness only, and are not affected by this revision.
Bonded Activities not implemented.
Two permitted activities were not implemented (MR-22 & MR-76). MR-22 was a 1991 exploration
program that was canceled after the acquisition of Wyoming Fuel Company by Entech. MR-76 was for a
communications borehole that was canceled with the announcement of mine closure.
Two permitted activities were also bonded by other revisions. MR-47 by MR-63: Exploration drill hole
GE-6 was permitted by MR-47, but was not drilled. It was later drilled under MR-63 as a methane
liberation well. The bond amount in MR-63 was addressed by TR-45; but the bonding in MR-47 was not
addressed. Similarly, MR-68 for a methane liberation well was also bonded by MR-3l. The MR-31 bond
amount was addressed by TR-45, but MR-68 bonding was over-looked.
Other permit actions approved exploration drilling that was only partially implemented:
• TR-28 - Received approval for eleven (I I) sites. Five (5) sites were not constructed.
Furthermore, four (4) of the completed sites were also banded under NOI CX-92-213-02.
• TR-29 - Included three (3) sites that were not constructed. However, the full bond amount
was addressed in TR-45 (and no action is required by this revision).
• MR-11 & MR-IS -Each included one (I) hole that was not constructed.
• MR-21 -Five (5) of eleven (I I) sites were not constructed.
As shown by Table 28, The "Unused Bond Amount" for these activities totals $179,970. The approval for
these activities is rescinded and the Golden Eagle Reclamation bond requirement reduced by $179,970.
