SECTION 1. 0 GENERAL

1.1 INTRODUCTION

This report is submitted in accordance with the Environmen-tal Technical Specifications (Appendix B to Operating Licenses DPR-70 and DPR-75) for Salem Nuclear Generating Station.* Included are the results of non-radiological environmental monitoring programs* required by the Environ-mental Technical Specifications (ETS). The reporting requirements of Appendix B to Operating License DPR-70 be-came effective on December 11, 1976, and; those of Operating License DPR-75 on August 2, 1980, when the respective units reached initial criticality.

Much of the equipment and resources utilized by Salem 1 are shared by Salem 2. Although differences in ETS reporting requirements for both units exist, no distinction is made*

for the purpose of assessing environmental impacts.

This report covers Unit 1 and Unit 2 for.the period from January 1, 1982, through December 31, 1982.

1.2

SUMMARY

  • During 1982, Salem Unit 1 generated 4,310,470 megawatt-hours of net electrical energy, while Unit 2 generated 8,307,380 megawatt-hours *.

In accordance with the requirements of Section 5 .3 of the Unit 2 ETS, all 1982 re.commended design changes were re- . i

  • I viewed for potential environmental impact. None would I

involve a change in the ETS if implemented. or. pose an un-reviewed environmental question. ~-*.

On February 22, 1982, a revision was made to Salem Generat-ing Station's NJPDES permit (NJ 0005622). This- rev is ion included limitations that were omitted from the July 15, 1981 revision and changes to numerical limits to become consistent with requirements of the modified State Certifi-cation. These revisions constituted the only change to Salem environmental permits.

No changes affecting the non-radiological portions'. of: the ETS for either unit were issued during the* 1982 calendar year; however, Amendments 51 and 18, for Units. 1 and 2, respectively, were issued on March 11, 1983. These amend-*

ments deleted ETS requirements which pertained to non-radiological water-quality-related requirements. The basis for the deletion of water quality limits. and monitoring programs is that these aquatic requirements* are* now under the jurisdiction of the U.S. Environmental Protection Agency (EPA) as established by the Federal Water Pollution Contro1 Act Amendments of 1972.

M P83 54/08-df 1-1

    • During the 1982 year, copies of monthly NPDES Discharge Monitoring Reports (DMR's) were submitted to the NRC.

Operational problems were experienced with certain systems causing discharges which exceeded permit limitations. The systems involved included the sewage treatment plant, the circulating water system, and the non-radioactive liquid waste basin. PSE&G has made a commitment to the EPA and NJDEP .to resolve the situation and has received temporary effluent limitations, through a consent order, to accommo-date the period of change. A September 30, 1983, deadline has been agreed upon for completion of modifications to the sewage treatment plant, which will ensure effluent quality consistent with the original permit. A new circulating water** system intake-discharge temperature monitoring scheme

  • must be im.plemented by November 1, 1983~ modifications to the non-radioactive waste basin are to be completed by J:une 1, 1985.

One environmentally related non-routine report was submitted to the NRC during the 1982 year. This report concerned the impingement of an Atlantic loggerhead turtle (Caretta caretta), July 10, 1982, on the circulating water system intake trash bars. As explained in the report, it is likely the turtle was dead or weakened prior to impingement.

L 3 CONCLUSION No significant environmental impacts attributable to*the operation of Salem Nuclear Generating Station Unit Nos. 1 and 2 were observed during 1982. The required biotic moni-toring (i.e., diamondback terrapin and osprey studies) was conducted in accordance with the ETS. No significant changes in* terrestrial ecology in the vicinity of the Salem Nuclear Generating Station.were observed.

SECTION 2.0 BIOTIC MONITORING AND SURVEILLANCE PROGRAMS 2.1 DIAMONDBACK TERRAPIN NESTING STUDY (ETS Section 3.1.2.1.2.l)

Northern diamondback terrapin, Malaclemys terrapin terrapin, inhabit brackish water along the Atlantic Coast from Cape Cod to Cape Hatteras. Nesting begins in* early to mid-June and continues through July. Hatching usually begins in mid-to *late August and may continue into November. Cold weather may cause the young to hibernate in or ne~r the nest and emerge the following spring (Carr, 1952; Lawler and Musick, 1972).

In 1982, diamondback terrapin activity was monitored at three beaches on the Delaware River within 4.8 km of Salem during the period May 27 through November 18. Nesting was recorded from June 3 through mid-July and evidence suggests greatest activity in mid-June and early July. The level of nesting activity varied greatly between sites but remained within the range recorded annually since 19 7 5. Number of females estimated to utilize each beach ranged fran 10 at Sunken Ship Cove to 164 at Liston Point.

