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 (SHNPP), 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 fulfillthe requirement for the period January 1-December 31, 1995.

2.0 PLANT CONSISTENCY REQUIREMENTS [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 Allrequired NPDES monitoring data were submitted to the North Carolina Division of Environmental Management (NCDEM) via monthly discharge monitoring reports and separate correspondence as warranted.

3.0 UNUSUAL OR IMPORTANT ENVIRONMENTALEVENTS [EPP Section 4.1]

No occurrence of an unusual or important environmental event that would indicate or could result in a significant environmental impact causally related to plant operation occurred during the reporting period. No releases or exceedances of permit conditions caused any significant environmental impact.

4.0 ENVIRONMENTALMONITORING [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 reissued a National Pollutant Discharge Elimination System (NPDES) permit (NC0039586) for the SHNPP on November 1, 1991, that remains in effect until March 31, 1996. A permit modification was issued on March 31, 1995, by the N.C. Department of Environment, Health, and Natural Resources to change the monitoring frequency for several effluent characteristics from daily to three times a week for the Harris Sanitary Waste Treatment Plant. An NPDES permit renewal application for this

0 'j modified permit was submitted on October 3, 1995. The current permit reflects a reclassification of the facility from a Class II to a Class III designation. The Class IIIdesignation requires that the laboratory analyses performed on all effluent samples be performed by a laboratory certified by the state. In accordance with this requirement, the SHNPP Environmental & Chemistry Laboratory was certified by the NCDEM as a Wastewater Laboratory, effective January 1, 1995, and the certification is valid through December 31, 1997. The Toxicity Testing Laboratory and the Chemistry Laboratory at the Harris Energy & Environmental Center were also certified by the NCDEM for toxicity testing and wastewater analyses, respectively to support the SHNPP operations. The Toxicity Testing Laboratory certification was valid under two certifications from November 1, 1994, through November 1, 1995, and from November 1, 1995, through November 1, 1996. The Chemistry Laboratory certification was renewed on January 1, 1995, and is valid through December 31, 1997. In addition, during 1995 the Chemistry Laboratory at the Harris Energy & Environmental Center contracted with two private laboratories, Webb Technical Group and Industrial and Environmental Analysts, Inc., to perform some of the analyses.

4.1.1 F<ffiuent Monitorin Routine effluent monitoring was conducted and reported to the NCDEM as by the NPDES permit. NPDES noncompliances that occurred 'equired during 1995 were:

A. c I 'nati n em ea lin T werBa in wd Weir In accordance with Part II, E (7) of the NPDES Permit, an attachment was made to the August Discharge Monitoring Report to provide information regarding a small leak in the dechlorination system at the SHNPP cooling tower basin blowdown weir.

On August 22, 1995, SHNPP personnel discovered a small leak in the dechlorination system at the cooling tower basin blowdown weir. The leak, which drained into the nearby stormwater system, was composed of cooling tower basin water with ammonium bisulflite added as the dechlorination agent. The system was immediately shut down, which stopped the leak, and the failed ball valve replaced. Because a redundant feed system was in place, adequate dechlorination of the cooling tower blowdown continued to ensure that the NPDES permit limitations for chlorine were met. Feed equipment is scheduled to be replaced by ESR-95235. The exact volume and duration of the leak could not be determined. Plant personnel estimated that the maximum volume was less than 1000 gallons. The incident is an "Other

Noncompliance" as defined by the SHNPP's NPDES permit. No harm to the environment or human health occurred during or after the discharge.

B. Elevated Zinc In accordance with Part II, E (9) (a) of the NPDES Permit, notification concerning a zinc excursion at the SHNPP cooling tower blowdown (Outfall No. 001) was reported to the Raleigh Regional Office of the NCDEM by telephone on September 11, 1995, with follow-up notification made by letter on September 13, 1995.

On September 8, 1995, plant personnel discovered zinc concentrations of approximately 3 parts per million (ppm) in the cooling tower blowdown discharge. The zinc limit prescribed in the NPDES Permit is 1 ppm. The elevated zinc level in the discharge was the result of a decrease in the pH of the cooling tower water. Plant personnel subsequently adjusted the pH of the cooling tower water and returned the zinc concentration to within the permitted concentration on September 10, 1995. No harm to the environment or human health occurred during or after the discharge. This is based on detected zinc levels of 0.26 ppm at the outfall to Harris Lake.

