The analyses performed in the FES-OL (1972 and 1976) concluded that limiting the temperature risa across the condensers during station operation as specified above will not induce califaction of an excessive portion of the Susquehanna River nor will 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 of up to 10.5'C (19*F) are not expected to exert significant biological effects on Susquehanna River populations.

Section 5.3.3 of the Draft Supplement to the FES for Three Mile Island Nuclear Station, Unit 2, endorses the NPDES issued by the State of Pennsylvania under FWPCA Sections 302 and 402 which stipulates a maximum l

AT of 2.S*C (5'F) . This endorsement indicates NRC agreement that plant f

operation within the limits indicated above will assure no excessive, irretrievable, or irreversible damage to the aquatic environment or to its biotic inhabitants.

The above surveillance program will provide the information needed to assure compliance with the LCO and will, in addition, provide input to the surveillance program described in Sections 3.1.1 and 3.1.2 which are portions of the continuing study of the effects of thermal discharges from the Three Mile Island Nuclear Station on the water quality and aquatic life in the Susquehanna River. The Special Thermal Pluce Mapping 9tudy required under Section 4.2 of this ETS will also use this information as a basic data input.

.by the licensee in accordance with Section 5.5. Sampling and measure- . .

ment shall be conducted prior to each release of the contents of the tanks.

Bases ,

The Limiting Condition for Operation will control the PH of the discharged de'mineralizer and condensate polisher regeneration solutions within the rance necessary for the protection of aquatic biota. 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 Point Source Category Effluent Guidelines and Standards, respectively. The Commonwealth and FPA. here determined, through issuance of the licensee of a water quality certification and NPDES permit PA-0009920 (pursuant to FWPCA Sections 401 and 402, respectively), that these requirements will be met under proposed operation. In the FES, Section 5.3.3, the staff accepted the determinations of the Commonwealth of Pennsylvania and EPA that the maintenance of regeneration tank discharge pH within the ranges of 6.0 to 9.0 will not result in unacceptable impact on the receiving water.

Applicability

~

Thic Limiting Condition for Operation shall be applicabic under all conditions of station operation.

Action _

If sampling indicates that these limits are being exceeded, the addition of chlorine shall be terminated i==ediately. The biocide application program shall be reviewed by plant p rsonnel and modified as necessary to comply with the above limits prior to the resumption of chlorination of the system involved.

The results of the surveillance conducted for this LCO shall be reported in accordance with Section 5.6.1. For each sample, the licensee shall report the date of the sample, the free available chlorine concentration measured and the analysis procedur used. The monthly average free avaiable chlorine concentration shall also be reported for each month. Results of the surveillance which indicate a violation of the LCO shall also be reported in accordance with Section 5.6.2.b.

1564 029

Surveillance Recuirement The plant discharge line shall be grab sampled and analyzed for free available chlorine utilizing the amperometric titration technique in accordance with the Procedures prepared by the licensee in accordance with Section 5.5. Sampling shall be performed weekly during chlorination at a time when the maximum free availabl chlorine residual is expected at the plant discharge.

All weekly values determined during a calendar canth shall be arithmetica11y averaged to determine compliance with the specified monthly average limit.

Bases This Limiting condition of Operation will limit the concentration of free available chlorine in the plant discharge to a level consistent with that of the NPDES Permit.

The U. S. Environmental Protection Agency Region III has issued the licensee NPDES Permit No. PA-0009920 as a result of an evaluation of the operation of the plant against the promulgated EPA Steam Electric Generating Point Source Category Effluent Guidelines and Standards dated October 8, 1974.

This evaluation resulted in the adoption of the aforeme.:tioned Guideline level for a residual chlorine limit in the plant discharge to the Susquehanna River.

1564 030 Based on the provisions of the Second Memorandum of Understanding, the NRC will not impose more stringcat limitations on a licensee as a provision of any license than those limitations established pursuant to authority under

- s-. .-

22 -

the Federal Water Pollution Control Act Amendments of 1972. Therefore, the staff has incorporated the NPDES concentration limits and monitoring frequency as part of these ETS.

~ ~

The discharge of free available chlorine at the'leveis permitted by the Limiting Condition of Operation have been assessed by the staff (FES Supplement, Section 5.3.3). It was found that in the vicinity of the discharge, toxic conditions may occur, but that significant adverse impact on the local fishery resource is not expected.

3.0 Environmental Monitoring 3.1 Nonradiological Monitoring 3.1.1 Abiotic 3.1.1.a Aquatic 3.1.1.a. (1) Plant Chemical Releases _

Environmental Monitoring Requirement When chlorination is being practiced at the station, the station discharge shall be grab sampled at the outfall on a weekly basis corresponding to the sampling conducted under ETS 2.3.2 and analyzed for total residual chlorine utilizing the amperometric titration technique in accordance with the Procedures prepared by the licensee in accordance with Section 5.5.

