The far-field stretches from the mouth of Delaware Bay to Trenton, NJ. The Chesapeake-Delaware Canal (C&D Canal)and lower portions of the Schuykill River are included.Figure 1-3 Illustration of the near-field study area, in the vicinity of Artificial Island. The near-field limits are defined by the "north boundary" (north tip of Artificial Island to the southern tip of Reedy Island) and by the "south boundary" (mouth of Hope Creek, NJ to Liston Point, DE). The intake basin study area is shown close to the Station.Figure 1-4 Locations of long-term and synoptic (survey) observations relative to the Station.Figure II- I Instrument and data systems for Vessel # 1.Figure 11-2 Instrument and data systems for Vessel # 2.3

Finer resolution spacing for the Salem cooling water intake basin.Fiogure 11-4 Schematic of the ADCP mounted to the survey vessel. The ADCP uses four independent beams to sense current velocity.

Acoustic signals are reflected from ambient sound scatterers in the water column; comparison of the emitted acoustic frequency with the backscattered frequency determines the doppler shift, proportional to the relative speed of the. sound scatterers to the ADCP transducers.

The motion of the vessel is subtracted from the current measurements by acoustic "bottom-tracking." The ADCP measures current profiles (one current measurement per 50 cm depth bin) by "range-gating" the backscattered acoustic signal. Trigonometric reduction of the four independent beam measurements produces three (x-y-z) orthogonal current velocity components.

SUMMARY

I. INTRODUCTION Between March and July 1995, Aubrey Consulting.

Inc. (ACE) conducted a large-scale hydrod\iamic survey of the portions of the Delaware Estuary surrounding the Salem Generating Station. The data collected during this period were used to generate a three-dimensional model of flow patterns near the Station. This survey was performed in response to the accumulation of detritus in the cooling water intake systems during the spring of 1994.These data collected in 1995, in addition to providing bathymetric information, have been used for comparison to those portions of the data set, collected by Lawler, Matusky and Skelly Engineers (LMS) for the 1998 Modified Thermal Monitoring Program, that related to physical processes.

This attachment summarizes the data collection program. Details can be found in the complete report issued by Aubrey Consulting, Inc. 1995.L.A. Objectives The Station is located adjacent to the Delaware Estuary (Figure 1-1), and utilizes Estuary water for its service water system (SWS) and circulating water system (CWS). The goal of the study was to produce comprehensive information about the hydrodynamics in the portion of the Estuary surrounding the Station. Especially detailed information was sought in the area near the intake structures and discharge piping where the converging estuarine, tidal, and Station-generated flows create complex hydrodynamic interactions.

Field observations included local observations of wind patterns, tidal elevations, currents, temperature, and conductivity (a surrogate for salinity).

Appropriate data collection techniques were employed, including shipboard measurements, in situ instrument deployment, and real-time data acquisition.

This report summarizes the field methodologies as well as the resulting data files. It details the types of data acquired, the collection intervals, data quality indicators, data transformation procedures, and the formats used to store the data and generate data displays.I.B. Scope Data collection took place within three defined regions:

the far-field, near-field, and the vicinity of the Station. Note that the far-field and near-field designations differ from those used in the 1998 LMS study. The 1995 study being presented here was intended to describe circulation patterns, whereas the 1998 LMS study was focused on thermal.plume transport, and these different objectives led to different study area delineation.

The far-field region contained the entire Estuary from the mouth of the Estuary to Trenton, NJ, including the Chesapeake and Delaware (C&D) Canal and lower portions of the Schuylkill River (Figure 1-2). Rivers and streams that contributed less than 3% total a 14

\Iarch 1freshwater inflow to the Estuary system were not included.

For the far-field re2ion data from other sources such as NOAA and USGS were included in the analysis.The near-field region was defined as an approximately five-mile portion of the Estuary surrounding the Station. Its northern boundary was a line stretching across the Estuarv between the northern tip of the area known as Artificial Island (where Salem is located)and the southern tip of Reedy Island. Its southern boundary stretched from the mouth of Hope Creek, NJ to Liston Point, DE (Figure 1-3).The vicinity of the Station is the region surrounding the Station's intake structures and discharge pipes (Figure 1-3). This was the area for which the greatest detail of hydrodynamic circulation was sought.The sensor systems used to collect data were technologically sophisticated and well-validated.

They included current meters, tide gauges, Acoustic Doppler Current Profilers (ADCPs), salinity and temperature gauges, a fathometer, GPS (Global Positioning System) location devices and real-time atmospheric monitoring systems.Ship-based observations were made during four surveys conducted from April to July 1995. In situ sensors were deployed between March 1995 and July 1995, and real-time acquisition of meteorological and river data continued throughout the project.Figure 1-4 shows the sensor deployment in the vicinity of the Station. Although sensors were deployed from the mouth of the Estuary to the southern end of the C&D Canal. most were centered around the vicinity of the Station.Shipboard measurements included bathymetry, (broadband)

ADCP, Conductivity-Temperature-Depth (CTD) measurements, and GPS-based location determinations fornavigation. Shipboard data collection occurred principally in the near-field and the vicinity of the Station. High-resolution hourly measurements during full tidal cycles (approximately 12.4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months ) were obtained along the north and south boundaries of thenear-field region, along the boundary of the vicinity of the Station, and along a northwest transect from the mouth of the Estuary to the Station.The in situ data collection effort focused on current and tide measurements.

Instrumentation included bottom-mounted current meters, high-resolution tide gauges, and real-time current monitors.In situ current meters and tide gauges were deployed on each side of the Estuary at both the north and south boundaries of the near-field region.

In situ observations were begun in late March 1995 while Eastern Standard Time (EST)was in effect. The shipboard surveys were performed from April to June, after the shift to Eastern Daylight Time (EDT). The time standard in effect at data collection was retained in the raw data to reduce confusion.

When two data sets were compared, all times were converted to EST. Data collection methods are described in greater detail below.15

-'.M rh i', -11. SHIPBOARD DATA COLLECTION Four ship-based surveys were conducted during the spring and early summer, between 10 April and 23 June 1995 (Table 11-1). Current, temperature.

and salinity profiles were collected along the north and south boundaries of the near-field region as well as within the vicinity of the Station. Bathymetry information was collected throughout the near-field region.Two vessels were employed. Vessel I was a shallow-draft, 22-foot vessel, equipped with a fathometer and CTD profiler and Vessel 2 was a 25-foot Parker, equipped with an ADCP and CTD profiler.Both vessels carried GPS-based navigation systems to pinpoint positions of the acquired data. Instrument system schematics for the two vessels are shown in Figures I-I and [1-2.Vessel 1 was designated a roving data collection platform, and fitted for specialized monitoring.

It was used to generate a high-resolution bathymetry survey of the near-field region during the first survey period (Survey 1). Vessel 1 also was used to measure temperature and conductivity (CTD) profiles at the mouth of the Estuary during a complete tidal cycle to determine levels of salinity entering the system from the open ocean. In addition, the vessel was used to measure salinity levels from the mouth of the bay to the Station and back, to characterize the effects of vertical interactions as ocean tides meet the fresher water discharged from the Estuary during the early spring. These specialized surveys were performed only once.

CTD data were also collected aboard Vessel 1 in surveys conducted simultaneously with Vessel 2 along the near-field boundaries. During these surveys Vessel I traversed the northern boundary while Vessel 2 traversed the southern boundary.Vessel 2 was designated for the regular monitoring of currents, temperature, and conductivity along the northern boundary of the near-field, the southern boundary of the near-field, and in the vicinity of the Station..Each boundary was surveyed throughout an entire tidal cycle. For instance, the firstsurvey day focused on the northern boundary region. The following day, the southern boundary was monitored.

The third and fourth days centered on the vicinity of the.Station. The fifth day was reserved for completing observations that were missed earlier because of weather and/or technical difficulties.

To assure data consistency, the following procedures were adopted. Each survey line was always traversed in the same direction.

The north boundary transect extended from the New Jersey shore at the northern tip of Artificial Island to the southern shore of ReedyIsland, DE, and was always traversed from New Jersey to Delaware. The south boundary line stretched from the mouth of Hope Creek, NJ, to the Delaware shore near ListonPoint. That line was always traversed from Delaware to New Jersey. North boundary transects, repeated hourly, were completed in approximately 25 minutes. Due to greaterlength, south boundary transects, repeated every 1.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months , were completed in approximately 50 minutes. For the vicinity of the Station region, the outside boundary 16 took approximately 45 minutes to traverse and the inner boundary (parallel to the Station's cooling water intake sea\vall) took approximately 5 minutes. Both transects in the vicinity of the Station were repeated every 1.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months . During their return to the transect origin. the vessels conducted CTD profiling (see Section HIC).In order to accurately determine spatial variations in the Estuary's flow patterns, it was essential to obtain precise and accurate positioning information for every piece of data recorded on each vessel. For this purpose, an integrated navigation system was utilized.At the core of the navigzation system was a HYPACK. software package [Version 2](Coastal Oceanographics, Inc., Middletown, CT) installed on a portable 486 laptop computer. This software displays real-time differential GPS positioning information.

[n addition, it assists with transect line design, horizontal datum choice, choice of data sampling rates, and graphical displays.Fundamental to the resulting survey quality is the understanding of the horizontal datum used for positioning.

All surveys were conducted using the World Geodetic Survey 1984 (WGS-84) horizontal datum as the baseline reference (expressed in U.S. survey feet).The Universal TransMercator (UTM) projection was used to generate x-y pairs from latitude/longitude pairs. Digitized maps of the survey area were input and displayed on the computer screen. Survey lines were then developed, either by the HYPACKsoftware as start/end points identified on the digitized map, or manually entered as latitude/longitude pairs.The majority of GPS and other marine devices share electronic information using the National Marine Electronic Association's interfacing standards (NMEA-0183).

The HYPACK software automated the entry of requisite NMEA-0 183 transfer codes and specifications assuring uninterrupted and accurate data transfers.

Typically an RS-232serial line was used for inter-device communications.

The GPS device used in this study was a Northstar 941X with differential beacon receiver (Northstar Technologies; Acton, MA). Technical specifications for the unit are listed in Postscript AA. During these surveys, GPS data were updated to the computer every two seconds. GPS satellite signals are broadcast by the Defense Department with a built-in dither designed to purposely degrade the accuracy and repeatability of positioning information.

To address this, differential corrections are broadcast over radio frequencies from towers built along the coastline.

Positions recorded with differential corrections are accurate to within 20 feet 95% of the time; without differential corrections, accuracies are on the order of 300 feet. Radio reception can be reduced by atmospheric static (e.g., thunderstorms) or physical obstructions.

During the Estuary surveys, differential reception and, hence, positioning accuracy was occasionally lost for periods ranging from five seconds to several minutes. These losses were manifested as "differential jumps" in the transect tracklines.

Such "jumps" were edited from the records during post-processing.

In addition to pinpointing data locations, the GPS navigation system helped keep the survey vessels on course. As the vessel moved across the estuary, the cursor moved in 17 real time across the digitized map on the computer screen. Slight deviations from the transect line could be corrected immediately.

The GPS data were uploaded to both the HYPACK3 PC and the ADCP laptop PC (see Section II.B.2). Navigation data uploaded to the HYPACK computer were stored in raw data files containing time, latitude, longitude, and x-y position pairs. The raw data were stored in ASCII format.

The header described the survey parameters (e.g., data, surveyor, devices used). Succeeding data rows were preceded by a data type identifier:

RAW for latitude/longitude pairs. POS for x-y positioning pairs, ECI for echosounder data (if used), T ID for tide data (if used), and FIX for event mark. The computer clock time was included for each data event.During post-processing, ACI combined the x-y position pairs with time data and, ifavailable, depth measurements. File-naming conventions were developed and applied automatically to both raw and processed data files. The raw file convention was as follows: (transect line number)(start time)(vessel)(survey) (day). For example, raw data file 001 _ 1642.114 references data from transect line 001 begun at 1642 (4:42 PM) by Vessel 1, during Survey I, day 4.In the following Sections, references to navigation log (*.LOG) files refer to the daily list of HYPACK raw navigation data files generated for a specific survey day. The processed navigation files (x-y-time) were named according to conventions developed for the ADCP (see Section II.C.4.a).

Specifically (Navigation Files Prefix) (Survey) (day)(transect line number) DAT. Thus NAV2201 IDAT references the processed navigation file (NAV) for Survey 2, day 2 (22), conducted along transect line number I 1' (011). The.DAT suffix indicates this is a datafile.II.A. Bathymetry A bathymetric survey was performed to measure depths in the near-field region between 10 and 12 April 1995 during Survey 1, using a vessel-mounted Si-Tex AVS-106 fathometer (Si-Tex Marine Electronics; St. Petersburg, FL). The system is capable ofsurveying depths as shallow as 2.0 feet with 0.10 foot resolution.

Fathometer data were uploaded to the HYPACK system and combined with GPS positioning informationevery 4.6 seconds. Specifications for the Si-Tex fathometer are listed in Postscript A.Vessel 1 was fitted for high-precision bathymetric measurements in both the deeper and shallower areas of the Estuary.The bathymetric survey consisted of survey lines every quarter mile, running from west to east across the Estuary. These survey lines were approximately five miles long and extended from the north near-field boundary to the south near-field boundary.

Inaddition, detailed bathymetry data were collected around Alloway Creek, Augustine Creek, Appoquinimink River, Blackbird Creek, and Hope Creek Jetty (Figure 11-3).On 14 April 1995, a high-resolution precision survey measured depths in the vicinity of the Station. Survey lines were spaced 50 feet apart with the southern portion of the line extending 300 feet beyond the intake location and the northern portion extending 300 feet 8 18

-4 \i jr I-beyond the discharge location.

A survey of Sunken Ships Cove was combined with the survey of the vicinity of the Station, with lines spaced 100 feet apart and overlapping those for the vicinity of the Station survey.ll.B. Acoustic Doppler Current Profiling The recion of the Estuary surrounding the Station has intricate flow and circulation patterns resulting from both its natural geography and the proximity of large manmade obstructions (Sunken Ships Cove and Hope Creek Jetty).

Because single-point current measurements would be inadequate, an acoustic Doppler current profiler (ADCP) was mounted aboard Vessel 2 to augment current observations and enhance understanding of Estuary geo aphy. Vessel 2 recorded ADCP measurements while regularly traversing predefined sections of the Estuary at 60- or 90-minute intervals during complete tidal cycles of 12.42 hours4.861111e-4 days 0.0117 hours 6.944444e-5 weeks 1.5981e-5 months . The resulting current measurements were used in concert with data from the moored current meters to analyze flow patterns in the vicinity of the Station.II.B.I. Instrument

System Description

An ADCP measures current flow by comparing high-frequency acoustic signals transmitted through the water column with the returned signal (backscattered echo). A single-frequency pulse (in this study, 1200 kHz) is emitted from a transducer at the surface. As the signal moves through the water column, it is reflected back toward the transducer by ambient scattering materials such as plankton, suspended particles, bubbles, etc. travelling through the water at the same speed as the current. The frequency of the reflected acoustic signal is compared to the frequency of the emitted signal, and the difference in frequencies (the Doppler shift) is directly proportional to the relative speed at which the scattering materials (thus, the current) are moving either toward or away from the transducer (Figure 11-4).The 1200 kHz ADCP employed in the survey was manufactured by RD Instruments (RDI) of San Diego, California

[Model #BB DR1200]. The instrument consisted of four transducers placed 90 degrees apart in the horizontal plane and directed 20 degrees from the vertical axis. The ADCP profiled the entire water column by obtaining multiple independent measurements of water velocity at varying depths from the transducer.

The ADCP processes the backscatter echo frequency for each transducer, developing four independent velocity measurements.

These independent velocities are then trigonometrically transformed to produce three orthogonal velocity vectors: two horizontal and one vertical for this calculation.

Because only three beams are required for this calculation, the fourth beam is used to check data quality.Depth profiles are obtained by "range-gating" the backscattered pulse, i.e., by turning the receiver on and off (gating) at regular intervals after the original pulse is emitted. Gating the return echoes creates discrete sections of the water column called depth bins. The duration of the on-off sequencing will determine the size or range of each depth bin.Typically, a 1200 klz ADCP can measure current speeds in depth bins as small as 25 centimeters.

For this program, depth bins were set at 50 centimeters.

As a result, three velocity vectors were measured for every 50-centimeter increment of the water column.19 1However.

practical limitations (e.g., interference at both the transducer site and at the bottom) mean that accurate velocities can only be obtained starting a minimum of50 centimeters from the transducer and ending 50 centimeters above the bottom.The ADCP measures water velocity relative to the transducer.

For a shipboard-mounted ADCP. the velocity of the transducer must be subtracted from the water velocity measurements.

This is accomplished by using the Doppler shift principle to measure the velocity of the transducer relative to the bottom. Interleaving water track pulses with bottom track pulses allows the instrument to accurately measure current velocities independent of the motion of the transducer.

The effectsof incidental vessel motions, such as pitching and rolling in surface waves, are addressed by using an internal compass and tilt sensors.Accuracy depends primarily on the size of the depth bin. The larger the depth bin (i.e., the longer the receiver gate remains open), the longer, the echo record used to calculate the Doppler frequency shift and the more likely velocity measurements will approximatethe true flow. Accuracy is also enhanced by the averaging of several successive single pulses, termed an ensemble. For the surveys in the Estuary, each ensemble consisted of five water track pulses and four bottom track pulses emitted over a 4- to 4.5-second period. The standard deviations of the current measurements are also indicative of the ADCP accuracy.

Large depth bins and multiple pulse ensembles reduce variability in the data and thus reduce standard deviations. For this study, standard deviations of current measurements were on the order of 2-3 cm/sec. More information on ADCP operation is*contained in Postscript B.IL.B.2. Data Collection TechniquesThe ADCP was mounted to the stem of Vessel 2 on a rigid bracket. The instrument was directed downward, with the transducers approximately 25 centimeters below the water surface. Data and power were transferred from a deck unit installed within, the vessel cabin. Power was supplied at 110 VAC from a portable generator.

The instrument system schematic is depicted in Figure 11-5. A laptop PC controlled data sampling configurations (e.g., depth bin size, ensemble averaging, water track and bottom track modes), instrument testing and initialization, and the start/stop of data logging.Differential GPS data were logged directly through a serial port on the ADCP PC and saved as separate files independent of HYPACK navigation data. Latitude/longitude pairs were logged together with ADCP ensemble number and computer clock time (in number of seconds after midnight; for example, 12:00 noon appeared as 43200). Due to ease of use, the HYPACK -generated navigation (x-y-time) files were used for primary positioning information, while the ADCP-generated navigation (latitude-longitude-time) files were used for positioning quality control.The current data for each ensemble (depth bin location, east and north components of velocity, vertical velocity, error velocity, speed, and magnitude) along with instrument-related information (individual beam echo intensities, water temperature, instrument time, tilt, heading and water depth) were stored in binary format in the raw data files.3 20

11. B.3. File-Naming Conventions The automatic file-naming convention for the ADCP data was as follows: (survey number)(surv,.ey day)(transect line number)( file type code).(file-size suffix). The First three characters denote the survey number; for example. Survey 4 was SV4. The fourth character represents the survey day (I through 5). Thus SV 1 would represent the first day of the first survey Transect line numbers are shown in the next three characters.

Each day's transects were numbered sequentially (001, 002, etc.) and automatically updated each time the file was opened. On occasion, files were opened and, for various logistical reasons, closed immediately, resulting in a gap in the sequential order of line numbers. No ADCP transect data were lost because of such numbering gaps.The file type identifier is the last character file name. An "R" denotes a raw data file. An"N" denotes a navigation file.The file-name extension indicates the size of the file. Due to the large volume of data generated during each transect, when files exceeded 200 kilobytes, data were rolled over into another data file. The first 200 kbytes of data are labeled with a .000 suffix; the second 200 kbytes of data are labeled with a .001 suffix. The file rollover was seamless, meaning no data were lost. This feature eased data handling by breaking data files into smaller, more manageable blocks.As examples," File SV44005R.000 contains the first 200 kbytes of raw ADCP current data (R.000), collected on Survey 4, day 4 (SV44), during the transect of line number 5 (005)." File SV1501ON.001 contains the second 200 kbytes of ADCP navigation data (N.00I)collected on Survey 1, day 5 (SV 15) during the transect of line number 10 (010).I.B.4. ADCP Data Processing ADCP data were processed for Survey 1, day 4; Survey 2, days 2, 3, and 4; Survey 3, day 2; and Survey 4, days 2, 4, and 5 (Table 11-2). These were the only days that data collection spanned the complete 12.4 hour4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months tidal cycle. Post-processing of the ADCP data was accomplished using BBLIST (RDI Instruments) and MATLABD [Version 4.2] a software package by MathWorks, Inc. (Natick, MA).. MATLABO files (or .mfiles) were used to create current direction/velocity vectors and color plots of the data (see Section 1I.B.5).nI.B. 4.a. Step One: Data Reformatting In order to be readable by the MATLAB' program, the raw ADCP data had to be converted from binary to ASCII format. The volume of information contained in the raw files was enormous, much of it, such as instrument settings, secondary to current observations.

ACI used the RDI program, BBLIST, to customize the ASCII output. Three different ASCII output formats were created to meet different analytic and display requirements.

21 In each format, data fields are identified by the ensemble number followed by the required information.

In the first format, raw ADCP data generated on the north and south boundaries were reformatted to include ensemble number, Julian day (the calendar day numbered sequentially from January 13'; e.g., February 23 rd would be Julian day 54), and water temperature. along with depth profiles of east and north current velocitycomponents, current speed, and current direction.

One data field was created for every recorded ensemble.

Each field consisted of 31 lines of data.The first line contains 3 data values: ensemble number, time in decimal Julian days (theJulian day is numbered consecutively from January 1 S' and the decimal shows the time as a fraction of 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ; thus, April 11 at 15:12:32.5 EDT is decimal Julian day 101.6337 1), and water temperature in degrees C. The next 30 lines represent current measurements at each depth bin. The first column of lines 2 through 31 represents the center depth (in meters) of each depth bin. The top bin corresponds to a volume of water 1.5 meters to 2.0 meters from the surface and is represented as 1.75 meters. The bottom-most depth bin represents a volume of water 16.0 meters to 16.5 meters and is represented as 16.25 meters. The second through fourth columns represent east components of current velocity, north components of current velocity, and current speed, all in cmisec. The fifth column indicates current direction, measured in degrees from due north.Data lines 32 through 63 represent data corresponding to the second ensemble of the data file, and so on to the end of the file. No headers appear in the data file to identify the data field. Table 11-3 shows an example of a single data field representing data for ensemble number 112 taken on Julian day 101.63371 (11 April 1995 at 15:12:32.5 EDT).Estuary u.,,hs in the survey areas never exceeded 14.0 meters. Hence, a depth threshold for range-gating was set at 16.5 meters (i.e., the instrument wouldn't listen for returns beyond 16.5 meters), to assure the ADCP would always range to the bottom. Data below the actual bottom are set at 9999.0 and are eliminated during data processing.

Data generated along the vicinity of the Station boundary were displayed as vectors (arrows) representing speed (length of the arrow) and direction (direction of the arrow).Because these data took a different form in the display, the data were formatted slightly differently.

The first line included ensemble number, decimal Julian day, water temperature in degrees C, followed by four data values representing the depths of each of the transducer beams. Because the beams were angled 20 degrees from the vertical, and bottom topography varied, each beam measured a slightly different depth. An average of the four beam depths was calculated as the ensemble (or average) depth.Lines 2-31 again reference depth profile measurements.

The column identifiers are depth bin, east velocity, north velocity, speed, direction, error velocity, and "percent good".Error velocity and percent good are data quality indicators.

Error velocity is calculated 3 22 using the redundant fourth transducer beam. companrng velocity measurements between different beam combinations. Percent good indicates thle number of pulses that used all Four beams to calculate accurate velocities (as opposed to the three required).

Percentcood values are generally 100, except near the bottom where some pulses became contaminated by bottom interference.

Values of 60% or 4 0% (meaning 3 out of 5 or 2 out of 5 water track pulses used 4-beam solutions) are common in near-bottom bins. If percent good values fell below 80% then the data were ignored.The third ASCII output format was designed to verify the data quality. Included werequality indicators such as beam echo strengths, pulse-to-pulse correlation magnitude, error velocities (based on the redundant fourth transducer beam measurements), and statistical indicators.

Si-nificant variations in data can result from both true Estuary behavior or frommeasurement inaccuracies due, for example, to excessive surface vessel motion, wake near the transducer at high vessel speeds, or acoustic contamination from nearby electronic instruments. Evaluating error velocities concurrently with observed current velocities will help distinguish between real variability and measurement error. Simply put, if error velocities are within two calculated standard deviations, the observations are good. If error velocities lie outside two standard deviations, the measurements are most likely contaminated by external factors.The following are file-naming conventions and examples of reformatted ADCP data files.(Survey)(day)(transect line)(ADCP site). DAT Thus file SV44005A.DAT contains reformatted ADCP data (.DAT) from Survey 4, day 4 (SV44) collected during the transect of line 5 (005) at either the north or south boundary of the near-field (A is used for both boundaries).

