facility is currently peiruitted to be compliant with 15A NCAC 02T .0506(c). Is the facility no
longer meeting the reclaimed water quality effluent standards outlined in Attachment A and the
peiruit? Please note, if the facility is no longer compliant with 15A NCAC 02T .0506(c), then
setbacks from drip irrigation sites to property lines will be increased from 0 feet to 50 feet. Please

G. Specifications:
1. Signed and sealed engineering specifications were not provided in the response package. Was the
"Engineer's Evaluation of Valve Installation" letter meant to serve as a specification cover letter
for the product specification sheets? If so, this document was not sealed. Please provide
specifications meeting the requirements of 15A NCAC 02T .0504(c)(2).
H. Engineer's Evaluation Letter:
1. On the second page of the letter, there appears to be a revision in the equalization tank's storage
volume from 54,496 gallons to 49,274 gallons. Please confirru that the new equalization tank's
effective storage volume is 49,274, and please revise Section V.11.a. of the WWIS 06-16
application foiru to reflect the current storage volume so that the Non-Discharge Branch can revise
the facility description, accordingly.
2. Within the description and rationale for the 90%outlet piping,it mentions that the floor drain within
the drum screen building pumps back to the influent pump station. The influent pump station was
not included within the schematic and hydraulic profile on Sheet N-2.1 and the piping does not
appear to be depicted on the facility layout on Sheet N-3.2. Staff in the Winston-Salem Regional
Office indicated that the influent pump station was at a much higher elevation than the rest of the
treatment facility; please provide additional infoiruation regarding the described piping
configuration between the drum screen and the influent pump station.
I. Engineering Calculations:
1. The Engineer's Evaluation included calculations comparing the initially designed equalization
pumps to the gravity knife valve configuration. The letter summarizing the results was not sealed

Manual to reflect the modified facilities.
