Section 516.52 Continued.
(a) Ground water.
(1) Ground water levels, infiltration rates, subsurface flow and stor-
age characteristics, and the quality of ground water shall be monitored
in a manner approved by the regulatory authority, to determine the
effects of surface mining activitea on the recharge capacity of re-
claimed lands and on the quantity and quality of water in ground water
systems in the mine plan and adjacent areas.
(2) When surface mining activities may affect the ground water systems
which serve as aquifers which significantly ensure the hydrologic bal-
ance of water use on or off the mine plan area, ground water levels and
ground water quality shall be periodically monitored. Monitoring shall
include measurements from a sufficient number of wells and mineralogical
and chemical analyses of aquifer, overburden, and spoil that are ade-
quate to reflect changes in ground water quantity and quality resulting
• from those activities. Monitoring shall be adequate to plan for modi-
fication of surface mining activities, if necessary, to minimize dis-
turbance of the prevailing hydrologic balance.
(3) As specified and approved by the regulatory authority, the person
who conducts surface mining activities shall conduct additional hydro-
logic tests, including drilling, infiltration tests, and aquifer tests
and shall submit the results to the regulatory authority, to demonstrate
compliance with Sections 816.50-816.52.
The coal aquifer in the undeveloped, poorly permeable Coalmont
Formation does not significantly affect the hydrologic balance
within or adjacent to the Mine Plan Area, and is not essential to
the proposed postmining land use. See Section 780.21.
The ground water monitoring program described at Section 780.21 (b)
• will be used to observe ground water levels, recharge and discharge
