Re: Reply to Notice of Violation NOV-2021-PC-0229, Intent to Assess Civi: Penalties
Dear Mr. Vinson:
The Town of Clayton wou:d like to provide the following response to the NOV-2021-PC-0229, Intent to
Assess Civil Penalties received by the Town of Clayton, NC on April 21, 2021.
As previously reported the Town experienced a pipe fa:lure on the discharge side of the influent station,
the incident was discovered by the on ca I operator who was performing the weekend plant inspection
The operator contacted the ORC as required and informed the Water Sewer Maintenance Department
of the need to mobilize.
Theroot cause of the failure was a fissure in the twelve inch ductile iron pipe on the discharge side at
the influent pump stat'on. The line is located four feet below grade under a 480 volt cement duct bank
in a congested area. The area is located in one of the lower areas at the plant site and contains a great
deal of stone placed during the initial construct:on of the pump station.
The Town mobilized a crew of n.ne along with 2 vactor trucks, mini excavator, tandem dump truck and
various equipment transport vehicles. The repa r was especially challenging due to the location of the
break and soil conditions. The pump station eventually had to be turned off to allow for the safe repair
of the break due to soil conditions. Godwin pumps was contacted in an effort to mobilize a temporary
pumping scenario however, due to the diligence of the Town's water & sewer crew the leak was
repaired prior to mobilization of a bypass pump.
Remediation of the area occurred over a two day event. Crews removed spillage material from around
the area and disinfected the ground with lime. A pump was set up downstream of where the storm

water discharge enters the stream and crews flushed and pumped any materials that had deposited
during the event back into the facility. Overall the cost of the repa r and cleanup was $ 11,535.34. This
repair would have required an outside contractor several years ago without the Town's commitment to
the environment through capital funding for equipment and staffing The Town is currently evaluating
means to reduce the possibilities of having this type of failure to occur in the future
The Town continues to implement an aggressive Capital Improvements Plan that includes the huilding
and commissioning of a new 6.0 rngd water reclamation facility by December of 2023. The project
includesa new off -site plant, two transmission projects, and the decommissioning of the current facility.
Current estimates of the cost of the overall project is $120.000,000 The project represents to Town's
commitment to provide exceptional service through infrastructure replacement and the need to provide
for future growth. The new pump station scheduled to be built will have standby duty pumps,
emergency diesel pumps, backup generator and a bypass connection The Town has also spent an
estimated $1,100,000 to purchase two new vactor trucks, TV trailer, and a rubber tired back hoe in the
past five years for the maintenance of water and sewer lines
The Town of Clayton requests some consideration on the basis of our overall effort to reduce the
frequency and impacts of the inherit nature of maintaining water and sewer lines. This event would
have been very difficult to predict for any system, however we feel our response was very good
considering the timing and difficulty of the repair.
Please contact me directly at 919.553-1536 if you have any questions.
Sincerely
