only one limited set of monuments is considered imprudent. Our eventual
findings should impose a stipulation specifically requiring the installation
of a second analogous set of subsidence monitoring monwnents at another agreed
location on Coal Ridge.
The applicant has amended the application to include a separate letter and
supporting communique from the U.S. Bureau of Mines indicating that a
subsidence research program would be instigated at the Coal Ridge mine, which
would provide supplemental subsidence monitoring facilities. In order to
assure that an adequate subsidence monitoring program is approved and
operational prior to any development within the coal seam, the Division
believes it appropriate to impose the following stipulation upon permit
approval.
STIPULATION:
IF THE U.S. BUREAU OF MINES AND STORM KING MINING HAVE NOT AGREED TO A
SUBSIDENCE MONITORING PROGRAM ACCEPTABLE TO THE DIVISION PRIOR TO COMPLETION
OF THE ROCK TUNNEL, THE DIVISION WILL REQUIRE STORM KING MINING TO AMEND ITS
CURRENT SUBSIDENCE MONITORING PROGRAM. FURTHER, NO MINING SHALL OCCUR WITHIN
THE COAL SEAM UNTIL STORM KING MINING HAS OBTAINED APPROVAL FROM THE DIVISION
FOR THE AMENDED SUBSIDENCE MONITORING PROGRAM.
It will be important to clearly present the results of the visual and survey
monitoring programs at the Coal Ridge No. 1 Mine. The amended application
presents no detail regarding the format of the semi-annual subsidence
monitoring reports. In the interest of facilitating complete and efficient
presentation of the accumulated subsidence monitoring data, the Division
believes it prudent to impose the following stipulation upon the permit
approval.
STIPULATION:
THE DIVISION DIRECTS STORM KING MINING TO PREPARE AND SUBMIT A FORMAT FOR THE
REQUIRED SEMI-ANNUAL SUBSIDENCE MONITORING REPORTS. THIS PROPOSED REPORT
FORMAT SHALL BE SUBMITTED FOR DIVISION REVIEW WITHIN SIX MONTHS FOLLOWING
ISSUANCE OF THE PERMIT. FURTHER, STORM KING SHALL HAVE OBTAINED APPROUAL OF
THE SUBSIDENCE REPORT FORMAT PRIOR TO ANY MINING WITHIN THE COAL SEAM.
Rule 2.06.4 Special Categories of Mining - Steep Slope Mining
Portions of the permit area qualify as steep slope mining areas, exhibiting
slope gradients in excess of 20°. Portions of these steep slope mining areas
will be subsided during the first five year permit period. Based upon the
information contained within the amended application, and assuming the
imposition of the above proposed stipulations, mining operations will comply
with the performance standards contained in Rule 4.27.3. Therefore, the
proposed operations will also conform with the requirements of Rule 2.06.4, as
well. The amended application fulfills the requirements of those sections of
our regulations concerning Steep Slope Mining.
