SHEARON HARRIS NUCLEAR POWER PLANT UNIT 1 ANNUALENVIRONMENTAL(NONRADIOLOGICAL) OPERATING REPORT for January 1, 1990-December 31, 1990 CAROLINAPOWER 8c LIGHTCOMPANY Docket No. 50-400 Facility Operating License No. NPF-63
I 1
1.0 Introduction Carolina Power & Light Company (CPScL) received a low-power Facility Operating License (No. NPF-53) and a full-power Facility Operating License (No. NPF-63) for the Shearon Harris Nuclear Power Plant, Unit 1 (SHNPP), from the U.S. Nuclear Regulatory Commission (NRC) on October 24,
- 1986, and January 12,
- 1987, respectively.
Appendix B of both licenses, the Environmental Protection Plan (nonradiological), required 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 fulfillthat requirement for the period of January 1, 1990, through December 31, 1990.
2.0 Environmental Monitorin 2.1 Aquatic Monitoring
[EPP Section 4.2]
Under the authority of the Clean Water Act, the state of North Carolina renewed the National Pollutant Discharge Elimination System (NPDES) Permit (No. NC0039586) on January 18, 1990, with an expiration date of March 31, 1991. A renewal application was submitted to the North Carolina Division of Environmental Management (NCDEM) on September 27, 1990.
The current permit continues in effect until NCDEM issues the new permit.
2.1.1 EfQuent Monitoring Routine effluent monitoring was conducted and reported to NCDEM as required by the permit.
Out of approximately 1,250 samples collected, there were approximately 4,100 analyses performed.
The following is a summary of NPDES noncompliances that occurred during 1990:
A. A sewage treatment facilityeffluent sample collected on February 9, 1990, exceeded the permit limitfor pH. The cause of this excursion was a mechanical problem with a temporary pump that was being used while the standard pump was being repaired.
The sodium hydroxide feed into the reaeration basin malfunctioned.
B.
The cooling tower blowdown efQuent exceeded chlorine limits on May 25, 1990. The dechlorination pumps were adjusted to minimize the chlorine discharge.
C.
On June 6, 1990, construction personnel were excavating earth above the condenser circulating water piping that returns to the cooling tower.
The construction crew accidentally dislodged one of the
connections causing a leak of 100'F water, which constituted an unpermitted discharge that flowed overland into the lake. The water flow varied between 200-2500 gallons/minute, and after 8'/z hours, the leak was isolated. The water released met NPDES requirements for the cooling tower blowdown discharge. No stressed or dead fish were observed at the affected area.
D. The sanitary sewage treatment eKuent was out of compliance for fecal coliform on July 11, 1990.
There was no indication that the treatment plant was experiencing an operational upset.
We believe that the sample was inadvertently contaminated during sampling or analysis.
There was 0.4 mg/liter of free available chlorine in the sample.
Because of this concentration of chlorine, it would be unlikely that coliform could have been in the sample.
E.
During November and December 1990, the Harris Nuclear Project experienced leaking tubes in the condenser requiring the east and west condenser water boxes to be drained several times for inspection and repair.
Water samples were collected and analyzed prior to each release to ensure the discharged water met NPDES discharge criteria for cooling tower blowdown. This discharge is not currently permitted but has been addressed in the permit renewal application.
F.
The low-volume waste effluent was out of compliance for oil and grease on December 3,
1990.
This was due to a temporary overloading of the oily waste separator.
AllNPDES noncompliances were corrected promptly and were not of an ongoing nature.
Allnoncompliances were reported to NCDEM with no additional actions required by NCDEM.
2.1.2 Biological Monitoring Routine biological monitoring at Harris Lake during the week of October 22, 1990, indicated that the major concentrations of Asiatic clams Corbicula fluminea were still in the vicinity of the two public boat ramps.
Observations indicate that the clams have continued to spread slowly throughout Harris Lake.
A sampling program is in place to monitor the density and distribution of the clams in the lake, intake
- canals, and intake structures.
A single Asiatic clam was found approximately 50 meters from the main intake trash racks but none were found in the intake structures.
I
Routine sampling of Harris Lake in 1988 revealed that hydrilla Hydrilla verticillata, a nonnative aquatic weed, has become established in the White Oak Creek arm of the lake. Herbicide applications made during 1988, 1989, and 1990 failed to arrest its spread. A survey of the lake in the fall of 1990 revealed that hydrilla has spread to all major arms of the lake except for the Buckhorn Creek arm (the southernmost) and it has not been detected in the auxiliary reservoir.
In the areas of the lake where it has become established, hydrilla grows in a band varying in width from less than 20 to several hundred feet along the shore, with the width of the band dependent on the depth of the water. The maximum depth to which it grows is estimated to be 9 feet, although it does not grow to that depth in all sections of the lake in which it is present.
The coverage ofhydrilla reaching the surface during late summer of 1990 was estimated to be 300 acres, with an additional 300 acres not reaching the surface.
Although hydrilla is now established along the shallow margins of the intake canal and along the adjacent shoreline of the lake, it has not impacted Harris Plant operations.
The low velocity of water withdrawn from the canal into the Harris Plant does not pull large quantities of hydrilla (or other species of rooted vegetation) into the intake structure.
2.2 Terrestrial Monitoring Terrestrial monitoring is not required.
