1.1 INTRODUCTION

The environmental impact of Grand Grand Nuclear Station (GGNS) construction and operational activities between January 1 and December 31, 1983, was measured by the Environmental Surveillance Program.

The results of the Environmental Surveillance Program contained in the following sections indicate the. environment has not been adversely impacted by GGNS.

Factual information about GGNS and its operation is provided in the remainder of this section.

Location GGNS is a nuclear power station owned by Middle South I'.

Energy, Inc. and South Mississippi Electric Power Association (SMEPA) and operated by Mississippi Power & Light Company (MP&L).

An area map showing the geographical location of the facility is provided in Figure 1-1.

GGNS is located in Claiborne County, Mississippi, on the east bank of the Mississippi River, approximately 25 miles south-southwest 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 1-1/2 miles to the north.

The town of Port Gibson L

is about 6 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 Mississippi River and average about 5 to 7 feet in depth.

GENERAL AREA MAP n--

Site and Its Environs The site and its environs consist primarily of woodlands

~

divided between two physiographic regions.

The western half of the site is in the alluvial plain of the Mississippi Rivers 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 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 2376 acres originally purchased by MP&L.

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. Army Corps of Engineer's shoreline modification program.

The present acreage figure for the site due to erosion is 2300 acres.

The site boundary is the same as the property line except in the southeast 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.

There are no railroads or waterways that traverse the site.

An unpaved county road runs through the site in the south-southeast, south, south-southwest, and southwest sectors.

This road provides access to Hamilton and Gin Lakes and the Mississippi River from the Port Gibson-Grand Gulf Road.

Access The site area is accessible by two major highways: U. S.

Highway 61 and State Highway 18, which connect Port Gibson (6 miles southeast of the site) with Natchez, Jackson and Vicksburg.

History of Operation and Present Status The Station consists of two Boiling Water Reactors (BWRs) rated at 1250 MWe each.

Unit I received a Low-Power Operating License on June 16, 1982.

Fuel loading began on July 1, 1982, and was completed on August 6, 1982.

Initial criticality was achieved on August 18, 1982.

Low-power testing began on September 25, 1983 and was discontinued on November 8, 1983, with 995.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> of operation at less than 5 percent power recorded for Unit 1.

Low-power testing resumed on April 22, 1984, and commercial operation is planned for late 1984.

The following list summarizes significant dates associated with the operation of Unit 1:

o Low-Power Operating License June 16, 1982 o

SECTION 2 ENVIRONMENTAL SURVEILLANCE ACTIVITIES 2-L 12RESlay

2.1 SMOKE CONTROL Open burning of waste materials at GGNS is not permitted.

Wastes are burned in a pit utilizing an air curtain incinerator destructor which blows air over the fire to insure complete combustion of ignitable material.

This process reduces particulate emissions to the environment.

Daily inspections of the' burn pit are made by Environmental Surveillance Program personnel.to insure compliance with the State of Mississippi's regulations on burning.

2.2 EROSION CONTROL Erosion control at GGNS is a major priority because of the proximity of GGNS to the Mississippi River, the hilly terrain, the average annual rainfall of approximately 50 inches and the loess soils which are extremely susceptible to erosion.

The methods utilized to control erosion are:

o Immediate revegetation of disturbed areas o

Utilization of concrete chutes and flumes which channel runoff into two sediment basins, A and B (Figure 2-1).

Sedimentation occurs in the basins which minimizes ecological effect on the two oxbow lakes (Hamilton and Gin) and the Mississippi River.

2.3 TRANSMISSION LINE SURVEYS There are four transmission lines associated with GGNS (Figure 2-2).

A 115 kV transmission line from Port Gibson, Mississippi, supplies construction power and emergency power to GGNS.

The Baxter Wilson and Franklin lines are 500 kV transmission lines which terminate in Warren and Franklin 2-1 12RESlay

.., u,

., nstit 2-3

1 counties respectively.

The fourth line, Ray Braswell, is a planned-500 kV transmission line which will connect GGNS to an existing 500_kV transmission line in Warren County.

A semiannual aerial survey of these lines is conducted to observe vegetation growth and to monitor for erosion.

When problem areas are identified, ground patrols are sent in to make a closer observation.

