I I EREEAC.E The Annual Environmental Operating Report (AEOR) presents i the information and data obtained from the implementation of Grand Gulf Nuclear Station's (GGNS) Environmental Protection
for the period January 1 through December 31, 1990. Historical information has also been included, where applicable, for comparison purposes.
The GGMS EPP requires monitoring for potential erosion along transmission line corridors and impact of cooling tower drift on vegetation. These are the only terrestrial issues required to be addressed by the GCNS EPP.
No aquatic issues were identified in the GGNS Final Environmental Statement. Consequently, none are addressed by the GGNS EPP. Effluent limitations and monitoring requirements for aquatic matters are contained in the GGNS National l
Pollutant Discharge Elimination System Permit issued by the Mississippi Departmont of Environmental Quality (MDEQ). Tho MDEQ requiates matters involving water quality and aquatic biota.
In addition to the required terrestrial issues, the AEOR also addresses environmental issues which are not within the l scope of the EPP. This provides a more comprehensive report for the Environmental Surveillance Program and informs the Nuclear Regulatory Gommission of environmental activities at GGNS.

INTRODUCTION Effective June 6, 1990, the Securities and Exchange Commission approved the consolidation of all Entergy Corporation nuclear operating and management functions into a new nuclear service company subsidiary, Entergy Operations, Inc. Entergy Operations acts as agent for the nuclear plant owners under separate operating agreements with each plant owner. One of these operating agreements is between Entergy Oparn. 'as and System Energy Resources, Inc. This agreement 0.. aster ed the managerent and operating responsibility of the G1and Gt.2 Nuclear-Station to Entergy Operations as agent for Systen. Ennegy. System Energy holds a ninety percent (90%) undivided ownership and/or leasehold interest in Grand Gulf, and South Mississippi Electric Power Association holds a ten percent (10%) undivided interest in Grand Gulf.
Grand Gulf Nuc3 ear Station consists of one operating boiling water reactor with a current not maximum dependable capacity rating of 1142 MWe, A second unit, on which construction had been previously_ suspended, was cancelled during September, 1989.
An application for termination of the construction permit was submitted to the Nuclear Regulatory Commission on December 27, 1990.
1.1 IMPACT ASSESSMENT AND
SUMMARY
Environmental Surveillance Program (ESP) personnel monitored the environmental impact of GGNS operational activities between January 1 and December 31, 1990. The monitoring results of the ESP contained in the following I l

-- .J
l i
sections indicate the environment was not adversely impacted in 1990 by the operation of GGNS. Environmental Surveillance Program personnel-have not observed any harmful effects or evidence of trends toward irreversible damage to the surrounding environment at GGNS.
The only unusual environmental events occurring in-1990-were fish kills near the discharge point of Outfall 001 and onsite Sediment Basin A in August and October,'respectively.
The fish kills were natural occurrences caused by dissolved oxygen depletion and-not related to station operation.
Acute effocLs were confined to the general; area and no chronic effects have been observed.
i overal1, surveillance-results for-1990 were-comparable to those of previous years. Results' remained within anticipated ranges and no adverse environmental impact was observed by ESP personnel.
1.2 GGNS SITE CHARACTERISTICS Grand Gulf Nuclear Station is locatad in Claiborne ,
County, Mississippi, on:the east _ bank of the Mississippi River, approximately 25 miles south of Vicksburg and 37 miles north-northeast of Natchez. Grand Gulf Military Park borders a portion of the north side of;the property, and the small community of Grand Gulf is_approximately one and one-half miles to the north. The_ town of Port'Gibson is about six miles southeast of the site. Two lakes,_ Gin Lake and Hamilton Lake, are located in the western portion of the q site. These lakes were once the channel of the Mississippi River and average about eight to ten. feet in depth. An area RPT7224/SRESFLR -:1-2

Figure 1-1. ,
! Site and-Its Environs-
-The site and its er4virons consist primarily of woodlands divided between two physiographic regions. -The-western half of the site is in the alluvial plain of the Mississippi River; the eastern half is in the Loess or-Bluff Hills. The elevation of the site varies between 60 and 80 feet above Mean Sea Level (MSL) in the alluvial plain r.egion, while the Loess Hills portion varies from=80 to more ,
than 200 feet above MSL.
Based on the GGNS Updated-Final Safety Analysis-Report,
-the current acreage figure for the site is approximately-2100 acres.
The site boundary is the same as the property line except in the southwest and west-southwest sectors as shown in Figure 1-2. A 2-acre residential property:within'the ,
southwest-sector is privately owned.
There are-no industrial, commercial, institutional or residential structures within the-site boundary. No railroads or navigable waterways traverse the site. Bald 1 Hill Road, formerly Waterloo Road, runs through.the GGNS site property. Bald Hill Road cuts through the-south-southeast, south, south-southwest, and southwest sectors of the site. Hamilton Lake Road, formerly a county RPT7224/SRESFLR 3

