I talked to the director of the center yesterday and he still has no idea what Dewberry (their engineers) will present. I think they plan to do little or nothing due to a stretch of compliance even though the plant is easily upset by one running toilet. If they pursue this line, I plan to ask Ken to require them to do composite sampling and more frequent sampling than weekly. They pull samples between 7:30 AM and 8 AM. I will also place samplers at their discharge and run a tox test. The effluent is consistently cloudy from what the RRO has seen on visits. Thanks for your help and see you tomarrow around 8:30. -7(4-4 9\11 June 18, 2002 Mr. Kenneth Schuster Water Quality Regional Supervisor Point Source Compliance/Enforcement Unit Division of Water Quality P.O. Box 29535 Raleigh, North Carolina 27626-0535 REF: Notice of Violation Show Cause Meeting Compliance Evaluation Inspection Kittrell Job Corps Center WWTP NPDES Permit No. NC0029131 Vance County Dear Mr. Schuster: In response to the Compliance Evaluation Inspection Report of May 21, 2002 per your direction to respond to inspection items comments and/or recommendations #s 4, 5, 6, 7, 9, 11, 15 and #16 respectively, the following responses are submitted. item #4. An ORC log is kept in accordance with the requirements of 15A NCAC 2B .0506(c) (3). However, a daily calibration log of the pH, residual chlorine, and dissolved oxygen meters is not being kept which is a violation. Please ensure that these logs are created and utilized every time a meter is used for reporting data on the Discharge Monthly Report (DMR). Response: Our calibration of our pH and dissolved oxygen meters are normally kept on our benchsheets themselves. We have had problems with our 4.0 pH buffer solution being read by our meter. We have purchased a new pH probe (received June 17, 2002) to remedy this problem. Our pocket colorimeter was factory calibrated, however if we need to calibrate the meter each time it is used, we will order reagents to prepare a known chlorine standard solution. Our dissolved oxygen meter is calibrated in water saturated air. We calibrate this instrument using barometric pressure, altitude, and salinity. This was not recorded on some of our bench sheets. We will procure a separate notebook for each of these instrument and calibration records will be clearly recorded for each. Inspection Response Page 2 Item #5. Mr. Matthews stated during the inspection that the pH meter would not read the 4.0 buffer and the meter had recently been returned after being repaired. It was noted that, in the past, the pH meter was calibrated with pH buffers 4.0, 7.0 and 10.0. All field parameters that are measured with a meter must have a three point calibration. It is recommended that a 4.0 and 10.0 pH buffer be utilized to calibrate the meter and a 7.0 pH buffer be used to check the calibration. The meter reading for the 4.0, 10.0 and 7.0 must be recorded in a log. Conductivity is also reported by field meter and must employ a three point buffer calibration that is recorded in a log. In addition, all buffers must have an expiration date noted on the bottle. Dissolved oxygen is determined by air calibration and also must be recorded in a log along with a check of calibration accuracy. Please state the facility's remedy for these concerns. Response: We have purchased a new pH probe (received June 17, 2002) and we will calibrate the meter using a 4.0 and 10.0 pH buffer solution. We will then check the calibration with a 7.0 pH buffer solution. We will then check the calibration with a 7.0 pH buffer. We do have all of these buffer solutions on site, but the factory did not record an expiration date on the containers. ORC will call Hach (manufacturer) to find out what the expiration date for our buffers are and record it on the containers. We do not conduct our own conductivity recording or testing. This parameter is collected by us and sent to Tritest Laboratory for testing weekly. Results for the weekly tests are maintained in a log located at the WWTP. Item #6. The effluent was cloudy in appearance and appeared to have excess solids suspended in it. Please state what the facility plans are to improve the effluent quality. Response: The effluent does get cloudy from time to time. On the day of inspection, the effluent was slightly cloudier than normal, but the samples taken did pass effluent test that day. The Subcontract Operators keep sludge blankets at 2 to 3 feet as much as possible and waste when needed. This is the only control available to keep solids out of our effluent. Inspection Response Page 3 Jtem #7. The circular clarifier is approximately 10 feet across and 10 feet deep. At the time of the inspection, the sludge depth was 6 feet and the discharge was cloudy. Response: The reason for the sludge blanket depth of 6 feet is that our return sludge flow cannot be increased. We keep it returning to its maximum, but still sometimes the clarifier has slightly more sludge in it than we would like and if we waste too much sludge our MLSS numbers plummet and we don't get maximum removal of BOD, TSS, and other parameters. Mr. Pulley, Kittrell JCC; Facility Maintenance Supervisor and Mr. Matthews, Subcontract ORC Team, also found another contributing factor to our recent return sludge problem. The pipe in the center of the clarifier that pulls the sludge from the bottom and sends it to the aeration basin our digester was eaten up