W3F1-97-0084 Page 1 of 2 WATERFORD 31996 ANNUAL ENVIRONMENTAL OPERATING REPORT This report describes implementation of the Environmental Protection Plan (EPP) for the calendar year 1996, and provides the information required by the EPP.

It should be noted that on August 27,1996 the administration of the NPDES Program was transferred from the US EPA to the Louisiana Department of Environmental Quality (LDEQ). LDEQ now has lead responsibility for all compliance and enforcement issues for Waterford 3 under the Clean Water Act with the EPA functioning in an oversight capacity.

A.

Summaries and analyses of the results of the environmental protection activities reauired " v EPP subsection 4.2:

o 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 noncompliances and the corrective actions taken to remedy them:

There were no noncompliances with the requirements of the EPP during this reporting period.

C.

A discussion of chanaes in station desian or operation. tests. or experiments made in accordance with the EPP subsection 3.1 which involved a potential sianificant unreviewed environmental cuestion:

1.

In the renewal of its current NPDES permit, Waterford 3 requested increases in the instantaneous circulating water temperature from 110 F to 114 F, daily heat limitation from 8.5 x 10' BTU /hr to 1.31 x 10' BTU /hr, and daily maximum boron limitation from 0.2 mg/l to 0.3 mg/l with respect to Entergy's plan to uprate the power output of Waterford 3. LDEQ did not grant the requested permit limit increases; however, LDEQ did approve the Waterford 3 power uprate in a letter of "No objection" as long as the current limitations and conditions in the permit are met.

2.

Based upon permission from LDEQ and US EPA Region VI, Waterford 3 SES treated its once through cooling water for zebra mussels on October 1,1996. Betz Clamtrol CT-2 was injected into the cooling water inlet and was neutralized by bentonite clay in the cooling water outlet. Composite samples, one taken before and one taken during the treatment episode,

Attechm:nt to W3F1-97-0084 Page 2 of 2 underwent static biomonitoring testing. Statistical analysis of these samples indicated nearly 100% survival for Daphia pulex and Pimephales promelas, which are the NPDES permit required test species.

Additionally, Bio-Box testing showed a 100% zebra mussel mortality rate.

D.

Nonroutine reports submitted in accordance with subsection 5.4.2:

1.

On November 17,1996, Waterford 3 notified LDEQ of periodic cooling tower spill over, which is then pumped via a level control sump pump to the stormwater ditches. The ditches are NPDES permit monitored outfalls 04A and 04B, Stormwater Runoff Effluent. In that Waterford 3 was designing system modifications to prevent this cooling tower spill over, LDEQ had no objection. Design completion and implementation is anticipated to occur during Waterford 3's next operating cycle.
