1.0 Definitions Accuracy: normally refers to the difference (error or bias) between the mean, 2, of the set of results and the value X, which is accepted as the true or correct value for the quantity measured. It is also used as the difference between an ind.4.vidual value Xt and 2. The absolute accuraev of the mean is given by X - 2 and of an individual value by Xi - 2. The relative accuracy of the mean is given by di s)/X, X and the percentage accuracy by 100 di - X)/X.
Aerial Remote Sensing: The measurement or acquisition from aircraft or spacecraf t of information on some property of an object or phenomenon by a recording device that is not in physical or intimate contact with the object or phenomenon under study. The technique employs such devices as the camera, radio frequency receivers, and radar systems.
. m Annually: Annually is once per calendar year at intervals of twelve calender months, plus or minus seven days.
Batch Release: A batch release is the discharge of fluid wastes of a discrete volume.
Calibration: An instrument or device calibration shall be the adjustment, as necessary, of the output such that it responds with the necessary range and accuracy to known values of the parameter (s) which the instrument sensor or device monitors. The calibration shall encompass the entire circuit including the sensor, indicatory control feature, alarm and/or trip function (s), and shall include the functional test. The calibration may be performed by any series of sequential, overlapping or total circuit steps such that the entire circuit is calibrated as specified. The methodology

. i and measurement of instrument accuracy and precision of calibration shall be recorded in the plant records.
Closed Cycle Cooling: The circulating water, after passing through cooling towers and recirculated back to the condenser intake with the exception of the blowdown which is discharged to the receiving water body.
Combined Available Chlorine: chlorine existing in water in chemical combination with ammonia or organic nitrogen compounds.
Composite Sample: A combination of individual samples obtained at regular intervals over a time period. Either the volume of each individual sample is proportional to the flow rates over the time period used to produce the composite.
Continuous Release: A continuous release is the discharge of fluid waste of a non-discrete volume, e.g., from a volume or system that has an input flow during the continuous release.
Daily Average Concentration: Daily average concentration means the arithmetic average of all daily determinations of concentration made during a calendar month. Daily determinations of concentration using a composite sample shall be the concentration of the composite sample. When grab samples are used, the daily determination of concentration shall be the arithmetic average of all the samples collected during that calendar day.
Daily Maximum Concentration: Daily maximum concentration means the maximum concentration recorded for any calendar day.
1564 011- [
~
3-
] q Free Available Chlorine: Chlorine existing in water as hypochlorous acid and hypochlorite ions.
Functional Check: A functional check shall be the injection of a simulated signal into a circuit at the primary sensor to verify circuit behavior during observation. Instrument checks shall permit observation of an established value other than a value observed when the instrument is de-energized. Sensor checks t..all permit observation of an established value while disconnected from its normal circuit function and subjecting the sensor to the parameter (s) normally monitored. Functional checks shall include alarm and/or trip functions but may be blocked from performing the ultimate specified function.
Functional Test: A functional test shall be verification of operability by performing all specified functions using the parameter (s) which the instrument sensor or device monitors.
I Grab Sample: A grab sample is an individual sample collected in less than fifteen minutes.
Ground Truth or Ground Data Survevs: Supporting data collected on the ground and information derived therefrom, as an aid to the interpretation of remotely-recorded survey, such as aerial imagery, etc. Generally, this should be performed concurrently with the airborne surveys.
Herbicides: Chemicals that kill plants or inhibit their normal growth.
Infrared, photographic: Pertaining to or designating the portion of the electromagnetic spectrum with wavelengths just beyond the red end of the visible spectrum; generally defined as from 0.7 to about 1.0 um, or the useful limits of film sensitivities.

Manner of Herbicide Application: Herbicides may be applied to target plants by any of the following methods:
- a. Basal injection in which selected individual trees receive herbicide injections beneach the bark;
- b. Basal application in which individual plants are treated with pellets i
or sprays applied to soil at the base of the plant; I
- c. Selective foliar spray (spot treatments or directed spray) in which individual plants are sprayed with ground-based equipment;
- d. Broadcast application in which herbicide is distributed either as pellets or spray uniformly over the entire predetermined area o.
land; i
- e. Aerial application in which entire seg=ents of the corridor are treated primarily by broadcas't applications employing various types of aircraft.
Monthly: Monthly is once during every calendar month at intervals of 30 days plus or minus three days.
Multispectral or Multiband Photographs: A color picture produced by assigning a color to a particular spectral band.
Normal Operation: Operation of the station at greater than 2% of rated thermal power in other than a safety emergency situation. 1564 013 NPDES Permit: NPDES Permit is the National Pollutant Discharge Elimination System Permit No. PA0009920 issued by the Environmental Protection Agency to Metropolitan Edison Company.

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. Past experiente was also cited, stating that total residual chlorine values did not often exceed 0.2 mg/1.
Monitoring total residual chlcrine in the plant effluent at the same time as free available chlorine measurements for ETS 2.3.2 wi11' provide necessary information en the relationship among the residual chloriae 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.

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

3ase, T564 041 The environmental assessments made in the FES-OL of 1972 (Section V.C.2) and the Supplement to the FES-OL of 1976 (Section 5.5.2.1) determined that impacts to the ichthyoplankton of Lake Frederic may result from the operation
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.

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.

