Easley, Governor March 5, 2003 CERTIFIED MAIL RETURN RECEIPT REQUESTED The Honorable Ann B. Slaughter Mayor, City of Laurinburg PO Box 249 Laurinburg, NC 28352 SUBJECT: NOTICE OF VIOLATION Reconnaissance Inspection _ City of Laurinburg Wastewater Treatment Facility NPDES Permit No. NC20656 Scotland County William G. Ross, Jr., Secretary Alan Klimek, P.E., Director Division of Water Quality Dear Mayor Slaughter: On February 18, 2003, Don Register and Belinda Henson, of the Fayetteville Regional Office, Division of Water Quality, visited the Leith Creek Wastewater Treatment Facility. After speaking with Mr. Ricky Odum, Back-up ORC, staff proceeded to inspect the recently rebuilt secondary clarifiers. The chlorine contact chamber was also inspected and staff witnessed activated sludge solids flowing through the unit into the effluent channel (see below). Staff, at that time, proceeded to find Mr. Odum to alert him of the solids washout and to stop it immediately. Fayetteville Regional Office . . •u_ a_.L n__ r nooni cnno Mayor Slaughter Page 2 March 5, 2003 It is the opinion of this office that the discharge of solids in this manner is a violation of your NPDES Permit Part II Section C. 2 that states: Proper Operation and Maintenance- "The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit". • While waiting for the violation to stop, Mr. Robert Ellis, the operator in responsible charge (ORC) of the facility arrived on site. When he was asked the reason for the violation, he commented that it must be the recent rain in the area that was washing' the solids out. The clarifier overflow rates did not appear to be excessive, which would indicate high flows. Upon request, Ricky Odum, checked the sludge blanket depth of the #1 clairifier (which was not overflowing the weirs) and it appeared to be a nine foot blanket in a 12 ft. deep sidewall depth. The #2 clarifier, the one overflowing solids at that particular time, appeared to be overloaded with solids or the solids had a settling problem. Judging by the requested flow data received for the week of the violation, the flow did not appear to be too high. The day of the violation, the total daily flow was measured at 3.557 MGD (permitted flow.4 MGD) and the 24 hour effluent composite sample measured at 650 mg/1 for the total suspended solids (620 mg/1 over the Town's limit of 30 mg/1). This office is requesting the following data to help determine the source(s) of the problem noted. Typically, problems can be generally categorized as design or operational. We ask that you provide the following information for the, months of September 2002 through February 2003 on or before April 15, 2003: 1. The dates of the usage of the equalization basin and the flows (MGD) that was diverted to the EQ basin. 2. Copies of weekly circular flow charts. 3. Each of the aeration basin (MLTSS) mixed liquor total suspended solids analysis in mg/1. 4. The clarifier blanket readings recorded for each clarifier. 5. The date and the number cif gallons wasted to the digester. 6. The level of the digester each day. 7. The biosolids land application events for 2002 and the volume applied during each event. 8. The calculation(s) used to determine sludge wasting. 9. A plan of action to prevent discharges of similar nature from reoccurring. In addition to the above, we would like to draw your attention to the attached Compliance Biomonitoring Inspection for the inspection conducted the week of March 26, 2001. Please note during that inspection, regional staff observed a similar discharge of high solids and a Notice of Violation was also forwarded at that time. By documenting two (2) occurrences where waste solids were leaving the municipal wastewater treatment facility in a manner inconsistent withthe permit, this office has no choice but to consider this a reoccurring problem. As previously requested, we ask that you provide a plan of action that will prevent further violations of this nature. Mayor Slaughter Page 3 March 5, 2003 Please be advised that this notice does not prevent the Division of Water Quality from taking enforcement actions for the violation(s) noted or any violation past or future. Your response to this letter will be considered in determining if further action, to include civil penalties, will be warranted. Should you have any questions regarding this matter, please do not hesitate to contact me at 910-486- 1541. Paul E.

