PO Box 63 Maggie Valley, NC 28751 SUBJECT: Compliance Inspection Report Dogwood Trails Subdivision NPDES WW Permit No. NC0065986 Haywood County Dear Permittee: The North Carolina Division of Water Resources conducted an inspection of the Dogwood Trails Subdivision on 8/24/2020. This inspection was conducted to verify that the facility is operating in compliance with the conditions and limitations specified in NPDES WW Permit No. NC0065986. Please carefully review the comments noted in the enclosed copy of the inspection report. Additionally, after reviewing historical records, it appears there are discrepancies between the originally permitted AtoC and the permitted hydraulic capacity of the facility. Please provide documentation that shows the currently installed treatment components sizing. This request will be added to the renewed permit, if the additional information is not received before its issuance.

This inspection was conducted to determine whether the facility is being operated and maintained in compliance with NPDES Permit No. NC0065986. Joedavid Hall, ORC, was present and assisted in the inspection. Overall the facility appears to be operated and maintained in compliance. This facility is permitted for 0.02 MGD and is currently in renewal. Please verify the hydraulic capacity of this facility. Historical records indicate it was initially planned for a phased expansion with an initial AtoC approval from the Division for a 0.01 MGD WWTP. A request will be made to verify this during the permit renewal. This is not currently an issue based on average flows; however, as expansion occurs it may begin to exceed the facilities treatment capacity, if only a 0.01 MGD package plant was installed. The ORC indicated new homes were being constructed. All homes gravity feed into the WWTP. Environmental Inc. helps with CS issues when contracted to do so. There were no noted issues with trash or debris in the WWTP at the time of the inspection. The ORC believes each home may have a settling tank. Should facility staff begin to see significant debris entering the WWTP, a bar screen is recommended. Solids are hauled from the facility once a year. Soda ash is used to adjust pH as needed. Mr. Hall does not believe there are any major issues with I&I in the neighborhood based on flows during rain events. The permit is in renewal. When finalized, please ensure a copy is made available to facility staff as there is always the potential for updates to permit requirements. NC0065986 17 (Cont.)

Does the facility analyze process control parameters, for ex: MLSS, MCRT, Settleable Solids, pH, DO, Sludge Judge, and other that are applicable? ORC checks DO and pH.Comment: Permit Yes No NA NE (If the present permit expires in 6 months or less). Has the permittee submitted a new application? Is the facility as described in the permit? # Are there any special conditions for the permit? Is access to the plant site restricted to the general public? Is the inspector granted access to all areas for inspection? Need to verify the hydraulic capacity of the facility. Discrepancies in permitted flow and historical records for phasing. Comment: Flow Measurement - Influent Yes No NA NE # Is flow meter used for reporting? Is flow meter calibrated annually? Is the flow meter operational? (If units are separated) Does the chart recorder match the flow meter? Facility is permitted for 0.02 MGD and only requires instantaneous flow measurement. Flows are determined by volume over time. Comment: Aeration Basins Yes No NA NE Mode of operation Ext. Air Type of aeration system Diffused Is the basin free of dead spots? Are surface aerators and mixers operational? Are the diffusers operational? Is the foam the proper color for the treatment process? Does the foam cover less than 25% of the basin’s surface? Is the DO level acceptable? Is the DO level acceptable?(1.0 to 3.0 mg/l) Page#3 DocuSign Envelope ID: 0ACB22AB-99AA-4575-A1AD-E533360A5714 Permit:NC0065986 Inspection Date:08/24/2020 Owner - Facility: Inspection Type: Dogwood Trails Subdivision Compliance Evaluation Aeration Basins Yes No NA NE ORC attempts to keep DOs within the aeration basin between 1 and 2 mg/L. Only one blower is needed to maintain DOs. Blowers are alternated and run approximately 15 minutes every hour. Comment: Secondary Clarifier Yes No NA NE Is the clarifier free of black and odorous wastewater? Is the site free of excessive buildup of solids in center well of circular clarifier? Are weirs level? Is the site free of weir blockage? Is the site free of evidence of short-circuiting? Is scum removal adequate? Is the site free of excessive floating sludge? Is the drive unit operational? Is the return rate acceptable (low turbulence)? Is the overflow clear of excessive solids/pin floc? Is the sludge blanket level acceptable? (Approximately ¼ of the sidewall depth) ORC reports solids are hauled about once a year. No issues with pass through debris or floating solids. Comment: Disinfection-Tablet Yes No NA NE Are tablet chlorinators operational? Are the tablets the proper size and type? Number of tubes in use?1 Is the level of chlorine residual acceptable? Is the contact chamber free of growth, or sludge buildup? Is there chlorine residual prior to de-chlorination? ORC checks chlorine levels to ensure appropriate disinfection and dechlorination.Comment: De-chlorination Yes No NA NE Type of system ?Tablet Is the feed ratio proportional to chlorine amount (1 to 1)? Is storage appropriate for cylinders? # Is de-chlorination substance stored away from chlorine containers? Are the tablets the proper size and type?

ORC is using one tube for both dechlor and chlorine. Comment: Are tablet de-chlorinators operational? Number of tubes in use?1 Comment: Effluent Sampling Yes No NA NE Is composite sampling flow proportional? Is sample collected below all treatment units? Is proper volume collected? Is the tubing clean? # Is proper temperature set for sample storage (kept at less than or equal to 6.0 degrees Celsius)? Is the facility sampling performed as required by the permit (frequency, sampling type representative)? Grab samples are collected post dechlor since it’s difficult to collect samples from the outfall. Comment: Effluent Pipe Yes No NA NE Is right of way to the outfall properly maintained? Are the receiving water free of foam other than trace amounts and other debris? If effluent (diffuser pipes are required) are they operating properly? Outfall is accessible, but difficult to collect samples from due to location in bank.Comment: Page#5 DocuSign Envelope ID: 0ACB22AB-99AA-4575-A1AD-E533360A5714 Certificate Of Completion Envelope Id: 0ACB22AB99AA4575A1ADE533360A5714 Status: Completed Subject: Please DocuSign: NC0065986_CEI_20200828.docx, NC0065986_CEI_20200828.insp.pdf Source Envelope: Document Pages: 7 Signatures: 3 Envelope Originator: Certificate Pages: 2 Initials: 0 Mikal Willmer AutoNav: Enabled EnvelopeId Stamping: Enabled Time Zone: (UTC-05:00) Eastern Time (US & Canada) 217 W.
