7. (7) Demonstration of restoration of the ecological function of all reconstructed perennial and intermittent stream segments.
8. (8) Application for each phase of bond release under § 800.42 of this chapter.

(d) Backfilling and grading plan.

1. (1) The reclamation plan must contain a plan for backfilling surface excavations, compacting the backfill, and grading the disturbed area, with contour maps, models, or cross-sections that show the anticipated final surface configuration of the proposed permit area, including drainage patterns, in accordance with §§ 817.102 through 817.107 of this chapter, using the best technology currently available.

2. (2) The backfilling and grading plan must describe in detail how you will conduct backfilling and related reclamation activities, including how you will -

   1. (i) Compact spoil to reduce infiltration to minimize leaching and discharges of parameters of concern.
   2. (ii) Limit compaction of topsoil and soil materials in the root zone to the minimum necessary to achieve stability. The plan also must identify measures that will be used to alleviate soil compaction if necessary.
   3. (iii) Handle acid-forming and toxic-forming materials, if present, to prevent the formation of acid or toxic drainage from acid-forming and toxic-forming materials within the overburden. The plan must be consistent with paragraph (n) of this section and § 817.38 of this chapter.

(e) Soil handling plan - (1) General requirements.

1. (i) The reclamation plan must include a plan and schedule for removal, storage, and redistribution of topsoil, subsoil, and other material to be used as a final growing medium in accordance with § 817.22 of this chapter. It also must include a plan and schedule for removal, storage, and redistribution or other use of organic matter in accordance with § 817.22(f) of this chapter.
2. (ii) Except as provided in paragraphs (e)(1)(iii) and (iv) of this section, the plan submitted under paragraph (e)(1)(i) of this section must require that the B soil horizon, the C soil horizon, and other underlying strata, or portions of those soil horizons and strata, be removed separately, stockpiled if necessary, and redistributed to the extent and in the manner needed to achieve the optimal rooting depths required to restore premining land use capability and to comply with the revegetation requirements of §§ 817.111 and 817.116 of this chapter.
3. (iii) The plan submitted under paragraph (e)(1)(i) of this section need not require salvage of those soil horizons which you demonstrate, to the satisfaction of the regulatory authority, are inferior to other overburden materials as a plant growth medium, provided you comply with the soil substitute requirements of paragraph (e)(2) of this section.
4. (iv) The plan submitted under paragraph (e)(1)(i) of this section may allow blending of the B soil horizon, the C soil horizon, and underlying strata, or portions thereof, to the extent that research or prior experience under similar conditions has demonstrated that blending will not adversely affect soil productivity.
5. (v) The plan submitted under paragraph (e)(1)(i) of this section must explain how you will handle and, if necessary, store soil materials to avoid contamination by acid-forming or toxic-forming materials and to minimize deterioration of desirable soil characteristics.

      2. (B) The use of the overburden materials that you have selected, in combination with or in place of the topsoil or subsoil, will result in a soil medium that is more suitable than the existing topsoil and subsoil to support and sustain vegetation consistent with the postmining land use and the revegetation plan under paragraph (g) of this section and that will provide a rooting depth that is superior to the existing topsoil and subsoil.
      3. (C) The overburden materials that you select for use as a soil substitute or supplement are the best materials available to support and sustain vegetation consistent with the postmining land use and the revegetation plan under paragraph (g) of this section.

   2. (ii) For purposes of paragraph (e)(2)(i) of this section, the regulatory authority will specify the -

      1. (A) Suitability criteria for substitutes and supplements.
      2. (B) Chemical and physical analyses, field trials, or greenhouse tests that you must conduct to make the demonstration required by paragraph (e)(2)(ii) of this section.

At a minimum the plan must -

   1. (i) Identify the anticipated postmining groundwater level for all locations at which you propose to place acid-forming or toxic-forming materials.

   2. (ii) When approved in the permit, place acid-forming and toxic-forming materials in an excess spoil fill or a coal mine waste refuse pile, using one or both of the following techniques, as appropriate:

      1. (A) Completely surround acid-forming and toxic-forming materials with compacted material with a hydraulic conductivity at least two orders of magnitude lower than the hydraulic conductivity of the adjacent spoil or coal mine waste.