Similarly, the reformatted file SV 14004B.DAT contains ADCP data collected during Survey 1, day 4 (SV14) during the transect of line 4 (004) at the basin site (B).I1.B.4.b.

Step Two: Merging Acoustic Doppler Current Profiler and Navigation Data As noted above, the HYPACK generated navigation data proved easier to use than the ADCP-recorded information.

Not only were the HYPACK x-y pairs numerically simpler than the ADCP-generated latitude/longitude pairs, but the HYPACK-generated data were formatted in columns, whereas the ADCP navigation file format usedirregularly spaced rows, that made using the data more difficult.

A time-stamping method was used to match each ensemble with a specific x-y positionpair. This method assumes that both the ADCP system clock and the HYPACK system clock were synchronized perfectly throughout the survey. This was not always the case, because there was an offset between the two clocks which varied from day to day primarily due to inherent delays in the ADCP time command. Time differences between the two system clocks were as small as two seconds and as great as 90 seconds. To avoid 23

<!\h3t f!- -'difficulties during post-processing, time differences were monitored and documented manually several times during the survey.The times were also synchronized by simultaneously sending a GPS signal to both the ADCP and HYPACKt computers at the beginning and end of.each survey. The clocktimes assigned by each computer system to the test GPS position were compared, and appropriate time corrections were applied to that survey's data. Once times were corrected and synchronized.

each ADCP ensemble (ensembles were separated by 4-4.5 seconds) was merged with the closest HYPACKO time data (where each x-y pair was separated by 2 seconds).fI B. 4.c. Step Three: Data Transformation The along- and cross-river components of velocity usually represent more accurately the structure of water currents, particularly in rivers or estuaries that are not strictly oriented in a north-south/east-west direction.

The data were therefore transformed from an earth-based (east and north) coordinate system to a locally based (upstream and cross-stream) coordinate system. Currents moving upstream (i.e., when the tide floods the Estuary)were characterized as positive, ebbing currents (i.e., flowing toward the mouth of the Estuary) were deemed negative.

Positive cross-stream currents flowed toward New Jersey from the Delaware shore. Long-term current measurements are described in detail in Section III.B.Cross-river transects on the north and south boundaries contained noise, i.e., high-frequency variability from one ensemble to the next, which sometimes obscured subtle variations in Estuary currents.

This was addressed using a moving triangular filter applied across all data values.The filter took the first seven values and weighted the center (fourth) value at 100% of its full value, adjacent values (third and fifth) at 75%, twice-removed values (second and sixth) at 50%, and thrice removed values (first and seventh) at 25%. The values they obtained were then summed and divided by four, in order to obtain a weighted average for these seven values. The same process was then carried out for the second through eighth values, and so on for the remainder of the data set.The filter was applied to all ADCP current ensembles.

The filter extended approximately 100-130 feet on each side of the central data value. The filter reduced the effect of small-scale physical oscillations of the current on the displayed data, bringing the large-scale characteristics of Estuary flow into clearer focus.Two types of spatial averaging also were performed.

The first consisted of reducing the current profiles to a limited number of vectors, in order to reveal the general structure of Estuary flow. Eleven points were defined on each of the north and south near-field boundaries, and a single current velocity was calculated for each point. To do this, several hundred ADCP ensembles were averaged both vertically and horizontally.

The vertical average for the water column at a given location was the average of all current measurements at each of its depth bins.. The horizontal average was performed by breaking the transect into 11 blocks, each consisting of all the ensemble positions within* 24

.4 \iu.-t j!l-it. The number of ensembles assigned to each block varied by transect.

This procedure resulted in one spatially-averaged current vector for each of the 22 points.The second averaging scheme was used to visualize more clearly vertical variations in flow. Current profiles along the vicinity of the Station grid were reduced to five vertical layers. No horizontal averaging was performed, that is, all ensembles were represented.

First, total water depth was established by averaging the four individual beam depths.

The top layer was defined as data values within thefirst 12.5% of depth, the second layer was between 12.5% and 37.5% of the total depth, the third (or middle) laver 37.5% to 62.5% of the depth, the fourth layer was from 62.5%

to 87.5%, and the bottom layer was From 87.5% to 100% of the total water depth.For shallow areas, for example. Sunken Ships Cove, where depths are 5-7 feet, only one to two valid depth bins were recorded.

In such areas, only the top and bottom layers were used. If three or four valid depth bins were available, the top, middle (average of the second and third valid data points), and bottom layers were presented.

Valid bins numbering five or more were averaged as described above.The results of this layering approach were plotted as colored arrows originating at a known x-y location.

The plots illustrate the vertical variation of current in areas in the vicinity of the Station.1.B.5.

The plots represent flow through a cross section of the Estuary. A color scale represents the speed of the current in cm/sec. Estuarine flow is running upstream at 0800 (yellow/orange).

When the velocity is negative (blue), as it is at 1400, the currents are running downstream.

II.C. Conductivity, Temperature, and Depth Measurements Conductivity, temperature, and depth (CTD) data were required to map the spatial and temporal distribution of salinity and temperature throughout the Estuary.I. C. 1. System Description Salinity and temperature profiles were measured using a Micro-CTD manufactured byFalmouth Scientific, Inc. (FSI, Cataumet, MA). The unit measures conductivity, from which salinity is inferred.

An inductive cell allows the free flow of water through the 25 sensing element, reducing the response delays and electrode fouling problems characteristic of traditional conductivity sensors. Temperature was measured using a highly accurate platinum resistance thermometer

(+0.005°C).

Depth was measured by atitanium strain gauge pressure sensor (0-200 dbar range with an accuracy of +/-0.15% full scale). The unit was self-contained and used replaceable battery packs. An internal memory module held I megabyte of data. The electronics were housed in a Delrin (plastic) pressure case protected by a stainless steel cage.

Specifications for the FSI Micro-CTD are shown in Postscript C.A laptop PC fitted with FSI software and a generic terminal emulator controlled communications to and from the instrument.

[I.C.2. Data Collection The CTD data were collected aboard both survey vessels. Vessel 1 tracked from the mouth of the Estuary to the Station on 19 June 1995, measuring CTD profiles at 20 locations spaced approximately one mile apart. CTD profiles were obtained at four sites at the mouth of the Estuary during a single tidal cycle on 20 June 1995. Vessel I also monitored foursites along the southern near-field boundary (S1, S2, S3, and S4) during a full tidal cycle on 27 April and 22 June 1995 (Figure 11-24).On the same two days Vessel 2 simultaneously measured CTD profiles at four sites along the north near-field boundary (NI, N2, N3, and N4). Measurements by the two vessels were synchronized and were obtained at evenly spaced time intervals throughout themonitoring period.

For example, on 27 April 1995 profiles were performed at the N4 site (Vessel 2) and S4 site (Vessel 1) at 10:23 AM, at N3 and S3 at 10:33AM, N2 and S2 at 10:42AM, and NI and SI at 10:5 1AM. Approximately

1.5 hour5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months s

elapsed before the sequence was repeated.In addition, Vessel 2 measured CTD profiles at two sites (BN, BS) in the vicinity of theStation over full tidal cycles on 25 April and 20 June 1995. Each CTD measurement, or CTD cast, was performed manually.

The instrument was toggled on, allowed a one-minute wake-up delay, and lowered through the water column. Local time and water depth were recorded in the survey notes for each cast. The unit was then lifted from the bottom and pulled aboard where the switch was toggled off. Each cast took approximately two minutes. The vessel proceeded to the next site to repeat the sequence.A raw data file was produced each survey day, containing information from all the CTD casts performed on that day. The raw files have a common RAW suffix.

Each cast was separated in the raw data file by a double row of zeros, resulting from the on/off toggle of the instrument switch.The raw data files are formatted by data type and sample number. There are four columns in each file: conductivity (mmho/cm) in column 1 followed by temperature

(°C), depth (meters), and date and time of the sample. Each row of data corresponds to a single sample. The sample rate was set at 2 kHz, meaning two samples of conductivity, temperature, depth, and date and time were written to memory every second while the 26

.1 instrument was submerged.

The time and depth of each cast were compared to logged time and hydrostatic pressure as a way of checking data quality.IL C.3. Conductivity/Temperature/Depth Data Processing Post-processing of the CTD data involved splitting the raw data file into individual casts, using the FSALSOP program from FSI. FSALSOP used the conductivity data tocalculate salinity values. Salinity was referenced to units of the Practical Salinity Scale (1978) (PSU-78).

In addition. FSALSOP reformatted the individual data files into seven columns (scan number, conductivity, temperature, depth, date and time, salinity, and speed of sound).In the FSALSOP-processed output files each individual cast assumed the prefix of the raw file and acquired a new suffix reflecting the order in which the casts occurred.

For example, the first cast was given an .000 suffix, the second .001, etc. If 40 individual casts were performed during a day and logged in the raw data file CTDCASTS.R.AW, 40individual data files would be created by FSALSOP named CTDCASTS.000 through CTDCASTS.039.

MATLAB R was used to develop a program, CTDSPLIT.M, to split each individual CTD cast into upcast and downcast portions. Typically, oceanographers utilize only downcast data when analyzing CTD information.

This is because relatively undisturbed water is measured during the downcast.

However, passing an instrument down and up through the water column induces sufficient mixing to contaminate the upcast reading. CTDSPLIT discarded the upcast data and saved only the downcast data in individual data files.The naming system for these split downcast files was as follows: (boundary location)(site number)(data type)(cast number).(date).

For example, file NICTD6.427 contains data from the sixth CTD cast (CTD6) conducted at site 1 on the north boundary of the near-field region (Ni). The suffix shows that the data were collected on 27 April 1995 (.427).Similarly, file BNCTD4.424 contains data from the fourth CTD cast (CTD4) conducted north of the vicinity of the Station (BN) on 24 April 1995 (.424).II.C.4. Sample Plots Color time series plots showing salinity and temperature variations at the south and north CTD sites in the vicinity of the Station (BS, BN) on 24 April 1995 are presented in Figures 11-25 through 11-28. The color plots show the range of salinity and temperatureover time (bottom horizontal axis).and in relation to depth (left vertical axis).

A 7-hour period is shown representing the variation in values with the tidal cycle.Each plot shows cross-river variations in salinity measured during a single transect.

The plots present a cross-section of the Estuary with Delaware on the left and New Jersey on the right. These cross-sections are considered approximations because only four CTD casts were used to calculate the salinity contours.

27 Figures 11-29 through [1-32 show hourly cross-river salinity variations at the south and north boundaries of the near-field region on 27 April 1995. Tide elevation changes for the day are included at the top of the page. All times are referenced to EDT.Figures 11-33 through [1-36 depict color time series of salinity and temperature variations on 20 June 1995 at the north and south sites in the vicinity of the Station (BS, BN). The plots are similar to those described in Figures 11-25 through 11-28. Comparison of the two groups of figures illustrates seasonal variations in salinity and temperature.

Figures 11-37 through 11-39 show salinity variations at a cross-section of the mouth of theEstuary on 20 June 1995. Eleven time steps are shown. These figures were included to indicate salinity of ocean waters entering the estuarine system. Little variation is noted.Cross-stream variations in salinity are presented for the south and north boundaries of thenear-field region on 22 June 1995 in Figures 11-40 through 11-43. Again, these plots illustrate seasonal differences in salinity levels when compared to Figures 11-29 through 11-32. Tide elevations for 22 June 1995 are also shown. All times are EDT.III. LONG-TERM MOORINGS Long-term observations of tides and currents are essential for understanding hydrodynamic processes.

For this study, in situ instruments were deployed at sites near the Station for the long-term measurement of currents, tides, temperatures, and salinities in the study area. Data collection efforts began during the last week of March 1995 and lasted until the end of June 1995.III.A. Tide Measurements III.A.1. System Description Four tide observation gauges were placed at each corner of the near-field boundaries (Figure II1-1). Station NNJ was at the northern tip of Artificial Island, Station NDEL was at Augustine Beach on the Delaware shore, Station SNJ was at the mouth of Hope Creek, and Station SDEL was near Liston Point, Delaware.

A fifth gauge was deployed on the Chesapeake Bay side of the C&D Canal in Town Point Neck, MD. Specifications and deployment dates are shown in Table 111-1.Each station consisted of an SP2200 wave/tide gauge manufactured by Woods Hole Instrument Systems, Ltd (WHISL; Cataumet, MA). The instrument features a ParoScientific (Paros) Digiquartz pressure sensor with a resolution of 1 mm water and accuracy of 1 cm. Water temperatures were measured simultaneously with a Parostemperature sensor of resolution of 0.01°C and an accuracy of +/-+0.1C. Technical specifications for the SP2200 are presented in Postscript D.The instrument is self-contained.

For the sampling rates chosen, battery life was estimated at three months with one Mbyte of available memory.

The unit was housed in a sealed plastic pressure case and attached to an aluminum pipe. Pipes were installed in the Estuary bottom using an hydraulic pump.

328 Water elevations were sampled as a 7.5-minute continuous average. Values were continuously summed over the 7.5 minutes and a single mean water elevation value was recorded for that interval. There were a total of 192 data points for each day water elevation was measured.Data recovery involved dispatching a vessel to the gauge location to remove the instrument physically from the pipe mooring, leaving the mooring in place. The instruments were first returned to shore in early May, where the preceding six weeks of monitoring data were uploaded to the PC hard disk.Data integrity checks were performed, fresh batteries were supplied, the memory was reinitialized, and the unit was sealed for re-deployment.

The gauges were returned to their moorings the following day. The gauges then recorded continuously until final recovery in late June 1995. All gauges returned 100% of the intended data.Small differences in along- and cross-river water elevation can result in potentially large differences in flows. To address this, the absolute elevation of each gauge was surveyed using a known vertical datum prior to recovery.

Surveys were conducted by Taylor, Wiseman, and Taylor (Mt. Laurel, NJ).

Kinematic GPS methods were used to verify that the instrument functioned within the specified sensor accuracies (1 cm). A GPS antenna was attached to the pipe mooring for a selected period, typically 40 minutes. The distance from the pressure sensor port to the antenna was measured manually.

The kinematic GPS system collected satellite information during the measurement interval and averaged the x, y, and z values to obtain a (relatively) long-period mean value.

Using these data, the water elevation data from the four SP2200s were adjusted to the North 0 American Vertical Datum 1988 (NAVD88).

This survey was repeated in June 1995 to adjust for possible vertical displacement of the instrument mountings during recovery and deployment.

III.A.2. Data Processing Uploaded water elevation data were transferred in hexadecimal format for processing and analysis.

Data fields included water elevation (meters), temperature

(°C), date and time, and instrument-related engineering records.Raw data files were labeled according to the instrument identifier (usually the serial number), date of recovery (AP for April 1995, JU for June 1995) followed by a RAW suffix. For example, data recovered from the tide gauge deployed at the northern tip of Artificial Island (Station NNJ, serial number 52019) during the first deployment period was labeled 52019AXP.RAW.

Software was used to extract water elevation (in pounds per square inch [psi]), water temperature (in degrees Celsius), and date and time of each measurement from the raw data file. These extracted engineering units were saved as ASCII files.The ASCII files contained a header identifying each column and were labeled using thesame file-name conventions used for the raw data files (serial number and month of recovery), with the suffix changed to .DAT (e.g., 52019AP.DAT).

29

}'N i&t vt ':-; \,> 2:<2 \1. =I to j Data processing involved removing atmospheric effects from the recorded pressure measurements.

The instrument measured the total pressure resulting from both water elevation and the atmosphere.

Atmospheric pressure observations were obtained from outside sources (Attachment E-1) and subtracted from the total pressure readings.

Resulting water pressure values were then converted to water height values based on a water density of 62.96 lbsift (corresponding to a salinity of 6 ppt at 20'C). A constant value of water density was chosen for this conversion despite actual density variations with tides. An option for avoiding these density-induced conversionerrors was to measure density (via temperature and conductivity) at the pressure port. The important issue in this conversion was not that errors might be present but rather that the salinity was likely to vary in a similar manner from one gauge location to the next. For a sensor two meters below the surface, salinity changes of I ppt correspond to less than 0.2 cm error in absolute water elevation measurement.

These small errors were deemed acceptable.

Water heights were then adjusted to the NAVD88 datum based on survey data, resulting in the absolute water elevations.

Manufacturer-supplied calibrations performed accurate.temperature conversions, eliminating the need for manipulating those data.

III.A.3. Sample Plots Water elevation and temperature were displayed in time series plots as a function of Julian day (horizontal axis) with tide level (in feet) referenced to NAVD88 (vertical axis)in Figure 111-2. Temperature

(°C) is the vertical axis in Figure 111-3. The gap in data following Julian day 120 represents the instrument turnaround in early May.III.B. Current Measurements III. B. 1. System Description Estuarine currents result in part from differences in water elevation as the tide moves through the Estuary. Higher water on the southern boundary results in flows upstream;lower water at the same boundary induces an ebb, or downstream, current. Cross-channelelevation differences result in flows from one side of the Estuary to the other. Other factors such as Estuary geometry, Coriolis forces (effects of the earth's rotation), and wind can also affect circulation.

To gain an understanding of long-term current dynamics, four current meter moorings were deployed at the near-field region boundaries on each side of the navigation channel (Figure 111-4). Specifications and deployment dates are listed in Table 111-2.Each mooring consisted of a SeaPac SP2000 directional current meter (WHISL; Cataumet, MA). The instrument used the well-known Marsh-McBirney (Frederick, MD)4ýinch electromagnetic current sensor. The sensor records voltage induced across electrodes created by water passing through a delimited sphere surrounding the probe (typically a 14- to 16- inch radius). The electromotive force is directly proportional to current velocity.

Technical specifications for the current meters can be found in Postscript E.30 4 \ia~rTh The instrument is mounted vertically to a heavy, stable, tripod constructed of welded aluminum and weighing approximately 400 lbs (in air). The current probe was deployed 2 meters above the Estuary bottom.

The tripod configuration is shown in Figure 111-5.The moorings were installed at each location by lowering the package from a surface vessel to mid-water, after which each instrument was released to free-fall slowly to the Estuary bottom. Mooring positions were logged using GPS.Currents were measured using a burst average technique.

Every ten minutes, the instrument began a two-minute cycle of 1 k.Hz current sampling.

Each resulting group of 120 samples was averaged to obtain a single current velocity.

The resulting sampling yielded six records per hour, representing two-minute averages every ten minutes.The tripods were recovered using a remote mechanical release system fitted with a pre-set timer. A buoyant float with attached lightweight rope was held inside a mounted canister by a bumwire linked to the timer. At the preset time voltage sent to the burmwire chemically dissolved the constraint link. The float freely rose to the surface carrying with it the lightweight line that provided access to a heavier lifting line shackled to the top of the tripod. The lifting line was fed through the vessel winch and the tripod was hoisted aboard. Release timers were staggered over the day to facilitate recovery operations.

Upon recovery, data were uploaded to a shipboard PC. Data quality checks were performed, fresh batteries installed, and the instruments redeployed on the following day.The initial deployment was scheduled from 29 March to 2 May 1995. Two tripods, SDEL and NDEL, were recovered on 2 May. The NDEL tripod was recovered with a broken current sensor probe. Analysis of its data indicated that the instrument had failed approximately four days prior to recovery.

A backup SP2000 current meter, which had temporarily been installed in the vicinity of the Station (Section III.C.), was moved to the NDEL site to record data for the remaining deployment period. Technical problems with the two remaining tripod release systems delayed recovery of the NNJ and SNJ tripods until 18 May 1995, when they were recovered successfully by divers. These instruments were reinstalled the following day.Final recovery of all current meter moorings was performed on 26 June 1995.IIL.B.2. Data Processing Raw current data were stored on the PC hard disk in hexadecimal format. File-naming conventions paralleled those used for the tide gauges: (instrument serial number)(month of recovery).RAW.

For example, the raw data files from the NNJ sensor from May through June were labeled 50026JU.RAW.

Software was used to extract east velocity components, north velocity components,compass directions, temperature (1C), if a temperature sensor was used, followed by the time and date. Output files used the same file-naming convention, with the suffix 31 changed to .DAT. For example, the above raw file, after extraction, wýas labeled 50026JU.DAT.

\IATLABR-readv files, matrices stripped of identifying headers, were generated for data processing.

These files were named according to the following convention: (SN) (last three digits of instrument serial number).(month of recovery).DAT.

For example, the file SNO26JU.DAT represents data from the SN sensor number .026 recovered in June 1995.A coordinate transformation was performed on the data based on their location with respect to the navigation channel. The upstream direction was defined as the central axis of the Estuary navigation channel at the tripod location, based on NOAA navigation charts. For the north tripods, the transformation angle was defined as 26 degrees to the east of north. The upstream and cross-stream velocities (V) were then calculated as: Vupstream

= Vn.cos(26.0/180)

+ V,-sin(26.0/180)

Vcross-stream

= Ve.cos(26.0!180)

-V,.sin(26.e/180)

Where V, equals the uncorrected north velocity and Ve equals the uncorrected east velocity.The Estuary axis at the south tripod locations was oriented 318 degrees east of north.Transformations for south tripod data were calculated in a similar manner.III.B.3. Sample Plots Current data were displayed using a polar plot showing directions and magnitudes (Figures 111-6 and 111-7). This type of display shows current directions over a long period of time. The associated magnitudes are represented in polar form as radii emanating from the plot origin. The polar axes are oriented with north at the top of the page and east to the right. Figure 111-6 presents data from the first deployment period. Figure 111-7 presents data from the final deployment period.

Data were also displayed as a standard time series for each location showing upstream and cross-stream directions.

Upstream data are presented in Figure II1-8. Cross-stream data are presented in Figure 111-9.Data gaps at the NNJ site from Julian day 125 to 138 represent invalid data caused by the toppling of the tripod during an unsuccessful recovery attempt on 2 May 1995. Lost data at the SDEL site from day 148 through the end of the period resulted from tripod entanglement with commercial fishing gear. This tripod had also been toppled. The datagap for the NDEL site from day 120 to 125 resulted from the broken current probe described above. The gap in the SNJ site data resulted from instrument turnaround in mid-May 1995.8 32 II.C. Real-Time System A Real-Time System (RTS) was installed to collect long-term current and salinity data in the Salem intake basin. The RTS was installed approximately 250 feet rivetvard of the intake screens.A temporary, current monitoring system was installed in the vicinity of the Station on 29 March 1995. This was the same instrument which, upon recovery, was moved to the NDEL site to replace a broken tripod at that location (Section

[fI.B. 1.) The system consisted of a TABS (Texas Automated Buoy System) surface buoy. The system included a surface SeaPac SP2000 current meter (measuring currents approximately 2 meters below the surface), connected via chain to a second SP2000 current meter and abottom anchor.

The lower instrument was located approximately 30 feet below the surface. Data from the TABS surface buoy were lost during this period due to overcharging of the solar cell batteries used to supply power to the instrument.

Specifications for the SP2000 are shown in Postscript E. Data from the lower package were internally recorded at ten-minute intervals using the two-minute burst technique previously described. The lower gauge returned 100% of the desired data.The TABS system was replaced on 3 May 1995 by a long-term system which operated until spring 1996. This system consisted of meteorological sensors (wind speed and direction) mounted at the Station on a staff above the Northern Fish Count Building located near the intake structure and oceanogaphic sensors (currents, tide, temperature, and conductivity) mounted on a subsurface mooring centrally located in the vicinity of the Station. A shore station inside the Northern Fish Count Building controlled system communications and data logging.III. C 1.

1. eteorological Sensors Wind speed and direction were measured by a SensorMetrics Anometer [Model 05103](Metrics, Inc.; Lakeville, MA). Data were transferred from the sensor through a connecting cable to a SensorMetrics model ENV-50 shore station.

A RS-232 cable linked the shore station to the PC. Power was preconditioned and supplied at 110 VAC.The anemometer was mounted on a staff approximately 10 meters above the water surface to a security tower located outside the Fish Count Building.

III.C.2. Oceanographic Sensors Currents, tidal elevation, and salinity data were collected by two instrument packages in the RTS moored in the vicinity of the Station. The mooring consisted of a subsurface float with chain connecting the two instrument packages to an anchor. ae system is shown in Figure III-10.The top instrument package housed an SP2000 current meter, similar to the current meters deployed on the tripod moorings; and an FSI conductivity sensor, akin to the sensor included in the CTD instrument (Section 11), that provided conductivity data through an independent data port on the SP2200. The top instrument package was located approximately 16 feet below the surface on a mean tide.33 n.M a Lil -:IL The lower instrument package contained an SP2200 current meter with an internal Paros pressure transducer. Tide information was provided by the Paros gauge. The bottom package was located approximately six feet from the basin floor, or 33 feet below the mean tide elevation.