Recommendations are then made to the Mississippi Power & Light Company (MP&L) Engineering Department for corrective action.

These areas are closely monitored during follow-up serial surveys to determine the effectiveness of the corrective actions.

Techniques designed to minimize erosion are used to reclear and control vegetation on these transmission lines.

All highway, river and stream, and railroad crossings are hand cut, usually leaving buffer strips adjacent to the crossing.

The use of heavy equipment in clearing right-of-ways is limited to piling brush and pushing brush piles.

Potential erosion areas are seeded and mulched.

The long growing season in this area provides excellent early root formation which helps prevent damaging erosion.

Synthetic erosion prevention material is utilized when necessary.

2.4 CHEMICAL AND SOLID WASTE MANAGEMENT Liquid wastes such as chemicals, fuels, lubricants, bitumens and flushing solutions, are deposited or discharged into tanks for salvage or subsequent removal to appropriate off-site locations.

Adequate care is taken to avoid the handling or storing of liquids in close proximity of major drainage areas to avoid potentially damaging spills to site streams.

2-4 12RESlay

Construction scrap and debris are collected in designated on-site areas for salvage, incineration or burial.

Unuseable, combustible materials are incinerated onsite in an air curtain destructor burn pit.

Emission levels and operation of the burn pit incinerator is in accordance with Mississippi Air Quality Regulations.

Emissions and odors are kept at an acceptable minimum and all control devices are maintained in good working order.

Noncombustible solid wastes are buried at designated landfill areas on the site.

2.5 LAND MANAGEMENT AND WILDLIFE Approximately 2300 acres owned by MP&L makes 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, which is excellent habitat for Mississippi wildlife, is productively utilized, keeping wildlife enhancement in mind.

Several agricultural leases with local farmers have been established at GGNS.

Some lands have been leased to an area farmer for grazing purposes.

The farmer uses every available resource to have a productive operation while meeting the GGNS criteria for wildlife enhancement.

Other areas are leased for the production of hay and soybeans.

The hay fields serve as open areas and the soybeans attract wildlife year round.

2-5 12RESlay

Fringe areas and open fields are mowed a minimum of two times during each growing season.

This keeps open areas from being overtaken by scrub vegetation.

After the growing season, a series of small food plots are planted in these open fields to help sustain wildlife populations through the winter and early spring.

A small fruit orchard and garden are maintained on site by Environmental Surveillance Program personnel.

This provides fruit and vegetable samples necessary for the GGNS Radiological Environmental Surveillance Program broadleaf sampling requirements.

Two lakes located on the site, Gin and Hamilton, are used for sport and commercial fishing.

Operation of the station has had no apparent ecological effect on the fish population in these lakes.

Utilization of the lakes and surrounding local lands by water dependent species (waterfowl) is seasonal, with most activity occurring during the fall and winter migrations.

Hunting on the site is limited to bow hunting for deer by members of the MP&L Bow Hunting Club.

Other hunting activities are prohibited on the GGNS site.

2.6 GROUNDWATER MONITORING A groundwater monitoring program has been established at GGNS to:

o Provide data on the seasonal flunctuation of the regional groundwater table o

Define the cone of depression caused by plant pumping operations o

Monitor the level of the perched groundwater table in the Unit I and 2 Power Block areas.

2-6 12RESlay

= -. - _ _

Location of Monitoring Wells Twenty-seven wells are used to monitor the regional and perched groundwater underlying GGNS:

o 12 wells monitor the regional groundwater levels in the site area o

15 wells monitor the 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.

Regional Groundwater Wells used to monitor the regional groundwater levels (Figure 2-3 and Table 2-1) are measured twice a month.

Fluctuations in the regional groundwater table levels have indicated that maximum groundwater levels occur in June through August, with minimum levels occurring in November through January.

These seasonal fluctuations correspond to those of the Mississippi River.

No indications of groundwater depletion have occurred since the inception of the program.

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 wells (MW-1 through MW-7) monitor the water levels in the perched aquifer and eight wells are in place to dewater the aquifer if water levels approach or exceed 109 feet Mean Sea Level (MSL).

Water levels in perched aquifer wells are observed and recorded once per month.

semiannual basis to determine what effects, if any, will result from GGNS' heated discharge into the river.

