Notes:
1. These distances have been determined for use in clay, silt, and loam soils only. The minimum distances required for the use of a private sewage disposal in sand or other types of soil shall be determined and approved by the Village when the soil in question can provide equal or greater treatment of the sewage. See subsection 4-2-7(D) of this chapter for additional requirements.
2. The building sewer may be located to within 10 feet of a well or suction line from the pump to the well when cast iron pipe with mechanical joints or schedule 40 PVC pipe with watertight joints is used for the building sewer.
3. See subsection 4-2-7(D)4 of this chapter for details on the separation of sewer and water lines.
4. The minimum distance allowable from an in ground swimming pool is 25 feet. See subsection 4-2-7(L) of this chapter for additional requirements.
5. Whichever line is most restrictive.
6. Class V injection wells are defined in Illinois Pollution Control Board rules. They are typically a shallow well used to place fluids directly below the land surface. See e.g., 35 Illinois Administrative Code 704.105, 704.106, and 704.280.
7. A lesser separation distance may be obtained with approval or a waiver from the IEPA.

Notes:
1. Disturbed soils are highly variable and require special on site investigations.
2. Moderate or strong platy structures for the soil textures in groups 4, 5, and 6 have a loading rate of 0.40 g/sq. ft./d. Platy structure having firm or very firm consistency or caused by mechanical compaction has a loading rate of 0.0 g/sq. ft./d.
3. Basal glacial tills structured by geogenic processes have the same loading rates as structureless glacial till.
4. This soil group is estimated to have very rapid permeability and exceeds the maximum established rate in appendix G, exhibit A of this section.
5. n/a means not applicable.
6. These soil groups are estimated to have moderately slow to very slow permeability and are less than the minimum established rate in appendix G, exhibit A of this section.
7. N/R means not recommended. These soils have loading rates considered too low for conventional subsurface disposal.
8. In some areas, lacustrine material may have physical properties similar to glacial till and should be placed in the glacial till columns.
9. Nonswelling (1:1 lattice) clays formed in bedrock residuum have a loading rate of 0.27 g/sq. ft./d. Swelling (2:1 lattice) clays are not recommended for subsurface disposal.