COMPLIANCE BIOMONITORING INSPECTION City of Laurinburg Wastewater Treatment Plant NPDES Permit No. NC0020656 Scotland County Dear Ms. Slaughter: Enclosed you will . find a. copy of the Compliance Biomonitoring Inspection report for the inspection conducted the week of March 26, 2001. The inspection included the same objectives as that of a routine Compliance Evaluation Inspection (conducted•on March 26, 2001) plus an Aquatic Toxicity •(AT) test to evaluate the. biological effect of the facility's discharge on test organisms. • As part of the inspection a tour •of the Wastewater Treatment Plant Was conducted. All observations and recommendations are in Part D: Summary of Findings/Comments of this inspection report. A 24-hour 001 effluent composite.sample was collected at your facility on March 27 and on March. 30. s The aquatic toxicity samples were sent to the Division of•Water Quality Aquatic Toxicology Laboratory (located on Reedy Creek Road in Raleigh). • The chronic Ceriodaphnia. dubia 31% pass/fail toxicity test using these samples resulted in a Pass, indicating that the effluent would not be predicted to have water quality impacts on the receiving waters. Additionally, on March 27, .the 24-hour Outfall 001 effluent was sampledfor. the following parameters:. Biochemical Oxygen Demand (BOD), Ammonia as nitrogen, Total Kjeldahl Nitrogen, Nitrite plus Nitrate as ,nitrogen, Total. Phosphorus, Copper, and Zinc: On Friday, March 30, a TSS sample was collected from DWQ"s composite sample (collected from noon on March 29`" to noon on March 30th and quickly processed by the DWQ Laboratory in Raleigh); the TSS result was 370 mg/L (which does not agree with the result of the TSS for the composite collected by your facility for the approximate time period of 8:30 AM on March 29th to 8:30 AM on March 30`h). That TSS result was 58 mg/L.. On April 4ththe 24-hour composite sample collected by your facility during the time period of 8:30 AM on Tuesday, April 3d to 8:30 AM on Wednesday April 4th, was split. A TSS sample and a • BOD sample were sent to our DWQ laboratory. The laboratory results of the pending chemistry analyses will be forwarded to you when they. are completed by the Division of Water Quality Chemistry Laboratory, located on Reedy Creek Roadin Raleigh. 225 GREEN STREET - SUITE 714 / SYSTEL BUILDING / FAYETTEVILLE, NC 28301-5043 PHONE (910) 486-1541 FAX (910) 486-0707 WWW.ENR.STATE.NC.USiFNR! AN EQUAL OPPORTUNITY / AFFIRMATIVE ACTION EMPLOYER - 50% RECYCLED/10% POST CONSUMER PAPER DENR TOLL FREE HOTLINE: 1-877-623-6748 copy of the following information was left with Ricky Odum: 1. NPDES Compliance Reminders, 2. Vector Attraction and Pathogens - Class B, 3. An invitation for no cost Operator Wastewater Training on April 6, 2001 at the DWQ-Fayetteville Regional Office (a FAX of this invitation was also sent to Robert Ellis). Based on observations and sample taken, this office considers the Town. of Laurinburg in violation of NPDES permit Part IL Section C. 2. Proper Operation and Maintenance — permittee shall at all times properly operate. and maintain all facilities and systemsof treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions ofthis permit." The following itemsare addressed in this report as violations of the NPDES permit: 1) On the day of the inspection; Monday, March 26,. solids at clarifier #1 were overflowing into the chlorine contact chamber. Solids.had not been wasted since January 2001. 2) Digester capacity was full of solids through the entire week of March 26. 3) The TSS sample, collected from noon on Thursday (March 29) to noon on Friday (March '30) by DWQ, was 370 mg/L. 4) On Friday, March 30, condoms were floating in the chlorine contact chamber: 5) The chlorine contact chamber. was not properly maintained. The walls need immediate repair. This office is very concerned about the solids inventory of the WWTP: We feel that such inventory had reached a critical level due to the reported MLSS of between 5580 to 5880 mg/L. It is our understanding that your target MLSS is 2500. mg/L and that by not disposing of waste residuals (land applying) in a timely manner had resulted in the excessive solids observed and measured leaving your facility: We are requesting that your facility empty your digesters on a more frequent basis. You are asked to perform and document weekly monitoring of the sludge depth in the chlorine contact chambers until further notice. This data will be reviewed during future inspections. You are asked to send a response letter to this office within ten (10) days of receiving this report with a timeline for fixing the holes in the walls of the chlorine contact chamber. The response letter should also address the corrective action(s) that will be taken to eliminate the excessive sludge in the clarifiers; chlorine contact chambers, and digesters:. •Mayor Slaughter Page 3:.

