Inspection Summary
An inspection of the Village Oaks MHP WWTF and spray field was conducted on 07-25-2018. The facultative lagoon is
hydraulically connected to the storage lagoon and the freeboard was approximately 22". The lagoon embankments were well
maintained and the treatment area was secured with a fence and locked gate. Flow coming into the lagoon is tracked by
water meter readings of the MHP. This permit, WQ0002571, expires July 31, 2019. A reminder that a renewal application will
need to be submitted 6 months prior to the expiration date.
The following observations were made and require corrective actions to be in compliance with the permit:
1. Documentation of the calibration of the flow meter consisted of a tag that was not legible. More detailed documentation
needs to be provided that includes the date of calibration and percent from true flow. Please note, an accurate flow meter
along with a pressure gauge at the pump and another gauge at a spray head on the far side of the system, will allow the
facility to determine the amount applied and verify the relative accuracy using the specification chart for the spray heads.
2. There was insufficient pressure to rotate all of the spray heads and some spray heads were not spraying any effluent
during the inspection. The spray system needs to be maintained to adequately utilize the spray field and prevent ponding.
3. David Antinori is listed as the BORC for the facility. If this is not accurate, a certified operator needs to be assigned as
BORC by submitting a Operator Designation Form.
A Notice of Deficiency is being issued for the above observations. Please respond to the Wilmington Regional Office within
30 days outlining actions to address these issues.

Comment: There was insufficient pressure to rotate all of the sprav heads and some sprav heads were not
spraying any effluent during the inspection. Low pressure has been a problem at this facility and
has been documented on past inspection reports. The sprav system will need maintenance to
adequately utilize the spay field and prevent ponding. A more visible sign at the entrance of the
sprav field is recommended to prohibit public access.
