(3) The applicant shall describe the source of the hydraulic transport mediums, method of dewatering the placed backfill, retainment of water underground, treatment of water if released to surface streams, and the effect on the hydrologic regime.

(4) The plan shall describe each permanent monitoring well to be located in the backfilled area, the stratum underlying the mined coal, and gradient from the backfilled area.

(5) The requirements of paragraphs (N)(1) to (N)(4) of this rule shall also apply to pneumatic backfilling operations, except where the operations are exempted by the chief from requirements specifying hydrologic monitoring.

(O) Underground development waste. Each plan shall contain descriptions, including appropriate maps and cross section drawings, of the proposed disposal methods and sites for placing underground development waste and excess spoil generated at surface areas affected by underground mining surface operations and facilities according to rule 1501:13-9-07 of the Administrative Code. Each plan shall describe the geotechnical investigation, design, construction, operation, maintenance, and removal, if appropriate, of the structures and be prepared according to paragraph (P) of this rule.

(P) Disposal of excess spoil.

(1) Each application shall contain descriptions, including appropriate maps and cross section drawings, of the proposed disposal site and design of the spoil disposal structures according to rule 1501:13-9-07 of the Administrative Code. These plans shall describe the geotechnical investigation, design, construction, operation, maintenance, and removal, if appropriate, of the site and structures.

(2) Each application shall contain the results of a geotechnical investigation of the proposed disposal site, including the following:

(a) The character of bedrock and any adverse geologic conditions in the disposal area;

(b) A survey identifying all springs, seepage, and ground-water flow observed or anticipated during wet periods in the area of the disposal site;

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

(d) A technical description of the rock materials to be utilized in the construction of those disposal structures containing rock chimney cores or underlain by a rock drainage blanket; and

(e) A stability analysis including, but not limited to, strength parameters, pore pressures 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.

(3) If, under paragraph (D) of rule 1501:13-9-07 of the Administrative Code, rock-toe buttresses or keyway cuts are required, the application shall include the following:

(a) The number, location, and depth of borings or test pits. The number, location, and depth shall be determined with respect to the size of the spoil disposal structure and sub-surface conditions; and

(b) Engineering specifications utilized to design the rock-toe buttresses or keyway cuts which shall be determined in accordance with paragraph (P)(2)(e) of this rule.

(Q) Air pollution control plan. For all underground mining surface operations, the application shall contain an air pollution control plan in order to address fugitive dust resulting from erosion. The plan shall include the following:

(1) An air quality monitoring program, if required by the chief, to provide sufficient data to evaluate the effectiveness of the fugitive dust control practices under paragraph (Q)(2) of this rule to comply with applicable federal and state air quality standards; and

(2) A plan for fugitive dust control practices.

(R) Fish and wildlife plan.

(1) Resource information. Each application shall include fish and wildlife resource information for the permit area and adjacent area.

(a) The scope and level of detail for such information shall be determined by the chief in consultation with state and federal agencies with responsibilities for fish and wildlife and shall be sufficient to design the protection and enhancement plan required under paragraph (R)(2) of this rule.

(b) Site-specific resource information necessary to address the respective species or habitats shall be required when the permit area or adjacent area is likely to include:

(i) Listed or proposed endangered or threatened species of plants or animals or their critical habitats listed by the secretary of the interior under the Endangered Species Act of 1973, as amended ( 16 U.S.C. 1531 et seq.), or those species or habitats protected by similar state statutes;

(ii) Habitats of unusually high value for fish and wildlife such as important streams, wetlands, riparian areas, cliffs supporting raptors, areas offering special shelter or protection, migration routes, or reproduction and wintering areas; or

(iii) Other species or habitats identified through agency consultation as requiring special protection under state or federal law.

(2) Protection and enhancement plan. Each application shall include a description of how, to the extent possible using the best technology currently available, the operator will minimize disturbances and adverse impacts on fish and wildlife and related environmental values, including compliance with the Endangered Species Act, during the surface coal mining and reclamation operations and how enhancement of these resources will be achieved where practicable.

(a) This description shall:

(i) Be consistent with the requirements of rule 1501:13-9-11 of the Administrative Code;

(ii) Apply at a minimum, to species and habitats identified under paragraph (R)(1) of this rule;

(iii) Include protective measures that will be used during the active mining phase of operation. Such measures may include the establishment of buffer zones, the selective location and special design of haul roads and powerlines, and the monitoring of surface water quality and quantity; and

(iv) Include enhancement measures that will be used during the reclamation and postmining phase of operation to develop aquatic and terrestrial habitat. Such measures may include restoration of streams and other wetlands, retention of ponds and impoundments, establishment of vegetation for wildlife food and cover, and the replacement of perches and nest boxes. Where the plan does not include enhancement measures, a statement shall be given explaining why enhancement is not practicable.

(3) Fish and wildlife service review. Upon request, the chief shall provide the resource information required under paragraph (R)(1) of this rule and the protection and enhancement plan required under paragraph (R)(2) of this rule to the U.S. department of the interior, fish and wildlife service regional or field office for their review. This information shall be provided within ten days of receipt of the request from the service.

(S) For dates of federal rules and federal laws referenced in this rule, see rule 1501:13-1-14 of the Administrative Code.
