Subject: Response to Notice of Violation & Intent to Issue Civil Penalty
Tracking No.: NOV-2021-DV-0041
Sanitary Sewer Overflows — October 2020
Collection System Permit No. WQCS00312
Archdale Collection System
Randolph County
I acknowledge receipt of your Notice of Violation & Intent to Issue Civil Penalty regarding
an SSO event on October 30, 2021. The NOV, dated 1/25/2021, was received 1/29/2021.
The following narrative and attachments have been included to explain the cause of this
event and the actions being taken to prevent future overflows.
Narrative - Incident Number 202002902: Friday, October 30, 2021
Weant Road is Archdale's largest sewer pump station. Currently it is run by a pair of
100HP pumps (#1 & #2) and a 250HP pump (#3). In the weeks before this SSO, pump #3
was sent off for repairs/PM and then placed back into service. While #3 was away, a large
bypass pump was brought onsite as back-up, and to assist with the $1.3M force main
project nearing completion.
On 10/20/20, staff called Carolina Lift Stations (CLS) regarding a potential seal failure on
pump #2. The pump was not performing well and has experienced repetitive cavitation
and seal issues. Staff sought advice from CLS to resolve this ongoing issue. While on
site a few days later, conversations were had about the City's plan to add an additional
250HP pump in the next fiscal year (#4). While looking in the pit where this new pump will
go, CLS staff noted a potential issue with pump #3. It was decided to pull the pump and
get a closer look. Ultimately, CLS cited major concerns with the recently completed work
on pump #3. It was decided that the pump needed immediate attention to avoid a
catastrophic failure and should be sent back for repairs. Ironically, we felt fortunate to
have discovered this problem before major damage occurred and that the work would be

done under warranty. This left 3 pumps in place: #1, #2 (at less than full strength), and
the large bypass pump.
High winds and heavy rain moved through Archdale in the early hours of Friday, October
30, 2020. This storm system included the remnants of Hurricane Zeta, which resulted in
widespread flooding and wind damage. The flow coming into the Weant Road pump
station increased with I/1 during this timeframe and an SSO event occurred as the pumps
in place were overwhelmed.
Throughout this issue, a $7,800/month bypass pump was on site. Our experience with
this large bypass has been very positive in prior extreme rain events, and we were
surprised that the pumps in place became overwhelmed. In any case, staff re -visited the
pump station once flooding receded, cleaned the immediate area, and applied hydrated
lime as required by the City of Archdale's Sewer Overflow Response Plan.
In good news, we learned today that the City will be awarded funding from the state for an
AIA of the sewer system. As part of this study, we will aim to learn more about the I/I
issues that are affecting our pump stations, in addition to assessing the status of the
overall collection system. Also, as noted above, the City will be adopting an updated
Capital Improvement Plan in the coming weeks which has increased the urgency of
implementing an additional 250HP pump at the Weant Road pump station. This new
pump will serve as an insurance policy so the City can minimize the need to rent bypass
pumps when other pumps are out of service.
Also, it is worth mentioning that pump #2's issues have continued. CLS has
recommended that the City replace the suction valves feeding both 100HP pumps as a
starting point for remedying the issue. This work will cost $39,000 and is scheduled to
take place in the coming weeks. Hopefully, these and the numerous other investments
being made to our wastewater system show the City's intent to meet the ongoing
requirements of our collection system permit.
Should you have questions or need further information about this matter, please let me
know. I can be reached by telephone at [phone] or by email at
zholden a(�archdale-nc.gov.
Sincerely,
/a,
eb Holden

Morning,
To make a very long story short, there will likely be an invoice coming from Carolina Lift Stations for coming onsite
at Weant Road PS to diagnose an emergency issue we were having with the pumps.
They were there to help us diagnose one issue, and (un)fortunately discovered another issue.
We
ile Chave s wan issue
s here to
with one of the 100 HP pumps that will likely be fully under warranty with Randall Supply.
help with that, we also had another issue we wanted some advice on, and they discovered that the 250HP pump
has an issue. We have moved forward with sending off the 250 pump to Randall for some tune up and repair
work, and still have both 100HP's AND the bypass pump onsite. Our 1 month of bypass pump rental will likely
become 2 and hopefully only be 2.
Just a few FYI items this AM. Stay safe today, and dry if you can.
Zeb.