and surely impeded some of the return back to the aeration basin. This contributed to some of the cloudy appearance; but we have been compliant on all samples April 2 - May 02. So the cloudiness is not causing parameter violations. Mr. Pulley has ordered a stainless steel piece of pipe for the clarifier and replaced the corroded pipe, which should have been stainless steel originally. (Any submerged piping in wastewater should be stainless steel). With this new pipe in place our sludge blankets are around 2-3 feet and the effluent is clear. Item #9. Mr. Matthews stated that sludge from this facility is land applied by Granville Farms. Please supply sludge hauling records detailing dates and amounts that were hauled for the period January 2001 through December 2001. Response: Below are the sludge hauling records detailing dates and amounts that were hauled the period requested. Sludge Hauling Record January 01 - December 31, 01 Date of Haul # of Loads Total Gallons (8000 gal/load) 01/09/01 2 16,000 02/02/01 1 8,000 03/09/01 2 16,000 04/20/01 1 8,000 06/06/01 2 16,000 07/22/01 3 24,000 08/29/01 2 16,000 10/21/01 2 16,000 No sludge removals occurred in November or December 2001. Not enough sludge was generated to warrant removal during that period. This period included the two week Winter Break for the students. January 21, 2002 had three loads removed. Inspection Response Page 4 Item # 11. Please detail what type of device is used for reporting daily effluent temperature and how that instrument is calibrated. Be aware that thermometers used for reporting purposes must be calibrated at least annually and a record of that calibration should be kept. Response: We use a NIST approved thermometer for reporting daily effluent temperatures. The actual thermometer is a Thomas thermometer that reads from - 1 to 51 degrees Celsius, ordered from Fisher Scientific. We will check this thermometer against a certified thermometer on a year basis and record in a calibration log. Item # 15.) The facility has applied for Field Parameter Laboratory Certification to conduct Residual Chlorine, Dissolved Oxygen, pH and Temperature measurements. In addition, Mr. Pulley stated that a low level residual chlorine meter is being purchased that can detect to their permit limit of 28 mg/l. Please indicate when that meter is to be purchased. Response: The center has received the Food Parameter Laboratory Certification to conduct the tests. Certification was received June 17, 2002. The new low level residual chlorine meter (PR/2500 spectrum photometer) has been purchased and was received June 17, 2002. Item #16.) The subject facility has been assessed eighteen (18) times for violations of the NPDES Permit since May 1998. The facility entered into Special Order by Consent (SOC) EMC WQ 99-012 on June 19, 2000. That SOC was undertaken by the Permittee to address problems at the wastewater treatment plant but those changes have not been successful in achieving consistent compliance. Most recently, on May 7, 2002, a "Noncompliance Report" was received for a plant upset that discharged 12,150 gallons of partially treated wastewater. According to the report, this was the result of a toilet suck running. This incident indicates that the plant is easily upset and in fact the operator stated that the plant has problems when the students return from holiday breaks. Mr. Pulley stated during the inspection that the facility was recently evaluated to determine what was required to maintain consistent compliance with the subject permit and that he had made recommendations also. He also stated that the City of Henderson's wastewater collection system was three miles away. Please detail the findings of that evaluation along with the feasibility of connection to Henderson's collection system. Please include cost analysis for all options. Upon receipt of this correspondence, please contact Mr. Stafford to set up a Show Cause Meeting at the Raleigh Regional Office to discuss the plant evaluation. Inspection Response Page 5 Response: * The subject plant received considerable upgrades during the year 2000. Upon the completion of the upgrades, the plant was functioning properly and our record indicated long periods of compliance. Although recently, the compliance record was punctuated with sporadic violations, we remain convinced that the current plant is fundamentally sound. The Office of Job Corps is currently conducting a thorough assessment of the plant to determine if the violations are the results of improper operation or because of plant deficiencies. We will present our findings in the upcoming Show Cause meeting scheduled for July 12, 2002. The Office of Job Corps has invested considerable amount of funds in the current plant and we firmly believe that the past history of compliance indicates that the plant has adequate capacity and is capable of meeting the NCDENR requirements. We will evaluate the plant and provide further enhancement where necessary. However, our assessment and findings so far do not support the abandonment of the current plant. We look forward to meeting you and would like to assure you our utmost cooperation. *Denotes response submitted by National Office of Job Corps through PB Dewberry McKissick & McKissick In conclusion, the recommendations/suggestions and information from the Division of Water Quality Central Office are being utilized or reviewed for consideration for use.

