mine block will proceed underground in a southerly direction
from the portal o! Applicant's Mt. Gunnison No. 1 Mine, which
portal is located on the south side of the North Fork
Gunnison River as tollows:
804.81 feet South of the North line and 1406.25
feet West of the Eaet line of Section 16,
Township 13 South, Range 90 West of the 6th Prime
Meridian.
6. Mining will, as pertinent to this plan for
augmentation, extract coal beneath the natural basins
of the following natural and Intermittent streams:
a. the Dry Fork of Minnesota Creek, and its
tributaries; and
b. Lick Creek, __

both of which are tributaries of Minnesota Creek, a tributary
of the North'Fork Gunnison River.
7. Applicant will conduct primary or developmental
mining of the mine block, and secondary or retreat mining
activities. The term "retreat mining," for purposes of this
judgment and decree, means secondary mining, occurring (as to
a. given area of the mine) after primary or developmental
mining, during the course of which a percentage of the
supporting pillars left during developmental mining are
removed. There is a potential that land subsidence and
fracturing of the overburden will follow retreat.mininq
activity. Subsidence, should it occur, could cause reduc-
tions in stream flow in the above-named streams through, for
example, seepage of surface water into a subsidence crack.
8. In order to avoid such reduction, or to cure it
should it occur, Applicant adogted, in the course of the
permitting process for its mine, a Plan for Protection of
Minnesota Creek Water Supplies (hereinafter protection plan),
attached as Exhibit 1. IInder that protection plan, or any
amendment thereto, should a loss of surface water occur as a
result of retreat mining, Applicant may cure-that loss in
one or more of the following ways:
(a) if the source of surface water loss is readily
observable, Applicant will culvert the surface flow across
the point of leakage, a technique that may also be used as a
follow-up to the measure identified in (b) below;
(b) if the source of water loss is not readily identi-
fiable but a water loss 1s indicated by monitoring, and
water is accruing to the mine drifts, Applicant-will drill