A multi-conductor power and communications cable linked the instruments to the shore-based PC. Power was supplied at the shore station through an uninterruptable power supply designed to prevent data loss in the event of power failures.III. C. 3. Shore Station The shore station provided system control and data management.

The PC used an IBM OS/2 operating system which allowed multiple applications to run concurrently.

Customized software controlled the oceanographic instruments and shore-based meteorological station. Four serial ports were connected to the two current instruments, the anemometer, and a telephone modem.

The computer monitored data detection as well as data type and validity (current, engineering, or noise). It also assigned the data to temporary storage buffers.

No data-sharing protocol was required, as each serial port functioned independently.

Data contained in the buffers were used to update the displays on the computer screen, and also were written to files on the hard disk. Data files stored on the hard disk contained both monitoring data and diagnostic information related to the instruments.

The screendisplayed Estuary currents, tidal elevation, salinity, and winds in near real time.Currents, conductivity, and pressures were measured continuously over ten-minute intervals.

At the end of each interval, the data were averaged to obtain a single value for each parameter.

A communications modem was installed to allow remote access to the data over a telephone line.The RTS logged data continuously until its retrieval in Spring 1996. Raw data files were downloaded from the on site PC hard disk for processing.

The file-naming convention was a modification of the conventions used for other SP2000 data sets. For example, data file RTJL9543.RAW refers to data from the RTS (RT), an abbreviated month of data recovery (JL for July), year of recovery (95), and instrument identifier (43 denotes serial number 2043). The .RAW suffix denotes a file in hexadecimal format. Several ASCII-formatted files resulted from processing the original raw data file (Table 111-3). Currents were output as east and north components of velocity.

Conductivity was used with temperature to calculate salinity using FSI software similar to that used to process the CTD psi data (See Chapter 2). Pressure was output directly as psi.The RTS data are displayed in a similar manner to data from the tripod-moored current meters. Polar plots representing the predominant direction and speed of the currents are shown in Figure III-1.1. Also included are time series plots for both gauges. The top gauge (east and north velocity with salinity) is presented in Figure 111-12. The bottomgauge (east and north velocity with pressure) is presented as Figure III-13.3 34

-\t~rill P I:'h h tI-i-i Figure 111- 12 shows a decreasing salinity as the spring turns to summer. This is contrary to independent CTD observations which show salinity levels rising through this period.This decrease in salinity as measured by the conductivity sensor was due to calibrationerrors resulting from increased biological growth on the outside ofthe inductive cell.Heavy growth within the sensing volume will reduce the measured conductivity and the resulting salinity calculations.

The contractor cleaned the cell in early September using divers to remove the growth, and maintenance dives were periodically carried out thereafter.

IV. METEOROLOGICAL DATAThree meteorological data files from the vicinity of Artificial Island, compiled by the National Climatic Data Center (NCDC) in Asheville, NC, were obtained and used to correct the pressure data recorded by the SP2200 tide gauges. These NCDC data were reformatted using MATLAB programs that converted the data into proper units and saved them as new data files. Wind speed and direction from Artificial Island from 29 March 1995 to the end of July 1995 are displayed in Figure i11-14. Figure 111-15 presents the atmospheric pressure with respect to wind speed.V. CONCLUSION This comprehensive field study amassed a library of hydrodynamic data on the portions of the Estuary immediately adjacent to the Station.The methods employed were tailored to the information being sought, and the resulting combination of ship-based operations, long-term moorings, and real-time data acquisition provided a suite of complementary measurements that elucidated the hydrodynamics of the Estuary.A five-mile stretch of the Estuary was examined in detail, with particular emphasis on thebasins near the intake and discharge structures of the Station. Measurements of surface and interior current velocity, tidal elevation, temperature, salinity, and meteorological components were recorded, stored, and catalogued for future reference.

These data were used at the time they were compiled to model physical processes in the vicinity of the Station. They are presented here for completeness.

[NTRODUCTiON The ADCP emrits an acoustic pulse called a ping. Scauerers that float ambiently with the water currents reflect some of the energy from the ping back to the ADCP. The ADCP uses the return signal to calculate a velocity. The energy in thts signal is the echo inten.st,.

Echo intensiry is sometimes used to determine information about the scatterers.

The velocity calculated from each ping has a statistical uncertainn.;

however, each ping is an independent sample. The ADCP reduces this statistical uncertainly by averaging a collection of pings. A collection of pines averaged together is an ensemble.

The ADCP's maximum ping rate limits the time required to reduce the statistical uncertainty to acceptable levels.The ADCP does not measure velocity at a single point, it measures velocities throughout the water column.

The ADCP measures velocities from its transducer head to a specified range and divides this range into uniform segments called depth cells (or bins). The collection of depth cells yields a profile. The ADCP produces two profiles, one for velocity and one for echo intensity.

The ADCP calculates velocity data relative to the ADCP. The velocity data have both speed and direction information.

If the ADCP is moving, and is within range of the bottom, it can obtain a velocity from retums off the bottom. This is called bottom-tracking.

The bottom-track information can be used to calculate theabsolute velocity of the water. The ADCP can get absolute direction information from a heading sensor.

,,u Table B-1 lists the specifications for all three models of ADCP's. About the specifications:

a. All these specifications assume minimal ADCP motion -pitch. roll, heave, rotation, and translation.

b. Except where noted, this specification table applies to typical setups and conditions.

Typical setups use the default input values for each parameter (exceptions include Pings Per Ensemble and Number of Depth Cells).

Typical conditions assume uniform seawater velocities at a given depth, moderate shear, moderate ADCP motion, and typical echo intensity levels.c. The total measurement error of the ADCP is the sum of: , Long-term instrument error (as limited by instrument accuracy).-The remaining statistical uncertainty after averaging.

-Errors introduced by measurement of ADCP heading and motion.d. Because individual pings are independent, the statistical uncertainty of the measurement can be reduced according to the equation: Statistical uncertainty for one ping = Square-root of number of pings 40

Acoustic signals are reflected from ambient sound scatterers in the water column; comparison of theemitted acoustic frequency with the backscattered frequency determines the doppler shift, proportional to thie relativespeed of the sound scatterers to the ADCP transducers.

The motion of the vessel is subtracted from the current ineasurements by acoustic "bottom-tracking".

The ADCPi measures current profiles (one current mcasurcinie per 50 cm depth bin) by "range-gating" the backscattered acoustic signal. Trigonometric reduction of the four inlependcnt heam measurements produces three (x-y-z) orthogonal current velocity components.

The Modified TMP was mandated by the unscheduled and extended outages experienced at SGS Units I and 2 since late spring of 1995. Unit No. 2 returned to steady state full power operation in mid-October 1997. Unit No. 1 returned to steady state full power operation in May 1998.PSE&G took advantage of the extended outage and conducted a survey of the spatial distribution of ambient river temperatures (Ambient Survey) in July, 1997. A thermal monitoring survey was conducted shortly after Salem Unit No. 2 returned to steady state full power operation (Single Unit Survey) in October, 1997. The Modified TMP makes reference to these two early surveys and their use in the new monitoring paradigm for thermal modeling presented in response to the SGS outages.The two monitoring components, the Ambient Survey and the Single Unit Survey, were conducted using the methods described below.The specific purposes of the Ambient Survey and/or the Single-Unit Survey were to:* Collect data on the spatial distribution of naturally occurring river water temperature in the Delaware Estuary in the vicinity of the Salem plant, 11-1

Collect additional data for the calibration and verification of the far-field hydrodynamic model,* Provide data for application of the models to characterize the thermal plume,.Collect data to improve our physical understanding of thermal inputs from shallow marshes surrounding the SGS, and 9 Support the biothermal assessment through improved understanding of thermal processes in the River, using both observational data and calibrated/verified model output 11.1 AMBIENT SURVEY 11.1.1 OBJECTIVES The Ambient Survey took place from 11 through 16 July 1997, when the SGS had not been discharging heated cooling water for nearly two years due to extended outages.The objective of the Ambient Survey was to obtain data on the spatial temporal variability of Delaware River water temperature in the absence of the SGS thermal discharge.

The field measurements represent data both from instruments at mooredstations, as well as mobile sampling by surface vessels equipped with oceanographic instruments.

Moored instruments were deployed concurrently for a five-day period from 11 through 15 July 1997. The mobile sampling was conducted on 14 and 15 July 1997, encompassing the full semidiurnal tidal cycles on each day. Meteorological data were collected at PSE&G's Artificial Island meteorological station prior to and during the Ambient Survey.Ancillary data collected by U.S. Government agencies during the Ambient Survey are presented in this report. These data include tidal water surface elevation measured by the National Oceanic and Atmospheric Administration (NOAA) and river flow gauged by the U.S. Geological Survey (USGS).8 11-2 The purpose of this portion of the report is to describe the methods and materials employed to collect the data (Section 11.1.2) and to present the data for the Ambient Survey (Section 11.1.3). Analysis and interpretation of these Ambient Survey data, conducted as part of the ongoing hydrothermal modeling, will be provided in the permitrenewal submittal (March 1999).11.1.2 METHODS AND MATERIALS 11.1.2.1 Overview of survey components The Delaware River Study Area covered by the Ambient Survey extends 12 nautical miles upstream and downstream of the SGS (Figure 11-1). The two major river-related elements of the Ambient Survey are: Mobile sampling -three survey boats occupied river transects on the Delaware River on 14 July 1997 and transects at the mouths of four tributary creeks on 15 July 1997.

Moored stations -oceanographic equipment was deployed at two river stations and at the mouths of three tributary creek stations from 11 through 15 July 1997.

The methods and measurement equipment used for the mobile sampling and at the moorings are described in the next two sections.

The manufacturers and model numbers of the equipment used and the manufacturer's specified accuracy are summarized in Table 11-1. The calibration of the equipment is summarized in Table 11-2.11.1.2.2 Mobile Sampling Three survey boats occupied five river transects positioned at the SGS, and at 6 and 12 nautical miles upstream (positive) and downstream (negative) of the SGS (Figure 11-2).In addition, transects at the mouths of four tributaries -

Salem River, Mad Horse Creek, Hope Creek and Alloway Creek -were completed during 15 July 1997.11-3 17 Each boat was equipped with a differential global positioning system receiver (DGPS), a conductivity/temperature/depth profiler (CTD), an Acoustic Doppler Current Profiler (ADCP), and a personal computer (PC) to record the data.

The configuration of the measurement and data recording equipment with the power supplies is shown schematically in Figure 11-3. An ADCP measures and records a profile of three-dimensional water currents at discrete vertical intervals between the sea surface and the bottom using acoustic sensing. A CTD measures and records the water conductivity, temperature, and depth of the instrument at programmable depth intervals.

Salinity is computed from the observed conductivity and temperature using internationally accepted formulae.

The DGPS makes use of radio positioning information transmitted by U.S. Department of' Defense satellites and by U.S. Coast Guard radio beacons to geographically position the receiver, typically to within 2 to 3 m.DGPS positions are calculated roughly every 2 sec.Three parameters were monitored in a two-step procedure at each transect.

First, temperature and conductivity ( for calculation of salinity) were measured near the water surface (at a depth of 1 to 2 ft), at multiple locations along each transect.

While the boat was underway along the transect, ADCP observations were made simultaneously at multiple depth levels throughout the water column. Second, vertical profiles of temperature and conductivity were measured at up to eight stations on each transect by lowering the CTD through the water. This monitoring sequence was repeated along each transect during four tidal phases on 14 July 1997: ebbing tide, slack water following ebb tide (end of ebb -EOE), flooding tide, and slack water following flood tide (end of flood -EOF).11.1.2.3 Moored Stations Oceanographic instruments were moored at five stations in the vicinity of the SGS (Figure 11-4):* Mooring E:* Mooring H;0 Mad Horse Creek mouth;a Hope Creek mouth; and e Alloway Creek mouth.S 11-4 All five stations were equipped with instruments measuring and recording water conductivity, temperature, and dissolved oxygen (DO) concentration.

Salinity was computed from the conductivity and temperature observations, as discussed above.Each station had a Conductivity/Temperature/Dissolved Oxygen (CT/DO) instrument and data logger located near the water surface, near mid-water, and near the bottom (Figure 11-5). The moorings also had redundant thermistors at each depth at all stations.

The moorings were deployed on 11 July 1997 and retrieved on 16 July 1997.A tide gauge was installed at the SGS barge slip. The vertical position of the gauge was surveyed to convert measured depth to water surface elevation relative to North American Vertical Datum (NAVD). Local surveyors (Taylor Wiseman and Taylor) used differential leveling to transfer an elevation from PSE&G Control Network Monument Artis 2 to the SGS barge slip and then checked the level using the Artis 3 monument to within 0.01 ft.The CT/DO instrument was a YSI Model 600XLM, the thermistors were Onset Optic Stowaways, and the tide gauge was a Coastal Leasing MicroTide.

All values of manufacturer's specified accuracy are listed in Table 11-1.11.1.2.4 Ancillary Data Collected by NOAA, USGS and PSE&G The contractor collated the following ancillary data collected by the USGS, NOAA and PSE&G as part of their respective routine environmental monitoring programs.* Water surface elevation as gauged continuously by NOAA at four locations within the Delaware River Estuary: NOAA STATION RIVER MILE Lewes, Breakwater Harbor 0.0 Cape May 1.2 Reedy Point 58.2 Philadelphia 98.3* Freshwater flow of the Delaware River at Trenton, New Jersey, as gauged by the USGS (Gauge No. 01463500).

Mobile survey measurements

2. Moored station measurements

3. Tide data 4. Tributary creek flow and heat fluxes 5. Ancillary meteorological and hydrological data 11.1.3.2 Mobile Survey Measurements 11.1.3.2.1 Vertical profiles of salinity and temperature.

Vertical profiles of conductivity and temperature of the Delaware River were measured at four phases of the semidiurnal tide on 14 July 1997. Salinity was calculated from these data. Results are presented by showing location where vertical profiles were taken, temperature profiles corresponding to those locations, and salinity profiles.

Data plots are arranged in rows corresponding to the five transects from north to south (i.e., +12 nautical miles,+6 NM, 0 NM, -6 NM, and -12 NM). Each column corresponds to a profile along the transect, either to the west, center, or east of the navigation channel. Each phase describes a two-hour interval relative to the NOAA predicted tidal elevation phase at Artificial Island. Transect stations not sampled, because of field logistical problems, are indicated by a missing plot.811-6 The 12 figures selected as representative of the mobile survey vertical are: TIDAL STATION TEMPERATURE SALINITY PHASE LOCATIONS EOF Fig. 11-6 Fig. 11-7 Fig. 11-8 Ebb Fig. 11-9 Fig. 11-10 Fig. 11-11 EOE Fig. 11-12 Fig. 11-13 Fig. 11-14 Flood Fig. 11-15 Fig. 11-16 Fig. 11-17 11.1.3.2.2 Temperature of water surface.

River current velocities measured using ADCPs are presented as cross-sectional plots for the five transects, arranged from the most upstream transect at the top of the page to the most downstream transect at the bottom of the page. The four figures showing the river cross-sectional velocity are: 11-7ý%q 0 TIDAL PHASE FIGURE NO.EOF 11-22 Ebb 11-23 EOE 11-24 Flood 11-25 The transects were not measured simultaneously, since the vessels had to proceed from one transect to another. Therefore, the data from different transects were not collected synoptically during any single phase of the tide.Color represents the magnitude and direction of velocity perpendicular to the river transect (that is, along-channel speed). The color-coded scale on each figure differs to accentuate the lateral and longitudinal variability in velocity for each transect sample.The river discharge along each transect was computed using the velocity and associated cross-sectional.

The estimated discharge is presented on each figure.11.1.3.3 Moored Station Measurements 11.1.3.3.1 Vertical profiles of temperature, salinity, and dissolved oxygen. The data recorded at surface, mid-water, and bottom levels at the five moored stations during the 2-hr tidal phase intervals defined for the 14 July 1997 survey are presented as a series of vertical profiles.

The minimum, maximum, and mean at the three depths are shown as end bars and a solid circle, respectively, in each plot. Each temperature bar is computed using both the CT/DO and the thermistor measurements at each depth level. Similar presentations of salinity and dissolved oxygen data are also made. The 12 figures showing the data for the two river and three marsh creek mouth moored stations are: Tidal Temperature Sahlny DO EOF Fig. 11-26 Fig. 11- Fig. 11-34 Ebb Fig. 11-27 Fig. 11- Fig. 11-35 EOE Fig. 11-28 Fig. 11- Fig. 11-36 S Flood Fig. 11-29 Fig. 11- Fig. 11-37 11-8 DO data failing QAJQC, included the mid-water measurements at Hope Creek and the surface observations at Mad Horse Creek. The symptoms suggest a meter malfunction.

The DO meter at the surface of Mad Horse Creek apparently malfunctioned on 12 July 1997 (see Section 11.1.3.3.2).

All other DO measurements in the Delaware River and Alloway and Hope creeks were consistently close to saturation.

11.1.3.3.2 Time series in temperature, salinity, and dissolved oxygen The time series of temperature, salinity and DO data recorded at individual CT/DO instruments are presented in the following figures: Station Temperature Salinity DO Delaware E Fig. 11-38 Fig. 11-43 Fig. 11-48 Delaware H Fig. 11-39 Fig. 11-44 Fig. 11-49 Alloway Creek Fig. 11-40 Fig. 11-45 Fig. 11-50 Hope Creek Fig. 11-41 Fig. 11-46 Fig. 11-51 Mad Horse Fig. 11-42 Fig. 11-47 Fig. 11-52 Creek The DO data also passed QNQC, except at Mad Horse Creek following 12 July 1997, and the mid-water DO data at Hope Creek (see previous section).

11.1.3.4 Tide Data The water surface elevation measurements recorded by NOAA at Lewes, Cape May, Reedy Point, and Philadelphia and by PSE&G at the SGS are shown as Figure 11-53.The lower plot in this figure shows the tides on 14 July 1997. The average tidal range for the six days of measurement and 14 July 1997 shows a general increase from themouth of the river to Philadelphia (Figure 11-54). The lag in the time of high and low water relative to the mouth of the River is shown in the lower plot of this figure. For 11-9 comparison, NOAA tidal forecasts, based on long-term tidal records for the five river stations (referred to previously), are presented in Figures 11-55 and 11-56. The tidal range and times of low and high water predicted by NOAA generally match the observed data.11.1.3.5 Hydrological and Meteorological Data The time series flow in the Delaware River observed at the USGS Trenton gauging station and the meteorological data observed at the Artificial Island station for the period just prior to and during the Ambient Survey are shown in Figure 11-57. The two weeks prior to and including the 14 and 15 July 1997 mobile survey were periods of generally fair weather.Daily maximum air temperatures ranged from the mid-70s to the low-90s, and the overnight low temperatures ranged from the mid-60s to the mid-70s. The barometric pressure record suggests that a relatively stable air mass occupied the region during the entire period, with no storms or frontal movements, and the wind speeds and directions were correspondingly moderate and steady. The Artificial Island rain gauge recorded no rainfall during the two-week period prior to and including the mobile survey.Delaware River flows for the two weeks prior to the mobile survey ranged between 3000 and 4000 cfs, typical of a period of little regional rainfall.

According to the USGS Water Resources Data, New Jersey 1996, the long-term mean river flow at the Trenton gauge during July is 7104 cfs.11.1.3.6 Summary of Survey Results The data collected during the Ambient Survey provide a characterization of ambient river conditions in the vicinity of SGS. In general, the data passed QAJQC procedures (with few exceptions as noted in the text), and are therefore usable in defining background summer, low river flow conditions.

011-10 I 11.2 SINGLE-UNIT SURVEY 11.2.1 OBJECTIVES The second thermal survey took place between 21 and 30 October 1997, a period when only one (Salem Unit No. 2) of the two power generating units was operating.

This thermal survey had as its objective the collection of data to support the far-field hydrodynamic modeling.As with the Ambient Survey, moored stations and mobile surveys were included as the means of data collection.

However, the scopeof this survey surpassed that of the Ambient Survey in several aspects. It included: " A greater number of moored stations were installed* Initial conditions were sampled at the beginning of survey* Additional tide gauges were installed* A bottom-mounted ADCP was deployed" Additional boats participated in the mobile survey The primary components of the Single-Unit Survey included: " Initial conditions survey" Tidal boundary survey* Tide gauges" Moored stations" Fixed-station ADCP" Mobile survey of river* Mobile survey of marsh mouths" Ancillary data Section 11.2.2 describes the methods and materials employed to collect the data. The data for the Single-Unit Survey are presented in Section 11.2.3.

Analysis and interpretation of the Single-Unit Survey data will be conducted as part of the ongoing hydrothermal modeling and will be described in the March 1999 permit renewal submittal.

11.2.2 METHODS AND MATERIALS 11.2.2.1 Overview of Survey Components The Single-Unit Survey covered the Delaware River from Trenton, New Jersey, to the mouth of Delaware Bay at Cape May, New Jersey. However, measurements were concentrated on the reach that extends 12 NM upstream and downstream of SGS. The overall sampling scheme consisted of moored oceanographic meters deployed at selected locations to record data during, before and after a period when mobile surveys took place. A timeiine of the survey components is shown in Figure 11-58. The major components of the Single-Unit Survey included: Initial Conditions Survey -Vertical profiles of conductivity (salinity) and 'temperature were measured at 16 stations spaced at 5- to 10-nmile increments between river miles 0 and 120 using two boats on 21 October 1997., Tidal Boundary Survey -Vertical profiles of conductivity and temperature were measured at three locations spaced along the Delaware River mouth during flood using one boat on 27 October 1997.Tide Gauges -Water surface elevations were measured at six locations between 14 and 28 October 1997.Moored stations -Meters were deployed at three depth levels at moorings -set at 24 locations to measure temperature at all locations and conductivity (salinity) and DO at selected locations between 21 and 31 October 1997.Bottom Mounted ADCP -Current velocity was measured at one location near the discharge between 16 and 18 October 1997.Mobile surveys -Five survey boats occupied river transects on 28 October 1997.Mobile surveys of marsh mouth -The four tributaries of the Delaware River covered by the Ambient Survey were also monitored during the Single-Unit Survey and were conducted at the mouths of four tributaries on 29 October 1997 11-12 Ancillary data -Various ancillary oceanographic and meteorological data from available sources were compiled to support the data collection effort.The methods and measurement equipment used for these survey components are described in the following sections.

The manufacturer and model number of the equipment used and the manufacturer's specified accuracy are summarized in Table 11-3. The calibration of the equipment used in the Single-Unit Survey is summarized in Table 11-4.11.2.2.2 Initial Conditions Survey Calculation of river temperatures and hydrodynamics using the hydrothermal model of the Delaware River requires initial conditions as input to the model. The initial conditions for the one-week survey period were measured on 21 October 1997.Conductivity (salinity) and temperature were measured throughout the water column using Falmouth Scientific Inc. CTDs at 16 locations along the navigation channel from the Delaware River mouth to Trenton, at river mile (RM) locations:

0, 10, 20, 30, 40, 45, 50, 55, 60, 65, 70, 80, 90, 100, 110, and 120 (Figure 11-59). One vessel covered from the Delaware River mouth to RM40 and the second vessel covered from RM45 to RM120.11.2.2.3 Tidal Boundary Survey Vertical profiles of conductivity and temperature were measured at three locations spaced along the Delaware River mouth during flood using one boat on 27 October 1997.Three tide-gauges were occupied as part of the tidal boundary survey component; locations of the gauges are shown on Figure 11-60.11.2.2.4 Tides Gauges Tide gauges were installed by LMS at six stations along the Delaware River: " Cape May* Woodland Beach (near Ship John Shoal)11-13 e Salem Barge Slip e Western C&D Canal e Eastern C&D Canal (Reedy Point)e Marcus Hook In addition, NOAA maintains continuously-recording tide gauges at four locations (see Section 11.1.2.4). The locations of the 10 tide gauging stations are shown in Figure 11-61.11.2.2.5 Moored Stations Moorings equipped to measure certain parameters were installed at twenty-four stations in the river and at the mouths of three tributaries (see Figures 11-5 and 11-62).The oceanographic parameters measured at these stations varied as follows: Temperature, conductivity, and DO -five stations (same locations as Ambient Survey stations)Temperature and conductivity

-nine stations Temperature ten stations The sensors for temperature and/or CT/DO deployed at surface, mid-water, and bottom positions for each moored station are listed in Table 11-5.All moorings were deployed between 15 and 16 October 1997. Two of the 24 moorings, were lost during the deployment; the remaining 22 moorings were retrieved between 31 October and 4 November 1997.11.2.2.6 Fixed Station ADCP An ADCP was deployed by divers in the vicinity of SGS's discharge on 16 October.1997. The location of the ADCP is shown on Figure 11-66 After deployment an electrical cable on the unit frayed, presumably by its motion and contact with mooring hardware.

