PREFACE The Annual' Environmental Operating Report'(AEOR) presents-the information and data obtained from the implementation of Grand Gulf Nuclear Station's (GGNS) Environmental Protection
. Plan'(EPP), Appendix BLto the GGNS Operating License (NPF-29),
for'the period January 1 through December 31,'1988. ' Historical information has also been included, where applicable, for ' comparison purposes.
.The GGNS 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 GGNS EPP.
1No aquatic issues were identified in the GGNS Final Environmental Statement. Consequently, none are addressed by' the GGNS EPP. Effluent limitations and monitoring re: .irements for aquatic matters are contained in the'GGNS National Pollutant Discharge Elimination System Permit issued by the Mississippi- I Department of Natural Resources (MDNR). The MDNR regulates . 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 scope of the EPP. This is done to provide a more comprehensive .
report for the Environmental Surveillance Proyram and to keep ! L the Nuclear Regulatory Commission informed of environmental l activities at GGNS.

INTRODUCTION Grand Gulf Nuclear Station (GGNS) is a nuclear power station operated by System Enargy Resources, Inc. (SERI), formerly Middle South Energy, Inc., and owned by SERI and Southwest Mississippi Electric Power Association (SMEPA). The station consists of one operating boiling water reactor rated at 1250 MWe and a similar unit on which constructi.'>3 has been suspended. 1.1 IMPACT ASSESSMENT AND
SUMMARY
The environmental impact of GGNS operational activities between January 1 and December 31, 1988 was monitored by the Environmental Surveillance Program (ESP). The monitoring results of the ESP contained in the following sections indicate the environment was not adversely impacted in 1988 by the operation of GGNS. No harmful effects or evidence of trends toward irreversible damage to the surrounding environment have been observed at GGNS. Overall, surveillance results for 1988 were comparable to those of previous years. Results remained within anticipated ranges and no adverse environmental impact was observed by ESP personnel. 1.2 GCNS SITE CHARACTERISTICS Grand Gulf Nuclear Station is located in Claiborne County, Mississippi, on the east bank of the Mississippi River, approximately 25 miles south of Vicksburg and 37 J20RPT870224 1
miles north-northeast'of Matchez. Grand Gulf Military PLrk 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 site. These lakes were once the channel of the i Mississippi River and average about five to seven feet in 1 depth. An area map showing the geographical location of GGNS is provided in Figure 1-1. Site _and Its Environs The site and its environs consis',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 1 plain region, while the Loess Hills portion varies from 80 to more than 200 feet above MSL. The property line shown in Figure 1-2 encompasses the 2300 acres originally purchased. However, due to erosion activity of the Mississippi River along the western boundary of the site, this acreage figure continually decreased until the river bank from the barge slip to the north boundary of the site was stabilized through the U. S. J20RPT870224 2
Army Corps of Engineero shoreline . modification program. I l Based on the GGNS Updated Final Safety Analysis Report, the ! current acreage figure for the site is approximately l 2100 acres. The site boundary is the same as the property line j 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 l railroads or navigable waterways traverse the site. Bald ) Hill Road, which was 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, which was formerly a county road, was closed to public traffic in 1 1986. Hamilton Lake Road traverses the site property in the north, north-northwest, northwest, west-northwest, and l West sectors. l l l Access The site area is accessible by two major highways: U. S. Highway 61 and State Highway 38, which connect Port 1 i Gibson (6 miles southeast of the site) with Natchez, Jackson and Vicksburg. l 1 l J20RPT870224 3 L

2.1 SMOKE CCNTROL Burning at GGNS has been confined to the burn pit located near the main (northeast) spoils disposal area. Burnable materials such as scrap lumber and paper were transported to the burn pit which is approximately 40 feet long, 10 feet wide and 12 feet deep. The pit has vertical walls of reinforced concrete, with a refractory lining and an air curtain destructor apparatus along the top of the j l south wall. Through the use of the air curtain device, i combustion of burnable trash was more efficient and smoke levels were routinely kept within the limits set by the Mississippi Air and Water Pollution Control Commission. Environmental Surveillance Program personnel made periodic inspections of the burn pit to ensure compliance with Mississippi air quality regulations. Uncontrolled burning and unauthorized fires were expressly prohibited. 2.2 EROSION CONTROL Erosion control at GGNS is a priority because of the . I proximity of GGNS to the Mississippi River, the hilly I terrain, the average annual rainfall of approximately 50 inches and the loess soils which are extremely susceptible to erosion. The methods which have been successfully utilized to control erosion are: o Revegetation of disturbed areas o Utilization of concrete chutes and flumes which channel runoff into two sediment basins, A and B (Figure 2-1). J20RPT870224 1
1 Sedimentation occurs in the basins, which helps to minimize the ecological effect on Hamilton Lake and the Mississippi j River. As a result of Amendment 7 to "GNS Construction Permit Numbers CPPR-ll8 and 119, dated December 23, 1981, monitoring and capacity requirements for the sedimentation basins were transferred to the GGNS NPDES Permit. I Environmental Surveillance Program personnel elected to continue runoff sample collection on a voluntary basis for r an additional period of time to gather supplemental data on basin sediment removal. Runoff sample collection r which 3 I was required prior to amending the Construction Perinits, l I was discontinued on January 31, 1985. Monitoring of sedimentation basins since January 31, 1985 has been conducted according to the parameters established by the GGNS NPDES Permit. .9 TRANSMISSION LINE SURVEYS The four transmission lines associated with GGNS (Figure 2-2) are: o Port Gibson Substation Line o Baxter Wilson Steam Electric Station Line o Franklin EHV Substation Line o Ray Braswell EHV Substation Line. The 115 kV transmission line from Port Gibson, Mississippi, supplies construction power and emergency power to GGNS. The 500 kV Baxter Wilson and Franklin transmission lines terminate in Warren and Franklin counties, respectively. J20RPT870224 2
The Ray Braswell line, a planned 500 kV transmission line, will connect GGNS to an existing 500 kV transmission line in Warren County. These lines were surveyed to observe vegetation growth and monitor erosion. If problem areas were identified, ground patrols made a closer observation. Recommendations were then made to the Mississippi Power & Light Company (MP&L) Engineering Department for corrective action. Problem areas were monitored during follow-up aerial surveys to determine the effectiveness of the corrective j actions. Techniques designed to minimize erosion have been l successfully used to reclear and control vegetation on 1 i transmission lines. Highway, surface water and railroad l l crossings were hand cut, usually leaving buffer strips l adjacent to the crossing. The use of heavy equipment in l clearing right-of-ways was limited to piling brush and pushing brush piles. Potential erosion areas were seeded and mulched. Synthetic erosion prevention material was utilized when necessary. The long growing season in the area provides excellent early root formation which also helps prevent damaging erosion. 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 l
.720RPT870224 3
{ L___ __ _ __ _ _ _
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. 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. l Construction scrap'and debris were collected in designated onsite areas for salvage, incineration or burial. Unusable combustible materials were burned on site in the burn pit. 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 WILDLIFE Approximately 2100 acres make up the GGNS site; 94 acres are fenced in the immediate plant area, with an i additional 37 acres set aside for permanent structures. ' The remaining acreage provides excellent habitat for Mississippi wildlife. Fringe areas and open fields were normally mowed two l times during each growing season to keep open areas from I being overtaken by scrub vegetation. After the growing l season, a series of small food plots were planted in these l
\
I J20RPT870224 4 l l
open fields to help sustain wildlife populations through the winter and early spring. A small fruit orchard and two gardens were also maintained on site by ESP personnel. Two lakes located on the site, Gin and Hamilton, were used for sport and commercial fishing by area residents. I 1 Utilization of the lakes and surrounding local lands by J l l water dependent species (waterfowl) was seasonal, with most activity occurring during fall and winter migrations. Hunting on site was limited ~to bow hunting for in- j season animals, pursuant to the requirements of Mississippi hunting laws. Othem hunting activities were prohibited on the GGNS site. 2.6 GROUNDWATER MONITORING The groundwater monitoring program was continued ] during 1988 at GGNS to: I o Provide data on the seasonal fluctuation of the ' regional groundwater table o Monitor the level of the perched groundwater table in the Units 1 and 2 Power Block areas. 1
)
Location of Monitoring Wells Twenty-seven wells were used to monitor the regional j 1 and perched groundwater underlying GGNS: j o Twelve wells for regional groundwater levels in the site area o Fifteen wells for perched groundwater levels in the Power Block areas. Locations of monitoring wells are shown in Figures 2-3 and 2-4 and listed in Tables 2-1 and 2-2 J20RPT870224 5
1 Regional Groundwater Wells used to monitor the regional groundwater levels j (Figure 2-3 and Table 2-1) were normally measured at least i twice a month. 1 Perched Groundwater GGNS Units 1 and 2 have a monitoring and dewatering system (Figure 2-4 and Table 2-2) located around the Power Block and the Standby Service Water Basins to monitor and ! dewater the underlying perched aquifer. Seven monitoring J wells (MW-1 through MW-7) were used to monitor the water levels in the perched aquifer, Eight dewatering wells _ (DW-1 through DW-8) were in place to dewater the aquifer if I water levels approached or exceeded the GGNS design basis l l elevation of 109 feet mean sea level (MSL). Water levels l in perched aquifer wells were observed and recorded once a month. 2.7 NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) , PERMIT National Pollutant Discharge Elimination System ; (NPDES) Permit No. MS0029521 was amended and reicsued to GGNS on June 1, 1982. The permit was issued in accordance with the provisions of the Mississippi Air and Water Pollution Control Law (Section 49-17-1, Mississippi Code of 1972) and the regulations and standards adopted and promulgated thereunder, and authority granted to the Mississippi Pollution Control Permit Board pursuant to
- Section 402(b) of the Federal Water Pollution Control Act.
J20RPT870224 6 l
l l l The permit as issued in June 1982 consisted of 15 outfalls, 1 but it was revised in May 1984 to add Outfall 016 and j combine Outfalls 008 and 009 into Outfall 007. 1 The permit allows GGNS to discharge wastewater,-in 1 accordance with NPDES regulations, into Hamilton Lake and , I 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 Natural Resources and the U. S. Nuclear Regulatory Commission via NPDES Monthly Reports. 2.8 THERMAL MONITORING PROGRAM Grand Gulf Nuclear Station's NPDES Permit requires that GGNS effluents and the Mississippi River mixing area j j be monitored to determine what effects, if any, will result from GGNS' 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) l 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 l 6000 feet downstream from the point of discharge, l as measured at a depth of 5 feet. The maximum a water temperature shall not exceed 32.2*C (90*F) outside the same mixing zone, except when ambient temperatures approach or exceed this value. Monitoring was conducted semiannually (once in winter and once in summer) when Unit 1 was operating at a minimum of 25% power. To initiate the thermal monitoring program and obtain baseline data, the river bank was surveyed to establish and J20RPT870224 7
permanently mark 72 reference. points 100 feet apart. Sixty-six of the reference' points are located downstream of GGNS' discharge into the river, and the remaining six are located upstream of the discharge. Calibrated digital thermometers were used 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 10 feet intervals until reaching the bank. This provided 20 temperature data points for eac'a reference point. 2.9 COOLING TOWER DRIFT PROGRAM The Environmental Protection Plan requires a study to l determine the environmental effects of salt deposition from cooling tower drift. After reviewing suitable study 1 i 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 utilized to 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 J20RPT870224 8
1 l 1 l l l control sites. The first is located south of Raymond, l l Mississippi. An additional control site was added at Port Gibson, Mississippi, in 1985. Four of these sampling sites were equipped with replicate sampling devices, and two of the replicate sampling sites had triplicate sampling devices. The Heavy Haul Road and Glodjo locations had duplicate sampling devices which were not installed until 1985. The 1985 duplicates were established to strengthen the program's statistical trend analysis and improve the sampling and analysis quality assurance. The location of salt deposition sites are identified in Figures 2-5 and 2-6 and listed in Table 2-3. Fallout samples were collected on a quarterly basis using buckets containing a known volume of deionized water. The buckets are located four to six feet above the ground, fitted with bird rings and covered with fine mesh screens to exclude leaves and insects. j Sample Analysis and Collection 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 solids. These parametirs were selected because past analyses have shown them to be prevalent in the Plant Service Water System. Salt constituents were also determined for the J20RPT870224 9
1 i i l demineralized water used in the initial setup of the f collection buckets. Rainfall data was recorded for each sampling site. Screens were washed with deionized water, and the wash I l water volume measured and deposited in the collector, on a l I 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 labeled. The date of removal, total volume in the
]
l collector, total rainfall and location of the site were recorded on the appropriate data sheets. i
}
Salt Deposition Rate Calculation Salt deposition rates (SDR) were calculated on a . 1 constituent-by-constituent basis from: o The total volume of water contained in the nampling bucket o The concentration of a constituent in this water i 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 = (V CT T) ~ Iv CD D) A SDR = Salt Deposition Rate (mg/m ) where: V T = final sample volume (1) J20RPT870224 10

