On Thursday, February 8, 2018, Vanessa Manuel of the Raleigh Regional Office conducted a
compliance evaluation inspection of the treatment facilities located at the Middlesex Water Well
#4 Water Treatment Plant (WTP). The purpose of this inspection was to ensure compliance with
the subject NPDES permit During the inspection, the presence and cooperation of William
Lamm, Operator in Responsible Charge (ORC), and James Liles, Public Works Director, were
helpful and appreciated
The Middlesex Water Well #4 WTP is located at 10921 East Finch Street in Nash County. The
water treatment plant provides treated water to its residents and community The treatment
facility is classified as a Physical/Chemical-1 wastewater treatment plant that treats
backwash/rinse wastewater from sand filtration units and is authorized to discharge the treated
wastewater through outfall 001 into an unnamed tributary to Turkey Creek, a waterbody
classified as C, Nutrient Sensitive waters within the Neuse River Basin.
This NPDES compliance evaluation inspection consisted of the following
• Review of the NPDES permit,
• Review of the owner/facility information;
• Review of December 2015 — November 2017 monitoring data;
• Review of January 2015 — December 2017 compliance history,
• On-site inspection of the wastewater treatment units; and
• On-site inspection of the discharge outfall
Findings during the pre -inspection file review were as follows.
The current NPDES perms was issued effective November 1, 2013, and will expire May 31,
2018., On November 1, 2017, the Division received the town's permit renewal application
for the Middlesex Water Well 44 WTP. The Division is in the process of renewing this
NPDES permit.

2. As listed in the subject permit, the treatment components include liquid chlorination, 2 sand
filter tanks, a backwash meter, a potable water air stripper system, 2 wastewater drying beds
and tablet dechlorination.
3. Beginning December 21, 2016, EPA's NPDES Electronic Reporting Rule requires permittees
to submit their discharge monitoring reports (DMRs) electronically, instead of on paper The
first DMR the Division received electronically from the permittee was for July 2016. To
learn more about the eDMR system, please visit the Division's eDMR website at
https //deq ne.gov/about/divisions/water-resources/edmr.
�. For the review period January 2015 — December 2017, the following unaddressed violation
was detected: Late/Missing DMR for April 2016 Self-monitoring reports are due to the
Division no later than the last calendar day of the month following the completed reporting
period. The Division received the town's April 2016 DMR on June 27, 2016. The following
enforcement action was issued to the town during the review period: Notice of Deficiency
dated March 1, 2016, for failing to monitor and report Total Residual Chlorine during
September 2015 as required by the NPDES permit
Findings during the inspection were as follows -
5. The operator's log and supporting analytical documentation were consistent and up to date.
6. The inspector compared the August 2016 and March 2017 DMR data against the ORC's
bench lab data and Environment 1 analytical results On the February 2016 eDMR, the unit
of measure for the Iron data is mg/L. The associated analytical lab data reflects the unit of
measure as µg/L. Please submit an amended eDMR for August 2016 to reflect the
correct unit of measure. No other discrepancies were noted.
7. The observed treatment units were as described in the NPDES permit (see item 2 above)
The treatment units were maintained and no apparent issues of concern were noted
8. There was no discharge from the treatment facility at the time of the inspection The ORC
stated that prior to releasing treated effluent, dechlorination tablets are added to the
dechlorination tube. The effluent discharge pipe is located in the culvert ditch in front of the
treatment plant No detrimental impacts to the unnamed tributary were observed.
If you have questions or comments about the inspection, this report or the requirements to take
ccrrective action (if applicable), please coact Vanessa Manuel at 919-791-4255 or via email at