The NPDES Permit states that "the receiving water shall not exceed a maximum water temperature change of 2.8'C 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 2-12 12RESlay

downstream from the point of discharge as measured at a depth of five feet."

To initiate the thermal monitoring program and obtain baseline data, the river bank was surveyed to establish and permanently mark 72 reference points 100 feet apart.

Sixty-six of the reference points are located downstream of the Station's discharge into the river, and the remaining 6 are located upstream of the discharge.

Calibrated digital thermometers are used to obtain temperatures at a depth of 5 feet and at the surface.

At each reference point, measurements are taken 100 feet from the river bank, then at 10 feet intervals until reaching the bank.

This provides 20 temperature data points for each reference point.

2.9 COOLING TOWER DRIFT PROGRAM The Environmental Protection Plan requires that a study be conducted to determine the environmental effects of salt deposition from cooling tower drift.

MP&L 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.

The study utilizes seven fallout collection buckets located four to five feet above the ground, fitted with bird rings, and covered with fine mesh screens te exclude insects and leaves.

2-13 12RESlay

Salt Deposition Station Locations Six of the seven Salt Deposition Stations (SDS) are located in areas where maximum salt deposition is predicted.

These areas were extrapolated from a Salt Deposition Model developed for MP&L.

Two of the stations (Stations 2 and 5) have two replicate sampling devices, with one of the replicates at each location being a dry collector (Stations 2b and 5b).

The seventh station is a control located south of Raymond, Mississippi.

The location of the SDS sites are identified in Figures 2-5 and 2-6 and listed in Table 2-3.

Sample Analysis and Collection Samples are 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 parameters were selected because past analyses have shown them to be prevalent in the Plant Service Water system.

Salt constituents are determined for the demineralized water used in the initial setup of the collection buckets.

Rainfall data is recorded for each sampling site.

Screens are washed with deionized water and the wash water volume is measured and deposited in the collector on a quarterly basis.

The volume of water in the collector is then measured, and a composite sample of the collector's contents is placed in a clean cubitainer, sealed and labeled with the date of removal, 2-14 12RESlay

2.10 METEOROLOGICAL SYSTEM The GGNS meteorological tower with base elevation of 160 feet above MSL is approximately 5,000 feet northwest of the GGNS Unit I reactor building, which has a finished grade 132 feet above MSL.

The location of the meteorological tower is shown in Figure 2-7.

The area around the tower is flat and grass covered.

The nearest bluffs are 362 feet to the west of the tower with trees 35 feet high along the bluffs.

Approximately 400 feet to the east are trees 50 to 60 feet high along with a hill about 30 feet higher than the base of the tower.

To the south, the nearest trees 50 to 60 feet high are 690 feet from the tower.

A county road passes the meteorological tower 400 feet to the north.

The tallest structure, the GGNS Unit 1 natural draft cooling tower, is 522 feet high and is situated approximately 5,750 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 any airborne material will be released from the plant.

The following parameters are monitored at the 133 and 33 feet levels of the tower:

o Wind Direction o

Wind Speed o

Temperature o

Change in Temperature ( A T) o Dew Point l

The data for the Meteorological Program is included in the Semiannual Effluent Release Reports submitted to the U. S. Nuclear Regulatory Commission. 2.11 ENVIRONMENTAL EVALUATIONS The Environmental Protection Plan (EPP) for GGNS permits changes in station 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. Grand Gulf Nuclear Station personnel review changes in plant design or operation and the performance of tests and experiments for the possible effects they might have on the environment. When the review determines that the change test or experiment may affect the environment, an Environmental Evaluation is prepared and recorded by Radiological & Environmental Services staff before additional construction or operational activities associated with the change, test or experiment are begun. However, the EPP excludes changes, tests or experiments from the evaluation: o If all measureable environmental effects are confined to onsite areas previously disturbed during site preparation and plant construction, or 2-21 12RESlay

If they are required to achieve compliance with other o Federal, state, or local requirements. Review of changes, tests and experiments at GGNS is conducted by one of three groups: o Nuclear Plant Engineering o GGNS Plant Staff o Radiological & Environmental Services (R&ES) All three groups perform an applicability determination of proposed changes, test or experiments to ascertain if the activity might affect the environment. Only those which have the potential to affect the environment receive Environmental Evaluations. Since R&ES controls the EPP, it is their responsibility to perform Environmental Evaluations. Nuclear Plant Engineering has the authority to perform Environmental Evaluations, but R&ES have final responsibility to provide concurrence once the evaluation is completed. 2-22 12RESlay

