.e Introduction-This:1987 Environmental Operating Peport for the North Anna Power Station -

'is subnitted by the Virginia Electric and Power Capany _ as required under

. Section. 5.4.1 of Apperxlix B, Environmental Protection Plan (EPP). The objec-

tives of the. EPP are ' to verify that the power station is operated in an environmentally acceptable' manner; to coordinate NRC requirenents and maintain consistency with other federal, state and local requirsents; and to keep NPC infonned of the environmental effects' of facility construction and operation.

During 1987, no significant adverse environmental inpact occurred as a result of the operation of North Anna Power Station, Units 1 and 2.

Aquatic issues are addressed in the licensee's NPDES permit nunber VA 0052451 issued by the Virginia State Water Control Board, and the NPC relies on this agency for regulation of natters involving water quality and aquatic biota. Listed below are the suntnaries and reports as required under Section 5.4.1 of the EPP.

Plant Desian and Operation (Section 3.1)

Construction was ccr.pleted in 1987 of a snall (maxinum capacity 992 kw) hydroelectric facility at the main dam of Iake Anna, the cooling rmrvoir for North Anna Power Station. This facility is presently in operation and being monitored for fish passage by Virginia Pomr in cooperation with the U.S. Fish and Wildlife Service.

A report of the results of this study will be subnitted to the Fish and Wildlife Service this fall.

8erbicide Application: Corridor Richts-of-Way (Section 4.2.1)

' The herbicide, Spike SG, was used' for brush control around Corten tower -

foundations on-the North Anna-Iouisa, North Anna-Morrisville, and North Anna-Ladysmith 500 kV lines during 1987. No herbicides were used for brash control on the North Anna-Midlothian 500 kV line during 1987.

Erosion Control Inspection (Section 4.2.2)

Erosion inspection on right of way was made on the North Anna-Midlothian, North Anna-Morrisville, North Anna-Louisa, and North Anna-Ladysmith 500 kV lines on July 23 and 24, 1987.

Iocations were recorded where erosion was taking place on the North Anna-Morrisville, North Anna-Midlothian, North Anna-Iouisa and the North Anna-Iadysmith lines. Most of these locations noted were caused by vehicle travel up and down the rignt of way.

These areas wre disced, fertilized, seeded, and mulched with additional straw bales bells installed to prevent erosion.

Station Site In 1987 an on-site erosion control ingection was performed at North Anna Power Station by the Surveillance and 'Ibst Engineering Department on October 16, 1987, through October 23, 1987, according to Periodic Test Procedure 1-PT-9.3.

'Ihe frequency for performing 1-PT-9.3 was changed in 1987 frcm every four months to every twelve months.

This change is supported by the 12/30/80 I

l revision of the North Anna Power Station Environmental Protection Plan, which l

states that site erosion inspection shall be conducted at twelve month inter-l vals as a minimum (Section 4.2.2).

In addition, Pegulatory Guide 1.127 I

i-reccmrends that erosion control inspections should be perfctmed at one year intervals for the four years after the reservoir water attains nonnal level, and at longer intervals after the four years have elapsed.

During tits erosion : control inspection for 1-P1'-9.3, minor erosion-was noticed next to the. security _ fence on the outside of the protected area on the service water ' reservoir side. ' Minor erosion also existed on L the lakeside slopd of Parking lot C.

Corrective action is not required for these areas at this time due to the ndnimal amount of erosion.

During the October erosion control inspection, vegetation was noted and then removed frcra the slope west of the Unit 1~ and 2 Intake Structure.

Pepairs to Dike VI were made due to erosion located on the dcwnstream side of Dike' VI at the west end of the dike. These repairs were cmpleted in December of 1987.

Erosion was found underneath the railroad track near the SCOB-N Building.

Work will be performed in the near future to fill this eroded area.

Another severely eroded area on the slope near the servi water valve house between the csnergency dike and the service water dike was noted.

'Ihe l

work to fill in this severely ertded area will be included in the Service Water Capital Inprovment Project.

Nonccmpliances (Section 5.4.1)

There were no Environmental Protection Plan nonecnpliances reported during 1987.

Dear Mr. Kregloe:

North Anna Power Station - 011 Spill This letter provides confirmation of an earlier report of an' ail spill at North Anna Power Station.

The spill occurrea on Saturday, October 31, 1997, and was reported to your office by telephone at approximately 1930.

At 1730 on October 31, station watch personnel noticed a sheen of oil of approximately 3 square feet on the surface af the discharge canal in the vicinity of Outfall 004.

and oil adsorbent pads were used to remove the shran from the wat An investigation into the cause of the spill could not identify the source as any of the turbine building sumps or any of the outside storm drain entrances.

It was verified that no oil entered North Anna lake as none was found beyond the perman'ently deployed boom at the end of the discharge canal. No adverse environmental impact was observed.

Since the source of the oil could not be identified, no specific corrective action was specified.

Dear Mr. Kregloe:

Re:

North Anna Power Station - Discharge of Powdex Resin This letter confirms our earlier report of an unusual discharge et our North Anna Power Station.

The discharge occurred and was reported to you on October 16, 1987.

On that day, a slurry of Powdex resin, a ground bead of polystyrene, and water used to polish condensate water, was being prepared in a holding tank prior ~to pumping into the polishing vessel.

