3-3 Bases The purposes of this monitoring requirement are to assure that (a) the difference between intake water tescerature and discharge water temperature caused by station operation, (b) the temperature of the cooling water being discharged, and (c) the rate of temperature change of the discharged cooling water comply with the requirements of NPOE5 permit 9A-0009920 issued to the Metropolitan Edison Company by the U.S. Environ-mental Protection Agency.

The FES-OL for the Three Mile Island Nuclear Station, Unit 2, provides an analysis of the potential thermal effects of the cooling system discharge on the water quality and aquatic biota of the adjacent portions of the Susquehanna River. Based on the volumes of water discharged during normal operation and the minimum river ficw condition, the analysis of thermal effects indicates that the mixed mean receiving water temperature would be increased less than 0.14*C (0.2S*F).

The analysis also indicates that the thermal plume is expected to be limited ta a relatively small area of the river.

The analyses performed in the FES-OL (1972 and 1976) concluded that limiting the temperature rise across the station, the maximum discharge temperature, and the rate of temperature change during station operation based on design parameters and information provided in the ER and other supporting documents would not incuce calefaction of an excessive portion of the Susquehanc.a River nor would it result in excessive, irreversible, or irretrievable damage to the biota or water quality of the receiving waters.

Anticipated occasional, brief duration, temporary temperature excursions are not excected to exert significant biological effects on Susquehanna River coculations.

Modeling studies have indicated that discharging water no hotter than 30.5 C (87'F) will result in a Susquehanna River temperature regime that is co=patible with the Commonwealth of Pennsylvania water cuality require-ments. An NPDES permit has been issued to the licensee providing for this effluent limitation excep. when the ambient river temcerature exceecs 30.5'C (87*F). The existing NPOE5 permit also limits any rise in discharge temcerature to no more than 2.8'C (5*F) during any one hour. The NPOE5 permit further provides for exceptions to the 2.S*C (5.0*F) temcerature rise limitation by recognizing that for short and infrequen.t periods during the year the comoination of atmoscheric conditions and river temcera-ture may occur which causes the MDCT to be incapable of removing sufficient heat to meet the limitation.

34 The above monitoring program will provide the information needed to determine whether the station is operating in ar environmentally acceptable manner and as analyzed in the Sucplement to the FES-OL and in staff testimony before the Atomic Safety and Licensing Board." In addition, it will provide input to the programs cescribed in Suosections 3.1.1 and 3.1.2 which 1re portion. of the continuing study of the effect of thermal

,disenarges from the Three Mile Island Station on the water quality and aquatic life in the Susquehanna River. The Special Thermal Plume Mapping stucy required uncer Section 4.2 will also use this information as a basic data input.

3-5 3.1.1.a.(2) gH Environmental Monitorino Recuirement During normal creration, the contents of the holding tanks for the demineralizer and condensate polisher regeneration solutions shall be sampled prior to being discharged and the pH measured in accorcance with the procedures prepared by the licensee per Section 5.5.

This monitoring program shall commence at the initial discharge from the holding tanks of Unit 2 subsecuent to issuance of the operating license and shall continue until accroval for termination or mocification of this monitoring requirement is c:.tained from NRC per Subsection 5.7.1.

Action The results of this monitaring program shall be su=marized, analyzed, interpreted, and reporter, in accordance with Subsection 5.6.1.

For each release, the license shall record the date cf each sample, the pH measured and the method of analysis used.

A nonroutine recort st all be submitted in accordance with Subsection 5.6.2.b. if the the rd of the discharges from the holding tanks falls outside the rarge st'pulated by the effluent limitations prescribed by the Commonwealth of P:rasylvania and the U.S. Environmental Protection Agency in the cartificates and permits issued to the licensee pursuant to the provisions of Section 401 and 402 of PL 92-500, as cited in Section 5.4 of these ET5.

Bases This monitoring program will provide necessary information to determine wnether the pH of the discharged demineralizer and condensate polisner regeneration solutions are witnin tne range necessary for the protection of aquatic biota and whether the facility is cen.g acerated, with respect to pH of ' discharges, in the manner evaluated in the FES-OL. The Commonwealth of Pennsylvania and the U.S. EPA Region III evaluated the collection, treatment and discharge systems for the demineralizer and condensate polishing regeneration solutions with respect to the Susquehanna River water quality standards and the FWPCA Steam Electric Generating *nint Source Category Effluent Guicelines and Standarcs, respecti'vely.

