The purpose of the inspection was to verify that the facility is operating in compliance with the conditions and limitations specified within Permit NC0007064. Present during the inspection were Drew Petrusic and Eric Caison with the system as well as William Wells and Joseph Babson (both BORCs) also with the system but only present while at the Support Facilities Wastewater Treatment Plant (i.e., WWTP) as well as Bryan Lievre with NCDEQ. The permit provides for the following outfalls: 1. Outfall 001, which is generally plant cooling water but also includes flow from Internal Outfalls 003, 005, 006, 010, 011 and 012. For Outfall 001, from April 1, 2022 through May 30, 2024, the maximum daily flows were equal to the permit limits for each period and an exceedance was not reported. During the same period, the reported pH in Outfall 001 ranged from 7.1 to 8.1 with an average of 7.82 which is also within the established permit limits. No detectable levels of total residual chlorine were reported at this location during this period. Total Beta radioactivity sampling results were 332 pCi/L on 11/16/2023, 101 pCi/L on 1/18/2024, 222 pCi/L on 3/25/24 and 258 pCi/L on 5/22/24. Thermal Reports from 11/2/2022, 1/12/23, 11/08/2023 and 3/14/2024 were reviewed and found to be in general conformance with permitted limits as described in permit condition A.(1). 2. Outfall 003 has three Radwaste Treatment Systems, although the waste from all is intermittent and eventually flows from the same discharge line. Sampling conducted on November 12, 2022 and November 26, 2023 indicates that results for this outfall are in compliance with established permit limits and had an average flow of 0.023 mgd during the two sampling events; 3. Outfall 005 is a Drain Holding Facility (DHF) which has replaced a legacy Drain Stabilization Pond. The primary input into the pond is surface water runoff and effluent drains into Outfall 011. The 4.2 acre, approximately 4 million gallon pond had been placed into operation following the previous inspection performed on 5/26/2022. Sampling conducted from April 2022 through April 2024 indicates that the system had four discharge events over this period and that results for this outfall are in compliance with established permit limits. It should be noted that holes had been detected in one of the two liners, so the pond had been drained and taken back out of service for anticipated repairs prior to the recent inspection. 4. Outfall 006 is for the discharge of treated metal cleaning wastes and has not been utilized during this permit cycle (i.e., since prior to April 6, 2018); 5. Outfall 010 is for the Support Facilities Wastewater Treatment Facility (WWTP). This is a 0.150 million gallon per day (mgd) system which includes 12 lift stations (only four of which pump directly to the WWTF), three fine screens, four sequencing batch reactors, an effluent flow meter, two disc filters and two UV disinfection units. The system also has two aerated sludge basins and a sludge thickening system. All parameters during the period of 1/2022 through 5/2024 were all within permitted levels, the average daily flow for Outfall 010 was 0.008 mgd, TSS averaged 3.7 mg/L and BOD5 had an average of less than 5 mg/L. 6. Outfall 011 is for a Storm Drain Stabilization Pond (SDSP). There are eight intermittent and routine sources which are routed to this outfall. Potential discharges include those from an Auxiliary Boiler System, HVAC Cooling Towers, aDemineralized Water System, a Standby Liquid Control Test Tank, Turbine Building Closed Cooling Water, Diesel Generator Cooling Water System, Maintenance Activities and an Independent Spent Fuel Storage Installation (ISFI). Outfall 005 can receive the same inputs described above when the SDSF is not available and Outfall 012 can also be routed to the Storm Drain Stabilization Facility. Discharge from Outfall 011 is into the intake canal. From 1/2022 through 5/2024 all parameters were within permitted levels and the flow averaged 0.4613 mgd, TSS had an average concentration of 3.33 mg/L and oil and grease was typically non -detectable (i.e., less than 5 mg/L) but had a maximum daily concentration of 5.56 mg/L. 7. Outfall 012 is for discharge of the Groundwater Well Extraction System. This system recovers groundwater with tritium levels of concern from the area of the former Storm Drain Stabilization Pond. The outfall is typically directed to the intake canal via Outfall 011, but can be directed to Outfall 005. Although there was no flow reported in Outfall 012 during the period of 1/2022 through 5/2024, the groundwater extraction system reportedly operated and flows were incorporated into Outfall 011.

Owner - Facility: Brunswick Steam Electric Plant Inspection Type: Compliance Evaluation Yes No NA NE ■ ❑ ❑ ❑ ❑ ■ ❑ ❑ Comment: There are two laqoons which are associated with Outfalls 005 and 011. Both laqoons are equipped with various types of black balls of various design, intended to inhibit evaporation and prevent algal growth. The lagoon for Outfall 005 is called the Drain Holding Facility (DHF) which is a low volume waste pond which has replaced the Storm Drain Stabilization Pond. The lagoon has a capacity of approximately 4 million gallons, was constructed with a double liner and discharges into Outfall 011. The sensors between the liners had detected a leak and so the lagoon was drained and down for impending repairs during the recent site visit. The lagoon associated with Outfall 011 is called the Storm Drain Stabilization Facility Pond (SDSF) and is approximately 6 millions gallons and discharges on a weekly basis during normal operation to the intake canal. No exceedances of permit limits were documented from 1/1/2022 through 5/30/2024 for Outfalls 005 nor 011.