In J,,982, 27 females were tagged: 12 at Liston Point and 15 at Hope Creek; none were tagged at Sunken Ship Cove. Age ranged from 9 years to well over 20 years. Five tagged turtles were recaptured in 1982; time to recapture ranged from 2 days to 5 years.

Hatching was observed to occur from mid-August through late October, and evidence of 64 hatchlings was noted.

Track evidence indicated the same predators recorded in previous years, i.e., raccoon, red fox, Norway rat, crows, gulls, and herons.

2.1.l Study Area Monitoring in 1982 was at* the same three nesting beaches as in previous years. Observations were made from May 27 through November 18 at Sunken Ship Cove and near the mouth of Hope Creek, New Jersey, and Liston Point, Delaware (Fig.

2.1-1). For a description of these locations see Volume 2 of the 1977 Annual .Environmental Operating Report.

M P83 58/5-li 2-1

2.1.2 Materials and Methods The three sites were searched during daylight hours from June through November. Weekly searches for evidence of nesting were initiated in late May. Once nesting activity was discovered, searches for nesting females, crawl tracks, and depreda ted nests were conducted three times per* week through the end of nesting in late July. Weekly searches for depredated nests and emerging hatchlings were made in August and September, semi-monthly in October, and once in November. Effort was made to minimize site disturbance and to allow females to finish nesting before being examined.

Nesting females were caught by hand, and the length and width of the carapace and plastron were measured. Each turtle was marked with an individual binary code which.con-sisted of holes drilled in"one or more of the 10 post-dorsal marginal laminae. These plates are located so as to be easily drilled with little or no injury to the turtle. A pre-numbered spaghetti tag (Floy Tag Co.) was also placed in one of the binary holes to enhance the reporting rate of recaptured turtles. Tag information is used to record turtle movements and nesting beach fidelity. For further description of the study methods see Volume 2 of the 1977 Annual Environmental Operating Report.

2.1.3 Data Reduction The following formula was developed to provide a relative estimate of the number of nesting females (N) utilizing each site:

N = (S+ ¥> D 3V where s is the number of turtles sighted, R is the number of tracks counted, D is the known number of days of nesting activity, 3 is the estimated mean number of nests laid per female during the nesting season, and V is the number of times the beach was visited over the study period.

2.1.4 Results and Discussion Nesting in 1982, as inferred fran the occurrence of crawl tracks, first occurred on June 3 at the Liston Point beach, on June 7 at Sunken Ship Cove beach, and on June 9 at Hope Creek beach. In previous years. nesting. had typicaJ,ly begun on or about June. 10. Nesting was last observed on July 12, 22, and 22 at Hope Creek, Sunken Ship Cove, and Liston Point beaches, respectively.

M P83 58/5-li 2-2

Nesting activity, also inferred from the number of crawl tracks seen at each site, varied greatly, but generally was highest in mid-June and early July (Figs. 2.1-2, 2.1-3, and 2.1-4). Nesting activity at each site continued into July, but to a lesser magnitude than recorded in June. paily and seasonal nesting activity varied greatly, but remained within the range recorded in previous years.

The annual estimate of nesting terrapins was again highest at Liston Point with 164, followed by Hope Creek with 46 and Sunken Ship Cove with 10. These estimates are, by nature of the program, conservative on the low side.

The data collected on nesting activity at Sunken Ship Cove and Hope Creek are quite sparse. The beach at Sunken Ship Cove, locally a popular fishing spot, had fishermen present on 28 percent (7 of 25 visits) of the survey dates during the nesting season in 1982. This repeated disturbance probably deterred many turtles from nesting.* Erosion and vegetative succession at the Hope Creek site in the past few years have substantially reduced the amount of open sand beach. The limited amount of open beach has made accurate counts of tracks and nests very difficult and has probably made the site less attractive to nesting turtles.

An indication of egg production at each site can be inferred from egg shell counts of depredated nests and counts of eggs fran viable nests. A total of 426 nests were recorded dur-ing 1982 and contained approximately 3,422 eggs and/or rem-nants, 88. 3 percent of whi.ch had been depredated. Liston Point had the highest egg counts with ca. 3,050 from 372 nests, followed by Hope Creek with ca. 310 fran 48 nests, and Sunken Ship Cove with.ca. 62 from 6 nests. Depredated nests, ~hich are much easier to detect than viable nests, account for 92. 5 percent of the nests at Liston Point, 60 .4 percent at Hope Creek, and 0.0 percent at Sunken Ship Cove.

Track evidence in 1982 indicated an assemblage of predators similar to previous years. At Liston Point, raccoon, Procyon lotor: red fox, Vulpes fulva: Norway rat, Rattus norvegicus: and crow, Corvus spp. were common. Raccoon and Norway rat were common at Hope Creek and Sunken Ship Cove.

Other probable hatchling predators include gulls, Larus spp:

and herons (Ardeidae).