This the frayed cable resulted in termination of data logging on 18 October 1997. The ADCP was retrieved on 30 October 1997.11-14 11.2.2.7 Mobile Surveys Five survey boats occupied the transects shown in Figures 11-63, 11-64 and 11-65.Two boats occupied the same transects during each of four tidal phases sampled on 28 October 1997: Boat Number 4 -Transects

+6 and + 12 NM Boat Number 5 -Transects

-6 and -12 NM The transects covered by the remaining three boats depended on the tide. Boats 2 and 3 covered the river east of the navigation channel and were generally upstream and downstream, respectively, of SGS during ebb and flood tide. The transects these two boats occupied shifted upstream for the EOF phase and downstream for the EOE phase to track the higher temperatures that were likely within the thermal plume. Boat1 occupied the 0 NM transect (full width of the river) during all four tidal phases and was used as a "rover" to delineate the thermal plume in the vicinity of the discharge (Figure 11-65). 0 All boats were equipped with DGPS receivers, a CTD, and a PC, as described previously (Section 11.1.2.2 and Figure 11-3). Sampling for temperature and conductivity was performed two ways: (1) temperature and conductivity (salinity) measurements were obtained from a depth of I to 2 ft (near water surface) as the boat traveled along the transects, and (2) vertical profiles of temperature and salinity at a number of stations when the boat was stopped. For sampling method 1, the three boats closest to the SGS thermal discharge (Boats 1, 2, and 3) were equipped with Ocean Temperature Modules (OTM). The three boats measured temperature as they were underway along the transects, whereas Boats 4 and 5 were -required to stop periodically to take near-surface temperature measurements.

The OTM equipment allowed more frequent measurements in the vicinity of the discharge, where larger horizontal temperature gradients occur.

For sampling method 2, the CTD was lowered at vertical profiling stations from each of the five vessels, and recorded data from the water surface to the bottom at closely spaced, but discrete, depth intervals.

Boats 1, 4, and 5 were also equipped with ADCPs to measure current velocity at various depth strata.11-15 all 0 Due to high winds and accompanying rough water, some transects were not occupied.11.2.2.8 Mobile Surveys of Marsh Mouths The four tributaries of the Delaware River covered by the Ambient Survey (Salem River, Mad Horse Creek, Hope Creek, and Alloway Creek) were also monitored during the Single-Unit Survey. The CT/DO meters on Boats 1 and 4 (see Table 11-3) were used to measure temperature, conductivity (salinity), DO, and current velocity during four tidal phases on 29 October 1997.11.2.2.9 Ancillary Data The Delaware River data routinely collected by NOAA, USGS, and PSE&G, which were described in Section 11.1.2.4, were also collected during the Single-Unit Survey.11.2.3 RESULTS 11.2.3.1 Overview of Data The data recorded during the Single-Unit Survey were downloaded and compiled.

All data were subjected to QA/QC procedures.

Data missing from the two lost moorings and abbreviated measurements by the bottom ADCP represent a approximately 1% of the data collected, thus providing sufficient data to support thermal modeling.The results of the field measurements are presented graphically in the following subsections.

11.2.3.2 Initial Conditions Survey The vertical profiles of temperature at the 16 stations along the River are presented in Figures 11-66 and 11-67. The vertical profiles of salinity are shown in Figures 11-68 and 11-69.0 0 11-16 11.2.3.3 Tidal Boundary Survey Vertical profiles of temperature and salinity are presented for three stations at the mouth of the River along the model boundary transect.

The plots of temperature and salinity data taken at five time intervals during flood tide are shown in Figures 11-70 and 11-71, respectively.

11.2.3.4 Tide Gauges The water surface elevations measured at six tide gauge stations installed for the Single-Unit Survey were converted to the common datum (NAVD) by surveying from avertical control benchmark.

In addition, data recorded by NOAA at their four tidal gauging stations were also converted to NAVD. The tidal variations in water surface elevation between 21 October and 1 November 1997 at these 10 stations are shown in Figures 11-72 and 11-73 The time series during the mobile survey of 28 October 1997 are shown in Figures 11-74 and 11-75.The average and minimum/maximum ranges in tide between high and low water are shown for the 11-day period and the single day in Figure 11-76. The tidal elevation time delay, or phase lag from the mouth upstream to Philadelphia, is shown similarly in Figure 76.11.2.3.5 Moored Stations22 of the 24 moorings set in the River and at the mouths of tributaries were retrieved; moorings 8 and 21 were lost. Three of the 66 retrieved meters had data losses due to instrument malfunction:

Mooring 3 surface Mooring 3 bottom Mooring 10 surface Two instruments sampled at the wrong sampling rate (12 hrs. instead of 10 minutes): Mooring 3 mid-water Mooring 4 mid-water 11-17

@3I The temperature, salinity and dissolved oxygen data are presented graphically in two ways: vertical profiles and time series.The vertical profiles of temperature, salinity, and DO are presented as sets of five figures for each tidal phase. Each tidal phase presents data from different locations, and includes temperature, salinity, and dissolved oxygen monitoring results: Tidal Phase Location Temperature Salinity DO Flood Fig. 11-77 Fig. 11-78 Fig. 11-79 Fig. 11-80 Fig. 11-81 EOF Fig. 11-77 Fig. 11-82 Fig. 11-83 Fig. 11-84 Fig. 11-85 Ebb Fig. 11-77 Fig. 11-86 Fig. 11-87 Fig. 11-88 Fig. 11-89 EOE Fig. 11-77 Fig. 11-90 Fig. 11-91 Fig. 11-92 Fig. 11-93 The mean value of each 2-hr interval is shown as a dot and the minimum and maximum values are shown as the ends of horizontal bars. Data availability is tabulated in Table 11-5.11-18 0 0 The time series of temperature, salinity, and DO are shown for all 22 moored stations: Station 1 2 3 4 5 6 7 9 10 Alloway Creek Hope Creek Mad Horse Creek E H I K V L N 22 23 24 Temperature Fig, 11-94 Fig. 11-97 Fig. 11-99 Fig.11-101 Fig.11-103 Fig.11-105 Fig.11-107 Fig. 11-109Fig.11-111 Fig.11-113 Fig.11-116 Fig.11-119 Fig.11-121 Fig.11-124 Fig.11-127 Fig.11-128 Fig.11-129 Fig.11-130 Fig.11-131 Fig.11-132 Fig.11-133 Fig.11-134 Salinity Fig. 11-95 Fig. 11-98 Fig.11-100 Fig.11-102 Fig.11-104 Fig.11-106 Fig.11-108 Fig.11-110 Fig.11-112 Fig.11-114 Fig.11-117 Fig.11-120 Fig.11-122 Fig.11-125 DO Fig. 11-96 Fig.11-115 Fig.11-118 Fig.11-123 Fig.11-126 The DO data at the bottom of Alloway Creek and the surface of Hope Creek are suspect. Similarly, the bottom DO at Station E appears questionable.

All other data passed QA/OC checks.11.2.3.6 Fixed Station ADCP The current speed and direction measured by the bottom-mounted ADCP at 5-ft depth intervals are shown in Figure 11-135. This gauge was deployed near the discharge location.11-19 11.2.3.7 Mobile Survey of River The measurements taken during the mobile survey of the Delaware River on 28 October 1997 are presented as plots of surface isotherms and as vertical profiles.

The surface temperature plots for each of the four tidal phases cover the full 24-mile extent of the river,. as well as a close-up of the vicinity of the SGS discharge.

The eight figures showing surface temperatures are: Tidal Phase Full Extent Close-up Flood Fig.11-136 Fig.11-137 EOF Fig.11-138 Fig.11-139 Ebb Fig.11-140 Fig.11-141 EOE Fig.11-142 Fig.11-143 Sb The vertical profiles of temperature and salinity are shown as sets of five figures for each tidal phase: location of vertical profile stations, and two figures each of temperature profiles and salinity profiles at representative stations:

Barometric pressure* Solar radiation* Dew point temperature

Cloud cover 11-21 These data are shown graphically in Figure 11-176. Hourly precipitation data also collected at PSE&G's monitoring station show rainfall on five days during the survey period: Day in October 1997 19 24 25 26 27 Rainfall (in.)0.12 0.10 0.77 0.56 0.06 Sb These meteorological data show a storm preceding the mobile survey. The flow in the Delaware River at Trenton increased on 25 October 1997 and then decreased on 28 October 1997 according to USGS river-gauging data (Figure 11-177).11.2.3.10 Summary of Survey Results The data collected during the Single-Unit Survey met the survey objective and contributes data and information useful for the nearfield and farfield models. Small data gaps identified in this report pose no significant risk to the modeling success.11.3 LITERATURE CITED U.S. Environmental Protection Agency (EPA). 1985.

Objectives As part of the renewal-of the New Jersey Pollutant Discharge Elimination System (NJPDES) permit, thermal surveys were conducted by Lawler, Matusky & Skelly Engineers LLP (LMS) for Public Service Electric & Gas Company (PSE&G) to obtain data for the renewal of the New Jersey Department of Environmental Protection (NJPDES) Permit for the Salem Generating Station (the Station).

The work plan for thissurvey was described in the Technical Basis Document for the Modified Thermal Monitoring Program (Modified TMP) that was submitted by PSE&G to NJDEP (PSE&G 1998a). The survey primarily consisted of intensive sampling of the river during May and early June 1998, when both power-generating units were operating. The intensive survey was supplemented by mooring station monitoring that extended the temperature data collection through early November. The May through early June period is referred to as the intensive survey, whereas the May through November period is referred to as the six-month moorings for thermal monitoring. The objective of the 2-Unit survey was to obtain data on the Delaware River at a time when the plant was operating at full capacity.This intensive survey utilized moored instruments and mobile boats to cover the study area.The components of the 2-Unit intensive survey are:* Longitudinal survey* Tidal boundary survey* Tide gauges* Dye dilution* Mooring stations* Fixed-station Acoustic Doppler Current Profilers (ADCPs)° Mobile survey of river* Mobile survey of marsh mouths* Infrared aerial photographs In addition, data on meteorology and hydrology collected by other organizations are also included in this chapter. This first section (2-Unit Intensive Survey) of the chapter has two remaining subsections.

The first subsection (Section I.A.2) describes the methods and materials employed to collect the data for the 2-Unit intensive survey, and the second section (Section I.A.3) presents the data. The second section (Six-month Moorings for 20 PSE&G Permit Appiication 4 March I191)Exhibit E-1 -3 Thermal Monitoring) also includes two sections that describe the methods and materials and the results.LA.2. Methods and Materials This section begins with a brief description of the survey components to. provide an overview of the types of sampling and measurements performed.

The quality control and quality assurance steps taken to validate the accuracy of the scientific equipment used then summarized.

A description of each survey component in terms of the measurement techniques, sampling locations, and duration and frequency of measurements comprises the remaining subsections of Section I.A.2.[A.2.a. Overview of Survey Components The 2-Unit survey covered the Delaware River from Trenton, New Jersey, to the mouth of Delaware Bay at Cape May, New Jersey. Measurements were concentrated on the reach that extends six miles upstream and downstream of the Station (Figure 10-1). The overall sampling scheme consisted of monitoring instruments deployed at selected locations to record data during, as well as before and after, a period when other measurements were taken by crews using boats. A timeline of the survey components is shown in Figure 10-2. The major elements of the 2-Unit survey are: Longitudinal Survey -Vertical profiles of conductivity (salinity) and temperature were measured at17 river stations spaced at 5- to 10-mile intervals along the navigational channel between River Miles (RM) 0 and 130 using two boats. [River miles are based on referencing by the Delaware River Basin Commission (DRBC).] Six of the 17 stations also had lateral sampling points on the left and right side of the shipping channel. The three longitudinal surveys were performed on 21 and 27 May and 2 June 1998.Tidal Boundary Survey -Vertical profiles of conductivity and temperature were measured using one boat at three locations spaced along the mouth of the bay during a flood tidal phase on 22 May 1998.Tide Gauges -Water surface elevations were measured at four locations between 19 May and 4 June 1998 to supplement tidal data collected by others.Mooring Stations -Meters were deployed at three depths each for 31 mooring locations to measure temperature at all locations, and conductivity (salinity) and dissolved oxygen (DO) at selected locations, between 19 May and 4 June 1998.Fixed-Station ADCP -Current velocities throughout the total water depth'were continuously measured at one location near the discharge between 19 May and 3 June 1998.Dye Injection

-A fluorescent dye was injected into the Station discharge from 27 to 29 May 1998 to track its mixing and transport in the Delaware River.21 PSE&G Permit Apphcation 4 March 19'4)Exhibit E-1 -3 Mobile -Five survey boats occupying river transects concurrently measured temperature, salinity, and dye concentration on 29 May 1998; transects at the mouths of two tributarieswere sampled on 30 May and 29 June 1998.Infrared Aerial Photographs -Thermal images of surface water temperature in the vicinity of the Station discharge'pipe were taken on 29 May 1998.Collectively, these survey components provide synoptic data of distribution of temperature at the water surface and over the depth of the river. In total, the survey data provide the basis for calibrating nearfield and farfield models of the Delaware River near the Station.l.A.2.b. Quality Assurance/Quality Control (QAIQC)The accuracy and precision of the data collected during the 2-Unit survey were ensured through the development and implementation of a QA/QC Plan. The plan described the procedures to be followed during several stages of the survey: equipment calibration/validation, field application (measurements), documentation, and data handling.

All scientific instrumentation for measuring temperature, conductivity/salinity,DO, depth/pressure, velocity, dye concentration, and boat position had a certain manufacturer-specified accuracy.

'The survey equipment (by manufacturer and model)used during the 2-Unit survey is summarized in Table 10-1. In addition, the equipment was tested independently as part of the survey to confirm that the accuracy of the equipment to be used on this survey was within a margin of error that could be tolerated without compromising the intended use of the data. The accuracy tolerance level set for the pre-survey testing of the equipment will be referred to hereafter as the calibration/validation accuracy.Temperature.

The equipment used to measure water temperature in the river along with the manufacturer's specified accuracy and calibration/validation accuracy was:

2 CT is an instrument that measures and records conductivity (salinity) and temperature.

3CT/DO is an instrument that measures and records conductivity (salinity), temperature, and DO.The equipment used in the mobile and longitudinal survey components responds faster to changes in temperature and therefore has greater accuracy than equipment used on the moorings.

These technologically advanced instruments provide refined measurements on board boats passing through regions of varying temperature.

The fast-response Thermistor Temperature Modules (TTM) have the highest accuracy of all the survey equipment. Temperature measurements taken by the five boats during a two hour 22 PSE&G Permit Application 4 March 1999 Exhibit E-I-3 duration were compiled and plotted to provide a "snapshot" of the Station's thermal plume. Water baths with accuracies of +/-0.2'C and +/-0.05°C were used to test the moored equipment and more +/-0.2 0 C and +/-0.05'C accurate mobile equipment, respectively.

The protocol for calibration/validation of the temperature equipment is described in Appendix A. Briefly, the moored thermistors and CT and CT/DO meters were tested prior to the survey and then re-tested after the survey. The temperatures measured by the meter/thermistor and a National Institute of Standards and Testing (NIST)-certified thermometer in four different temperature baths (0.0, 25.0, 30.0, and 37.0°C) were recorded.

Thermistors/meters that did not read within 0.2*C of the certified thermometer during the pre-survey test were used only if the reading could be appropriately corrected.

For example, a known difference between the meter and the certified thermometer can be used to adjust or correct the temperature readings.

The procedure used for correcting temperature readings is described in Section I.A.3.b.All CTD instruments used in the mobile survey were tested prior to and after the survey at Falmouth Scientific Inc. (FSI) laboratory in Cataumet, Massachusetts.

The test of all shipboard temperature instruments at a single laboratory assured interequipment comparability and consistency of the compiled mobile survey data (see Appendix A for further details).Conductivity/Salinity.

Conductivity, which is a surrogate measure of salinity, was measured using CT, CTD, and CT/DO meters. Five standard solutions, having prescribed conductivities that cover the expected range of salinity in the study area, were used to test the meters used during the 2-Unit survey. The protocol for calibration/validation of the conductivity/salinity meters is described in Appendix B along with the equations for converting conductivity to salinity.

The manufacturer's specified accuracy and calibration/validation tolerances for salinity are summarized below for the three types of meters used.SURVEY MANUFACTURER=S SPECIFIED CALIBRATIONNALIDATION COMPONENT EQUIPMENT ACCURACY (salinity, ppt) ACCURACY (salinity, ppt)Mobile CTD +/-0.01 1.0 Moorings CT +/-0.1 1.0 Moorings CT/DO +/-0.1 1.0 NOTE: Manufacturers are listed in Table 10-1.Dissolved Oxygen. The CT/DO equipment used on the moorings was initially calibrated by the manufacturer.

These meters were also calibrated at LMS' laboratory prior to and after the 2-Unit survey using the saturated air chamber calibration procedure (see Appendix C). A second calibration procedure, which uses oxygen-saturated water, was performed prior to the survey. The pre-survey calibration entailed adjusting the instrument to attain the saturation concentration before reading, if necessary.

The instrument reading during the post-survey calibration was recorded and compared to the saturation concentration before readjusting the instrument, if necessary.

The following table presents both the manufacturer's specified accuracy and the calibration/

validation accuracy for all DO equipment used.23 PSE&G Permit Application 4 March 1999 Exhibit E.I-3 SURVEY MANUFACTURERES CAUBRATIONNAUDATtON COMPONENT EQUIPMENT SPECIFIED ACCURACY (mg/1) ACCURACY (mg/I)Moorings CT/DO. +/-0.2 +/-0.4 NOTE: Manufacturer is listed in Table 10-1.Depth/Pressure.

All depth/pressure instrumentation was initially calibrated by the manufacturer.

Each tide gauge was further tested in the field by placing it at a water depth (at the tide gauge station) that was measured using a rigid steel tape measure. The density of the overlying water was estimated and the unit weight was calculated as density times unit weight of fresh water (62.4 lb/ft 3). The pressure reading of the meter was converted to excess pressure (i.e., above atmospheric pressure) by subtracting an assumed constant atmospheric pressure of 14.7 psi.D = PK UW where: D = depth (ft)Pe = excess pressure (lb/in.2)UW = unit weight of water (lb/ft 3)K = conversion factor (144 in.2/ft 2)The depth (based on the meter pressure reading) was compared to the distance measurement.

All comparisons were checked in relation to the calibration/validation tolerance stated below.SURVEY EQUIPMENT MANUFACTUREIRDS CALIBRATIONNALIDATION COMPONENT SPECIFIED ACCURACY (im) ACCURACY (m)Tide gauges Tide gauges +/-0.05 +/-0.2 NOTE' Manufacturer is listed in Table 10-1.Velocity.

Velocity instrumentation consisted of Acoustic Doppler Current Profilers (ADCPs), a technology for measuring the current velocity at various depth intervals within the water column (see Appendix E for more information). All velocity instrumentation was initially calibrated by the manufacturer, which was assumed sufficient because ADCPs do not typically drift more than the specified accuracy.The bottom-mounted ADCP compass was calibrated according to the manufacturer's recommended procedure, thereby ensuring accurate direction readings.

This calibration was performed at the Delaware City Marina on 11 May 1998 prior to deployment.

Under normal operation, the manufacturer's specified accuracy is assumed to be attained.If the instrument is not operating normally, erratic readings are displayed or recorded.The following table presents the velocity equipment manufacturer's specified accuracy.24 PSE&G Permit Apphcation-t March 199 Exhibit E-l-3 SURVEY MANUFACTURERDS SPECIFIED COMPONENT EQUIPMENT ACCURACY (FPS)Mobile ADCP +/- 0.04 to 0.07 Moo rings ADCP +/- 0.04 to 0.07 NOTE: The accuracies of +/-0.04 and 0.07 fps were calculated according to the manufacturer's (RD Instruments) formula at velocities of 0 and 12.3 fps, respectively.

Mobile velocity instrumentation was tested with real-time display prior to the survey.The protocol for monitoring the equipment's performance is described in Appendix E.Dye Injection and Sampling.

The rate of dye injection was measured based on electronic scales and fluorometers (as described in Section I.A.2.c).

The scales were calibrated by the manufacturer and then calibrated at Salem on 18 May 1998 to assure interequipment calibration/validation.

The calibration protocol for the electronic scales is presented in Attachment F. The fluorometers were calibrated on site using the protocol described in Appendix G.Prior to the discharge of the fluorescent dye (Rhodamine WT) through the Station's discharge pipe, the background fluorescence of the Delaware River, attributable primarily to algae, was measured. The mean background fluorescence was used to adjust measurements of dye taken after the injection of dye into the Station discharge as described in Appendix G.The following table presents the dye sampling equipment manufacturer's specified accuracy for both the electronic scales and fluorometers.

SURVEY MANUFACTURERWS COMPONENT EQUIPMENT SPECIFIED ACCURACY Dye Study Scale 50 g Dye Study Fluorometers 2%NOTE: Manufacturers are listed in Table 10-1.The accuracy of the electronic scales can be expressed in terms of their function in measuring the mass rate of dye injection. The rate at which dye was pumped from thedrum on each electronic scale was approximately 8.75 kg/hr. If an hourly scale reading deviates by the manufacturer's accuracy, the accuracy of the hourly mass rate is approximately 0.5% (or 100 x 50/8,750).The accuracy of the fluorometer measurements of dye concentration was assured throughon-site calibration of the fluorometers used at the plant and on the boats. The accuracy of the dye concentration measurement is dependent on: (1) the accuracy of measuring volumes of dye solution and dilution water used to produce the "known" dye concentrations; (2) variability in the fluorometers' reading of a single sample (interfluorometer variability);

and (3) method precision or "instrument drift"; and (4)background fluorescence variability.

25 PSE&G Permit Appiicanion 4 March 1999 Exhibit E-I1-3 Position and Time. Position and time data associated with deployment of fixedinstruments (moorings, bottom-mounted ADCP) and shipboard measurements (mobile longitudinal surveys) were collected using a differential global positioning system(DGPS). The DGPS position and time accuracy is based on signals received from satellites and radio transmitters (O'Neill et al. 1996). Time is based on the satellite's atomic clock and thus is very accurate. The survey validation accuracy listed below is the accuracy of the time logged with each instrument measurement.

The resulting locations are generally accurate to within 2 to 3 m. The manufacturer's specified absolute accuracy for DGPS is a range, e.g., 1 to 5 m (root mean square). As an assurance that any one ofthe DGPS systems was not malfunctioning a field test was performed.

The protocol is presented in Appendix H.The following table presents both the manufacturer's specified accuracy and the on-site validation accuracy for the DGPS equipment.

Site-specific characteristics were also considered to assure proper equipment installation. This included testing of sediment composition to determine appropriate bottom mooring installation (anchor deployment).

Field deployments were conducted according to a predefined procedure for each instrument.

All appropriate data such as serial number, deployment position, date, time, etc., were recorded in field notes and retained as meta-data. Similar records were kept during equipment recovery to log appropriate data, including any anomalies noted during the recovery.Data Handling and Inspection.

Data collected by shipboard survey instruments (i.e., CTDs, thermistors, fluorometers, and ADCPs) were downloaded to the hard drives of laptop PCs in real time. Data collected by in situ instruments (i.e., mooring-attached meters, bottom-mounted ADCP, and tide gauges) were downloaded to laptop PCs immediately following retrieval of the instruments.

Raw data stored on the laptop hard drives were periodically copied to floppy diskettes.

All raw data, stored on the laptops and the floppy diskettes (write-protected), were transferred to the data manager. The data manager compared the contents of the floppydiskettes with the files on the laptops to assure that the complete data set had been retrieved from the laptops.Data logs were kept to record the detailed raw data origins and file locations.

A separate data log was completed for each survey component. Upon completion of the data logs, all raw data were copied from the floppy diskettes to one tabletop PC, which was used to reduce and process the raw data. In addition, the entire set of data was backed up to 26 PSE&G Permit Application 4 %larch 19)9 Exhibit E-1-3 magnetic tape. The floppy diskettes were then stored, with a copy of the data logs, in a se. xre location at LMS' office.I.A.2.c. Dye Injection The overall purpose of the dye plume survey operations was to acquire data to assist in evaluation of the advective, dispersive, and mixing processes affecting the Station'sthermal discharge to the Delaware River.The dye plume survey operations involved two elements:

(1) the land-side operationsthat control the injection of the dye and monitor dye concentrations in the cooling water system; and (2) the shipboard operations that monitor the movement and mixing of the dye in the receiving waters. The land-side element is described in this section; the shipboard dye measurements are described in Section I.A.2.d.The land-side operations involved injecting the Rhodamine WT dye (20% solution) into the cooling water-system, controlling the rate of injection, and monitoring the dye concentrations within the cooling water system. Rhodamine WT dye, routinely used in this type of survey, is non-toxic at the concentrations used. The rate of dye injection was set so that the discharge dye concentration was below visible range, at approximately 7.5 ppb.As shown in Figures 10-3 and 10-4, dye injection occurred .a the Station pump house, with sampling in the condenser building (also referred to as the turbine building) (Figure 10-5). Each injection system injected dye at a fixed rate into the intake bell of one pump in each pump pair, as shown in Figure 10-3. An automated dye sampling system was assembled in each condenser building. This sampling system allowed confirmation of the planned injection dye concentrations, estimation of the flows from the pumps receiving the dye, and measurements of the fluorescence of the intake water before dye was injected(from the pump not receiving dye). When distinguished from background fluorescence, the intake water fluorescence provides a measure of cooling water recirculation.

