SHEARON HARRIS NUCLEAR POWER PLANT UNIT 1 ANNUAL ENVIRONMENTAL (NONRADIOLOGICAL)

OPERATING REPORT January 1, 2006 through December 31, 2006 Docket No. 50-400 Facility Operating License No. NPF-63 Appendix B

1.0 INTRODUCTION

Carolina Power & Light Company (CP&L) received a low-power Facility Operating License (No. NPF-53) and full-power Facility Operating License (No. NPF-63) for the Shearon Harris Nuclear Power Plant, Unit 1, from the U.S. Nuclear Regulatory Commission (NRC) on October 24, 1986, and January 12, 1987, respectively.

Appendix B (the Environmental Protection Plan [nonradiological]) of the full-power license requires submittal of an Annual Environmental (nonradiological) Operating Report to the NRC describing the implementation of the plan during the previous year.

The purpose of this document is to fulfill the requirement for the period January 1 through December 31, 2006.

On January 1, 2003, Carolina Power & Light Company adopted the brand name Progress Energy Carolinas, Inc.

2.0 PLANT CONSISTENCY REQUIREMIIENTS [EPP Section 3.0]

2.1 Plant Design and Operation There were no changes in plant design or operation and there were no tests or experiments performed which involved a potentially significant unreviewed environmental question during the reporting period.

2.2 Reporting Related to the NPDES Permit Required National Pollutant Discharge Elimination System (NPDES) monitoring data were submitted to the NCDWQ via monthly discharge monitoring reports and separate correspondence as warranted.

Harris Nuclear Plant (HNP) submitted an application for renewal of the NPDES Permit to the North Carolina Department of Environment and Natural Resources (NCDENR) on January 30, 2006. HNP submitted a copy the renewal application to the NRC by letter dated February 10, 2006.

HNP operated under the current NPDES Permit with an expiration date of July 31, 2006, for the remainder of 2006 because the renewal application submittal requirements had been met (i.e., submitted at least 180 days prior to expiration).

HNP received a draft copy of the NPDES Permit from the NCDENR for review and comment on July 27, 2006. HNP responded to the draft NPDES permit with comments on August 22, 2006. The NCDENR subsequently issued the renewed permit on February 9, 2007, with an effective date of March 1, 2007.

On April 17, 2006, the NCDWQ issued Pump and Haul Permit WQ0030120 to allow transfer of sewage from the HNP Sewage Treatment Plant (Outfall 002) to the Harris Energy & Environmental Sewage Plant (Outfall 007) during Refueling Outage 13. Reporting and termination requirements of the permit were met.

3.0 UNUSUAL OR IMPORTANT ENVIRONMENTAL EVENTS [EPP Section 4.1 ]

No occurrence of an unusual environmental event that would indicate or could result in a significant environmental impact causally related to plant operations occurred during the reporting period. No releases or exceedances of permit conditions caused any significant environmental impact. The existence of biofouling organisms (Asiatic clams, Corbicula fluminea) and the presence of troublesome aquatic vegetation (hydrilla, Hydnilla verticillata)in Harris Reservoir were considered important topics worthy of inclusion in this report.

3.1 Aquatic Biological Monitoring A. Inspections for Asiatic clams (Corbiculafluminea) in the Harris Nuclear Plant Emergency Service Water System (e.g., intake structures)

The frequency for inspecting the Emergency Service Water (ESW) intake structure was changed to once every 3 years during 2003. The change was based on an engineering evaluation (Engineering Change 49074) of HNP's Generic Letter 89-13 Testing and Inspection Program. Inspection of two ESW intake bays (one from each reservoir) occurred on April 23, 2006, and December 13, 2006. These inspections indicated a stable Asiatic clam population.

No clogging events of HNP cooling water systems occurred during 2006 as a result of Asiatic clam infestation.

B. Monitoring for hydrilla (Hydrillaverticillata),a nonnative aquatic weed On November 29, 2006, a visual aquatic vegetation survey of the shoreline was conducted in the Thomas Creek arm of the Harris Reservoir and in the HNP intake canal. Similar to previous years, the dominant aquatic vegetation was hydrilla and water primrose (Ludwigia spp.). The area coverage of both aquatic weeds was similar to 2003, 2004, and 2005. No additional habitat colonized by either species was observed and controls such as herbicide or grass carp do not appear to be needed at this time.

