Expedited permits are generally simple 100% domestics (e.g., schools, mobile home parks, etc.) that can be administratively renewed with minor changes but can include facilities with more complex issues (Special Conditions, 303(d) listed water, toxicity testing, instream monitoring, compliance concerns). Basic Information for Expedited Permit Renewals Permit Writer/Date Charles H. Weaver 12/7/2022 Permit Number NC0023124 Facility Name GGCC WWTP Basin Name/Sub-basin number 03-08-30 Receiving Stream Linville River Stream Classification in Permit C-Trout Does permit need Daily Max NH3 limits? No — already present. Limits in the permit have been in place since 1993 and are more stringent than the limits required for protection from ammonia toxicity instream. Existing NH3 limits will remain to prevent concerns about backsliding (tox-based limits would be looser). Does permit need TRC limits/language? No — already present Does permit have toxicity testing? No Does permit have Special Conditions? No Does permit have instream monitoring? No Is the stream impaired (on 303(d) list)? No Any obvious compliance concerns? Five enforcements in this permit cycle, and 5 NOVs in the same period. No effluent violations since 2020. Any permit modifications since last permit? None. New expiration date 1/31/2027 Changes to Draft Permit > Updated eDMR requirements ➢ Added monitoring for turbidity to determine compliance with 15A NCAC 02B.0211 (21). > Added monitoring for dissolved oxygen to determine compliance with 15A NCAC 02B.0211 (6). > Added instream monitoring for temperature as per 15A NCAC 02B.0211 (18). Comments on draft permit > Catawba River Foundation requested limits for dissolved oxygen, turbidity, and instream temperature. They also requested sampling for e coli and instream monitoring for fecal coliform. They also requested a compliance schedule to resolve issues from past inspection reports. The comment letter was dated 11/28/2022, after the 30-day comment window had closed. This page has been printed on scrap paper to save money and reduce our program's environmental impact.

Regarding the CRF comments: > Monitoring for DO, turbidity, and instream temperature will be evaluated at the next permit renewal to determine if limits are necessary. > NPDES management determined that discharges from 100% domestic WWTPs are not a "heated liquid" as described in the rule, thus negating the requirement for an instream temperature limit. ➢ The Division only requires instream fecal monitoring if the receiving stream is impaired for fecal coliform. ➢ The Division does not have a policy for monitoring e coli at present. > The inspection findings from 2016 and 2021 will be handled by the ARO with enforcements as necessary. There have been no effluent limit violations since 2020, and the ARO will continue to press for repairs/upgrades at the facility.

Our organization represents over 6,000 active members who rely on the watershed for drinking water, recreation, and electricity. The Linville River is a major tributary to Lake James and is a designated Class C trout water. In addition, this facility discharges upstream of the Linville Gorge Wilderness, which features a designated NC Natural and Scenic River section of the Linville River. We appreciate the opportunity to comment on the Grandfather Golf and Country Club WWTP NPDES permit (NC0023124) and make the following recommendations: • Limit discharge turbidity The facility discharges into a designated trout water. Discharge should be limited to ensure stream turbidity does not exceed 10 NTUs. • Limit discharge dissolved oxygen The facility discharges into a designated trout water. Discharge should be limited to ensure stream dissolved oxygen is not less than 6 mg/L. • Limit discharge temperature at 20 degrees C The facility discharges into a designated trout water. The draft permit does not include a temperature limit. This still appears to violate 15A NCAC 02B .0211(18) "... the temperature for trout waters shall not be increased by more than 0.5 degrees C due to the discharge of heated liquids, but in no case to exceed 20 degrees C;." • Monitor up and downstream fecal coliform weekly The 2016 inspection noted "Overall this system is aged and has a design that is difficult to evaluate thoroughly since it is mostly a covered system. At a glance neither the WWTP nor the river indicated that the WWTP is leaking, however given its age an evaluation of the structural integrity of the system should be considered. The adjacent channel could be sampled upstream and downstream of the WWTP for bacteria as an initial indicator." Since then, multiple violations have been attributed to heavy holiday use and inflow & infiltration. We are unaware of planned or completed major system upgrades.

Last year DWR proposed updating the standard and the Environmental Management Commission approved the measure. Linville River users should not have to wait another 5+ years for a more accurate measure of fecal contamination. • Establish a compliance schedule to resolve all issues from inspection reports Since the last permit was issued, 11 violations have been reported; 3 of which led to formal enforcement action. The 2016 and 2021 inspections noted several major issues that need to be resolved before a new permit is issued. These include: ■ Repair the substantial leak that appears to be coming from the influent pipe for the UV disinfection. ■ Install proper pumps and a splitter box to ensure a functional EQ basin. ■ Rectify issues with fourth clarifier to ensure its proper function and performance. ■ Confirmation of a functioning bar screen. ■ Confirmation of standby power. ■ Operation of permit required tertiary filter.