' 1' l 2.10 METEOROLOGICAL SYSTEM ] The GGNS meteorological tower, with base elevation of 156 feet above MSL, is approximately 5000 feet north-northwest of the GGNS Unit 1 reactor building, which has a finished grade 132 feet above MSL. The location of-l t the meteorological tower is shown in Figure 2-7. The area around the meteorological tower is. flat and covered by grass. The nearest bluffs are approximately 362' i feet to the west of the tower, with trees 35 feet high along the bluffs. Approximately 400 feet to the east are trees greater than 50 feet high. To the south,-the nearest trees greater than 50 feet high are approximately 690 feet from the tower. A county road passes'the meteorological i tower approximat,1y 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 i region into which airborne material could be released from l GGNS. J20RPT870224 11 1
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 Effl ant Release Reports submitted to the U. S. Nuclear Regulatory Commission. 2.11 ENVIRONMENTAL EVALUATIONS The Environmental Protection Plan (EPP) for GGNS permits changes in GGNS design or operation and the performance of tests or experiments that affect the environment, provided they do not involve a change in the EPP or an unreviewed environmental question. This means that changes, tests or experiments which do not affect the 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 Experiments," which address the question of safety 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 J20RPT870224 12
1 i l s 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 I from the evaluation: o If all measurable environmental effects were confined to onsite areas previously disturbed during site preparation and plant construction, or l o If they were required to achieve compliance with other federal, state, or local requirements, j 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 an applicability determination on each proposed change, test or experiment to ascertain if the activity might affect the environment. Only those which had the potential to affect the environment j were required to receive environmental evaluations. 1 The originator of a proposed change, test or experiment completed an environmental evaluation or documented that one was not required. Completed environmental evaluations were I forwarded to the Radiological & Environmental Services (R&ES) Section in the Nuclear Support Department for an independent review. After providing independent review, the R&ES staff reported the results of environmental evaluations to the NRC in the GGNS Annual Environmental Operating Report. J20RPT870224 13

l i 1 i 1 l 1 l J l l 4 SECTION 3.0 OBSERVATIONS AND DISCUSSIONS l
'l J20RPT870224 i
3.1 SMOKE CONTROL During periods of_ operation, the GGNS burn pit was periodically evaluated for visible emissions by ESP personnel. The evaluations were unannounced and consisted of instantaneous opacity determinations by certified specialists. Monthly average opacity values and days of operation are provided in Table.3-1 and represented graphically in Figure 3-1. During the year, no opacity violations were noted. The yearly average opacity for the burn pit was 20%., There were 103 total days of observed operation. As shown in Figure 3-2, the total operating days of the burn pit in 1988 decreased, when compared to the past four years. This decrease is attributed to the contracting of Waste 3 1 Management, Inc. in 1988 for collection and disposal of sclid waste from GGNS Unit 1 and the Energy Services Center. Burn pit opacity was similar to that of previous years as shown in Figure 3-3. Based on 1988 monitoring, the operation and construction of GGNS have contributed no significant air emissions to the surrounding environment. 3.2 EROSION CONTROL Stabilization and revegetation of the majority of disturbed areas on the GGNS site have been accomplished. The only disturbed areas remaining which have not been J20RPT870224 1
l completely stabilized are the laydown and Unit 2 construction areas. Major construction areas associated with Unit 1 have been properly stabilized. Monthly grab samples were collected as required by the GGNS NPDES Permit from the autfalls of Sediment Basins A & B for total suspended solids (TSS) analysis. Samples were collected at times considered to be representative ~of the entire month and average' runoff conditions. -Normally, samples were not collected if prevailing meteorological conditions (such as heavy rain) could skew analysis results. r Analytical results are presented in Table 3-2. i Results from 1988 samples were consistent with TSS results from previous operational years as shown in Figure 3-4. 3.3 TRANSMISSION LINE SURVEYS The semiannual aerial survey of the GGNS transmission lines identified no major problem areas during 1988. Grand Gulf Nuclear Station transmission lines have well established vegetation. A detailed summary of the semiannual survey is provided in Appendix I. l Stabilization of soil and vegetation on GGNS-transmission line right-of-ways has progressed well, and sufficient ground cover is now available to preclude future serious erosion problems. Past and present semiannual transmission line surveys have established the following: o Construction practices were effective in minimizing environmental impact. ; J20RPT870224 2
~ _ _ _ _ _ - - - - - _ _ _ - _ _ - - _ - - _ .
o Erosion and vehicular damage caused by hunting and logging encroachment over the years has been minimal and caused no lasting problems. o Past remedial. action required to control erosion has been effective. The aerial survey in 1988 and previous. years have confirmed that soil and vegetation have' stabilized. Therefore, as permitted by Section 4.2.1, Paragraph 2, of the EPP, the erosion control inspection program was discontinued in 1988. 3.4 LIQUID AND SOLID WASTE MANAGEMENT Liquid Waste GGNS did not incur any sericus problems or incidents with liquid waste control in 1988. Liquids which were suitable for reuse were recycled through local contractors and nonprofit organizations. Nonhazardous liquid wastes (borated water and cooling water) were disposed of in the GGNS Resin Pond or discharged through National Pollutant Discharge Elimination System outfalls. Solid Waste Solid waste generated at GGNS during 1988 did not present any unanticipated probleres or adversely affect the environment. Unit 2 construction solid waste which was not salvageable was incinerated or buried on site without incident. J20RPT870224 3
Waste Management, Inc. was' contracted during 1988 for collection and disposal of solid waste from GGNS Unit 1 and-the Energy Services Center. These wastes consisted of office,, warehouse, cafeteria and maintenance' waste. Final disposal was at the Vicksburg landfill. Solid waste activities at GGNS during-1988.were in !- compliance with Mississippi Department of. Natural Resources, Bureau of Pollution Control, " Nonhazardous Waste Management Regulation," issued' September 1984. Hazardous Waste The Mississippi Department of Natural Resources (MDNR) inspected the Hazardous Waste Storage Area and related-activities on May 25, 1988. The purpose of the inspection was to confirm regulatory compliance with the'GGNS l Hazardous Waste Management Permit. Hazardous waste shipments for 1988 went to one of the-following facilities: o Chemical Waste Management - Emelle, Alabama o Rex Brown Steam Electric Station - Jackson, I Mississippi (waste oil only) i Each shipment was properly manifested and signed copies acknowledging shipment receipt were returned by the l disposal facility. ! Polychlorinated Biphenyls (PCBs) No known exposure or offsite release of PCBs occurred i in 1988. I J20RPT870224 4

i l .3.5 LAND MANAGEMENT AND WILDLIFE I l Based on field observations by ESP personnel, the 1988 - i operation of GGNS had no apparent ecologica1'effect on the l l GGNS wildlife population. Common wildlife, such as deer, q 1 turkey and fish continue' to be abundant based on hunting and sport fishing activities. Also, no adverse impact was-observed on threatened species known or suspected'to inhabit the GGNS site. Land management practices continued as1in past' years. l Fields near the meteorological tower were used for agricultural production and mowing machines were used to j l maintain other cleared areas. The majority of the site can- I still be classified as predominantly hardwood forest. Thus, diverse habitats were maintained to promote the wildlife population. 3.6 GROUNDWATER Regional Groundwater Regional groundwater monitoring data is presented in Tables 3-3 and 3-4. Water levels recorded in 1988 were l generally consistent with preoperational and previous operational data. This indicates the radial well pumping operation is not affecting the regional water table. A hydrograph for each regional well is provided in Figure 3-5. J20RPT870224 5
i l Perched Aquifer i Perched groundwater data is presented in Table 3-5. A
\
hydrograph for each perched aquifer well is provided in : I Figure 3-3. As indicated in Table 3-5, no water level exceeded 109.0 feet MSL during the.12 scheduled , surveillai.ces. Rainfall data is presented in Table 3-6. 3.7 NPDES The 1988 monitoring results for permitted outfalls were reported in the National Pollutant Discharge Elimination System (NPDES) reports. The upriver temperature data required by the permit was also included in each report. The Mississippi Department of Natural Resources (MDNR) and the U. S. Nuclear Regulatory Commission received copies of these reports. Several items noted during 1988 and included in the NPDES reports are sumnarized in the following: o The following were routine discharges that occurred during the year: Date Quantity Source l 4/5 1,250 gal. Div. I Diesel Cooling 1 Water Jacket 1 4/22 300,000 gal. Fire Water Storage Tank 6/6 60 gal. Div. I Diesel Cooling Water Jacket 7/17 500 gal. Div. I Diesel Cooling Water Jacket All discharges were within NPDES limits. J20RPT870224 6
o From June 19 - 25, approximately 300,000 gallons of water / sulfate-reducing bacteria sludge'from Standby Service Water Basins A & B (Outfalls 004 and 005) was discharged into Sediment Basin B. Verbal and written approval for the discharge was provided by the ; Mississippi Department of Natural Resources (MDNR). Additionally, during Refueling Outage No. 2 the i Standby Service Water (SSW) System was cleaned with a mixture of tannin and citric acid. Negotiations were conducted with the Mississippi Department of Natural , l Resources to ensure disposal of the cleaning water was j i accomplished in the most economical and environmentally j l acceptable manner while utilizing existing facilities. In I l order to allow reduction of suspended solids and adequate l time for confirmation of physical characteristics, the Unit 2 cooling tower basin was used as an interim holding area. The SSW cleaning water subsequently infiltrated to the sa'id substructure of the cooling tower basin and no discharge to surface water was necessary. Subsequent monitoring by. ESP personnel of Stream A, Sediment Basin A and groundwater showed no adverse effects. 3.8 THERMAL MONITORING Thermal monitoring was conducted in February and August 1988 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 of thermal monitoring conducted through 1988 is provided as Appendix II. J20RPT870224 7

-i 3.9 COOLING TOWER DRIFT During 1988, cumulative salt deposition samples were collected;for four quarterly periods. Replicate samples j 1'
were taken at four locations-(Stations 1, 2, 5 and 6) as described in Section 2.9. Table 3-7 presents the calculated salt deposition rates (SDRs) for the eight monitoring sites in the GGNS q J Cooling Tower Drift Program. These SDRs. form the bases for 1 the statistical analysis required by SectionL4.-2 of the. EPP. This' analysis was performed by GGNS Nuclear Plant . l Engineering and is presented in Appendix III. Rainfall data collected at each sampling site.is provided as Table 3-8. l 3.10 METEOROLOGICAL DATA l Meteorological data for the 1988 reporting period was. included in the Semiannual Radioactive Effluent Release Reports submitted to the U. S. Nuclear Regulatory Commission. Data contained in these reports is summarized' i in the following tables: o Joint Frequency Distribution, 50 Meter Level (Table 3-9) o Joint Frequency Distribution, 10' Meter Level-(Table 3-10) , o Percent Bad Data. Report (Table 3-11). I Table 3-12 shows the percent meteorological data recovery since 1986. This table indicates ttat the i meteorological system is performing satisfactory, as well- I as providing consistent data. J20RPT870224 8
3.11 ENVIRONMENTAL EVALUATIONS During 1988, no unreviewed environmental questions were found. Environmental evaluations reviewed by Radiological and Environmental Services personnel were routine matters within the scope of expected activities. No environmental consequences have been observed as a result of conduct of the activities evaluated. A completed copy of each 1988 environmental evaluation recorded by R&ES is included in Appendix IV. An analysis, interpretation and evaluation of the environmental inpact of each change, test or experiment is made in each environmental evaluation. Table 3-13 summarizes the evaluated items.

TABLE 3-13 1988 ENVIRONMENTAL EVALUATION
SUMMARY
Identifying Number Description NSSE-88/001 ODCM, Rev. 11, is necessary to reflect- j change in operator of GGNS from MP&L to j SERI, insert antimony dose factors, clarify l use of X/Q and D/Q for tritium and ground plane calculations, and update radiological environmental sampling locations. NSSE-88/002 ODCM, Rev. 12, is necessary to revise gaseous setpoint calculation methodology. Rev. 12 increases flexibility in setpoint adjustment, eliminates an unnecessary calculation and clarifies the setpoint calculation methodology. 004/88 Temporary directive provides for operation of the offgas system with a minimum of one charcoal train in service and with the first bed in the operating train bypassed. Nitrogen purging of bypassed beds may continue while in this mode of operatica. 022/88 Water samples taken from each SSW basin show a 4" to 6" layer of sediment on the bottom of all basins. This activity will vacuum this sediment from the basin floors. The sediment water mixture will be pumped to a storm drain. 036/88 Change to UFSAR Chapter 11.2 to reflect the current methods used in processing liquid radwaste. This system was originally designed for maximum recycle of wastewater to the condensate storage tank. Instead of discharge of 10% of floor drain wastes per year as described in the UFSAR, C-GNS may discharge up to 100% of floor drain l wastes. To ensure that discharges conform 1 with 10CFR50, which requires such releases to be "as low as reasonably achievable," all discharges are monitored in accordance with Technical Specifications 4.11.1.1, 4.11.1.2 and the Offsite Dose Calculations Manual. l 1 J20RPT870224 26 I i _ _ _ _ _ _ _ _ _ _ _ _ _ _ .___ l

4.1 EPP CHANGES, There were no changes or requests for changes to the GGNS Environmental Protection Plan-(EPP) during 1988. Alue, there are no license amendments, eithet ding or planned, which would change the EPP. In 1988, the EPP was 1 implemented as written. ! 4.2 EPP NON-COMPLIANCES There were no EPP non-compliances during 1988. Sampling and surveillance activities were successfully conducted according to the EPP schedule The required monitoring program was conducted without a reportable deviation. 4.3 NON-ROUTINE REPORTS There were no non-routine events that occurred during 1988. The underground sulfuric acid spill discussed in the 1986 and 1987 Annual Environmental Operating Reports was stabilized in 1988 using a chemical solidification process. A request to discontinue monitoring water level elevations and pH around the acid-affected area was made to the Mississippi Department of Natural Resources (MDNR) in correspondence (APO-88/0771) dated August 3, 1988. The MDNR authorized discontinuing monitoring in correspondence dated January 17, 1989. l l f J20RPT870224 1

~l 4.4 POTENTIALLY SIGNIFICANT UNREVIEWED ENVI.RONMENTAL ISSUES There were no potentially significant unreviewed environmental issues encountered in 1988. Changes in station. design and operation, tests and experiments did not result in an unreviewed environmental question. Changes, tests and experiments were made in accordance with the EPP, Paragraph 3.1, Plant Design and Operation.
Paragraph 2.11 provides a discussion Of how the EPP, Paragraph 3.1, is implemented. Accivities at GGNS during i 1988 which were related to the EPP, Paragraph 3.1, are i discussed in Section 3.11 of this-report.

SUBJECT:
Aerial Survey of Transmission Lines Associated with Grand Gulf Nuclear Station (GGNS) DATE: July 19, 1988 NSIM-88/0187 On June 9,1988 the first semiannual aerial survey of the GGNS transmission lines for 1988 was conducted by Mr. G. W. Guider, Mr. J. T. Bankston and Mr. L. K. James. The following transmission lines were surveyed:
- 500 kV GGNS to Baxter-Wilson Steam Electric Station
- 500 kV GGNS to Franklin Substation
- 115 kV GGNS to Port Gibson Substation
- 500 kV GGNS to Ray Braswell (proposed)
No erosion problems were identified along these transmission corridors and revegetation continues to be excellent.
Danger trees" are evident from the old GGNS railroad track at Oil Mill Road (formerly Two-Mile Bridge Road) to the 115 kV substatica at Port Gibson. The " danger trees" observed would probably cause a circuit outage, but not cause the line to fall. A memorandum (SEMP-88/0003) has been transmitted to Mr. M. D. Hennington (MP&L) requesting action.
The next survey is scheduled for Fall 1988, i i i' GWG/GEA:bcb cc: Mr. M. D. Hennington (MP&L) Mr. O. R. Hutchinson Dr. L. R. McKay , Mr. T. E. Reaves, Jr. File (ENV) [1] File (NS)[1] File (R&ES) I 1 l ls PENV AERIAL SURVEY /880609 I
AFPENDIX 11 THERMAL MONITORING
SUMMARY
k l l t J20RPT870224 - II-i
( l l , THERMAL MONITORING REPORT d i
SUMMARY
l Radiological & Environmental Services (R&ES) personnel established a l 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. 1 BACKGROUND Monitoring has been conducted 12 times, beginning in September 1982. l Four background measurements were made before GGNS was operational; I three were made during winter operating conditions; and five were I made during summer operating conditions. l Temperature, river and plant operating data are summarized in Attachments II and III. Discharge temperature, upriver temperature and percent power are shown graphically in U.tachment IV. Ambient j and Outfall 001 temperatures are shown in Attachment V. Mississippi j Fiver stages are plotted in Attachment VI. METHOD Nuclear Plant Engineering (NPE) personnel surveyed the river bank to ) mark 72 reference points 100 feet apart (66 downstream and six j upstream of the barge slip, Attachment 1). R&ES personnel conducted monitoring once in winter and once in summer when operating at > 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 i feet from the river bank, then at ten-foot intervals until reaching I the bank. RESULTS f The monitoring results (Attachments II and III) show that under normal summer flow and temperature conditions, the thermal plume rarely extended into the river and was usually confined to the barge slip. Under normal winter conditions, the thermal plume usually extended a few feet downstream. Maximum temperature changes (delta Ts) relative to the upriver temperature are provided in Attachments II and III for the discharge outlet, barge slip outlet, mixing zone and surrounding water. Discharge and barge slip outlet delta Ts are shown in Attachment VII. The 2.8 *C delta T limit for water surrounding the mixing zone was not exceeded. 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 turbuience 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.

n i STATISTICAL ANALYSIS 0F ! GRAND GULF DEPOSITION DATA Discussion ! The Grand Gulf Nuclear Station (GGNS) has an extensive network of monitoring stations used for assessi.e plant impacts and for gathering basic data, including j meteorological. Salt deposition samplers (SDS) have been installed at six nearby. ' site stations and two distant control sites. During 1988, cumulative samples were collected for four quarterly periods. Replicate samples were taken at two sampler locations (stations 2 and 5). For each sample, analyses have been 3 conducted on ten salt parameters: sodium, iron, calcium, fluoride, nitrate, chloride, magnesium, sulfate, phosphates, and total dissolved solids (TDS). ! Tsble 1 gives the salt deposition rates provided by GGNS Radiological and Environmental Servicec which form the bases for the statistical analyses discussed below. Presently, the data base is not very extensive (on a year to year basis) and doubt can be cast on the validity of some of the data. Nevertheless, quantitative estimates of the precision of the data and the relative importance of the various factors which can potentially influence salt 1 deposition rates can be obtained. The former can be quantified by estimating confidence limits for the various data; the latter by statistically analyzing the i data by Analysis of Variance (ANOVA). The present statistical analysis uses a { two-factor ANOVA which involves calculating F-factors and conducting significance j tests for major potential influences (period, location and the interaction of j the two). j The basic statistical model selected for the analysis is as follows: M+P + R gj + D ijk
=
g
+ L j ek (ij) where D = basic SDR (Salt Deposition Rate) data M = mean SDR P
g
= contribution due to sampling period L = contribution due to sampling location PL = contribution due to sampling period and location Id interactions e = error due to sampling, analytical, etc. techniques and
) other, unaccounted for, factors Interactions and "experime tal" error can be separated in a multiple-factors experiment only if multiple observations are taken at various combinations of sampling periods and sampler locations. Determining confidence limits for the basic SDR date depends on the estimate of " experimental" error for the model; this estimate, in turn, depends on the availability of replicate samples. Since the latter were obtained only for SDS locations 2 and 5, this statistical analysis will consider only these two locations.
NCIREP STATISTICAL ANALYSIS
2 For simplicity's sake, a complete balanced block design will be considered; that ) is three replicate SDRs for each combination of periods (four) and locations I (two), or a total of 24 SDR data points for each constituent. The actual data block is incomplete since some SDR data are either not available or are obviously biased. Pseudodata points have been estimated based on available data j for the same sampler to complete the data block. Table 2, giving the SDR data, includes these pseudodata points. Calculation Number CC-N1000-89020 was performed for this analysis. Basically one i calculates the sum-of-squares for each of the factors of interest (period, location, period-location interaction, and error). Then the F-factors for period, location and period-location interaction relative to basic error are determined as well as an estimate of the confidence limits for the average SDR for any given period and location. For the purposes of this analysis, 95% confidence limits and 95% significance critical F-factors have been considered. Using standard student -t and F distribution tables, other levels of significance are readily determinable, if required. Table 3 summarizes the results of this analysis. Result of the ANOVA (Table 3) for sampler locations 2 and 5 (with replicate samples) show interaction of sampling period and locstion on some of the SDRs. As noted earlier, multiple observations are required to separate interaction and
" experimental" error. Even when multiple observations are not available, ANOVA analysis can scill be performed to evaluate the main effect of an individual factor. Therefore, the two-f actor ANOVA (without replicates) can be performed for the other sampling locations (other than 2 and 5) to evaluate the effect of location and period. Table 4 shows salt deposition data (five locations, four periods) for the ANOVA analyses without interaction. This ANOVA calculation was also performed in calculation number CC-N1000-89020.
To help analyze impacts of environmental factors such as rainfall, wind speed, prevailing wind direction and resultant wind direction, a linear regression analyses may be performed as follows: (1) Cumulative rainfall for the period versus the salt deposition rate for that period (for all salt deposition rates for sampler locations 2 and 5) (2) Average wind speed for the period versus the salt deposition rate for that period (as above) (3) Prevailing wind direction for the period versus salt deposition rates for that period (as above) (4) Resultant wind direction for the period versus the salt deposition rate for that period (as above) l For each of the four sampling periods, data f or rainf all and the frequency distributions for wind speed and direction have been obtained by reduction of the CGNS weather data. Table 5 summarizes these four environmental factors. l NCIREP STATISTICAL ANALYSIS
3 Data points for a regression analysis on a SDR parameter consist of data pairs as follows - an environmental factor for a period and' corresponding SDR value of the parameter for the period. The SDR data from sampler locations 2 and 5 were used for the regression analyses. Table 6 gives the correlation coefficients (for each SDR parameter with each environmental factor) as obtained from the regression analyses. Conclusions (1) The results of the three-way ANOVA based on salt deposition rates indicate the following: (Table 3) Sampling period has significant influence on all SDR parameters. i Sampling location had a significant influence on calcium, nitrate, ; phosphate, and Total SS. j
\
Interaction of sampling period and location had significant influence on calcium, magnesium, sodium, fluoride, phosphate, and Total SS. (2) Two-way ANOVA results (Table 4), assuming no interaction between period and location, indicate the following: Sampling period had an influence on 9 of the 10 SDR parameters. Sampling location had an influence on three parameters. (3) Results of linear regression analyses (Table 6) indicate the following: Significant linear correlation between rainfall and 5 of the SDR parameters is 'ndicated. Average wind speed sbowed significant linear correlation with 6 of the SDR Parameters. Prevailing wind direction showed significant linear correlation with 6 of the SDR Parameters. Resulting wind direction showed no significant linear correlation with 5 of the SDR Parameters. Recommendations t
- 1. Results of 0.00 should be avoided. The result should be reported at the detection limit of the method.
- 2. A qualitative, semi-quantitative or quantitative phenomenological model 1 describing salt deposition in a general sense should be developed to utilize the monitoring program's data appropriately. Which of the three models is developed should depend on the uses of the analytical results, the precision and sensitivity required in assessing impacts, and the criticality relative to Grand Gulf Nuclear Station Licensing.

- 3. To obtain better quantification of random sampling / experimental errors, replicate samples should be obtained at all locations and analyzed using exactly the same analytical methods.
- 4. To determine the effect of the cooling tower, data on circulating water composition may be used in conjunction with the SDR and data on the cooling tower operating conditions and duration.

SUBJECT:
1988 Salt Deposition Statistical Analysis DATE: February 27, 1989 PMI-89/ 01483 Please perform a statistical analysis on the attached 1988 salt deposition data. In addition, please determine if statistically significant amounts of salts, at the 95% confidence level, were obtained between the preoperational and operational samples. Such a determination is required by Section 4.2.2 , Paragraph 4, of the Environmental Protection Plan before the salt deposition program can be terminated. Analysis results should be returned to Ms. Rita Jackson by April 1, 1989 for inclusion in the 1988 Annual Environmental Operating Report. If there are any questions, please contact Ms. Jackson at 984-9366.

the barge slip between the discharge pipe and the outlet intovelocity The flow the riveratwill the f contain water at an average depth of 3.4 m (11 ft). outlet of the barge-slip channel will be about 0.03 m/s (0.1 fps). 4.2.5 Radioactive-Waste-Management System Under requirements set by Section 50.34a of Title 10 of the Code of Federal Regulations (10 CFR), an application for a permit to construct a nuclear power reactor must include a preliminary design for equipment to keep levels of radioactive materials in effluents to unrestricted areas as low as is reasonably The term ALARA means as low as is reasonably achievable achievable (ALARA). taking into account the state of technology, as well as the economics of improvements in relation to (1) benefits to the public health and safety and other societal and socioeconomic considerations and (2) the utilization of atomic energy in the public interest. Appendix I to 10 CFR Part 50 provides numerical guidance on design objectives for light-water-cooled nuclear power reactors to meet the requirements that radioactive materials in effluents released to unrestricted areas be kept ALARA. To meet the requirements of 10 CFR Section 50.34a, the applicants provided final designs of radwaste systems and effluent control measures for keeping. levels _ of radioactive materials in effluents ALARA within the requirements of Appendix I to 10 CFR Part 50. In addition, the applicants provided an estimate of the quantity of each principal radionuclides expected to be released annually to unrestricted areas in liquid and gaseous effluents produced from normal opera-tion (including anticipated operational occurrences). The NRC staff's detailed evaluation of the radwaste systems and the capability of these systems to meet the requirements of Appendix I is presented in Chapter 11 of the staff's Safety Evaluation Report. The quantities of radio-active material that are now estimated to be released from the plant (ase calculated by the NRC staff) are presented in Appendix D of this statement, along with examples of the calculated doses to individual members of the public and to the general population resulting from these effluent quantities. As part of the operating license for t'his Station, the NRC will require Technical Specifications limiting release rates for radioactive material in liquid and gaseous effluents and requiring routine monitoring and measurement of all principal release points to ensure that the Station operates in conformance with the radiation dose design objectives of Appendix 1. 4.2.6 Cooling-Tower Blowdown As a consequence of adding the radial-well intake system, the quality of the cooling-tower blowdown will differ from that described in the FES-CP. Evapora-tion of water in the cooling-water system (CWS) results in an increase in the concentration of chemicals and solids present in the water. The applicants have computed the concentrations of the chemicals in the CWS blowdown under a range of operating conditions. Table 4.1 shows average blowdown quality during operation at three cycles of concentration. Sulfuric acid will be added to control scale formation, and polyphosphates will be added to act as a calcium dispersant. Table 4.2 presents the concentrations of sulfates, chlorides, and 4-5

ENVIRONMENTAL EVALUATION ID- # 022/88 DESCRIPTION Water samples taken from each SSW Basin show a 4" or 6" layer of sediment on the bottom of all basins. This activity will vacuum this sediment from the basin floors. A diver with portable vacuum / dredge will enter the basins to accomplish this. The diver will have his air supplied by an air pump located at ground level. Additionally, communications will be maintained between the diver and the support
. crew. Lighting will be secured to the diver. Air hoses and a tether will be connected between the diver and air pump. The vacuum / dredge is hydraulically powered from a pump also on the ground level. The vacuum / dredge will also be tethered. There will only be one diver and vacuum / dredge in one SSW Basin at any time. No other equipment will be necessary to accomplish this activity. The sediment water mixture i will be pumped to a storm drain.
JUSTIFICATION The material on tne basin floor provides an environment for microbiological growth and hydrogen sulfide production. The layer is estimated to be 4" to 6" thick. Removal of this material will enhance our proposed basin cleanup and sterilization program aimed at regaining microbiological control of S51 1 BIOCIDE CONCENTRATIONS I At the time the vacuum process begins, 21 days will have elapsed since the last biocide addition was made to either basin. For the past year ) Betz PL-3631 biocide has been used in both basins at a concentration ! of 15 ppm. This biocide contains: Dodecylguanidine hydrochloride l (DGH, 10%), Methylene bis thiocyanate (MBT, 5%). Half lives of these twoproductsare<12hoursunderSSWconditigs. At 12 hours half life and 21 days since last addition, (12/24) = 4.7 E-7. Therefore, no biocide will be present. WASTEWATER CHARACTERISTICS Physical - Appearance will be " murky" to black.