2.1 SMOKE CONTROL The GGNS Burn Pit, which was officially closed on February 22, 1990, was_ filled with dirt during the week of June 11, 1990, thus prohibiting any future use.
2.2 EROSION CONTROL ,
' Erosion control at GGNS is a priority because of the
' proximity of GGNS to the Mississippi River, the hilly terrain, the average annual rainfall of approximately 50 inches and the ;.oess soils which'are extremely susceptible to erosion. The methods which hgve been successfully utilized to control erosion ares o Revegetation of disturbed areas o Utilization of concrete chutes and flumes which ct'nnel runoff into two sediment basins, A and B (Figure 2-1).
Sedimentation occurs in the basins, which helps to minimize the ecological effect on Hamilton Lake and the-Mississippi River. <
As a result of Amendment 7 to GGNS Construction Permit Numbers CPPR-118 and 119, dated. December. 23,_1981, monitoring and capacity requirements for the sedimentation basins were transferred to the GGNS: NPDES Permit.
Runoff sample collection, which was-required prior to.
amending the Construction Permits, was discontinued on January 31, 1985. Monitoring of sedimentation-basins since 1
RPT7224/SRESFLR 1
January 31, 1985 has been conducted according to the parameters established by the GGliS NPDES Permit.
2.3 TRANSMISSION LINE SURVEYS The aerial surveys in previous years-have confirmed that soil and vegetation have stabilized along the GGNS transmission lines. Therefore, as permitted by Section 4.2.1, Paragraph 2, of the EPP, the Erosion Control Inspection Program was discontinued in 1988. +
2.4 LIQUID AND SOLID WASTE MANAGEMENT Liquid wastes, such as chemicals, fuels'and lubricants .
which could not be discharged as wastewater, were deposited or discharged into tanks and/or containers. These materials, excluding borated water, were salvaged or removed to appropriate offsite treatment and/or disposal
! facilities. Borated water was placed in the~onsite resin pond and in the treated. low volume wastewater pond. Care was taken to avoid the handling or storing-of liquids ~in
-close proximity of major drainage areas to avoid potentially damaging spills to site streams.
Construction scrap and debris were collected in designated onsite areas for salvage or burial.
Noncombustible solid wastes were buried-in designated landfill areas. ,

A contractor began collection and disposal of Unit 1 and Energy Service Center waste in-1988.. Prior to this arrangement, Unit 2 construction personnel-disposed of this
-waste onsite, 2.5 LAND MANAGEMENT AND WILDLIEE _,
Approximately 2100 acres make up-the GGNS site; 94 acres are fenced in the immediate plant area, with an additional 37 acres set aside for permanent-structures. -The remaining acreage provides excellent habitat for Mississippi- q wildlife.
Fringe areas and open fields were.normally mowed two times during each growing' season to keep open areas from being overtaken by scrub vegetation. After the growing season, a series of'small food plots were planted _in these open fields to help sustain wildlife populations through1the winter and early spring. A small fruit. orchard and two gardens were also maintained-on-site'by-= ESP: personnel.-
Two lakes locatedf onJ the site, Gin and: Hamilton, were -
used for sport and commercial fishing by area residents ~.
Use of the lakes and surrounding-local 11 ands by water' _
- dependent species (waterfowl) was-seasonal,ywith most activity occurring.during fall:and winter migrations.
Huntirg- on site was limited to bow hunting for in-season animals,-pursuant to.the: requirements of .j Mississippi hunting laws. Other-hunting activities were prohibited on thefGGNS site.

2.6 GROUNDWATER MONITORING.
The groundwater monitoring program'was continued-during. .
1990 at GGNS to: >
o Provide data on the seasonal fluctuation of the regional groundwater table ,
o Monitor the level of--the perched'oroundwater table around the Power Block areas.
Location of Monitorina Wells ;
Twenty-seven wells were used to monitor the regional and perched groundwater underlying GGNS:
o Twelve wells for regional groundwater levels in the-site area ,
o- Fifteen wells.for perched groundwater levels around the Power Block areas, i
Locations of monitoring' wells are shown in Figures 2-2 l l
and 2-3 and listed ~in Tables 2-1 and 2-2. t r
Recional Groundwater ;
Wells used to monitor the regional groundwater levels.
-(Figure 2-2 and Table 2-1)-were normally' measured at least-l twice a month. !
1 Perched Groundwater :
s GGNS has a monitoring and dewatering system-(Figure 2-3 j
and' Table 2-2)-located around thel Power Block and the
- Standby Service Water Basins to monitor and dewater.the ;
underlying-perched aquifer. Seven monitoringfwells (MW-1 through-MW-7) were used:to monitor the water levels in the perched' aquifer. Eight. dewatering wells (DW-1 through DW-8), _
I

