OPERATING RE<PORT APPENDIX 8 for January 1- December 31, 1998 CAROLINAPOWER A LIGHT COMPANY Docket No. 50-400 Facility Operating License No. NPF-63
1.0 'NTRODUCTION 1
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 fulfill the requirement for the period January 1-December 31, 1998.
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 Required NPDES monitoring data were submitted to the North Carolina Division of Water Quality (NCDWQ) via monthly discharge monitoring reports and separate correspondence as warranted.
3.0 UNUSUAL OR IMPORTANT ENVIRONME<NTALE<VENTS [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 fluminae); the presence of troublesome aquatic vegetation (hydrilla, Hydrilla verticillata);
an evaluation of threatened and endangered species reported at the Harris Nuclear Plant (HNP) site, surveys for red-cockaded woodpecker presence or activity on HNP property, and an evaluation of angler success and harvest of the Harris Lake fishery were considered important events worthy of inclusion in this report.
3.1 A uatic Biolo ical Monitorin A. Scheduled semiannual monitorin for Asiatic clams Corbicula umina in the Harris Nuclear Plant HNP Emer enc Service WaterS stem e.. intake structures and the Fire Protection S stem.
Biological Assessment Unit (BAU) personnel conducted the first of two scheduled semiannual sample collections for Asiatic clams (Corbicula flu>nina) in
"I 1 the HNP Fire Protection System on April 21, 1998 and the Emergency Service Water System (e.g., intake structures) on April 29, 1998. No live clams were collected from the Main Reservoir Intake Structure (MRIS) Service Water System or the Cooling Water Makeup Bays. Dead clams (as represented by shells) were collected from Service Water System Bays 1B-SB and 1A-SA. No other biofouling organisms were collected from the MRIS. Asiatic clams were collected from the Auxiliary Service Water System Bay 1 and dead clams in Bay
- 6. Actual numbers collected were 4 clams at Bay 1 with an estimated density of 2
172 clams/m . Dead clams in Auxiliary Service Water System Bay 6 were 2
estimated at 129 clams/m . All clams were estimated to be approximately 1 to 4 years in age. No other biofouling organisms were collected from the Auxiliary Service Water System. No clams or biofouling organisms were collected in the Service Building fire protection system.
During the fall of 1998, the HNP Generic Letter (GL) 89-13 Program Manager informed BAU personnel that inspections of intake bays via procedure EPT-168 are performed as part of the GL 89-13 program and satisfies commitments of the GL 89-13 program. Therefore the fall sampling for Asiatic clams by BAU personnel was canceled. The GL 89-13 inspections completed in the fall of 1998 indicated the presence of live Asiatic clams in both the Main Reservoir Intake Structure and the Emergency Service Water Screening Structure. However, the number of clams observed do not pose an operational problem to plant equipment.
No live clams were found during routine heat exchanger inspections. Future inspections will be conducted via EPT-168 and will be scheduled and implemented in conjunction with the GL 89-13 program.
B. Monitorin for h drilla H drilla verticillata a nonnative a uatic weed durin 1998.
A visual survey for hydrilla which included observations made from a boat and the shoreline of the Harris Nuclear Plant (HNP) main reservoir intake canal was conducted during November 8, 1998. During this survey no attached stands of hydrilla extending to the water surface were observed in the HNP main reservoir intake canal. No impacts to HNP operations from hydrilla occurred during 1998.
BAU Personnel conducted an annual troublesome aquatic vegetation (hydrilla) survey of the Harris Auxiliary Reservoir on November 17, 1998. The survey involved a visual inspection of selected shoreline areas of the reservoir and the shores of the Harris Nuclear Plant auxiliary reservoir intake canal. Unlike 1996 when most shoreline areas of the discharge side of the reservoir had a band of hydrilla extending to the water surface, no area of the auxiliary reservoir or intake canal shoreline had visible stands of Hydrilla reaching the surface. The stocking of 800 grass carp, Ctenopharyngodon ideIla, during the fall seasons of 1994, 1996, and 1997 appears to have resulted in the effective control of hydrilla in the Harris Auxiliary Reservoir and intake canal. This control of aquatic vegetation is expected to last for the next several years.
0 C. 'valuation of threatened and endan ered s ecies re orted at the Harris Nuclear Plant.
BAU personnel conducted a self assessment evaluation of the threatened and endangered species reported at the Harris Nuclear Plant. This self-assessment evaluation of the Harris Nuclear Plant shows there is only one federally protected species (Red-cockaded woodpecker) that could be impacted by plant operations, facility expansion, or other activities. Recommendations for reducing impact to this species include an assessment for occurrence on site of this species if facility expansion or construction require removal of pine trees.
