SALEM NUCLEAR GENERATING STATION ENVIRONMENTAL TECHNICAL SPECIFICATIONS JUSTIFICATION FOR PROPOSED CHANGE ETS Section 2.1.la Maximum Delta T Across Condenser During Normal Operation ETS Section 2.1.lb Maximum Delta T Across Condenser During Pump Outage ETS Section 2.1.2 Maximum Discharge Temperature Throughout the latter portion of 1977, Salem Nuclear Generating Station Unit No. 1 experienced difficulty complying with Environmental Technical Specification Section 2.1.la which limits the maximum temperature increase (delta T) across the circulating water system (CWS) condenser to 16.5°F when all six circulating water pumps are in service.
This was attributed, in part, to the non-representative locations of both the temperature sensors (RTD's) associated with the station computer and local thermomete~s.
(See the related portions of NRC Combined Inspection Report 50-272/78-04 and 50-311/78-04 dated March 23, 1978 and the licensee's response dated April 14, 1978).
As indicated in our April 24 response, a design change has been implemented which properly relocated the RTD's to a point where the temperature recorded is more representative of the average condenser outlet flow in each of the six water circuits.
A test was run in which six outlet locations were measured sumul-taneously during a period of high (1100 MWe or more) reactor power level.
It was observed that the average delta T exceeded the ETS limit (16.50F) on several occasions despite relatively clean condensers and steady, 6-pump operation (Figure 1).
Operation in 1978 subsequent to the RTD relocation has demonstrated continued delta T measurements near 16.5°F at times.
It is apparent to the Licensee that under normal operating conditions, if the delta T exceeds 16.soF, corrective actions available are limited.
The present ETS limit is likely to force load reductions on a frequent basis.
To avoid load re-ductions and increase the availability of the station at full rated output, the Licensee needs the flexibility to operate at a delta T of up to 18.SOF and a maximum condenser outlet temperature of l060F when all six CWS pumps are in service.
With respect to system range and accuracy, a 320F -
1500F range was requested and justified in LCR 78-06.
PSE&G has recently reviewed system accuracy and finds that +1.soF is more representative of the equipment in service and of equipment under consideration for future use.
DEC:fmc 3/9/79 MP79 4 31
The ecological impacts associated with the thermal component of the CWS discharge from Salem Station under baseload conditions have been descriped in three documents (IA, 1974; IA 1975, PSE&G, 1978).
These documents were prepared as part of a 316(a) Demonstration, Type III, for the U.S.
Environmental Protection Agency in support of alternative thermal discharge limitations.
We concluded iQ these documents that the once-through cooling system currently in use would have a minimal impact on the ecology of the Delaware River.
The Licensee now also concludes that the proposed increase in the overall temperature rise across the CWS condenser from 16.5 to 18.5°F will not degrade the quality of the Delaware River Estuary in the vicinity of Artificial Island.
The following areas of impact were assessed for the current operating conditions and are revised below to reflect the proposed ETS change:
1 - Nursery Areas:
effect of the plume on juvenile fishes near Artificial Island.
2 -
Plume Entrainment:
secondary entrainment effects *on major ichthyoplankters and macrozoo~lankters that occur
- near Artificial Island.
3 - Migration of Anadromous Fishes:
effect of the '
thermal plume on the migratory behavior of anadromous fishes which occur in the Delaware River.
Nursery Areas Experimental studies based on current operating conditions have quantified the portion of nursery habitat potentially removed by the Salem plume for alewife, Alosa pseudoharengus; Atlantic menhaden, Brevoortia tyrannus; bay anchovy, Anchoa mitchilli; Atlantic silverside, Menidia menidia; white perch, Morone americana; striped bass, Marone saxatilis; weakfish, Cynoscion regalis; spot, Leiostomus xanthurus; and hogchoker, Trinectes maculatus.
Experimental results demonstrate that Atlantic menhaden, weak-f1sh, spot, and bay anchovy will avoid the portion of the plume 4°F or more above ambient only during the warmest period of the year (Table 1).
This area represents, at most, 5.3% of the estimated total volume of the river segment 5,000 ft north and south of.the discharge, the maximum extent of the 2.25°F is9therm (Table 2) under the proposed conditions.
All other P78 25 26
species tegted showed no avoidance response until temperatures reached or exceeded delta 8°F.
It is probable that the region of the plume within the 9°F isotherm.will be physically denied to fishes, under the proposed condition, regardless of tempera-ture, since velocities encountered will exceed their maximum sustained swim speed.
The area within the 8°F isotherm was denied under the base condition.
Maximum sustained swim speed for the size classes of the species considered is 1.5 fps (Tathum, 1971).
Velocities "within the maximum penetrable plume delta temperature (9°F) range from 1.5 fps to a maximum of 10 fps at the point of discharge (ARL, 1977).
The temperature of the Salem plume during the proposed operat-ing condition is not expected to have a detrimental effect on nursery areas in the vicinity of the station.