The dye sampling system in the chlorine sampling building was used to measure the dye.concentrations discharged to the river and the flows from the pumps not receiving dye. A mass balance of the two intake lines that merge (as shown in Figure 10-3) is solved to calculate the flow from Pump B based on the measured mass rate of dye injection and dye concentration at three sampling points.Tests of the dye injection and discharge sampling systems were performed on 29 and 30 April and on 21 and 22 May 1998 to evaluate proposed system operations and, if necessary, to make modifications prior to the full-scale deployment.

The equipment was deployed at one intake and discharge location for brief test periods; it functioned properly.Dye Injection Systems at Salem Pump House. Dye injection pumps, dye reservoirs, digital scales, and computerized recording and control systems were deployed in the 327 PSE&G Permit Applicauon 4 March 1999 Exhibit E-l-3 Salem pump house. The injection system was set up to inject dye at a fixed rate into the intake bell of one pump in each pump pair, as shown in Figure 10-4.Salem's Circulating Water System consists of two units, each with six intake pumps and six sets of condensers.

One dye reservoir, digital scale, and computerized recording and control system were set up at each unit. In addition, at each unit, three injection pumps, three check-valve-pressurized rubber hoses, and three 35-ft PVC injection tubes were deployed.

A general schematic of the dye injection system for one representative unit is shown in Figure 10-4.Dye injection setup entailed the placement of a 32-gal drum of Intracid RPhodamine WT Dye (i.e., dye reservoir) on an electronic platform scale. A small pump was placed in the dye reservoir to keep the dye well mixed, thus ensuring a uniform dye concentration.

A chemical.

metering pump was used to pump dye in an exactly measured amount from the 32-gal reservoir, through 1/44-in. polyethylene tubing, through a check valve and into a Y1/2-in.-diameter pressurized rubber hose holding carier water for initial mixing.

The hose was connected to a V2-in.-diameter 35-ft-long PVC injection tube. The injection tube conveyed the dye solution to the intake bell of one pump, via the opening provided by an adjacent floor drain. The rubber hose was pressurized with house water to provide initial mixing of the concentrated dye and sufficient pressure to distribute the dye solution properly into the pump's intake bell. [The maximum flow of house or carrier water was approximately 15 gpm, which is less than 0.003% of the CWS flow that received this dyeand carrier-water mixture.] Hence, the carrier water did not alter significantly the CWS flow and total discharge to the river. The extensive turbulence at the pump's intake assured complete mixing of the dye/cooling water mixture. A laptop computer recorded date, time, and remaining weight in the reservoir.

The dye injection system was fully automated, except for the periodic refilling of the dye reservoir.

This refilling was accomplished by LMS personnel using portable 120VAC dye transfer pumps.Dye Sampling System in Each Condenser Building.

An automated water samplingsystem, fluorometer, and computerized data recording system were set up in eachcondenser building (Figure 10-5). Water was periodically drawn from the pump side of each condenser (through six valve locations in each condenser building, for a total of 12 valves). The locations where the circulating water was sampled through the 12 valves near the condensers and the dye injection points at the intake pumps are shown schematically in Figure 10-6. The specific valve identification numbers accessed for Units 1 and 2 were as follows: 28 PSE&G Permit Application 4 March 1999 Exhibit E-1-3 VALVE I.D. ASSOCIATED CONDENSER 23CW19 23A 23CW119 23B 22CW19 22A 22CW119 22B 21CW19 21A 21CWI19 21B 13CW19 13A 13CW119 13B 12CW19 12A 12CW119 12B 11CW19 11A 11CW119 11B 0 The automated sampling system was set to direct water from each pipe through the fluorometer.

The computerized data recording equipment was set up to record thefluorometer readings.

The water drawn from the condensers was wasted to the floor drains in the condenser buildings, at a maximum flow rate of approximately 5 gpm.The fluorometers used to measure dye in each condenser building were calibrated by preparing mixtures of known amounts of Rhodamine WT dye and cooling water as described in Appendix G.Dye Sampling in the Chlorine Sampling Building.

Grab samples were collected manually at the chlorine sampling point of each of the six discharge pipes (Figure 1.0-3).A sample was taken every 10 minutes, so that each of the six discharge pipes wassampled every hour during the dye injection.

During the test of the dye injection and discharge sampling systems, the turbidity of the circulating water withdrawn at the plant intake was found to be elevated at times. As elevated turbidity could interfere with fluorometer measurements, a series of fluorometer calibrations with circulating water having different levels of turbidity was performed.These fluorometer calibrations were used to quantify the reduction in fluorescence attributable to turbidity, as described in Section I.A.3.d.29 S PSE&G Permit Apphcaiion 4 March N99 Exhibit E-I -3 L.A.2.d. Mobile Survey Five survey boats were navigated along transects in the Delaware River; the planned transects are shown in Figure 10-7. Boat number 3 measured the thermal plume in the region surrounding the discharge; this is referred to as the "rover boat".

The five boats covered regions that span specific distances (upstream of the station is positive) from the Salem discharge:

Boat Number 1 +2.5 to +6 miles Boat Number 2 0 to +2.5 miles Boat Number 3 +1 to -1 miles Boat Number 4 0 to -3.5 miles Boat Number 5 -3.5 to -6 milesEach boat was equipped with a differential global positioning system (DGPS), a fluorometer, a conductivity/temperature/depth profiler (CTD), and a personal computer (PC) to record the data; three of the boats were also equipped with an Acoustic Doppler Current Profiler (ADCP).

The configuration of the measurement equipment and the power supplies is shown schematically in Figure 10-8. An ADCP measures and records a profile of water currents at discrete vertical intervals between the surface and the bottomusing underwater acoustic technology.

A CTD, when lowered and raised to and from the bottom, measures and records the water conductivity, temperature, and depth of the instrument at frequent intervals; salinity is computed from the observed conductivity and temperature using a standard formula (Appendix B). A fluorometer measures the fluorescence, which is related to dye concentration, of river water withdrawn through a hose and passed through the instrument.

The DGPS makes use of radio positioning information transmitted by U.S. Department of Defense satellites and by U.S. Coast Guard radio beacons to geographically position the receiver, typically to within 2 to 3 m.DGPS positions are updated roughly every 2 sec.The general two-step sampling procedure entailed:

(1) temperature, conductivity (salinity), and dye fluorescence measurements at a depth of 1 to 2 ft (near water surface)as the boat traveled along the transects; and (2) vertical profiles of temperature, salinity, and fluorescence at a number of locations.

Three boats (Boats 1, 2, and 3) were also equipped with fast-response Thermistor Temperature Modules (TTM). All boats measured temperature as the boats were underway along the transect. The TTMequipment allowed more frequent measurements (compared to the CTD), particularly in the vicinity of the discharge, where higher spatial temperature gradients were expected.The CTD was lowered at vertical profiling stations from all five boats, and recorded data from the water surface to the bottom.30 PSE&G Permit Application 4 March 1999 Exhibit E-I-3 Fluorometers were used to measure dye fluorescence and thereby track the plant discharge as it mixes with the river. The fluorometers on three boats (Boats 1, 2, and 3)operated in a flow-through mode by withdrawing river water through a 3/4-in.-diameter hose using an onboard pump. The travel time of the water in the hose is computed subsequently using the pump flow rate and hose dimensions to adjust the time of fluorometer measurement to the time when the water was withdrawn into the hose. Insitu fluorometers on Boats 4 and 5 measured the fluorescence of the river water passing through the instrument which was submerged aside the boats. All fluorometer readings were then adjusted to reference temperature and used to compute dye concentration as described in Appendix G. Background fluorescence in the Delaware River was measured on 26 May 1998 (namely, the day before the dye injection started) in the vicinity of the Salem discharge.

The background fluorescence boat traversed the river between approximately R.M 58 and RM 45 as shown in Figure 10-9 and fluorometer readings, temperature, and salinity near the water surface were measured and recorded.

Vertical profiles were also measured and recorded at 10 locations.

LA.2.e. Mooring Stations Thirty-one (31) stations in the river and at the mouths of three tributaries were equipped with moorings as shown in Figure 10-10. The constituents measured at these stations varied as follows: Temperature, conductivity, and DO -five moorings (same as ambient and 1-Unit survey stations).

Temperature and conductivity

-nine moorings Temperature only -17 moorings The specific sensors for temperature and/or conductivity/DO deployed at surface, mid-depth, and bottom positions for each mooring station are listed in Table 10-2.The moorings, which were configured as shown in Figure 10-11, were deployed between 7 and 15 May 1998 and recovered generally after 4 June 1998.LA.2f Tides and Currents Tide gauges were installed by LMS at four stations along the Delaware River:* Lewes* Woodland Beach (near Ship John Shoal)* Salem Barge Slip* Western C&D Canal In addition, NOAA has continuously recording tide gauges at four locations

-Cape May, Lewes, Reedy Point, and Philadelphia. The CTD meter deployed by LMS at Lewes obtained salinity data, whereas NOAA was not obtaining conductivity/temperature data during the 2-Unit survey period. USGS has a continuously recording tide gauge at 31 PSE&G Permit Application

-. March lQ99 Exhibit E-1-3 Burlington, New Jersey (RM 121), and these data are also presented subsequently in Section I.A.3.j. The locations of the nine tide gauging stations are shown in Figure 10-12. The pressure recorded by LMS's meters was converted to excess pressure by subtracting the atmospheric pressure using the barometric pressure data from Wilmington Airport.An ADCP was deployed by divers at the station shown in Figure 10-13 on 11 May 1998.The ADCP was retrieved on 3 June 1998. The three stations occupied for the tidal boundary survey component are shown on Figure 10-14.I.A.2.g. Longitudinal Surveys The hydrothermal models of the Delaware River require data on initial conditions.

Theinitial conditions for the survey period were measured on 21 May 1998, using two boats.Conductivity (salinity) and temperature were measured throughout the water column at 17 locations along the navigation channel from the Delaware River mouth to Trenton.The river mile locations, which are based on DRBC's referencings, are: 0, 10, 20, 30, 40, 45, 50, 55, 60, 65, 70, 80, 90, 100, 110, 120, and 130 (Figure 10-15). Lateral stations on the left and right sides of the navigational channel were monitored at six river miles: 40, 50,-70, 90, 110, and 130. CTD units made by Falmouth Scientific, Inc. (FSI), were used on both boats. One boat covered from the river mouth to a station between RM 40 and RM 60, and the other boat covered the remaining extent to RM 130.Longitudinal surveys were also performed on 27 May 1998, which was two days prior to the mobile survey, and on 2 June 1998, which was three days following the mobile survey. The third longitudinal survey (2 June) also entailed continuous measurements of the surface water temperature along the navigational channel. An additional boat was used for this survey. The third boat covered the river between RM 35 and RM 70, suchthat the first and second boats covered the remainder of their previous extents. The three boats measured temperature while traveling along the channel between stations.I.A.2.h. Marsh MouthThree tributaries of the Delaware River (i.e., Mad Horse Creek, Hope Creek, and Alloway Creek) were also monitored during the 2-Unit survey (Figure 10-16). Hope and Mad Horse Creeks were surveyed on 30 May 1998; however, an engine problem with one ofthe survey boats precluded monitoring of Alloway Creek on this day. The survey of Alloway Creek was rescheduled along with a second survey of Hope Creek to provide measurements for addressing the temporal variation between the first and second marsh surveys. The survey of Alloway Creek and the second survey of Hope Creek were performed on 29 June 1998, when the predicted times and amplitudes of high and low waters were similar to those on 30 May 1998.I.A.2.i. Infrared Aerial Photography Infrared aerial images of the Delaware River were acquired at four tidal phases on the day of the mobile river survey, 29 May 1998. The area covered by the photography was 32 PSE&G Permit Applicanion 4 March 1999 Exhibit E-I-3 approximately 1,000 meters square, with a spatial resolution of 3 meters (Figure 10-17).The single-band thermal images show relative temperature at the water surface.I.A.2j. Data Collected by Others NOAA, USGS, and PSE&G were also contacted to obtain data they collected concurrently with the 2-Unit survey. The freshwater flow of the Delaware River at Trenton, New Jersey (USGS Gauge No.

01463500), and the Schuylkill River at Philadelphia (USGS Gauge No. 01474500), are used to specify freshwater flow input data for the model. Data on air temperature, barometric pressure, cloud cover, wind speed and direction, and precipitation from the PSE&G Artificial Island meteorological station and dew point temperature from Wilmington Airport are also used for modeling.LA.3. RESULTSl.A.3.a. Overview of DataThe data recorded during the 2-Unit intensive survey were downloaded and compiled in a computerized database (Paradox Version 8). The quantity and quality of the data collected within each survey component were compared to the requirements of the modified TMP. The objectives of the data collection were reviewed in instances when the recoverable data were less than the planned data collection.

Certain data to be collected at some moorings were not recovered primarily because instruments were lost*or displaced.

In addition, certain instruments stopped logging data prior to the intensivemobile survey.

However, data collected by these instruments that stopped logging were found to be useful for calibrating the model because the period of the simulation overlapped with the period of recovered data. Additional field surveys were performed to obtain certain missing data. For example, as explained in Section I.A.2.h, the marsh survey plan was modified because of an engine problem on one of the two boats. A second marsh survey was performed to obtain data on Alloway Creek, which was incompletely sampled during the first survey and to obtain additional data on Hope Creek.The total number of data records, defined as single time of measurement of one or more constituents (e.g., temperature), collected during the 2-Unit survey was 1,271,823 (Table.10-3). This tabulation provides a means of showing the relative distribution of measurements during the intensive survey and a comparison of the 2-Unit survey to the ambient and I-Unit surveys (PSE&G 1986b) and the six-month mooring monitoring (Section I.B.3.b).LA.3.b. Quality Assurance/Quality Control (QA/QC)The results of the testing of meters as described in Section I.A.2.b are summarized.

Temperature

-Temperature meters uscd on moorings were initially tested prior to deployment in the river. Sixty-eight (68) of the 79 meters tested (namely, 86%) were within the 0.2°C tolerance of the water bath temperature measured using a certified thermometer (Table 10-4). The other 11 meters showed maximum deviations at any of 33 PSE&G Permit .\ppilcation 4 March 199Q Exhibit E-I-1 the four temperatures tested that ranged from +/-0.2 0 C to +/-1.69'C, as shown Table 10-5.The expected (certified) temperature (T) was regressed against the meter temperature (Tmeas), and the resulting regression equations are shown in Table 10-6. The correlation for all regressions was high, as reflected by the r 2 values that exceeded 0.997. These regressions were used to adjust the temperature recorded by each of the I I nonconforming meters, so that the data presented in this report have been corrected according to the QA/QC plan.The moored temperature instruments were also tested following the 2-Unit survey, except for seven instruments that were downloaded, redeployed, and then never recovered.

The temperatures for the 1 meters for which regressions were developed were adjusted (by applying the regression equations in Table 10-6) and then compared to the standard.

The results of the post-survey testing of 72 temperature meters are summarized in Table 10-7.Fifty-six (56) of the 72 meters (78%) were within the 0.2°C tolerance at all temperatures tested. The other 16 meters showed maximum deviation at any temperature that ranged from +/-0.2°C to +/-+1.2°C. The nine shipboard instruments used during the mobile and longitudinal surveys were tested before and after the 2-Unit survey. The pre- and post-survey calibrations were done by testing the meters alongside an FSI standard electronic thermometer and a selected thermistor (Meter 1388). The pre-survey tests, which were performed at temperatures of 15, 22, and 30'C, resulted in all three thermistors and five CTD meters being within the 0.05°C tolerance of the FSI standard and all CTD meters and two thermistors being within the same tolerance of Meter 1388 (Table 10-8). The post-survey test, which was performed at the same three temperatures and at up to two additional temperatures (0 and 7.5°C), found all instruments except one thermistor withinthe specified 0.02'C tolerance of both the FSI standard and Meter 1388. A constant temperature adjustment equivalent to the average of the pre- and post-survey differences 0 for Meter 1386 was considered reasonable.

The one thermistor (Meter 1386) that exceeded the tolerance limit had post-survey measurements' that were between 0.12'C and 0. 14TC lower than the Falmouth standard and Meter 1388. The temperature measurements recorded with Meter 1386 were adjusted by adding 0.07°C (a constant) to all survey data. The adjusted temperature data collected with Meter 1386 are therefore stated to be within 0.07°C of the actual river temperature.

Meter 1386 was used on mobile survey Boat 2, which covered the river between the Station discharge and approximately

2.5 miles

upstream of it. This thermistor was also used to measure thesurface water temperature during the second longitudinal survey. Because seven of the eight (88%) shipboard thermistors passed pre- and post-survey calibrations and the one thermistor (Meter 1386) that "drifted" out of tolerance prior to the post-survey testing needed a relatively minor adjustment, the overall water surface temperature data recorded by shipboard thermistors are considered to be accurate for the hydrothermal assessment.

Salinity/Conductivity

-A combined total of 30 CT and CTD meters, which were used at moorings, were calibrated for conductivity/salinity measurements as described in SectionI.A.2.b. These meters were retrieved after the 2-Unit survey and tested for accuracy within the tolerance level of 1.0 ppt. According to the post-survey testing, 28 of the 30 meters (93%) were within the 1.0-ppt tolerance of the "known" salinity at all tested 34 PSE&G Permit .-pplicatnon 4 March 1999 Exhibit E-1-3 salinities (Table 10-9). The CT meter at M12 surface had a maximum difference of 1.44 ppt at a salinity of 15.62 ppt, and the CT meter at 6 surface had a maximum difference of 1.93 ppt at a salinity of 25.88 ppt. No adjustment to the conductivity/salinity data was made because the tolerances were exceeded at only one or two of the five salinities tested, and these salinities were generally greater than the salinity of the river water at the designated mooring as measured by shipboard CT meters.

Dissolved Oxygen -As stated in Section I.A.2.b, the CT/DO meters deployed at 10 moorings were calibrated prior to the survey to attain an accurate measurement of the DO saturation concentration.

Therefore, pre-survey testing results in no difference between the meter reading and the known DO concentration.

The meters were returned to LMS's laboratory after the survey, and tested using the saturated air method. Only one of the 10 (10%) CT/DO meters was within the specified DO tolerance of 0.4 mg/l (TablelO-10).

Five of the meters were found to measure DO within 1.0 mg/1 of the saturated air concentration.

Another three meters were between 1.0 and 1.7 mg/l of the saturated DO concentration.

The CT/DO meter at the bottom of mooring 1 showed a DO that was 8.6 mg/l greater than the saturated air concentration.

As the difference in DO at saturation may not be indicative of the differences, if any, at the river DO levels which are generally below saturation, no adjustment to the data recorded was made. The "drifting" of DO meters during a two-week period is fairly common because the probe membrane gets fouled. To overcome these difficulties, DO measurements were repeated at three mooring locations

-Mad Horse Creek (surface), 21 (surface and mid-depth), and 9M (surface and mid-depth)

-during September and early October 1998.Depth/Pressure

-The four water depth/pressure sensor devices used to record water levels at LMS's four tide-gauging stations were initially tested by the Coastal Leasing of Cambridge, Massachusetts.

The maximum difference in depth was found to be within 0.2 m (0.6 ft) of the actual depth. In addition, the MicroTide meters deployed at the Salem Barge Slip and Woodland Beach stations and the MicroCTDs deployed at the western C&D canal and Lewes stations were tested in the field, as described in Section I.A.2.b. The results are summarized below: DEPTH (ft)STATION STEEL TAPE INSTRUMENT DIFFERENCE Salem Barge 4.13 4.29 0.16 2.04 2.15 0.11 Woodland Beach 5.31 5.34 0.03 Western C&D 2.94 2.79 -0.15 Lewes 5.14 5.13 -0.01 All depth measurement instruments used at tide gauging stations were found through field testing to be within the 0.2-m (0.6-ft) tolerance limit.*35 PSE&G Permit Application-L March 1999 Exhibit E-1-3 The calibration/validation testing results for the equipment used to measure temperature, salinity/conductivity, DO, and depth/pressure are summarized in Table 10-1. 11 Velocity -As stated in Section I.A.2.b, the bottom ADCP was calibrated for compass direction prior to deployment.

The ADCP units used on boats were tested in the river prior to the mobile survey to check that the real-time display of velocities were as expected for the tidal phase. The bottom ADCP data were initially downloaded approximately 30 min after deployment to check the data.

All data viewed on the boat ADCP units and downloaded from the bottom ADCP unit appeared to be reasonable.Subsequently, bottom ADCP data were downloaded during the deployment period and found to be reasonable.

Dye Injection

-The electronic scales for the dye injected into the Salem discharge were calibrated by Advance Balance Service Co. on 8 May 1998. All seven fluorometers were calibrated on 20 May 1998; the results of the regression analysis are presented in, Appendix G.Position and Time -Positioning instruments were field-validated according to the procedures outlined in Appendix H of the QA/QC plan.

Each boat was positioned adjacent to a piling at the Delaware City Marina and the DGPS-displayed coordinates were recorded.All data-logging computer clocks were synchronized with the atomic time-scale operated by the National Institute of Standards and Technology (NIST) just prior to the survey.Using a direct modem connection to one of the time servers operated by NIST, and the"NISTIMEW" program, the computer clocks were. automatically synchronized with the NIST time standard.

The accuracy of this time setting is plus or minus one second.I.A.3.c. Longitudinal Surveys The data collected during the longitudinal surveys are presented graphically in a series of figures that show the station location and time of measurements.

The vertical profiles of temperature and salinity at 17 stations along the channel of the river and lateral positionsat six river miles (40, 50, 70, 90, 110, and 130) for the first longitudinal survey (21 May 1998) are shown in the following figures: 36 0 PSE&G Permit Apphcation 4 March 1999 Exhibit E-1-3 TEMPERATURE SALINITY 10-18 10-21 10-19 10-22 10-20 10-23The vertical profiles of temperature and salinity for the second longitudinal survey performed on 27 May 1998 are presented in figures: TEMPERATURE SALINITY 10-24 10-27 10-25 10-28 10-26 10-29The results of the third longitudinal survey (2 June 1998) are similarly presented in these figures: TEMPERATURE SALINITY 10-30 10-33 10-31 10-34 10-32 10-35 The raw data representing surface temperature of the river measured during longitudinal survey 3 is shown in Figure 10-36.I.A.3.d. Dye Concentrations in Plant Discharge The dye concentration of the plant flow was measured (as described in Section I.A.2.c) in both the condenser/turbine building and in the chlorine sampling building.

The, range of the correlation coefficient (r 2), a statistical measurement commonly employed to quantify the linear relationship between two variables (in this case fluorescence and dye concentration), was from 0.99436 to 0.99999 for the regressions (r 2 = 1 represents a"perfect" fit). Calibration data and regression results are presented in Appendix G. Raw fluorescence units (RFU) measured using fluoromreters were found to be affected by the turbidity of the intake water. Seven (7) fluorometer calibrations were performed using seven samples of intake water that ranged from 20 to 215 nephelometric turbidity units (NTU). The dye fluorescence readings were lower than the prepared dye concentration because of turbidity interference (i.e., particulates blocking fluorescence from reaching the sensor). The percent reduction in RFU was related to turbidity through the following linear regression analysis (Figure 10-3 7):% Reduction = 0.1271 .Turbidity (r 2= 0.979; n = 8)where 37 PSE&G Permit Application 4 March 1999 Exhibit E-1-3 turbidity is in units of NTU The dye concentration, therefore, was corrected for turbidity.

Samples of the circulating water and the combined circulating and service water were collected at 0.5-hr intervals and analyzed for turbidity at the chlorine sampling building.

The dye concentration based on RFU readings (C,) was adjusted for turbidity by the percent reduction

(%R)attributable to turbidity in computing the adjusted dye concentration (Ca): Ca -(I-%R)The fluorometer and turbidity measurements at the six discharge pipes (i.e., discharge pipes) are presented first to show the dye concentration of the Station discharge.

