RE: Notice of Violation
Tracking Number: NOV — 2021—DV - 0185
Sanitary Sewer Overflows — February 2021
Collection System Permit No. WQCS00016
Albemarle Collection System
Stanly County
Dear Mr. Basinger,
The purpose of this letter is to provide additional information for the consideration in the above
referenced matter in accordance with your letter dated March 26, 2021 and received by the City of
Albemarle Collections ORC on April 19th, 2021. This matter relates to the sanitary sewer overflow and
lift station equipment failure that the City of Albemarle experienced during this time. This overflow is
associated with all night rain event and failure of a pump.
02/19/2021
Incident number 202100722 was caused by a large rain event along with pump failure and I&I from
Stanly County Collection System. To recap what happened during these hours, the high water alarm went
off around 7am on the above mentioned morning. On call personnel were dispatched to the call. Upon
arrival they noted that one pump was out and the one pump that was running was keeping up with flow at
the time. The ORC was called out and arrived at 7:30 checked things and the lift station seemed to be
holding its own. The ORC then made a call to Charles Underwood Pumps INC to bring a temporary
pump (skid pump) on site and order a new pump . They advised the ORC that they would be there by 12
noon and have things set up. During this time the ORC which is over the Distribution system got a call
that one leg of the raw water intake had blew out and that crews were going to shut that leg down and
isolate the leak . The ORC left to go check the raw water intake out and help get the situation under
control. During this time the ORC received a call form Michael Meilinger with NCDEQ who stated he
was on site at the lift station and it was about to overflow at the time the ORC called the Back up and
advised them to get the Vactor truck on site to stop or alleviate the possible SSO. The backup advised
ORC that they were currently finishing up on sewer main stoppage in Hwy 52 and that they would be
there as soon as possible. Shortly after this phone conversation ORC and back up arrived on site to find

out that the lift station had in fact created a small SSO while in route but by the time they arrived it had
stopped and caught back up with itself. This SSO was witnessed by NCDWQ staff that were on site. City
equipment arrived on site and started the process of evacuating from the wet well , Crews were able to
pump down the wet well with 4 loads to the point where the I&I from the county lift station had almost
caught up and slowed down enough to not threaten the capacity of the wet well. The ORC and Back up
then were advised by NCDWQ staff as to what to call the SSO in as and all parties came to an agreement
on the SSO amount. Crews then cleaned up area with city equipment and washed down wet well and
applied lime in affected area around wet well. Charles Underwood crew arrived on site around 1 and set
up skid pump to compensate for pump going out until they could get our new pump in.
I would also like to state that the City of Albemarle in the meantime has been working with LKC
Engineering along with Charles Underwood INC doing several draw down studies and also looking at the
sizing of the force main associated with this lift station. As of right now to help combat flow issues
coming from the county the City along with above mention contractors and engineers are looking at
upsizing the force main to pump more volume and will help the pumps run more efficiently
The City of Albemarle appreciates the opportunity to provide this information for consideration in this
matter. It is hoped that we will be received favorably. If there are any more questions or information that
is needed, please feel free to contact this office.
Sincerely,