2.7 NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES)
PERMIT ,
1 National Pollutant Discharge Elimination System (NPDES)
Permit No, MS0029521 was amended and reissued to GGNS on October 9, 1990. The permit as issued in October 1990 consisted of 13 outfalls.
The permit allows GGNS to discharge wastewater, in accordance with NPDES regulations, into Hamilton Lake and the Mississippi River. NPDES reporting requirements are established by the State of Mississippi. Monthly Discharge Monitoring Reports (DMRs) for each outfall were prepared and sent to the Mississippi Department of Environmental Quality and the U. S. Nuclear Regulatory Commission via NPDES Monthly Reports.
- 2.8 THERMAL MONITORING PROGRAM l Grand Gulf Nuclear Station's NPDES Permit requires that l
GGNS effluents and the Mississippi River mixing area be monitored to determine what effects, if any, will result from GGNS's heated discharge into the. river. The NPDES Permit states:
The receiving water shall not exceed a maximum water temperature change of 2.8 C (5.0 F) relative to the upriver temperature, outside a mixing zone not exceeding a maximum width of 60 feet from the river edge and a maximum length of 6000 feet downstream from the point of discharge, .
as measured at a depth of 5 feet. The maximum l RPT7224/SRESFLR 5
water temperature-shall-not_ exceed 32.2 C_-(90 F)'
outside the same mixing zone, except when ambient temperatures approach or exceed this value.
f Prior to issuance of the amended October 1990 NPDES Permit, monitoring was conducted' semiannually (once in winter and once in' summer) when Unit 1 was operating at a minimum of ,
25% power.
The amended permit as issued in October 1990, only requires monitoring when the river stage.is.less than 15.4 feet during winter months-(November-April) or, is less than minus 1.2 feet during summer months (Mayz -
. October). In addition, once monitoring has been performed at river stages less than.the 15.4 and minus 1,2 feet limits, the river stage which existed at the time of monitoring will become the new limit.
l To initiate the thermal monitoring protram and ob'tain baseline data, the river bank-was surveyed to establish and permanently-mark 72 reference points 100 feet apart. ,
I Sixty-six of the reference-points'were located _ downstream of GGNS's discharge into the river, and the-remaining six'were
-located upstream-of the discharge.
1 Calibrated digital thermometers.were used toLobtain-temperatures at.a depth of five feet and at the surface. At each selected reference point, measurements were.taken i 100 feet from the river bank, then at 10 foot intervals _until reaching the bank.-- This provided 20 temperature data points for each reference point.

