disturbance to the hydrologic balance.
Discussion of the PHC begins on page 125 of Section
2.05.6(3)(b)(iv) of permit C-1981-038 and is divided into four
sections; effects to surface water from mine facilities, effects
to groundwater from mine facilities, effects to groundwater
within the permit and adjacent areas, and effects to surface
water within the permit and adjacent areas.

The water quality reported for a majority of surface water
sites fell within the baseline ranges. Higher than average
parameters were identified both at sites affected by mining
and those not affected by mining. See Table 2 below.
