GROUNDWATER MONITORING WELL APPLICATION AND VARIANCE REQUEST Duke Energy Oconee Nuclear Station 155 East Pickens Highway Seneca, South Carolina 29672 DHEC Facility ID 00535 S&ME Project No. 1264-07-234

Dear Ms. Cooke:

Attached is the S CDHEC Monitoring Well Application for the installation of twenty-eight (28) groundwater monitoring wells at Duke Energy's Oconee Nuclear Station located near Seneca, South Carolina. S&ME, Inc. is submitting this application on behalf of Duke Energy. The groundwater monitoring wells will be installed at the approximate locations depicted/described on the attached Drawings GM-O- 1 (Revision

4) and GM-O-2 (Revision 3). The groundwater monitoring wells will be constructed in accordance with the attached Drawings GM-O-3 (Revision

2) and GM-O-4 (Revision 1).These monitoring wells will be installed as part of a groundwater protection monitoring system at each of Duke Energy's nuclear power plants. The purpose of the environmental groundwater protection monitoring system is to provide detection of radioactive leaks to minimize the potential for migration of radioactive isotopes (particularly tritium) in groundwater.

The installation of these wells is scheduled to begin on September 17, 2007 and is anticipated to be completed in December 2007. The wells will be installed to monitor the groundwater in the zone above bedrock (13 wells), in the upper bedrock region (13 wells, designated with "R" after the well number), and in the deeper rock region (2 wells, designated with "DR" after the well number).S&ME, INC. / 155 Tradd Street / Spartanburg, SC 29301 / p 864.574,2360 t 864.576.8730 1 Marcus Drive, Suite 301 / Greenville, SC 29615 /p 864-232-8987 / www.smeincmcom Groundwater Monitoring Well Application and Variance Request S&ME Project 1264-07-064 Duke Energy Oconee Nuclear Station Seotember 2007 On behalf of Duke Energy, S&ME also requests a variance from the South Carolina Well Standard R.61-71 for the wells installed at this site, as noted below: Variance Request S&ME requests a variance from Rule R.61-71 H. 2. a. (1) for wells installed at this site with flush mount well vaults. Due to site traffic in areas where these wells are to be located, all of the wells at Catawba Nuclear Station will be installed with flush mount well vaults. This rule states that permanent conventionally installed monitoring wells shall be grouted from the top of the bentonite seal to the land surface. Detail C on the attached DrawingGM-O-3 shows the construction details for the Flush Mount Well Vault. This detail shows the grout terminating one (1) foot to one and one-half (11/2) feet below the bottom of the concrete pad. The borehole space in this region would be filled with a washed river-rock to the bottom of the concrete pad. The purpose of this rock is to provide a pathway for rainfall that may leak past the well vault cap to drain out of the vault.On behalf of Duke Energy, we appreciate your consideration and look forward to your response. If you have questions on this request, please contact me at your convenience. Sincerely, S&ME, Inc.William M.

TEMPORARY GROUNDWATER MONITORING WELL APPLICATION AND VARIANCE REQUEST Duke Energy Oconee Nuclear Station 7800 Rochester Highway Seneca, South Carolina 29672 DHEC Facility ID 00535 S&ME Project No. 1264-08-195

Dear Ms. Cooke:

Attached is the SCDHEC Monitoring Well Application for the installation of up to 15 temporary groundwater monitoring wells at Duke Energy's Oconee Nuclear Station located near Seneca, South Carolina. S&ME, Inc. is submitting this application on behalf of Duke Energy.These monitoring wells will be installed, supplemental to the Groundwater Protection Initiative of 2007, to further evaluate site conditions. In particular, the focus of these temporary wells is to evaluate (1) potential source and/or (2) extent of tritium detected in well GM-7. The temporary groundwater monitoring wells are planned at the approximate locations depicted on the attached Figure 1. Actual locations may be adjusted in the field based on field conditions. The wells will be installed to monitor shallow groundwater at the site and will be installed as temporary wells by direct-push technology. Figure 2, Temporary Saprolite Monitoring Well Construction Detail Installed by Direct-Push Technology is also attached.The installation of the 15 temporary wells is scheduled to begin on April 28, 2008 and will require approximately two (2) weeks. The temporary wells will be sampled upon installation. Laboratory analysis for tritium will require approximately two (2) weeks.Upon receipt of laboratory results, a second round of sampling/analysis from the temporarywells is planned, which will require approximately two (2) weeks. During this S&ME, INC./ 155 Tradd Street / Spartanburg, SC 29301 / p 864,574.2360 f 864.576.8730 1 Marcus Drive, Suite 301 / Greenville, SC 29615 / p.864-232-8987 / www.smeinc.com Groundwater.Monitoring Well Application and Variance Request S&ME Project 1264-08-195 Duke Energy Oconee Nuclear Station April 2008 period, Duke Energy will also survey locations and top-of-casing elevations of the temporary wells to allow for water level information to be incorporated into groundwater potentiometric mapping for the site. Upon receipt of the laboratory results from the second sampling round, we anticipate abandoning the temporary wells, which will require approximately one (1) week. In support of this planned schedule, we respectfully request, on behalf of Duke Energy, a variance from the South Carolina Well Standards R.61-71, as noted below: Variance Request S&ME requests a variance from Rule R.61-71 H. 4. c. (1) for abandonment of temporary wells installed at this site. This rule states that temporary monitoring wells shall be abandoned within five (5) days of borehole completion. In support of the schedule outlined above, we respectfully request allowance for the temporary wells to remain in-place approximately 45 days. During this period, the wells will be protected by placement of a water tight cap and covered with a protective traffic cone. Further, we offer that these temporary wells are installed inside the outer protective perimeter of the Oconee Nuclear Station.On behalf of Duke Energy, we appreciate your consideration and look forward to your response.