2.9 COOLING TOWER DRIFT PROGRAM l
l The Environmental Protection Plan requires a-study-to l
l determine the environmental effects of salt deposition from cooling tower drift. After reviewing suitable study, methods, GGNS personnel elected to conduct a' quantitative and qualitative cooling tower drift study which would-identify the salts deposited on vegetation in the surrounding environment and determine the quantity of each salt.
Salt Deposition Station Locations Eight sampling sites-were utilizedito measure cooling tower drift deposition. Six of the eight sampling sites were located in areas _where maximum salt deposition is predicted. These areas were extrapolated from the Bechtel Salt Deposition Model developed.for the GGNS Final Environmental Report. The remaining two sampling sites are control sites. The first is located southLof Raymond, Mississippi. An additional control site was'added at ,
Port Gibson, Mississippi, in 1985. Four of these sampling sites were equipped with replicate sampling devices. The-Heavy Haul Road and Glodjo locations had duplicate sampling.
devices which were not installed-unti'l 1985. The 1985 duplicates were established to1 strengthen the program's-statistical trend analysis and to' improve sampling,and analysis' quality assurance. The location of salt deposition sites are identified in Figures 2-4 and 2-5 and listed in Table 2-3.
RPT7224/SRESFLR 7
.c Fallout samples were collected in plastic buckets on a quarterly basis. The buckets were located four to six' feet above the ground, fitted with bird rings ~and-covered-with fine mesh screens to exclude-leaves and insects. ;
i Sample Analysis and Collection- !
j Samples were collected quarterly and analyzed for ten -
constituents:- ,
o Calcium o Magnesium-o Sodium o Iron-o Phosphate o Nitrate o Chloride- o Fluoride o Sulfate o Total dissolved 1 solids. ,
i These parameters were selected because past analyses have shown them to be prevalent in the Plant: Service Water System. Salt conntituents were also determined;for-the-demineralized water used in-the initial setup of_the collection buckets. Rainfall data was recorded for each sampling site.
Screens were= washed with deionized water, and the wash water volume measured-and deposited in-the. collector, on a quarterly basis. The volume of water in the collector'was then measured, and a composite sample: of_-the , collector's-contents was placed in a clean cubitainer', sealed and.
labelled. The date of removal,-total volume in:the collector, total-rainfall and location of the site were recorded on the appropriate data sheets.
Salt Deposition Rate Calculation Salt deposition rates (SDR):were calculated on a constituent-by-constituent basis from:
RPT7224/JNFFLR 8-
o The total volume of water contained in the sampling bucket o The concentration of a constituent in this water
.o The volume of demineralized water placed in the sampler initially o The concentration of the constituent in the demineralized water o The sampling area of the bucket.
Therefore, for a particular constituent, SDR = (VTT C) -
(V CD D) ,
A SDR = Salt Deposition Rate (mg/m 2) where:
V T = final sample volume (1)
C T = final sample constituent concentration (mg/1)
V D = seeded volume of demineralized water (1)
C D = demineralized water constituent concentration (mg/1)
A = collector area (m ).
I 2.10 METEOROLOGICAL SYSTEM The GGNS meteorological tower, with a base elevation of 156 feet above MSL, is approximately 5000 feet north-northwest of the GGNS Unit I reactor building, which has a-finished grade of 132 feet above MSL. The location of the meteorological tower is shown in Figure 2-6.
The-area around the meteorological towerfis flat and covered by grass. A county road passes the meteorological RPT7224/SRESFLR 9
tower approximately 400 feet to the north. The tallest structure, the GGNS Unit 1 natural draft cooling tower, is 522 feet high and is situated approximately 6000 feet south-southeast of the meteorological tower.
Due to its location in a relatively open-area and its proximity to GGNS, the tower site is expected to accurately represent the same meteorological characteristics as the region into which airborne material could be released from GGNS.
The meteorological system consists of duplicate sensors-(Channels A & B). Data recorded by meteorological instruments are stored in digital and analog forms via magnetic tape and strip charts. The following meteorological parameters are monitored by the system o Wind Direction o Change in Temperature (delta T) o Wind Speed o Dew Point o Temperature o Surface Precipitation.
Meteorological data was included in the Semiannual Radioactive Effluent Release Reports submitted to the U. S. Nuclear Regulatory _ Commission.
2.11 ENVIRONMENTAL EVALUATIONS l-The Environmental Protection Plan (EPP) foriGGNS-permits changes in GGNS design cn: operation and the performance of tests or experiments.that affect the environment, provided they do not involve a change _ist the i
EPP or an unreviewed environmental question. This means that changes, tests or experiments which do not affect the RPT7224/SRESFLR 10
._ _ _ . . . _ , . . _ _ . ~ . . . _ _ . . . _ . _ . , _ . _ _ . . _ . . _ . _ _
l environment are not subject to the requirements of the EPP.
Also, the requirements of the EPP do not relieve GGNS of the requirements in 10 CFR 50.59, " Changes,_ Tests and j Experiments," which address the question of safety I associated with proposed changes, tests and experiments.
Changes in plant design or operation and the performance of tests and experiments were reviewed by GGNS personnel for the possible effects they might have on the -
environment. When the review determined the change, test or experiment'could affect the environment, an environmental evaluation was prepared and recorded before additional' construction or operational activities associated with-the change, test or experiment were begun. However,-the EPP excluded changes, tests or experiments from the_ evaluations o If all measurable environmental effects;were confined

1 Review of changes, tests.and experiments at GGNS was-conducted by one of three groups:
o Nuclear Plant Engineering o Nuclear Operations o Nuclear Support.
The originating- organization performed .eut applicability determination on each proposed change, test or experiment to 4 l
ascertain if the activity might affect the environment.-
Only those which had'the potential to affect the environment' were required to receive environmental evaluations.-