SECTION D: SUMMARY OF FINDINGS/COMMENTS: _ PLANT TOUR--- 1. The facility has influent and effluent flow meters. The effluent flow is used for reporting. 2... The effluent composite sampler is flow proportional (constant volume/variable time), sampling every 50,000 gallons. It has been flowproportional for approximately five years. 3. The automatic climber bar screen has not been operational for three to four weeks (waiting for worm gear replacement items). Screenings go to the Scotland County Landfill. 4. The effluent composite sampler temperature was 5 degrees Celsius. 5. The grit removal system was operational. All grit goes to the Scotland County Landfill. 6. There is a workorder to replace the rails in the influent pump station. 7. The generator at the influent pump station is tested once per month. 8. Influent pumps are tested daily (each morning). 9. The ultrasonic flow -measuring device was installed in November 2000. 10. Land application will occur next week, Monday April 2, at the LMAC land application site. They will remove 700,000 gallons. Both of the aerobic digesters are full. 11. Launders of the clarifiers are cleaned daily. 12. In the winter, it takes approximately 2 to 3 months to dry sludge in the drying beds.. In the summer, it takes approximately 1 month. 13. Solids from the large and small digesters are land applied; solids from the small digester are applied to the drying beds. 14. Routine plant maintenance includes changing the oil in the aerators annually, and inspecting the pump impellers once every 3 months. Mayor Slaughter Page 6 April 17, 2001 15.

Climbing Mechanical Bar Screen is not in operation due to gearbox. repair (waiting for the main drive worm gear replacement items). This has not caused compliance problems. • 17. During the inspection the back-up ORC initiated cleaning of Contact Basin #1, followed by #2. Normally, the chlorine contact basins are cleaned out once per month. 18. Two of the walls of Chlorine Contact Basin #1 areeroded completely through at the surface. and one wall of Chlorine Contact Basin #2 is also eroded badly. Mayor Slaughter Page 7 April 17, 2001 LABORATORY TOUR -- Laboratory parameters that are analyzed on site: pH, Total Residual Chlorine, Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), Fecal Coliform,.Dissolved Oxygen, Conductivity, Ammonia Nitrogen, and temperature Metals (Hg, Cu, and Zn), Total Nitrogen (NH3, NO2; NO3, and TKN) and Total Phosphorus are sent to Oxford Laboratories, Inc: Chronic Toxicity is analyzed at Burlington Research.

An NIST crosscheck of all of the thermometers is performed and documentedannuaiiy. 9. The YSI Model 5100 is used for measuring the IDO and FDO of the BOD. The membrane is changed every three weeks. 10. The BOD GGA standard is purchased from North Central Laboratory. RECORDKEEPING:AND REPORTING: Eighty-four DMR data points from December 2000 were crosschecked with the laboratory bench. All data points were in agreement. Slaughter Page 8 April 17, 2001 RECOMMENDATIONS--- 1. Recommend that, in order to calculate the % error, the calibration. report sheet of the ultrasonic flowmeter at the Parshall Flume have the ultrasonic's reading beforeand after calibration, and the Parshall Flume's head measurement (in inches at the ultrasonic flowmeter location). According to 15A NCAC 2B .0505 (b) (1): "Devices selected shall be capable of measuring flows with a maximum deviation of less than 10 percent from true discharge.v.olumes. Flow, measurement devices shall be accurately calibrated at a minimum of once per year and :Maintained to ensure that the accuracy of the measurements are consistent with the accepted capability of that type of device.".:;-- .. 2. Remind. the facility that the following parameters are to be run on a grab sample: Chlorine, pH, Dissolved Oxygen, and Fecal. Coliform.. . . ' • - 3. Require that the pH, dissolved oxygen; and chlorine analyses be performed within fifteen minutes of collection as according to 40 CFR 136, page 29, Table II ---Required Containers, Preservation Techniques, and Holding Times: `Analyze immediately' usually means within 15 minutes or less of sample collection." .4. Recommend that the chlorine contact chamber be cleaned out when the sludge depth is no greater than one foot deep in the chamber. 5. Suggest that your facility empty the digesters on a quarterly basis to minimize the solids in the plant. 6. Require that your facility perform and. document weekly monitoring of the sludge depth in the chlorine contact chambers. ' • . -` 7. Require that your facility send this office a response letter within ten days of receiving this report addressing a timeline for fixing the holes .in the walls of the chlorine contact chamber and also addressing the corrective actions thatwill be taken to eliminate the excessive sludge in the clarifiers, chlorine contact chambers, and the digesters. ` 8. Require that your laboratory10 pH buffer be replaced because it has exceeded the expiration date.. .. .• 9. Since the effluent composite sample refrigerator temperature was:5 degrees Celsius, recommend that samples be collected, transported, and stored as according to the official storage temperature requirement published in 40 CFR Part 136.3(e), Table II. The acceptable temperature range is 0 to 4 degrees Centigrade. . However, the sample must not be frozen, especially for a biological sample. -The intent of cooling samples to 4 degrees Centigrade is to minimize any biological and chemical reactions such that the integrity of the sample is not compromised.
