• BEFORE Tile UNITED STATES NUCLEAR REGUIATORY COMMISSION In the Matter of  : Docket Nos. 50-277

PilILADELPillA ELECTRIC COMPANY  : 50-278 APPLICATION FOR AMENDMENT OF FACILITY OPERATING LICENSES DPR-44 and DPR-56 Philadelphia Electric Company, Licensee under Facility Operating Licenses DPR-44 and DPR-56 for Peach Bottom Atomic Power Station Units 2 and 3 respectively, hereby requests tha t the Environmental Technical Specifications incorporated in Appendix B of the Operating Licenses be amended by deleting Section 6.1.a.1, 6.1.a.2, and 6.3.a as indicated by the attached revised pages 14, 15 through 33 and 40.

Since initial operation of Peach Bottom Units 2 and 3 in 1974, extensive studies of fisheries, limnology and thermal e f fec t s in the Conowingo Pond have been conducted in accordance 98G011

,

,

with the technical specification requirements of these Sections

. of *'e Peach Bottom Environmental Technical Specifications. The resu' ts of the various studies have been re orted in the Semi-Annual Post-Operational Reports on the Ecology of Conowingo Pond up to and including Post-Operational Report No. 11, dated >brch, 19791! . The prin.ary purpose of the ecological studies required by the Technical Specifications was to identify any significant adverse impact on the ccology of Conowingo Pond resulting from the operation of the Peach Bottom units, with particular e.aphasis on the possible adverse impacts of chemical and thermal dischargs to the Pond. A comparison of the results reported in the various ost-operational monitoring reports with data collected since 1966, prior to operation of Peach Bottom units, shows that opera-tion of the Peach Bottom uni.ts has had no adverse effect on che ecology of Conowingo Pond.

The five-year post-operational monitoring and analytical program conducted at Peach Bottom has revealed the following facts concerning the impact of the operation of Peach Bottom Units 2 and 3 on Conowingo Pond:

1. No significant differences attributable to plant operations in total chlorophyl "a" concentrations were noted either at the surface or within the water column among the 1/ See also "A Critical Evaluation of Non-Radiological Environmental Specifications, Volume 3, Peach Bottom Units 2 and 3," preparcd by Oak Ridge National Laboratories.

.

..

different monitoring stations in the Pond; nor were there any

• significant differences in chlorophyl "a" concentrations noted between pre-operational and post-operational periods.

2. No significant differences attributable to plant operation were observed in zooplankton densities among the monitoring stations in the Pond; nor were there any significant differences nor'd between pua-operational and post-operational periods. Fluctuations in zooplankton densities appear to be attributable to natural variations, and to some extent to predation by a strong year class of gizzard shad which had been accidentally introduced into the Pond in 1972.

3. No significant differences were observed in biomass and species composition of benthos in Conowingo Pond during pre-operational and operational periods. Variations in the standing crop appeared to be attributable to natural variation.

4. There is no evidence of a reduction in the fish population caused by impingement, because small numbers of fishes were impinged. Impingement appears to be influenced primarily by river flow. Other factors having a small influence include pond elevat.on, season, and specific characteristics of the species.

5. Since the plant has no effect on zooplankton densities, the effects of entrainment are considered minimal.

The loss of adult fishes through entrainment of larvae is insignificant when compared with the exploitation rate of anglers.

6. No winter fish kills were observed due to nlant operation even though numerous unit shutdowns have occurred.

The facters that assure the protection of fishes in Conowingo Pond in relativa to the dischcrge of the plant are the preference and avoidance behavioral responses of the fishes which cause the fish to select or reject specific temperatures.

Routine power plant operation procedure also minimizes the rate of change in the plant discharge temperature.

Based upon the foregoing, Licensee has concluded that the. post-operational studies conducted pursuant to Technical Specificatienc 6.1.a.1, 6.1.a.2, and 6.3.a have confirmed that the operation of Peach Bottom Units 2 and 3 to date has not had any adverse impact on the ecology of Conowingo Pond and that continued operation of the units will not have any such impact in the future. Analysis of the post-operational monitoring data demonstrate that Peach Bottom Units 2 and 3 operations, including thermal cischarges, are not having adverse effects on primary producers, zooplankton, or benthos.

786G14

.

Although fish population densities in the discharge area have

,

varied with species, these variations are attributable to natural causes rather than plant operations. It should be noted that all thermal effcets prior to November, 1977, reflect operations with no more than three cooling towers. In November, 1977, Licensee placed in service two additional cooling towers. The availability of this additional cooling capacity during critical periods will assure further reductiins in thermal discharges to the Pond.

Accordingly, since the objectives of Technical Specification Sections 6.1.a.1, 6.1.a.2, and 6.1.a have been met and further studies are not necessary to evaluate the impacts of plant operations on Conowingo Pond, Licensee requests that these Sections and their associated Bases be deleted from the Environmencal Technical Specifications.

Pursuant to 10 CFR 170.22 " Schedule of Fees for Facility License Amendment," Philadelphia Electric Company proposes that this Application for Amendment be considered a Class III Amendment for Unit 2 and a Class I for Unit 3 since the proposed changes involved a single environmental issue which does not involve a significunt environmental hazard.

The Plant Operation Review Con aictee and the Operation and Safety Review Committee have reviewed these 166015

.

.

proposed changes to the Environuental Technical Specifications

.

and have concluded that these deletions do not involve a hnzard consideration, will not end.inger the health and safety of the public, and will not have a harmful environmental effect.

Respectfully submitted, PHILADELPHIA ELECTRIC COMPANY
