Refers to the deviation of a result obtained by a particular.
I method from the value accepted as true.
1 l
Aerial Remote Sensing: The measurement or acquisition from aircraft or spacecraft 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.
Annually: Annually is once per calendar year at intervals of twelve calendar months, plus or minus 30 days.
Batch Release: A batch release is the discharge of fluid wastes of a discrete volume.
Calibration:
An i...itrument 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.
Closed Cycle Cooling:
The condenser cooling method in which the circulat-ing water, after passing through cooling towers, is 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 com-bination with ammonia or orginic nitrogen compounds.
Composition Samole: 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 rate discharge at the 4

(2) For certain mixtures of ganma emitters, it may not be possible to measure radionuclides in concentrations near this sensitivity limit when other nuclides are present in the sample in much greater concentrations. Under these circumstances, it will be more appropriate to calculate the concentrations of such radionuclides using measured ratios with those radio-nuclides which are routinely identified and measured.
(3) The detectability limits for radioactivity analysis are based on the technical feasibility and on the potential significance in the environment of the quantities released. For some nuclides, lower detection limits nay be readily achievable and when nuclides are measured below the stated limits, they should also be reported.
(4) The results of these analyses should be used as the basis for recording and reporting the quantities of radioactive material released in liquid effluents during the sampling period.
In estimating releases for a period when analyses were not perfomed, the average of the two adjacent data points spanning this period should be used. Such estimates should be

licensee shall maintain and operate L.,
the equipment installed in the liouid radioactive waste system to reduce the release of radioactive materials in liquid effluents to as low as prac-ticable, consistent with the require-ments of 10CFR 50.36a. Normal use and maintenance of installed equipment in the liquid radioactive system is expected to result in releases of not more than about five curies per radioactive waste-producing reactor per year, excluding tritium and dis-solved gases, during normal operations.
In order to keep releases of radio-active materials as low as practicable, the specification requires, as a min-intrt, operation of equipment whenever the rate of release exceeds 1.25 curies per radioactive waste-producing reactor per quar', excluding tritium and dis-solved v.ses.
In addition to the limiting conditions for operation listed under Specification b., the reporting requirements of Spect-fication e., the requirements of Section 5.6.2, delineate that the licensee shall identify the cause whenever the rate of radioactive effluents, excluding tritium and noble gases, exceeds 2.5 curies per radioactive waste-producing reactor cur-ing any calendar quarter and describe the proposed program of action to re-duce such release rates.

Thermal Characteristics of Cooling Water Discharge Environmental Monitoring Requirement During normal operation of the station, temperatures of the ambient intake water and the discharge from the cooling system to the river shall i

per Section 5.5.
This specification applies to the discharge from out-fall serial number 001, Combined Mechanical Draft Cooling Tower Blowdown as identified in NPDES permit PA-0009920.
This monitoring program shall commence with the initial attainment of normal operation of Unit 2 and continue until approval for termination or modification of this monitoirng requirement is obtained from NRC per Subsection 5.7.1.

3-3 Bases The purposes of this monitoring requirement are to assure that (a) the difference between intake water temperature 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 l
discharged cooling water comply with the requirements of NPDES permit PA-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 offects 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 flow condition, the analysis of thermal effects indicates that the mixed mean receiving water temperature would be increased less than 0.14'C (0.28'F). The analysis also indicates that the thermal plume is expected to he limited to 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 induce calefaction of an excessive portion of the Susquehanna 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 expected to exert significant biological effects on Susquehanna River populations.
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 compatible with the Commonwealth of Pennsylvania water quality require-ments. An NPDES permit has been issued to the licensee providing for this effluent limitation except when the ambient river temperature exceeds 30.5 C (87'F).
The existing NPDES permit also limits any rise in discharge temperature to no more than 2.8*C (5*F) during any one hour.
The NPOES permit further provides for exceptior.s to the 2.8 C (5.0*F) temperature rise limitation by recognizing that for short and infrequent periods during the year the combination of atmospheric conditions and river tempera-ture may occur which causes the MDCT to be incapable of removing sufficient heat to meet the limitation.

3-4 The above monitoring program will provide the informatian needed to determine whether the station is operating in :n environmentally acceptable m
manner and as analyzed its the Supplement to the FES-OL and in staff testimony before the Atomic Safety and Licensing Board." In addition, it will provide input to the programs described in Subsections 3.1.1 and 3.1.2 which are portions of the continuing study of the effect of thermal discharges from the Three Mile Island Station on the water quality and aquatic life in the Susquehanna River. The Special Thermal Plume Mapping study required under Section 4.2 will also use this information as a basic data input.

