VAN, DFR- se -IM C.YY S- JAY ZHV11v1E.RNLkN D-Trii:w RECEIVEDINCDEQID'A SEP 2 0 2016 Water Quality Permitting Section The North Carolina Division of Water Resources conducted an inspection of the Parkton WWTP on August 16, 2016. This inspection was conducted to verify that the facility is operating in compliance with the conditions and limitations specified in NPDES WW Permit No. NC0026921. A summary of the findings and comments noted during the inspection are provided in the enclosed copy of the inspection report. The Bioassay Compliance inspection was conducted by Division of Water Resources staff from the Fayetteville Regional Office. The following violation(s) were noted during the inspection: Inspection Area Description of !Violation Effluent Sampling Chronic Aquatic Toxicity "Fail' Result" State of North Carolina I Environmental Quality I Water Resources 225 Green Street, Suite 714, Fayetteville, NC 28301-5043 910-433-3300 Mr. McMillian Page 2 September 15, 2016 Comments ➢ A chronic toxicity sample was taken on August 16 and 18, 2016 and sent to the Division of Water Resources Aquatic Toxicity Laboratory (located on Reedy Creek Road in Raleigh, NC) for testing. These samples resulted in a "Fail Result" for the Chronic Toxicity Pass/Fail at 90%, and these results indicated that the effluent would be predicted to have a negative water quality impact on the receiving stream. The failure of this test was considered as a violation of the toxicity limitation specified in your NPDES Permit. The DWR laboratory indicated that the pH for the samples were 5.8 and 4.1. Both pH's were below the permitted limit of 6, however the 4.1 was significantly lower and could have contributed to the failure of this test. The conductivity for these samples were 528 micromhos/cm and 571 micromhos/cm. While the Parkton WWTP does not have a conductivity limit in their NPDES permit, these results are both above the 250 micromhos/cm limit that Waste Water Treatment Plants have if they have a limit. The high conductivity and the low pH's together could have been the cause for the failure. The following week, Mr. Tim Little, facility ORC, called the Fayetteville Regional Office to report high conductivity in the weekly sample that was taken on August 23, 2016. Mr. Little stated he would begin checking the wastewater collection system to see if he could locate the source of the high conductivity. Mr. Little also committed to testing the effluent pH more frequently to ensure the effluent was meeting permit compliance. ➢ It was noted during the inspection that the new bar screen, grit chamber, new chlorine contact chamber, and flow pacing equipment for chlorine were in operation. ➢ Maintenance records, ORC log, and laboratory data was up to date. 9 Laboratory records for the month of November 2015 and February 2016 were reviewed and no transcription errors were found. Remedial actions should have already been taken to correct this problem and prevent further occurrences in the future. The Division of Water Resources may pursue enforcement action for this and any additional violations of State law. To prevent further action, please respond in writing to this office within 30 days upon your receipt of this Notice of Violation regarding your plans or measures to be taken to address the indicated violations and other identified issues, if applicable. ➢ The FRO is offering to help with some process control testing for chronic toxicity if the town in interested. The testing will be done with the help of the Aquatic Laboratory.