The Commonwealth and E?A have determined, through issuance of the lics 2ee of a water quality certification and NPDES permit PA-0009920 (pursuant to FhPCA Sections 401 and 402, respectively), that these recuirements will be met uncer proposed oceration.

In the Succlement to the FES, subsection 5.3.3, the staff, in its analysis, determined that t.! maintenance of regeneraticn tank discharge pH within the ranges of 5.0 to 9.0 will not result in unacceptable imcact on the receivirq wa ar.

3-6 Each regeneration of the '

tage feedwater demineralizers and the concensate polishing cemiiieralizers will procuce acidic and caustic solutions of differing cnaracteristics. These will be neutralized on a batch-by-batch basis or by an on-line neutralization systen.. Monitoring tne pH of each batch after neutralization but prior to release is, there-fore, necessary to determine wnether station cperation is within accectable limits.

Siccice Environmental Monitorino Recuirement When chlorination is being practiced at the station, the station discnarge from outfall serial numcer C01 as identi.'ied in NPCES permit no. PA-CC09920 shall be grab sampled at a time curing the chlorination period when the maximum residual chlorine concentration is expected to be present and analyzed for total residual enlorine utili:1ng the accerometric titration tecnnique in accordance with the Procedures prepared by the license per Section 5.5.

This Environmental Monitoring Requirement shall be applicaole under normal station ope ~ ration.

This monitoring program shall ecmmence with the initial application and discharge of resicual chlorine frca Unit 2 cooling systems subsequent to issuance of the ocerating license and continue until approval for termina-tien or modification of this monitoring requirement is obtained from NRC per Subsection 5.7.1.

Action The results of the monitoring conducted under this program shall be summarized, analyzed, interpreted and reported in accordance with Subsection

5. 6.1.

For each measurement the licensee shall record the date of analysis, total residual chlorine concentration, and method of analysis used.

A non-routine report as specified in Subsection 5.6.2.b shall be made for any measurement of total residual chlorine in excess of the effluent limi-tations or special conc!tions prescribed by the Commonwealth of Pennsylvania and the U.S. Environmental Protection Agency in tne certificates and permits issued to the licensee pursuant to the provisions of Sections 401 and 402 of PL 92-500, as cited in Section 5.4 of these ETS.

Bases Chlorination of station cooling water systams is permitted by the NF3E5 Permit witn limitations on the concentratien sf free available chlo. ine in the station discharge; on the duration of discharge of both fres avail-able and total residual chlorine; and on simultaneous discharge o'. eitar free available or total residua! chlorine from both units.. Toxicity to aquatic biota occurs frem both the free and comoir.ed available residual enlorine fractions. Therefore, a measure of the putential toxicity of the station's discharge is the measure of total residual chlorine. This monitoring crogram will provice information en the magnitude of the total residual enlorine concentration in the station discharge during plant chieri-nation to cetermine wnetner concentrations harmful to other users are present.

An effluent limit for protection of warm water fish species to intermittent chlorine ex;osure of 0.2 mg/l total residual enlorine nas been suggested cy 3 rungs (1973), E?A (Tabo, 1975) and Bascn and Truchan (1974).

\\,

3-8 In Sues-ction 5.3.3 of the Supplement to FES, it was recogni::ed that chlori-nation of station systems at tne level permitted by the NPOES Permit could lead to discnarge to total residual chlorine values up to 3 times the measured values for free available chlorine.

Past experience was also cited, stating that total residual chlorine values did not oftan exceed 0.2 mg/1 Monitoring total residual chlorine in the station's effluent will allow a comparison with the previous operating history at the site and a confirma-tion of the predictions of the Supolcment to the FES-OL, sucsection 5.5.3.

The establishment of the specified nonroutine report recuirement will also alert the staff to toxic conditions in the vicinity of the station outfall and to unanticipated ocerating conditions at the plant.

Suspenc'd solics may also interfere with respiratory processes and decrease light penttration so that the food scurces of the be6thos may be recucad.

Increased sedi=entation may result in increased numbers of some dcminant organisms, espe-ially the annelid worm Limnedrilus hoffmeistari.

Since benthic organisms are sedenta y and cannot " avoid" adverse conditiens, they are useful indicators of water quality and environmental change.

The environmental assessments mace in the FES-OL of 1972 (Section V.C.2) and the Sucplement to the FES-OL of 1976 (Section 5.5.2.2) determined that imoacts to the ichthyoplankton of Lake Frederic may result frem the operation of Three Mile Island Nuclear Station.

