Section 88.58. Disposal of excess spoil

(a) The reclamation plan shall contain a description, including appropriate maps and cross sections, of the proposed disposal site and design of the spoil disposal structure. The description shall include the geotechnical investigation, design, construction, operation, maintenance and removal, if appropriate, of the site and structures.

(b) When excess spoil will not be used to reclaim nearby abandoned surface mines, the geotechnical investigation of the proposed disposal site shall include the following:

(1) The character of bedrock and any adverse geologic condition in the disposal area.

(2) A survey identifying all springs, seepage and groundwater flow observed or anticipated during wet periods in the area of the disposal site.

(3) A survey of the potential effects of subsidence of the subsurface strata due to past and future mining operations.

(4) A stability analysis, including, but not limited to, strength parameters and long-term seepage conditions. These data shall be accompanied by a description of all engineering design assumptions and calculations and the alternatives considered in selecting the specific design specifications and methods.

The provisions of this § 88.58 adopted December 19, 1980, 10 Pa.B. 4789, effective July 31, 1982, 12 Pa.B. 2382.