Another fonn of egg destruction was noted at Liston Point on September 10 when a terrapin egg was observed to have been pierced by a rhizome fran saltmeadow cordgrass, Spartina patens. This is the first observation of this phenanenon

.. M P83 58/5-li 2-3

over the course of the present study, so this does not appear to be a significant mortality factor for terrapin eggs.

Hatchling depredation was noted at the Hope Creek site on August 13 and 31 when the remains of 3 recently.hatched ter-

~ rap ins were found. It is likely, due to the nature of the bite marks, that Norway rat was the primary predator.

A total of 27 terrapins were tagged during 1982: 12 at Listqn Point and 15 at Hope Creek; none were tagged at Sunken Ship Cove. Five . tagged turtles were recaptured in 1982, all at Hope Creek, which was the initial site of tagging. The recapture interval ranged fran 2 days to five years for four of the turtles, while orie had lost its tag.

The turtle recaptured after five years had increased 2

  • percent in carapace length, from 16.4 cm to 16.7 cm.

Mean size of females captured at Liston Point and Hope Creek was very similar. Mean carapace length and width was 17.8 cm and 14.3 cm, respectively, at Liston Point, and 17.2 cm

. and 14. 0 cm at Hope Creek. Mean plastron .length and width was 15.9 cm and 9.4 cm, respectively, at Liston Point, and 15.3 cm and 9.1 cm at Hope Creek.

The youngest female captured on a nesting beach was approxi-mately 9 years old; the oldest appe.ared well in excess of 20 years. Exact age determination of older specimens is diffi-cult since the ridged annuli on the carapace scu tes become less distinct *with age. Eventually, the shell becomes com-pletely smooth, which may indicate age to perhaps 40+ years (Hildebrand, 1932)

  • A total of 64 sets of hatchling tracks were noted from August 13 to September 23: 6 at Sunken Ship Cove, 1 at Hope Creek, and 57 at Liston Point. Incubation period for six marked nests ranged from 60 to 99 . days and averaged 71 days *.

2.2 OSPREY AND BALD EAGLE SURVEY (ETS Section 3.1.2.1.2.2)

The study objectives are to record the occurrence of osprey and bald eagle and to monitor nesting of osprey in the vicinity of Artificial Island. The North American osprey, Pandion haliaetus carolinensis, had been classified as "status undetermined" (USDI, 1973) but has since been deleted from the federal list; it is still considered endan-gered *by the State of New Jersey ( NJDEP, 1979). The south-ern bald.eagle, Haliaeetus l* leucocephalus, is federally classified as "endangered" (USDI, 1979).

M P83 58/5-li 2-4

Osprey were observed in the study area from April 21 through September*10. Eleven nests were occupied, 4 of which fledged 5 young.

Bald eagles were sighted . in the study area on two dates dur-

These sightings re.present 2 individuals.

~ ,, -

2.2.1 Study Atea -

The study area extends 16.1 km north, 12.9 km south, and 8.0 km east and west from Salem. The northern boundary is near Finns Point, New Jersey, and the southern bou.ndary is just north of Woodland Beach, Delaware (Fig. 2.1-1).-

The area features bay, riverine, marsh, upland field, and wooded habitats. Pilings, range towers, and powerline towers are cormnon.

2.2.2 Materials and Methods Known osprey nests. were surveyed by helicopter once in March and April, twice* in June, and once. in July and Aug:ust; no

..*. flight was made in May. During flights the area was sur-veyed for any new osprey nesting sites and bald eagle sight-

. ings.. The- number of adults and young in each nest was recorded. To avoid undue stress on the birds, the helicop-ter remained at a di.stance ( > 50 yds) . from the nest and paused only briefly to allow the nest to -be viewed with

.binoculars.

  • Sightings of osprey and bald eagle were also recorded in the course of other field work and are included her_e *.

2~2.3 Results and Discussion In 1982, osprey were sighted in the area from April 21 through September 10, typically on or near nesting struc-

. tures. The number of adult-sigh tings was greatest in June

( n=l8) and decreased through September ( n=2).

Fourteen* nests were located; 11 were occupied and appeared active, while* the remainder may have- been constructed as housekeeping nests by sexually immature birds or as second-arT nests by adjacent breeding adults *.

M' P83 58/5-li 2-5

Of the 11 occupied nests, it is estimated that 4 were successful and fledged* 5 young. This compares with 6 fledged in 1981 and 7 fledged in 1980. Though local production has continued to decline in recent years, the number of birds and nests in the area has remained high, an indication that the population near Salem continues to be active.

Bald eagles were sighted in the Delaware portion of the study area on two dates during

  • 1982. On June 24 an immature bald eagle was spotted perched in the top of a large cedar tree just south of the Smyrna River Jetty. A second bald eagle, in adult plumage, was spotted in the same area on August 19 flying over the marsh.
