Page# 2 Permit: NC0024392 Inspection Date: 03/03/2021 Owner - Facility: McGuire Nuclear Power Plant Inspection Type: Compliance Evaluation Permit (If the present permit expires in 6 months or less). Has the permittee submitted a new application? Is the facility as described in the permit? # Are there any special conditions for the permit? Is access to the plant site restricted to the general public? Is the inspector granted access to all areas for inspection? Yes No NA NE • ❑ ❑ ❑ ▪ El El El • ❑ ❑ ❑ Comment: The Division received the facility's permit renewal application on 8/21/2019. The last compliance evaluation inspection at this facility was performed by DWR staff on 3/4/2019. Record Keeping Yes No NA NE Are records kept and maintained as required by the permit? • ❑ ❑ ❑ Is all required information readily available, complete and current? • ❑ ❑ ❑ Are all records maintained for 3 years (lab. reg. required 5 years)? • ❑ ❑ ❑ Are analytical results consistent with data reported on DMRs? • ❑ ❑ ❑ Is the chain -of -custody complete? • ❑ ❑ ❑ Dates, times and location of sampling • Name of individual performing the sampling • Results of analysis and calibration • Dates of analysis • Name of person performing analyses • Transported COCs • Are DMRs complete: do they include all permit parameters? • ❑ ❑ ❑ Has the facility submitted its annual compliance report to users and DWQ? ❑ ❑ • ❑ (If the facility is = or > 5 MGD permitted flow) Do they operate 24/7 with a certified operatc ❑ ❑ • ❑ on each shift? Is the ORC visitation log available and current? • ❑ ❑ ❑ Is the ORC certified at grade equal to or higher than the facility classification? • ❑ ❑ ❑ Is the backup operator certified at one grade less or greater than the facility classification' • ❑ ❑ ❑ Is a copy of the current NPDES permit available on site? • ❑ ❑ ❑ Facility has copy of previous year's Annual Report on file for review? ❑ ❑ • ❑ Comment: The records reviewed during the inspection were organized and well maintained. Discharge Monitoring Reports (eDMRs) were reviewed for the period February 2020 through January 2021. No effluent limit violations were reported and all monitoring frequencies were correct. The ORC and staff must ensure to report "No Flow" instead of "0" MGD during all applicable days (throughout each week) on all future eDMRs (Outfalls 004 and 005). Page# 3 Permit: NC0024392 Inspection Date: 03/03/2021 Owner - Facility: McGuire Nuclear Power Plant Inspection Type: Compliance Evaluation Record Keeping Yes No NA NE Laboratory Are field parameters performed by certified personnel or laboratory? Are all other parameters(excluding field parameters) performed by a certified lab? # Is the facility using a contract lab? # Is proper temperature set for sample storage (kept at less than or equal to 6.0 degrees Celsius)? Incubator (Fecal Coliform) set to 44.5 degrees Celsius+/- 0.2 degrees? Incubator (BOD) set to 20.0 degrees Celsius +/- 1.0 degrees? Yes No NA NE • ❑ ❑ ❑ • ❑ ❑ ❑ ❑ ❑ • ❑ Comment: On -site effluent analyses (including field) are performed under Duke Energy's laboratory certification #248 and field laboratory certification #5156. Gel Laboratories (Oil & Grease and TSS) and ETS (toxicity) have also been contracted to provide analytical support. Effluent Sampling Is composite sampling flow proportional? Is sample collected below all treatment units? Is proper volume collected? Is the tubing clean? # Is proper temperature set for sample storage (kept at less than or equal to 6.0 degrees Celsius)? Is the facility sampling performed as required by the permit (frequency, sampling type representative)? Yes No NA NE • ❑ • ❑ • ❑ ❑ ❑ • ❑ ❑ ❑ • ❑ ❑ ❑ • ❑ ❑ ❑ • ❑ ❑ ❑ Comment: The subject permit requires composite (Outfall 001 only) and grab effluent samples. Operations & Maintenance Is the plant generally clean with acceptable housekeeping? Does the facility analyze process control parameters, for ex: MLSS, MCRT, Settleable Solids, pH, DO, Sludge Judge, and other that are applicable? Yes No NA NE • ❑ ❑ ❑ Comment: NPDES facilities appeared to be properly operated and well maintained. No chlorination is added at Outfall 001. Carbon dioxide is used (as -needed basis) for pH adjustment at Outfall 002. Minimal solids are generated on -site due to changes on the water treatment processes. The basins have not been cleaned out in approximately ten years; however, sludge would either be disposed into the on -site permitted landfill (lined) or off -site by a contracted company based on testing results. The facility staff have the capability to discharge (Outfall 005) from a lower pond level (not affected by pH) during the algal growing season. Flow Measurement - Effluent Yes No NA NE Page# 4 Permit: NC0024392 Inspection Date: 03/03/2021 Owner - Facility: McGuire Nuclear Power Plant Inspection Type: Compliance Evaluation Flow Measurement - Effluent Yes No NA NE # Is flow meter used for reporting? • ❑ ❑ ❑ Is flow meter calibrated annually? • ❑ ❑ ❑ Is the flow meter operational? • El El El (If units are separated) Does the chart recorder match the flow meter? ❑ El MI ❑ Comment: Outfall 001 flows are based on pump logs and Outfall 005 instantaneous flows are based on a V-notch weir and staff gauge measurements. Outfall 004 flows are based on calculated tank volumes during the batch discharges. Outfall 002 is equipped with a flume and bubbler type flow meter. The flow meter is calibrated quarterly by Duke Energy's I&E Unit. Outfall 002's flow would be subtracted from the flow measured at Outfall 005 to determine Outfall 005's reportable flow when both outfalls are discharging. Effluent Pipe Is right of way to the outfall properly maintained? Are the receiving water free of foam other than trace amounts and other debris? If effluent (diffuser pipes are required) are they operating properly? Yes No NA NE • ❑ ❑ ❑ ❑ ❑ • ❑ ❑ ❑ • ❑ Comment: Outfalls 001 and 005 were clear with no floatable solids, sheens or foam. Outfall 002 was not discharging at the time of the inspection. The receiving streams did not appear to be negatively impacted. Fish were observed in Outfall 001 and the pond for Outfall 005. Page# 5
