Meet the requirements of 405 KAR 16:070, Section 1(1)(g); and(c)
Minimize erosion to the extent possible.(2)
Sediment control measures include practices carried out within and adjacent to the disturbed area. The sediment storage capacity of measures in and downstream from the disturbed areas shall reflect the degree to which successful mining and reclamation techniques are applied to reduce erosion and control sediment. Sediment control measures consist of the utilization of proper mining and reclamation methods and sediment control practices, singly or in combination. Sediment control methods include:(a)
Disturbing the smallest practicable area at any one (1) time during the mining operation through progressive backfilling, grading and prompt revegetation as required in 405 KAR 16:200, Section 1(2);(b)
Stabilizing the backfilled material to promote a reduction in the rate and volume of run-off, in accordance with the requirements of 405 KAR 16:190;(c)
Retaining sediment within disturbed areas;(d)
Diverting run-off away from disturbed areas;(e)
Diverting run-off using protected channels or pipes through disturbed areas so as not to cause additional erosion;(f)
Using straw dikes, riprap, check dams, mulches, vegetative sediment filters, dugout ponds, and other measures that reduce overland flow velocity, reduce run-off volume, or trap sediment; and(g)
Treating with chemicals; and(h)
Using sedimentation ponds as required in 405 KAR 16:070.Section 3.
Discharge Structures. Discharge from sedimentation ponds, permanent and temporary impoundments, coal processing waste dams and embankments, and diversions shall be controlled, by energy dissipators, riprap channels, and other devices, where necessary, to reduce erosion, to prevent deepening or enlargement of stream channels, and to minimize disturbance of the hydrologic balance. Discharge structures shall be designed according to standard engineering design procedures.Section 4.
Acid-forming and Toxic-forming Materials. Acid drainage and toxic drainage shall be avoided by:(1)
Identifying, burying, and treating, in accordance with 405 KAR 16:190, Section 3, materials which may adversely affect water quality, or be detrimental to vegetation or to public health and safety if not buried and treated;(2)

Burying or otherwise treating all acid-forming or toxic-forming spoil within thirty (30) days after it is first exposed on the mine site, or within a lesser period required by the cabinet. Temporary storage of the spoil may be approved by the cabinet upon a finding that burial or treatment within thirty (30) days is not feasible and will not result in any material risk of water pollution or other environmental damage. Storage shall be limited to the period until burial or treatment first becomes feasible. Acid-forming or toxic-forming spoil to be stored shall be placed on impermeable material and protected from erosion and contact with surface water.Section 5.
Groundwater Protection and Recharge Capacity. In order to protect the hydrologic balance, surface mining activities shall be conducted according to 405 KAR 8:030, Section 32(1) and (2) and the following:(1)
Groundwater quality shall be protected by handling earth materials and run-off in a manner that minimizes acidic, toxic, or other harmful infiltration to groundwater systems and by managing excavations and other disturbances to prevent or control the discharge of pollutants into the groundwater; and(2)
Groundwater quantity shall be protected by handling earth materials and run-off in a manner that will restore the approximate premining recharge capacity of the reclaimed area as a whole, excluding coal mine waste disposal areas and excess spoil fills, so as to allow the movement of water to the groundwater system.Section 6.
Surface Water Protection. In order to protect the hydrologic balance, surface mining activities shall be conducted according to 405 KAR 8:030, Section 32(1) and (2) and the following:(1)
Surface water quality shall be protected by handling earth materials, groundwater discharges, and run-off in a manner that:(a)
Minimizes the formation of acidic or toxic drainage;(b)
Prevents, to the extent possible using the best technology currently available, additional contribution of suspended solids to stream flow outside the permit area; and(c)
Will not cause or contribute to a violation of any federal or state effluent limitations or water quality standards.(2)
If drainage control, restabilization and revegetation of disturbed areas, diversion of run-off, mulching, or other reclamation and remedial practices are not adequate to meet the requirements of this section and 405 KAR 16:070, the operator shall use and maintain the necessary water-treatment facilities or water quality controls for as long as treatment is required under this chapter; and(3)
Surface water quantity and flow rates shall be protected by handling earth materials and run-off in accordance with the steps outlined in the plan approved under 405 KAR 8:030, Section 32(1) and (2).Section 7.

