Permitting Section
Dear Mr. Thomson:
On April 13, 2018, Jenny Graznak of this office met with Bruce Weaver to perform a Compliance
Evaluation Inspection on the stormwater discharge from the Associated Asphalt terminal located
at 100 South Chimney Rock Road. The inspection findings are detailed below and an inspection
checklist is attached.
1. Permit
The permit expired on August 31, 2016. Please continue to operate under the old permit until you
receive your new permit from the Division.
2. Self-Monitoring Program
A review of the monthly Discharge Monitoring Reports (DMRs) for the period January 2017
through February 2018 showed one violation of permit limits in June 2017. This violation of the
Total Suspended Solids permit limit was due to heavy rain when the facility had to release water
from the pond. This violation was previously addressed in separate correspondence from this
office. Regarding the permit monitoring requirements, it was noted that all sampling was
performed per the frequencies specified in the permit during this time.
3. Flow Measurement
The permit requires episodic flow monitoring. The discharge volume from the retention pond is
calculated with a formula by opening the locked release valve for four complete turns and then
timing the release. The facility only discharges from the pond when necessary.
4.Facility Site Review
The stormwater treatment system consists of a 1,000,000-gallon retention pond with a locked
effluent release valve. The retention pond receives wastewater/stormwater from the bulk liquid
storage containment,truck loading areas,boiler blowdown and condensate.

5. Records/Reports
A review of the on-site files at the facility showed that the records were being maintained according
to the permit. Meritech performs all laboratory analyses except for pH, which is measured by
Associated Asphalt staff. The facility holds field parameter certification#5691 for pH.
6. Effluent/Receiving Waters
The system discharges into a ditch at the perimeter fence. The effluent eventually reaches a
tributary of the East Fork Deep River, class WS-IV* waters of the Cape Fear River Basin. No
effluent was being discharged on the day of the inspection.
Your efforts to comply with the permit are appreciated. Should you have any questions concerning
this report, please contact Jenny Graznak or me at(336) 776-9800.
Sincerely,
Nil