SECTION 3.0 OBSERVATIONS AND DISC SSIONS
-RPT7224/SRESFLR 1-
3.1 SMOKE CONTEQL
! The GGNS Burn Pit, which was officially closed on February 22, 1990, was filled with dirt during the week of 1
June 11, 1990, thus prohibiting any future use.
3.2 EROSIOlLCpl{THQL The GGNS NPDES Permit requiree grab samples collected 4
from the outfalls of Sediment Basins A & B for total suspended solido (TSS) analysis. Normally, samples were not collected if prevailing meteorological conditions (such as heavy rain) could skew analysis results.
Analytical results are presented in Table 3-1.
Results from 1990 samples were consistent with TSS results j from previous operatienal years as shown in Figure 3-1.
This six year trend indicates that, overall, the basins function at similar efficiencies and that minimal erosion is occurring on the GGNS site.
3.3 TRANSMISSION LINE SURVEYS
- The aerial surveys in previous years have confirmed that soil and vegetation have stabilized along GGNS transmission lines. Therefore, as permitted by Section 4.2.1, paragraph 2, of the EPP, the Erosion Control Inspection Program was discontinued in 1988.
3.4 L12UID AND SOLID WASTE MANAGEMENT l 1
Licuid Waste GGNS did not incur any serious problems or incidents with liquid waste control in 1990. Liquids which were
, suitable for reuse were recycled through local contractors t
l and1 nonprofit organizations. Nonhazardous liquid vastes L
1
! RPT7224/JNFFLR 1
F (borated water, glycol and cooling water) were disposed of in the GGNS Resin Pond or discharged through National I
Pollutant Discharge Elimination System outfalls.
Solid Wasta Solid waste generated at GGNS during 1990 did not present any unanticipated problems or adversely affect the environment. Solid waste which was not salvageable was buried on site or at a local landfill.
Waste Management, Inc. has been contracted since 1988 for collection and disposal of solid waste from GGNS Unit 1 and the Energy Services Center. These consisted of office, warehouse, cafeteria and maintenance wastes.
Final disposal was at the Vicksburg landfill. ,
Hazardous Waste The Mississippi Department of Environmental Quality (MDEQ) inspected the Hazardous Waste Storage Area and related activitlec on March 29, 1990. The purpose of the inspection was to confirm regulatory compliance with the GGNS Hazardous Waste Management Permit. Each shipment was properly manifested and signed copies acknowledging shipment receipt were returned by the disposal facilities, folychlorinated.Bichenvis (PCBs) j No known exposure or offsite release of PCBs occurred-in 1990. l 1
i RPT7224/JNFELR 2 !
l
3.5 LAND MANAGEMENT AND WILDLIEE Based on field observations by ESP personnel, the 1990 operation of GGNS had no apparent ecological effect on the GGNS wildlife population. Common wildlife, such as i
deer, turkey and fish continue to be abundant based on hunting and sport fishing activities. Also, no adverse impact was observed on threatened or endangered species known or suspected to inhabit the GGNS site.
Land management practices continued as in past years.
Fields near the meteorological tower were used for agricultural production and mowing machines were used to maintain other cleared areas. The majority of the site can still be classified as predominantly hardwood forest.
Thus, diverse habitats were maintained to promote the wildlife population.
3.6 GROUNDWATER ,
Recional Groundwater Regional groundwater monitoring data is presented in Tables 3-2 and 3-3. Water levels recorded in 1990 were generally consistent with preoperational and operational data. This indicates the radial well pumping operation is 4 not affecting the regional water table.
A hydrograph for each regional well is provided in Figure 3-2.
RPT7224/JNFFLR 3
P_013th!El.Jhaui f e.r Perched groundwater data-is presented in Table 3-4.
A hydrograph for each perched aquifer well is provided in Figure 3-3. As indicated in Table 3-4, no water level exceeded 109.0 feet MSL during the 12 scheduled surveillances.
In addition to the 12 scheduled surveillances, ESP personnel made additional well measurements in support of Geotech's study of the DW-8 well. During this study, DW-8 and DW-6 exceeded the 109.0 feet MSL due to mechanical problems. DW-8's mechanical problems were reported in AECM-90/0062, dated April 16, 1990, and AECM-90/0083, dated May 8, 1990. DW-6's mechanical problem was reported' in AECM-90/0183, dated October 10, 1990. However, the problems were corrected and elevations returned below the 109.0 feet MSL. Well measurements taken during this study are included as Appendix 1.
Rainfall data for 1990 is presented in Table 3-5.
Figures 3-4 and 3-5 show yearly rainfall data from 1975-through 1990 and seasonal rainfall data from 1975 through 1990, respectively.
3.7 NPDES The 1990 monitoring results for all permitted outfalls were reported in the National-Pollutant Discharge Elimination System (NPDES) reports. The upriver temperature data required by the permit was also included RPT7224/JNEFLR 4
in each report. The Mississippi Department of Environmental Quality (MDEQ) and the U. S. Nuclear Requintory Commission received copies of these reports.
Several items noted during 1990 and included in the NPDES reports are summarized in the following o The following were routine discharges that occurred during the year. October discharges were to support activities during Refueling Outage No. 4:

Investigation by ESP personnel concluded that probable cause was dissolved oxygen depletion. A written report.(APO-90/0802) of the investigation by ESP personnel was sent to the MDEQ. A copy of this report is included in Appendix IV.
o A fish kill occurred on October 4 in Sediment Basin A. A written report (APO-90/0966) of the investigation by ESP personnel was sent to the MDEQ, who concurred (API-90/1014) with probable cause of fish kill as being dissolved oxygen depletion. A copy of this report is included in Appendix IV.
3.8 THERMAL MONITORING Thermal monitoring (Section 2.8) was conducted in February, August and December 1990 by ESP personnel. The results were organized so that temperature changes could be noted at specific distances from the river bank. No limit imposed by the NPDES Permit was exceeded. A summary l
of thermal monitoring conducted through-1990 is provided as Appendix II.