C. ut of ecificati n D In accordance with Part II, E (7) of the NPDES Permit, an attachment was made to the December Discharge Monitoring Report to provide information regarding the out of specification BOD, (Biological Oxygen Demand - 5 day) value sampled from outfall 002 on December 28, 1995. The cause of this condition was unknown. Due to the sample date of December 28, 1995, the technical laboratory did not complete the analysis and provide results back to SHNPP until January 11, 1996. BOD, analysis results &om samples taken on December 27, 1995, and December 29, 1995, were well within permit limitations. Also, during this time period, all other wastewater facility operating parameters, including total suspended solids, indicated that the facility was operating properly. Based on this, no actions were considered necessary.

4.1.3 uatic Biolo ical nitorin On April 13, 1995, twenty-two Asiatic clams were collected from immediately behind the intake screens of the Emergency Service Water Intake Structure Bay 6. Additionally, thirteen Asiatic clams were collected from immediately behind the intake screens of the Emergency Service Water Intake Structure Bay 8. The estimated density at each location was 948 and

0 0 537 clams/m', respectively. Asiatic clams were also collected from the Auxiliary Reservoir Intake Canal, approximately 20 meters from the Emergency Service Water Screening Structure (estimated densities were 43 clams/m') and from the mouth of the Main Reservoir Intake Canal (estimated densities were 14 clams/m'). No clams were collected from the .

Service Building fire protection system.

Fall sampling for Asiatic clams was conducted on November 20, 22, and 30 1995. Twenty-six live clams and the equivalent of 137 deceased clams represented as shells were collected immediately behind the intake screens of the Cooling Tower Makeup Pump 1X. These clam shells may indicate that clams are accumulating in this area. No Asiatic clams were collected from immediately behind the intake screens of the Emergency Service Water Intake Structure Bays 6 and 8. Asiatic clams were collected from immediately behind the intake screens of the Emergency Service Water Screening Structure with 43 and 216 clams/m'ollected from Bays 6 and 8, respectively. All clams were estimated to be approximately 2 to 3 years in age. Asiatic clams were also collected from the Auxiliary Reservoir Intake Canal (Station AI), approximately 20 meters from the Emergency Service Water Screening Structure. Estimated densities at this location were 201 clams/m~. At the mouth of the Auxiliary Intake Canal (Station Zl) clams were collected at densities of 57 organisms/m~. Asiatic clams were also collected approximately 50 meters downstream of the Emergency Service Water Intake Structure (Location MI) at estimated densities of 14 clams/m~. No clams were collected by sampling at the mouth of the Main Reservoir Intake Canal (Station V3) or in the Service Building fire protection system.

Asiatic clams caused no biofouling of plant water systems during 1995.

During 1995 monitoring for zebra mussels Dreissena polymorpha and quagga mussels D. bugensis was conducted in areas of likely infestation, i.e.,

Hollemans Crossroads boat ramp and water quality station marker buoys at Transects E and P. Visual observations for zebra and quagga mussels were conducted at the Main and Auxiliary intake structures during sampling for Asiatic calms. No zebra or quagga mussels were found during 1995.

Since 1988 hydrilla Hydrillaverticillata, a nonnative aquatic weed, has been established in Harris Lake. A visual survey made during November 1995, reconfirmed that hydrilla was established in water less than 3 m deep in all major arms of the reservoir. The total areal coverage was estimated to be approximately 475 ha. This coverage was 30 ha greater than that during the

~

p

fall of 1994. The majority of this increased coverage occurred in the Buckhorn Creek arm of the reservoir.

A visual survey was also conducted in the auxiliary reservoir during November. Although 800 grass carp Ctenopharyngodon idella were stocked in October 1994, to control hydrilla, it continued to spread in the auxiliary reservoir. Most of the shoreline in the bay receiving discharges from the SHNPP is colonized to a depth of 3 m. It appears that moderate control has occurred in the bay of the auxiliary reservoir (this bay received the 800 grass carp stocked, in 1994). It is possible that the grass carp did not control hydrilla in the discharge receiving bay because they did not migrate into that area. Both bays are connected by a narrow channel. No grass carp were stocked in 1995; however, plans are to stock 800 grass carp in 1996.

Monitoring of the effectiveness of these stockings will determine necessity for future stocking.

No impacts to SHNPP operations from hydrilla have occurred nor are they expected because of the low velocity of water drawn from the main lake into the cooling tower makeup water intake structure.

4.2 Terrestrial Monitoring [EPP Section 4.2.2]

Terrestrial monitoring is not required.

4.3 Noise Monitoring [EPP Section 4.2.3]