TheRFU and dye concentrations of the circulating water as measured in the condenser/turbine building are presented subsequently to show the recirculation of water from the discharge to the intake.The RFU, turbidity, and dye concentration (with and without the turbidity adjustment) in the six discharge pipes (identified in the NJPDES permit as Discharge Serial Numbers[DSN], shown in Figure 10-6) measured at the chlorine sampling point are shown for the period when dye was injected into the CWS in the following figures: DISCHARGE PIPE DSN FIGURE 11 481 10-38 12 482 10-39 13 483 10-40 21 484 10-41 22 485 10-42 23 486 10-43 Surges in turbidity appear to occur after EOF along with reductions in RFU readings due to turbidity. The adjusted dye concentration, labeled as "dye' (w/turb)," at the discharge pipes was approximately 7.5 ppb during the injection period which started at 1200 hrs on.27 May and ended shortly after 1200 hrs on 29 May.The fluorometer readings and dye concentrations with and without the adjustment for turbidity are shown for the 12 circulation water intake pipes to the condensers (see Figure 10-6) in the following figures: CONDENSER CONDENSER WATER BOX No. FIGURE No. WATER BOX No. FIGURE No.11A 10-44 11B 10-45 12A 10-46 12B 10-47 13B 10-48 13A 10-49 21A 10-50 21B 10-51 22A 10-52 22B 10-53 23B 10-54 23A 10-55 38 PSE&G Permit Applicauon 4 March 1999 Exhibit E-1-3 As stated previously, the six condenser pipes on the left side of the list above received the dye injection, whereas the six condenser pipes on the right side received intake water that was not directly injected with dye. The intervals when no data are plotted for condenser pipes 11 A, I 1B, 12A, 12B, 13A, and 13B were caused by detritus in the river that clogged the intake manifolds of the sampling device. When this occurred the manifolds were cleared manually and the sampling measurements resumed.The recirculation of water from the discharge pipes to the circulating water intakes is evident in the gradually increasing dye concentration of the six condenser pipes on thefight side of the above list.

A recirculation ratio (R) is defined as the dye concentration of the plant intake (C 1) divided by the dye concentration of the plant discharge (Cd). For example a recirculation ratio of 0.1 is equivalent to stating that the dye concentration measured at the intake is 10% of the concurrently measured dye concentration at the discharge pipes.The average of the data for the six intake pipes and six discharge pipes during 1-hr increments were used to compute the hourly average recirculation ratio (Figure 10-56).Recirculation varied with tidal phase: the dye was relatively concentrated at the intake during slack phases and relatively dilute during the flood and ebb phases. A 12-hr running average recirculation ratio shows the cumulative increase in the dye concentration of the intake relative to the fairly constant discharge dye concentration.

I.A.3.e. Mobile Survey Results The measurements taken during the mobile survey of the Delaware River on 29 May are presented as surface temperature contour plots and as vertical profiles, as well as surface dye contour plots and vertical profiles.

The surface temperature and surface dye plots for each of the four tidal phases cover the full 12-mile extent of the river, as well as a close-up of the vicinity of the Station discharge.

The paths of the five boats that measured temperature and dye in the river during a 2-hr interval for each tidal phase are plotted.The sixteen figures showing surface temperatures or dye concentration are as follows: TEMPERATURE DYE TRANSECT FULL STATION FULL STATION LOCATIONS EXTENT PROXIMITY EXTENT PROXIMITY Ebb 10-57 10-58 10-59 10-60 10-61 EOE 10-62 10-63 10-64 10-65 10-66 Flood 10-67 10-68 10-69 10-70 10-71 EOF 10-72 10-73 10-74 10-75 10-76The temperature and dye concentrations measured by each boat were compared in two ways to assure data consistency.

First, intraboat comparisons of the measurements along horizontal transects to vertical profile measurements taken within close proximity and thesame tidal phase were made. Second, interboat comparisons of measurements alonghorizontal transects and vertical profiles by a boat to measurements along horizontal transects and vertical profiles by an adjacent boat within close proximity and the sametidal phase were made. The intra- and interboat comparisons for Boat 3 showed inconsistent dye concentrations measured along horizontal transects; however, the.3 39 PSE&G Permit Application 4 March 1999 Exhibit E-1-3 vertical profile measurements of dye concentrations were consistent with data collected by Boats 2 and 4. This inconsistency for Boat 3 indicates that the sampling hose for horizontal transects contained dye that was desorbed by the water passing through it. Dye concentration measurements along horizontal transects covered by Boat 3 were removed from the data compiled for contour plotting.

This is the reason for the blank areas where dye data are missing in Figures 10-60, 10-61, 10-65, and 10-66.The vertical profiles of temperature, salinity, and dye concentration have been made into figures for each tidal phase: one figure showing location of vertical profile stations, two showing temperature profiles, two showing salinity profiles, and two showing dye profiles of representative stations.

The data collected are presented as two types of plots: vertical profiles, and temporal plots.The vertical profiles of temperature, salinity, and DO are presented as sets of eight figures for each tidal phase: three figures each of temperature and salinity profiles and two figures of DO profiles.

The 2-hr tidal phase intervals defined for the mobile survey data presentations are used for the vertical profile plots of the mooring station data. The locations of the moorings are shown in Figure 10-10.

The availability of salinity and DO data at any of the three depths can be checked by cross-referencing Table 10-2.The figures showing the time series of temperature, salinity, and DO for all 31 mooring stations are listed on the following page.40 PSE&G Permit Application 4 March Ig(Q Exhibit E-1-3 FIGURE NUMBERS FOR PLOTS OF TEMPORAL VARIATIONS IN TEMPERATURE.

Tide and Current Data Presentation of the results of the tidal boundary component, tide gauge, and the bottom-mounted ADCP current velocity measurements is discussed below.Vertical profiles of temperature and salinity at the mouth of the river are presented for three stations along the model boundary transect.

Plots of temperature and salinity at five time intervals during flood tide are shown in Figures10-189 and 10-190, respectively.

The water surface elevations measured at four tide gauge stations installed for the 2-Unit survey were converted to the common datum (NAVD) by surveying from a vertical control benchmark.

In addition, data recorded by NOAA at their four tidal gauging stations and data recorded by USGS at their tidal gauging station were also converted to NAVD and plotted. [Figure 10-12 shows the gauge locations.] The time series of water surface elevations between 19 May and 5 June 1998 at these eight stations are shown in Figures10-191 and 10-192. The time series during the mobile survey of 29 May 1998 are shown in Figures10-193 and 10-194.

The temperatures measured at four tide gauges -Salem Woodland Beach, Lewes, and western C&D canal -during the two-week period and on the day of the mobile survey are shown in Figures10-195 and 10-196, respectively.

During low tide, the tide gauge atWoodland Beach was temporarily exposed and consequently could not measure water depth as noted in Figures10-191 and 10-193. The salinity at two of these stations, namely Lewes and western C&D canal, during the two-week period and on the day of the mobile survey is shown in Figures10-197 and 10-198, respectively.The average and minimum/maximum range in tide between high and low water are shown for the 17-day period in Figure 10-199 and the same tidal characteristics for the day of the intensive mobile survey, 29 May 1998, are shown similarly in Figure 10-200.The tidal time delay, or phase lag from the mouth upstream to Philadelphia, is shown.The current speed and direction measured by the bottom-mounted ADCP during the 19 May to 4 June period and then averaged over three one-foot depth intervals are shown in Figure 10-201 and 10-202. The time increment for these measurements is 2.5 min. As stated in Section I.A.2.f, the velocity of the Delaware River was measured at three transects using ADCP instruments aboard boats. The longitudinal velocities (i.e., perpendicular to the river cross section) are shown in the contour plots for the four tidal phases on 29 May 1998: TIDAL PHASE FIGURE No.Ebb 10-203 EOE 10-204 Flood 10-205 EOF 10-206 42 PSE&G Permit Application 4 March 1999 Exhibit E-1-3 I.A.3.h. Marsh Mouth Data The marsh survey began as planned on the morning of 30 May 1998. The surveys atHope Creek and Mad Horse Creek were completed.

However, halfway through the survey (i.e., after the flood tidal phase) at Alloway Creek, equipment failed and no datawere collected during ebb tide. The survey of Alloway Creek was redone during similartidal conditions on 29 June 1998. Hope Creek was also surveyed to observe any temporalvariations between the earlier and later marsh surveys and thereby infer whether thecomplete Alloway Creek survey was similar to conditions on 30 May 1998. Thetemperature, salinity and dye data recorded during the marsh mouth survey are presented as vertical profiles.

These data are shown graphically in Figure 10-224.Hourly precipitation data also collected at PSE&G's monitoring station show rainfall on these days, preceding and during the survey period, as follows: DAY IN 1998 RAINFALL (in.)May 1 0.54 3 0.42 4 0.08 6 0.08 7 0.04 8 3.63 9 1.54 10 0.96 11 1.33 12 2.83 29 0.08 June 1 1.79 2 0.13 3 0.08 The USGS-gauged flow in the Delaware River at Trenton increased to a peak of approximately 70,000 cfs on 11 May 1998 and then decreased to approximately 10,000 cfs during the 2-Unit survey period (Figure 10-225). The USGS-gauged flow in the Schuylkill River at Philadelphia is also shown in this figure.44 PSE&G Permit Application 4 March 1999 Exhibit E-1-3 I.B. Six Month Moorings for Thermal Monitoring I.B.1. Objectives The 2-Unit survey continued from June through early November 1998, primarily to collect additional temperature data during seasonally varying conditions. Both power-generating units at Salem were operating throughout the six-month monitoring period except between 26 July and 8 August 1998, when Unit 2 was not operating.

Moorings equipped with thermistors were deployed at 10 stations in the Delaware River and at the mouths of two tributaries. The work plan for this monitoring was described in the Modified TMP (1998).In addition, DO and salinity were measured at three mooring stations from 3 September through 8 October 1998 to collect data under temperature conditions higher than those of the intensive survey.LB.2. Methods and Materials The methods and materials for the six-month monitoring were generally similar to those for the 2-Unit survey. The following sections reference the previously described methods and focus on any procedures that were initiated for the extended monitoring.

LB.2.a. Quality Assurance/Quality Control (QA/QC)Based on the experience of the 2-Unit intensive survey, additional steps were taken to assure the completeness, accuracy, and precision of the continued monitoring. First, one temperature meter and one backup meter (all Onset thermistors) were deployed at each sensor depth (surface, mid-depth, and bottom). Second, the temperature meters were retrieved periodically and tested after retrieval, as described in Section I.A.2.b. Pre-deployment testing was also performed. Third, CT/DO meters (YSI 6000 series) were tested approximately every two weeks by sampling river water adjacent to each meter and analyzing the DO by Winkler titration in addition to pre- and post-deployment testing, as described below.Temperature The thermistors deployed at moorings were tested in four different water baths, as described in Section I.A.2.b. Thermistorsthat did not read within 0.2"C of the certified thermometer at any of the four temperatures prior to the survey were analyzed by a regression analysis.

These regressions were used to adjust the temperature recorded by each of the nonconforming meters for the deployment period.All thermistors were retrieved after approximately one month of monitoring and replaced by another set of thermistors on the moorings.

The retrieved thermistors were tested again (i.e., post-deployment) and the pre- and post-deployment tests are presented in Section I.B.3.a. The post-survey testing for one deployment period served as the pre-survey testing of those thermistors for their subsequent deployment as the thermistorswere only stored at LMS's laboratory during the interim.45 PSE&G Permit Application 4 March 1999 Exhibit E- 1 -3 Dissolved oxygen. The quality assurance/quality control (QA/QC) procedures employed I for the DO measurements between 3 September and 8 October 1998 are described in Exhibit E 1. There were pre- and post-deployment tests for the two sequential deployments that spanned the monitoring period.I.B.2.b. Temperature The mooring stations that were equipped with thermistors are shown in Figure 10-226.Nine of the moorings had thermistors at three depths using a configuration similar to thatused for the intensive survey (as shown in Figure 10-11), and the mooring station in the Salem River, which is locally shallow, had thermistors just below the water surface (Table 10-12). As two thermistors were set at each depth, there were a total of 56 thermistors in the river, except during the beginning of the extended monitoring period (4 June to 28 July 1998), as explained below.Five mooring stations (21, 22, 23, 24, 9M) remained in service following the end of the 2-Unit intensive survey on 4 June 1998. Dual thermistors were deployed at all stations between 19 June and 28 July 1998, as listed in Table 10-12. (The two surface thermistors are referred to as "a" and "b," mid-depth as "c" and "d," and bottom as "e" and "f'; lower and upper are used interchangeably.)

All thermistors were retrieved on 28 July, and a full set of 56 thermistors were deployed that day. All 56 thermistors were retrieved and replaced with other thermistors on 2 September, and 7 October 1998. The thermistorswere retrieved on 5 November 1998, when the six-month thermal monitoring ended. The data recorded on each thermistor were downloaded and transferred to the database.LB.2.c. Dissolved Oxygen 0 CT/DO meters were installed by Woods Hole Group on 3 September 1998 at Mad Horse Creek (surface) and Station 211 (surface and mid-depth), and on 4 September at Station 9M (surface and mid-depth).

The meters were downloaded on 17 September and samples collected near the meters were analyzed for DO by Winkler titration for QC. The meters were redeployed on 17 September and continued monitoring until 8 October 1998. Themeters were retrieved on 8 October 1998, and the data were downloaded and transferred to the database.LB.3. Results I.B.3.a. Quality Assurance/Quality Control (QA/QC)The results of the testing of thermistors are presented as a series of deployment periods.Four tables summarize the temperature testing results for each deployment period except for the 20-28 July 1998 deployment, as described below.

Eighteen (18) of the 24 thermistors tested (i.e., 75%) prior to deployment were within the 0.2°C tolerance of the water bath temperature measured using a certified thermometer (Table 10-13). The other six thermistors showed the absolute value of maximum deviations at any of the four Table 10-14. The expected (certified) temperature (T) was regressed against the meter temperature (T.as), and the resulting regression equations for these six thermistors are shown in Table 10-15. These regressions were used to adjust the temperature recorded by each of the temperatures tested that ranged from 0.2 1°C and 1.70°C, as shown in six nonconforming meters, so that the data presented in this report have been corrected according to the QA/QC plan. These 24 thermistors were also tested following the retrieval on 28 July 1998. The post-survey readings of all thermistors in the water baths were compared first to the certified thermometer, and all 24 thermistors (100%) were within the accuracy tolerance of 0.2°C (Table 10-14). Only four of the six thermistors adjusted based on regressions were outside the 0.2°C tolerance at any temperature tested. The results of the post-survey testing of 24 thermistors are summarized in Table 10-16. Twenty of the 24 meters (83%)were within the 0.2°C tolerance at all temperatures tested. The other four meters showed maximum deviation at any temperature that ranged from _+0.2°C to +/-I.0 0 C.2 July -28 July 1998. Sixteen (16) of the 18 thermistors tested (89%) prior to deployment were within the accuracy tolerance of 0.2°C (Table 10-17). The other two thermistors showed the absolute value of maximum deviations at any temperature between 0.21°C and 0.27°C (Table 10-18). Regression analysis was performed for these two thermistors (Table 10-19), and the data recorded by these two nonconforming meters were adjusted.

The post-deployment testing of the 18 thermistors resulted in 12 thermistors (67%) being within the accuracy tolerance of 0.2*C at all four temperatures (Table 10-18). The adjustment of the two thermistors based on regressions yielded similar differences from the certified thermometer as compared to the unadjusted temperature readings. The post-deployment testing, which is summarized in Table 10-20, showed 67% of the thermistors within the 0.2°C tolerance and maximum deviations in the other six thermistors that ranged from +/-0.2°C to +/-1.2*C.20 July -28 July 1998. All eight of the thermistors tested-(100%)

prior to and after deployment were within the accuracy tolerance of 0.2°C.28 July -2 September 1998. Forty-eight (48) of the 56 thermistors tested (86%) prior to deployment were within the accuracy tolerance of 0.2°C (Table 10-21). Maximum deviations (absolute values) between the other eight thermistors and the certified thermometer ranged from 0.210C to 0.90*C (Table 10-22). Regressions for these eight thermistors that exceeded the accuracy tolerance were developed and applied to the data collected (Table 10-23). Post-deployment testing, which was done at temperatures of 0°C, 25°C, and 30*C (not at 37*C), showed 52 thermistors out of 56 (93%) were within the tolerance without any adjustment (Table 10-22). The adjustment of eight thermistors based on regressions resulted in five of these thermistors being within the tolerance.

The post-deployment testing, which is summarized in Table 10-24, resulted in 89% of the 47 PSE&G Permit Application 4 March 1999 Exhibit E- 1 -3 thermistors being within the 0.2'C tolerance, and maximum deviations in the other sixthermistors ranged from +/-0.2°C to +/-0.7'C.2 September

-7 October 1998. Forty-nine (49) of the 56 thermistors tested (88%)

prior to deployment were within the accuracy tolerance of 0.2°C (Table 10-25). The other seven thermistors showed absolute value maximum deviations at any temperature between 0.23 0 C and 1.1 6*C (Table 10-26). Regressions for these seven thermistors that exceeded the accuracy tolerance were developed and applied to the data collected (Table 10-27). Post-deployment testing of the 56 thermistors resulted in 49 of the 56 thermistors (88%) being within the tolerance without any adjustment (Table 10-26). The adjustment of seven thermistors based on regressions yielded four of these thermistors being within the 0.2°C tolerance.

The post-deployment testing showed 89% of the thermistors were within the 0.2°C tolerance, and the maximum deviation ranged between _+0.20'C and+/-2.25°C (Table 10-28).7 October -5 November 1998. Fifty-one (51) of the 56 thermistors (91%) tested prior to deployment were within the accuracy tolerance of 0.2°C (Table 10-29). The other five thermistors showed absolute value maximum deviations at any temperature between 0.23°C and 0.67'C (Table 10-30). Regressions for these five nonconforming thermistors that exceeded the accuracy tolerance were developed and applied to the data collected (Table 10-3 1). Post-deployment testing showed that 44 thermistors of the 56 (79%) were within the tolerance without any adjustment (Table I 0-30). The, adjustment of five thermistors based on regressions resulted in two of these thermistors being within thetolerance. The post-deployment testing resulted in 75% of the thermistors being within the 0.2'C tolerance, and the maximum deviations in the other 14 thermistors ranged from+/-0.2*C to +/-0.4 0 C (Table 10-32).I.B.3.b. Temperature The total number of data records, defined as a single time of measurement of one or moreconstituents (temperature), collected between 4 June and 5 November 1998 was 1,903,481.

This provides a means of showing the relative distribution of measurementsbetween the extended monitoring and the intensive survey components, as shown in Table 10-3.As stated in Section I.B.2.b, pairs of thermistors deployed on 10 moorings set in the river and at the mouths of tributaries (shown in Figure 10-226) monitored temperature.

As temperature was measured at eight (all except Salem River and G9) of these moorings during the intensive survey (as described in Section I.A.3.f), the combination of the extended monitoring and the intensive survey periods provides data for approximately six months. The intensive survey data collected by instruments at surface, mid-depth, andbottom positions were combined with the data collected during the extended period bythe primary thermistors, which are referred to as meters A (surface), C (mid-depth), and E(bottom). The backup thermistors, which were deployed between 19 June and 28 July 1998 and are referred to as meters B (surface), D (mid-depth), and F (bottom), provided 48 PSE&G Permit Avnlication 4 March 1499 Exhibit E-1-3 temperature data for most of the overall six-month period. The data collected by the primary and backup thermistors deployed at Salem River and G9 also cover periods similar to those covered by the thermistors at the other eight moorings.Temperature data are presented graphically as temporal plots having uniform time axes that begin in May and end in November 1998. The figures showing the time series of temperature for the 10 mooring stations are: PRIMARY METERS BACKUP METERS STATION (A, C, E) (B, D, F)Salem River 10-227 10-228 Mad Horse Creek 10-229 .10-230 21 10-231 10-232 22 10-233 10-234 23 10-235 10-236 249G9MM9G9 10-23710-23910-24.110-10-23810-24010-24210-24310-245 24410-246 I.B.3.c. Dissolved Oxygen As stated in Section I.B.2.c, DO was measured at three mooring stations between 3 September and 8 October 1998.

To determine whether each thermistor is operating within the required test accuracy, all moored temperature monitoring equipment is calibrated in a constant temperature calibration bath against an NIST certified thermometer, at points across the anticipated range of the temperatures being measured.

The thermistor calibration is conducted prior to and after the completion of the survey according to the following protocols:

Each thermistor, CT, and CT/DO instrument is checked in the water bath (Blue M Magni-Whirl Constant Temperature Bath or equivalent) against an NIST certified thermometer (Kessler model 171 @ 0.05'C increments or Kessler model 1714 Master Lab Thermometer

@ 0.2°C increments or equivalent) at the following temperatures:

The thermistors are placed in the primary water bath for 10 minutes to let them equilibrate before starting the calibration/validation.

The detailed procedures for the Onset thermistors and the YSI, CT, and CT/DO monitors are provided.0 Onset Optic StowAway Temp Logger: Connect the Optic Base Station to the host computer.

Slide the Optic StowAway Temp into the Optic Coupler on the Optic Base Station.

Launch'the Temp Logger and remove the logger from the Optic coupler. Place the Temp logger into the tempering bath for up to 15 minutes. Let it log data for up to 5 minutes.Record the certified thermometer readings at 1-minute intervals for final 5 minutes.95 E 1-3"??/23 Feb 99/1998110 Privileged and Confidential Prepared at the Request of Counsel In Anticipation of Litigation After the 5-minute calibration period, remove the logger and reattach it to the Optic BaseStation for downloading of the temperature data.

The logger temperature data will be compared to the certified thermometer data.This procedure is repeated for the remaining test temperatures. Temp loggers that do not read within 0.2°C of the certified thermometer, and cannot make use of an appropriate correction factor, will be removed from service and returned to the manufacturer for repair.* YSI Models 6000, 600XLM, and 6920 Multi-Parameter Water Quality MonitorsThe YSI meter functions are accessible through the Sonde menu. Using the arrow keys, highlight and select Sonde from the top-line menu. At the main menu, select 5, System Setup. Set date, time, and instrument ID number. Press escape to return to the main menu.Select Run from the main menu. The instrument is now ready to check. Following the calibration procedures outline for the Optic StowAway Temp Loggers, each YSI thermistor will be checked in the water bath against the NIST certified thermometer, downloaded, and results compared to the certified thermometer.

Thermistors that do not read within 0.2°C of the certified thermometer, and cannot make use of an appropriate correction factor, will be removed from service and returned to the manufacturer for repair.All thermistor calibration results will be recorded on a laboratory calibration sheet (see Table A-I for example).

This record will contain the serial number of each thermistor, serial number of the certified thermometer, the temperatures displayed on the certified thermometer and the thermistor being calibrated, dates on which the calibration was performed, and the name of the technician who performed the calibration checks. All calibration records will be inspected by the Quality Assurance Scientist and kept on file in the QC Department.

This procedure calibrates conductivity (uS/cm) and salinity (parts per thousand).

Place 500 mL (approximately 1 pint) of conductivity standard in a clean calibration cup.The conductivity standard will be within the conductivity range expected at the project site.Make sure that the sensor is as dry as possible prior to beginning this procedure.

Immerse the probe end of the sonde into the solution.

Gently rotate and/or move the sonde up and down to remove any bubbles from the conductivity cell. The probe must be immersed past its vent hole.Allow at least 1 minute for temperature equilibration before proceeding.

From the Main menu, select conductivity and enter the calibration value of the standard that you are using (mS/cm at 25°C) and press enter. The current values of all enabledsensors will appear on the screen and will change with time as they stabilize.

When the reading shows no significant change for over 30 seconds, press the enter key. The screen will indicate that the calibration has been accepted and prompt you to press any key to return to the calibrate menu.Rinse the sonde in cool tap water and gently dry the sonde.

After calibration the sonde is checked against 4 additional conductivity standards covering the full range of conductivities expected at the site. These checks are conducted as follows: Place 500 ml of conductivity standard in a clean calibration cup.Make sure the sensor is as clean as possible.Immerse the probe end of the sonde into the solution.

Gently rotate and!or move the sonde up and down to remove any bubbles from the cell. The probe must be immersed past its vent hole.Allow at least 1 minute for temperature equilibration before proceeding.

In addition, the air saturated water calibration is performed on all probes/meters prior to the survey. As stated in Section 10.1.2.2, the presurvey calibration entails adjustment to the instruments to attain calibration; the instrument reading during the postsurvey calibration was recorded and compared to the saturation concentration before readjusting the instrument, if necessary.

Saturated Air Chamber Calibration Procedure From the Sonde Main menu, select Calibrate:

The calibrate menu will be displayed.

Place a wet sponge inside of a clean, empty calibration cup. Place the probe end of the sonde into'the calibration cup. Allow 10 to 15 minutes to elapse so that the air in the chamber becomes saturated with water vapor and the D.O. sensor will warm up and stabilize.

