Director NORTH CAROLINA Environmental Quality September 21, 2023 CERTIFIED MAIL No. 7019 1120 0001 5505 1886 RETURN RECEIPT REQUESTED George Gudgeon — Senior Vice President MHC TT, L.P. 2 North Riverside Plaza — Suite 800 Chicago, Illinois 60606 SUBJECT: Notice of Violation (NOV-2023-PC-0487) Compliance Evaluation Inspection Forest Lake Preserve WWTP Permit No. WQ0004972 Davie County Dear Mr. Gudgeon: On September 7, 2023, Division of Water Resources staff Caitlin Caudle and Kristen Potwora conducted a routine compliance inspection of the Forest Lakes WWTP facility. Amanda Grenier, Wendy Champagne, and Sam Perry of Greener EHS Solutions were present during the entire inspection. A review of available records, treatment, storage, and irrigation facilities, monitoring wells, and lift stations was completed. This review reflected non-compliance with the subject permit. The following violations were noted- 1 . At the time of inspection, Staff recorded the GPS coordinates of each monitoring well (MW). When recording the location of MW-4, standing water and directional flow was discovered upslope of the MW. Staff tracked the directional flow to the base of a pine tree approximately 120ft upslope. Greener EHS Solutions staff investigated further and found a broken supply line intended for the original park expansion. Mrs. Grenier sent photos on September 8, 2023, showing the broken pipe and the repair. See attached map and photos for reference. Per Permit Condition V.1, the Permittee shall perform inspections and maintenance to ensure proper operation of the wastewater treatment and irrigation facilities. The broken pipe as described above resulted in a discharge of effluent to land surface and improper operation of the irrigation facilities. Moving forward, routine inspections should be conducted of all treatment and irrigation facilities; especially when irrigation is actively occurring. North Carolina Department of Environmental Quality I Division of Water Resources Winston-Salem Regional Office 1 450 W. Hanes Mill Rd, Suite 300 I Winston-Salem, North Carolina 27105 NoanicaaouNn oep.m.m or em�nmen� Qualm 336.776.9800 2. Per Permit Condition 111.3, the Permittee shall designate an ORC and BUORC for each classification of the subject non -discharge facilities. The Forest Lakes WWTP and irrigation facilities have a classification of WW-2 and SI. To date, operator designations have only been made for the SI classification. Designate an ORC and one or more BUORC for the WW-2 classification as soon as possible. The following items of concern was noted: A. On November 3, 2022, the Winston Salem Regional Office was notified that a blower at the treatment plant was not operational. At the time of inspection, both blowers were operational and all diffusers, air plates, and air supply lines in the treatment plant were replaced. However, staff noted that the elbow on an airline in the aeration basin was broken and leaking. Per Permit Condition V.1, the Permittee shall perform inspections and maintenance to ensure proper operation of the wastewater treatment and irrigation facilities. Please repair this airline as soon as possible. B. The most recent permit description lists a hypochlorinator as the chlorination method. The hypochlorinator system has not been operational since at least 2018. Chlorine tablets are currently being used. Per Permit Condition V.1, the Permittee shall perform inspections and maintenance to ensure proper operation of the wastewater treatment and irrigation facilities. Please determine if the hypochlorinator system is still operational and make necessary repairs. A permit modification can be requested if tablet chlorination is a more appropriate disinfection method at this time. C. Per Permit Condition 111.14, a gauge to monitor waste levels shall have readily visible permanent markings, at inch or tenth of a foot increments, indicating the following elevations: maximum liquid level at the top of the temporary liquid storage volume; minimum liquid level at the bottom of the temporary liquid storage volume and the lowest point on top of the dam. The current staff gauge only has foot markings. A new gauge should be installed and certified as soon as possible. D. The well plates installed on all monitoring wells do not include all minimum information as described in 15A NCAC 02C .0108(p). Two well plates do not match the Division approved labeling of the wells. Per Permit Condition 11.3, groundwater monitoring wells shall be constructed in accordance with 15A NCAC 02C .0108 (Standards of Construction for Wells other than Water Supply). Efforts should be made to locate the original well plates or well construction permits to install correct well plates. E. A well casing is visible downslope of the storage pond. A well abandonment form was found in the records of the previous operator. The GPS coordinates on the form do not correspond with the well downslope of the storage pond. Further investigation is needed to determine the original purpose of this well and if it has been properly abandoned. If the well has not been properly abandoned, it should be done as soon as possible.

The collection system serving the Forest Lakes WWTP is a deemed collection system. The deemed collection system rules can be found at 15A NCAC 02T .0403(a) and are included as an attachment to this correspondence. Other observations: • Samples were collected at the time of inspection at the pine tree described in Item 1 above. Samples were collected the next day from the irrigation wet well. Results have not been received to date. • The malfunctioning blower has been repaired and the plant is now aerated 24/7. • The floating solids in the EQ basin have been removed and the air plates were repaired. • The forcemain entering the treatment plant was repiped to include the forcemain from the new area of the resort. All influent is now passing through the bar screen. As noted in the inspection report associated with the June 29, 2022 inspection, the forcemain for the new areas of the resort had been previously piped directly into the EQ basin, bypassing the bar screen. • Mr. Perry has installed a chlorine tube at the end of the clarifier weir for effluent to contact the tablets before entering the contact chamber. • The clarifier weir and trough were clear of debris. • An updated site map was not available to staff. • Mrs. Grenier estimated 400 camping spots in the resort after the most recent expansion. • Mrs. Grenier stated that another solids cleanout of the storage pond is planned. Irrigation is limited by the solids level in the storage pond. • To date, the irrigation system has not been calibrated. This must be completed by 10/31/2027. • Based on monthly sampling, the biology of the WWTP has improved with increased aeration. • The clarifier was completely emptied and solids removed in August. • Based on observations of the WWTP, solids handling has improved in the WWTP. Solids have not been removed from the sludge holding tank since Greener EHS Solutions began operating the system. • All nine lift stations were reviewed. All control panels have a receptacle to connect back up power, and audible or visual alarms. • A handheld DO meter and settleometer are used by operators. • Per the June 29, 2022 inspection report, improper chlorine tablets were being used and proper disinfection was not beinc achieved. Proper chlorine tablets are now being used and adequate disinfection is being achieved. • The previous operator calibrated the flow meter as a V-notch weir, causing the flow meter calibration to be incorrect and reported flows to be incorrect. Greener EHS Solutions calibrated the flow meter as a rectangular -notch weir, resulting in reported flows to increase significantly. • Freeboard was 3.2ft at the time of inspection. • A thick duckweed mat covers the storage pond. • A flow meter was installed on the forcemain to the irrigation fields. • Two geoborings were found at the edge of the irrigation field. • Nitrate in MW3 exceeded the groundwater limit of 10 mg/L and was consistently elevated since at least November 2020. See the below table. Further action may be needed if exceedances continue.
