Subject: Compliance Evaluation Inspection
Quail Run Mobile Home Park
NPDES WW Permit No. NCO070033
Davidson County
Dear Permittee:
On April 4, 2023, Division of Water Resources (DWR) staff Jesse Barnes conducted a routine
compliance evaluation inspection at Quail Run Mobile Home Park in reference to NPDES permit
NC0070033. Jon Southern, Operator in Responsible Charge (ORC), was present during the
inspection. A review of the subject permit, required records, self -monitoring program, laboratory,
flow measurement, operations and maintenance, and effluent and upstream/downstream
sampling was completed. This review and inspection mostly reflected compliance with the subject
permit. Items of concern observed during the inspection are listed below.
Items of Concern
1.
Mr. Southern attested that the facility is now owned by 40 Oaks, rather than Frog Level
Industries, Inc, as listed on the permit. Additionally, the first attempt to deliver this report
via USPS was undeliverable according to the contact information previously provided.
Please provide updated ownership and contact information to the central permitting unit
by submitting the attached change of ownership form.
2.
A de -chlorination contact tank was observed during the inspection but is not listed in the
facility components in the subject permit.
3.
As noted in the most recent inspection, upstream sampling has still been conducted in a
tributary to Miller Creek rather than 100 ft upstream of the effluent outfall in Miller Creek.
Mr. Southern, being a new ORC, was unaware of the permit -specified upstream sampling
location. Once informed, he located an upstream sampling location and sent that
information to DWR via email. All required sampling is now conducted in compliance with
the subject permit.
4.
Ponding was observed in the sand filter, and the media may need to be replaced.
5.
Five septic tanks are listed in the subject permit components list, but Mr. Southern was not
aware of the exact location of all five tanks. Please locate and evaluate the condition of all
components of the treatment plant and ensure the description of the plant in the permit is
accurate. Mr. Southern was unsure if all septic tank audiovisual alarms were operational.

A
The chlorination and de -chlorination systems had four tubes leading to a flow -through box,
but the tubes were empty with tablets sitting in the box and treated wastewater flowing
through the box with the tablets. Mr. Southern explained that he does not use the tubes,
but rather places tablets directly into the bottom of the box where water flows through.
The tablet tubes should be repaired and used as designed to ensure sufficient disinfection
and de -chlorination.
Please be aware that the Division may take enforcement action against any permittee who fails
to comply with any requirement of their permit. Pursuant to NC General Statute (NCGS) 143-
215.6A, a civil penalty of not more than twenty-five thousand dollars ($25,000.00) may be
assessed against any person who violates or fails to act in accordance with the terms, conditions,
or requirements of any permit issued pursuant to G.S. 143-215.1.
If you have any questions or concerns, please do not hesitate to contact Jesse Barnes by phone
at 336-816-7351, or by email at [e-mail].

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The facility components were found to be as described in the permit. Mr. Southern attested that the
facility is now owned by 40 Oaks, rather than Frog Level Industries, Inc, as listed on the permit.
Please provide updated ownership information to the central permitting unit by submitting the
attached change of ownership form. During the inspection, a de -chlorination contact tank was
observed but is not listed in the facility components in the subject permit. The treatment facility is
restricted to the public via gated fence. The inspector was granted access to all requested areas for
inspection.
All required records were complete and available for review during the inspection, including DMRs,
laboratory analyses, chains of custody, visitation logs, and a copy of the subject permit.
Parameters analyzed by certified field laboratory Bell Enterprise (#5690) are dissolved oxygen,
temperature, and TRC. All other parameters are performed by certified contracted lab, Pace
Analytical.
Influent flow is monitored and estimated using the water meter provided and maintained by the City of
Winston-Salem that measures influent water supply to the mobile home park. Mr. Southern assumes
the meter is properly maintained by the City. The meter was not observed during the inspection.
Adequate storage is available for incoming wastewater in the event of a power outage of a typical
period of time. The permittee should consider installing a backup generator, installing connections for
a portable generator, and/or maintaining a contract with a portable generator provider in the event of
longer -term power outages.
Five septic tanks are listed in the subject permit components list, but Mr. Southern was not aware of
the exact location of all five tanks. Please locate and evaluate the condition of all components of the
treatment plant and ensure the description of the plant in the permit is accurate. The septic tanks Mr.
Southern is aware of are pumped approximately every four months and all records were available on
site during the inspection. Mr. Southern was not sure if all septic tank audiovisual alarms were
operational, but the facility has ample storage and no recent overflows.
The sand filter system appeared to be operating properly during the inspection. Some algal growth,
ponding, and sludge was noted on top of the sand, but not excessive in nature. Mr. Southern
explained that he has been slowly replacing the top few inches of sand over the past year as funds
and time allow. He was unaware of the last time the sand filter media was fully replaced. The sand
filter media may need to be replaced.
Both disinfection and de -chlorination tablet systems were inspected and the correct tablets were
being used. The chlorination and de -chlorination systems had four tubes leading to a flow -through
box, but the tubes were empty with tablets sitting in the box and treated wastewater flowing through
the box with the tablets. Mr. Southern explained that he does not use the tubes, but rather places
tablets directly into the bottom of the box where water flows through. The tablet tubes should be
repaired and used as designed to ensure sufficient disinfection and de -chlorination.
Effluent samples are grabbed from the end of the de -chlorination contact well, just before entry to the
effluent pipe. The effluent outfall pipe was not inspected due to safety/access concerns and time
constraints. As noted in the most recent inspection, upstream sampling has still been conducted in a
tributary to Miller Creek rather than 100 ft upstream of the effluent outfall in Miller Creek. Mr.
Southern, being a new ORC, was unaware of the permit -specified upstream sampling location. Once
informed, he located an upstream sampling location and sent that information to DWR via email. All
required sampling is now conducted in compliance with the subject permit.