This Environmental Monitoring Requirement shall be applicable under all I

conditions of station operation. This surveillance program shall cc==ence with the initial application and discharge of residual chlorine from Unit 2 cooling systems and continue until approval for termination or modification is obtained from NRC as per Section 5.6.3..

Action The results of the surveillance conducted under this program shall be reported in accordance with Section 5.6.1. For each measurement, the date of analysis, total residual chlorine concentration, and method of analysis used shall be recorded.

A non-routine report as specified in Section 5.6.2.b. shall be made for any measurement of total residual chlorine in excess of 0.2 mg/1.

Bases Chlorination of plant cooling water systems is permitted with controls only

~

on the free _available chlorine residual' fraction of the' discharge. Toxicity to aqua

~ ~ ~

biota occurs from both the free and combined available residual $hlorine fractions.

Therefore, a measure of the potential tcxicity of the plant discharge is the measure of total residual chlorine. This surveillance program will provide information on the magnitude of the total residual chlorine concentratica in the plant discharge during plant chlorination to determine if concentrations harmful to other water users are present. An effluent limit for protection of warm water fish species to intermitten chlorine exposure of 0.2 mg/l total residual chlorine has been suggested by Brungs (1973), EPA (Tebo,1975) s

, and Basch and Truchan (1974) .

In the environmental stater.ent, Section 5.3.3, it uns recognized that chlorination of plant systems at the level permitted by the NPDES Permit could lead to discharge of total residual chlorine values up to 3 times the measured values for free available chlorine.

may occur as a result of thermal additions. Species diversity, composition, and biomass in the immediate site vicinity are most susceptible to thermal alterations, and to changes in sedimentation, turbidity, and dissolved oxygen levels. Suspended solids may also interfere with respiratory processes and decrease light penetration so that the food sources of the benthos may

' be reduced. Past studies have shown that increased sedimentation may result in increased numbers of some dominant organisms, especially the annelid worm Limnodrilus hoffmeisteri.

Since benthic organisms are sedentary and cannot " avoid" adverse conditions, they are useful indicators of water quality.

of'Three Mile Island Nuclear Station. Impacts may occur due to the entrainment of fish eggs and larvae as a result of mechanical, thermal and biocidal effects. Operation entrainment studies of Unit I have indicated low nu=bers 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 during far-field sampling undertaken at nicht from March to July, the period which encompasses the peak spawning season of the Lake Frederic fishes, The majority of fish larvae have been taken during May and June.

In local areas where there is a prolonged temperature shift due to thermal discharges, even if only a few degrees, there may be a shift in comparative abundance of species, with some species disappearing if they approach the limit of their temperature preferendum.

Bases The environmental assessments made in the FES-OL of 1972 (Section V.C.2) and the Supplement to the FES-OL of 1976 (Section 5.2.2.1) determined that impacts to the fish populations of Lake Frederic may result from the operation of Three Mile Island Nuclear Station. Impacts may result due to impingement of adult and juvenile fishes and the entrainment of fish eggs and larvae. In order to assess the relative significance of these phenomena on the fish populations, this lake-wide sampling program will be performed. Additionally, several species support an active recreational fishery in Lake Frederic and might be subject to potential impaction -

sunfish and catfish (several species each), rock bass, smallmouth bass, walleye, and possibly crappie and carp. Operational impingement studies 1564 044

~

t 4

of Unit 1 have shown that the most frequently captured fish species were tasse11ated darter, channel catfish, spottail shiner, and spotfin shiner.

The catfish is an important recreational species, while the darter, spottail shiner and catfish form important 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 warm thermal discharge, particularly during the cooler seasons. A concentration of fishes could result in increased or altered predation, disease, or change in physical condition. In local areas where there is a prolonged temperature shift, even if only a few degrees, there may be a shift in comparative abundance of species, with some species disappeni.=ng if they approach the limit of their temperature preferendum.

Action Results of this study shall be submitted in accordance with Section 5.6.1.a. The reports shall contain the following information: date of the sample, the taxa collected, the actual or estimated nc=ber and weight of each taxon impinged for each sample period, the time averaged volumetric flow rate of plant cooling water and the average intake inlet water temperature.

Organisms collected from the traveling screens shall be disposed of in a manner consistent with requiree-nts of appropriate Federal, State and local regulatory agencies and described in the procedures document required by Section 5.5.

