Ch. 481

LAWS OF MARYLAND

[(e)] (F) A permit issued under this subtitle is valid for
a period of up to five years from its issuance or until the
operation is completed or abandoned, unless the Department
suspends or revokes the permit or unless the permittee requests a
change in operations.

[(f)] (G) A permit is renewable on application and payment
of a $200 fee.

[(g)] (H) A permit may not be issued to any operator for
the purpose of mining any abandoned mine or part of it that has
been sealed in compliance with this subtitle, unless a detailed
projected mining plan in the form of a cost-benefit analysis is
submitted to and approved by the Secretary. The Secretary may not
approve a plan unless the plan shows that a continuation of
mining would not affect adversely the current environmental
balance of the area and would be advantageous for the more
complete recovery and utilization of the natural resources.

[(h)] (I) The operator of any coal mine in the State shall
make, or cause to be made by a competent mining engineer or
surveyor, an accurate map of the mine for each seam of coal
worked, on a scale of not less than 200 feet to the inch, which
shows:

(1)  The boundary lines of the property, the location
of all buildings, railway tracks, wagon or other roads, rivers,
streams, lakes and ponds, with the depth indicated, other
important landmarks on the surface of the property; connecting
lines of contiguous properties; and any lines with relation to
contiguous mines or coal properties.

(2)  The openings, excavations, shafts, slopes,
drifts, tunnels, planes, entries, rooms, crosscuts, and the name
and location number of each coal mine, if so identified.

(3)  The elevation datum at top and bottom of each
shaft, slope, and any drifts, tunnels, planes, at the faces of
entries, as found at each semiannual survey; and in rooms and
entries adjacent to boundary lines between the mine and any
adjoining mine at points not more than 300 feet apart; the date
of entry of each datum; and the location and elevation of any
body of water dammed within or held back in any portion of the
mine, giving as nearly as ascertainable, the true area of the
body of water.

(4)  The direction of the air currents in the mine,
indicated by arrows.