The permittee or operator shall promptly replace the water supply of an owner of interest in real property who obtains all or part of his supply of water for domestic, agricultural, industrial, or other legitimate use from an underground or surface source, if the water supply has been adversely impacted by contamination, diminution, or interruption proximately resulting from the surface mining activities. Baseline geologic and hydrologic information required in 405 KAR 8:030, Sections 12 through 16, and other relevant information available to the cabinet, shall be used to determine the impact of mining activities upon the water supply.(2)
If replacement of a water supply is required under subsection (1) of this section the permittee shall:(a)
If the water supply to be replaced is a domestic supply, provide water supply on both a temporary and permanent basis in accordance with this paragraph;1.
Within forty-eight (48) hours after receiving notice from the cabinet that the water supply was adversely impacted by mining, provide drinking water on an emergency basis;2.
Within two (2) weeks after receiving notice from the cabinet that the water supply was adversely impacted by mining, provide a temporary water supply connected to the existing plumbing, if any, that provides water for all ordinary household purposes including drinking, cooking, bathing, sanitation, and laundry, and drinking water for poultry, livestock, and domestic animals, and water for noncommercial domestic agricultural and horticultural activities;3.
Within two (2) years after receiving notice from the cabinet that the water supply was adversely impacted by mining, provide a satisfactory permanent water supply;(b)
If the water supply to be replaced is other than a domestic supply, provide water supply on both a temporary and permanent basis on a schedule established by the cabinet on a case-by-case basis;(c)
Provide water supply equivalent to premining quantity and quality;(d)
Provide an equivalent water delivery system; and(e)
Pay operation and maintenance costs in excess of customary and reasonable delivery costs for the premining water supply for a period of twenty (20) years, or other period agreed to by the permittee and the owner of interest. Upon agreement by the permittee and the owner of interest, the obligation to pay the excess operation and maintenance costs may be satisfied by:1.

A uniform series of payments whose present worth equals or exceeds the present worth of the increased annual operation and maintenance costs for a period of twenty (20) years, or other period agreed to by the permittee and the owner of interest; or3.
Other reasonable compensation arrangements which fairly compensate the owner for the future operation and maintenance costs for a period of twenty (20) years, or other period agreed to by the permittee and the owner of interest.(3)
If the affected water supply was not needed for the land use in existence at the time of loss, contamination, or diminution, and if the supply is not needed to achieve the postmining land use, replacement requirements may be satisfied by demonstrating that a suitable alternative water source is available and could feasibly be developed. If this approach is selected, written concurrence shall be obtained from the owner of interest.(4)
(a)
If contamination, diminution, or interruption to a water supply protected under subsection (1) of this section occurs, the cabinet shall require the permittee to obtain additional performance bond in the amount of the estimated cost to replace the protected water supply, until the replacement is completed. If replacement is completed within ninety (90) days of the occurrence, additional bond shall not be required. The cabinet may extend the ninety (90) day time frame, but not to exceed one (1) year, if the permittee demonstrates and the cabinet finds in writing that not all reasonably anticipated changes affecting the protected water supply have occurred, and that therefore it would be unreasonable to complete the replacement within ninety (90) days.(b)
If the permittee demonstrates that his liability insurance policy under 405 KAR 10:030, Section 4 covers the replacement, the additional bond amount required under paragraph (a) of this subsection may be reduced by the amount of the insurance coverage applicable to the replacement. The existence of applicable insurance coverage shall not prevent forfeiture of a performance bond under 405 KAR 10:050.(c)
The cabinet may promptly release or return the additional bond amount provided under paragraph (a) of this subsection if the cabinet determines, based upon an application and information submitted by the permittee, the cabinet's own investigation as appropriate, and other information available to the cabinet, that the permittee has satisfactorily completed the required replacement.Section 9.
