V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
The application information depicts the location of the proposed home and wastewater system components. During
an on -site inspection, performed on March 9, 2021, it was stated that the home would be served by an existing water
supply well, which is greater than 100 feet from the proposed irrigation site and wastewater system. Written
confirmation of this is requested, or a statement placed in the permit that any future wells would need to adhere to this
set back distance.
Additional scrutiny of soil characterization may be appropriate — refer to WiROs 3/9/2021 Compliance Inspection
Report.
15A NCAC 2T .0605(p) requires a vertical separation of 18 inches between the apparent seasonal high water table
and the ground surface. An argument could be made that the apparent seasonal high water table is present at the
surface. Although it is proposed that an additional 18 inches of appropriate fill will be provided, no information was
provided to indicate if the drip irrigation line would be installed at the surface (i.e. to enable 18 inches of separation)
or whether the drip line would be installed below the surface of the material.