1 3.1.2. a. (2) Impingement of Organisms Environmental Menitoring Requirement Organisms shall be collected from the traveling screens and identified to species or lowest possible taxon. Mesh size of collection devices shall approximate that of the traveling screens. Organisms impinged for a continuous twenty-four hour period shall be sampled in accordance with the Procedures prepared by the licensee as per Section 5.5.
The actual or estimated number and weight removed by impingement for each taxon shall be determined as per Section 5.5.8.
Applicability This surveillance program shall commence with the date of initial criticality for Unit 2 operation and continue until approval for modification or termination has been obtained from the NRC in accordance with Section 5.6.3.
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.
1564 046

~
. A comparison between the impingement experience at Unit 1 versus Unit 2 shall be provided. .
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.

3.1. 2.a. (3) Entrainment of Ichthvoolankton Environmental Monitorine Reouirement Ichthyoplankton (fish eggs and larvae) shali "be collected during the months of March through May at the intake structures to identify taxa and to estimate numbers lost by cooling system entrainment. Cear used in the collection of entrained ichthyoplankton shall be comparable to that used in the General Ecological Survey for far-field monitoring of ichthyoplankton.
Collections shall be made in a,ccordance with the Procedures prepared by the licensee as per Section 5.5. On each sampling day, collections shall be made so as to identify diurnal variations in concentration of organisms.
Specimens shall be identified to the lowest practical taxon.
I Applicability This surveillance program shall coc=ence with the date of initial criticality for Unit 2 operation and continue until approval for modifi-cation or termination is obtained from the NRC in accordance with Section 5.6.3.
Action Results of this program shall be reported in accordance with Section 5.6.1.a. The reports shall include the following information: sampling date, time of day, species or taxon, life stage, number collected and concentration (nu=ber per 100 cubic meters).

. . 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.

3.1.2.b Terrestrial 3.1. 2.5. 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.
,e ,
y 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 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.

4.0 _Special Surveillance and Study Activities 4.1 Residual Chlorine Surveillance Procram .
ynvironmentalMonitoringRea'sirement The licensee shall sample the station discharge plume in the Susquehanna River to determine the spatial distribution of the total residual chlorine when the licensee initiates a discharge of free available chlorine at the maximum level allowed by the NPDES Permit (i.e., 0.2 mg/l average free residual chlorine or 0.5 mg/l maximum free residual chlorine).
The licensee shall analyze the waters of the plant discharge plume for total
' residual chlorine and shall deter =ine 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 in accordance with the Procedures .
prepared by the licensee in accordance with Section 5.5.
Applicability This special surveillance program shall commence with the initiation of Pl ant chlorine discharge at the maxi =um level allowed by the NPDES Permit.
This special surveillance program shall terminate when the specified isopleths, areas and volumes have been determined for the operating conditions under which the maxi =um chlorination program is conducted.

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, cnd the plant and river discharge flow races. .
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. This program will provide the necessary information to quantify the portions of the Susquehanna River which will experience residual chlorine concentrations in excess of recom= ended levels.

6.0 Special Requirements 6.1 Erosion Control Inspection Environmental Monitoring Recuirements Routine transmission line surveillance shall include examination for evidence of erosion. All areas within the specified corridor right of way showing evidences of abnormal erosion conditions related to transmission activities shall be identified and recorded. Upon identification of specific erosion damaged areas, initiation of corrective actions shall be undertaken and a record in the form of a field log shall be kept indicating the type of action employed and estimation of effective stabilization.
This Special Requirement shall be applicable during normal-transmission line surveillance and shall be conducted no less than once each year in accordance with the Procedures prepared as per Section 5.5.
This surveillance program shall co=mence at initial criticality of Unit 2 upon initiation of normal transmission line surveillance procedures and continue for the life of the station.
Action A su= mary of the field inspection programs and corrective actions taken to control abnormal erosion conditions associated with transmission line maintenance activities shall be reported in accordance with the routine report schedule of Section 5.6.1. Field logs indicating locations of erosion damage and type of actions taken to rectify erosion problem areas 1564 098
~ ,
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.

6.2 Surveillance of Herbicide Applications Environmental Monitoring Requirements The use of herbicides to control undesirable vegetation within the corridor rights of way associated with the station shall conform to the approved use of selected herbicides as registered by the Environmental Protection Agency cnd approved by state authorities and applied as directed by said authorities. Surveillance shall be conducted only during the period of herbicide applications along the corridor right of way associated with the station. Inspections shall t conducted in accordance with the procedures prepared by the licensee as per Section 5.5 and should confirm that restricted areas have not been sprayed, and that accidents such as spills
~
have been documented and cleaned up to the extent practicable.
Applicability This Special Requirement shall be applicable only during applications of herbicides along transmission corridors associated with the station.
This surveillance program shall cocmence at initial criticality of Unit 2 upon initiation of any herbicidal application program and continue for the life of the station.
Action The annual report in accordance with Section 5.6.1 includes a statement as to whether herbicides were used. Resu.1.ts shall contain (as per Table 5. 6-17) but not be limited to: type (s); concentration (s) of active material; rates i564 100 .
.m location; wind conditions of app 11 cation; method and frequency of application; (estimated in miles per hour); and date of application.
Bases In the Supplement to the FES-OL of 1976 (Section 5.6) it was stated that herbicide usage along rights of way will conform to approved uses as registered by the USEPA and authorized by state authorities. The objective of this monitoring program is to determine the type, volume, manner and method of herbicide applications to ensure environmental quality and provide safe reliabic electrical service.
This infor=ation will provide surveillance information to the staff to ensure that herbicide applications conform to current Federal and state regulationsandthereby,minimizee$vironmentalimpactduetorightofway maintenance procedures.
