A. Cover/Response Letter:
1. The response letter dated August 22, 2022 indicates that the installation of the 90% pipe will reduce
the tank volume to 49,274 gallons (Item H.1). However, Section V. Item I I.a of Form WWIS 06-
16 and the provided engineering calculations lists the flow equalization tank volume as 40,786
gallons. Please address this discrepancy and revise the application, if necessary, to reflect the
equalization tank's volume upon installation of the 90% pipe.
B. Application Fee:
1. Not applicable.
C. Application (Form: WWIS-R 02-21):
Mr. Sean Dwyer is listed as the Signature Authority in Section I, Item 3. Our office recently
received a request on January 18, 2023, that Mr. Dwyer be removed from communications and
replaced with (Mr./Ms.) Wen De Tam. Please confirm that (Mr./Ms.) Wen De Tam is to replace
Sean Dwyer as the Owner/Director of Wallace Loft LLC and Signature Authority for this permit,
and please verify that Mr. Dwyer is no longer affiliated with Wallace Loft LLC so that we may
update our database.
Section V. Item 1 lists Mr. Eric Youngs as the Operator in Responsible Charge (ORC). A review
of our database shows that Mr. Youngs classification status is currently "invalid". Please have Mr.
Youngs contact the Operator Certification group (URL: https:Hdeg.nc.gov/about/divisions/water-
resources/operator-certification/wastewater-operator/staff-ww) to determine the necessary steps
required to return to "active" status. Pursuant to 15A NCAC 08G .0200, the Permittee shall
designate and employ a certified ORC and one or more back-up ORCs. The ORC and back-up
ORC must be in good standing with the Water Pollution Control System Operators Certification
Commission (WPCSOCC).
The response regarding Attachment J — Civil Penalties and Outstanding Violations was answered
as 'No". A Notice of Deficiency was issued January 9, 2023, that outlined deficiencies observed
during the December 2022 inspection. On January 18, 2023, a Notice of Violation was issued
related to compliance monitoring. Please provide an update regarding Wallace Loft LLC's
response to these Notices.
D. Application (Form: WWIS 06-16):
Section IV. Item 7 lists 859 bedrooms contributing to a daily design flow of 105,000 GPD. The
existing permit's facility description lists "894 bedrooms, five administrative/clubhouse
employees, a fitness center, and a pool" contributing to the Cottages of Boone WWTP for a total
daily design flow of 108,530 GPD. Please confirm that the current facility description is accurate,
and if the current facility description is in error, then please update the daily design flow
contributions in Section IV. Item 7 in accordance with 15A NCAC 02T .0114.
2. Section IV. Items 8 and 9 were unanswered. Please revise the application to include responses to
these questions.
Section V. Item 1 I.a. See Comment A. 1.

4. Section V. Item 1 I.c states that two Ultradynamic UV banks were installed with 4 bulbs per bank
and a maximum disinfection capacity of 150 GPM. The existing permit lists dual 130 GPM Severn
Trent UV disinfection systems. Were the Severn Trent units replaced?
5. The response to Section VIIL Item 4, is still answered "no" regarding intent to comply with 15A
NCAC 02T .0506(c) for reduced irrigation setbacks. Based on the provided response letter this
should have been changed to "yes". Please revise the application.
