The facility has several other outfall locations tributary to the 001 outfall into the Atlantic Ocean. Two of these other outfalls are for domestic wastewater treatment. Equipment descriptions located in the previous permit are sufficient. Proposed flow: 1,900 MGD — with permit provision for periods of increased flowrates if power demand or ambient water conditions require the increase. Current permitted flow: 1,900 MGD — with permit provision for periods of increased flowrates if power demand or ambient water conditions require the increase. The Wilmington Regional Office agrees with the suggestion regarding the reformat of the flow rates table A. (1) Effluent Limitations and Monitoring Requirements [0011 included in the Duke Progress Energy renewal application cover letter received on May 26, 2016. A complete list of possible seasonal flow conditions would be clearer. The Wilmington Regional Office understands that Duke Energy Progress intends to construct a larger single wastewater treatment facility that will treat wastewaters currently discharged from Outfalls 004 and 010 at the BSEP site. These 2 two outfalls currently use smaller package plants for treatment of the domestic wastewater generated at the site. During refueling outages when on-site staffing significantly increases; the package plants have experienced upset conditions. To eliminate the possibility of these package plant upsets, Duke Energy Progress has obtained Pump and Haul permits to allow them to transfer excess wastewater to Brunswick County for final disposal. The planned new domestic wastewater treatment facility will allow BSEP to operate through refueling outages and other periods of high staffing without process upset. 3.

NC0007064 111 121 16/04/26 1 17 18 i c 1, Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) Compliance inspection for this site was conducted on April 26, 2016, the facility is clean and well maintained and is compliant with permit requirements. This site is a 1,900 MGD facility with the bulk of the water being once -through cooling water used for the turbine condenser system. Several other outfalls are located throughout the site and all are recombined prior to discharge in the Altantic Ocean. Outfall 001 -is the outfall into the Atlanic Ocean which is cooling water and other combined outfalls. Cooling water is withdrawn from the lower Cape Fear River, through a diversion fence to remove larger debris into an intake canal. The cooling water pumps that provide flow to the power blocks are equipped with 50 rotating debris screens, these screens remove smaller debris and aquatic organisms, which are returned to the river estuary via a flume. Biological monitoring is performed monthly on the number and species being returned, this data is then compiled into an annual bio -monitoring report. Typically 3 of 4 cooling water pumps are in service for each power generation unit, flow rates are also contriolled by cooling water valve position and by the number of water boxes in service. Flow rates and other information is provided to the environmental staff each morning by a "Screen Wash Report". Cooling water flow rates are highest in the warmer summer months reaching up to 2,335 cfs (1,500 MGD) and returning to 1844 cfs (1,192 MGD) in the winter. Outfall 003- Rad -Waste Treatment Plant: DMR reports indicate compliant operation. Outfall 004- Operations Area Wastewater Treatment Plant: A package plant for domestic wastewater treatment inside the power generation areas, DMR's indicate compliant operation. Outfall 005- Old Stabilization Pond: a 39 acre unlined basin that previously received stormwater and misc. waters from several areas. This pond currently only receives rainfall that falls within the pond area and the level is monitored weekly, when needed, the accumulated water is released to the cooling water intake canal for disposal. Outfall 006- Metal Cleaning Wastewaters: Not in use at this time. Outfall 010- Support Services Area Wastewater: This treatment system was inspected and evaluated in the questions section of this report. Outfall 011- Storm Drain Stabilization Facility: this lined pond receives site stormwaters and other misc. waters from the site with water being released into the cooling water intake canal for disposal. This facility also receives recovered groundwater from 92 air -driven well pumps at total flow of approximately 40 gpm, that surround the formerly used 39 acre pond associated with Outfall 005. These groundwater recovery wells/pumps are in place to contain a tritium contamination from the unlined pond. DMR's indicate compliant discharges from this outfall. Outfall 012- Direct recovered groundwater discharge: this is currently unused as recovered groundwater is first processed through the Storm Drain Stabilization Facility and becomes a constituent of Outfall 011. A brief inspection of the field parameter testing equipment and documentation was performed during this inspection. Each operator maintains their own individual logbook documenting operations activities, sampling events and meter calibrations. A logbook also maintains records of TRC calibration curves for each operator. New calibration curves are created based on the expiration of the chlorine standards. New TRC curves were performed by each operator in February and March of 2016. Temperature probe compensation was checked on DO and pH meters on 04/25/2016.
