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.

The ORC is completing log sheets for the facility and keeping additional information for site 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 Blvd, 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 or visual alarms were operational. Please return these alarms to operational status and provide a date when these were repaired."

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.