During normal operation, the contents of the holding tanks for the J
demineralizer and condensato polisher regeneration solutions shall be 5

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 subsequent to issuance of the operating license and shall continue until approval for termination or modification of this moritoring requirement is obtained from NRC per Subsection 5.7.1.
Action The results of this monitoring program shall be summarized, analyzed, interpreted, and reported in accordance with Subsection 5.6.1.
For each release, the license shall record the date of each sample, the pH measured and the method of analysis used.
A nonroutine report shall be submitted in accordance with Subsection 5.6.2.b. if the the pH of the discharges from the holding tanks falls outside the range stipulated by the effluent limitations prescribed by the Commonwealth of Pennsylvania and the U.S. Environmental Protection Agency in the certificates 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 ETS.
Bases This monitoring program will provide necessary information to determine whether the pH of the discnarged demineralizer and condensate polisher regeneration solutions are within the range necessary for the protection of aquatic biota and whether the facility is being operated, 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 Suscuehanna River water quality standards and the FVPCA Steam Electric Generating Point 3
Source Category Effluent Guidelines and Standards, respectively.
The Commonwealth and EPA have determined, through issuance of the licensee of a water quality certification and NPDES permit PA-0009920 (pursuant to
!NPCA Sections 401 and 402, respectively), that these requirements will be mat under proposed operation.
In the Supplement to the FES, Subsection l
5.3.3, the staff, in its analysis, determined that the maintenance of g
regeneration tank discharge pH within the ranges of 6.0 to 9.0 will'not result in unacceptable impact on the receiving water.

analyzed for total residual chlorine utilizing the amperometric titration h
technique in accordance with the Procedures prepared by the license per L.
Section 5.5.
This Environmental Monitoring Requirement shall be applicable under normal station operation.
This monitoring program shall commence with the initial application and discharge of residual chlorine from Unit 2 cooling systems subsequent to issuance of the operating license and continue until approval for termina-tion 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 u. 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 conditions prescribed by the Commonwealth of Pennsylvania and the U.S. Environaental Protection Agency in the 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 systems is permitted by the NPDES Permit with limitations on the concentration of free available chlorine in the station discharge; on the duration of discharge of both free avail-able and total residual chlorine; and on simultaneous discharge of either l
free available or total residual chlorine from both units. Toxicity to e
aquatic biota occurs from both the free and combined available residual j
chlorine fractions. Therefore, a measure of the potential toxicity of y
the station's discharge is the measure of total residual chlorine.
This monitoring program will provide information on the magnitude of the total residual chlorine concentration in the station discharge during plant chlori-p}
nation to determine whether concentrations harmful to other users are present.
An effluent limit for protection of warm water fish species to intermittent chltrine exposure of 0.2 mg/l total residual chlorine has been suggested by Brungs (1973), EPA (Tebo, 1975) and Basch and Truchan (1974).
1490 218_
i
3-8 In Subsection L.3.3 of the Supplement to FES, it was recognized that chlori-nation of station systems at the level permitted by the NPOES Permit could m
lead to discharge 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 often 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 Supplement to the FES-OL, Subsection 5.5.3.
The establishment of the specified nonroutine report requirement will also alert the staff to toxic conditions in the vicinity of the station outfall and to unanticipated operating conditions at the plant.

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 5.5.2.2) determined that impacts to the ichthyoplankton of Lake Frederic may result from the opera-tion of Three Mile Island Nuclear Station. The Atomic Safety and Licensing Board determined in its Initial Decision, dated December 20, 1977, (Page 80 ff.) that the program to monitor the possible impacts to fish should continue for at least three years following the onset of Unit.2 operation.
Impacts may occur due to the entrainment of fish eggs or larvae as a result of mechanical, thermal and biocidal effects. Operational entrainment studies of Unit 1 have indicated low numbers of larval fishes at the intake. Those which have been taken, however, have been represented r
3 by several important forage (shiners and darters) and recreational (catfishes, sunfishes, perch) species.
The densities of larvae were higher at the j
A intake than at the discharge and always higher at njght than during the day for both far-field and entrainment samples.
Fish larvae. have been d
M taken during far-field sampling undertaken at night from April to August,
[
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.