Bases The magnitude of loss and the potential impact to the aquatic ecosystem in the vicinity of the power plant resulting from impingement of aquatic organisms on the traveling screens is not precisely known or determinable on a theoretical basis alone. Sampling of organisms collected 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 when combined with the results of the far field biological surveillance program in the intake / receiving waters will provide the empirical basis on which to judge the impact of plant operation.

Impingement monitoring has been conducted by the applicant during the operation of Unit 1. Results to date indicate that impingement losses due to operation of Unit 1 are minimal. Unit 2 utilizes both a separate intake structure and intake canal. Monitoring of impingement losses due to the combined operation of Units 1 and 2 will establish the relative efficiencies and total losses associated with the operation of Units 1 and 2.

. . Bases Adverse effects on local planktonic populations due to entrainment were not anticipated (FES, Units 1 and 2, December,1972) and none have been detected during Unit 1 operation (FES Supplement, Unit 2, July,1976).

Continuation of phytoplankton and zooplankton monitoring during Unit 2 operation has been judged unnecessary (ibid, page 6-2).

The effects on local fish populations due to entrainment of ichthyoplankton are of higher concern, although no adverse impacts are expected. Pre-dominant species in the fishery deposit eggs on sheltered bottom areas.

Larvae and early juveniles emigrating from such areas adjacent to the intake may be subjected to entrainment for the period of time that they remain in the lower water strata. All ichthyoplankton passed through the closed-cycle cooling system are presumably killed by the combined mechanical, chemical and ther=al stresses.

Monitoring will provide data for assessing the level of ichthyoplankton entrainment relative to the ichthyoplankton populations in the river.

Cl) Ae-ial Remote Sensing Environmental Monitoring Recuirement Vegetation coc= unities of the site and vicinity shall be aerially photo-graphed annually to detect and assess the significance of damage, or lack thereof, as related to cooling tower drift dispersions. Photography shall be done by aerial overflight. Aerial photography shall be conducted once per year during late summer or early fall. Timing of aerial photography and ground truthing should be selected to coincide with periods of maximum predicted drift deposition damage, preferably from August 15 to September 15, meteorological conditions permitting.

I One of the following aerial photographic techniques shall be utilized:

- Color and/cr black and white infrared photography.

- Multispectral or multiband photography.

Selection of either or both of the above techniques shall include the following parameters:

- study area around cooling towers shall be relatively small (about 25 square kilometers);

- the scale for full coverage shall be adequate to enable identification of vegetative damage over relatively small areas of terrain. Some circumstances may warrant inspection of photographs illustrating individual trees. Such scale should be in the interval between 1:1000 and 1:10,000 as appropriate to resolve impacted features.

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 criticality of Unit 2 and shall be reviewed by NRC after a period of five years for possible modification or deletion as per Section 5.6.3.

Action Description of the program, results, and interpretive analyses of environmental impacts shall be reported in accordance with Section 5.6.1. Results reported shall contain (as per Table 5.6-16) but not be limited to: sampling date; time of day; film type (s); spectral band (s); and scale.

Bases The environmental assessments, as defined in the FES-OL of 1972 (Section V.C.1.a) and the Supplement to the FES-OL of 1976 (Section 5.5.1 and 6.5) determined that impacts to surrounding vegetative communities may resul t from the operation of Three Mile Island Nuclear Station cooling towers. Impacts may occur due to cooling tower drift deposition causing vegetative stress.

Reconnaissance and aerial photographic inspection of biota in the drift field is the eans recommended for detection of possible adverse effects of drift.

Bases l

In the Supplement ts the Environ = ental Statement, Section 5.3.3, it was recognized that chlorination of plant systems at the level permitted by the

' NPDES Pecnic could lead to discharge of total residual chlorine values up N to 3 times the measured values for free available chlorine._ These levels. ,,

would exceed a recognized criterion for exposure of aquatic biota to residual chlorine. The staff FES analysis indicated that the residual chlorine levels in the discharge plume would be reduced to levels below the criterion vit.hin a short distance of the outfall.

and estimation of effective stabilization should be kept and be available on the site for a period of two years. Results reported shall contain (as per Table 5.6-15) but not be limited to: surveillance date; estimated size of erosion problem area; type of stabilization program; date of effective stabilization.

Bases Periodic maintenance activities or severe weather may cause instances along the transmission line corridors where soil or slope stabilization will be necessary. In the Supplement to the FES-OL of 1976 (Section 6.5) it was recommended that during normal transmission line inspections, notations be made of any areas requiring reseeding and confirmation of action to remedy erosion in these areas.

Routine corridor surveillance techniques will identify erosion problem areas and coupled with appropriate erosion control steps will insure that such areas becoce stabilized.
