CPSES/ER (0LS) 6.2 APPLICANT'S PROPOSED OPERATIONAL MONITORING PROGRAMS O
This section supercedes the presentation contained in Section 6.2 of the original ER, and discusses the environmental monitoring programs that will be conducted during CPSES operation. ~Some aspects of the prograra will be developed in more detail in the Environmental Technical 1
Specifications (ETS) which will be established in accordance with applicable NRC Regulations. In addition, the terms of the National Pollutant Discharge Elimination System (NPDES) pemit issued by the U.S. Environmental Protection Agency (EPA) form the basis for some portions of the themal and chemical monitoring requirements. In general, those facets of the program covered directly by the NPDES 1
permit are not described in detail witFin this section.
6.2.1 RADIOLOGICAL MONITORING The radiological monitoring program, operational stage, will be a 4
continuation of the preoperational program previou' sly described in O Section 6 1.s end Pere 9rePh 3/4.12.1 of the Stenderdiized Redioio9icei 1 Effluent Technical Specification, NUREG 0472. The operational phase i will be continued for the first three full years of commercial operation to verify the adequacy of source control. If data from the program and effluent calculations indicate that doses and concentrations associated with a particular pathway are sufficiently
'
small, the number of media sampled in the pathway and the frequency of
~
sampling may be appropriately reduced.
i 6.2.2 CHEMICAL EFFLUENT MONITORING i
Under normal operating conditions, chemicals (other than chlorine) will not be discharged from the plant into Squaw Creek Reservoir (SCR), but will be routed-to an onsite evaporative storage pond. This pond has an ,
impermeable clay liner to prevent contamination of the local surface and groundwater rer orces, and has been designed to accommodate the

CPSES/ER (OLS) non-radioactive che7ical wastes accu,ulated during the expected operating life of the plant. h A chlorine mininization study will be conducted during the first year of operation of each unit to develcp a sound, scientifically based 1
chlorination progran to maintain condenser efficiency using a mininu1 o' ' rine. This study has been cpproved and will be perfonned under
-
conditions in the NPDES permit.
6.2.3 THERMAL EFFLUENT MONITORING The nooitoring of themal effluents will be perfomed as specifie1 within the NPDES pemit. Under the tcms of the pemit, telperatures will be measured where the circulating water discharge canal meets SCR.
Additionally, two SCR noni+.oring prograns will be undertaken to assess the thernal efficiency of SCR and themally characterized biological collecting stations (see Section 6.2.6.1.1).
6.2.4 METEOROLOGICAL MONITORING h Prior to fuel load of Unit One, the neteorological measurenents prograa of the Co,anche Peak Stean Electric Station shal! consist of the following:
- 1. A primary neteorological measurements program.
2 A b ickup meteorological measure 1ents systen.
2.
- 3. A system for making near real-time predictions of the atmospheric effluent transport and diffusion.
- 4. A capability for remote interrogation, on dunand, of the atmospheric measurenents and prediction systeas by the licensee, energency response organizations, and the NRC Staff.

) The major component of operating and maintenance expense (0&M) is fuel cost. Using 1980 Dollars and a 70 percent annual load factor, the annual fuel cost and other representative 0&M costs are as follows:
1 (Thousands)
Q33 Fuel cost $69,956
,
All other O&M cost $20,972, j Total $90,928 ,
Fuel cost is based upon 1980 market values of the various fuel cycle
- onponents. The 0&M costs are based current estimates in 1930 dollars.
The major cost eieraents included in the non-fuel portion of 0&M costs are operating and maintenance labor, other maintenance expense, quality assurance, home office technical support, license fees and directly related taxes. Ad valorem taxes and insurance are not included here, but are included in the fixed charges shown in Section 8.2.1.4.
8.2.1.3 Pacomni<sioning Cost
,
Decommissioning of CPSES is projected to comence in the year 2022. 2 The cost is estimated to be'$50 million per Unit (1980 dollars). See Q33 Section 5.8 for details of this estimate.
8.2.1.4 Power Generating Cost On the basis of the foregoing estimates of capital, direct operating and decomissioning costs, it is estimated that the 1980 present value of power generating cost over the first 30 years of useful life is 2