3-16 3.1.2.a.(1)(c) Fish Environmental Monitoring Requirement The ichthyofauna shall be sampled to establish population estimates in specific areas and to detect and assess the significance of changes in species composition, relative abundance, seasonal and spatial distribution, f
condition, and diversity of species as related to power station operation.
All samples shall be collected and all analyses shall be performed in accordance with the Procedures prepared by the licensee per Section 5.5.
The sampling and analytical procedures shall be such that data obtained may be compared and related with that from the program required in Subsection 3.1.2.a.(2).
The program shall provide for sampling of fishes by various methods which will provide meaningful statistics in the forn of catch per-unit-effort. Additionally, creel census shall continue to be performed.
When large numbers of fish are captured which may be in excess of those required for proper analysis, a subsample shall be taken which is represent-ative of the sample as a whole (e.g., by species, size classes, reproductive status). The excess shall be returned.
This monitoring program shall commence at initial attainment of normal operation of Unit 2 and continue for a period of at least three (3) years.
Approval for modification or termination of this monitoring requirement may be obtained from NRC in accordance with Subsection 5.7.1.
Action a
Description of the program, results, and interpretative analyses of environ-mental impacts shall be reported per the routine report schedule of Subsection 5.6.1.
Results reported shall contain information encompassing but not limited to:
sampling date; station number; depth of the sample in meters; sampling gear type used; duration of sampling (minutes); species or taxon; the actual or estimated number of each taxon collected in the sample; length frequencies (numt'er in 5 mm intervals); and mean weight (grams) for all specimens in each length interval.
If a significant deviation from preoperational conditions is discovered, the reasons for the deviation t
shall be determined.

3-17 Bases The environmental assessments made in the FES-OL of 1972 (Section V.C.2)
I and the Supplement to the FES-OL of 1976 (Section 5.2.2.1) determined that s
impacts to the fish populations of Lake Frederic may result from the i
operation of Three Mile Island Nuclear Station because of impingement of adult and juvenile fishes and the entrainment of fish eggs and larvae.
The Atomic Safety and Licensing Board determined in its Initial Decision, dated December 20, 1977, (page 80 ff.) that the program to monitor the possible impacts to fish should continue for at least three years following the onset of Unit 2 operation. This sampling program will be performed to
~
assess the relative significance of these phenomena on the fish populations.
Additionally, several species support an active recreational fishery in Lake Frederic and might be subject to potential impact.
These species are sunfish and catfish (several species each), rock bass, smallmouth bass, walleye, and possibly crappie and carp. Operational impingement studies of Unit I 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 are 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 discharge. 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 disappearing if they approach the limit of their temperature creferendum.
The creel survey conducted during Unit 2 preoperational studies produced results consistent with those from Unit 1 operational studies. A creel survey focuses on the recreational fishery and examines directly the effects of TMI operation on the fishery resource at the point of exploitation. The results to date also indicate some similarities and points of comparison among impingement, far-field fish sampling, and the recreational fishery.
This program will provide information necessary for the evaluation of the effects of TMINS operation on the ichthyofauna of the Susquehanna River.

All samples shall be collected and all analyses shall be performed in accordance with the procedures prepared by the licensee per Section 5.5 of these ETS.
For each sample, the following physical data shall be provided:
number and type of river water pumps operating and their rated capacity; and intake temperature.
This monitoring program shall commence at initial attainment of normal operation of Unit 2 and continue for a period of at least three (3) years.
Approval for modification or termination of this monitoring requirement may be obtained from 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 contain the following information: date of the sample, the taxa collected, the actual or estimated number and weight of each taxon impinged for each sample period, the time averaged volumetric flow rate of Unit 2 cooling water and the average intake water temperature.
A comparison between the impingement experience at Unit 1 versus Unit 2 shall be p*ovided.
Organisms collected from the traveling screens shall be disposed of in a manner consistent with requirements of appropriate Federal, State and Local regulatory agencies and described in the procedures document required by Section 5.5.

3-19 determinable on a theoretical basis alone.
Sampling of organisms collected on the traveling screens will ensure that a reasonable estimate of the y
organisms impinged on the intake structure will be identified and enumerated.
This information when combined with the results of the far field biological i
surveillance program in the intake / receiving waters will provide the empirical basis on which to judge the impact of Unit 2 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 a separate intake structure.
Monitoring of impingement losses will establish the relative u.
efficiencies and total losses associated with the operation of Units 1 and 2.
The Atomic Safety and Licensing Board determined in its Initial Decision, dated December 20, 1977, (page 80 ff.) that the procram to monitor the possible impacts to fish should continue for at leasu three years following the onset of Unit 2 operation.