The impact of the thermal discharge will be limited primarily to the removal of habit at which is not unique and which is presently utilized marginally and infrequently by relatively few species.
Plume Entrainment The effect of plume (secondary) entrainment on the important ichthyoplankton and macrozooplankton that occur near Artificial Island have been estimated for the base condition, for the following: bay anchovy eggs and larvae, Anchoa mitchilli; white perch larvae~ Morone americana; weakfish larvae, Cynoscion r_egalis; and the invertebrates Gammarus spp.
and Neomysis americana.
The potential effect of secondary entrainment is related to both entrainment rate and exposure time.
During operation under the proposed change, the maximum temperature increase (delta T) is 18.5°F (l0.3°c) at the point of discharge.
A relatively small portion of the water mass passing the station and of the organisms contained within it will be exposed to elevated temperatures.
When two units are operating (l,040,000 gpm/unit) less than 8.0% of the average tidal flow, 450,000 cfs (USAE, 1959) will be affected by the plume (Table 3).
Of this portion, approximately 57% will be heated by less than 4.75°F (2.6°c) which is within the normal daily ambient water temperature range.
Exposure time will be greatest during slack tide (current velocity o.o-o.s fps) which occurs for approxi-mately 17 minutes between flood and ebb.
During running tides ambient current minimizes extent and effect of exposure.
Exposure time is further reduced with depth as a result of smaller plume volumes (ARL, 1977).
No significant mortality or reduction of populations of the major components of the plankton community is expected because of secondary entrainment.
Ecological data indicate that the species utilizing of the region near Artificial Island is not P78 25 27
~-----*----.....,---~---*-* ---- ------------~-----*----~-----
,I limited to or especially associated with the area of the thermal plume.
Less than 8.0% of the tidal flow past the station is expected to be secondarily entrained and of this, only a small fraction will be heated to a biologically detrimental degree.
~
Migration of Anadromous Fishes Plume characteristics have been evaluated relative to temperature avoidance responses of anadromous fishes which occur in the Delaware River and the characteristics of the thermal plume.
An estimate -of -the size of the segment which might be avoided during migration has been presented for the proposed condition (Table 4).
Ecological studies in the region of Artificial Island have established that five anadromous fishes utilize the Delaware River as a migratory pathway to and from upriver spawning areas; these are:
blueback herring, Alosa aestivalis; alewife, Alosa pseudoharengus; hickory shad, Alosa mediocris; American shad, Alosa sapidissima; and striped bass, Marone saxatalis.
All available data on fish migration, avoidance temperatures, and the thermal plume configuration duririg the base operating condition (delta T of 16.5°F) and the proposed condition (delta 18.5°F discharge) indicate that-anadromous fish movement will be neither impeded nor limited by the thermal plume.
Anadromous fishes utilize the entire river width in passage through the Artificial Island area.
They may avoid the highest temperatures near the discharge jet but are expected to readily pass around and/or under this relatively small area (Table 4).
- The maximum temperature increase of the plume outside the discha_rge jet under this condition is 9°F (5°C)
(ARL, 1977).
Table 5 shows this to represent some 10% of the river cross section when ambient current is 0.5 fps and 3% of the river cross section ambient current is 2.5 fps.
No thermal blockage of the river is expected.
No reduction in numbers of adults reaching spawning areas is expected.
Juvenile emigration will not be adversely affected.
Consequently, no depletion of anadromous fish stocks can be expected as a result of the pro-posed change.

SALEM NUCLEAR GENERATING STATION ENVIRONMENTAL TECHNICAL SPECIFICATIONS JUSTIFICATION FOR PROPOSED CHANGE ETS SECTION 2.2.l BIOCIDES These proposed changes incorporate the changes proposed in LCR 77-12, December 21, 1977, and *add changes to facilitate compliance while making the Environmental Technical Specifications consistent with NPDES Permit NJ 0005622.
The licensee agrees to maintain a free available chlorine residual below 0.1 mg/l in the circulating water as discharged to the receiving stream.
Service water is discharged into the circulating water system prior to the proposed monitoring point.
Consequently, this proposed moni taring me.thod will satisfy the objectives of NPDES permit* compliance and detection of any chlorine residuals discharged to the environment higher than 41t were anticipated in the Final Environmental Statement.
DEC:kd
2.2 2.2.1 CHEMICAL BIOCIDES Objective To insure that the chlorine res*idual released from the Circulating Water and Service Water Systems is controlled and will not have an adverse effect on the natural aquatic environ-ment of the receiving waters.
Specification
- 1.
The concentration of free available chlorine produced by chlorinating the Circulating Water System and Service Water System shall not be greater than 0.1 mg/liter where the circulating wo.ter discharge enters the receiving stream.
If this specification is exceeded, the chlorine addition rate shall be reduced as necessary to operate within the specification.
- 2.
Circulating Water and Service Water pump intakes shall not be chlorinated more than 3 times per day.
Chlorination periods shall not exceed thirty minutes.
