DANIEL SMITH Director NORTH CAROLINA Environmental Quality Mr. Gavin Arsenault, General Manager Trump National Golf Club Charlotte, LLC 120 Meeting House Square Mooresville, North Carolina 28117 Dear Mr. Arsenault: April 5, 2021 via email Subject: Non -Discharge Permit Inspection TNGC - Permit No.: WQ0015931 Reclaimed Water Irrigation Iredell County Staff of the Mooresville Regional Office (MRO) conducted a compliance inspection on March 5' 2021, which included the pump station, reclaimed water treatment, irrigation sites and a records review. The MRO and Central Office would like to thank the Tri-County Wastewater (TCW) staff, Mr. Brandon Long and Mr. Brian Stephens for their time during the site inspection. The operators have managed to keep the system treatment functional; however, the age of the facility is showing with rust in critical areas of the plant, which if unchecked could lead to functional and potential safety concerns: • The bar screen and grit removal support beams (also supports grating that operators walk on every visit to access and maintain the plant) and aeration fixtures are rusted and need assessment for repair/replacement. Both of these locations are critical to appropriate treatment. Left: Support beams under walkway at head of the plant. Right: Shows corrosion at aeration fixtures. 1:tE Department of Environmental (Wally North Carolina Department of Environmental Quality I Division of Water Resources Mooresville Regional Office 1610 East Center Avenue, Suite 301 I Mooresville, North Carolina 28115 704.663.1699 • Both pumps were replaced at the EQ Basin, but the full supports were rusted out, so the rails were removed and support redesigned for the new pumps; in addition, there is a hole in the wall between the EQ Basin and Digester train that is currently off-line. If this train of the system were utilized a system bypass would occur when Basin volume was approximately 18 inches below the top of the tank. • Most tanks need rehabilitation for rust removal, potential repairs and repainting. Per previous inspections/conversation the operators were in discussion with TNGC for a complete plant replacement so many repairs were postponed; however, the plant replacement was postponed. MRO staff recommends consultation with your engineering and installation contractors to adequately assess repairs vs. replacement and establishment of a timeline for the decided course of action. Additional items to address to maintain overall compliance: • TCW is to establish a timeline for completion of the field lab certification for proposed pH and Total Residual Chlorine, and/or plans for currently certified contractors to assist until certification is completed. There have been legitimate, unforeseen delays in the process; however, Permit Condition IV.2 requires final effluent parameters be analyzed by a certified lab, for all facilities TCW provides this service for, so this item should be a priority.

Drainage feature(s) have developed which are likely leading to runoff and need to be filled with clean soils and/or regraded. Many downed trees, uprooted stumps and underbrush need removal and holes filled. Mulching of irrigation fields is no longer required by permit conditions as it may clog emitters and inhibit dripline assessment. Some permittees have opted to continue using a minimal layer of mulch as preventative measure from animals chewing on the driplines. MRO staff will leave it to the permittee and operator to determine if/when a mulch layer is beneficial, but the mulch application should be minimal and not bury the driplines. • Telemetry at the pump station and the visual alarm at the WWTP were inoperable at the time of inspection. Per email from Mr. Long on March 18th, 2021 the telemetry was repaired and lab data requested for the additional records review was received by MRO staff. The light bulb should be replaced at the WWTP alarm, if not already addressed. Lab data reviewed supported entry in the corresponding NDMRs. Daily WWTP operations logs were reviewed onsite, a couple items were discussed for addition including notation in the comments for all maintenance items (ex: recent pump replacements, dripline repairs, etc.) A separate log is maintained for any contractor residuals cleanouts at the collection system and WWTP. Per records the collection system is likely due for cleanout, as the Grease Traps were last pumped in May 2018 and the Lift Station in July 2019. One lid was sealed in place and needs to be repaired for access. There should be a separate maintenance, visitation log for pump station checks to include date, time of visit, initials of person inspecting, notation of gas volume in generator and pump(s) run-times, etc. Mr. Long stated all logs are kept at the WWTP office; however, when telemetry is not functional, the log should be located at the pump station where TNGC staff will have access for weekend documentation.

The spray system at the driving range continues to utilize another water source for irrigation (well or lake). The driving range acreage is permitted and plumbed for spray irrigation, but has never been utilized for the reclaimed system. Signage would need to be placed at the driving range if this area is to be utilized for reclaimed distribution. Some application fields need clean-up for downed trees, undergrowth and repair of holes created by uprooted trees and newly formed drainage features to prevent ponding and runoff. It just rained the day before, so driplines were not assessed. (See summary and cover letter for comments.)