3-20 3.1.2.a.(3) Entrainment of Ichthycolankton m
Environmental Monitoring Requirement Ichthyoplankton (fish eggs and larvae) shall be collected during the months of April through August at the intake structures to identify taxa and to estimate numbers lost by cooling system entrainment. Gear used in the collection of entrained ichthyoplankton shall be comparable to that used in the General Ecological Survey for far-field monitoring of ichthyoplankton.
g Collections shall be made in accordance with the Procedures prepared by the licensee per Section 5.5.
On each sampling day, collections shall be made so as to identify day-night variation in concentration of organisms.
Specimens shall be identified to the lowest practical taxon. This monitoring program shall commence at initial attainment of normal operation of Unit 2 and continue for a period of at least three (3) years.
Approval for modification or termination of this monitoring requirement may be obtained from the NRC in accordance with Subsection 5.7.1.
Action Results of this program shall be summarized, analyzed, interpret.ed 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), number collected and concentration (number /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. The predominant species in the areas 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. The Atemic Safety and Licensing Board determined in its Initial Decision, dated U
Decenber 20, 1977, (page 80 ff.) that the prograa to monitor the possible impacts on fish should continue for at least three years following the onset of Unit 2 operation.

I Environmental Monitoring Requirement j
Vegetation communitiec ;f the site and vicinity shall be aerially photo-I l graphed annually to detect and assess the significance of damage, or lack I
b thereof, as related to cooling tower drift dispersions.
Photography shall be done by aerial overflight. Aerial photography shall be conducted once g
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 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 a program of low altitude true and false color aerial photography (either color infrared photography or multispectral or multiband photcgraphy) along with the associated on-the-ground verification program.
The scale for full coverage shall be adequate to enable identifica-tion of vegetative damage over relatively small areas of terrain. Some circumstances may warrant inspection of photographs discerning individual trees. Such scale should be in the interval between 1:1000 and 1:10,000 as appropriate 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 lintited to, the first two years of the aerial photographic monitoring program. This surveillance program shall commence at initial attainmer.t of normal operation of Unit 2 and shall be continued for at least two years. At the end of two years the licensee may request modification or termination of this monitoring requirement per Subsection 5.7.1.
Action Description of the program, results, and interpretive analyses of environ-mental impacts shall be reported in accordance with Subsection 5.6.1.
Results reported shall contain information encompassing but not limited to:
sampling date; time of day; film type (s); spectral band (s); and one (1) set of resultant color photographs or color slide transparencies encompassing an area approximately one kilometer (1 kn) from the radius of the Unit 2 tower to be filed with the Office of Nuclear Reactor Regulation.

3-22 Bases r-The environmental assessments, as defined in the FES-OL of 1972 (Section V.C.1.a) and the Supplement to the FES-OL of the 1976 (Sections 5.5.1 and 6.5) determined that impacts to surrounding vegetative communities may result from the operation of Three Mile Island Nuclear Station cooling towers. The Atomic Safety and Licensing Board determined in its Initial Decision, dated December 20, 1977, (page 80 ff.) that the programs to monitor the possible impacts of cooling tower operation should include true and false color aerial p'hotography and the associated on-the-ground verification program, and shall continue for at least two years following the onset of Unit 2 operation.
Impacts may occur due to cooling tower drift deposition causing vegetative stress.
Reconnaissance and aerial photographic inspection of biota in the drift field is a suitable means for detection of possible adverse effects of drift.
Such adverse effects may most often be associated with either episodic high level dosages of chlorine or chronic low level chlorine cosages.
Aerial photography will monitor and record tne presence or absence of vegetative effects due to cooling tower drift deposition.