The shoreline of the HNP auxiliary cooling reservoir intake canal was surveyed on December 1, 2006, and no hydrilla was found. Neither was hydrilla found at other locations in the auxiliary cooling reservoir including the back portions of the reservoir. The population size of grass carp (Ctenopharyngodon idella) was sufficient to prevent the infestation and spread of hydrilla in the auxiliary cooling reservoir in 2006. Two native species of vegetation (slender spikerush, Eleocharis baldwinii, and babys-tears, Micranthemum spp.) were observed growing in the shallow protected coves in the reservoir. Neither species pose operational problems for the HNP since they are small rooted plants that do not form floating mats of vegetation capable of affecting intake operations.

No impacts to HNP operations from aquatic vegetation occurred in 2006.

3.2 Combined Construction and Operating License Application Evaluations Progress Energy Carolinas, Inc. is evaluating potential sites for two new nuclear plants on HNP property. Core samples were collected and additional motoring wells were installed during 2006. These activities were coordinated with the NCDENR.

No impacts to HNP operations were caused by these activities.

4.0 ENVIRONMENTAL MONITORING [EPP Section 4.2]

4.1 Aquatic Monitoring [EPP Section 4.2.1 ]

Under the authority of the Clean Water Act, the state of North Carolina issued a National Pollutant Discharge Elimination System (NPDES) permit (NC0039586) for the HNP on May 1, 2002, that remained in effect during 2006. The permit includes the Harris Energy & Environmental Center (HE&EC) sewage treatment plant discharge as an outfall (007).

The permit requires that a state-certified laboratory perform the analyses on all non-field parameters analyzed for effluent samples. In accordance with this requirement, the HNP Environmental & Chemistry Laboratory was certified by the NCDWQ as a Wastewater Laboratory, effective January 1, 2006, and valid through December 31, 2006. In addition, during 2006 the Progress Energy Chemistry Laboratory at the HE&EC contracted with two NCDWQ-certified private laboratories, Tri-Test Laboratories and Environmental Testing Solutions, Inc., to perform analyses.

4.1.1 Effluent Monitoring Routine effluent monitoring was conducted and reported to the NCDWQ as required by the NPDES permit. One NPDES sampling opportunity was missed during August 2006, and was reported to the NCDWQ as required by the permit.

4.1.2 NPDES Inspections On March 14, 2006, a maintenance inspection was conducted at the Harris Energy

& Environmental Sewage Plant Field Laboratory (Certificate Number 5145) by the NCDWQ. One comment and one deficiency were identified as a result of the inspection. Both items were addressed by the laboratory.

On June 13, 2006 a compliance evaluation inspection was conducted at the Harris Nuclear Plant by the NCDWQ. No deficiencies were identified as a result of the inspection.

4.2 Terrestrial Monitoring [EPP Section 4.2.2]

Terrestrial monitoring is not required.

43 Noise Monitoring [EPP Section 4.2.3]

Noise monitoring is not required.

5.0 EPP AUDIT [EPP Section 5.1]

An audit conducted by an independent corporate entity was performed to verify the completeness and accuracy of the conditions and activities described in this annual environmental operating report. The results of the audit are on file and available for inspection.

6.0 PLANT REPORTING REQUIREMENTS [EPP Section 5.4]

6.1 EPP Noncompliances There were no EPP noncompliances identified during the reporting period. One NPDES sampling opportunity was missed (Section 4.1.1) during 2006, which was reported to the NCDWQ as required by the NPDES permit.

6.2 Changes in Station Design and Operation There were no changes in station design or operation and there were no tests or experiments performed which involved a potentially significant unreviewed environmental question during 2006.

6.3 Non-routine Reports There were no non-routine reports submitted in accordance with EPP Section 5.4.2 during 2006.

6.4 Other Reporting Requirements There were no other EPP reportable events during 2006.