Chlorination of more than 3 Circulating Water pump intakes at one time shall not be permitted.
2.2-1
Monitoring Requirement One circulating water discharge associated with Unit 1 and one circulating water discharge associated with Unit 2 shall be continuously monitored for free available chlorine residual during treatment.
The continuous monitoring (during treatment} shall be per-formed using a free chlorine residual analyzer equipped with a strip chart recorder.
The chlorine monitors shall be calib~ated once per month when the chlorination system is in service with an amperometric titrator using ASTM Methods D-l253 and D-l427.*
It the chlorine monitors are inoperable,. f:ree available chlorine residual shall be det~rmined by manual analysis of a grab
- sample taken at the same location during the chlorination cycle.
- For a discussion of precision and accuracy obtainable through amperometric titration, see Standard Methods, l4th edition, pp. 310-313.
2.2-2 1
Bases The Water Quality Certificate issued by the Delaware River Basin Conunission for Salem Nuclear Generating Station limits the free chlorine residual in circulating water discharged from the plant to maximum of 0.1 mg/liter.
This also conforms to EPA-NPDES requirements of 0.2 to 0.5 mg/liter.
Intermittent treatment of cooling circuits in fresh and brackish water environments with a biocide (chlorine, sodium hypochlorite) is a reliable method for maintaining these circuits free from fouling.
It has been determined from past experience that treatment with chlorine such that a concentration of 0.1 mg/liter free avail-able chlorine residual in the circulating water discharge to the receiving stream for 30 minutes three times a day is usually sufficient for maintaining system cleanliness although higher concentrations in the heat exchangers themselves may be needed periodically.
However, the free chlorine residual discharged I to the river will be maintained at 0.1 mg/liter or less.
The circulating water will be chlorinated by controlled injection of sodium hypochlorite into the intake water to the condensers.
Three of the twelve intakes are chlorinated at a time as a group.
The period of chlorination will be no greater than 30 minutes and will be done 3 times per day.
2.2-3
Three of the twelve intakes are chlorinated as a group.
The free chlorine residual of simultaneous samples recently taken from condenser tailpipes llA, l2A, l3A and condenser tailpipes llB, 12B, and 13B showed slight but nominal differences among the three outlet condensers, on the same order as instrument accuracy.
Therefore, for the purpose of maintaining O.l mg/l free available chlorine residual or less at the circulating water discharge it will be adequate to monitor only one of t.:he three discharges. from each unit.
The service water system will be chlorinated at a frequency not to exceed three times a day for periods of not greater than 30 minutes, and not at the same time as the Circulating Water System.
The concentration *of free available chlorine residual at the circulating water discharge to the river will be less than 0.1 mg/liter.

SALEM NUCLEAR GENERATING STATION
.ENVIRONMENTAL TECHNICAL SPECIFICATIONS JUSTIFICATION FOR PROPOSED CHANGE ETS Section 2.2.2 Suspended Solids These proposed changes to Section 2.2.2 are consistent with the Salem NPDES Discharge Permit (NJ0005622).
The pre-operational suspended solids concentration in the Delaware River in the vicinity of Artificial Island ranged up to approximately 700rng/l, with a 10 year average concentration of lSOmg/l.
Thus,* weekly sampling is adequate to detect any potential environmental impact.
DEC:kd
SALEM UUCLEAR GE!JERATDJG STATION ENVIROHMEHTAL TECHIHCAL SPECIFICATIONS JUSTIFICATION FOR PROPOSED CHANGE ETS Section 2.2.3 pH The proposed change would delete the requirement in the Environmental Technical Specifications of the pil probe accuracy (ETS Page 2.2-5) and change the specified monitoring locations and frequency to coincide with those in the NPDES Permit.
The pH probe currently being utilized at the discharge of the Non-Radioactive Chemical Waste Disposal basin is a Leeds-Northrup model SCD. 1199-64.
The accuracy of this probe varies with age and temperature according to vendor supplied information.
Routine probe correction occurs on a regular basis to compensate for probe variability.
The final pH of the basin discharge is controlled by the volume.and pH of the receiving or circulating water discharge stream ( CWS).
The pH of the CW.S has ranged historically from 6.2 to 8.1, with a mean of 7.1 during the 10 year period of record.
Buffering of the basin discharge by. the CWS will keep the pH with.in the E'l'S 1 imi ts of 6. 0 to e
- 9. Q pH units.
MP79 5 03 e
2.2.2 SUSPENDED SOLIDS Objective To insure that suspended solids released from Non-Radio-active Chemical Waste Disposal System are controlled and will not have an adverse effect on the natural aquatic en-vironment of the receiving waters.
Specification The daily average suspended solids concentration in the effluent from the Non-Radioactive Chemical Liquid Waste Disposal System shall not exceed 30 mq/liter.
The daily maximum con~
centration shall not exceed 100 mg/liter.
The daily average concentration shall be computed as the arithmetic mean of the samples taken during a calendar month of discharge.