Imcacts may occur due to the entrain-ment of fish eggs or larvae as a result of mechanical, thermal and biocidal effects. Operational entrainment studies of Unit 1 have indicated low numoers of larval fishes at the intake. Those which have been taken, however, have been represented by several important forage (shiners and darters) and recreational (catfishes, sunfishes, perch) species. The densities of larvae were higher at the intake than at the discharge and always higher at night than during the day for both far-field and entrainment samples.

Fish larvae have been taken duriag far-field sampling under.taken at night frem Aoril to August, the perice which encoccasses the peak' spawning season of the Lake Frederic fishes.

. le majority of fisn larvae have been taken during May and June.

3-17 Bases The environmental assessmer.ts made in the FES-OL of 1972 (Section V.C.2) and the Sucplement to the FE5-OL of 1976 (Section 2.2.2.1) determined that impacts to the fish populations of L3':e Frederic may result from the operation of Three Mile Island Nuclear Station because of imoingement of adult and juvenile fishes and the entrainment of fish eggs and larvae.

This sampling program will be performed to assess the relative significance of these phencmena on the fish peculations. Additionally, several spe:ies support an active recreational fishery in Lake Frederic and signt be suoject to potantial impact. These species are sunfish and catfisn (several species each), rock bass, smallmouth bass, walleye, and possibly cracpie and carp. Operational impingement studies et Unit 1 have shown that the most frequently captured fish species were tassellated darter, channel catfish, spottail shiner, and spotfin shiner. The catfish is an important recreational species, while the carter, spettail shiner and catfish are imcortant food items in the diets of several other recreational species (i.e., rock bass, smallmouth bass, walleye).

Some fish species may be attracted to the discharge. A concentration of fishes could result in increased or altered predation, cisease, or change in physical condition.

In local areas wnere there is a prolonged temperature shift, even if only a few degrees, there may be a shift in comparative abundance of species, with some scecies disacpearing if they approacn the limit of their temperature preferendum.

This program will provide information necessary for the evaluation of the effects of THINS operation on the ichthyofauna of the Susquehanna River.

Imoincement of Orcanisms Environmental Monitorina Receirement Organisms shall be cellected from the traveling screens and identified to species or icwest possible taxon. Mesh size of collection devices shall approximate that of the traveling screens.

All samoles shall be collected and all analyses shall be performed in accorcance with the procedures prepared by the licensee per Section 5.5 of these ETS. For each sample, the folicwing physical data shall be provided:

nuncer and type of river water pumas operating and their ratec capacity; and intake tamperature.

This monitoring pregram shall commence at initial attainment of normai coeration of Unit 2 and continue until approval for modification or termina-tion of this monitoring requirement has been obtained frcm the NRC in accordance with Subsection 5.7.1.

Action Results of this pregram shsil be summarized, analyzed, interpreted and recorted in accordance with Subsection 5.6.1.

The reports shall contain the follcwing in+ormation: date of the sample, the taxa collected, the actual or estimated number and weight of each taxon impinged for each sacole period, the time averaged volumetric flow rate of Uni 2 cooling water and the average intake water temoerature.

A comparison between the imoingement experience at Unit i versus Unit 2 shall be provided.

Organisms collected from the traveling screens shall be disposed of in a manner consistent with requirements of apprcpriata Federal, State and Lccal regulatory agencies and described in the precedures dccument required b-. Section 5.5.

Bases The magnitude of loss and the potential impact to the acuatic ecosystem in the vicinity of the power station resulting from impingement of aquatic organisms en the traveling screens is not precisely known n'or is it 120 016

3-19 detarminable on a theoretical basis alone. Sampling of organisms collectec on the traveling screens will ensure that a reasonable estimate of the organisms impinged on the intake structure will be identified and enumerated.

This information wnen coccined with the results of the far field biological surveillance program in the intake / receiving waters will provice the empirical basis on which to judge the impact of Unit 2 operation.

Impingement monitoring has been conducteo by the acplicant during the operation of Unit 1.

Results to date indicate that impingement losses due to operation of Unit 1 are minir.al. Unit 2 utili::es a separate intake structure. Monitoring of impingement losses will establisn the relative efficiencies and total losses associated with the operation of Units 1 and 2.

3-2C 3.1.2.a.(3) Entrainment of Ichthvcolankton Environmental Monitorina Recuirement Icnthycplankton (fish eggs and larvae) shall be collected during tne months of April through August at the intake structures to identify taxa and to estimate numcers lost by cooling system entrainment. Gear used in the collection of encrained ichthyoclankton snall be comparable to that used in the General Ecological Survey for far-field monitoring of ichthycplankton.