SECTION 3 OBSERVATIONS AND DISCUSSION 3-1 12RESlay

3.1 SMOKE CONTROL-Daily inspections of the burn pit were conducted by Environmental Surveillance Program personnel in 1983. During the, year 18 opacity violations were noted. Timely corrections were made on each occasion. No other smoke control problems were identified during 1983. The operation and construction of GGNS has contributed insignificant smoke emissions to the environment surrounding GGNS. 3.2 EROSION CONTROL During 1983 73.94 inches of rainfall were recorded at GGNS. Runoff samples were taken during periods of heavy rainfall at the influent and effluent of each basin to determine the sediment load and the efficiency of each basin. The results, reported in Table 3-1, indicate an overall reduction in sediment loading coming into the Basins. This may be attributed to the stabilization and revegetation of the majority of disturbed areas on site. 3.3 TRANSMISSION LINE SURVEYS (1983) The semiannual aerial surveys of the GGNS transmission lines identified no major problem areas during 1983. Reclearing was completed on the Franklin Line with the exception of a swampy area near the Homochitto River. No additional reclearing was done on any other GGNS lines. Some minor erosion was identified on the southern end of the Baxter Wilson Line. A ground survey will determine the extent of the erosion and corrective action will be taken. 3-1 12RESlay

Minor erosion due to off-road travel by area hunters was evident on the southern end of the Franklin lina. These areas are being monitored closely. No herbicides were used in controlling vegetation on GGNS transmission lines during 1983. 3.4 CHEMICAL AND SOLID WASTE MANAGEMENT 3.4.1 Solid Waste Solid waste generated at GGNS during 1983 did not present any unanticipated problems or adversely affect the environment. Office waste, rubble and debris were incinerated or buried onsite without incident. Solid waste activities at GGNS in 1983 were in compliance with Mississippi Department of Natural Resource, Bureau of Pollution Control, " Solid Wastes Disposal Law of 1974." 3.4.2 Chemical Waste Nonhazardous Waste GGNS did not incur any serious problems or incidents with chemical waste control in 1983. Chemicals of a nonhazardous nature (resins, silica gel, charcoal) were successfully disposed of onsite. Chemicals which were suitable for re-use were recycled through local contractors and nonprofit organizations. Other nonhazardous chemicals (borate water, phosphates) were discharged through National Pollutant Discharge Elimination System outfalls and reported accordingly. 3-3 12RfSlay

A few items concerning chemical waste control in 1983 are identified below: o A minor chemical spill (200 gallons) occurred on January 30, 1983 when a flange leaked on the Betz 2020 tank. The spilled material was cleaned up with no apparent environmental damage, o On April 7, following a heavy rainfall, a small oil sheen was noted at the head of Sediment Basin B. Since the amount observed was small, no action was taken. The probable cause of the sheen was determined to be site runoff. o The Mississippi Department of Natural Resources granted MP&L permission in May, 1983, to dispose of 84 fifty-five gallon drums of nonhazardous wastes through the oil / water separator at NPDES Outfall 008. Monitoring of the discharge was conducted, with no adverse environmental impact

observed, o

A lube oil spill occurred in September following the Diesel Generator fire. The lube oil was contained in Sediment Basin "B" with no oil evident below the dam. No ecological damage occurred from this spill. o Less than five gallons of-50% NaOH was spilled in October. The spill was quickly contained and neutralized with NaHC0. No adverse environmental 3 effects were evident. Hazardous Waste Hazardous wastes or chemicals (acids, sealants) were collected and stored in GGNS' Hazardous Waste Storage Area. The Department of Natural Resources inspected the Hazardous Waste Storage Area and related activities in 1983. They found the storage area and GGNS generally in compliance with the Interim Status Standards of the Resource Conservation and Recovery Act (RCRA). GGNS prepared its Part B Hazardous Waste Permit Application in 1983 and expects to receive a 3-4 12RESlay