3.9 COOLING TOWER DRIFT During 1990, cumulative salt deposition samples were collected for four quarterly periods. Replicate samples were taken at four locations (Stations 1, 2, 5 and 6) as described in Section 2.9.
Table 3-6 presents the calculated salt deposition rates (SDRs) for the eight monitoring sites in the GGNS Cooling Tower Drift Program. These SDRs form the bases for the statistical analysis required by Section 4.2.2 of the EPP.
Section 4.2.2 of the EPP required the Cooling Tower Drift Program to begin at least 3 months prior to the operation of Unit I above 5% power and continued for three 1 years of operation. Section 4.2.2 further states that if 1 no statistically significant amounts of the analyzed components are detected during this time period, then a proposal can be made to the NRC to terminate the program.
In 1989 Nuclear Plant Engineering conducted an analysis of variance comparison between preoperational and operational data. The results of this comparison revealed that no statistically significant amounts of salt-were detected between preoperational and operational samples.
On February 19, 1991, GGNS submitted a proposal (GNRO-91/00029) to terminate the Cooling Tower Drift Program based on the results of the 1989 analysis.
RPT7224/JNFFLR 7 I . ... . . .
A statistical analysis for 1990 data shown in Table 3-6 has not been performed pending outcome of the termination proposal. Rainfall data collected at each sampling site is provided as Table 3-7.
3.10 METEOROLOOICAL DATA Meteorological data for the 1990 reporting period was included in the Semiannual Radioactive Effluent Release Reports submitted to the U. S. Nuclear Regulatory Commission. Data contained in these r0 ports is summarized in the following tables:
o Joint Frequency Distribution, 50 Meter Level (Table 3-8) o Joint Frequency Distribution, 10 Meter Level (Table 3-9) o Percent Bad Data Report (Table 3-10).
Table 3-11 shows the percent meteorological data recovery since 1986. This table indicates that the meteorological system is performing satisfactorily, as well as providing consistent data.
3.11 ENVIRONMENTAL EVALUATIONS During 1990, no unreviewed environmental questions were found. Environmental evaluations reviewed by Radiological & Environmental Services personncl were routine matters within the scope of expected activities. ,
No environmental consequences have been observed as a result of conduct of the activities evaluated. <

7 SECTION 4.0 ADMINISTRATIVE REQUIREMENTS RPT7224/SRESFLR 1
l 4.1 EPP CHANGES The GGNS Environmental-Program Plan'(EPP) had no .
changes or requests for changes during 1990. -The 1989 pending EPP amendment. request (PMI-89/04172). previously submitted to Licensing, was not transmitted to the NRC. j However, Licensing used this request as -justification - to the NRC in correspondence (GNRO-91/00029)1 dated February 19, 1991, for discontinuing the cooling tower drift monitoring requirements. The erosion control inspection monitoring requirements were discontinued in 1988.
However, in 1990 the EPP was implemented as written.
4.2 EPP NONCOMPLIANCES There were no EPP noncompliances during 1990.
Environmental Surveillance Program personnel successfully 1
conducted sampling and surveillance activities according- q to the EPP schedule. The required monitoring-program-was:
conducted without a reportable deviation.
4.3 NONROUTINE REPORTS Two unusual or important events occurred during 1990.
Flah kills occurred near the discharge point of Outfall: -
- 001 cnt August 16-17, 1990 and onsite Sediment Basin A on October 4, 1990. Investigation by ESPLpersonnel showed probable cause as dissolved oxygen depletion-in both instances. However, the dissolved oxygen depletion'was a natural occurrence and not related to station operation.
RPT7224/SRESFLR 1-
l
]
Assessment of these incidents'by ESP' personnel confirmed the aquatic effects were acute and confined to the general-area. No environmental' impact was observed outside of the affected area.
A summary report of these events was provided to the MDEQ and the-U S. Nucleer Regulatory Commission and is included as' Appendix IV.
4.4 POTENTIALLY SIGNIFICANT Ul' REVIEWED ENVIRONMENTAL: ISSUES There were no potentially significant unreviewed-environmental issues encountered in 1990. Changes in 4
station designiand operation, tests and experiments did I
~
- . not result in an unreviewed environmental question. Grand l Gulf Nuclear Station personnel made changes, tests and experiments in accordance with the EPP, paragraph'3,1, Plant Design and Operation.
Section 2,11 provides-a discussion:of.how the EPP, paragraph 3.1, is-implemented. Activities-at GGNS during 1990 which were related-to the EPP, paragraph 3.1, are discussed _in Section 3.11 of-this report. Completed 1990 environmental evaluations are included-as-Appendix III.