The maximum daily concentration shall be that obtained during a single 24-hour operating period.
~
Monitoring Requirement A 24-hour composite sample shall be taken once per week from the collecting basin discharge pipe and analyzed for suspended solids using a method which is acceptable to EPA.
The sample shall be taken at the in-line pH monitoring probe in the discharge pipe.
Samples shall be taken during periods of actual discharge and only on days when the collecting basin is discharged.
Samples may be taken more frequently if desired and included in the analysis.
The suspended solids data for both the discharge and river shall be analyzed on an annual basis.. Proposed changes to this specification will be* submitted for review and approval by the NRC Staff prior to implementation.
'l
'1 ~ 4 I
Bases The suspended solids limitation is that which is required by the Salem NPDES discharge permit.
The pre-operational suspended solids data for the Delaware River in the vicinity of the Salem Station ranged up to approximately 700mg/l, with a lO year average concentration of approximately lSOmg/l.
The daily average limitation of 30mg/l and daily maximum of lOOmg/l are adequate to protect the ecology of the. Delaware River in the vicinity of Artificial Island.
2.2.3 pH Objective To insure that the pH of the effluent released from the Non-Radioactive Chemical Waste Disposal System is controlled and will not have an adverse effect on the natural aquatic environment of the receiving waters.
e. Specification The pH of the Non-Radioactive Chemical Liquid Waste Disposal System effluent shall be within the range of 6.0 to 9.0 pH units after mixing with the circulation water discharge streamo,* If this specification is exceeded, the discharge shall be terminated until the pH is corrected to within specification.
Monitoring Requirement The pH of all in-service circulating water discharges shall be grab sampled twice weekly during a discharge from the nonradio-active liquid waste basin and measu*red for pH using a PH probe.
pH measurements from the circulating water discharges receiving NRW basin wastes will be compared with those from discharges not receiving NRW basin wastes.
MP79 5 01 2.2-s
The New Jersey Department of Environmental Protection Water Quality Criteria and the Delaware River Basin Commission Effluent Quality Requirements impose stream quality limitations on the effluents entering the receiving waters.-
- These agencies consider the mixing of waste.streams to bring one or more of these streams within pH limits as acceptable.
Prior decisions by the United States Environmental Protection _Agency have indicated that waste streams could be combined with cooling water for the sole purpose of pH neutralization, as long as the final discharge was in the pH range of 6.0 to 9.0, as required by the Salem Station NPDES Discharge Permit.
Twice weekly grab sampling of the circulating water discharges is specified in tiPDES permit.
No significant change in the background pH of the river water is expected due to the operation of the Salem Station.

e SALEM NUCLEAR GENERATING STATION ENVIRONMENTAL TECHNICAL SPECIFICATIONS JUSTIFICATION FOR PROPOSED CHANGE ETS Section 3.1.1.2 Dissolved Gases The licensee requests this change primarily to allow the use of the membrane electrode method for the dissolved oxygen deter-mination.
In the December 1, 1976 Federal Register, 40 CFR 136.2 through 136.5 were amended to list the latest EPA approved test procedures for the analysis of pollutants in water.
We propose to use the membrane electrode method from this list instead of being limited to the azide modification to the Winkler method, which has proven cumbersome in field use.
The limited potential of the station to cause a significant dissolved oxygen fluctuation in the estuary plus the proven reliability of the membrane electrode method enable the licensee to conclude that this method will be "acceptable to the [NRCl staff for determining environmental effects which may occur as a result of the operation of the station."
(FES Page iv.).
With respect to precision and accuracy the EPA approved refer-ences vary in their descriptions:
Winkler Method (APHA, Pages 443-447)
"The DO can be ~etermined with a precision, expressed as a standard deviation. of about 20 ug/l in distilled water and about 60 ug/l in wastewater and secondary effluents.
In the presence of appreciable interference, even with the proper modifications the standard deviation may be as high as 100 ug/l; Still greater errors may occur in the testing of waters having organic suspended solids or heavy pollution.
Avoid errors due to carelessness in collecting samples, prolonging the completion of the test, or selection of an unsuitable modification."
Membrane Electrode Method (APHA, Pages 450-453)
"With most commercially available membrane electrode systems the operator can obtain an accuracy of 0.1 mg/l DO and a precision of 0.05 mg/l DO."
Winkler Method (EPA, Pages 51-55)
"Exact data are unavailable on the prec1s1on and accuracy of this technique; however, reproducibility is approxi-mately 0.2 ppm of DO at the 7.5 ppm level due to equipment tolerances and uncompensated displacement errors."
P78 168 19
SALEM NUCLEAR GENERATING STATION ENVIRONMENTAL TECHNICAL SPECIFICATION JUSTIFICATION FOR PROPOSED CHANGE Membrane Electrode Method (EPA, Pages 56-58)
"Manufacturer's specifications claim 0.1 mg/l repeatability with + 1% accuracy."
For the purposes intended, the above ranges are suitable.
