L Permit
Permitting Section
The current permit became effective October 1, 2016 and will expire on June 30, 2021. A copy of the
permit was. not available during the inspection. Please make sure that the operator has a copy of the
most recent permit with his records.
2. Self -Monitoring Program'
The Discharge Monitoring Reports (DMRs) were reviewed for the period February 2017 through
March 2018. There were limit violations April, May, and October 2017, and they are summarized in
an attached list. These violations were addressed in separate correspondence from this office. All
sampling during this time appears to have been performed per the frequencies specified in the permit.
A
3. Flow Measurement
The permit requires weekly instantaneous flow monitoring. The effluent flow is manually measured
using the v -notch weir in the contact chamber.
4. Sludge Handling and Disposal
Solids are removed approximately every 6 weeks from the in -ground digester by Carolina Septic Tank
Company. The owner maintains the receipts from these services.
**5. Operations and Maintenance
This treatment system is showing significant signs of age and wear. The ladder to climb on top
of the treatment system is severely rusted and potentially unsafe for the operator and inspector.
The walkway is also severely rusted. The in -ground digester appears to be caving in to some
degree. The bar screen fell off the system at some point and has not been replaced, so the operator
manually removes solids. These issues should be addressed soon before they impact treatment.

6. Facilitv Site Review
The existing wastewater treatment system consists of the following: a single -train aboveground
package plant with flow splitter box (split between aeration basin and influent pump station to control
the flow), aeration basin, secondary clarifier, tablet chlorinator box (no tubes), contact chamber, tablet
dechlorination tubes and effluent discharge pipe. The old in -ground package plant is used for sludge
holding and is not aerated.
6. Records/Reports
A review of the operator's logs indicated that records are being maintained according to the permit. A
comparison of the September 2017 DMR with the corresponding operator records and certified
laboratory data sheets from Pace Analytical showed that all values were properly transcribed onto the
DMR.
7. Effluent/Receiving Waters
The system discharges into Little Alamance Creek, classified WS -IV NSW waters in the Cape Fear
River Basin. The effluent was observed to be clear during the inspection.
Should you have any questions concerning this report, please contact Jenny Graznak or me at (336)
