Dear Mr. Rick Trone,
NC Dept of Environmental Quality
AUG - 9 2019
Raleigh Regional Office
This response is in reference to the site visit on June 21, 2019 and the subsequent notice of
violation issued July 5, 2019, and received in the Holly Springs office July 11, 2019.
1. Please explain how the cross -connection at 216 Scarlet Tanager Circle occurred.
a. On Friday, June 21, the Town had the reclaimed line off for repair being made by
the developer on the main line on New Hill Road. The only person that called and
notified us that their water was off was, 216 Scarlet Tanager Drive. Once the site
was investigated, staff found that the connection at 2I6 Scarlet Tanager Circle
was not in compliance with state and local specifications.
2. Please provide this office with confirmation that no other similar cross -connections have
occurred associated with this permit, and how this determination was achieved.
a. Immediately following the finding of the reclaimed water line, it remained out of
service at the entrance to the neighborhood. The reclaimed water line remained
cut off for 5 days. During this time Holly Spring's staff visited the existing
residences and verified potable water was running in the residence. The Town
placed a hold on the 25 lots under construction and is requiring the builder to dig
behind each reclaimed setter on the public side, to verify purple reclaimed tape is
on the reclaimed service and the correct meter is in place, as required by the state
and local standards.
3. Indicate in your response any measures that the Town is undertaking to prevent other
cross -connections between reclaimed and potable water from occurring associated with
this and related reclaimed water distribution permits held by the Town of Holly Springs.
a. The Town has purchased a conductivity meter that will assist with the inspections
prior to the certificate of occupancy is issued. This meter will be used as a guide,
since a true water quality sample will not be tested.
b. The Town is also looking into changing the reclaimed meter setter specification to
have reverse threading from the threading on the potable meters.

Currently, Fielding Homes (the builder) corrected the connection. Fielding has conducted an
independent flushing of the potable lines and has successfully tested the lines within the house.
Fielding will be submitting all of this documentation prior to the home being occupied.
Thank you for your assistance and please let me know if you have any further questions.
