1.0 INTRODUCTION

This 1988 Annual Environmental Operating Report (AEOR) for the Hope Creek Generating Station was prepared in accordance with Subsection 5.4.1 of Appendix B to Facility Operating License No. NPF-57, Environmental Protection Plan (Nonradiological). The reporting requirements of the Environmental Protection Plan (EPP) became effective April 11, 1986, with the issuance of the initial Hope Creek operating license. This is the third AEOR submitted for Hope Creek Generating Station. It corresponds to the reporting period January 1, 1988 to December 31, 1988. Hope Creek Generating Station produced 6,985,745 megawatt-hours of net electrical energy during this period.

As required by Subsection 5.4.1 of the EPP, we have included summaries and analyses of the results of all required environmental protection activities. This information is described in section 2.0. Section 3.0 addresses the issue  !

of EPP compliance. Changes to station design or operation and the involvement of potentially significant unreviewed environmental questions are addressed in Section 4.0.

Unusual and/or important environmental events are discussed in Section 5.0. Supplemental information relating to the review of proposed changes in station design and operation as discussed in Section 4.0 has been included as an appendix to this AEOR.

2.0 ENVIRONMENTAL PROTECTION ACTIVITIES 2.1 Aquatic Monitoring Subsection 4.2.1 of the EPP references the Clean Water Act as the mechanism for protecting aquatic biota through water quality monitoring. The.NRC relies upon the State of New Jersey, acting under the authority of the' Clean Water Act, to ensure applicable requirements for aquatic monitoring are implemented.

The State of New Jersey requires as part of their NJPDES permit program that effluent monitoring be-performed, with the results summarized and submitted monthly on discharge monitoring report forms (DMR's).

The monitoring-is intended to determine compliance with permit (NJPDES No. NJ0025411) effluent limitations. We have reviewed the DMR's corresponding to the AEOR reporting period and have determined that no significant deviations have occurred. We have observed no evidence ci trends toward irreversible damage to the environment. Copies of DMR's are available upon request..

As discussed in the 1987 AEOR, PSE&G obtained construction approvals for a new sewage treatment plant at Hope Creek Generating Station during 1987 and construction of the new treatment plant continued through most of 1988. The new plant is still undergoing startup testing. The existing sewage treatment plant at Hope Creek continues to be available in a standby mode to ensure accsptable effluent quality.

s a 2.2 Terrestrial Monitoring The primary potential effect of station operation on terrestrial resources derives from cooling tower drift.

Subsection 4.2.2 of the EPP requires that a " Salt Drift Monitoring Program" be implemented to measure drift rate and deposition on native vegetation, and to assess the impacts of cooling tower salt drift on the environment in the Hope Creek Generating Station vicinity.

l PSE&G initiated a salt drift monitoring program in August 1984 according to the Nuclear Regulatory Commission approved study plan. The goal of the study program was to collect preoperational and operational data on salt deposition and on sodium chloride (Nacl) concentrations in vegetation and soils in the vicinity of the Hope Creek Generating Station.

A report summarizing the first year of operational data collection was submitted to the NRC as an appendi:: to the 1987 AEOR. Operational phase data collection continued throughout 1988 and was completed in early April 1989.

Because the operational phase data collection was scheduled for completion in early 1989 and the operational phase summary report will include a detailed analyses of the 1988 data, there is no 1988 annual monitoring report as referenced in Section 4.2.2 of the EPP. Preparation of the

" Operational Summary Report for the Hope Creek Salt Drift Monitoring Program" will be completed in June 1989 and submitted to the NRC when finalized.

The operational summary report will include analyses of the i data for seasonal and spatial trends as well as correlations '

with meteorological data. In all three studies (salt deposition, native vegetation, and surface soils), no ,

obvious trends in salt deposition or concentration either by l site or by season are apparent in the operational data.

Variability of the data most likely masks any potential differences by season or site.

