DANIEL SMITH Director NORTH CAROLINA Environmental Quality July 19, 2021 CERTIFIED MAIL 7018 1130 0000 1612 5419 RETURN RECEIPT REQUESTED Mr. Walter B. Craven, Jr. Lakeview MHP LLC 420 Marion Dr. #31 Wilmington, NC 28412 SUBJECT: Notice of Violation (NOV-2021-PC-0346) Lakeview MHP WWTP Permit No. NC0051713 Forsyth County Dear Mr. Craven: On July 9, 2021, staff of the North Carolina Division of Water Resources Winston-Salem Regional Office (Division) performed an announced routine compliance inspection of the subject Wastewater Treatment Plant (WWTP). The inspection was conducted by Division staff members Patrick Mitchell and Jordan Burbage from the Winston-Salem Regional Office. A separate in -office file review of the self -monitoring reports was also conducted for the reporting period of January 2019 through April 2021. The inspection found the subject facility to be noncompliant with NPDES Permit No. NC0051713. Therefore, this inspection report is being sent as a Notice of Violation. The violations listed below require your attention and action. 1. At the time of the inspection there were no records for solids removal from the system (i.e., no septic tank cleanouts and no WWTP sludge cleanouts). Permit Part II.C.6. requires that solids, sludge, etc. shall be removed and disposed of in accordance with NCGS 143-215.1. Permit Part II.D.6. requires that records of sewage sludge shall be retained for a period of at least five years. Failure to remove solids from the system and maintain records of removal is a violation of Permit No. NC0051713. This is a repeat item that was also included in a Notice of Violation issued in July 2018 following the most recent onsite compliance inspection. Please forward copies of all solids removal records for the period of January 2019 through present to this office to my attention. To avoid future non-compliance, please maintain records of solids removal events (e.g. hauling records, removal logs, etc.) onsite and have them available for review during future compliance inspections as required. 2. At the time of the inspection, four of the five diffusers serving the system's aeration basin were found to not be operating properly. Permit Part II.C.2. requires that the system shall be properly operated and maintained at all times. Failure to properly operate and maintain North Carolina Department of Environmental Quality I Division of Water Resources Winston-Salem Regional Office 1450 West Hanes Mill Road, Suite 3001 Winston-Salem, North Carolina 27105 336.776.9800 DocuSign Envelope ID: E7C0C368-00BD-4136-99B6-EE15C407B479 the diffusers on the aeration basin is a violation of Permit No. NC0051713. It should be noted that onsite representatives indicated diffusers are most likely clogged. Solids and trash were observed to be present in the aeration basin. Failure to adequately remove solids from the septic tanks serving the system is likely contributing to this violation. Please take necessary actions for cleaning, repairing, or replacing diffusers as soon as possible. Adequate removal of solids and trash from the system may help ensure proper operation of diffusers and prevent future malfunctioning. 3. At the time of the inspection the skimmer serving the clarifier was not functional. Again, Permit Part II.C.2. requires that the system shall be properly operated and maintained at all times. Failure to properly maintain the skimmer serving the clarifier is a violation of Permit No. NC0051713. It should be noted that solids were observed bulking in the clarifier at the time of inspection. Also, solids and trash were observed in the skimmer trough. Trash should primarily be removed during primary treatment within the septic tanks serving the system. If solids removal is adequate from septic tanks, minimal trash should be present in the clarifier. Please repair the clarifier skimmer as soon as possible. Again, adequate removal of solids and trash from the system may help ensure proper operation and prevent future malfunctioning. 4. The discharge monitoring reports (DMR) for the subject review period reported multiple effluent limit exceedance violations for Ammonia, Fecal Coliform, TSS, and BOD. These violations resulted in a total of five Notices of Violations, two Notice of Deficiencies and one Enforcement issued during the review period. It should be noted that the April 2021 DMR also reported effluent limit violations for Ammonia and Fecal Coliform, which has not been addressed by this office yet. These exceedances are chronic repeat violations of Permit No. NC0051713, Part I.A.1. These effluent limit exceedance violations could be a result of the operations and maintenance violations listed above. Please take actions necessary to allow proper operation, maintenance and repair of the subject system to help ensure effluent limits are met in the future. In addition, the following item of concern also warrants your attention and action: At the time of inspection, a water hose that was connected to a potable water faucet was found to continuously be leaking potable water into the chlorine contact chamber just prior to the effluent sampling location. Permit Part II.A. and Part II.D.1. both require that the effluent samples collected, and the measurements taken shall be representative. Sampling effluent that is diluted with potable water prior to a sampling point is not representative of effluent produced from the WWTP. Please remove the water hose that is discharging potable water when cleaning operations are not being conducted. A Notice of Violation is being issued for the above listed violations of NPDES Permit No. NC0051713. Pursuant to G.S. 143-215.6A, a civil penalty of not more than twenty-five thousand dollars ($25,000.00) as well as criminal penalties may be assessed against any person who violates or fails to act in accordance with the terms, conditions, or requirements of any permit issued Page 2of3 DocuSign Envelope ID: E7C0C368-00BD-4136-99B6-EE15C407B479 pursuant to G.S. 143-215.1. Please provide a written response to this office within thirty (30) days of receipt of this Notice regarding your plans or measures to be taken to address these violations. Please include any information requested above with your response. Remedial actions should have already been taken to correct these problems and prevent future occurrences. The Division appreciates your immediate attention and action. Please be aware that failure to properly address the items listed above may result in further enforcement actions. Please refer to the enclosed compliance inspection report form for additional observations and comments. If you believe the violations are of a continuing nature, not related to operation and/or maintenance problems, and you anticipate remedial construction activities, then you may wish to consider applying for a Special Order by Consent. As a reminder, Permit Part II.E.6., requires that the Permittee or Permittee's representative shall verbally notify the Regional Office as soon as possible, not to exceed 24 hours, from first knowledge of any non-compliance at the facility including limit violations, bypasses of, or failure of a treatment unit. A written report may be required within 5 days if directed by Division staff. In addition, Regional Office notification shall be given for anticipated noncompliance or potential problems due to planned maintenance activities, repairs, taking units off-line, etc. If you have any questions regarding this Notice, please contact Patrick Mitchell or me at the letterhead address or phone number, or by email at patrick.mitchell@ncdenr.gov.

