Dear Mr. Regan:
Attached are pages 11.1-2 and 11.2-2 which were inadvertently left blank in the original submittal of the Environmental Report Operating License Stage for the Susquehanna SES.

SUMMARY
BENEFIT-COST ANALYSES The importan e of Susquehanna SES in providing an econ ic and reliable powe supply for the Applicant, the Cooperat' a'nd the PJN Xnterconne ion was demonstrated in Chapter 1.
T e economic and social effec.
s of station construction and opera ion were discussed in Chap er 8.
Other benefit-cost informa ion has been provided throughout this report.
It is the purpos of this chapter to summarize and weigh the overall benef i s and costs of operating the complet station.
This final bal ncing must, of necessity, be qualitatx e, since it is not poss'e to quantify all of the station's ben fits and costs in corn rable units of measure.

- 11. 1.
1 DIRECT BENEFITS The primary benefits resulting from op ation of the Susquehanna SES are those inherent in the value o
t e generated electricity which will be delivered to meet cust er eeds.
The station will provide an average annual generatio of 12.
billion KWH based on a
70% capacity factor for the 2100 We stati n
Distribution of the energy based on pro jected 1981 data is 4.
billion KWH-Residential, 2.7 billion KWH -Com ercial,
- 4. 5 illion KWH-Industrial,
- 0. 5 billion KWH Ot er and l. 1 bil on KMH System Use and Losses.
As noted previ sly, the value this energy cannot be readily monetized, s'e its true worth elates to customer
- needs, safety, conven ence, etc., that it rovides.
Operatinq cost savings that esult from operation of he station as planned have been demons rated in Chapter 1.
For e ample, in 1983 with both Susquehanna nits in-service, operatinq osts for the Applicant were project d to be from
$70 million to
$ 85 million lower than would e possible if the station were ot operating.
Also as deta'led in Chapter 1 and Appendix A, clays from current in-service schedules for the station are likel to add substantially to th Applicant's overall cost of service over the life of the statio Fo example, if both of the Susqueh nna units were delayed on
- year, and if load growth were as low a
the Very Low load pro ection, then the Applicant's cost of service was estimate to increase by about
$850 million ($ 130
'illion 1980 prese t worth) over the assumed station life.
Furthermore, it has also been noted that station operation will conserve oil, prov' advantages of a diversified capacity mix

- 11. 2 COSTS INCURRED The costs of the project include economic costs, in terms of
- dollars, and environmental costs, expressed in a variety of units.
As detailed in Chapter 8 the 1981 present worth of the station's primary internal costs over its first 30 years of operation is projected to be approximately
$ 3.6. billion.
The environmental effects are discussed below with respect to the three major divisions of the biosphere:
the aquatic, atmospheric and terrestrial regions.
The environmental impact (costs) must be considered for both absolute magnitude and degree of importance.
In the following discussions of environmental costs, an attempt has been made to evaluate these factors.
- 11. 2. 1
~AUATIC The aquatic environmental effect of the station includes the effect on surface waters and on ground water.
In both instances the physical effects of the station water intake and the chemical, radiological, thermal and physical effects of liquid discharges must be considered.
11.2. 1.1 Surface Water Water for cooling and domestic use for Susquehanna SES is obtained from the Susquehanna River.
The cooling water for the station is passed through the condensers into cooling towers where rejected heat is dissipated.
Make-up for water lost by evaporation, drift and blowdown is taken from the river.
A chlorine biocide and anti-fouling agent is added to the cooling water to work in conjunction with a mechanical system to prevent micro organism buildup on the condenser tubes.
The cooling tower blowdown is returned to the river.
The blowdown is treated and monitored to maintain chlorine residuals and dissolved solid concentrations within the applicable water quality standards of the Commonwealth of Pennsylvania.
Liquid radioactive wastes are treated in a separate system.
The calculated exposures from Susquehanna SES are within limits of Appendix I to 10CFR50.
Domestic water is supplied via the makeup water treatment system.
Appropriate treatment and storage is provided.