Select Calibrate form the Main menu and DO% to access the DO% calibration procedure.

Enter the barometric pressure in mm of Hg, in Delaware or study area, then hit enter. The computer will indicate that the calibration procedure is in progress.After approximately 1 minute, the calibration will be complete.

Press any key, as instructed, and the screen will display the percent saturation value, which corresponds to your local barometric pressure input.Calibration of dissolved oxygen in the DO% procedure also results in the calibration of the DO (ppm) mode.Air Saturated Water Calibration Procedure (Only Done on Presurvey Calibration)

To confirm the air calibration results, the protocol for calibration using air-saturated water will be completed on 10% of the units being calibrated each day as follows: A volume of nearly air-saturated water will be set up in a container.

Three BOD bottles will be filled with this water and fixed for Winkler dissolved oxygen analysis.

Prior to drawing off the water, a DO reading will be recorded in the bucket with the water quality instrument.

If one of the values in the BOD bottles differs from the other two by than 0.5 ppm, that value will be discarded, and the remaining two values will be averaged and compared to the instrument reading. The difference between the Winkler readings and the meter will be recorded and used to calculate a correction factor when reviewing the data. Meters that differ by more than 0.5 ppm from the wets will be recalibrated and retested.All dissolved oxygen calibration results will be recorded on the laboratory calibration sheet (See Table C-I for example).

This record will contain the identification record ofeach unit, the saturated air results, any comparisons between the Winkler samples and the unit, dates on which the calibration was performed, and the name of the technician who performed the calibration.

All calibrations records will be inspected by the Quality Assurance Scientist, and kept on file in the QC Department.

It is intended to prevent use of instruments that have clearly begun to malfunction since calibration.

The basic procedure involves submerging the instrument (tide gauge) to a known depth in water and verifying that the instrument reads that depth to within acceptable limits. The factors affecting the test include: the density of the water (a function of salinity and temperature), any waves or other short-period motion of the water surface, and any error in measuring the physical depth of the instrument below the water surface.Mobile Instrument Procedure The test site will be the deployment site, which is protected from waves and wakes.Attach the instrument to a length of light chain or low-stretch dacron rope sufficient to lower the instrument to the maximum available depth at the test site. Weight the bottom of the chain or rope, to assure that it will hang vertically in the water column.Tension the chain or rope; then use a surveyor's tape to measure the distance from the water surface tot he depth sensor on the instrument. (For the FSI MicroCTD-3, the calibration point is the end of the pressure sensor housing when the CTD is oriented with the pressure sensor housing held vertically upward.)Connect the instrument to a computer running a terminal emulation program, such as ProCom Plus for Windows, according to the instructions in the instrument manual, and initiate data acquisition at the highest rate available.

Record the pressure displayed on the PC screen.Retrieve the instrument from the water.Convert the absolute pressure to excess pressure by subtracting the atmospheric pressure (14.7 psi). Convert the excess pressure to the water depth by using the equation.Compare that depth with the chain/rope depth measured using the steel tape. The instrument depth should be within 0.2 m (0.6 ft) of the depth measured by steel tape.Pe D K UW 106 PSE&G Penmit Application 4t March 1099 Exhibit E-1 -3 Where: D = depth Pe =excess pressure (LB/in.2)UW = unit weight of water (lb/ft 3)K = conversion factor (144 in. /ft 2)107 PSE&G Permit Application

., M arch 1999 Exhibit E-1.3 APPENDIX E CALIBRATION/VALIDATION PROTOCOL FOR ACOUSTIC DOPPLER CURRENT PROFILER (ADCP)Velocity data in the Delaware River will be collected using a boat-mounted mobile Acoustic Doppler Current Profiler (ADCP), and a bottom-mounted, upward-facing, stationary ADCP. The instrument uses the shift in reflected sound frequency to measure the velocity indirectly.

By combining data from four sound beams and timing the echo delay, the ADCP is able to assign both speed and direction to layers of water at known distances from the instrument.

The ADCP can measure the velocity at varying depths over different spatial extents, the geometry of which is defined by the user. The ADCP is an inherently complex instrument which provides its user flexibility in both the type of data collected and the manner in which it is collected.

The mobile ADCP will be used to determine the variability of the velocity within a cross-section of the Delaware for each tidal phase studied. The bottom-mounted ADCP will provide variability of velocity with depth in the immediate vicinity of the discharge throughout the study period.The ADCP must first be configured for the specific environment and application for which it will be used. The Workhorse ADCP requires a maximum apparent velocity input, which corresponds to thexmaximum velocity the ADCP will measure (i.e., the vector sum of water velocity and boat speed). The value that should be used is 650 cm/sec, which is the maximum value the instrument is capable of measuring.

This value may be reduced to improve data accuracy, but at its maximum, an error on the order of 5 cm/sec may be expected, which is well within an acceptable range for the intended use of this information.

Previous surveys indicate that velocity varies significantly both temporally and spatially, and sacrificing some accuracy provides a greater assurance that usable data will be produced and that the operator will have greater flexibility in terms of boat speed and heading during data collection.

The configuration will be verified by technical support personnel from RDI (the ADCP manufacturer) and by preliminary testing under environmental conditions similar to those anticipated during data collection.

When the configuration of the instrument has been proven to be acceptable for the anticipated conditions, one ADCP will be deployed on the bottom of the river in the vicinity of the discharge, and the other ADCPs will be mounted on boats that will transect the river. The bottom ADCP will remain deployed for 12 days and will be configured to record data at three-foot intervals every 2.5 minutes. During the deployment, the bottom ADCP operation will be checked every 3 to 4 days. The boat-mounted ADCPs will collect data while an operator watches the data collection in real-time on a PC. Real-time display will be employed in which the magnitude, direction, and percent good velocitycan be viewed. If the magnitude of these values falls outside of anticipated ranges, the time and duration of these data would be noted so that these data can be disregarded in future analyses.108 PSE&G Permit ..\pplication 4 ,March 1999 Exhibit E-1-3 APPENDIX F CALIBRATION/VALIDATION PROTOCOL FOR ELECTRONIC ANALYTICAL BALANCES Two electronic scales will be used, one for each unit.

-4 March 1099 Exhibit E-1-3 APPENDIX G CALIBRATION/VALIDATION PROTOCOL FOR FLUOROMETERS Calibration will involve the addition of known increments of dye calibration solution (10 mg/I) to a known volume of Delaware water prior to the start of dye injection.

This water will be continuously circulated through the fluorometer and back into the container forthe remainder of the calibration.

Calibration solution will then be added from a 50-ml burette to raise the concentration of dye, by increments, in the circulating water. After each addition, when the water had reaches a well-mixed condition, temperature and fluorometer measurements at the appropriate fluorometer scales will be recorded every 2 to 3 sec for approximately 30 sec Temperature will be measured using the fast response Thermistor Temperature Modules.

Dye concentrations from 0.0 to 100.0 Ag/l will be used for calibration.

Calibration readings will be corrected to a reference temperature, using the following formula (Wilson 1968): Reading(RT)

= Reading(T)

(exp0026 * (T-RT))Where: Reading = fluorometer reading in volts T = ambient water temperature

(°C)RT = reference temperature

(°C)To account for the ambient fluorescence in the 100 1 sample of Delaware River water, the fluorescence reading prior to dye addition for each of the four fluorometer scales will be subtracted from the other readings at the corresponding scale. This will remove the background fluorescence of the calibration water from the data set. Corrected fluorometer readings will then be linearly regressed versus dye concentration to determine the intercept (A) and slope (B) for each fluorometer scale.

Background Fluorescence of the Study Area. To account for the background sources of fluorescence (e.g., phosphorescent algae), all measured fluorescence data will be corrected by subtracting the mean background value. Background measurements will be taken prior to the start of dye discharge.The mean background fluorescence will be subtracted from all the fluorescence data before they are converted to dye concentration values.Conversion of Fluorescence Values to Dye Concentration.

After the calibration regression coefficients (intercept

[A] and slope [B] for each fluorometer scale) are determined and the mean background fluorescence deducted, the following equation (Wilson 1968) will be used to calculate dye concentration (C) from the fluorometer reading and water temperature (T): 110 PSE&G Permit Apphcation 4 March 199)Q Exhibit E- 1-3 C = A + B

POSITIONING DATA All positioning will be accomplished using Differential Global Positioning System (DGPS) instruments.

DGPS instruments derive their primary positioning information from radio signals broadcast by a constellation of navigation satellites operated by the United States Department of Defense, known as the Global Positioning System (GPS).Typical radial accuracy of the raw GPS positioning data is about 200 m, but can be substantially better, depending on the current operational configuration of the system.Regardless of the GPS operational configuration, DGPS instruments correct the raw GPS positions to assure a radial accuracy of 3 m, by applying differential corrections broadcast from a local reference station. All DGPS instruments used on the survey will use corrections broadcast by the United States Coast Guard for the lower Delaware River.The current operational status of both the GPS satellites and the differential correction broadcasts will be monitored during the survey by accessing the US Coast Guard Navigation Center via the World Wide Web (http://www.navcen.uscg.mil).

This willassure that the DGPS instruments will be receiving correct data from the government-operated elements of the system. The survey will be delayed in the extremely unusualevent that the government-operated elements are not able to provide usable data during the survey.Thus, the only additional potential source of error is the DGPS instrument aboard each survey vessel. In the context of the survey, DGPS instrument accuracy is not a function of location, as long as a Coast Guard differential correction is available.

There will be five DGPS units in the field during the survey, so the best way to field validate the operation of these instruments is inter-comparison of the five units at a fixed location.

It would be extremely unlikely for more than one unit to fail under the survey conditions, so this type of inter-comparison can be expected to identify any such unit.Each unit will first be installed aboard its vessel in its final operating configuration, including the location of the GPS antenna' and any other electronics to be used aboard the vessel during the survey. When all five vessels have been fitted out with their full suite of instruments, each vessel will be positioned so that its antenna is adjacent to a fixedreference, such as a pier piling, that does not block the antenna's "view" of the sky. All instruments and computers aboard the vessel, including any navigational instruments 1 The fundamental position information reported by the DGPS unit is the position of the GPS antenna on the WGS-84 ellipsoid.

113 PSE&G Permit Application 4 March 1999 Exhibit E-1-3 normally found aboard the vessel, will be operating during the test. The position reported by each unit will be recorded and plotted. Each unit will be considered to be operating correctly if its position is within 3 m of each other unit's position.

Failure of any unit to achieve this criterion will be investigated and, if attributable to the unit, it will be replaced with a functioning unit.

If attributable to another cause, such as electronic interference, attempts will be made to resolve the problem. After resolution of any such DGPS failure, all five units will be re-tested as described above.TIME DATA Each data record logged by an on-board data computer or fixed instrument will be tagged with the time and date the data were acquired. The time/date used to tag the records will be the time/date of the clock in the computer or fixed instrument doing the logging.An accuracy of+/-l to 5 minutes would be more than sufficient for the ultimate use of the data in modeling and oceanographic analysis, but, to achieve correlation of data among the various instruments, a much higher level of accuracy is required.

All data logging computers and instruments will be synchronized to within Il second of the time signal available from the Global Positioning System. The GPS time signal is actually several orders of magnitude more accurate than is required for this survey, so it can be relied on as a time standard.

The synchronization accuracy is limited to +/-1 second by the resolution of the software used to set the computer clocks, which is typically 1 second.GPS units will be available throughout the survey period, so the time standard will alwaysbe available.

The fixed instruments will be synchronized to the GPS time when they are deployed and the action recorded in the instrument log. When the instruments are retrieved, the instrument clock will be compared with the GPS clock and the result recorded in the instrument log. This procedure will allow the time tags to be adjusted for any clock drift during the survey period.

The mobile data logging computers will be synchronized with the GPS time signal on adaily basis during the survey period. Before the clocks are synchronized, the clockreading will be compared with the GPS signal and the result recorded in the data log, to permit adjustment for any clock drift.114 Figure 10-1 PSE&G 2-Unit Intensive Survey Study Area~~~~~300000- , ., 29000& , ' , < J 28000& 4, 27000+6 Mi~/1~Salem River.+6,Mile/2600001 I 250000&.i

INTRODUCTION A bathymetric survey was conducted on 18 September 1998 in the vicinity of the discharge pipes for the Salem Generating Station Circulating Water System (CWS). The objectives of the survey were to (1) verify the location of the discharge pipes and their termination in a coordinate system compatible with the thermal plume modeling (described in Attachment E-2); and (2) map the fine-scale bathymetry surrounding theCWS discharge, which, based on the analysis of near-field temperature data and preliminary near-field computer modeling results, was believed to influence the near-field plume processes.

This survey was therefore conducted to support the near-field modeling, which required more detailed information regarding bathymetry in the vicinity of the discharge to provide an adequate understanding of near-field plume processes.

The survey found the midpoint of the discharge pipe array ends at Easting (X) =1,753,925 feet, and Northing (Y) = 229,615 feet, in the New Jersey State Plan North American Datum 1927 (NJSP-NAD27)

Coordinate System. This position corresponds to 828ft West and 1,115 ft South in the Station coordinate frame.II. CONSTRUCTION PLANS Construction plans of the cooling water discharge site were provided to the survey team to assist in designing the bathymetric survey. These plans were also used to interpret the survey data. According to PSE&G Drawing 211199-A-8855-5, the construction plan extended the pipes approximately 500 feet from the seawall. E- 1-4 Figures I1-1 and 11-2 provide summary information extracted from this drawing, the relevant details of which are reviewed below.E-1-4 Figure II-1 is a plan view of the pipe terninations and the surrounding area. E-l-4 Figure 11-2 is a corresponding side view. The discharge pipes extend approximately 505 feet (450 feet of which are buried) offshore from the property line. The end of the pipes is shown by the gray rectangle on E-l-4 Figure Il-1. The width of this multipipe discharge terminus is approximately 90 feet. A concrete apron the same width as thedischarge structure was placed at the terminus, extending 20 feet seaward of the terminus.Riprap surrounds the terminus, extending 120 feet seaward, approximately 63 feet shoreward (east) beneath the pipes, and nearly 125 feet to either side (north and south) of the diffuser's midpoint.

The riprap region is shaded gray on E-1-4 Figure I1-1. West ofthe riprap is a dredged section having a width (perpendicular to the discharge pipes) that ranges from 90 to 250 feet and an indeterminate length along the axis of the pipe that isgreater than 350 feet.3 0 PSE&G Permit Application 4 March 1999 Attachment E-L-4 I1. SURVEY INSTRUMENTATION The survey was performed on 18 September 1998 aboard the Northstar 4, a 50-foot work vessel well suited to this type of survey. The following instrumentation was used: aTrimble NT200 Differential Global Positioning System (DGPS), an Odom EchoTrac DF3200 echo sounder, an NEC P/75 75 MHz Pentium laptop computer (with Hypack software), and a Brancker TG-205 tide gauge.The echo sounder was calibrated prior to the survey to ensure it recorded accurate water depths. The method used to calibrate the echo sounder was the widely used bar check method, in which a bar is dropped to several measured depths and the echo sounder's measurements of the bar's depth are compared for accuracy. At all depths, the difference between the echo sounder output and the known depth was less than 0.1 feet, a high level of accuracy.Echo soundings are difficult to obtain within the immediate discharge mixing area of thethermal plume because of its extreme turbulence and density differentials.

Acoustic scattering in such strong flow can render an echo sounder useless. To maximize the ability of the echo sounder to read accurate water depths in the area, multiple passes weremade through the discharge plume prior to the survey to test various configurations.

These tests indicated that the best results were collected when the echo sounder was set todual frequency (24/200 kHz) with high output power and the gain tuned to about three-quarter scale. Gain is a setting that can be adjusted to reduce the level of noise in the echo sounder output. The high-frequency 200 kHz channel provided the best resolution of depth through the discharge plume. These settings also were used to improve upon a preliminary survey that was conducted in August 1998 (Woods Hole Group 1998).The laptop computer was configured to record both differential-corrected GPS positions from the Trimble DGPS, as well as digital echo soundings from the Odom EchoTrac DF3200. The Hypack software package integrates both signals and produces data files of position relative to depth and time.A Brancker TG-205 tide gauge installed on a pier piling in Sunken Ships Cove measured water elevation changes throughout the survey to a vertical resolution of approximatelyone centimeter; these data were used to correct the bathymetric readings for changes in tide level during the approximately three-hour survey. Water level readings, computed from a burst average of 32 instantaneous readings sampled at 2 Hz, were obtained every 5 minutes. The tide gauge's internal clock was synchronized to the survey clock to ensure a correspondence in times.The tide gauge was not surveyed to the Plant's established vertical datum; hence, water elevations are relative to the low tide of the day, not to an absolute datum. However, the vertical position of the tide gauge was measured relative to a known location on the pier, so future corrections to a known vertical datum could be made if required. (In this case, 4 PSE&G Permit Appiication

-4 March 1999 Attachment E- 1-4 because the data were not imported directly to a computer model, it was not necessary tohave the data referenced to an exact datum.)

IV. SURVEY PROCEDURES The survey area extended from the shoreline approximately 1,000 feet toward the center of the river, and spanned the shore region from the Station's circulating water intake basin to the Station's service water intake basin (approximately 750 feet). The discharge pipes were known to be located within this survey area from the construction drawings and previous surveys in this region (ACI 1994; Wood Hole Group 1998).The survey area was mapped using a grid of shore-parallel transect lines and shore-normal tie lines. The spacing between lines varied with distance from the discharge.

In the immediate vicinity of the discharge, the spacing between the shore-parallel transect lines was 20 feet, and the shore-normal tie line spacing was 25 feet. Farther from the discharge, the line spacing was doubled, and near the boundaries of the survey area farthest from the discharge, the line spacing was tripled. As a result, the bathymetric survey provides variable resolution in the horizontal plane, with the finest resolution (highest data density) in the immediate vicinity of the discharge.

It was extremely difficult to navigate the vessel through the turbulent area where the plume surfaces.

The discharge flow would push the vessel off its desired path and away from the discharge surfacing location.

As a result, transect lines show characteristic deflections in the immediate area of the plume. E-1-4 Figure VI-l illustrates the vessel's*track lines.V. DATA QUALITY CHECKING The raw data were quality checked. The quality check consisted of plotting each individual shore-parallel transect line and shore-normal tie line. Each line was studied closely to identify any "outlier" points, which commonly occur during bathymetry surveys and which represent unreasonable depths or positions.

Except in the highly turbulent discharge region, there were very few outlier depths that needed to be filtered from the data set (see discussion of post-processing below). Furthermore, the strength of the differential signal ensured that there were no data points lost due to an inability to correct using that signal.Although the bathymetry data collected were of high quality, there was a small area in the center of the discharge plume where no data were collected due to acoustic scatteringproblems and the aforementioned ship maneuverability problems, both of which were due to turbulence associated with the discharge plume; however, only a small portion of the near-field was not surveyed.VI. DATA POST-PROCESSING AND RESULTS VI.A. Data Post-Processing The post-processing consisted of three steps: First, the raw bathymetry data were tide-corrected using the tidal elevation data collected at Sunken Ships Cove. Outlier points Aa5 PSE&G Permit Application 4 March 1999 Attachment E- I.4--were then filtered from the corrected data set. Finally, adjacent raw data points were block-averaged by calculating one averaged data point along every five feet of a transect line.VI.B. Results The post-processed data are plotted in E-1-4 Figure VI-l. Each dot represents an individual data point and, in series, the data points depict the survey lines. The Easting and Northing locations are given in NJSP-NAD27 coordinates in feet. The color of each point indicates the measured value of water depth as shown on the legend.Based on the individual averaged data points, a Triangular Irregular Network (TIN) was created. The TIN joins the individual data points to form a continuous surface similar to a contour map as shown in E-l-4 Figure VI-2. The TIN highlights continuous features of the bottom such as ridges and troughs. E-1-4 Figure VI-2 shows the area of the bathymetry survey relative to the shoreline and the discharge pipes, as well as the limits of the bathymetry survey relative to where the discharge surfaces on a flood tide, as indicated by the closed black loop near the center of the plot. Differential GPS positions were recorded aboard a vessel that was navigated along the perimeter of the disturbed water surface, as determined visually during a flood tide on 20 August 1998. This plume surfacing location survey was conducted in conjunction with a preliminary bathymetric survey and a mooring turn-around mission conducted during that time.E-1-4 Figure VI-3 is a cross-section of the bottom in front of the discharge pipe. E-l-4 Figure VI-4 shows a close-up of the TIN model in the immediate vicinity of the discharge location.

The black curve again represents the perimeter of the disturbed surface water on 20 August 1998. The white dots represent the block-averaged data, and are provided to illustrate the density of data used to generate the TIN model.VII. DATA INTERPRETATION AND DISCUSSION VII.A. Discharge Location Interpretation of E-1-4 Figures VI-1, VI-2, VI-3, and VI-4 indicates the location of the discharge pipes as well as a variety of bottom features in the vicinity of the discharge.

The location of the discharge is apparent from the TIN descriptions of the bathymetrydata presented in E-1-4 Figures VI-2 and VI-4, and this TIN-based location is then overlaid on the bathymetry data.Comparison of the original construction plans to the bathymetric data collected in the Survey suggests that the pipes extend southwestward from the seawall between the service water intake and the Circulating Water Intake Structure (CWIS) for the Station.The pipes (represented by the long dark blue feature in E- 1-4 Figure VI-2) extend from north coast side of the survey rectangle toward the middle of the survey area A close-up of the survey region presented in E-1-4 Figure VI-A shows the point where the pipes are no longer covered by sediment (shading changes to light blue) and the point of termination of the pipes (light blue changes to yellow)..

Based on the data, the midpoint 6 PSE&G Permit AppIhc:0or 4 Ma1rsh 1999 Atlachm~n E- 1 -.4 of the multipipe diffuser is Easting (X) = 1,753,925 feet, Northing (Y) = 229,615 feet, in NJSP-NAD27 coordinates; or 828 feet West, 1115 feet South in Station coordinates.

The location of the midpoint of the discharge interpreted from the bathymetry data was.within 15 feet of the midpoint shown on the original construction drawings.

This close areement confirmed the accuracy of the bathymetry survey, and provided confidence in interpretation of other bottom features in the vicinity of the discharge.

VII.B. Bottom Features in the Vicinitv of the Discharge In addition to the location of the discharge pipes, E-1-4 Figures VI-1, VI-2., and VI-4 reveal features of the bottom in the vicinity of the discharge.

In E-1-4 Figure V1-4, the yellow band just seaward of the diffuser and between the light blue and orange regions indicates the 20-foot concrete apron. The orange section, where the plume surfaces,encompasses most of the area where no data were collected and is largely interpolated.

Based on the discharge configuration shown in E-1-4 Figures 11-1 and 11-2, it appears that the interpolated section lies within the riprap region surrounding the discharge.

The dark red sections represent a bottom depression seaward of the riprap, and correspond at least in part to the original dredged area. Seaward of this depression is a small rise in the bottom (shown in yellow) between the interpolated orange section and the deep red section.VIII. CONCLUSIONS The bathymetry data collected in the vicinity of the discharge show midpoints and bottom features consistent with the construction plans, features that were of significant interest with regard to understanding and modeling near-field plume dynamics.

The data show that the discharge pipes are buried by sediment for the majority of their length. They appear to emerge from the sediment approximately 50 feet from the discharge point. The discharge piping itself is fronted by a flat concrete apron,,which is shown in the original construction drawings.

Although the region immediately in front of the discharge was not well characterized by the survey, there is clearly a bottom depression extending for a distance of 50 to 100 feet in front of the discharge.

Based on the original construction drawings (E-1-4 Figures fl-1 and 11-2), it is likely that this bottom depression is a remnant of the initial dredging, that a portion of it closest to the discharge is armored with riprap,and that it is maintained in part by the discharge flow velocities.

The bottom features revealed by this survey significantly impact the evolution of the plume in the near-field, and are of particular relevance to the near-field computer modeling efforts. These bottom features tend to cause the plume to surface and mix throughout the water column relatively rapidly, as evidenced by field data and the simulations of the near-field model (see Section LII.B of Attachment E-2 for a detailed discussion of these processes).

The River and the marshes together comprise the Estuary environment.

The marshes are in part responsible for significant temperature variations in the River, and are important influences on the overall heat budget of Estuary waters. Any assessment of potential environmental impacts of the heat discharged into the Estuary from the Station's condensers must take into consideration these additional natural sources of thermal fluctuation.

1. INTRODUCTION Extensive salt marsh areas occupy the shores of the upper par. of Delaware Bay, including the area around Salem Station. For example, the Alloway Creek marsh complex, which is just north of Artificial Island and closest to the Station, covers approximately 10 square miles immediately around the Station (Appendix C Section VII.C). Hope Creek and Mad Horse Creek are located approximately three and eight miles south of the Station, respectively.

