Re: Response to DWR Comment Letter of 08/19/24
WQ0045463 Wastewater Irrigation System -Chatham County, NC
Firefly Overlook Lot 6, Apex, NC
Mr. Anthony:
The purpose of this correspondence is to offer reply to your comments/additional
information requested in your letter of August 19, 2024. Responses below will be given
in the order of the items listed in your letter. The comments included in your letter which
pertain to aspects of the Soil Evaluation are as follows:
G. Soil Evaluation:
1. A 40.5% drainage coefficient is being proposed. Per the DWR Soil Scientist Evaluation Policy
and the EPA Process Design Manual: Land Treatment of Municipal Wastewater Effluent (EPA
625/R-06/016), a DC of 4-10% is recommended. How has the recommended drainage coefficient
been determined? Additionally, there is a large variance in drainage coefficient between this site
and surrounding lots despite very close proximity and similar soil types. Please explain the
reasoning for this variance
As we have discussed with the Division previously, the measurement of Ksat can be
highly variable even within small areas. In the case of this lot, lower conductivity
values necessitated a higher drainage coefficient to provide a loading rate within the
SFR loading group range for this lot. It is our understanding from the Division's
own guidance document that this is permissible, provided justification is given:
"...Values for this drainage coefficient shall not exceed 1.0 (100%). Considerations
for the drainage coefficient shall include reliability and consistency of Ksat data,
depth to seasonal high water table (apparent or perched), depth to the restrictive
horizon, slope, landscape position, inclusions of minor amounts of more limiting
soils, etc. The soil scientist sealing the report shall provide a discussion of
considerations in determining the drainage coefficient selected for the individual
system."
216 S. Swing Rd., Suite 1 Y.Greensboro, NC 27409 Y. 336-662-5487

In response to this, the following justification was given in our originally submitted
soil report:
"In the case of this submittal, the Ksat data were found to be relatively consistent
with one another. We recognize that the subsoil is restrictive as evidenced by the
perched soil wetness indicators, but the proposed drain field is located mostly on a
broad linear side slope with 18-20% slopes, thereby preventing ponding of any
applied wastewater. The soil characteristics are also consistent with one another as
evidenced by the soil boring logs and soil profile descriptions, suggesting that
unexpected soil inclusions should not be of concern."
If you have any further questions, please feel free to contact me directly
([e-mail] or 336-662-5487).
Sincerely,
kp SOII s��F�
