Dear Sir or Madam:
JUL 3 0 2025
Since the last Quarterly Report dated April 25, 2025, the Town held a Progress Meeting on the
Wastewater Treatment Plant (W WTP) Improvements. Please see the attached minutes of the
meeting held on May 19, 2025.
Richard Davis, Wastewater Specialist with North Caroline Rural Water Association (NCRWA)
investigated and completed a Wastewater Treatment Plant Evaluation Report, dated May 30,
2025, as required under the terms of the SOC. A copy of the report is attached.
With regards to the aerators at the W WTP, 1 and 2 are being replaced as one is inoperative and
the other is failing. Aerator 7 is being replaced as the motor is broken. Aerator 5 is having some
wiring repaired.
The Rich Square Sewer Asset Inventory and Assessment project has begun to review and
inventory the town's sewer system. A significant amount of inflow and infiltration is coming into
the town's collection system. Several manholes have been identified in the ditch on Maggent
Lane that have been significantly damaged by mowing equipment. These manholes are major
inflow points and belong to Northampton County and were damaged by its mowing equipment. I
am in communication with the County on this matter to insure they will make the needed repairs
and avoid damage in the future.

Dear Ms. Manuel:
JUL i n .
Subject: SOC 90 Day Evaluation
EMC SOC WQ 524-002
NPDES NC0025437
Town of Rich Square
Northampton County
The Town of Rich Square holds permit NPDES NC0025437 for the operation and maintenance of
the town's wastewater treatment system. The town entered a Special Order by Consent (SOC)
with the Environmental Management Commission on March 26, 2025, to address noncompliance
issues associated with the noncompliance with permit limits.
As required by the conditions of the SOC, the Town is submitting a required 90-day treatment unit
investigation to provide the Department of Environmenta Quality and the Environmental
Management Commission of an evaluation of improvements to the treatment facility. This
information was formulated by the Wastewater Training & Technical Assistance division of the
North Carolina Rural Water Association, with the assistance of representative Richard Davis, and
is based on his visits to the facility, discussions with the staff and review of construction progress
information and a review of laboratory data.
• Solids Management Plan. Solids removal efforts were completed and measurements of
sludge depths in the lagoon made with a total of 148 dry tons of solids removed. It is
estimated that this effort resulted in the removal of 10-15% of the lagoon solids.
Measurements of the remaining lagoon depths have been made, and priority is being
determined for future sludge removal. The town is planning to review sources and methods
for future sludge removal and instituting a preliminary program to address solids inventory
and removal.
• Headworks Improvements: Equipment identified as part of the headworks is nearing
completion of installation and start-up and testing. Initial staff training has begun on the

equipment currently installed and will follow-up with the implementation of standard
operating procedures and related equipment maintenance service programs which will be
based on manufacturers guidance.
• Floating Aerators: Some aerators have been installed along with associated power cables.
Initial start-up testing and training has been completed along with the operations staff
involved in developing operations and maintenance procedures. Information obtained
from the equipment maintenance documents is being utilized to develop a written planned
program ensuring that documents maintenance history specific to each aerator are included
to provide for longevity and service life of the aerators. Presently, additional on -site
procedures to remove the accumulation of fibers the aerators, a major factor in service life
of the aerators is being developed to improve short term reliability and operation of the
floating aerators.
• Chemical Feed Systems and Chemical Storage. Evaluation of chemical storage tank
location is being considered along with plans to move two existing chemical tanks into
existing structures to mitigate climate effects. Strategies for developing a more constant
chemical purchase agreement are being evaluated to ensure continual chemical availability
without degradation to chemical quality. Initial training for the use of the equipment has
begun and operations staff are actively involved in adjusting chemical feed rates necessary
for adequate treatment and disinfection with flow changes. The town will partner with the
NC Rural Water Association for assistance and training in developing procedures to ensure
a strategic plan is created to address concerns related to safety, spill containment and
adequate chemical storage is attained on a continual basis.
Conclusion, this 90-day evaluation has evidenced the positive outcomes of construction planning
and operational activities needed to address deficiencies in the wastewater treatment facility.
Further completion of the current contract will provide an expected improvement to treatment
levels with a high level of confidence in meeting permitted performance. The town of Rich Square
and its staff are dedicated to making progress and improving the performance of its wastewater
treatment and protection of public health.
If you have any questions regarding this evaluation, please contact Victoria Newcombe at 252-
539-2315 (o) or 252-518-1365 (c).
Sincerely,
te