An outlet valve open co suction of the vessel pump failed closed causing the holding tank to fill and overflow.

The overflow entered the floor sump which happened to be pumping to Outfall tne time.

Before sump pump operation could be halted, apprcximately 2 cu ft of resin slurry was discharged to the discharge canal.

heavier than wate and no cleanup was effected.

The resin is slightly Replacement parts have been ordered for the valve and repair will take place as soon as possible.

Until that time alternate arrangements will be made that prevent che tank from overflowing.

Polystyrene resin is chemirally inert and no environmental impact was observed or should be expected.

If you have any questions or desire additional information, please contact this office.

Dear Mr. Kregloe:

North Anna Pcwer Station - Oil Spill This letter confirms the report of an oil spill made to Mr. Dave Chance in your office on September 26, 1987.

The report was made at 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br />.

At 1830 hours0.0212 days <br />0.508 hours <br />0.00303 weeks <br />6.96315e-4 months <br /> on September 26 station personnel observed a sheen of oil approximately 2 ft x 20 ft on the surface of the discharge canal near the discharge of a stonn drain close to Outfall 004.

There is a permanently deployed boom at that loca* ion but the sheen was partially escaping the boom at one end where it had pt,lled away from its mooring.

Absorbant pads were immediately placed in the breech and at the stonn drain discharge.

The source of the oil was found to be a crane parked in the alleyway between the turbine building and containment. A small amount of oil was found to be dripping from the crane boom and entering the storm drain located in the alleyway.

Absorbant pads were placed under the crane and the leak was stopped.

i All visible oil on the water's surface was removed and inspection of the i

permanent boom at the end of the discharge canal indicated that no oil entered l

1.ake Anna.

No environmental impact resulting from this spill was observed.

Personnel have been cautioned to take more care when using heavy equipment near a storm drain.

Dear Mr. Kregloe:

Re: NORTH ANNA POWLR STATION - REPORT OF OIL SPILL This letter confirms the earlier report of an oil spill that occurred at the new hydroelectric turbines down river from North Anna Power Station on September 8, 1987. The incident was reported to Mr. Larry Carpenter of your office at 1300 hours0.015 days <br />0.361 hours <br />0.00215 weeks <br />4.9465e-4 months <br />.

On the morning of September 8,1987, station personnel observed a 10ft x 20ft oil sheen on the Ncrth Anna River below the dam.

Heavy rains occurring at the time quickly dispersea the sheen so that no cleanup was possible.

Unknown to personnel, some hydraulic fluid had apparently collected out of view under a housing on the turbine platform during a recent maintenance operation. The heavy rains unfortunately washed this hydraulic fluid into the river. No oil was deposited along shorelines, however, and no adverse environmental impact was observed.

Investigation of the incident revealed that design of the hydraulic system does not allow complete drainage of the system and that some fluid can accumulate on the platform. A way is being sought during this shakedown period for the new units to eliminate the problem or to be able to recover the oil so that a rainfall event does not precipitate another oil spill.

Dear Mr. Kregloe:

North Anna Power Station - Oil Spill This letter confirms our previous telephone notification to the Virginia Water Control Board of a release of oil from North Anna Power Station to the plant's waste heat treatment facility.

At approximately 5:00 p.m. on April 4, 1987, unusually high condensate water flow left the station via the turbine sump system and entered the station's discharge canal.

This flow caused the containment boom at the catch basin placed oil soak. pads to be released. discharge to break loose and allowed a sm Station personnel estimate the volume of oil to be one quart or less.

The second containment boom across the end of the discharge canal collected some,and possibly all, of the released c:1 and pads.

As corrective action, station personnel removed the collected oil and pads contained by the second boom. The first boom was resecured. Station personnel reported no adverse environmental impact observed as a result of this oil spill including no observed damage to wetlands, shorelines, public or private wa.ter or wildlife.

If any questions arise as a result of this incident, please do not hesitate to contact us.

Dear Mr. Kregloe:

North Anna power Station - Report of Oil Spill This letter confirms our earlier report of an oil spill that occurred at North Anna on February 22, 1987. The incident was reported to your office at 1628 hours0.0188 days <br />0.452 hours <br />0.00269 weeks <br />6.19454e-4 months <br />.

At 1505 hours0.0174 days <br />0.418 hours <br />0.00249 weeks <br />5.726525e-4 months <br />, station personnel observed a sheen of oil approximately 20 x 40 feet on the surface of the discharge canal in the area of the oil water separator (0utfall 004).

Oil sorbent pads were laid down innediately to absorb the oil and a permanently deployed boom in the area was repositioned to contain the sheen.

None of the oil reached Lake Anna and no adverse environmental impact was observed.

A series of events apparently contributed to the oil spill that occurred.

Water being decanted from a resin phase separator was inadvertently drawn down to a level that allowed some of the resin to drain to the turbine buildi g n

sump. When Unit II turbine experienced leaks the sumps filled and had to be pumped to the oil water separator.

The resin fines do not settle completely and they tend to adsorb oil. Thus when the oil water separator discharged, the fines carried over a small amount of oil.

In the future, a close accounting of the resin level in the separator will be kept so that the drawn down will not allow resin to be decanted.

e If you have any questions or desire additional information, please contact this office.