Regional Supervisor ' RITTRELL JOB CORPS CENTER P.O. Box 278, Kittrell, N.C. 27544 (252) 438-6161 NON COMPLIANCE REPORT MAY 7, 2002 7:30 P.M. I arrived at KJCC at 5:00 p.m. Upon arrival at the plant, I noticed the flow equalization pump station alarm was on. Upon assessing the situation, there were no blockages. I assumed there must be a toilet hung open in one of the buildings. I called Mr. Pulley's office (Facility Maintenance Supervisor) and got no answer. I then called Mr. Willie McLaughlin Kittrell Job Corps Center (KJCC) Finance Administration Director and spoke to Sandra Parham, Finance & Administration Secretary. She said "She would notify Mr. Pulley". Upon further investigation, I noticed solids leaving the plant and decided to turn off all air in the aeration basins and turn off the arm in the clarifier to prevent more solids from leaving the plant. I then called Ms. Parham back to see if she had contacted Mr. Pulley. She had and he was on his way. I then asked to speak to Mr. McLaughlin and I informed him of the situation. I then decided to turn off all air to the plant; stopping return and aeration at contact chambers. The reason for this was to allow solids to settle. I plan to have contact basins drained May 8, 2002 to get remaining solids out. Mr. McLaughlin came to the plant at 5:25 p.m. and Mr. Pulley followed a few minutes later. Mr. Pulley had been checking dorms to see if he could find the problem. Mr. McLaughlin and Mr. Pulley both toured the plant and again began search for the problem. At 6:10 p.m., Mr. Pulley returned to the plant and had found a toilet stuck running in a construction area that is not used by KJCC employees. He corrected the problem and informed Mr. McLaughlin and myself. At this time I went to the outfall and collected some effluent samples. I tested my self for PH- 6.7, Dissolved Oxygen -8.0, and Chlorine Residual <100. I retained three containers for future testing if needed. There was some evidence of solids at the outfall, but not as bad as I expected. The peak flow I saw was 81 GPM. If this event began at 4:00 p.m. and ended at 6:30 p.m, that is 2.5 hours or 150 minutes x 81 GPM =12,150 gallons of partially treated waste water that left the plant. The plant's (effluent) flow and all basins were all back to normal at 7:30 p.m. on May 7, 2002. Respectfully Submitted James Marshbum, ORC OPERATED FOR THE U.B. DEPARTMENT OF LABOR.

Easley, Governor William G. Ross, Jr., Secretary Gregory J. Thorpe, Ph.D., Acting Director OCT 1 8 2001 Memorandum To: Regional Water Quality Supervisors From: Coleen Sullins Re: Sampling for enforcement purposes and permit modifications ArprA NCDENR NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES We have received several inquiries regarding the validity of effluent samples taken by DWQ staff for enforcement purposes, requirements for incorporating these samples into a permittees DMR reports and different permitting options for facilities with operational problems. This memo will provide guidance and clarification on these matters. Effluent samples taken by DWQ staff and analyzed by a certified laboratory are valid to stand alone for enforcement of daily maximum limits. These samples are not required to be averaged with values from samples that may have been taken for a facility on that day. However, results from samples taken by the permittee may be considered in determining whether to pursue enforcement actions. The inspector's observation with respect to the facilities sampling and laboratory protocols can play an important role in support of enforcement decisions. DWQ samples must be collected as specified in the facility's permit, adhering to protocols for collection, preservation, and transport and be analyzed within specified holding times with chain of custody maintained throughout the process to be valid for enforcement of effluent limits. Correspondingly, it is the position of the agency that samples taken by DWQ staff are not required to be considered by permittees when computing and reporting averages for a month, week or day on a permittees DMR. To do so would require a considerable and unnecessary coordination effort on the part of the Regions and permittees and would lead to many unessential "amended" DMR's being submitted to the agency with data already housed in our files. Further, it is not reasonable to ask Operators in Responsible Charge to certify the accuracy of sample data they had no control over. Samples from facilities with design flows of < 0.03 MGD are routinely required to be taken as "grab" samples. The Director, on a case by case basis, may modify permits for these facilities and require additional, increased and/or different sampling be performed. Given adequate justification, staff may request modification to a facility's permit(s) at any time in the permit cycle to establish a more detailed picture of a facility's effluent quality.

Examples of adequate justification are significant discrepancies between DWQ sampling and permittee sampling for the same time period(s), discrepancies in split sample results and/or solids deposition instream below the facility while the facility shows compliance with its permit limits Typical permit modification requests would include items such as more frequent monitoring of the effluent, (including weekend sampling) additional stream sampling and/or flow proportional composite sampling instead of grab sampling. Recommendations from the regional offices to incorporate such requirements into permits will carry a large amount of influence when supported by adequate justification as described above and detailed explanations as to why the requested modification is warranted. In instances where specific types of operational problems are suspected, staff may seek permit modifications to include permit conditions that address wastewater management. Some of the aspects that a waste management plan would entail are an analysis of treatment and disposal alternatives, a facility assessment and optimization plan, or a biosolid management plan. The plan could also entail an estimate of future flows and a demonstration by the facility to provide the capability for adequate treatment of such flows.
