Office on March 10, 2010 from Duke Energy (DE) requesting authorization to construct a package -type WWT system to serve the administration building being constructed for the proposed Buck Steam Plant's Combustion Turbine Combined Cycle (CTCC) project. There is an existing package -type treatment system at this facility that currently serves the main. power plant, however, from a logistical standpoint, the piping distance and site constraints make it difficult to collect and treat this proposed domestic waste stream in the existing sanitary sewer.treatment facility. Such being the case, DE has chosen to add a second domestic wastewater treatment system to serve the subject project. This request involves the installation of an extended aeration WWTP consisting of a bar screen, an aeration chamber, a secondary clarifier, a chlorine contact chamber, and an aerated sludge holding tank. The proposed WWT system will be designed to treat a flow of up to 630 gpd and expected to produce an effluent that can meet or exceed the following criteria: BOD5 < 30 mg/l TSS <30 mg/l NH3 < 15 mg/1 Fecal Coliform <200 colonies/100ml Effluent from the proposed WWT facility will be collected in a sump and eventually pumped into Buck Steam Plant's existing secondary ash basin where it will receive further treatment prior to being discharged through outfall 002. Therefore, pending a final technical review and approval by CG&L, it is recommended that the request for an ATC be approved.

Page 3 CALCULATION NUMBER --A shave.° BUKOC-CA-M-WT.00.00-01 10.0 CALCULATION 10.1 Sanitary Sewer Package Plant Sizing The Sanitary Sewer Package Plant will be vendor supplied as a prefabricated unit. The minimum design daily flow of sewage used to calculate the design volume of sewage to size the Sanitary Sewer Package Plant is 25 gallons / person/shift (for factories) + 10 gallons / person (for showers) (Ref. 4.4). Per email from Duke (Attachment C), The Buck Combined Cycle Project has a plant staff of two shifts 12-hr operations shifts with 4 people and one 8-hr maintenance shift with 10 people. Two more people and showers are added for outage periods. Therefore the Design Volume (DV) is given as: DV = [25 gal/person x (4 + 4 +10 +2) people/day + 10gal/person x (4 + 4 + 3 +2) people/day] DV = 630 gallons per day 10.2 Design Water Supply Flow (DWS): The total design water flow to the Administration Building is given by the tabulated supply fixture unit count below.

Per Cameron Hydraulic, for 98 gpm, a 3" sch. 40 new steel pipe provides 3.12 ft of head loss per 100 feet of length at a velocity of 4.34 ft/sec. Therefore, 3" sch. 40 pipe is properly sized for this application. Page 5 CALCULATION NUMBER Shaw _ BUKOC-CA-M-WT.00.00-01 10.5 Drain Pipe Sizing Pipe sizing for the sanitary waste system is based on Attachment B for Discharge Rates for Flowing Partially Full (gravity/channel flow). For the given inputs of 6° HDPE SDR11 piping at 1/8" per foot slope and a Manning Roughness of 0.011, flow results are: Max Flow: 244 gpm 50% Flow: 113 gpm 75% Flow: 207 gpm A drain flow of.74 gpm will result in channel flow in a 6" HDPE SDR11 pipe of about 40% elevation in the pipe. 11.0 RESULTS & CONCLUSIONS Sanitary Treatment System Design Design Water Supply Design Drain Flow Water Supply Pipe Size Drain Pipe Size 630 gpd 98 gpm 74 gpm 3" sch. 40 Carbon Steel 6" HDPE SDR11 t Page 6 ,q i T�,c�tNtt✓ nJT A Sturgies, Bryan From: Pressley, Brent Sent: Monday, December 14, 2009 4:58 PM To: Sturgies, Bryan , Subject: FW: Buck Wastewater Treatment Authorization to Construct Permit Application Duke approves of package plant sizing.