%' . i 3.0 EPP COMPLIANCE STATUS t

~ Subsection 5.4.1 of the EPP requires: a) a list of EPP noncompliance and.the corrective actions taken to remedy them, b) a list of all changes in station design or operation which involved a potentially significant unreviewed environmental question, and c) a list of nonroutine reports submitted in accordance with Section 5.4.2 of the EPP. PSE&G continued to operate Hope Creek Generating Station in compliance with the EPP during 1988 and had no instances of noncompliance that required corrective actions. Changes in station design or operation and nonroutine reports are addressed in the following two sections of this annual report.

4.0 CHANGES IN STATION DESIGN OR OPERATION Pursuant to the requirements of Section 3.1 of the EPP,

-PSE&G reviewed all changes in station design or operation proposed during 1988 for potential environmental impact and none of the changes involved an unreviewed environmental question or constitute a decrease in the effectiveness of the EPP in protecting environmental values. Most of the changes involved minor modifications to facility components and none involved a significant change in effluents. As discussed below, the only change in station operation with a potential to significantly affect the environment was a modification to the Hope Creek service water" intake that changed the frequency of traveling screen rotation.

As early tus October 1986, Hope Creek Generating Station proposed modifying the service water intake traveling screen controls to permit intermittent operation as needed based on differential pressure across the screen panels. To minimize impingement mortality, the service water traveling screens had been configured during construction for continuous rotation. However, it became apparent during startup and lower power testing that continuous operation was contributing to premature mechanical failure of screen components and requiring unscheduled outages of the traveling screens for continual maintenance.

-4 -

s- i In November 1986, PSE&G prepared an environmental evaluation ,

of the potential impact of modifying the traveling screens  ;

for intermittent rotation based on the three months of 4

impingement data that were available at that time. This  !

environmental evaluation concluded that the additional impingement mortality that would result from intermittent screen rotation would not constitute a significant environmental impact and would not be an unreviewed environmental question.

To further evaluate the potential environmental effects of the Hope Creek service water intake and to improve the previously estimated impingement rates, PSE&G continued to sample impingement by the traveling screens through September 1987. As further support that intermittent rotation is not a significant environmental impact, PSE&G reassessed the potential environmental impact of intermittent screen rotation using the improved estimated impingement rates resulting from the more extensive database. This evaluation entitled, " Environmental Evaluation of Intermittent Operation of the Hope Creek Service Water Intake Traveling Screens," has been included as an appendix to this AEOR.

Modifications to the Hope Creek service water intake traveling screens that changed the mode of operation to an intermittent basis were implemented in October 1988. The modifications were completed and the work' orders closed by November 21, .1988. As a result of these modifications, the need for unscheduled maintenance outages of the equipment has been reduced and reliability of the traveling screens has been greatly improved.

l 5.O NONROUTINE REPORTS Subsection 5.4.1 of the EPP requires that a list of all nonroutine reports (submitted in accordance with Subsection 5.4.2) be included as part of the AEOR. Hope Creek Generating Station experienced no unusual or important events that indicated or could have'resulted in "significant-environmental impact" during the 1988 reporting period.

Consequently, there were no nonroutine reports submitted to the NRC.

Introduction Impingement impacts of the Hope Creek service water intake were evaluated in both the Hope Creek Generating Station (HOGS)

Environmental Report - Operating License Stage (OLER) and the Final Environmental Report (FES) with similar conclusions. In the FES, the potential impingement at Hope Creek was compared to actual data from the Salem impingement studies and it was estimated that impingement impacts at Hope Creek could be 10 percent or less of the impacts currently experienced at the Salem circulating water intake. 'Ihe U.S. Nuclear Regulatory Cammission thus concluded that impingement of organisms due to operation of Hope Creek should not significantly impact important fishery populations. These conclusions assumed a 50 percent survival rate of impinged fish due to the installation of a " fish rescue system", referring to continuously rotated Ristroph travelling screens.

'Ihe OIER equated Hope Creek impingement losses with the 1977 Salem service water estimates which ranged fram near zero to approximately 25,000 fish per month. As stated in the OI.ER, there are several key elements in the design of the HOGS intake whicn minimize impingement losses regardless of screen rotation: 1) closed cycle cooling with low water makeup requirements,1) low intaks velocities through the trash racks, and 3) location of the intake ntructure parallel to arri nearly flush with the shoreline.

Closed cycle cooling can be considered the best available technology for minimizing cooling system impacts. By reducing the volume of water withdrawn and the intake velocities, Hope Creek has 2ninimized impingement loses to a level deemed insignificant to the estuary populations of the species present.

l 1 r l

Material & Methods To more fully evaluate' impingement loses at the HC service water intake, PSE&G collected impingement data at the HC intake frun April 1986 through September 1987. During this period samples were collected on a continuous basis to estimate total impingement during one twelve hour period per week. 'Ihese data were then extrapolated utilizing the methodology described below to estimate the number of each species impinged on an annual basis (Table 1).

An estimate of the annual utznber of fish impinged was calculated using a three step computational method. The first step was to

'obtain an estimated weekly density from the sample data by calculating a mid-point average of two consecutive daily estimates as follows:

Dn + bl

g. -

2 where:

Og = mean weekly density Dn = density during the n th collection period.

Fran this number the estimated number impinged for the week was calculated by using the following formula:

Iy =D n xPxT I y= weekly number impinged Dn = weekly impingement density P = service water punp capacity T = duration of pump operation during week

'Ihe estimated annual number impinged was then calculated by summing the weekly estimates.

, - a r .*

Evaluation Based on the 1986-1987 data, it is estimated that a total of 192,600 fish and 163,000 blue crab may be impinged annually by the Hope Creek intake (Table 1). While the numbers of blue crab are large, their well documented high survival rate reduces concern for this species as actual losses are minimal. 'Ihe six most aburriant fish species, comprisirg more than 92 percent of the total were; Atlantic croaker (57.4%), bay anchovy (13.6%),

naked goby (10.5%), weakfish (4.8%), hogchoker (4.3%), and white perch (2.3%) . Table 2 and Figure 1 compare the estimated Hope Creek impingement loses of these fish species with the 1978 SGS service water data. Generally, HC numbers are greater because of the different screen design at HC and because of annual variation in fish abundance. Even though the HC service water system and the Salem service water system are volumetrically similar, the smaller screen mesh size used at HC effectively lowers the minimum impingeable size range and increases tha number of fish vulnerable to impingement. Annual variation in fish abundance, particularly as it pertains to Atlantic croaker, also explains the large difference in estimated losses. During the winter of 1986-1987, Atlantic croaker abundance was markedly higher than it had been in recent years as indicated by river trawl data collected during 1984 through 1988 (PSE&G 1c84, 1985, 1986, 1987, 1988), and may not reflect a typical annual estimate of losses.

Previously, the impact of the HC service water system was deemed insignificant to estuary populations because the projected impingement losses would be no greater than 10% of those recorded at the Salem circulating water intake. A cnaparison of the projected HC impingezaent losses with Salem ciro.11ating water impingement estimates from the Salem 316(b) Demonstration for the four species for which there is common data, indicate that the BC service water losses remain well below the 10 percent previously cited.

l, .L ..,

Conclusions Based on the environmental-evaluation of the estimated impingement rates at Hope Creek, and on previous agency determinations, the potential impingement impacts of the Hope Creek intake on Delaware Bay fisheries are not significant.

'1hese conclusions hold true regardless of scrern rotation.

PSE&G's review of the potential impingement impacts utilizing 1986-1987 data support the previous conclusions of the OIER and the FES. 'Ihe data show that although the Hope Creek intake may inpinge more fish than the Salem service water intake, the number is considerably less than the 10% of the Salem citu11ating water system impingement total, which is not considered to have any significant impact. Changing the traveling screen rotation schedule to an intermittent basis and amnnig 100% mortality will not affect these conclusions.
