(A)   General. Soil characteristics shall be described based upon United States Department of Agriculture Natural Resources Conservation Service (NRCS) National Standards. Soil profile descriptions shall include depth in inches from the ground surface to changes in soil texture, soil structure, soil consistence and/or compaction, observed saturation, soil coloration, and redoximorphic features indicative of saturation including, but not limited to, common (2% - 20%) or greater low chroma redox depletions (equal to or less than two and a value of four or more based upon Munsell color chart). Descriptions shall be recorded to a depth of 60 inches.
   (B)   Additional determination and assignments. In addition to the meeting the requirements of subsection (A) above, in describing soil characteristics, a Lake County Licensed Soil Classifier/Soil Scientist shall make determinations and assignments based upon soil profile descriptions as follows:
      (1)   Soil resource group. Each soil profile description shall be classified in accordance with the requirements of Appendix B to establish a soil resource group, soil series or classification, the depth to a limiting layer and observed water, if present.
      (2)   Wastewater loading rates. Each soil profile description shall assign maximum wastewater loading rates in accordance with the requirements of Appendix B, as follows:
         (a)   Soil profile descriptions shall be segregated by horizon.
         (b)   Each segregated horizon shall be assigned a loading rate between zero gallons per day per square foot (gpd/ft2) and 0.8 gpd/ft2.
