2.JL Chemical 2..L 1 pH, Specification The pH of the discharges from the holding tanks for the demineralizer and condensate polisher regeneration solutions shall be maintained in the range of 6.0 to 9.0 SU.
Discharges from these tanks shall not be initiated if the sampled regeneration solutions in the tanks have a pH outside of the allowed range.
Surveillance Requirement The contents of the regeneration solution holding tanks shall be grab sampled and the pH measured in accordance with the EPA Guide-lines for Establishing Test Procedures ~for the Analysis of Pollutants, s
40 CFR 136.
Sampling shall be conducted prior to each release of the contents of the tanks.
Reporting Recuirement The results of the Surveillance for the LCO shall be reported in accordance with Table IV.1 of Section 5.6.1.a.

< Bases The Limiting Condition of Operation will control the pH of the discharged decineralizer and condensate polisher regeneration solutions within the range 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 Cc z=onwealth and EPA have 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 deter-minations of the Commonwealth of Pennsylvania and EPA that the maintenance of regeneration tank discharge pH within the ranges of 6.0 to 9.0 SU will not result in unacceptable impact on the receiving water.
s Each regeneration of the two stage feed water demineralizers and the condensate polishing decineralizers will produce acidic and caustic solutions of differing characteristics, which will be neutralized on a batch-by-batch basis. Therefore, monitoring the pH of each batch after neutralization but prior to release is necessary to assure compliance with the specified limits.

.O TMI October 21, 1976 2.j[. 2 Biocide Specification The concentration of free residual chlorine in the plant discharge shall not exceed a monthly average value of 0.2 mg/l nor an instantaneoun maximum value of 0.5 mg/1.
If sampling indicaces that these limits are being exceeded, the addition of chlorine shall be terminated im=ediately.
The biocide application program shall be reviewed by plant personnel and modified as necessary to comply with the above limits prior to the resumption of chlorination of the system involved.
Surveillance Requirement The plant discharge line shall be grab sampled and analyzed for free residual chlorine in accordance with the EPA Guidelines for Establishing Test Procedures for the Analysis of Pollutants, 40 CFR 136.
Sampling shall be done on a once per week basis, with a minimum sampling interval of 3 days,during chlorination at a time when the maximum free chlorine residual is expected at the plant discharge.
All weekly values determined during a calendar month shall be arithmetica11y averaged to determine compliance with the specified monthly average limit.
1564 124 7
L l'1 THI Reporting Requirement The results of the surveillance conducted for this LCO shall be reported in accordance with Table of Section 5.6.1.a.
For each sample,,
the licensee shall reoort the date of the sample, the free residualThe chlorine concentration measured and the analysis procedure used.
monthly average free residual 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.a. (2).
Bases This Limiting Condition of Operation will limit the concentration of free residual 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 pro =ulgated EPA Steam Electric Generating Point Source Category Effluent Guidelines and Standards dated October 8, 1974.
This evaluation resulted in the adoption of the aforementioned Guideline level for a residual chlorine limit in the plant discharge to the Susquehanna River.
The EPA Effluent Guidelines only restrict the free residual chlorine concentration in tha effluent and not the total residual chlorine concentration.
Based on the provisions of the Second Memorandum of Understanding, the NRC will not impose more stringent limitations on a licensee as a provision of any license than those limitations established pursuant 1564 125 8
C,

Specification The total residual chlorine concentration of the plant discharges shall be measured.
Surveillance Recuirement When chlorination is being practiced at the plant, the plant 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 as allowed by the EPA Guidelines Establishing Test Procedures for the Analysis of Pollutants 40 CFR 136.
This surveillance program shall commence with the initial application and discharge of residual chlorine to Unit 2 cooling systems and continue for the life of the station or until approval for termination or modification is obtained from NRC.
Reporting Recuirement The results of the surveillance conducted under this program shall be reported in accordance with Section 5.6.1.a.

made for any measurement of total residual chlorine in excess of 0.2 mg/1.
Bases Chlorination of pir.nt cooling water systems is* permitted with controls only on the free chlorine residual fraction of the discharge.
Toxicity to aquatic biota occurs from both the free and combined residual chlorine fractions.
Therefore, a measure of the potential toxicity 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 concentration 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 intermittent chlorine exposure of 0.2 mg/l total residual chlorine has been suggested by Brungs (1973), EPA (Tebo,1975) and Basch and Truchan (1974).
In the environmental statement, Section 5.3.3, it was recognized that chlorination of plant systems at t'he level permitted by the NPDES Permit could lead to discharge of total residual chlorine values up to 3 times the measured values for free residual chlorine.
Past experience was also cited, stating that total residual chlorine values did not often exceed 0.2 mg/1.

