Signature of report preparer: Signature of APS regional supervisor: Date: V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS July 18, 2018 – ARO received the complete (cover letter requesting that Attachment B of WQ0024694 be updated to reflect Bright’s Creek Holdings as the owner of the golf course and spray irrigation fields) application via e -mail from Alice Wessner. An Amended And Restated Effluent Easement and Irrigation Agreement dated March 26, 2007 was submitted with the renewal application. The easement is with Bright’s Creek Holdings, LLC and the current property records show Alianza Trinity Development Group as the golf course owner. Water supply wells (WSW) are located within the Compliance Boundary according to the 2007 facility site map. The new owner will need to request a change in the Compliance Boundary to exclude the WSW’s. The original permit dated January 24, 2005 to Heater Utilities, does not specifically show Heater Utilities as the owner of the irrigation sites. It does state ”for the construction and operation of a 120,000 GPD wastewater treatment and reclaimed water utilization system…” The permit dated March 31, 2006 does include the 132.8 acres of spray irrigation area in the permit description. The permit dated May 3, 2012 was for an ownership change from Heater Utilities, Inc. to Aqua North Carolina. The May 3, 2012 first showed Aqua North Carolina, Inc. as the owner of the irrigation sites.

Rickie Daniels assisted with the inspection. Mr. Daniels indicated that he uses dissolved oxygen, settleability and pH readings for WWTP process controls as well as the effluent pH, chlorine and turbidity readings. pH: 4.56 in the Aeration basin – measured with ARO field meter Dissolved Oxygen: 5.4 mg/l – measured with the ARO field meter The turbidity meter was not calibrated in 2017. The current permit does not require calibration but it is recommended. Turbidity read 1.39 NTU’s. The effluent flow meter (ISCO Model 4210) was calibrated on 12/13/17 by Billy Fisher with Clearwater, Inc. The effluent sampler thermometer read 3 degrees celsius and was calibrated by Tony Gragg (Water Tech) on 4/17/17. The sampler is set to collect 100 mls of sample and is set for time composite rather than flow proportional. The automatically activated generator needs a new control panel according to the ORC. In the interim, a portable generator has been installed. Please recall permit condition III.10. which states, “if a generator is employed as an alternate power supply, it shall be tested weekly by interrupting the primary power source”. The tertiary filter is backwashed once per week. This facility services a vacation/second home community and as a result the system is under loaded. The lack of influent makes optimum WWTP operation difficult. Activated sludge is very light in color and solids removal has not been needed so far. Even though the system is under utilized and sludge has not been pumped from the facility, it is recommended that a sludge judge be kept on site to periodically check the solids levels in the clarifier. The sludge return junction box needs to be evaluated for a seal/cover; sludge was splashing out onto the ground. A copy of the permit should be kept at the facility. The Influent Lift Station is fenced and contains emergency contact information. A standby gas powered generator is on site and is automatically activated weekly. A spare pump is on site. Log books appeared to be complete. Irrigation was not occurring at the time of inspection. The following operation /maintenance items were not compliant: 1. Erosion was observed on the northeast slope of the 5-day upset pond. 2.The Operation and Maintenance Plan was not available. The following Performance Standard was not compliant: A permit (Attachment B)/file review shows that Aqua North Carolina, Inc. is the owner of the irrigation fields (132.8 acres) for Bright’s Creek Golf Club. The Polk County property records indicate Alianza Trinity Development Group as the owner of the golf course (irrigation fields). This is a violation of permit condition VI. 5. (Change of Ownership needed). A permit/file review shows that water supply wells (WSW) labeled U, V and W as shown on the 2007 as-built map appear to be located within the Compliance Boundary (CB). This is a violation of permit condition II.10.

A portable generator is on site. The turbidity meter has not been calibrated in the last 12 months; calibration is not required in the current permit. The turbidity reading was 1.39 NTU's. Effluent not meeting the reclaimed turbidity standard of 10 NTU's is automatically diverted to the 5-day upset pond where it can then be rerouted back to the head of the treatment plant. Effluent not meeting the fecal coliform standard would not automatically be routed to the 5-day pond as the sample result is not instantaneous. The receiver site is a golf course so public access is not restricted, however, irrigation is not usually occurring when golfing is occurring. The golf course is currently closed; there was no access to the clubhouse to determine if a reclaimed notification sign is located there.