Mr. Randy Bell (ORC) accompanied staff on the inspection. An in -office review of self -monitoring reporting data (DMRs) for the period of January 2019 through April 2021 was also conducted as part of this inspection. The inspection found the subject facility to be noncompliant with the permit. Below is a summary of observations & violations noted during this inspection. Follow up inspection is needed to ensure corrective actions are taken in a timely manner. 1. During the subject review period for self -monitoring reporting data there have been five NOVs issued, two NODs issued, one Enforcement and there are violations reported in the April 2021 DMR that need to be addressed. Ammonia, TSS, BOD, and Fecal Coliform exceedances have occurred during this period. 2. There were no records available at the time of the inspection for solids removal from the system (none for the septic tanks or WWTP sludge). Onsite representatives indicated the septic tank pumping service provider is being switched in an effort to obtain solids removal records. Reportedly Transou's Septic Tank Service will begin routinely pumping out the septic tanks serving this system along with any sludge accumulated in the WWTP, and providing records to the ORC. The previous septic tank pumping service was reportedly pumping out tanks once every six months. If this is the case, it appears to be grossly inadequate to prevent solids and trash from entering the WWTP (see items below). There is no bar screen present on the WWTP due to the septic tanks being present for solids and trash removal. 3. There are reportedly five septic tanks serving this system which provide primary treatment for the system (solids removal). However, there is no records of any solids being removed from the system (septic tanks or WWTP). It should be noted that this violation was included in an NOV issued in July 2018. Requested solids removal records be obtained and made available for future inspections. 4. The septic tanks serving this system reportedly do not have effluent filters present and it is unknown if they have sanitary T's present in the tanks either. The exact locations of the septic tanks are unknown. Division staff was able to locate four concrete risers located inside the MHP that may be the location of four of the five septic tanks. Request that the Permittee provide a site map showing the locations of the five septic tanks. 5. The aeration basin serving the system was found to be in need of repair at the time of the inspection. Only one of the five diffusers was operating properly at the time. Diffusers #1 appeared to not be working at all. Diffusers #2, #4 and #5 were very weak. Diffuser #3 was doing most of the work at the time of inspection. There was a lot of solids including trash present in the WWTP at the time of inspection. Onsite representatives indicated that the diffusers are clogged. Diffusers that were either not working or barely working need to be cleaned, repaired, or replaced as soon as possible. Reportedly DO was running —2.8 mg/L and settleability —360 mL (jar method) at the time of inspection. Note: these measurements were not conducted during the inspection. 6. The skimmer serving the clarifier was not working at the time of the inspection. Needs to be repaired or replaced as soon as possible. 7. The clarifier appeared to have a lot of solids present with some sludge bulking to the top of the clarifier. A sludge judge was not available for sludge depth measurement at time of the inspection. Request that a sludge judge be present for measurement during the follow up inspection. Trash was also found to be present in the clarifier. Algal growth was present on weirs and a minor amount of solids and what might be fungal growth was observed to be in the trough. Weirs need to be cleaned Page# 2 DocuSign Envelope ID: E7C0C368-00BD-4136-99B6-EE15C407B479 Permit: NC0051713 Inspection Date: 07/09/2021 Owner - Facility: Lakeview Mobile Home Park WWTP Inspection Type: Compliance Evaluation soon. 8. It appears that mismanagement/insufficient removal of solids is contributing to the issues noted at the WWTP. The issues noted during the inspection are contributing to the chronic effluent limit exceedances that are reported. 9. At the time of the inspection a garden hose connected to the potable water faucet was found to be leaking a continuous stream of potable water into the chlorine contact chamber, just prior to the effluent sampling point. Effluent was found to be clear and odorless with no foam or solids present. Potable water should be turned off and not left running into the effluent. Sampling effluent that has been diluted with potable water is not representative of effluent produced from the subject system. Request water hose not be left running into the chlorination chamber. OTHER NOTES: • Water use meter is now being used to calculate average daily flows with weekly meter readings. Daily flows using water use data is averaging around 1,000 GPD. • Checked lab reports for April 2021 DMR. Lab report supports DMR data and chain of custodies present. • Upstream and downstream sample stations were reviewed. Upstream location had very little flow. Downstream sample is being collected from Cuddybum Branch just below confluence with the UT that receives effluent discharge. Stream appears to be healthy with no algal growth, no fungal growth, fish present, no odors or foam observed. *FOLLOW-UP INSPECTION NEEDED Page# 3 DocuSign Envelope ID: E7C0C368-00BD-4136-99B6-EE15C407B479 Permit: NC0051713 Inspection Date: 07/09/2021 Owner - Facility: Lakeview Mobile Home Park WWTP Inspection Type: Compliance Evaluation Permit Yes No NA NE (If the present permit expires in 6 months or less).
