(A) All private sewage disposal systems within the limits of Macon County shall be installed, modified, or serviced by an Illinois licensed private sewage disposal system installation contractor; and all such systems shall be pumped, cleaned, and the contents hauled and disposed of by an Illinois licensed private sewage disposal system pumping contractor; provided, however, that a homeowner may install and/or service a private sewage disposal system which serves his or her own personal single-family residence.
(B) All private sewage disposal systems shall have a soil investigation. Soil investigations shall be the sole method for determining the absorption capacity of the soil. Percolation test results will no longer be accepted. Soil investigations shall be conducted in the following manner.
(1) Determination of soil characteristics on site proposed for development with private sewage disposal systems shall be based on soil boring data collected by a soil classifier or an Illinois licensed professional engineer.
(2) There shall be a minimum of three borings per soil absorption system site. The soil borings shall be at least 50 feet, and the proposed subsurface seepage system shall be located within the area where the soil borings were located. More soil borings may be necessary for accurate and appropriate evaluation of a site where there is some concern about the consistency of the soil materials. One of the borings shall be made at the lowest elevation of the proposed absorption field area. Borings shall extend a minimum of 60 inches below the natural ground surface. An observation pit shall be used in gravelly materials.
(3) Observation and determination of soil characteristics also may be determined from a pit dug by a backhoe or other excavating equipment. The County Health Department may require soil pits (backhoe excavation) in cases where there has been previous or current fill material, cutting of soils, or where gravelly soils were encountered. Such soil pits shall be prepared at the perimeter of the expected soil absorption area to minimize damage to natural soil structure. Soil pits shall extend a minimum of 60 inches below the natural ground surface.
(4) Site characteristics to be described include zones of seasonal and permanent water saturation, U.S.D.A. soil textural changes, U.S.D.A. soil structural features, slope, compaction and depth, soil coloration, depth of limiting layer, depth of soil mottling (depth to low chroma equal to or less than 2 and a value of 4 or more- Munsell Color System), internal drainage classification, permeability range, and other limiting soil characteristics that may reduce permeability.
(5) Soil investigations shall be performed within three years prior to permit application. In the event that the area undergoing soil analysis is altered after the soil investigation is performed, the County Health Department may require an additional soil investigation to ensure that the results have not been affected.
(C) All septage disposal sites within the county shall be inspected by the Health Department to determine compliance with the provisions of this subchapter. If the disposal sites are determined to be unacceptable, the Health Department shall issue written notice to the users and owners of that site informing them that the site shall not be used for disposal of septage.
(D) A private sewage disposal system pumping contractor or homeowner servicing his or her personal residence system shall supply a list of all septage disposal sites utilized by either the contractor or homeowner to the County Health Department.
(E) The private sewage disposal system installation contractor, the private sewage system pumping contractor, and the homeowner who constructs, installs, repairs, modifies, or maintains private sewage disposal systems, or cleans or pumps waste from private sewage disposal systems shall perform work in accordance with the standards promulgated under authority granted in the Illinois Private Sewage Disposal Licensing Act and Code, as from time to time amended.