, Monitoring total residual chlorine in the plant effluent at the same time as free residual chlorine measurements for ETS 2.3.2 will provide necessary information on the relationship between the residual chlorine fractions. This will allow a comparison with the previous operating history at the site and a confirmation of the predictions of FES Section 5.5.3.
The establishment of the specified report level will also alert the staff to toxic conditions in the vicinity of the plant outfall and to unanticipated operating conditions at the plant.

_ Bases The environmental assessments, as defined in the FES-OL of 1972 (Section V.C.2) and the Supplement to the FES-OL of 1976 (Section 5.5.2.3) determined that impacts to the benthos of Lake Frederic area of the Susquehanna River may result from the operation of Three Mile Island Nuclear Station.
Impacts 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 worn Limnodrilus hoffmeisteri.
Since benthic organisms are sedentary and cannot " avoid" adverse conditions, they are useful indicators of water quality.

Sampling shall be conducted once per week at approximately a 7-day interval, during the period March through July.
Reporting Requirement Data, program results, and interpretation of environmental impacts shall be reported as per the routine report schedule of Section 5.6.1.B.
Bases The environmental assessments, as defined in the FES-OL of 1972 (Section V.C.2) and the Supplement to the FES-OL of 1976 (Section 5.5.2.2) determined that impacts to the ichthyoplankton of Lake Frederic may result from the operation of 7hree Mile Island Nuclear Station.
Impacts may occur due to the entrainment of fish eggs 1564 136

I and larvae as a result of mechanical, thermal and biocidal effects.
Operation entrainment studies of Unit 1 have indicated low numbers 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.
For the latter reason, far-field sampling will be undertaken 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.

Data, program results, and interpretation of environmental impacts shall be repor.ted as per the routine report schedule of Section 5.6.1.B.
The findings of this program shall be reviewed by NRC after the receipt of the routine report covering the period of the second year of full power commercial operation of Unit 2.
At that time the program and findings shall be assessed for their adequacy and possible modification.

~
l I 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 performc.1.
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 of 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 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 loss of 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 disappearing if they approach the limit of their temperature preferendum.

Impingement Specification Organisms shall be collected from the traveling screens to identify species and to determine the number and weight removed by impingement.
A subsampling scheme approved for this program is provided in the Procedures Manual.
Organisms collected from the traveling screens shall be disposed of in a manner consistent with requirements of the U. S. Environmental Protection Agency and/or state regulatory agencies.
Surveillance Requirement This surveillance program shall commence when Unit 2 begins commercial operation and continue until approval for termination has been obtained from the NRC as per Section 5.6.3.C.
Impinged organisms from each Unit shall be sampled concurrently for one continuous twenty-four hour period twice each month.
Reporting Requirement Results of this study shall be submitted as per Section 5.6.1.
The reports shall contain the following information for each unit:
the date of the sample, the taxa collected, the number or estimated number impinged in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for each taxon and the weight (g) of each taxon, 1564 140 as
- MI the number of pumps operating during each sample, and the inlet water temperature. A comparison between an impingement experience at Unit 1 versus Unit 2 shall be provided.
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 or organisms collected on the traveling screens will ensure that a reasonable estimate of the organisms impinged in the intake structure will be identified and enunerated. 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 by the applicant has been conducted during the operation of Unit 1.
Results to date of this study indicate that impinge-ment losses due to operation of Unit 1 are minimal.
Unit 2 utill:es both a separate intake structure and intake canal.
Monitoring of impinge-ment losses due to the combined operation of Units 1 and 2 will assure that losses associated with the operation of Unit 2 are no greater than those experienced at Unit 1.
Estimates of fish losses due to impingement, used in conjunction with fisheries studies conducted on the intake /receivit.g and estimates of losses due to entrainment, will allow an overall evaluation of impact sustained to the fishery by plant operation.

3.1.2.a. (3)Entrainment of Plankton, Eggs and Larval Forms Specification Ichthyoplankton (fish eggs and larvae) shall be collected at the intake structures to identify taxa and life stages and to estimate numbers and weight lost by cooling system entrainment. Methods and materials approved for this program are provided in the Procedures Manual.
Surveillance Requirement This surveillance program shall commence when Unit 2 begins commercial
~
operation and continue until approval for termination has been obtained in accordance with Section 5.6.3.C.
Entrained ichthyoplankton shall be collected semi-monthly during the period, April through July. On each sampling day, collections shall be stratified on the basis of day versus night variations.
b Reporting Requirement Results of this program shall be reported in accordance with Section 5.6.1.
The reports shall include the following information:
sampling date, time of day, species or taxon, life stage, number and weight, densities, and percent live.

