Section 4VAC25-130-817.81 - Coal mine waste; general requirements(a) General. All coal mine waste disposed of in an area other than the mine workings or excavations shall be placed in new or existing disposal areas within a permit area, which are approved by the division for this purpose. Coal mine waste shall be hauled or conveyed and placed for final placement in a controlled manner to- (1) Minimize adverse effects of leachate and surface-water runoff on surface and ground water quality and quantity;(2) Ensure mass stability and prevent mass movement during and after construction;(3) Ensure that the final disposal facility is suitable for reclamation and revegetation compatible with the natural surroundings and the approved postmining land use;(4) Not create a public hazard; and(b) Waste from other areas. Coal mine waste materials from activities located outside a permit area may be disposed of in the permit area only if approved by the division. Approval shall be based upon a showing that such disposal will be in accordance with the standards of this section.(c) Design certification. (1) The disposal facility shall be designed using current, prudent engineering practices and any criteria established by the division as necessary to achieve the standards of this Part. A qualified registered professional engineer, experienced in the design of similar earth and waste structures, shall certify the design of the disposal facility.(2) The disposal facility shall be designed to attain a minimum long-term static safety factor of 1.5. The foundation and abutments must be stable under all conditions of construction.(d) Foundation. Sufficient foundation investigations, as well as any necessary laboratory testing of foundation material, shall be performed in order to determine the design requirements for foundation stability. The analyses of the foundation conditions shall take into consideration the effect of underground mine workings, if any, upon the stability of the disposal facility.(e) Emergency procedures. If any examination or inspection discloses that a potential hazard exists, the division shall be informed promptly of the finding and of the emergency procedures formulated for public protection and remedial action. If adequate procedures cannot be formulated or implemented, the division shall be notified immediately. Notification shall be by the fastest available means and followed in writing. The division shall then notify the appropriate agencies that other emergency procedures are required to protect the public.(f) Underground disposal. Coal mine waste may be disposed of in underground mine workings, but only in accordance with a plan approved by the division and MSHA under 4VAC25-130-784.25.4 Va. Admin. Code § 25-130-817.81