4 } permit before the end of 1984. Copies of GGNS' Generator and Facility Annual Hazardous Waste Reports are included in Appendix 1. Polychlorinated Biphenyls (PCBs) Sampling of dielectric fluid for PCBs was completed in 1983. Dielectric fluid units contaminated with PCBs have been properly marked and identified. No known releases or exposures related to PCBs occurred in 1983. 3.5 LAND MANAGEMENT AND WILDLIFE Two endangered species, the American alligator (Alligator mississippiensis), and the Bald Eagle (Haliaetus 1. leucocephalus), were both reportedly observed on or near GGNS property during 1983. Alligators are known to inhabit both Hamilton and Gin Lakes and their tributaries. The eagles were reportedly observed during the unseasonably cold December weather. During the 1983 bow hunting season (October, 1982-February, 1983) 15 deer were killed. There were 124.6 hunting hours per deer killed for a hunter success ratio of 2.9% for the season. The operation of the station has had no apparent ecological effect on the wildlife population or vegetation in the GGNS , vicinity. 3.6 GROUNDWATER Regional Groundwater Regional groundwater monitoring data is presented in Table 3-2. Water levels occurred at expected elevations. Fluctuations in well water elevations were attributed to flooding of the 3-5 12RESlay

4 e' Mississippi River. The 1983 data was consistent with preoperational and 1982 data. Perched Aquifer Perched groundwater data is presented in Table 3-3. A hydrograph for each perched aquifer well is provided in Appendix II. Unusually heavy rainfall during the fall of 1982 and spring c of 1983 caused the water level in the perched aquifer to rise. From January through August 1983, dewatering well DW-8 slightly exceeded the design basis groundwater elevation for GGNS of 109.00 feet above MSL. No safety-related equipment was affected by this temporary increase above the design basis groundwater elevation. The details and a prescribed course of action involving this event are outlined below: The power block area and Standby Service Water (SSW) L-basins for GGNS-Units 1 and 2 were constructed within an .open excavation that extends from yard grade at elevation 132.5 feet above MSLito the Catahoula Formation at approximately 87 feet above MSL. Seepage of groundwater and rainfall into the excavation area from the terrace deposits overlying the Catahoula Formation was initially controlled by pumping water from sumps. However, as construction proceeded, these sumps were replaced with a Construction Monitoring and Dewatering System to continue the removal of seepage from the excavation area and to monitor water levels in the perched aquifer. 3-7 12RESlay

This Construction Monitoring and Dewatering System at GGNS consists of eight dewatering wells and seven monitoring wells. The dewatering wells are 10 inches in diameter and are located around the power block of Units 1 and 2. Four wells (DW1-4) are located on the Unit 2 side of the power block, three wells (DW6-8) are on the Unit 1 side area and one well (DW-5) is located adjacent to the SSW basins which are common to both areas. The Units 1 and 2 dewatering wells are located in the excavated area between the tie-back wall and station structures as shown in Figure 2-4. This area has been refilled and covered with a clay seal in the case of Unit 1, but it is still open on the Unit 2 side. The Unit 1 dewatering wells and SSW basin well have not been operated since the completion and turnover of Unit 1 to MP&L in April, 1982. The Unit 2 wells are still operational. The seven monitoring wells (MW-1 through MW-7) are composed of 6-inch diameter PVC pipe installed within the backfill. Their locations are also identified in Figure 2-4. Water levels in these dewatering and monitoring wells have been measured at least monthly since their installation in 1976, with the exception of the. periods from April 4 to September 24, 1982 and November 19, 1982 to January 28, 1983. During these periods, only the Unit 2 wells were measured. This monthly monitoring program has indicated that for the period of January 28, 1983 through August 24, 3-9 12RESlay