D. Surve s for red-cockaded wood ecker resence or activit on Harris Nuclear Plant ro ert In 1985, Carolina Power & Light Company (CPL) entered into an agreement with the North Carolina Department of Natural Resources and Community Development (currently the North Carolina Department of Environment and Natural Resources) to register and protect a natural area on Harris Nuclear Plant (HNP) property that was occupied by a colony of red-cockaded woodpeckers, a federally endangered species. Systematic surveys by CP&L and North Carolina State University (NCSU) biologists conducted during 1987 and intermittent site inspections by CP&L biologists in subsequent years failed to find any new evidence of red-cockaded woodpecker activity. During March and July of 1998, CP&L biologists inspected the known cavity trees for the presence of the birds and for signs of any recent use. No birds were seen and no signs of red-cockaded woodpecker activity were observed. During the July 1998 red-cockaded woodpecker site visit, the entire area was systematically searched for previously unknown nest cavity trees. None were found. Recent communications with NCSU wildlife extension personnel, the North Carolina Wildlife Resources Commission Nongame Wildlife Program staff, the U.S. Fish & Wildlife Service staff, and staff of the North Carolina Division of Parks and Recreation indicate no knowledge of the birds inhabiting the site since the late 1980s.
E. Access- oint creel surve of Harris Lake fishe From July 1, 1997, through June 30, 1998, the North Carolina Wildlife Resources Commission (NCWRC) conducted an access-point creel survey on Harris Lake.
The purpose of this survey is to determine angler success and harvest of the Harris Lake fishery. A report summarizing the results of the survey is expected to be issued by NCWRC during the second or third quarter of 1999 (personnel communication, Mr. Scott Van Horn, NCWRC). A portion of the funds for the survey were contributed by the Harris Nuclear Plant.

4.0 '<NVIRONMENTALMONITORING [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 Harris Nuclear Plant (HNP) on September 1, 1996, that remains in effect until March 31, 2001. This permit includes the CP&L Harris Energy &
Environmental Center (HE&EC) sewage treatment plant discharge as an outfall (007). This permit requires that the laboratory analyses performed on all non-field parameters determined for effluent samples be performed by a state-certified laboratory. In accordance with this requirement, the HNP Environmental &
Chemistry Laboratory was certified by the North Carolina Department of Water Quality (NCDWQ) as a Wastewater Laboratory, effective January 1, 1998, and valid through December 31, 2000. The Toxicity Testing Laboratory at the CP&L HE&EC was also certified by the NCDWQ for toxicity testing to support the HNP operations. This laboratory was certified to perform testing under two consecutive Biological Toxicity Laboratory certifications effective November 1, 1997, through November 1, 1998, and November 1, 1998, through November 1, 1999. In addition, during 1998 the CP&L Chemistry Laboratory at the Harris-Energy & Environmental Center contracted with a NCDWQ-certified private laboratory, Aqua Tech Environmental Laboratories to perform analyses.
4.1.1 E<ffluent Monitorin Routine effluent monitoring was conducted and reported to the NCDWQ as required by the NPDES permit. The reportable event was:
A. Au ust 26 1998 Biochemical Ox en Demand result outfall 007 elevated.
The effluent sample obtained from outfall 007 at the Harris Environmental
& Energy Center on August 26, 1998, resulted in an elevated Biochemical Oxygen Demand (BOD5) value of 23 mg/L. This value exceeded the permit limit of 22.5 mg/L. The (BOD5) value for the week before the exceedence was ( 2 mg/L and the value was ( 3 mg/L on September 1, 1998.
CP&L personnel performed an investigation to determine the cause of this exceedence and to identify corrective actions to prevent recurrence. The investigation was unable to conclusively identify a root cause, but it did determine that there were no apparent inappropriate actions by wastewater treatment personnel. The most likely contributing factors for the elevated (BOD5) levels were a combination of climatic conditions (excessive temperature and intensive sunlight on the ponds), the inherent uncertainty of a biological system, increased algal growth due to the climatic
- ~ l conditions and a slight increase (though well below permit limits) in ammonia values. Corrective actions included increasing the frequency of removing algal growth during the summer months and developing and implementing a trending process to identify changes in ammonia values during discharges.
4.2 Terrestrial Monitoring [EPP Section 4.2.2]
Terrestrial monitoring is not required.
4.3 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 that audit are summarized in the attached letter.
6.0 PLANT REPORTING REQUIREMENTS [EPP Section 5.4]
6.1 EPP Noncompliances There were no EPP noncompliances identified during the reporting period. There was one NPDES noncompliance as discussed in Section 4.1.1, Item A.
6.2 Changes in Station Design 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.
6.3 Nonroutine Reports There were no nonroutine reports submitted in accordance with EPP Section 5.4.2. There was one NPDES reportable event (Sec. 4.1.1, Item A) identified during the reporting period.
c April 1, 1999 Mr. Benjamin C. White Manager - Environmental Services Operations and Environmental Support Department
Dear Mr. White:
A review of the Hams Nuclear Plant Unit 1 (HNP) Annual Environmental (Nonradiological) Operating Report was recently completed. 'Ihe report is issued annually to comply with the reporting requirements of the U. S. Nuclear Regulatory Commission (NRC) established in Appendix B, Environmental Protection Plan (Nonradiological), of the HNP Facility Operating License No. NPF-63. The objective of the review was to assess the accuracy and completeness of the report for the period January 1, 1998, through" December 31, 199S.
The scope of our work was limited to a review of the supporting documents related to the Report and interviews with HNP and Environmental Services personnel. Based on the audit procedures performed, the Annual Environmental (Nonradiological) Operating Report appears to be complete, accurate, and in compliance with NRC reporting requirements.
