a. Please identify separately on the map the areal extent of surface disturbance and
the areal extent of underground mine workings. [2.05.3(2)]
b. Please show details of the underground workings on the map as you have done in
the past for the King I Mine workings. Mine subsidence may cause surface
cracks at the King II Mine. The details of the workings on a map enables
evaluation of subsidence impacts (for example, correlation of surface cracks with
rooms, pillars, and pillar removal). [2.10.3(1)(1)]
c. Please revise the affected area or permit boundary so the affected area does not
extend beyond the permit boundary [1.04(89) and 1.04(7)].
2. Map King II-007.
a. Please revise the third paragraph on page 1 of Section 2.05.3 of the permit
application to accurately indicate which map shows the workings.
3. Appendices 1, 2, and 3 (SEDCAD runs)
a. Please submit revised SEDCAD runs, using the Type II storm applicable to the
area.