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 ichthyo-plankton are of higher concern, although no adverse impacts are expected.
Predominant species in the fishe y., 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 thermal stresses.
Monitoring will provide data for assessing the level of ichthyoplankton entrainment relative to the ichthyoplankton populations in the river.

Aerial Remote Sensing Specifications Vegetation communities of the site and vicinity shall be aerially photographed annually to detect and assess the significance of damage, or lack thereof, as related to cooling tower drif t dis-persions. Photography will be done by aerial overflight.
Upon identification of specific drift damage impacts, the applicant shall submit for NRC review and possible modification, a detailed plan to ascertain the following:
(1) Correct functioning of all cooling tower drif t eliminating systems; (2)
Specific plant response to stress resulting in either premature senescence and death or recovery; (3) Specific actions to be initiated to replace or restore-vegetative biota which, due to cooling tower drif t, have undergone abnormal senescence resulting in death.
Methods and materials approved for implementation of this program are provided in the Procedure Manual.
Surveillance Recuirements This surveillance program shall commence at initial criticality of Unit 2 and shall be reviewed by NRC after a ceriod of five years for possible modification or deletion as per Section 5.6.3.
Aerial photography will be conducted once per year during late summer or early fall.

Reporting Reqe _.ements The results of the aerial photography drif t surveillance program shall be summarized as per routine report schedule of Section 5.6.1.a.
Representative photographs should be made available upon request of this staff.
The findings of this program shall be reviewed by NRC after the receipt of each routine report.
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) determined that impacts to surrounding vegetative communities may result 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 drif t field is the means recommended for detection of possible adverse effects of drif t.
Such adverse' effects may most often be associated with either episodic high level dosages of chlorine or chronic low level chlorine dosages. Aerial photography will monitor and record the presence or absence of vegetative effects due to cooling tower drift deposition.

s TMI October 22, 1976 4.0 Special Surveillance and Study Activities 4.1 Residual Chlorine Surveillance Procram Specification The licensee shall sample the plant discharge plume in the Susquehanna River to determine th'e spatial distribution of the total residual chlorine when the licensee initiates a discharge of free residual chlorine at the maximum level allowed by the NPDES Per=it (i.e.,
0.2 mg/l average free residual chlorine or 0.5 mg/l maximum free residual chlorine).
Surveillance Recuirement The licensee shall analyze the waters of the plant discharge plume for total residual chlorine and shall determine the location of the 0.2 mg/1, 0.1 mg/l and 0.05 mg/l total residual chlorine isopleths in the Susquehanna River.
The surface area and volume of water within each isopleth shall also be determined.
All analyses shall be conducted as allowed by the EPA Guidelines Establishing Test Procedures for the Analysis of Pollutants, 40 CFR 136.
This special surveillance program shall cocmence with the initiation of plant chlorine discharge at the maximum level allowed by the NPDES Permit.
This special surveillance program shall terminate when the specified isopleths, areas and volumes have been detersined for the operating conditions un' der which the maximum chlorination program is conducted.

, TMI Reporting Requirement The results of the surveillance conducted under this program shall be reported in accordance with Section 5.6.1.a.
The results shall include the locations of the isopleths, the surface areas defined by each, the estimated volume of water within each isopleth, the method of analysis, the date of analysis, and the plant and river discharge flow rates.
Bases In the Supplement to the Environmental Statement, Section 5.3.3, it was 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 residual 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 within a short distance of the outfall. This program will provide the necessary information to quantify the portions of the Susquehanna River which will experience residual chlorine concentrations in excess of recommended icvels.

Aerial Remote Sensing One of several aerial photographic techniques may be utilized.
- Natural and false color infared photography.
- Multispectral photography employing black and white infared film, employing four spectral bands (blue, green, red, and infared).
Selection of either or both of the above techniques should include the following parameters:
- study area around cooling towers should be relatively small (about 25 square kilometers)
- the scale for full coverage should 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 not exceed 1:6000.
Photographic ' interpretations will correlate" data from simple ground truthing surveys and drift modelling with areas of stress and non-stress, as seen on the photographs in order to assure accuracy of photographs.
Ground truthing will include a transect analyses through areas of maximum predicted drift deposition as well as any areas shown by photographic evidence to be experiencing stress.
Impact on vegetation, if any, will be noted as to general characteristics and as to the type of symptoms on leaves and buds or general decline of plants.
All general ground truthing data collected in the field will be gathered with specific intent for utility in the 1"nterpretation of the remote sensing imagery.
1564 164 d7

Timing of aerial photography and ground truthing should be selec'.ed to coincide with periods of maximum predicted dr$ft deposition damage, preferably from August 15 to September 15 meteorological conditions permitting.