The licensee will adhere to all provisions of the selected procedure and attempt to maximize accuracy and reproducibility.
DEC/MDL:cm 12/2 8/7 8 P78 168 20 Bases This monitoring program will provide data on the chlorine demand of the receiving water as well as the concentration of fouling organisms present.
These parameters are subject to seasonal variation and will aid in maintaining an optimum chlorination program for prevention of heat exchanger fouling.
3.1.1.2 Dissolved Gases Objective To ascertain that the dissolved oxygen level is not depressed to the extent that it may be harmful to the indigenous popula-tion of the receiving waters as a result of station operation.
Specification The dissolved oxygen levels shall be monitored once per month (weather permitting) utilizing a method which is acceptable to the EPA.
Grab samples shall be taken at the intake structure (10 ft. below the surface), the outfall of the discharge (8 ft.
below the surface), and at a point outside and downstream of the mixing zone (5 ft. below the surface).
The monitoring method selected will be carefully followed and the appropriate corrections to the specific method to accommodate estuarine conditions will be made.
3.1. 2 P78 168 16
Reporting Requirement If dissolved oxygen level is found to be less than 6 mg/l at the discharge, a comparison study of the intake, discharge and down-stream dissolved oxygen levels shall be conducted to determine if the oxygen depression has been caused by station operation.
It it is so determined, a report shall be made* in accordance with Specification 5.6.2.
Bases Monthly analyses of dissolved oxygen will aid in differentiating between normal seasonal fluctuations and changes due to station operation.
The EPA - acceptable methods are adequate to detect both kinds.
The 6 mg/liter lim~tations is required by the Water Quality Certificate issued by the Delaware River Basin Commission.

SALEM NUCLEAR GENERl\\TING STATION ENVIRONMENTAL TECHNICAL SPECIFICATION JUSTIFICATION FOR PROPOSED CIIANGE ETS Section 3.1.l.l Chlorine In a related proposed Environmental Technical Specification change, the licensee has proposed to relocate the station's installed residual chlorine monitors to a point representative of con-ditions in the actual circulating water discharge.
There the free available chlorine residual is to be continuously monitored and maintained below 0.1 mg/l.
In 1977 and 1978, the licensee measured ambient river total chlorine residual and never found a concentration exceeding 0.1 mg/l near the discharge.
Therefore, the licensee considers discharge monitoring alone as satisfactory to demonstrate no adverse impact on river water quality.
Deletion of Section 3.1.1.1 in its entirety is therefore requested.

Microplankton ETS Section:
3J..2.3 Entrainment of Planktonic Organisms -
Microzooplankton Studies The Licensee requests that the-microzooplankton program be deleted from the ETS.
Microzooplankton populations have been monitored near Artificial Island since mid-1971.
Sampling during late 1971 and through 1972 provided sufficient inventory type data upon which to formalize a field sampling program.
This program would demonstrate and monitor seasonal and spatial variation in microzooplankton composition and abundance immediately offshore of Artificial Island, in the region of the thermal plume, and in regions to the north and south of Salem.
The pre-operational phase of the ecological studies terminated in December 1976 with the-commercial operation of Salem Unit 1.
With the operation of Salem Unit 1 camB an additional objective to the sampling program.
This was to quantify the extent and the effect of involvement of planktonic organisms with the Salem Circulating Water System (CWS) intake and with the thermal component of the discharge.
In addition to the ongoing field sampling programs, an entrainment monitoring program was implemented in accordance with the ETS.
Data on the temporal occurrence and condition (where ~vailable) of the microzooplankton entrained were presented in the 1977 Annual Report.
The 1978 report is currently being prepared.
- However, field density distribution data have been abstracted from the data base and are included in Figure 1 to support recom-mendation for deletion of microplankton from all samplin~
programs.
Figure 1 demonstrates that annual mean densities of the microplankton community during the period 1973-1976, ranged from 34,000 to 43,000 organisms per cubic meter.
The micro-zooplankton community structure, (i.e., species composition) was similar from 1973-1976 during which time seven taxa were annually dominant.
These were primarily copepods, rotifers, and polychaetes.
Other taxa annually abundant were Acartia tonsa, Eurytemora affinis, Ectinosoma spp. and Gastropoda (veliger).
Community structure during the operational phase (1977 and 1978) was the same as the pre-operational period as evidenced by the same seven dominant taxa.
P79 9 51
'l..
I I
- A comparison of monthly mean densities of the microzooplankton community during the pre-operational and operational periods are also presented in Figure 1.
This figure illustrates the similarity of curves between the pre-operational years and operational years~ 1977-197~.
The annual mean density in 1977 was 32,000 organisms per cubic meter, some 2,000 lower than the lowest level observed during the pre-operational period.
This lower annual density probably reflects the anomalous depression in population density in May 1977.
The cause of this depression is unknown; however, its significance was temporary since population levels from June through December 1977 fall well within or are even higher than the range of the. preoperational period.
