§ 150.140.16  MINERAL EXTRACTION.
   All uses in the RP, Resource Production district are on notice that earth removal, quarrying, gravel processing, and mining, as regulated in this chapter, may be permitted anywhere within this district with a conditional use permit. Specific performance standards for earth removal, quarrying, gravel processing, and mining operations are as follows:
   (A)   Maximum depth of excavation shall not be below existing groundwater table.
   (B)   Where necessary the Commission may require the applicant to construct or improve a road to accommodate the truck travel necessitated by the operations as a condition to such operations, and for the purpose of routing traffic around residential areas and preventing the deterioration of existing roads which are not "all weather" roads. All access roads shall be considered part of the mining operation.
   (C)   Setbacks.
      (1)   All mining operations shall be a minimum of 90 feet from any public right-of-way, not including ingress and egress roads.
      (2)   All mining operations shall be a minimum of 550 feet from any lake, stream or wetland.
      (3)   All mining operations and all ingress and egress roads shall be a minimum of 90 feet from any other property line.
      (4)   All mining operations shall be a minimum of 500 feet from any church or public park.
      (5)   All mining operations shall be a minimum of 1,000 feet from any school, hospital or nursing home.
      (6)   All mining operations and all ingress and egress roads shall be a minimum of 300 feet from an existing house on an adjacent property.
      (7)   All ingress and egress roads shall be by the most direct route to a public right-of-way.
      (8)   All ingress and egress roads will require a legal driveway permit.
   (D)   Any on-site permanent processing plant shall not be located closer than 300 feet from any property line and adjoining public rights-of-way and shall, where practicable, be located at a lower level than the surrounding terrain to lessen visual and noise impacts.
   (E)   (1)   Sight barriers shall be provided along all boundaries of the site where quarrying, gravel processing and mining is proposed which lack natural screening conditions through existing vegetative growth. The following minimum standards shall apply:
      (2)   A continuous screen at least six feet in height is required to provide maximum screening of the site.
         (a)   This landscape buffer may consist of earthen berms, and/or living materials.
         (b)   Berms shall be constructed with slopes not to exceed a 1:3 gradient with side slopes designed and planted to prevent erosion, and with a rounded surface being a minimum of two feet in width at the highest point of the berm, and extending the length of the berm. Berm slopes shall be protected with sod, seed, shrubs or other forms of natural ground cover.
   (F)   Nuisance abatement.
      (1)   All equipment shall be maintained and operated in such a manner so as to eliminate, as far as practicable, excessive noise and vibrations which are not necessary in the operation of such equipment.
      (2)   Air pollution in the form of dust and dirt shall be kept to a minimum by the use of equipment and methods of operation designed to avoid any excessive dust or dirt or other air pollution. Interior roads used in the operation shall have their surfaces treated to minimize any such nuisance.
      (3)   A noise barrier shall be provided along all boundaries of the site where quarrying, gravel processing and mining is proposed, which lack sufficient existing vegetation to meet the minimum standards, as follows:
         (a)   There shall be six rows of mixed evergreen trees of species recommended by the District Forester, staggered six feet apart and no less than three years of age planted parallel to the boundaries of the property.
         (b)   The spacing between rows shall not exceed six feet.
         (c)   The spacing between trees within a row shall not exceed six feet.
         (d)   The Planning Commission may allow the preservation of existing trees within the setback areas to qualify toward satisfying division (a) above.
         (e)   A "Performance Guarantee" concerning the trees will be required.
         (f)   The screening shall be maintained in a healthy condition, free from refuse and debris. All unhealthy or dead material shall be replaced within one year of damage or death, or at the next appropriate planting period, whichever comes first.
   (G)   Reclamation of mined or excavated areas.
      (1)   Earth removal, quarrying, gravel processing and mining, shall be considered temporary uses. Mined or excavated sites shall be reclaimed properly and in a timely fashion.
      (2)   A "Performance Guarantee" shall be posted by the land owner with the Breitung Township Board to cover the estimated costs of reclamation. This "Performance Guarantee" shall be received by the Township Clerk within 30 days of the approved site plan. "Performance Guarantee" as used herein shall mean a cash deposit, certified check, or irrevocable bank letter of credit, acceptable to the township, in the amount of the estimated cost of reclamation. It shall be subject to review and adjustment by the Commission at the end of 12 months, and thereafter at two year intervals.
      (3)   Reclamation shall be completed as agreed upon by the Commission and applicant in an approved development site plan.
      (4)   Inactivity at a site for a continuous 12 month period shall constitute termination of mining activity and require that site reclamation commence and be completed.
      (5)   Upon the failure of any operator to perform reclamation of the mining site in a proper and timely manner as agreed to in the approved site plan the "Performance Guarantee" will be forfeited. The Breitung Township Board shall use the funds to cover the cost of restoring the site and administrative cost incurred in so doing. Any cost in addition of those covered by the "Performance Guarantee" shall be billed to the operator and a lien placed against the subject property. If unpaid, the cost shall be collected in the same manner as delinquent taxes or as allowed by law.
      (6)   Standards controlling reclamation.
         (a)   Excavated areas shall not collect stagnant water.
         (b)   Surface of such area which is not intended to be permanently submerged shall be graded or back-filled with non-toxic, non-flammable and non-combustible solids as necessary to produce a surface that will minimize wind and water erosion, and which will be generally compatible with the adjoining land area.
         (c)   The banks of all excavation shall be sloped to the waterline in a water producing excavation and to the pit floor in a dry operation at a slope which shall not be steeper than one foot vertical to three feet horizontal.
         (d)   Vegetation shall be restored within one year by the appropriate planting of indigenous grasses, trees, or shrubs to establish a permanent vegetative cover on the land surface and to minimize erosion.
         (e)   Maintenance.
            1.   Slopes and surfaces shall be maintained as agreed in the development site plan.
            2.   Erosion areas shall be filled and the surface restored.
            3.   All unhealthy or dead material shall be replaced within one year of damage or death, or at the next appropriate planting period, whichever comes first.
         (f)   Reclamation plans shall follow the standards detailed for the most appropriate uses(s) allowed by this chapter.
         (g)   Future uses shall conform with uses indicated in the township Master Plan or as approved in the development site plan.