~ 1983 the. design maximum groundwater elevation of 109.0 feet above MSL was exceeded in the vicinity of dewatering well DW-8. The primary cause of this high groundwater elevation was attributed to the unusually heavy precipitation which occurred in the area from December, 1982 through June, 1983 (Table 3-4). Precipitation measurements recorded by GGNS's meteorological system indicated that 69.81 inches of rainfall fell on the area during these months. This is 200 percent above the long-term mean rainfall for this time of year as determined by the National Weather Service in Jackson, Mississippi. The values in Table 3-3 reflect how the perched aquifer responded to this increase in rainfall. An increase of 4 to 5 feet in water levels measured in wells on the Unit 1 side of the power block was common during this time period. With two exceptions the rise in water levels was not reflected in a concurrent rise in Unit 2 observation well water levels. This is because levels in the Unit 2 area were controlled by operation of the Unit 2 dewatering wells in response to rising water levels. The two exceptions were DW-1 and MW-7 which are located adjacent to each other on the east side of Unit 2. Due to operational problems with the pump in DW-1 which serves this area, it operated only intermittently from February through June, 1983, resulting in an increase in water level for both DW-1 and MW-7. 3-10 12RESlay

4 a l~ The GGNS Architect / Engineer is studying this problem to determine the cause of the event and a possible solution. The 'information derived from this study and a potential course of action is expected to be identified by January 1, 1985. As an~ interim measure the Unit 1 dewatering wells will be reactivated to preclude recurrence of this event. 4 ' 3.7' NPDES d The 1983 results for all permitted outfalls were reported in the NPDES Quarterly Reports. The Mississippi Department of Natural Resources and the U. S. Nuclear Regulatory Commission received copies of these reports. Several items noted during 1983 and included in the quarterly reports are summarized below: o The Plant Service Water System (PSW) was shut down for the majority of January; therefore, temperature information for .0utfall 001 was not available during that time. o A violation of the NPDES Permit occurred for Outfalls 004 and 005 in January, when the Standby Service Water Basins discharged measureable amounts of chlorine for greater than-120 minutes. Actions were taken to preclude a recurrence of this violation. o A discharge;of Outfall 006 (Low Volume Waste Basin) occurred in January without an oil and grease sample being analyzed by the approved U. S. Environmental Protection Agency (EPA) method. However, a sample of the discharge which was viewed under an ultraviolet light indicated no visible oil sheen. o Permission was received from Mr. Larry Hamil of the Mississippi Department of Natural Resources to sample Outfalls 007, 008 and 009 at a confluent location. This was ' initiated in January 1983, with the results reported on the Discharge Monitoring Report for Outfall 007. 1 1 3-12 12RESlay

y-- o Approximately 400 gallons of water /demineralizer resins (Ecodex) mixture was inadvertently emptied into the storm drain at Outfall 009 on June 8, 1983. A sample was collected at the confluence of Outfalls 007, 008, and 009 and analyzed for total suspended solids and for oil and grease. o Outfall 001 was shut down for maintenance from June 20 to June 23, 1983. o Outfall 002 discharged 11,000,000 gallons of water from April 26 to May 10, 1983. The discharge was continuous and had no detectable residual chlorine. o A discharge of Outfall 006 occurred in May without being analyzed for oil and grease by the approved U. S. EPA method. However, a sample of the discharge, when viewed under an ultraviolet light, indicated no visible oil sheen. o The flow gauge installed at the confluence of Outfalls 007, 008 and 009 was washed away in May, 1983 as a result of a series of heavy rainfalls. The gauge design was modified and a new gauge was installed on July 7, 1983. o.In April and May, 1983, the cooling water for a diesel generator was discharged into Outfall 007 on three occasions. Samples were collected at the Outfall of Basin B and analyzed for nitrites; no detectable nitrites were determined to exist. In May, permission was received from Mr. Larry Hamil of the . o Mississippi Department of Natural Resources to empty.84 drums of non-hazardous waste into the oil / water separator at Outfall 008. Samples were collected and analyzed prior to discharge, o Outfall 004 overflowed August 8, 1983, due to an incorrect valve alignment. Approximately 6000 gallons of water overflowed onto the ground. Samples were collected and analyzed for NPDES parameters. On September 4, 1983 a fire in the Diesel Generator Building o caused oil to be released through Outfall 007. The oil was contained in Basin B and samples were taken and analyzed for oil and grease, Water was discharged from Outfall 006 on September 10, 1983 o without being analyzed for oil and grease by an approved U. S. EPA method. However, samples that were taken showed no visible oil and grease when viewed under an ultra-violet light. Sampling is now being conducted on a weekly basis rather than a discharge basis to assure compliance with the NPDES Permit. 3-13 12RESlay j

