NCO023353 I11 12I 16/08/29 117 18 1,1 Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) Enclosed you will find a copy of the Compliance Evaluation Inspection report for the routine inspection that was conducted on August 29, 2016 by Mark Brantley, Environmental Program Consultant and Johnathan Watts, Environmental Specialist of the Fayetteville Regional Office. The purpose of the inspection was to evaluate compliance with the requirements of the Wastewater General Permit NC0023353. As part of the inspection, a tour of the plant was conducted and weekly monitoring sample records were examined from March 2016 to April 2016. On the day of the inspection, this facility was found to be in compliance with the requirements of the permit. You are commended for your initiative and proactive approach for the documentation and on site monitoring. I appreciate the time and professional courtesy that you and Timothy Frush, Public Works Director, extended during the inspection. No additional response is necessary from your office concerning this report. If you have any questions, please feel free to contact me at (9 10) 433-3322. The White Lake WWTP, located at 90 East William St. Elizabethtown NC, produces discharge of treated effluent from a biological water pollution control treatment system, which consists of a Lagoon divided into 4 cells. All documentation records and log books appeared to be complete and current with provisions of the permit. All data appeared to correspond with DMR's. Effluent Flow Meter was Calibrated on May 26, 2016 and verification of the Chlorine meter calibration curve was performed on April 1, 2016. The Vortex Grit Chamber is currently defective and has been out of service since 2006, according to past inspections. It was determined that as a result of the algae bloom, there was green discoloration observed in the effluent, however barley straw is used to control growth. As stated from the previous inspection on August 8, 2013, "During the inspection of the chlorine contact chamber, a hole was noted in the baffle wall just before the effluent weir. This hole could allow some short circuiting." It is strongly recommended that a timeline and plan of action be submitted to perform repairs on chlorine contact chamber as baffles are critical for the efficient performance in improving the amount of chlorine contact time with fecal coliforms and possible contamination with pathogens. Restoring the chlorine contact chamber could reduce operation and maintenance activities and may ultimately increase reliability for achieving permit compliance. Based on conversations with Mr. Timothy Frush, progress towards these repairs are being made. Page# Permit: NCO023353 Owner -Facility white Lake WWTP Inspection Date. 08/29/2016 Inspection Type.