l THERMAL EONITORING REPORT
SUMMARY
Radiological & Environmental Services (R&ES) personnel established a program to monitor Grand Gulf Nuclear Station's (GGNS) liquid effluent temperature according to the National Pollutant Discharge Elimination System (NPDES). The 2.8 'C temperature change limit for water surrounding the mixing zone (Attachment I) was not exceeded.
METHOD Nuclear Plant Engineering (NPE) personnel surveyed the river bank to mark 72 reference points 100 feet apart (66 downstream and six upstream of the barge slip, Attachment I).
R&ES personnel conducted monitoring once in winter and once in summer when operating at 2 25% power. They used calibrated digital thermometers to obtain temperatures at a depth of five feet and at the surface. At each reference point, measurements were taken 100 feet from the river bank, then at ten-feet intervals until reaching the bank.
BACKGROUND Monitoring has been conducted 16 times, beginning in September 1982.
Four background measurements were made before GGNS was_ operational; five were made during winter operating conditions; and seven were mado during summer operating conditions.
Survey reference points that were monitored for each summer and winter period are shown in Attachment II. Temperature, river and plant operating data are summarized in Attachments III and IV. Discharge temperature, upriver temperature and percent power are shown-graphically in Attachment V. Ambient and Outfall 001 temperatures are shown in Attachment VI. Mississippi River stages are plotted in Attachment VII.
RBSULTS Since June 1986 (summer) the number of survey reference points monitored has been reduced as 'shown in Attachment II. This reduction occurred based on the fact that there were no significant temperature changes observed in the water surrounding the mixing zone.
The monitoring results (Attachments III and IV) show under normal summer flow and temperature conditions, the thermal plume rarely extended into the river and was usually confined to the barge slip and j mixing zone. Under normal winter cenditions, the thermal plume usually extended a few feet downstream.
j Radiological & Environmental Servicot personnel did observe that discharge outlet temperature readings recorded during the winter monitoring periods of 1986 and 1987 were the highest. However, upon investigation of the cause(s), we concluded it was a combination of river stage, ambient temperature, blowdown flow and percent plant <
power, with river stage being the most' dominant factor. The dominant effect of river stage on the discharge outlet temperature is further substantiated by the fact that the discharge pipe becomes uncovered at a river stage of approximately 20 feet (Vicksburg gauge).

Maximum temperature changes (delta Ts) relative to the upriver temperature are provided in Attachments-III and IV for the discharge outlet, barge slip outlet and surrounding water.- Discharge and barge slip outlet delta Ts are shown in Attachment VIII. The 2.8 *C delta T limit for water surrounding the mixing zone was not exceeded as shown in Attachments IX and X.
Delta Ts for the discharge outlet were obtained by subtracting the upstream river surface or 5 feet temperature reading, whichever gave the highest value, from the reading recorded in the discharge outlet.
Delta Ts for the barge slip outlet were obtained by subtracting the upstream river surface or 5 feet temperature reading, whichever gave the highest value, from the reading recorded.in the barge slip outlet.
Delta Ts for the surrounding water were obtained by subtracting the upstream river surface and 5 feet temperature readings from the. maximum surrounding water surface and 5 feet readings, respectively. The delta Ts shown in Attachments III and IV are shown as absolute values, therefore there were no negative numbers.
CONCLUSION A review of the thermal monitoring data shows the Mississippi River supplies a volume of water sufficient for dissipating the heated discharge from GGNS within the required mixing zone. Summer _and winter thermal _ monitoring data show the turbulence and volume of the Mississippi River mix the heated discharge and cause little temperature difference. The only area influenced by GGNS heated discharge is the barge slip and the associated entry into the Mississippi River, i

Basis: The Environmental Protection Plan (EPP) states that effluent limitation and monitoring requirements are contained in effective NPDES permit issued by the Mississippi Department of Environmental Quality (MDEQ) and the NRC relies on MDEO for regulation of these matters involving water quality and aquatic biota. The 100,000 opd sewage plant that is replacing the two existing sewage plants (30,000 opd each unit) will remain under the regulation of the MDEO. Since MDEO has inoicated no plans to change effluent limits on existing parameters in the new l NPDES Permit for the new sewage plant, there will be no change in the EPP.

GRAND Gl?LF NUCLEAR STATION tTNIT 1 CHANGES, TESTS OR EXPERIMENTS SAFETY AND ENVIRONMENTAL EVALUATION FORM B. Unreviewed Environmental Ouestion
[ ] Yes (J)Ho 1. Concerns a matter which may result in a significant increase in any adverse environmental impact previously evaluated in the Final Environmental Statement (FES) as modified by the NRC staff's testimony to the Atomic Safety and Licenwing Board
( ASLB), supplements to the tES, environmental impact appraisal, or in any decisions of the ASLB.
Basist Environmental concerns identified in the FES which relate to water quality.
matters are regulated by the GGNS NPDES Pe rmit . FES 5.6.3 states that " treated sanitary waste effluent from the station contains less than 20 mg/l of suspended solids and the 5-day biological oxygen demand (BODS). The NPDES Permit limits total suspended solids (TSS) and DOD5 to a daily average of less than 30 mg/l and to__
a daily maximum of 45 mg/1. The residual chlorine concentration of the sanitary ef fluent is between 0.1 mg/l and 0.5 mg/1."
These NPDES limits will not change in the new NPDES Permit, and therefore no localized effects in Basin A, Hamilton Lake or the Mississippi River are expected.
( ) Yes (J) Ho 2. concerns a significant change in effluents or power level.
Basist Sanitary wastes have no affect on power level. Sewage effluents have been combined from Outfall 010 (ESC &
Construction Sewage Plant) and Outfall 015 (Unit 1 Sewage Plant). The new Sewaae Treatment Plant will be labeled as Outfall 010, and it will be routed into Basin A.
The existing effluent from Outfall 010 will be increased to include the comparable flow from Outfall 015 which currently empties into Outfall 001.
Engineering estimates were provided to the Department of Environmental Quality. (Ref.
copy of permit application APO-90/0606.)
Based on this evaluation of physical and chemical aspects, no significant changes in effluents is anticipated, and therefore no affect on Sediment Basin A, Hamilton Lake or the Mississippi River is expected.