Collections shall be made in accordarce with the Procedures prepared by the licensee per Section 5.5.

On each sampling day, collections shall be made so as te identify day-night variation in concentration of organisms.

Specimens shall be identified to the icwest practical taxon. This monitoring program shall cemence at initial attainment of normal operation of Unit 2 and continue until approval for modification or termination of this monitoring requirement is obtained frem the NRC in accordance with Subsection 5.7.1.

Action Results of this program shall be summarized, analyzed, interpreted and reported in accordance with Subsection 5.6.1.

The reports shall include the following information:

sampling date, time of day, species or taxon, life stage (eggs or larvae), numcer collected and concentration (number /100 cubic mettes).

Bases Adverse effects en local planktonic populations due to entrainment were not anticiptted (FES, Units 1 and 2, Decemcer 1972) and none have been detected curing Unit 1 coeration (FES Supplement, Unit 2, July 1976).

Continuation of phytoplankton and :ocplankton monitoring during Unit 2 cperation hac been judged unnecessary (ibid, page 6-2).

The effects on local fish populations due to entrainment of ichthycplankton are of higner concern. The predominant species in the areas deposit eggs on sheltered bottom areas.

Larvae and early juveniles emigrating from sucn areas adjacent to the intake may be sucjected to entrainment for the period of time that they remain in the icwer water strata..All ichthycolankton passed through the closed-cycle cooling system are presumably killed by the combined mechanical, chemical and thermal stresses.

Mcnitoring will provide data for assessing the level of ichthycolankten entrainment relative to the ichthycplankton populations in the river.

Photography shall be done by aerial overflight. Aerial phetograchy shall be conducted once per year during late summer or early fall. Timing of aerial pnotography and ground truthing should be selected to coincide with periods of maximum predicted drift de osition camage, preferanly frem July 15 to September 15, meteorological conditions permitting.

Monitoring will be in accordance with the Procedures prepared by the licensee per Section 5.5 and will include either:

(a) Color infrared photograpt.- or (b) Multispectral or multiband photography. The scale for full coverage shall be acequate to enable identification of vegetative damage over relatively small areas of terrain. Some circumstances may warrant inspec-tion of photographs discerning individual trees.

Such scale should be in the interval between 1:1000 and 1:10,000 as aporopriate to resolve impacted features.

Photographic interpretations shall correlate data from ground truthing and ground inspection surveys and drift modeling with areas of stress and non-stress, as seen on the photographs for purposes of verification of results and interpretation. Ground truthing surveys shall cover, but not be limited to, the first year of the aerial photographic monitoring program.

This surveillance program shall commence at initial attainment of normal operation of Unit 2 and shall be continued for at least 5 years. At the end of five years the 1 f censee may request modification or termination of this monitoring requirement per Subsection 5.7.1.

4-1 4.0 Scecial Studies and Recuirements 4.1 Res cual Chlorine stucy Procram Recuirement The licensee shall sacole the station discharge plume in the Suscuehanna River to determine the spatial distribution of the total residual w..lorine when the licensee initiates a planned discharge of free available chlorine at the maximum level allowed by the NPDES Permit No. PA-0009920 (i.e.,

0.2 mg/l average free available chlorine or 0.5 mg/l maximum free available chlorine).

The licensee shall analyze the waters of the station's discharge pluce for total residual calorine and shall determine the location of the 0.2 mg/1, 0.1 mg/l and 0.05 mg/l total residual enlorine isepleths in the Susquehanna River, The surface area and volume of water within each isepleth shall also be determined. All analyses shall be conducted in accordance with the Precedures prepared by the licensee per Section 5.5.

This special study program shall cc==ence with the initiation of station chlorine discharge at the maximum level allowed by the NPDES permit. This special study program shall consist of a series of surveys, one survey under each of the following conditions:

a.

One-unit cperation eith maximum chlorination) when the Suscuehanna 3

River flew rate is less than the =edian flow rate of 566 m /sec (20,000 cfs).

42 Bases In the Succlement to the Final Environmental Statement, Sucsection 5.3.3, it was recognized that chlorination of station systems at the level permitted by the NPCES Permit coule lead to discharge of total residual chlorine values uo to 3 times the measured values for free available chlorine. These levels would exceed a recognized criterion for exposure of aquatic biota to resicual chlorine. The Staff analysis indicated that the residual chlorine levels in the discharge plume would be reduced to levels celow tne criterion within a short distance of the outfall. This program will provide the necessary information to identify the portions of the Susquenanna River which will experience residual chlorine concentrations in excess of recommended levels.