EUTROPHIC CONSIDERAT!0NS High levels of inorganic nitrogen andThe phosphate chemicaland the presence analysis of (MTI-88/0312) trace metals are not anticipated.
- l of the wastewater indicates these materials will not be in concentrations high enough for Sediment Basin B or Hamilton Lake to become nutrient rich or eutropic. Additionally, dissolved oxygen levels in the basin are approaching maximum and BOD levels.of the wastewater are not excessive. Consequently, algal " blooms" and their subsequent death and decay with deoxygenation of the lower water strata are not anticipated.
. Futhermore, these analyses results were provided to the Mississippi Department of Natural Resources (MDNR). After reviewing the analyses results, the MDNR has authorized the discharge.
)
MICROBIAL' CONSIDERATIONS The anaerobic mircobial population of this wastewater is a sulfate-reducing bacteria. This species is indigeneous in most naturally l l occurring environments. They are not known to be the causative agent ' of any aouatic disease. Furthermore, these microbes are being introduced to aerobic conditions which will rapidly reduce the l population. The aerobic microbial population is composed of Pseusdomonas species. These species are naturally occurring and could be anticipated in this type of environment. Microbiological test results are attached. These results were ' discussed with two microbiologists as outlined in the attached Telephone Conversation Records (MTO-88/0423 and MT0-88/0424). No significant adverse environmental consequences were identified by ' these microbiologists. AQUATIC BIOTA CONSIDERATIONS Sediment Basin b was estimated to be 600' x 150' with an average depth of approximately 1.3'. Based on these dimensions, the volume of Sediment Basin B is 870,000 gallons. At a discharge rate of 50,000 gal / day, less than 6% of the basin volume will be displaced nach day. A review of the chemical analysis shows that no toxic metals or organics are present. Also, the level of biocide will be zero based on the product half-life as previously discussed. Suspended solids are anticipated to' compose approximately 20% of the wastewater volume. This 20% will be the sludge which is being vacuumed from the bottom of the SSW Basin. The other 80% will be SSW water. Analysis results for the sludge and SSW water are attached. The wastewater will be discharged to the storm sewer which normally i has a flow rate of 50 gpm. Consequently, as the wastewater enters Sediment Basin B the sludge will account for less than 14% of the total. PENV SAFETY & ENV EVALUATIONS - 2
1 AQUATIC BIOTA CONSIDERATIONS _(Cont'd) Due to the length of Sediment Basin B, most of the suspended solids will settle out within the first 200 feet. While aquatic biota in ; this first 200 feet will probably undergo stress, there will be sufficient unaffected areas remaining to support the population. : q ENVIRONMENTAL CONSEQUENCES Based on this evaluation of the various physical and chemical aspects 1 of this wastewater discharge, there will be no effect on Hamilton Lake and minimal, if any, affect on Sediment Basin B. While the suspended solids may cause some loss of aquatic life, it will be contained to the influent end of Sediment Basin B and should occur only at the start of the discharge. Consequently, no significant environmental consequences or lasting environmental degradation is anticipated. fupporting this coriciusion is' the independent review conducted by the MDNR in order to authorize this non-routine discharge. The MDNR's review (PMI-88/0312) did not identify any areas of concern either. 4 I PENV SAFETY & ENV EVALUATIONS - 3

Whitney File (Central) [ 6 ] X Information Only File (ENV) File (NS) l Summary of Conversation l l On 6/3/88 I met with Mr. Hamil to discuss Plant Staff's request to discharge 2 100,000 gallons water / sulfate reducing bacteria sludge from each SSW Basin through the storm drain system to Basin B. I provided him the water and deposit analyses (attached) and asked him to review it. He requested that we collect samples for 800 analyses. At that time he felt we could go ahead and discharge with no problems. 1 called Mr. Hamil on 6/14 and provided him the BOD results (attached) from the SSW Basins. He asked if we could take some Dissolved Oxygen (00) readings from Basin B and Hamilton Lake. He also wanted to know if the discharge would take place over a long period of time or in one day. Mr. Hamil returned my call on 6/15 and I provided him the following D0 readings taken by R&ES: Basin B (influent) 8.3 l Basin B (middle) 9.4 Basin B (effluent) 10.4 Hamilton Lake (entrance) 9.1 Hamilton Lake (exit) 3. 7 I also told Mr. Hamil that the discharge would take place 4 days per Basin working 8 hours / day. (This info provided by Mr. Richard Ducker). Mr. Hamil was also told that the discharge may be as much as 150,000 gallons per Basin. Mr. Hamil gave verbal permission to discharge the water / sulfate reducing bacteria sludge to the storm drains.

Dr. Pabst said that the SRB in question, (Desulfovibrio desulfuricans), is a normal part of pond sediments and that an injection of sludge containing this SRB into Basin B should have no direct adverse impact due to the SRB. Dr. Pabst did outline two scenarios in which an adverse impact could occur, but based on his past experience he thought the possibility of either scenario occurring would be highly improbable. _,High TSS levels could have an adverse impact on the fish respiration. Nitrification of Basin B due to the sludge could
~
cause an algae bloom and subsequent de-oxygenation of the basin. (This should not occur because analysis have shown near zero levels of nitrates and phosphates in the sludge.) RLC:bcb 6 O e a u ne %r m ::nc i

Darnell, Environmental Protection Systems, on 6/13/88. Mr. Darnell said that the majority of the bacteria (SRB) would be killed during pumping operations due to aeration of the sludge enroute to Basin B. In further conversation, Mr. Darnell also indicated that the SRB in question (Desulfovibrio desulfuricans) is normally found in natural soil formations and pond sediments. The only adverse effects mentioned by Mr. Darnell is the possibility that the SRB could regenerate in anaerobic pockets in sufficient quantities to produce high levels of Hydrogen Sulfide gas. He did not think that this would happen because of the small volume of waste sludge to be disposed. RLC:beb x n::. y ..

