VAN DER VAART Secretary S. JAY ZIMMERMAN Director MAY _ 9 2016 1tj'�014,IRAT1Ui P4QC�S�I,VG UNIT NPDES Compliance Sampling Inspection NPDES Wastewater Discharge Permit No. NC00_034_25- Person County Dear Mr. Thacker: On March 1, 2016, Autumn Romanski and Cheng Zhang of the Raleigh Regional Office conducted a Compliance Sampling Inspection at the Roxboro Steam Electric Plant. The effluent sampling results were sent to the Division of Water Resources Laboratory and qualified lab results were received on April 18, 2016, which extended the inspection completion date noted on the EPA Inspection Report. We greatly appreciated the cooperation and assistance provided by Mr. Shannon Langley, Mr. Robert Howard, and Plant Staff to complete the inspection and sampling. The facility and the sampling results were in compliance with the permit requirements reviewed the day of this inspection. No response to this inspection is required. The complete compliance inspection report is attached. The following is a list of the site observations. 1. The Wastewater Discharge Treatments are classified as a Class PC- 1 Wastewater Plant. Your NPDES Individual Wastewater permit became effective July 1, 2009 and expired on December 31, 2012. 2. The Primary ORC is Eric Satterwhite, a PC -1 (certification number #985810) NC Certified Operator. There are several backup operators, all hold a PC -1 operator certification. The ORC logbook, lab results, chain of custody forms, and DMR's were readily available and in good order for review. The DMR month of December 2015 was reviewed with no discrepancies found. The staff should be commended as the facility has had no Notice of Deficiency or Violation issued in the last 12 months, and no Civil Penalty assessments. State of North Carolina I Environmental Quality I Water Resources 1628 Mail Service Center I Raleigh, North Carolina 27609-1628 919 7914200 3. The sampling techniques, CST Checklist, and a brief lab inspection checklist was completed. The facility was compliant with the checklist requirements reviewed over the days of this sampling inspection. The checklists are attached. 4. The Roxboro Plant holds NC Field Parameter Certification #5080 for pH and Temperature. The Roxboro Plant also used NC Certified Lab Pace Analytical through 2015. 5. The DWR conducted grab and composite effluent sampling at NPDES Effluent Outfall 003 and grab sampling at NPDES Effluent Outfall 006 over the days of the site visit. The DWR Lab results are listed below: Recent Average Flow reported in February 2016 for outfall 003 was 456.5 MGD and 0.79 MGD for outfall 006. Flow at both outfalls observed the days of the inspection were clear and free of solids The DWR Lab analyte results are attached to this inspection report and summarized in the tables below. Outfall 003 Analyte Result TSS Undetected at 6.2 mg/1 Arsenic Undetected at 2.0 ug/L NH3 as N 0 02 mg/L NO2 + NO3 as N 0.23 mg/L Total Phosphorus 0.05 mg/L Total Kjeldahl N as N 0 18 mg/L Outfall 006 Analyte Result TSS 1.8 mg/L There are currently no limits in the NPDES permit at Outfall 003 except in the case of chlorine addition in which a TRC limit of 200 ug/L is in effect. There are internal outfall limits for Oil and Grease and TSS at Outfall 002, but outfall 002 and other internal outfalls were not sampled as part of this inspection. The results showed the facility was in compliance with the NPDES permit TSS limit of 50 mg/L at Outfall 006. The Toxicity test results were forwarded in a separate letter and were Passes. 21 Page If you have questions, please contact Autumn Romanski at 919-791-4255 c Autumn.Romanski@ncdenr.gov. incerel , Danny Smith Raleigh Regional Operations Supervisor Cc: Enclosures RRO-WQROS DWR- Central Files via e-mail at Ec: shannon.langleygduke-energy.com; robert.howard@duke-energy.com 3 1 P a g e United States Environmental Protection Agency Fort Approved EPA Washington, D C 20460 OMB No 2040-0057 Water Compliance Inspection Report Approval expires 8-31-98 Section A National Data System Coding (i e, PCS) Transaction Code NPDES yr/mo/day Inspection Type Inspector Fac Type 1 2 15 I 3 I N00003425 111 12 16/04/18 17 181 o 1 19 L G I 201 I =1 211'-1 1 1 1 1 1 1 1 1 11 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 I 1 1 1 1 1 11 1 1 1 1 166 Inspection Work Days Facility Self -Monitoring Evaluation Rating B1 QA Reserved 72 LJ 73 I74 7511 I I I I 80 67 70LJ 71 itJ Section B Facility Data Name and Location of Facility Inspected (For Industrial Users discharging to POTW, also include Entry Time/Date Permit Effective Date POTW name and NPDES permit Number) 09 30AM 16/04/18 09/07/01 Roxboro Steam Electric Power Plant Exit Time/Date Permit Expiration Date 1700 Dunnaway Rd Semora NC 27343 03 20PM 16/04/18 12/03/31 Name(s) of Onsite Representative(s)/Titles(s)/Phone and Fax Number(s) Other Facility Data /// Ronald D Easley/ORC/336-597-7332/ Name, Address of Responsible Official/Title/Phone and Fax Number Contacted William J Thacker, 1700 Dunnaway Rd Semora NC 27343/Plant Manager/336-597-6101/ No Section C Areas Evaluated During Inspection (Check only those areas evaluated) Permit Flow Measurement Operations & Maintenance N Records/Reports Self-Monitonng Program Sludge Handling Disposal Effluent/Receiving Waters Section D Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) (See attachment summary) Name(s) and Signature(s) of Inspector(s) Agency/Office/Phone and Fax Numbers Date Cheng Zhang �� .� _ RRO WQH919-791-4200/ !
