Attachment to W3F1-98-0058 Page 1 of 3 WATERFORD 31997 ANNUAL ENVIRONMENTAL OPERATING REPORT This report describes implementation of the Environmental Protection Plan (EPP) for the calendar year 1997, and provides the inform 6 tion required by the EPP.

A.

Summaries and analyses of the results of the environmental protection activities required by EPP subsection 4.2:

This section of the EPP provides protection of the two cultural resources areas on the Waterford 3 site. There were no activities which affected either the Plantation Overseer's House site or the Plantation Quarter's site, both eligible for the National Register of Historic Places, during this reporting period.

B.

EPP noncompliance's and the corrective actions taken to remedy them:

There were no noncompliance's with the requirements of the EPP during this reporting period.

C.

A discussion of changes in station design or operation, tests, or experiments made in accordance with the EPP subsection 3.1 which involved a potential significant unreviewed environmental question:

On July 23,1997, the Plant Operations Review Committee approved a new Technical Requirements Manual (TRM) Specification for the Auxiliary Boiler (AB) Fuel Oil Storage Tank (FOST). This new Specification was necessary to enable Waterford 3 to meet the ANSI N19510% fuel oil margin required for the Emergency Diesel Generators (EDGs) following the limiting design basis accident utilizing fuel in the Auxiliary Boiler FOST. This new TRM Specification ensures that the Auxiliary Boiler FOST maintains a sufficient usable volurne of fuel oil (verified by performing Surveillance Requirements) and prescribes appropriate Actions if the volume was reduced to less than required.

In order to utilize the Auxiliary Boiler FOST for this purpose, a temporary hose would be run from the FOST to the Diesel Generator fill line. This would create the potential for a diesel fuel spill, from a hose rupture, in the area around the Turbine Generator Building. An environmental evaluation determined that the Turbine Generator Building sumps and dikes are sufficient to contain the tank contents. In the event of an oil spill, Waterford 3 would

Attrchm' int to W3F1-98-0058 Page 2 of 3 implement its Spill Control and Countern asures Plan, in accordance with 40 CFR 112, which includes 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> spUi f or coverage. These measures assure that there is no adverse environ,.

' 41 consequences during day to day plant operations or adverse conditions.

D.

Nonroutine reports submitted in accordance with subsection 5.4.2:

1.

On July 8,1997, Waterford 3 notified (by telecon) the Louisiana Department of Environmental Quality (LA DEQ) that the pH limitation (upper limit of 9.0) of Outfall 01D, Steam Generator Blowdown, of NPDES Permit LA0007374 had been exceeded. In preparation for startup, the plant discharged 25,172 gallons of steam generator water I

from Outfall 01D to the Mississippi River through a mixed bed demineralizer. Prior to the release, a pH of 7.02 was measured on the demineralizer effluent. At the end of the release, the mixed bed demineralizer showed signs of exhaustion and a pH of 9.54 was measured. All other monitored parameters were within specification.

Controls were put into place such that discharges from Outfall 01D are monitored periodically to ensure that pH remains within specification.

This event was also reported in a letter dated July 10,1997, and in the NPDES Permit Discharge Monitoring Report for July 1997.

2.

On August 13, ",997, Waterford 3 notified (by telecon) the LA DEO I

that the pH in Outfall 002, Yard Oil / Water Separator, had exceeded the permit limitation (upper limit of 9.0). The discharge from the separator i

was halted immediately, and an invert lgalbn of the cause was conducted it was found that the drainage ditch that receives the flow l

from Outfall 002 had a pH of 9.3; however, the pH was 8.05 at the stormwater monitoring point, Outfall 04A, prior to leaving the plant site.

This noncompliance was attributed to the concentration of ammonia in the seal water of two recently installed condenser vacuum pumps.

These vacuum pumps are recirculating and designed to utilize no motive air (atmospheric). This design enables ammonia from the degassing of condensing turbine exhausted steam tu concentrate in the pump seal water and seal water tank. The seal water tank discharges to the Turbire Building Industrial Waste Sump which discharges to the Yard Oil / Water Separator.

Atttchment to W3F1-98-0058 Page 3 of 3 Waterford 3 has placed controls on discharges of the Yard Oil / Water Separator Sump to ensure that the pH is within specification prior to discharge. This event was also reported to the LA DEQ in a letter dated August 19,1997 and in the NPDES Permit Discharge Monitoring Report for August 1997.

3.

On September 26,1997, Waterford 3 requested (by fax) permission from the LA DEO to use Alum, as a temporary measure, to control total suspended solids in the Yard Oil / Water Separator Sump. The request was made because the suspended solids concentration was trending updward. Permission was granted by the LA DEQ on the same day.

However, Waterford 3 did not utilize the Alum because the need did not materialize.