This suggests no irreversible impact on the population from whatever cause may have effected the May depression.
In continuing comparison, the 1978 annual mean density was 64,000 organisms per cubic meter; this is actually some 20,000 organisms higher than for any of the pre-operational years.
The similarity of the community structure, monthly total densities, and annual total densities demonstrate that there has been no significant changes in these.parameters of the microzooplankton community during the operational period of Salem Unit 1.
Whatever the level of potential impact on the microzooplankton community from the operatidn *of Salem Unit 1 it is either so low, or the populations are sufficiently-resilient, so that it cannot be demonstrated from field data.
If an impact on the microzooplankton community had occurred, it would have been evident during these first two years of operation since several generations of microzooplankters were involved.
A review of the literature concerning effects of power plant operation on microzooplankton indicates that there been no discernible effects on microzooplankton populations in the receiving water even where entrainment mortalities are very high (Lauer, 1971; Davies et al.
1974).
Since the data demonstrate that there has been no departure from pre-operation norms, the Licensee concludes that lack of impact has been demonstrated and recommends that the program of microzooplankton sampling within the field and at the intake system be deleted from ETS

ETS Section 3.1.2.1.19 Fish I
The ichthyofaunal community in the Delaware River and its tidal tributaries near Artificial Island have been monitored annually since 1968.
After the initial two years of preliminary sampling, the pre-operational phase of the study was formalized.
The monitoring program was designed to identify the fishes which occur in the vicinity of the Salem station and to describe their temporal and spatial abundance and distribution on an annual basis.
The pre-operational study was concluded in 1976 when Salem 1 became operational.
The study objectives were revised with the commencement of the first full year of Salem l* operation in 1977.
Efforts were refocused on assessing the impact of plant involvement with specific fish populations.
Based on two years of operational data, the licensee finds the existing ETS programs inadequate to quantify the impact of station operation on these populations.
More pr~cise estimate of target species population size are required.
Considering that the objective of the pre-operational monitoring programs have been_met and that their value and quantifying station operational impact is minimal, we recommend a present ETS monitoring program pertaining tidal tributary sampling, beach seining and night sampling be terminated.
The rationale for each of these recommendations is presented below.
Tidal Tributary Program Sampling in tidal tributaries near Artificial Island began in June 1969.
The objectives were to:
- 1) identify species and life stages that utilized the selected creeks, their purpose and the period of utilization; 2) describe seasonal changes in species composition and distribution; and 3) determine the importance of tidal creeks as spawning and nursery areas.
The resultant data base has been analyzed in annual reports which adequately describe the utilization of these tidal tributaries by the fish community.
The objectives of the program have been met.
Current emphasis of the fisheries studies is on quantifying the extent and effect and involvement of target species with Salem, specifically with thermal discharge and the circulating water system (CWS) intake structure.
The tidal tributaries and the fishes in them are isolated from the discharge and intake.
All thermal plume protections and measurements demonstrate that the.
thermal discharge will not cause alteration of habitat or physiochemical conditions in the tidal tributaries.
Access to
I
- Tidal Tributary Program (Cont'd) these tributaries will not be restricted or denied.
Due to the remote location of the CWS intake structure relative to these tributaries, fish population which occur in them and could potentially be subjected to* impact will only occur when these populations enter or leave the tributaries.
Since impact on riverine populations cannot be quantified with.
the data collected in the tidal tributary sampling, it is the licensee's recommendation that this portion of the program be discontinued.
River Seine Program Seine sampling of the Delaware River near Artificial Island was begun in 1968.
The objectives of this program were to determine the relative abundance and distribution of fishes which utilized the shore zone.
Sufficient data has been generated to meet these objectives.
In consideration of the change in study emphasis, the con-
.tinuation of the seine program was evaluated.
Among the target species, only bay anchovy occurs in abundance in the shore zone and is vulnerable to seine sampling.
However, its occurence in the shore zone is minor in comparison to the population size offshore.
On this basis, the trawl program has been designed to estimate the population of bay anchovy; any supplemental seine program would be of minimal value.
The ETS seine program was further evaluated to determine the feasibility of detecting localized impact (control vs. effected stations) on several non-target species including Atlantic silverside, Atlantic menhaden and mummichog, which are abundant in shore zone but are taken in low numbers offshore.
Analysis indicated that the present level of sampling effort could not assure detection of differences (80% confidence) of less than 300% between stations within one year.
It was also determined that an 80% certainty of detecting a 50% difference between two of ten station means (x) at a 5% significance level would require more than ten times the effort of the present program.
Such an increase in effort would not be cost effective.
These findings are consistent with an evaluation of similar programs by Gore (1977), which found a "large heterogenicity in the population distirbution of many species".
Gore recommended that "attempts to quantify changes in shore-zone fish population size be curtailed unless such an eatimate is deemed crucial".
It is the licensee's recommendation that since such an impact assessment cannot adequately be made, that the seine program be eliminated *

Night Sampling Night sampling in compliance with the present ETS is done as part of the simultaneous se~ne and trawl sampling program.