Please clarify the following with regard to shift work at Buck. 1) 14 people per shift: Based on hours per shift and. shifts per day 4 of the 14 max number per shift was. assumed to be operators that could be.on a 12 hour schedule, so there would be 2 shifts per day in that scenario for the 4 operators per shift. The remaining 10 of the 14 max number would be the maximum number of the remainder of station staff working a weekday daytime schedule. These remaining 10 would probably work on average an 8 hour/day schedule, but assume a maximum of 10 hours per day for these remaining 10 to cover OT, alternative schedules for mechanical craft, etc. -.just one shift for these 10: 2) 7 showers per shift: _Based on hours per shift and shifts per day As above, 4 of the 7 showers assumed operators on a 12 hour schedule, so there would be 2 shifts per day in that scenario for the 4 .operators. The remaining 3 of the 7 max number assumed 3. mechanical craft; as . stated above, assume a "maximum of 10 hours per day for these remaining 3 - just.one shift_ per day for these 3. 3) Does your staffing include an allowance. for visitor's? (Cliffside used 8 per day) The numbers above are maximums, so in most cases, there is some.contingency to allow for visitors. I would suggest adding no more than an additional 2 to the. numbers above to cover visitor allowance in . an extreme case (i.e. an outage scenario). Thanks, W.

We know definitively that it will include the sanitary waste treatment system and the oil/water separator. Todd Shuping corresponded to Doug Napadano yesterday that the project will utilize an aerobic packaged treatment system in lieu of the base design septic system. In order to provide timely support to the Authorization to Construct Permit, we want to make sure that Shaw initiates and expedites engineering work on the packaged aerobic system and oil/water separator, including sizing calculations, specification development, and physical layout. Brent Pressley is familiar with the permit documentation requirements as well as the aerobic system design from his work at Cliffside. Our expectation is that the aerobic system will be identical in design to Cliffside but sized for a lower, capacity. The oil/water separator documentation package will contain the same level of information as the sanitary waste water package. Should you have any questions or require additional information, please call. We will communicate any clarifications to the permit submittal.package after our permitting.people have some initial conversations with the State.

Q = 440 gpm 10.2 Wastewater Collection Sump The Wastewater Collection sump.is sized based on having all three sump pumps operate at maximum capacity for three (3) minutes. Using an assumed sump footprint of _15ft x 15ft (assumption 6.1), the minimum operating height of the sump. is determined by: Sump Volume Pump combined flow x time 3 x 440 gpm x 3 minutes = 3,960 gallons The cross sectional area of the sump is 225 soft. For every foot of elevation; there are 225 cuft or 1,683 gallons. Therefore, the minimum operating height -of the 15ft x 15ft sump is given as: Sump Height = Sump Volume / 1,683 gal/ft 3;960 gallons,/ 1,683 gaUft = 2.35 ft = Say aft, 1ft per pump Page 6 CALCULATION NUMBER Shaw® BUKOC-CA WMP.00.00-02 AL Freeboard Grade 663'-0" HH Level, Alarm H.

Wastewater Collection Sump Dimensions: 15ft L x 15ft W x 10ft H 10.3 Sump Pump Design Conditions: The effluent from the wastewater collection sump will need to be pumped to the Secondary Ash Basin with vendor supplied Cantilevered Sump Pumps. The sump pump design conditions are based on the routing and selected size of the distribution piping from the sump to the Secondary Ash Basin. The following assumptions have been made: 1. Process Fluid Water, 60 deg F 2. Pipe 3000 ft of 12" HDPE SDR 13.5 Pipe 3. Pump Elevation 654 ft 4. Grade Elevation 663 ft 5. Secondary Ash Basin 675 ft 6..

The AFT Models predict the following for each case: Case 1 (1 pump operation): 1.,013 gpm @ 53.2.ft TDH Case 2.(2 pump operation): 683 gpm @ 76.0 ft TDH Case 3 :(3 pump operation): 494 gpm @ 84.9 ft TDH Given the results of the three model runs, Case 3 TDH is selected as the design.head. Frictional. Head = Total Head Elevation Head 84.9 ft .— (680 - 654) ft = 58.9 ft For margin, 100/6 (or 6ft). is added to the frictional head. Design Head 84.9ft + 6ft Design Head; = 90.9ft Say 91ft Therefore the design point of the pump is 440 gpm @ 91ft TDH.