Grand Gulf Nuclear Station l Environmental Incident Report APO-90/ 0802 Dear Mr. Cain I have attached a report for the aquatic incident which occurred on August 16 and 17, 1990 near Grand Gulf Nuclear Station's (GGNS) NPDES Outfall 001.
Environmental Surveillance Program (ESP) personnel notified Mr. Louis Lava 11ee of this incident at 3:10 p.m., Friday, August 17, 1990.
ESP and Plant personnel's investigation of this incident has proven it was not caused by the operation of GGNS.
To comply with the reporting requirements of Section 5.4.2 of the GGNS Environmental Protection Plan, the Nuclear Regulatory Commission is notified by copy to the Regional Administrator. If you need additional information concerning this incident, contact Ms. Rita R. Jackson, Manager, Radiological &

ENVIRONMENTAL INCIDENT REPORT BACKGROUND At approximately 0800 hours0.00926 days <br />0.222 hours <br />0.00132 weeks <br />3.044e-4 months <br /> on August 17, 1990 Chemistry personnel notified Environmental Surveillance Program personnel of a fish kill near NPDES Outfall 001. Cooling tower blowdown (Outfall 002), liquid radwaste (Outfall 011) and plant service water (PW) return flow enter the Mississippi River via a barge slip at Outfall 001. Figure 1 depicts the fish kill area and the discharge pathway.
An area of ponded backwater, as indicated on Figure 1, above Outfall 001 contained the dead fish. A three to five ft channel connected the ponded area to the rest of the barge slip. As Figure 1 indicates, the ponded area was isolated from the direct flow of Outfall 001. The depth of the ponded area, when the fish kill was discovered, was approximately three feet at its deepest point. Due to the receding Mississippi River, the ponded area is now empty.
INCIDENT INVESTIGATION ESP personnel conducted a survey of the area to determine the extent of the fish kill. Of the 77 dead fish ESP personnel collected, approximately 10 were ,
collected in the channel of the barge slip with the remaining 67 collected in I the ponded area. ESP perconnel did not find any dead fish during their upstream and downstream Mississippi River surveys. The total weight of the collected fish, which are described in Table 1, was less than three pounds.
Figure 1 also depicts the water sample locations and Table 2 provides the analytical results. The following summarizes the analytical results.
Dissolved Oxygen 4.6 mg/l pH 7.25 - 8.02 Temperature 27.6 - 35.4*C Chemical Oxygen Demand 30 - 70 mg/l The analytical results were within expected values and not conducive to a fish kill.
Chemistry personnel's investigation of water treatment chemical additions revealed the following:
PSW blocide additions were secured from 1800 8-16-90 to 1200 8-17-90.
- The biocide addition to the cooling tower at 2100 on 8-16-90, which was the suspected cause, was not responsible for the fish kill. Proper chemical addition and confirmation of blowdown being secured before, during and following blocide addition was verified with plant logbooks, chart recorders and personnel interviews.
l
- Other chemical additions were accurate and within recommended guidelines.
DK2N5752.26/JRSFLR- 2
I '
, ENVIRONMENTAL INCIDENT REPORT (CONT'D)
CAUSE Based on our investigation and the fact that previous discharges and chemical l additions similar to those occurring during the August 16 and 17 period have been without incident. ESP personnel have concluded the fish kill was not caused by the operation of GGNS. We believe the fish kill was caused by the receding Mississippi River which led to unfavorable environmental conditions in the shallow ponded area where the largest concentration of dead fish was located.
ACTIONS TO PREVENT RECURRENCE Since the incident was not caused by plant activities but was caused by the receding Mississippi River, actions to prevent a recurrence are not necessary or planned.

Dear Ms. Jackson:
Re: HPDES Permit No. M50029521 Investigation Summary of Fish Kill in Sediment Basin A Our office has received and reviewed the report of ti.e referenced scatter as submitted by Entergy Operations on October l'2, 1990.
Based upon our review, wn have no reasons to not concur with the conclusion that the probable cause of this incident was due to occurrence.oxygen depletion, which may have resulted from a natural dissolved However, we do requent if there are any future occurrences of this nature in either Basin A or B, that samples be collected and analyzed for Total Organic Carbon and Chemical Oxygen Demand. For future reference and comparative purposes, we suggest the Basins be representative 1y tested for these parameters in the near future during norinal, unuvautful operating conditivus.
Also,'we acknowledge receipt of the Material Safety Data Sheets for the products used in Bechtel Shop Area. Your assistance in providing this information to us is approciated.
Please advise if there are any questions.
Sincerely.
