On Thursday, October 3, 2019, Zach Thomas and Josh Brigham of the Raleigh Regional Office with
Division of Water Resources conducted a follow-up compliance evaluation inspection of the
treatment facilities located at the Hilltop Mobile Home Park. The purpose of this inspection was to
ensure compliance with the subject NPDES permit and evaluate if the requested repairs from the
12-7-2018 inspection had been completed. During the inspection, the presence and cooperation of
Mr. Paul Smith (ORC), Mr. Derek Hinds and yourself was helpful and appreciated.

visits in a binder for review.
2. A new bar screen has been fabricated and installed. At the time of inspection, everything
appeared to be in good working order with all flow passing through the treatment unit.
3. McFarland is contracted to pump and dispose of all sludge from the facility. Sludge is received
by the North Durham WRF located at 1900 East Club BIvd, Durham. The ORC stated that
McFarland recently visited on 10-1-2019 to collect sludge waste.
4. The previous inspection report stated, "At the time of inspection, neither of the two sets of audible

been working with Pete Duty and Associates to repair the alarms with no success. As of the 10-
3-2019 follow-up inspection, neither of the alarms had been repaired.
5. Both clarifiers appeared to have more sufficient settling throughout the column now that new
blowers have been added.
6. Notification to DWR of the operational status of the tertiary filters was required by 1-7-2019.
An email dated 12-26-2018 notified the RRO that the filters were placed online 12-17-2018.
Filters were in use at the time of the inspection. When the filters began to backwash, one of the
pumps was leaking. DWR staff asked that the part be evaluated and repaired promptly to avoid
any treatment issues.
7. A new generator was purchased and installed since the last inspection. The power was
switched off to the treatment facility and the generator operated properly under load.
8. In addition to evaluating the requested repairs, the Following items were noted during the
inspection:
a) Multiple locations of ground erosion around the treatment unit were observed. Please
ensure that these areas are addressed so that damage does not occur to the treatment
facility components.
b) Multiple trees have been limbed or cut to alleviate problems caused by leaf accumulation
within the treatment units. Please ensure that all State and Local government rules
regarding vegetation removal are followed if any work will occur in the future.
c) The flow meter was examined at the time of inspection and is past due for calibration as of
6-30-2019. Please ensure that the meter is calibrated and kept free from any debris that
will impede proper function.
Please respond in writing to items 4 and 8 within 30 days of receipt of this letter. If you have
questions or comments about the inspection, this report or the requirements to take corrective
action, please contact:
