Box 12626 Roanoke, VA 24027- SUBJECT: 4027 SUBJECT: Compliance Evaluation Inspection Associated Asphalt - Greensboro, NC NPDES Permit No. NCO074241 Guilford County Dear Mr. Thomson: ROY COOPER Governor MICHAEL S. REGAN Secretary S. JAY ZIMMERMAN Director RECEiVEDINCDEO)DWR MAH 2 8 Wa+terQualay Permiltdcgsecoor) On March 17, 2017, Min Xiao of this office met with Mr. Bruce Weaver to perform a Compliance Evaluation Inspection on the wastewater/stormwater discharge from the Associated Asphalt terminal located at 100 S. Chimney Rock Road. The inspection findings are detailed below and an inspection checklist is attached. I. Permit The NPDES permit has expired on August 31, 2016. The Water Quality Permitting Section has received your permit renewal application on March 4, 2016. II. Self -Monitoring Program Submittal of the electronic Discharge Monitoring Reports (eDMRs) began in January 2015. The monthly discharge monitoring reports (DMR's) were reviewed for the period January 2016 through December 2016. The facility was found to be in compliance with the NPDES effluent limits for the above period. In regards to the permit monitoring requirements, it was noted that all sampling was performed per the frequencies specified in the permit. III. Flow Measurement The permit requires episodic flow monitoring. The discharge volume from the retention pond is calculated by opening the locked release valve four turns and then timing the release (600 gpm). It was noted that no discharge occurred during the review months of January, March, April, June, September, November, December in 2016. IV. Facility Site Review The treatment system consists of a 1.0 MG retention pond. The retention pond is used to receive accumulated wastewater/stormwater from the bulk liquid storage containment, truck loading areas, boiler blowdown, and condensate. Effluent flow from the pond is calculated by opening a locked release valve four turns and then timing the release (600 gpm). The water'in the pond was observed to be clear. 450 West Hanes Mill Road, Suite 300, Winston-Salem, NC 27105 Phone: 336-776-9800 \ Internet: www.ncwaterouality.ors An Equal Opportunity \ Affirmative Action Employer— Made in part by recycled paper Page 2 March 17, 2017 VII. Records/Reports Only pH is measured onsite by Associated Asphalt staff. Other parameters are measured by Meritech, Inc. The facility does not possess a field parameter certification currently, which shall be obtained through Laboratory Certification Branch of NC DEQ. A comparison of,February and October 2016 DMR with the field records and laboratory results revealed that Flow, pH, Turbidity, TSS, Oil -Grease, and Benzene had been correctly transcribed. The unit'of Plieriol was reported in mg/L in Meritech's laboratory results, however, the data of Phenol were directly -put into DMR without converting the units from mg/L to ug/L. Please note the difference between these two units and correct this mistake in the following DMR's. VIII.. Effluent/Receiving Waters 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. Should you have any questions concerning this report, please contact Min Xiao or me at (336) 776 9800. Sincerely, 'V "r/Sherri V.

The unit of Phenol was reported in ma/L in Meritech's laboratory results, however, the data of Phenol were directly put into DMR without converting the units from mg/L to ug/L. This parameter is measured only for monitoring purpose (without a limit). An annual Acute Toxicity Test report was prepared for review.