This is a non-ETS program which collects samples at two locations during daylight and night.
This program has been conducted in the Delaware River near Artificial Island since 1971.
The objectives of this program are to:
- 1) determine the inshore and offshore distribution of common fishes taken at each site; 2) determine the size and growth rate of the fishes at each location; and 3) determine diurnal differences in these parameters.
A sufficient data base has been generated to meet these objectives.
The sampling frequencies and qualitative nature of the data inherent in a program of this type does not permit identifi-cation or quantification of impact.
Any night sampling-in the Artificial Island reach of the Delaware River is restricted by the problems related to commercial shipping and other hazards to safe navigation.
Even if such a program could easily be implemented, it would not be cost effective.
It is the licencee's recommendation that night sampling be deleted.

I SALEM NUCLEAR GENERATING STATION ENVIRONMENTAL TECHNICAL SPECIFICATION JUSTIFICATION FOR PROPOSED CHANGE ETS Section 3.1.2.1.2 Terrestrial Studies The ETS change would delete all reference to diamond back terrapin monitoring.
Nesting diamondback terrapin, Malaclemys terrapin terrapin, has been monitored at three sites on the Delaware River* near Artificial Island since 1975.
The sites are:
Sunken Ship Cove, located 0.6 miles to the east of Salem; Hope Creek Beach, 2.3 miles to the southeast; and Liston Point, 2.8 miles to the southwest.
A study by Roy F. Weston Inc. (1978) indicates that none of the monitoring sites are within the thermal plume, although terrapin nesting in Sunken* Ship Cove may swim through it.
Annual data on nesting activity, duration of nesting, tagging efforts, number of nests and eggs laid, and hatching activity from 1975 through 1977 have been described in the Artificial Island Annual Progress Reports.
Collection of data for 1978 has been completed.
Data from two seasons of post-operational study and two seasons of pre-operational study form an adequate base for identifying poten-tial impacts of the Salem thermal plume on nesting.
Analysis of the data shows no significant change in nesting activity between pre-and post-operational years.
Nesting began each year on Qr within a few days of 10 June, and continued for four to six weeks, ending usually around mid-July.
The actual duration of nesting is probably dependent on favorable weather conditions and the physiological condition of the population.
Nesting activity appears to be increasing at Liston Point and Hope Creek, although there is no significant difference between con-secutive years (Fig. 1).
Activity from 1975 through 1978 increased 63% at Liston Point and 138% at Hope Creek.
Activity at Hope Creek was significantly lower in 1975 compared to 1978.
Data for Sunken Ship Cove do riot indicate a trend and there is no significant difference between years.
Any decrease in nesting activity at sunken Ship Cove will probably not be due to the thermal but as a result of human disturbance.
The beach at Sunken Ship Cove is used for picnicking, sunbathing, swimming, boating, and fishing.
Observations of use by the public seem to be increasing each year.
The number of fishermen present at each visit during 1978 was recorded.
Fishermen w~re present on 23 (85%) of the 27 visits made during the active nesting period.
Justification: (Cont'd)
The average number of people observed on the beach was 4 (range:
2-12) with a mode of 2.
More people probably use the beach on weekends.
This represents a fairly constant disturbance.
Terrapin appear to be very sensitive to disturbance by humans as they will not approach a beach with a person on it, and generally interrupt nesting at any stage upon sensing a human (Burger and Montevecchi, 1975, Hardin 1977).
Terrapin are also frequently
.hooked by fishermen at sunken Ship Cove and subsequently killed.

SALEM NUCLEAR GENERATING STATION ENVIRONMENTAL TECHNICAL SPECIFICATIONS JUSTIFICATION FOR PROPOSED CHANGE ETS Section 3.1.2.1.2 Terrestrial Studies The Licensee requests that hhe requirement for bird surveys be deleted from the ETS.
Bird surveys have been conducted in the vicinity of Artificiai Island on the Delaware River from Hope Creek Jetty to the mouth of Alloway Creek since 1975.
Annual data on species composition, relative abundance, and distribution from 1975 through 1977 have been described in the annual progress reports.
Data from two years of operational and two years of pre-operational studies form an adequate base for identifying adverse impact of the Salem effluent on species composition, abundance, and distribution of birds in the immediate area of the Salem station.
Yearly summaries of the more common birds observed since 1975 are presented in Table 1.
Annually, 22-45 additional species were_ observed although they were not found in sufficient abundance to permit a quantitative assessment.
In order to make the data more comparable-between years, only observations for March through December are included, the period of peak abundance.
The mallard, Anas platyrhyhchos, was the only species to show an apparent change in abundance during the operational period.
An increase in numbers has been observed during the winter months.