w o An incorrect valve alignment resulted in the discharge of approximately 100 gallons of diesel fuel through the confluence of Outfalls 007, 008 and 009 on September 16, 1983. o Standby Service Water Basin B (Outfall 005) overflowed on ~ December 1, 1983 when site power was lost. 87,000. gallons + flowed into a storm drain and then into Sediment Basin A (Outfall 013). o Approximately 6 million gallons of cooling tower water was released into Sediment Basin B (Outfall 014) on November 13-14, 1983. An additional 5 million gallons of cooling tower water was released via Outfall 001 on November 13-14, 1983. The flow rate for the quarterly report for Outta11 001 was adjusted to include the 6 million gallon release on November 13-14, 1983. Higher than normal total suspended solids occurred on i o November 23, 1983 at Outfalls 007, 008 and 009. This was due in part to heavy rainfalls preceding the sample collection. 3.8 THERMAL MONITORING Environmental Surveillance Program personnel performed monitoring to determine baseline winter thermal conditions on -February 17, 1983 and baseline summer thermal conditions July 26-28, 1983.. Thirteen of 72 points (51-64) were underwater during the winter monitoring -therefore, no data was available' for those points.- All 72 points were monitored during the summer. The results were organized.and plotted so that temperature changes could be noted at specific distances from the river bank at all accessible reference points. Additional information such as river flow, ambient temperatures and effluent temperatures were also recorded. The baseline data indicates that the turbulence of the river mixes the water such that only a small variation in temperature occurs between the surface and a depth of five feet.

The results will be reported to the Mississippi Department of Natural Resources as required by the NPDES Permit. 13.9 COOLING TOWER DRIFT Table 3-5 gives the calculated Salt Deposition Rates (SDR) .for all seven monitoring stations in the GGNS Cooling Tower Drift Program. Table 3-6 presents the cooling tower drift rainfall data. Statistical Development Presently, the data base is not yet extensive so the validity of some of the data could'be questioned. This is F especially true for the October-through-December, 1983 sampling period as can be seen by examining the total dissolved solids rates in Table 3-5. Nevertheless, data analysis is possible to obtain . quantitative estimates of the precision of the data and the relative importance of the various factors which can potentially influence salt deposition rates. The former can be quantified by .. estimating confidence limits for the various datas the latter by statistically analyzing the data by Analysis of Variance (ANOVA). The present statistical analysis uses a two-factor ANOVA which 3-15 12RESlay

3 involves calculating F-factors and conducting significance tests for the major potential influences (period, location and the interaction of the two). Statistical Model The basic statistical model selected for the analysis here is as follows: u+Pg+L3 + PLg3 + e (ij ) Dijk = k Where Dijk = basic SDR (Salt Deposition Rate) data u= mean SDR contribution due to sampling period P = g contribution due to sampling location L = 3 g3 = contribution due to sampling period and location PL interactions e (ij ) err r due to sampling, analytical, etc. techniques = k and other, unaccounted for, factors Interactions and " experimental" error can be separated in a multiple-factors experiments only if multiple observations are taken at various combinations of sampling periods and sampler locations. Determining confidence limits for the basic SDR data 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. Also, the " wet" (2, 2A, 5 and 5A) and " dry" (2B and 5B) sampler results will be pooled in the model as providing comparable estimates. For simplicity's sake a complete balanced 3-21 12RESlay

block design will be considered; that is, 3 replicate SDR's for each combination of periods.(four) and locations (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. Pseudo-data points have been estimated to complete the data block by minimization of the error sum-of-squares for the model; this is generally a good approximation for a data block with only a small number of missing data points. Table 3-5, giving the SDR data, include these pseudo-data points. Analysis of Variance (ANOVA) A computer program for the two-factor analysis of variance (ANOVA) of the data according to the described model has been developed. Basically, the progran calculates the sum-of-squares for each of the factors of interest (period, location, period-location interaction, and error). 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; of course, using standard student - t and F distribution tables, other levels of significance are readily determinable, if required. Table 3-7 summarizes the results of f this analysis. 3-22 12RESlay

As noted earlier,-it is necessary to use replicate salt deposition rates to separate " experimental error" (error between the replicates) from interaction influences. The use of composition in ANOVA instead of salt deposition rates may aid in this process as well as provide additional information regarding potential sourcec of the salt. Composition for an individual parameter (e.g. for sodium, for location 2, period 1, and replicate 1) is determined by dividing the valme of the salt deposition rate for the parameter by the sum of the corresponding values for all other constituents other than TDS. A two-factor ANOVA with 3 replicates is then conducted for 2 locations (f2 and

  1. 5) and 4 periods.