l Attachment-to Safety Evaluation 036/88 l The proposed changes to UFSAR Chapter 11.2 update this section to reflect the current methods used in processing liquid radweste. ) l This system was ot4ginally designed for maximum recycle of waste water to the condensate storage tank. I Due to the poor water quality of floor drain wastes (i.e., inleakage from PSW which typically has a conductivity range from 250 to 500 paho;;high total organic carbon levels; chemical. additions which are non-ion exchangeable), it is not cost effective to perform the amount of cleanup required to restore this water to condensate quality. Major modifications to our current water treatment system would be necessary in order to achieve a level of discharge as currently described in the UFSAR. Therefore, instead of discharge of 10% of floor drain wastes per year as described in the UFSAR, GGNS may discharge up to 100% of floor drain wastes. To ensure that discharges conform with 10CFR50, which requires such releases to be "as low as reasonably achievable", all discharges are monitored in accordance with Technical Specifications 4.11.1.1, 4.11.1.2 and the Offsite Dose Calculations Manual. Review of past effluent reports show that GGNS has maintained doses to the public/ individuals below the limits of 10CFR50 while discharging 100% of floor drain wastes.
- a. The proposed changes to the UFSAR do not require a change to Technical Specifications. No changes are made to any radioactive liquid effluent monitoring instrumentation as described in T.S.
3.3.7.11. The' concentrations of radioactive materials released-in, liquid waste effluents will remain below the concentrations' specified in 10CFR20 and result in exposures within the objectives of 10CFR50 and the limits of 10CFR20 as specified in T.S. 3/4.11.1. The dose calculations in the ODCM ensure these limits are not exceeded,
- b. UFSAR Section 15.7.2.1 describes rupture of the evaporator bottom tanks as the.most limiting fault in an accident-involving radioactive liquid waste system leak or failure. Also, the postulated radioactive release due to a liquid radwaste tank failure is limited by failure of an RWCU phase separator tank.
The evaporators are not currently used.in processing liquid radioactive waste, nor are they affected by these changes._ The proposed changes also do not alter the function or operation of the RWCU phase separator tanks, nor do they result in increased activity in the contents of the tank. Therefore, these changes will not increase the probability of occurrence of a tank rupture or failure. PHPC SAFETY EVALUATION - 1 C____._-______ _ . _ _ _ _ _ .

- c. The liquid radwaste system is not safety-related, nor does it perform any function required for performance of a safety system >
by safety related components, systems or structures. The proposed changes have no effect on the accidents analyzed in UFSAR section 15.7.2.1 and therefore will not increase the consequences of these i accidents.
- d. Implementation of the proposed changes will not create any new interface, or new failure mode which would affect any components, systems or structures which are safety related or important to safety.
- e. Implementation of the proposed changes will not create any new, or -
affect existing functions which mitigate the consequences of a malfunction of equipment important to safety previously evaluated in the UFSAR.
- f. Implementation of the proposed changes do not change any function, parameter or operating characteristics which would result in cre& tion of an interf ace with or affect upon safety r. elated components, systems or structures.
- g. No new interface with or affect upon equipment important to safety is created with these changes. Therefore, these-changes do not create the possibility of a malfunction of a different type than previously evaluated in the UFSAR.
- h. These changes do not change the limiting condition for operation, applicability, action or surveillance requirements as defined in the bases for Tech. Spec. 3/4.11.1-4 or 3/4.7.11.

i DNIRONMENTAL EVALIATICN FOR C/R 88-103 (a) Section 2.1, Aquatic Issues, of the Envimm.sdal Protection Plan (EPP) assigns the Mississippi Department of Natural Resources the responsibility for effluent limitations and monitoring. Therefore, provisicos are in place to control liquid discharges and a change to the EPP is not necessary. The Radiological Effluent Technical Specifications control radiological aspects of liquid and gamecus effhwnts. The EPP is limited to non-radiological matters. (b) Section 5.6.1 of the FES evaluates aquatic-ecology inpacts of liquid discharges described in Section 4.2 of the FES. No adverse envircmental impact was shown by this evaluation. (c) The quantity of liquid effluents frtzn radwaste will increase by approximately a factor of ten. Howver, liquid radwaste is a minor waste stream. Based on Discharge 2 nitoring Reports for 1987 (see attached), liquid radwaste averages only 0.35% of the total wasteenter average flow. Also, because af the treatment applied to liquid radwaste, suspended solids emcentration averages 1% of the allowable, or an average of 0.09 lbv day. Both the flow and TSS are insignificant when empared to tM total effluent. ' Therefore, no significant change in effluents will occur. 7his change is not in any way connected to plant power level. Therefore, no change will occur in power level. (d) Liquid effluents were leviewed and evaluated in Section 4.2 and 5.6 of the FES. Liquid radwaste was considered a minor portion of the station effluent.

Attachment to the Safety Evaluation for ODCM, Rev. 12 Summary of Changes: ODCM, Rev.12 revises ' ae gaseous setpoint calculation methodology which incorporates editorial changes to clarify the setpoint calculation. These minor changes have no effect on the setpoint calculation. There are three specific changes being made in ODCM, Rev. 12. These changes are summarhed below. It is important to note that none of the changes being made to the gaseous setpoint calculation methodology in Rev.12 of the ODCM will yield setpoints that are leo conservative than the current methodology in ODCM, Rev. 11.
- 1) A new allocation factor has been addeu and the safety factor has been revised for the setpoint calculation based on grab sample radionuclides concentrations. This change by itself will yield a more conservative setpoint than the current methodology.
- 2) The flexibility on setpoint affistment requirements has been increased to allow the existing setpoint to semain as long as the existing setpoint is no more than 25% higher than the newly calculated setpoint. This change by itself could potentially yield a setpoint that is slightly less conservative than the current methodology.
It should be noted that when the conservative effects of change 1) are combined with the less conservative effects of change 2) that the resulting setpoint from Rev.12 of the ODCM will be no less conservative than the current methodology. It should also be noted that change 2) will have no effect on the conservative setpoint method. This is be w the new conservative method will always yield a fixed setpoint for tw.h .onitor based on the fixed maximum designed ventilation flow rate of snat system and the fixed volume efficiency of the radiation monitor. Since the setpoint will not fluctuate when determined using the conservative method, the +25% allowance will not be used.
- 3) The conservative setpoint _ calculation method has been revised as follows:
a) The setpoint calculation based on the Kr-89 skin dose factors has been deleted because the setpoint calculation based on Kr-89 total body dose factors will always be more conservative. This change by itself has no effect on the setpoint calculation, because the setpoint will still be based on the Kr-89 total body dose factors as it always has been. b) The equations for R t" and C were combined to form one equation. l This change by itself has no effect on the setpoint calculation because all the terms of both equations either remain or were canceled.

c) A new allocation factor has been added and the safety factor ; revised. This change by itself wili yield a more conservative I setpoint than the current methodology, d) The volume efficiency of the detector system has been fixed at the volume efficiency determined during the primary calibration. The volume efficiency will be checked by the calibration procedure to ensure that it does not vary by more than i 25%. This change by itself could potentially yield a setpoint that is slightly less conservative than the current methodology. It should be noted that when the conservative effects of change-3c). are combined with the less conservative effects of change 3d) that j the resulting setpoint from Rev. 12 of the ODCM will be no less ' conservative than the current methodology.
