Indian Creek Overlook Wastewater Collection System
Permit No. WQCSD0644
Dear Mr. Smith:
Thank you for the opportunity to respond to Notice of Violation NOV-2018-2T-001
issued on November 8, 2013 and received by Envirolink on November 13, 2018. This letter shall
serve as a formal response to the same on behalf of Envirolink and the owner, Indian Creek
MHP, LLC. At the outset, I would like to note that no SSO occurred at the Indian Creek Overlook
facility. Substantial investigation by Envirolink staff confirmed there was no SSO.
Envirolink offers the following response to the questions posed in the November 8 NOV:
1. Who owns this collection system?
Response: Indian Creek MHP, LLC owns the collection system.
2• Who is responsible for operating and maintaining the collection system?
Response: Envirolink, Inc. contracted with the owner to operate and maintain the collection
system and Envirolink employee, Chris Peele, is the Operator in Responsible Charge.
3. Please explain the collection system situation/status in detail:
a• What happened to cause this failure in the collection system. (i.e.
clogged/broken line, broken pumps, etc.)
Response: On September 12, 2018, Indian Creek Overlook ORC, Chris Peele, noticed a problem
with the lift station in question during his weekly inspection. Once the lift station pumps were
cleared and checked, it was determined that the sanitary sewer force main connecting the lift
station to the City of Raleigh collection system was not operating as designed. Mr. Peele began
to pump and haul immediately to prevent an SSO. It was determined that the force main that
connects the lift station to the City of Raleigh collection system was not operating correctly. The
City of Raleigh and Envirolink staff were both onsite and worked collectively to pump and haul

preventing an overflow situation. Once it was established that the issue was the responsibility of
Indian Creek, Envirolink staff took the lead.
The Indian Creek Overlook system is privately owned and discharges to the City of Raleigh
gravity collection system. On the evening of September 12, 2018, after pumping and hauling the
lift station down to a safe level, it was agreed with the City of Raleigh staff that an Envirolink
technician, Jeff Cincinnati, would remain onsite until the bypass pump was installed. Mr.
Cincinnati was there to monitor the lift station level and be in position to put resources to work,
if needed, to prevent an SSO. Envirolink staff provided 24-hour per day onsite monitoring until
the bypass pump was installed. The bypass diesel pump included an automatic control system,
operating floats and a control panel. Due to the automatic pumping capability and continued
telemetry monitoring, the 24-hour per day monitoring was reduced to daily inspections. The
bypass pump and controls were supplied and installed by Charles R. Underwood, Inc., an
established water and wastewater utility contractor. The bypass pipe length was approximately
700 feet in length through the woods and hilly terrain. The bypass was inspected daily while in
operation from September 13 to October 10, 2018. Final repairs were completed on or around
October 10, 2018 the lift station was put back in service. The force main from the lift station to
the gravity discharge had to be taken apart in sections for inspection by ccty and jetting to clear
the blockage. The force main was reassembled and put back into service on October 10, 2018.
b. What length of the collection system was bypassed?
Response: Approximately 700 feet.
C. When was the issue first discovered? Please clearly detail the duration of
the collection system failures.
Response: The issue was first discovered on September 12, 2018 and was corrected on October
10, 2018. Please see the above response to question 3a for further detail
d. How was the issue discovered?
Response: The issued was discovered during a regularly scheduled weekly inspection by ORC
Chris Peele. Mr. Peele determined during the inspection that lift station level was too high.
Further inspection revealed the lift station was not operating properly. The pumps were pulled
cleared and reinstalled. After checking and reinstalling the pumps the lift Station level continued
to rise. Both the City of Raleigh and Envirolink staff were onsite until it was determined which
system was not working properly and who was responsible. Please see the above response to
question 3a for further detail
e. Specifically, detail the activities/repair efforts that were conducted to
temporarily remedy the inoperable collection system?
Response: Please refer to the above response to question 3a.
f. How was the collection system ultimately repaired?

Response: Two pump stations are present at Indian Creek Overlook.
S. Are floats and alarms present at all of the pump station(s)? Are the connected to a
telemetry system? Are all lift stations equipped with operational duel pumps?
Response: Floats and alarms are present at both pump stations. Both pump stations are
connected to telemetry. All lift stations are equipped with operational duel pumps.
6. How often is (are) the pump station(s) inspected? Are records kept of these
inspections?
Response: The pump stations are inspected weekly and records are kept of the inspections.
7. Was any wastewater discharged to the surface?
Response: No wastewater was discharged to the surface.
8. Based on DWR observations, conversations with the City of Raleigh staff and a
neighborhood resident, it appeared that the issue(s) and the bypass pumping lasted
several weeks. The bypass pumping required roads to be inaccessible due to
piping/hose in the roadway during this time. Please explain how long the bypass
Pumping took place and why it took so long to repair the system.
Response: The bypass pumping occurred from September 13, 2018 until October 10, 2018. The
hilly terrain and distance of the force main made jetting and cleaning the force main difficult.
period which caused delays in completing the work. The work was completed
Further, Hurricane Florence and Hurricane Michael produced substantial rain during this tas quickly as
ime
possible given conditions present, including terrain, distance to the force main and torrential
rains.
9. It was observed by City of Raleigh staff and DWR staff during site visits that no one
was present operating and maintaining the portable pump and pump around. Please
explain why no one was onsite operating the portable pump and observing the bypass
pumping.
Response: The bypass pump was inspected daily during the period it was operated from
September 13, 2018 until October 10, 2018. The system included floats and a control panel for
