§ 9.17. Mining, mineral exploration, and borrow pits.
9.17.1
Definitions: As used in this Ordinance, unless the context otherwise requires:
AREA OF DISTURBANCE: That area of land that has undergone physical alteration to the natural topography and/or vegetation as a consequence of mining exploration.
EXPLORED LANDS: The surface, subsurface and water of an area in which mineral exploration is being or has been conducted, including private ways and roads appurtenant to any such area, land excavations, workings, waste, and areas on which structures, facilities, equipment, machines, or other materials used in exploring operations are located.
MINERAL EXPLORATION: Ordinary grading, construction of roads or platforms, core sampling and drilling, of lands for determining the feasibility of the extracting of solid minerals.
OVERBURDEN: All the earth and other material which lies above natural deposits of ores or minerals, and includes all earth and other materials disturbed from their natural state in the process of surface mining.
RECLAMATION OF EXPLORED LANDS: The combined process of land treatment that mitigates water degradation, air pollution, damage to aquatic or wildlife habitat, flooding, erosion and other adverse effects from exploration including all associated lands, so that explored lands are reclaimed to a usable condition which is readily adaptable for alternate land uses and minimize danger to the public health, safety, and welfare. This process may extend to back filling, to original grades and previous natural conditions.
REMOVAL: The actual process of digging or otherwise removing the substance being moved.
9.17.2

The operation may continue under the new owner during the sixty (60) day grace period. Failure of the new owner(s) to place on file with the County the necessary information and documents within said sixty (60) day period shall constitute a violation of this Ordinance.
9.17.3.6.2
Updating the information in the existing Comprehensive Site Development Plan for the operation to reflect a change of legal ownership of the mining/quarrying operation shall not constitute an amendment to the plan, unless significant changes are proposed to the nature or intensity of the operation itself or to plans, proposals, objectives, or time-frame for land stabilization or reclamation.
9.17.3.7
Cessation of Operation.
9.17.3.7.1
Upon cessation of operation, defined as no physical operations on-site within a consecutive period of one (1) year, the operator shall begin with the reclamation or land stabilization, as specified in § 9.17.4, herein, unless an application for inactive status has been submitted and approved.
9.17.3.7.2
The operator shall have up to twenty-four (24) months after the date of cessation of operations to submit a written application to the Building Official, requesting that the mining/quarry site be placed on inactive status. Said inactive status shall be granted for up to three (3) years with no effect on its zoning status. If, at the end of three years, active mining/quarrying has not been resumed, it shall be deemed that mining/quarry operations have permanently ceased. At such time, the operator shall complete reclamation or land stabilization, as specified in § 9.17.4, herein. When a mining/quarry site is placed on inactive status, all exposed critical disturbed areas shall be stabilized and all measures employed for erosion and sedimentation control shall be maintained by the operator until such time as active mining/quarrying is resumed or said reclamation/land stabilization has been completed or said reclamation/land stabilization has been completed.
9.17.3.8
Amendments to Plan. Unless otherwise specified herein, once approved, there shall be no significant changes or variation involving the nature or intensity of the operation itself or to the plans, proposals, objectives or time-frame for land reclamation/land stabilization in the Comprehensive Site Development Plan, unless approved, after a public hearing as set out in Article XIII, Amendments, of this ordinance, by the Board of Commissioners and all applicable state regulating authorities. The Operator shall submit any proposed changes in the approved Plan to the Board of Commissioners or their designated official(s) and to the appropriate state agencies for approval as an amendment to this Plan prior to changing or varying from this Plan. Request for amendment shall be complete in all details necessary to show the new plan of action and all lands to be affected. This requirement shall not apply to existing operations for which no Comprehensive Site Development Plan or Surface Mining Land Use Plan exists, provided that such existing operations shall comply § 9.17.3.10, Existing Mineral-Material Extraction and Surface Mining Operations, and § 9.17.3.10, Registration Required, herein.

9.17.5.2
Reclamation plans, if approved, shall be considered conditions of development approval, unless otherwise specified by the Building Official. The Board of Commissioners may require an applicant to post a bond calculated on a specific amount per acre for the purpose of insuring proper reclamation of the land.
9.17.5.3
Amendments: There shall be no amendment to the Plan unless such amendments are first approved by the Board of Commissioners or their designated official(s).
9.17.5.4
Requirements: The following requirements shall be met in the Rehabilitation/Land Stabilization Plan:
1.
When any extraction has been completed, such area shall either be left as a permanent spring-fed lake or the floor thereof shall be leveled in such manner as to prevent the collection and stagnation of water and to provide proper drainage without excessive soil erosion, and shall otherwise comply with these requirements.
2.
All affected land (excluding dimension stone quarry excavation pits) shall be graded into a rolling topography and blended in with the existing landscape. Boulders, and overburden may be incorporated into protective barriers or berms, as necessary, provided such materials shall not be deposited in the required buffer areas except as specifically provided in § 9.17 and subsequent sections, herein.
a.
If grades are to be left below the water table, the excavation shall extend to a depth of two (2) feet below a water producing level.
b.
Excavated area shall be graded to blend with the surrounding topography.
c.
If backfilling the excavation, the backfill shall be non-noxious and non-inflammable solids to assure that the excavated area will not collect and retain stagnant water. The graded and/or back-filled surface shall create a gentle rolling topography to minimize erosion by wind or rain and substantially conform to the contour of the surrounding area.
d.
The banks of all extraction, when not back-filled, shall be sloped at a grade of not less than two (2) feet horizontal to one (1) foot vertical.
e.
Spoil banks shall be graded to a level suiting the existing terrain.
f.
All banks and extracted areas shall be surfaced with at least six (6) inches of suitable soil, except exposed rock surfaces, and shall be planted or seeded with trees, shrubs, legumes or grasses and maintained until the soil is stabilized.
3.
All equipment and structures shall be removed within three (3) months of the completion of the extraction of materials.
4.
All accessory structures, mechanical equipment, and stockpiled materials associated with the operation shall be removed within three (3) months of completion of the extraction of materials.
5.
Vegetative Stabilization - The Owner or lessee shall provide a high quality, enduring vegetative ground cover of properly planted and nurtured perennial vegetative species suited for the specific planting zone involved. The perennial vegetative species shall provide a complete, thorough stabilization by providing root mass and cover for the total disturbed area. If forest land is the reclamation objective, a vegetative ground cover will also be provided prior to or concurrent with tree seeding or the planting of tree seedlings.
6.
Structural Stabilization - Permanent structural control measures, i.e. stone riprap, ditches, berms, paved chutes, or piped down drains, etc., shall be utilized to convey concentrated storm flows down slopes to stable outlets. These measures shall be necessary in areas where concentrated storm flow velocities may cause erosion.
7.
Lakes or Ponds - All proposed lakes or ponds shall comply with all applicable local, state and federal regulations and requirements.
8.
All exposed critical disturbed areas shall be stabilized and all measures employed for erosion and sedimentation control shall be maintained by the operator until reclamation or land stabilization can be completed.
9.
Any security fencing or barriers shall be removed upon the closure of the borrow pit and completion of reclamation except those needed to secure dimension stone quarry excavation pits.