Fixed Charges $ 3,172 $
Operating, Maintenance and Fuel Costs $ 2,078 2 Allovance for Deccanissioning $ 100 Total (lifetime cost) $5,350 The fixed charges were determined by using a levelized fixed charge rate of 20% of the capital cost of the facility. This annual cost, when multiplied by the present worth factor for a 30-year econaaic life at a 10% discount rate (9.4269) is equal to:
(0.20) X ($2,239,417,000) X (9.4269) = $4,222,152,000 This $4,222 million value is representative of the 1983 (mean c.o. date of the two units) present value. When this value is present worthed to 1980 at 10% (a factor of 0.7513) the 1980 present value is:

($4,222 uillion) X (0.7513) = $3,172 million Q37 g The canbined ope, ations maintenance and fuel cost was developed from the annual cost shown in 8.2.1.2 ($90,928,000) by assuming an 8%
escalation factor in these costs over the 30 year economic life of the plant. When discounted at 10%, the equivalent present value for any year is detemined by multiplying the 1980 annual cost by the compound sum factor for 8% escalation for that year and then multiplying this product by the present worth Factor for that year.

Using the above cupper release rate a copper concentration can be inferred as follows: The copper going into the solution will be in the fom of elemental copper, Cu+2, and-copper oxice., Cu0.
, In lakes, copper in solution is in (1) ionic fom (Cu+2);
(2) complexed in organic materials; (3) absorbed and q precipitated on solids; and (4) incorporated in other
'
crystalline structures. Most copper is tied up in the crystalline structure of sedimentary materials, less is in organic complexes and dead seston, and very little is in 4 solution. In natural waters, the concentration of Cu+2
^
ranges from 1 to 50 pg/1.1 The ionic form, Cu+2, has a bionagnification factor of about 30 - 60x103 and is the 2
.
fom of copper most related to aquatic life toxicity.2 t
The copper entering the lake with the cooling water will rapioly reach equilibriun with a complex chemical species leaving 7.ittle in solution as toxic ionic copper. The anount can be quantified once the ionic equilibrium is identified and then perturbated by the rates of loss at the Pagenkopf 3 , among others,-suggests that the low condenser.
copper concentrations in water can be des.ribed by a carbonate equilibriua of:
i
- -
+
CuC0 3 + -Cu+t + -C 30 _ 2-, K = 2.34x10 10.M (1) 3q _ ,, , ,
where C0 3
-2 represents the carbonate balance. Carbonate concentrations in natural waters range from 50 mg/l to 150 mg/l (8.3x10-4 to 2.5x10-3 g),
The above equilibrium is perturbated by the Cu+2 addition.
If'C 1is the total addition in a year, and 'x is the amount that ends up as Cu+2 in solution with (Cy - x) added to the Q/R-68a AMENDMENT 2 DECEMBER 1980' ,

(3) x/Ci=_-C0 L3 +K-

_
which is controlled by the carbonate slance. . The anount of copper remaining in solution is, therefore, 2.7x10-7 times the anount added.
After the first month, there is 3.29x106 gm/yr added to 140,000 Acre-Ft. (1.72x108 m3) of lake. It is assuaed that over a year, the added copper will go into solution uniformly throughout the lake due to plant pumping; uptake '2 O settling, decay and resolution by organic material; and, general lake seasonal circulation. The addition, C1 , over the lake volume is equivalent to a concentration. addition of 0.20 mg/l per year. The addition to Cu+2 in solution becomes, from Equation (3), 0.54x10-7 mg/l per year, or 0.54 x10-4 pg/l per year. Even over a large number of years, this is an insignificant addition to natural
'
background levels of 1 to 50 ug/l.

R64. No records exist to estimate the amount of sludge produced per year at CPSES. It is known that the frequency of O siudge removei during the constrection phese wes approximately twice per year.
The applicant, after discussion with the wastewater treatant facility's manufacturing representative, projects the following:
i l In operating the 30,000 gallon per day Extended Aeration Process system, the maximum amount of sludge ancicipated 2 would be 2200 gallons per quarter with a solids
,
concentration of 10,000 to 30,000 mg/ liter. This amount and the frequency of sludge removal will vary depending upon the nuraber of ' people on site and day to day operating techniques. During the operational phase,'when sludge removal is required, TUGC0 will contract with an approved l commercial firm to remove this sludge and dispose it at a permitted disposal area.-