f 4-1 4.3 Special Studies and Reouirements 4.1 Residual Chlorine Study Program Reouirement The licensee shall sample the station discharge plume in the Susquehanna River to determine the spatial distribution of the total residual chlorine j
when the licensee initiates a planned discharge of free available chlorine 9
I at the maximum level allowed by the NPDES Permit No. PA-0009920 (i.e.,
l 0.2 mg/l average free available chlorine or 0.5 mg/l maximum free available b-chlorine).
The licensee shall analyze the waters of the station's 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 in accordance with the Procedures prepared by the licensee per Section 5.5.
This special study program shall commence 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:
One-unit operation (with maximum chlorination) when the Susquehanna a.
3 River flow rate is less than the median flow rate of 566 m /sec (20,000 cfs).
b.
One-unit operation (with maximum chlorination when the Susquehanna 3
River flow rate is greater than the median flow rate of 566 m /sec (20,000 cfs).
Two-unit operation (with maximum chlorination of one unit) when the c.
Susquehanna River flow rate is less than the median flow rate of 566 m /sec (20,000 cfs).
3 d.
Two-unit operation (with maximum chlorination of one unit) when the Susquehanna River flow rate is greater than the median flow rate of 566 m /sec (20,000 cfs).
3 Action The results of the study conducted under this program shall be summarized,The
}
analyzed, interpreted and reported in accordance with Subsection 5.6.1.
P results shall include the locations of the isopleths, the surface areas E
defined by each, the estimated volume of water within each isopleth, the 3
method of analysis, the date of analysis, and the station's discharge and river flow rates.
1490 247 m
4-2 Bases In the Supplemer.t to the Final Environmental Statement, Subsection 5.3.3, it was recognized that chlorination of station systems at the level permitted h
by the NPDES Permit could lead to discharge of total residual chlorine values
'H up to 3 times the measured values for free available chlorine. These levels would exceed a recognized criterion for exposure of aquatic biota to residual y
chlorine. The Staff analysis indicated that the residual chlorine levels i
in the discharge plume would be reduced to levels below the criterion within j
a short distance of the outfall. This program will provide the necessary
[-
information to identify the portions of the Susquehanna River which will experience residual chlorine concentrations in excess of recommended levels.
I 1490 243
4-3 4.2 Thermal Plume Macoing Recuireinent Surveys shall be made to characterize the thermal plume of TMI for heated water discharges into the Susquehanna River.
The surveys shall be conducted in accordance with Procedures prepared by the licensee per Section 5.5 at least three times per year, during periods when one or both of the following conditions may be expected to occur:
a.
maximum station cooling water discharge temperature, b.
maximum area of thermal discharge plume.
Data shall be collected at locations and depths following a pattern designed to survey and support definition of the thermal structure of the portion of the Susquehanna River affected by operation of the TMINS.
During each survey, measurements of air temperature, wind speed, and wind direction will be taken.
This special study program shall commence with the initiation of cooling system discharges from Unit 2 subsequent to issuance of the operating license and shall be continued for at least two years.
At the end of two years the licensee may request modification or termination per Subsection
- 5. 7.1.
Action The results of the study conducted under this program shall be summarized, analyzed, interpreted and reported in accordance with Subsection 5.6.1.
The results shall include temperatura measurements, measurement locations, station discharge flow rate, the datos of measurement, and any other hydrological and meteorological data used in the analysis.
Bases Subsection 5.5.2.3 of the Supplement to the FES-OL (12/76) determined that the thermal discharge mapping study of Unit 1* demonstrated that relatively little thermal effect on the Susquehanna River results from operation of that Unit. The thermal plume resulting from operation of Unit 2 in addition to Unit 1 should be mapped to verify the FES assessment that operation of the Three Mile Island Nuclear Station will result in acceptable thermal impact on the Susquehanna River.

4-5 4.4 Erosion Control Insoection I
Reauirements Routine transmission line inspection 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, corrective actions shall be initiated and a record in the j
form of a field log shall be kept indicating the type of action employed L_
and its effectiveness.
This Special Requirement shall be applicable during normal transmission line inspection and shall be conducted no less than once each year in accordance with the Procedures prepared by the licensee per Section 5.5.
This inspection program shall commence upon initiation of normal transmission line inspection procedures and continue until approval for modification or termination of this requirement is obtained from the NRC in accordance with Subsection 5.7.1.
Action A summary of the field inspection program and any corrective actions taken to control abnormal erosion conditicns associated with transmission line maintenance activities shall be reported in accordance with the routine report schedule of Subsection 5.6.1.
Field logs indicating locations of erosion damage and type of actions taken to rectify erosion problem areas and estimation of effective stabilization should be kept and be available on the site for a period of two years.
Results reported shall contain information encompassing but not limited to inspection date; and estimated size of erosion problem area, type of stabilization program, date of effective stabilization, as appropriate.
Bases Periodic maintenance activities or severe weather may cause instances along the transmission line corridors where soil or slope stabilization will be e
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 inspection techniques will identify erosion problem areas and coupled with appropriate erosion control steps will ensure that such areas become stabilized.
