All excavation operations conducted or carried on in established excavation districts are subject to the following limitations, restrictions and controls.
(A) Dust, noise, vibration, smoke, lights and odors. All equipment and machinery used on the site of an excavation operation shall be constructed, maintained and operated in such a manner as to reduce dust, noise, vibration, smoke, welding lights and odors to a minimum. Access and haulage roads on the site shall be maintained in a dust-free condition by surfacing or other treatment.
(B) Fencing or barriers. Fencing or other suitable barriers shall be created and maintained on the excavation site or on portions of the site where such fencing is practicable and necessary because of dangerous conditions created by the excavation.
(C) Related manufacturing operations. The manufacture of concrete building blocks or other similar blocks, the production or manufacture of lime products, the production of ready-mixed concrete, the production of asphalt mixes and any similar production or manufacturing processes which might be related to the excavation operation shall not be permitted, except as otherwise provided in Chapter 155 of this code.
(D) Washing. The washing of sand and gravel shall be done so as to prevent the discharge of wastewater directly into adjacent natural watercourses or onto any public or private roads or any private property without the consent of the owner.
(E) Hours of operation. Excavation operations shall not begin before 7:00 a.m. and shall not continue after the hour of 6:00 p.m., and no operation shall take place on Sundays or legal holidays. During periods of national or unusual emergency, time and hours of operation may be altered at the discretion of the County Commission.
(F) Excavation and backfilling.
(1) Where backfilling is required, the excavation shall be graded or backfilled with non-noxious, nonflammable, noncombustible solids. The materials used or the method of fill shall be such as to not create a health hazard, nor be objectionable because of odor or unsightliness.
(2) The graded or backfilled area shall not collect or permit stagnant water to remain thereon.
(3) The peaks and depressions of the excavation area shall be reduced to a surface which will result in level or gently sloping topography in substantial conformity with land areas immediately surrounding and which will minimize erosion due to rainfall.
(4) In any rehabilitation procedure which takes place in sand and gravel pits, or on other sites where the material is of loose or friable nature, no slope shall be left which is steeper than a ratio of one and one-half horizontal to one vertical. In no case shall any slope exceed the normal angle of repose of the material involved.
(G) Cessation of operation; condition of premises. Within one year after the cessation of the operation, all temporary structures (except fences), equipment, rock piles, rubble heaps or other debris shall be removed or backfilled into the excavation so as to leave the premises in a neat and orderly condition.
