County Dear Mr Britt: PAT MCCRORY Governor DONALD R. VAN DER VAART Secretary S. JAY ZIMME.RMAN Director Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection conducted on 11/17/2015. The Compliance Evaluation Inspection was conducted by Mark Brantley, Environmental Program Consultant, of the Fayetteville Regional Office. The facility was found to be in Compliance with permit NC0086550: The cooperation' of Mr. Britt, facility ORC, and Mr. Kevin Taylor, facility back-up ORC was greatly appreciated. As.a reminder, preservation of the Waters of the State can only be achieved through consistent NPDES Permit compliance. Comments e Facility was clean and neat in appearance at the time of the inspection. • A Whole Effluent Toxicity test was collected at Outfall 001 from the Fairmont's 24-hour composite equipment on November 17 and 19, 2015 for use in.a chronic Ceriodaphnia Dubia pass/fail toxicity test. These samples were sent to the Division of Water Resources (AT) Laboratory (located on Reedy Creek Road. in Raleigh). The laboratory classified this test as an invalid test due to problems with the laboratory test. A test will be rescheduled for February 2016.. • Operators Togs and maintenance Togs are well kept. • Laboratory records for the month of July 2015 were compared to the monthly discharge report and no transcription errors were found.

Below is the. North Carolina Administrative Code concerning the flow proportional sampling: 15A NCAC 02B .0503 DEFINITIONS Unless the context otherwise requires, the terms used herein shall be as defined in G.S. 143-213 and as follows: (1) "Biological monitoring" shall mean the sampling or testing of the biological integrity of surface waters and measurements of impacts including accumulations of pollutants in tissue, toxicity monitoring, and characterization of instream biological populations. (4) "Composite sample" means: a sample gathered over a 24 hour period by continuous sampling or combining grab samples in such a manner as to result in a total sample which is representative of the wastewater discharge during the sample period. This sample may be obtained by methods given below, however, the Director may designate the most appropriate method, number and size of aliquots necessary and the time. interval between grab samples on a case -by -case basis. Samples may be collected manually or automatically: (a) Continuous - a single, continuous sample collected over a 24 hour period proportional to the rate of flow. (b) Constant time/variable volume - a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow measured at the timeof individual sample collection, or (c) Variable time/constant volume - a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at the treatment system, or (d) Constant time/constant volume - a series of grab samples of equal volume collected over a 24 hour period at a constant time interval. This method may be used in situations where effluent flow rates vary less -than 15 percent: -The grab -samples shall be taken at intervals -of - no greater than 20 minutes apart during any 24 hour period and must be of equal size and of no less than 100 milliliters. Use of this method requires prior approval by the Director. It does appear that the town has the necessary equipment to begin flow proportional sampling. The Fayetteville Regional Office recommends that the town contact the instrumentation company that calibrates the effluent flow meter for assistance in setting up the equipment. Mr. Britt Page 2 December Please respond in writing with a Plan. of Action on how the town plans to accomplish flow proportional sampling within 30 days of receipt of this letter. Please refer to the enclosed inspection report for additional observations and comments. If you or your staff have any questions, please call me at 910-433-3327.
