We previously submitted our final certification for the main treatment process along with the record drawings to Alan Klimek, PE. After placing the new system on line, Harris Staff took the old extended aeration system off-line so that the existing steel tanks could be sand -blasted, primed and epoxy -painted. The newly painted tanks were then outfitted with transfer pumps so that they could be used as raw sewage flow equalization basins per the approved final design plans. This work was completed as of June 17, 2005. Please accept this letter as our certification that the final conversion of the old extended aeration package plant to influent flow equalization tanks was completed in accordance with the approved plans and specifications. The Engineering Design Plans and Specifications prepared by McKim & Creed were approved by NCDENR and an Authorization to Construct (#039586A01) was issued on February 27, 2004. During the course of construction, McKim & Creed, P.A. had construction inspectors periodically on-site to monitor and verify that construction was proceeding in compliance with the approved engineering drawings and specifications. These periodic inspections were supplemented using Progress Energy's Resident Construction Inspector.

OF WATER QUALITY DIRECTOR'S OFFICE RE: Engineering Certification of Final Completion; Harris Nuclear Plant - Progress Energy Waste Water Treatment Facility Upgrade NPDES Permit # NCO039586 ATC #039586A01 Dear Mr. Klimek: This letter is to certify that construction of the new biological wastewater water treatment system improvements at Progress Energy's Harris Nuclear Plant in New Hill, NC have now been completed. The new treatment system includes the following major components: 1. Installation of one new 15,000 gpd factory -built extended aeration package wastewater treatment facility to replace the two aging 25,000 gpd plants. 2. Retrofit Existing Treatment Plant #1: Existing tankage has been refurbished and converted into sludge storage tanks to provide 48,000 gallons of supplemental sludge storage and to enhance aerobic digestion prior to disposal. The retrofit included removal of tank partitions, replacement of aeration system, and provisions for sludge' transfer. 3. Retrofit Existing Treatment Plant #2: Existing tankage has been refurbished and converted to raw sewage storage. The 40,000 gallon volume represents 7 days of storage at the current average daily flow of 6,500 gpd. The raw sewage'storage facility will be utilized for emergency raw sewage storage in the event the new treatment facility were to experience a mechanical failure or need to be temporarily taken off-line for routine maintenance. Diversion will be possible via a new set of manual yard valves. The retrofit also included the removal of tank partitions, replacement of aeration system, and provision for raw sewage transfer. 4. Construction of a new modular analytical laboratory and office building. 5. Construction of a duplex sodium hydroxide chemical feed and bulk 'storage system for pH control in the new treatment process. Specifically this included new chemical metering pumps, heated bulk storage tank with spill containment, and a pH feed -back control system using a submersible pH probe in the flow equalization basin to modulate chemical feed rate. 6. Construction of new sodium hypochlorite chemical feed and bulk storage system for disinfection of the secondary effluent from the new treatment process. Specifically this included new chemical metering pumps, bulk storage tank with spill containment, and a 5:10 1 59\01 7740-Pennit101-1 M5Fina[Cert.dw 200 MACKENAN COURT, SUITE 200, CARY, NORTH CAROLINA 27511 TEL 919.233.8091 FAX 919.233.8031 www.mckimcreed.com AA0002667 Mr. Alan Klimek, P.E.

Relocation of the existing polymer storage tank and construction of a new duplex polymer feed system for enhanced flocculation and settling in the clarification process. 8. Slope stabilization and construction of concrete steps to enhance Operator access to the treatment units. 9. Installed (4) new yard lights to improve site lighting. 10. Demolished or replaced all existing mechanical equipment and electrical wiring, conduit, panels and appurtenances. The Engineering Design Plans and Specifications prepared by McKim & Creed were approved by NCDENR and an Authorization to Construct (#039586A01) was issued on February 27, 2004. Construction is now complete and I am providing my Professional Engineering certification via this letter and the attached certification form after completing my final inspection, testing, and system start-up last week. During the course of construction, McKim & Creed, P.A. had construction inspectors periodically on-site to monitor and verify that construction was proceeding in compliance with the approved engineering drawings and specifications. These periodic inspections were supplemented using Progress Energy's Resident Construction Inspector. Together, we performed sufficient inspections and tests both during and after construction to insure work was completed in accordance with the NCDENR-approved Construction Plans and Specifications. The existing treatment system will be taken off-line upon your authorization for new system activation. We trust that this is information is sufficient to allow you to authorize Progress Energy to activate the new wastewater treatment system. On behalf of Progress Energy, we would appreciate your cooperation during the design and construction phases of this project. Please feel free to contact us if you have any questions or need additional information. %"t%%J11611JI1,B0f ® Sincerely, �,'CA V'5-11 McKi re ®� 000 �. a � 10 e 0 BEMs Kevin C.
