9.05.11 Groundwater Protection
As noted earlier in Section 2.04.7, there is no presence of any
groundwater in or above the area to be mined by the underground
operations other than perched systems which exhibit little lateral or
vertical continuity. Likewise, no acid-forming or toxic-forming
materials have been found to exist in the overburden or underburden of
the C-Seam or B-Seam Coal.
4.05.12 Protection of Groundwater Recharge Capacity
The reclamation plan, as described in Section 2.05.4, will return the
disturbed land to approximately the pre-mining condition; therefore,
groundwater recharge capability is expected to remain essentially the
same as the pre-mining condition. Also, because of the minimal existence
of groundwater in the permit area, the mining operation and subsequent
reclamation and sealing of the portals should have no adverse affect on
the existing groundwater recharge capabilities found in the area.
4.05.13 Surface and Groundwater Monitoring
The Operator will monitor groundwater as outlined in Section
2.04.7(1)(v). The current ground water monitoring plan is presented on
page 2.04-30b.
Stipulation No. 4 to the permit states:
THE APPLICANT SHALL CONTINUE TO SUBMIT TO THE DIVISION AN
ANNUAL REPORT OF INFLOWS, DISCHARGES AND CONSUMPTION OF WATER
WITHIN THE MINE. THIS REPORT WILL INCLUDE A MINE WORRINGS MAP
WHICH SHALL CONTAIN THE SOURCE (I.E., FAULT, FRACTURES, ETC.),
QUANTITY, DURATION, AND QUALITY OF MINE INFLOWS, AND A TABLE
CONTAINING RECORDS OF WATER DISCHARGED FROM THE MINE, CONSUMED
IN THE MINE AND IMPORTED FOR USE WITHIN THE MINE WILL ALSO BE
INCLUDED.
The requirement in Stipulation No. 4 to submit a mine workings map is
hereby revised as follows:
A MINE WORKINGS MAP SHALL ONLY BE REQUIRED IF THERE ARE
MEASURABLE INFLOWS TO THE MINE DURING THE YEAR. ALL OF THE
INFORMATION REQUIRED BY STIPULATION NO. 4 SHALL BE SUBMITTED
WITH THE ANNUAL HYDROLOGIC REPORT.
A new Stipulation No. 32 is to be added to the permit which will
incorporate the revised Stipulation No. 4 language. Stipulation No. 4
will be deleted from the permit as a result of the addition of
Stipulation No. 32.
The planned surface water monitoring plan includes monitoring required
under an NPDES Permit which was issued by the Colorado Department of
Health. Surface water monitoring locations are shown of the Mine
Facilities Map, (Map 10). Surface water samples will be analyzed for pH,
