On pages 41.1 and 41.2 of the amended Appendix 4.5-1, the consultant
describes a proposed visual monitoring program which will specifically
observe slope characteristics considered indicative of slope movement,
such as .surface cracking, movement of large rock blocks and the
development of bulging ground near the base of the slope." The amended
application's Appendix 4.5-1 also presents a detailed proposed program
for mitigation of slope stability problems. Simplistically, in areas
where no danger is presented to structures, mine personnel or the
public, the applicant proposes to restrict access and visually observe
manifested slope instabiiity phenomena. In any areas where a hazard
exists to structures, mine personnel or the public, the operator will
also, "... as necessary and appropriate, provide slope stabilization
techniques". As amended, however, vagueness exists concerning the role
of the Division in the decision of whether or not a hazard to
structures, mine personnel or the public exists. To avoid possible
future disagreement, our eventual findings will impose a stipulation
which clearly states that the Division shall review and concur with any
decision of whether a hazard is represented by any specific slope
movement event and whether a slope stabilization program should be
developed and implemented.
(4) 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, our eventual findings will include a stipulation
requiring the submission of a proposed subsidence report format within
six months following issuance of the permit.