The marshes are shallow (typically only 1.5 to 2.0 feet (0.5 to 0.61 meters) deep in most places at high tide), and most of their surface area is exposed (uncovered by the water) when the tide falls below Mean Tide Level (Appendix C Section VII.C.5).

The marsh sediments are composed of dark, fine-grained, sandy mud and plant detritus (Appendix C Section VII.C.5.), but only part of this substrate is directly exposed to the sun and the air because the marshes are also coveredwith dense vegetation (Spartina alterniflora, Spartina patens, Distichilus spicata, Phragrnites australis), and related high- and low-marsh species. A network of relatively deep but narrow creeks drains the water out of each marsh on the falling tide and channels water into the marsh on the rising tide. The marshes are connected to the River through narrow inlets or creek mouths that penetrate the barrier beaches along the River's edge.The marshes cover a large area, even in comparison to the area of the River. Within a 20-mile length of the Estuary centered on the Station, the marshes and creeks cover an area of about 71 square miles (Table I-1). Thirteen separate marsh areas on the New Jersey shore and ten areas on the Delaware shore between RM 40 and 58 are identified in this table, which also gives the area of individual marshes and their tributary creeks (United States Fish and Wildlife Service 1981). The surface area of the River between about RM 40 and 60 is approximately 65 square miles (as computed from NOAA navigational chart# 12311), excluding the marshes, creeks, and other tributaries.

The marshes and their creeks thus cover a larger surface area than the River itself in this particular region.The marshes, like the River, are exposed to the sun and the air, and are rarely at thermal equilibrium; the water in them continually gains or loses heat through radiation, evaporation, conduction, and convection.

As a result of their large surface area and near-complete drainage into the River on every tidal cycle, they are potentially massive sources 4 PSE&G Permit Anplication 4 March 1t99 Exhibit E-1-5 or sinks for heat to and from the River; their shallow depth results in large changes in temperature from a given heat input. To better understand the Station's potential impact on an environment subject to this natural source of temperature variability, two primary questions are addressed in this Exhibit: 1. What volume of water at significantly elevated temperatures is contributed to the River by the marshes, and how does this volume compare in magnitude to the Station's thermal discharge?

2. Do the marshes contribute significantly to the dissipation of heat from the Station?II. HEAT EXCHANGE BETWEEN THE MARSHES AND THE RIVER II.A. Background The marshes contribute the greatest quantity of heat to the River following a high tide inthe early afternoon on a clear, warm day. Under these conditions, the water covering the marsh plain at high tide has the greatest opportunity to absorb heat from the sun and air.When the tide ebbs, water drains from the marsh and carries its heat load into the River as a nearshore thermal plume. A different situation occurs following a high tide on a cold night. In this instance the marsh water loses heat rapidly through back radiation and conductive/convective exchange with the atmosphere.

The marsh acts as a relative heat sink, releasing cold water into the river when the tide ebbs. The magnitude of heat exchange between the marshes and the River also varies seasonally, responding to changes in the incoming solar radiation (insolation), air-water temperature difference, and dew point.Heating or cooling of water in a marsh is complicated because it is not simply a water or mud surface. Over portions of vegetated marsh plain, sunlight first strikes the tall marsh grass that partially shades the actual water or mud surface. Some of the sunlight is reflected; the remainder heats the leaves of the grass and, ultimately, the surrounding air.The marsh grass acts as an insulator, trapping the heat of the sun in the air, which then transfers heat to the water conductively.

The growth stage of the grass influences its effectiveness as an insulator.

Even at low tide, when water is not present, heat is exchanged between the sun, the air, and the mud. This heat surplus or deficit (cold) is transferred to the water when it returns on the flood tide, so the marsh acts like a heat reservoir.

At the latitude of Delaware Bay (390 to 40'N), the sun's radiation has an effective heating power at the top of the atmosphere of about 765 watt/in 2 at the summer solstice (21 June)when the sun is closest to directly overhead (Linsley et al. 1949). However, the sun is not always directly overhead, and not all of the sun's heat reaches the marsh water. For a preliminary estimate of marsh heat transfer, the effective solar heat input to the water in summer (averaged over about eight hours around midday) is assumed to be 150 to 500 watt/m 2 , with the lower value corresponding to a cloudy day.5 PSE&G P,,mn .-\pplicauon 4 March i999 Exhibit E-I-5 II.B. Marsh Heating Rate.and Temperature Response To approximate the heat transfer from marsh to River during the course of a single day, it is reasonable to focus on the effect of incoming solar radiation, which is ultimately the driving force for temperature changes, while neglecting air-sea heat exchange due to otherfactors. The marshes, like the River surface, gain and lose net heat as a result of various air-sea heat flux mechanisms, including incoming long-wave sky radiation, back radiation, evaporative heat loss, and conductive heat loss or gain. However, the air-sea heat fluxes associated with these other mechanisms typically do not vary as rapidly as the short-wave heat input due to the sun, which ranges from zero at night to a maximum at midday. Evaporative and conductive heat exchanges are dependent on the air-sea temperature difference, which usually increases each day in response to solar heat input.Neglecting these mechanisms terms is therefore a conservative approach, all else being equal. Radiative mechanisms depend on absolute temperatures, so their heat flux varies slowly over the time scales corresponding to the passage of major weather systems, whichcan cause systematic changes in bulk water and air temperatures.

To evaluate the importance of marsh heat transfer, the probable range of heat transfer rates, temperature changes, and outflow volumes were calculated.

On an overcast summer day, neglecting other mechanisms of heat exchange, incoming solar radiation at 150 watt/m adds heat at a rate of about 390 MW/mi 2.A ten-square mile marsh, similar to the Alloway Creek marsh, would have an effective 8-hour average heating rate of 3,900 MW on a cloudy day. Whether wet or dry, the marsh absorbs the sun's heat during all the hours that sunlight falls on it. This heat is then absorbed by the water during flood tide, and transferred into the River during the ebb phase. Over the course of eight hours of sunshine, a total of 31,200 MW-hrs. of heat energy would be added to the water in this marsh. This heat would then be advected into the River during the ebb phase, which typically lasts six hours. Therefore, the rate at which heat would be added to the River during a 6-hour ebb phase would be 5200 MW. The effective heat transfer rate to theriver could be lower or higher depending on the relative phasing of the tide and the sun, and on the speed of marsh drainage.

For example, if the marsh drains completely in only five hours, then the heat rate for the River during the ebb flow period would be 6240 MW, a rate comparable to the combined heat rejection rate of both Units of the Station through the condensers (6,000 MW; Appendix B) in the form of the Station's thermal plume. Averaged over the entire solar day, the heat input due to insolation of this marsh would come to approximately 31,000 MW-hrs. per day.Even the minimal amount of insolation corresponding to a cloudy day can raise the temperature of the water significantly.

Applying 150 watt/m2 to water about 2 feet (0.61 meters) deep on average during.the 6-hour flood period will result in a AT of about 1.2°C (2.1 °F) in the water later discharged from the marsh. This does not account for heat transferred from the mud (which can be heated while dry) to the water, which can raise the temperature even more.

This temperature increase is comparable to or greater than the 1.5°F AT value used to define the maximum extent of the Station's plume.6 PSE&G Permit

\nikcatorn 4 March .,n 00 Exhibit E-I-5 On a sunny summer day, when 500 watt/mr 2 of solar insolation may be applied to the marsh, the heat rate can be about 1300 MW/mi', (13,000 MW for the 10 square miles of Alloway Creek marsh) and the temperature rise about 3.9°C (7.0°F), (again, neglecting any other variations in air-sea heat exchange).

This quantity of heat is greater than that discharged by the Station, and the AT of the marsh discharge is larger than the AT of all but a small part of the Station's thermal plume.The open water surface of the River also gains and loses heat due to the same mechanisms that operate in the marshes. However, the input of an equivalent amount ofheat directly to the River surface will not produce the same temperature increase as it would in the marshes. In the River, the water is much deeper, and mixing due to tidal currents, winds, and waves distributes the heat rapidly through the water column.Presumably, insolation would tend to produce a warm surface layer during slack water periods, but their duration is brief, typically less than an hour, so this layer never builds up.II.C. Comparison of Temperature Volumes The volume of water associated with marsh outflows is also comparable to the volume of the Station's thermal plume even at high dilutions.

Volume outflow of the marshes can be approximated as the product of the surface area and the average depth of water during the flood half-cycle, because all this water drains out on the ebb tide; this volume is independent of the amount of heat added to or removed from the water. Assuming a 2-foot (0.61 meter) average depth, a single square mile of marsh will drain 1,280 acre-feet of water. A ten-square mile marsh such as Alloway Creek will introduce nearly 13,000 acre-feet of water into the River on each falling tide. If the marsh temperature increase is 2°C (3°F)-which is a common occurrence-the volume of water at that temperature injected into the River from Alloway Creek marsh will be comparable to the volume enclosed by the same 3°F AT due to the Station's discharge.

Table II-1 gives cumulative estimates of volume of various AT isopleths of the Station's plume, as predicted by the CORMIX and RMA-10 models (Appendix E Section V.F). The volume enclosed by the 3°F AT isopleth, for example, is in the range of 12,000 to 14,000 acre-feet matching that of the ten-square mile marsh.Extrapolating to a wider area, the 73 square miles of marsh in the 20 mile reach of the Estuary around the Station contribute more than 100,000 acre-feet of water to the Riveron each falling tide.

Therefore, the total volume of heated water entering the River from the marshes with a temperature increase of 3°F can be as much as seven times larger than the volume of the Station's plume within its comparable 3°F AT isopleth.Cross-channel exchange in the main stem of the River is weak compared to along-channel advection and mixing (Appendix C), so water that flows out of the marshes tends to remain close to the shore near its origin, where it is advected along-shore by the tide and mixed slowly toward the center of the River. The typical along-shore tidal excursion is three to six miles (five to ten km) (Appendix C), comparable to the distance between marsh outlets. Thus the marsh thermal plumes tend to merge into a more-or-less 7

PSE&G Per'mi[

4 March 1)IN Exhbit E-continuous band of elevated temperatures along the River'.s edge. Although some dilution occurs as the marsh outflow mixes with the ambient River water, the result is a large area -- thousands of feet wide and many miles long -- over which the excess temperature due to marsh heat exchange is comparable to the Station's thermal plume within the 1.57F AT isopleth.l.D. Probability of Occurrence of High Heat Exchange High levels of solar heating and advective transfer from the marshes do not occur all the time, but only when the right combination of insolation, air temperature, and tidal phasing occurs simultaneously.

However, such conditions are frequent.

In particular, favorable timing of the tide in relation to insolation must be present during about half of each lunar month. For example, when the tide is high in the afternoon, timing is optimal for heat transfer.

The semi-diurnal tide has a period of 12.42 hours4.861111e-4 days 0.0117 hours 6.944444e-5 weeks 1.5981e-5 months , so the timing of flood and ebb tide slips relative to the sun by 50.4 minutes each day. After about seven or eight days, the tide will be low in the afternoon, which is not an optimum condition for marsh discharge at high AT. After another seven or eight days, the phasing will be favorable again; thus there is a 14.8 day periodicity in the occurrence of most favorable conditions.

This periodicity is observed at the marsh outlets. For example, Figure I1-I shows the time history of temperature observed over a 3-month period at Salem River during June-September 1998. Diurnal temperature fluctuations of up to 3YC (5.4°F), associated with daily heating and outflow from this marsh, are evident in this time history. These daily temperature fluctuations occurred most of the time, superimposed on larger and slower temperature changes associated with synoptic and seasonal weather patterns.

The diurnal temperature increases were greatest when the high tide occurred in the afternoon, as it did around 21 July 1998. Similar fluctuations were also observed about two weeks later, when the tide was again high in the middle of the day.Cloudiness and cold air temperatures, which reduce solar and atmospheric heat input, have no consistent relationship with tidal phase.

Insolation is highest in early summer, but cloud cover tends to be minimal in early fall. Table H-2 gives monthly sky cover statistics for Wilmington, Delaware.

On average, the least cloudy conditions occur in October. It must be noted that partial cloudiness, as defined in this table, does not imply a total obstruction of solar heating.

Taking into account solar and meteorological factors and tide phasing, a conservative estimate is that conditions favorable for net heating of the marshes occur between 30 percent to 50 percent of the time in the summer.II.E. Marshes as Cooling Surface for the Station's Thermal Discharge Cooling of water in the marshes can also be a factor in dissipating the heat produced by the Station. If the Station's diluted thermal plume enters a marsh on a rising tide, thesurface area available for heat exchange with the atmosphere is increased as the plume spreads over the shallow water of the marsh. This cooling effect is limited to marshes near the Station.If the Station's plume enters the marshes at all, it does so in a highly diluted state, with low AT, and cannot be distinguished observationally against natural background 8 0 PSE&G Pe,"rnm, Application

-4 March 1999 Exhibit E-1-5 temperature variability.

Therefore, model predictions must be used to investigate the importance of the marshes for cooling the plume. Figures 11-2 and 11-3 show temperature Fields from a calibration run of the RMA-10 model at peak flood and ebb excursion, respectively (Appendix E Section V.E.). The marshes are represented as broad, shallow embayments of uniform depth, rather than as actual complicated marsh plains and tributary creeks. In these figures, the approximate boundary of the River, including its idealized marshes, is superimposed on the model domain.These model simulations reveal that interaction between the plume and the marsh occurs most often at Hope Creek, but that the immediate plume from the Station does not flow directly into this marsh. Instead, a portion of the plume with low AT that occupies the embayment south of Artificial Island at the end of the ebb phase is swept into Hope Creek with the flood tide. By the end of the flood phase, a portion of the former ebb plume has entered the marsh, where its heat continues to dissipate.

At that time, the portion of the plume area inside the Hope Creek marsh is estimated to be approximately 30 percent ofthe total 1.5'F plume area. Table 11-3 shows the surface area of the Station's plume as estimated by the CORMIX and RMA-10 model (Appendix E Section V.F.). The maximum area of the 1.5°F isopleth of the plume during flood tide is about 3,200 acres, or about five square miles. Thus nearly the entire

1.5 square

mile area of Hope Creek marsh is actively involved in cooling the Station's plume, although the water that enters the marsh is already diluted to a low temperature.The model predicts that relatively little of the Station's plume enters Alloway Creek. At the start of the flood phase, nearly all of the residual plume from the previous flood phase has been swept away, so the water north of the outfall is near ambient temperature.

As the flood tide progresses, the ambient water fills Alloway Creek marsh. By the time theimmediate plume reaches its entrance several miles north of the Station, the marsh is already nearly filled to capacity and little of the plume water enters. The plume fills the embayment in front of the marsh entrance instead.At the end of the ebb phase (Figure [1-3) all the water has drained from the marshes.However, heat transfer still continues as the mud and vegetation in the marsh exchanges heat with the air.III. OBSERVATIONAL EVIDENCE FOR MARSH HEAT EXCHANGE III.A. Previous Study of Marsh Heat Exchange Near Salem Generating Station A study of heat flux through Alloway, Hope, and Mad Horse Creeks (Weston Environmental Consultants 1978) confirms the concept of significant heat exchange, comparable to the heat output and temperature rise caused by the Station's thermaldischarge. Using an anchored boat, currents were measured at each marsh creek inlet at all four stages of the tide during a period when the ebb phase occurred in the afternoon.

-Temperature, salinity, and tide height were also measured, and the cross-sectional area ofthe creek mouths was mapped. Net heat flux was estimated by multiplying the best estimate of volume flux during a tidal half-cycle by the difference between flood and ebbflow-weighted mean temperatures.

For the conditions prevailing at the time (27 October 9 PSE&G Permit Appicauon 4 March 1990)E'hvbit E-1-5 1977, a heavily overcast day), net heat flux to the River resulting from the afternoon ebb flow was estimated to be l0.9x 10'2 g-cal from the three marshes together (Table 111-1;Weston Environmental Consultants 1978). This translates into a daily export of 12,670 MW-hrs, or an average of 2,100 MW over the six-hour heating half-cycle.

The average water temperature increase due to solar heating in the marsh ranged from 0.5 0C (0.9 0 F) at Mad Horse Creek to 0.80 0 C (1.4"F) at Alloway Creek, on this cloudy day.On the day of the survey, the average insolation was measured as 89 g-cal/cm 2 integrated over six hours, corresponding to an average solar heating rate of 172 watts/m 2.A clear October day at this latitude would have had an average daytime solar insolation rate of 350 g-cal/cm 2 (675 watt/m-) and the long-term average for the month of October (Weston Environmental Consultants 1978) is given as 278 g-cal/cm 2 (535 watt/m 2) at Seabrook, NJ, 27 kilometers east of Salem. If the 350 g-cal/cm 2 value had prevailed, as often would be the case in the summer, the heat input to the River from these three marshes would have been about 8,250 MW during the falling tide phase, and the resulting temperature increase would have been 1.9 to 3.10C (3.40 to 5.6 0 F). This range of temperature increase is consistent with observations at the creek mouths during the recent 1998 Modified Thermal Monitoring Program studies (Exhibit E-1-3), and with the calculated values discussed in the previous section (Section II).III.B. New Observational Evidence for Marsh Heat Exchange The exchange of large amounts of heat between the River and the marshes can contributeto large temperature fluctuations in the River around the Station. An observational component was therefore added to the 1998 Modified Thermal Monitoring Program (Appendix E Section V.D.; and Exhibit E-l-3), to measure the volume and temperature ofthe flow into and out of salt marshes near the Station. During the Two-Unit Survey, May-June 1998, temperatures and salinities were measured in the mouths of Alloway, Hope,and Mad Horse creeks, as well as at locations in the River, using moored instruments (Figure 111-1). The cross-sectional areas of the creek mouths were measured using a fathometer, and tide height was estimated from nearby fixed instrument measurements.

Intensive survey measurements of flow through the creek mouths were made on the four stages of the tide using a vessel-mounted Acoustic Doppler Current Profiler (ADCP).The moored instrument measurements in the creek mouths and at some of the moored instrument locations were extended until November as part of the 6-month Long-Term Survey (Exhibit E- 1-3).III.B.1. Evidence for Heat Outflow from Salem River Marshes Unambiguous evidence for temperature fluctuations of marsh origin in the River itself was recorded by moored instruments located nine miles north of the Station. Figure 111-2 shows temperatures measured at moorings 9G (on the west side of the River, near the Delaware shore) and at 9R (on the east side of the River, near Salem Cove), and the difference between these observations.

Also shown is tide height at Reedy Island, current direction at the ADCP near the Station, and solar insolation and air temperature measured at the Station.10 PSE&G Pormit Applcazion

-. March 1999 Exhbit E-I-5 Marsh outflow is not observed at mooring 9G on the west side of the River, where a pattern of regular semi-diurnal temperature fluctuations (1.8°F (I°C) peak-to-peak) occurs due to tidal advection of the mean longitudinal temperature gradient.

In contrast, mooring 9R on the east side of the River shows large temperature fluctuations of diurnal periodicity superimposed on top of the smaller semi-diurnal variations.

Mooring 9R is located about 1,000 meters (3,000 feet) offshore in the shallow, broad embayment of Salem Cove, directly offshore of a major marsh area and slightly upstream of the Salem River mouth. In addition to the Salem River itself, which drains much of the marsh region, there are several other creeks, such as Mill Creek, that drain into the River around this location.

The diurnal signal occurs at all depths and is strongest when the ebb flow occurs in late afternoon or early evening on days when insolation is strong and air temperature is high. For example, during the period 25-30 May 1998, temperature pulses of about 2.50 to 3.5°C (4.50 to 6.3°F) occur late in the day (around 1800 hrs), with maxima occurring shortly after the end of the ebb phase in the River.As there are no marshes on the west side of the River at this location, and no evidence of diurnal temperature fluctuations at the western mooring 9G, the warm pulses observed at mooring 9R must have come from a source on the New Jersey shore. This mooring is well beyond the farthest upstream extent of the Station's thermal plume (Section II). The occurrence of this temperature peak at the end of the ebb phase suggests that this fluctuation is not caused by the Station, and that it is indeed caused by the heated marsh outflow at this location.

The fact that marsh-generated excess temperatures are seen at all depths at mooring 9R, and at a distance of 3,000 feet offshore, suggests that the volume of the marsh outflow is substantial.

In early June, when the tide phase shifts relative to the solar day so that ebb tide is no longer in the afternoon, there is practically no diurnal temperature signal. The observations at mooring 9R are consistent with the previously described calculations of heat exchange and temperature response.Further evidence that the plume from the Salem River Marsh covers a wide area is found in satellite imagery. Figure 111-3 is a temperature map derived from satellite infrared imagery showing the Estuary around Salem (Offshore Services 1993), collected at 4:12 p.m. on 21 July 1990. Despite the poor spatial resolution of the satellite image upon which this contour map is based, a heated plume from the Salem River marsh is evident, with temperatures which differ from the ambient river temperature field by more than 3°F. This image also shows the Station's thermal plume. The surface area coveredby the marsh plume is much greater than that covered by the Station's plume, and the temperature of the marsh outflow is higher than all but a small part of the Station's plume.III.B.2. Evidence for Heat Outflow from Marshes Near the Station At Alloway, Hope, and Mad Horse Creeks, observed water temperatures (Figures 1I1-4, 111-5, and 111-6) show a strongly diurnal pattern (one high temperature per day) when the insolation is high and the ebb tide occurs in the afternoon or evening. This pattern is generally seen during half of each lunar month. Also shown on these figures are tide height and current direction measured at the bottom-mounted ADCP mooring V offshore 11 PSE&G Permit Appicatmn 4 March 0QQ9 Exhibi E-I-5 of the Station, as well as insolation and air temperature.

On cloudy days (low insolation) or days when the ebb tide occurred during the morning, the temperature fluctuations become smaller, more erratic, and more semi-diurnal in character, corresponding to lower heat exchange with the atmosphere and a more clearly defined tidal advective transport.

Although the temperature fluctuations seen at these marsh mouths are not as dramatic as those from the Salem River, there is no doubt that the marshes contribute significant volumes of heated water to the River.IV. CONCLUSIONS In summary, evaluations of the physical properties of the marshes, as well as historical and recent observations, demonstrate the following:

Due to their large surface area (comparable to that of the River), the marshes can store large amounts of heat and later transfer it to the River, with heat transfer rates from a single marsh being comparable to the Station's heat rejection rate (6,000 MW) on a cloudy day, and two to three times greater on a sunny summer day." Due to the shallowness of the water, the temperature increase resulting from solar heating in the marshes frequently exceeds 3PC (5.4°F) in the marsh outlets at ebb tide." The volume of heated water outflow from nearby marshes at these typical AT values is comparable to the volume of the Station's discharge at the same AT. For example, temperature increases of up to 3.5°C (6.37F) unrelated to the thermal discharge from the Station are observed north of the Station (near Salem River), and this warm water extends more than 3,000 feet offshore.

Somewhat smaller temperature increases are observed at other nearby marshes.* Conditions that commonly produce high temperature increases and high heat transfer from the marshes (sunshine, warm air temperatures, and high tide in the afternoon) occur on at least 25 percent of the days in summer, as confirmed by observation." Nearby marshes, especially Hope Creek, contribute to the cooling of the Station's thermal plume. The model shows that this marsh comprises approximately 30 percent of the total modeled surface area of the plume within the 1.5°F isopleth.Thus, the marshes help to dissipate a portion of the Station's heat load to the Estuary which would otherwise remain in the River.That the heat contributed to the River by marshes exceeds that contributed by the Station and that the marshes play an important role in Estuary-wide heat flux budgets are not new findings (Weston Environmental Consultants 1978). However, there are important implications of these observations:

1. Natural variability of temperature within the River near the Station is high due to marsh inflows. Diurnal variability can exceed 7°F when the ebb tide occurs during the late afternoon of a sunny day. In the absence of these marshes, the natural diurnal temperature variability in the River would be significantly lower.2. Organisms occupying this stretch of the River are exposed to these significant and widespread temperature fluctuations on a daily basis.12 PSE&G Permit Appicanon 4 March t099 Exhibit E-1-5 3. Field measurements cannot distinguish between marsh heat build-up and Station heat build-up at any AT except those exceeding the maximum marsh temperature.

Therefore, field measurements of temperatures within the Station's thermal plume must be interpreted with care, 4. Assessments of the potential environmental impacts of the Station's thermal plume must take into consideration the large natural variability caused by these numerous natural thermal discharges.

The contributions of the marshes surrounding the Station to daily temperature variations in the River are significant.

5. Numerical simulations of the heat in the River near the Station should consider the effect of this heat source.

At a minimum, the surface area of the marshes should be modeled to simulate their contributions to the River heat budget.13 PSE&G Permit Application 4 March 1999 Exhibit APPENDIX E EXHIBIT E-1-5 HEAT FLUX FROM THE MARSHES REFERENCES Linsley, R.K., Jr., M.A. Kohler, and J.L.H.