The winters of 1976-1977 and 1977-1978 were more severe than the two previous winters, freezing most of the marsh and freshwater areas in the region, forcing waterfowl to use the open water of the river.-
Bonaparte's gull, Larus philadelphia, was the only species to exhibit even a temporary change in abundance due to plant operation~ A flock of approximately 150 immature Bonaparte's gulls were regularly observed feeding in the discharge area during April and May, 1977.
During 1975 and 1976, this species was observed for only a two week period in either April or May.
The plant was down during most of April and May in 1978.
Distribution of birds on the river other than gulls has remained unchanged since S~lem began operation.
More gulls have been observed in the area of the discharge and sluice outlets when the station is operating than during the pre-operational period.
However, no apparent change in abundance of gulls over the total area surveyed has been observed since operation began.

SALEM NUCLEAR GENERATING STATION ENVIRONMENTAL TECHNICAL SPECIFICATIONS JUSTIFICATION FOR PROPOSED CHANGES ETS SECTION 3.1.2.2 Impingement of Organisms Impingement of fishes and b~ue crab has been monitored concur-rently at the Salem ~irculating water system (CWS) and service water system (SWS) intakes since April 1977.
Daily impingement estimates have been reported to the Commission in monthly.
impingement monitoring program reports.
Estimated total monthly impingement, for April through December 1977 has also been reported (Brundage and Hassel, 1978).
During all months when both CWS and SWS intakes were operating, impingement at the SWS intake only accounted for a small frac-tion of total station impingement.
During April through December 1977 impingement at the SWS intake comprised less than 0.7% of the fish and less than 0.2% of the blue crab estimated to have been impinged by the station (Brundage and Hasel, 1978).
Species composition and relative abundance of the dominant organisms were generally similar at both intakes.
To further delineate the contribution of the SWS intake to total station impingement, daily estimates of weakfish and white perch impingement at both intakes were compared.
Only dates where there were both CWS and SWS collections were included in the evaluation.
During the period June 19 through September 28, 1978, impingement of weakfish at the SWS intake comprised* only 0.18% of the estimated total number impinged by the station.
On a daily basis, the SWS intake impinged at most 0.7% (July 4) of the station weakfish total (see Impingement Monitoring Program Reports Nos. 15, 16, 17, and 18).
During November 1, 1977 through March 16, 1978 impingement of white perch at the SWS intake accounted for 0.5% of the esti-mated total number impinged by the station.
On days when the CWS was fully operational, the SWS intake impinged at most 2% of the station total (see Impingement Monitoring Program Reports Nos. 8, 9, 10, 11, and 12).
In addition to very low impingement at the SWS intake, severe icing conditions during December, January, and February fre-quently prevented the collection of samples required by the ETS.
The entire area surrounding the SWS trash collection baskets becomes glazed with ice making work in the area extreme-ly hazardous.
P79 5 01
- ---- ---- ---- ~---- -- - ------ *-
The sampling nets become frozen inside the SWS baskets and per-sonnel frequently have to climb down into the baskets and chip the sample out of the net.
On several occasions the lock on the access door to the baskets became frozen delaying sample collec-tion.
Additional SWS samples often had to be taken during the following weekend to make up for samples completely lost during the regularly scheduled sampling days.
These extraordinary efforts were made to insure that required number samples were taken in compliance with the ETS.
Based on the above considerations, the Licensee feels that the cost (in time and manpower) of SWS sampling greatly outweighs the quality and value of the data obtained.
We, therefore, recommend that service water impingement monitoring be terminated.

SALEM NUCLEAR GENERATING STATION ENVIRONMENTAL TECHNICAL SPECIFICATIONS JUSTIFICATION FOR PROPOSED CHANGES ETS Section 5.6.1.1.la Annual Non-Radiological Environmental Operating Report The present time period (90 days) within which the Annual Non-Radiological Environmental Operating Report must be submitted to the NRC is insufficient to process the quantity and diver-sity of data collected during the preceding calendar year.
This is particularly true now because data relevant not only to the NRC programs but also to the Environmental Protection Agency 316(b) Demonstration are being collected.
In fact, an agreement has been reached with the EPA to provide them with periodic reports keyed to seasonal observations prior to sub-mitting the final 316(b) Demonstration.
In view of this agreed upon reporting schedule, and because the NRC Annual Non-Radiological Environmental Operating Report will contain* to a considerable degree the same material, the Licensee considers it inefficient to prepare separate reports on different schedules.
Therefore, it is requested that the Licensee be permitted to submit the Annual*Non-radiological Environmental Operating Report to the NRC within 165 days after January 1 of each year.
This would allow the NRC report to coincide with one of the EPA reports which is due on June 15 of each yeai.
In accordance with ETS Secti6n 5.6.1.1.lb, the NRC would also receive a copy of the other semi-annual report as well as the final 316(b) demonstration.
Although Regulatory Guide 4.8 suggests a 90-day reporting period, the NRC has shown flexibility with other licensees.
The Environmental Technical Specifications for Three Mile Island Unit 1 {NUREG-0432, February 8, 1978) allow the Licensee approximately four months in which to prepare the report.