Table 3-8 provides a summary of the ANOVA based on composition. Results of the ANOVA (Table 3-7) for sampler locations 2 and 5 (with replicate samples) indicate that the interaction between sampler location and sampling period is not significant for all parameters other than sulfates and phosphates. Therefore, the two-factor ANOVA (without replicates) can be performed for the other parameters. Table 3-9 shows salt deposition data (5 locations, 4 periods) for sodium, iron, calcium, fluoride, chloride, magnesium, and total dissolved solids (TDS) for the ANOVA analyses without interaction. A computer program (similar to the previous program for ANOVA) calculates the F-Factors. Table 3-10 summarizes the results of the simplified ANOVA. t To analyze impacts of environmental factors such as rainfall, wind speed, prevailing wind direction and resultant 3-24 12RESlay

wind direction, 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) For each of the four sampling periods, data for rainfall and the frequency distributions for wind speed and direction have been obtained by reduction of GGNS weather data. Table 3-11 summarizes these four environmental factors. 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 f2 and #5 were used for the regression analyses. Table 3-12 gives the correlation coefficients (for each SDR parameter with each environmental factor) as obtained from the regression analyses. Conclusions o Data for total dissolved solids for all but two sampler locations for the fourth quarter are suspect because salt deposition rates (based on TDS) are zero. o Results of ANOVA (Table 3-7) based on salt deposition rates indicate the following: Interaction between sampler location and sampling period has no significant influence for all SDR parameters other than sulfates and phosphates. Sampling period has significant influence on all SDR parameters except for iron and fluoride. 3-29 12RESlay

Sampler location has significant influence only on fluorides, sulfates, and TDS. Sodium (+/-23%), Calcium (+/-28%) and Sulfate (i27.6%) data are relatively precise, while Iron (+/-103%), Fluoride ( /-265%) and Phosphate (+/-92%) data are relatively imprecise. If sources of depositing salt were the same and variations o in SDR were only due to sampler location, period and their mutual interaction, then ANOVA based on composition would be expected to show no dependence on the three factors. For sodium, calcium, and sulfates, at least five fold reductions in F-factors for location and period are apparent, indicating less dependence on the two factors. However, no clear trend has been established. Therefore, different sources of salt affect samplers at different locations differently for each period. (Please see Table 3-8). o Results of ANOVA (Table 3-10), assuming no interaction and without replicate samples, show similar trends for the influence of sampling period on SDR as previously with replicates, but show no clear trends for sampling location, o Results of regression analyses (Table 3-12) demonstrate the following: As expected, SDR tends to decrease with increasing rainfall during a sampling period. Sodium and calcium exhibit the most significant correlation coefficients with rainfall (-0.71 and -0.7 respectively). Correlation coefficients for both calcium and sulfate SDR's versus average wind speed are 0.72. Both parameters also show significant correlation coefficients for prevailing wind direction and resultant during the sampling periods. The above results may be interpreted as indicating the existence of a significant, general source of sodium salts (particularly sulfate and chloride) as well as a specific source of calcium sulfate (most probably) which are impacting the salt deposition samplers. Inspection of the site wind data indicates that the specific source is probably located to the north or northwest of the GGNS. Future Considerations The TDS data from the fourth sample collection period will o probably be discarded if used for any future data analyses. 3-32 12RESlay

o A qualitative, semi-quantitative or quantitative phenomenological model describing salt deposition in a general sense may be developed to utilize the monitoring . program's data appropriately. Which of the 3 levels of a model developed will depend on the uses to which the -analytical results will be put, the-precision and sensitivity required in assessing impacts. o As more data becomes available on SDR's, regression analysis will be considered using the data for individual locations. Also, regression analyses for multiple factors may be carried outs these can be useful in relating the various parameters as are ANOVAs. o To obtain better quantification of random sampling / experimental errors, the number of replicate samples obtained may be increased. o Covariance analyses may also be valuable for some SDR data to determine the effect of different variables at different locations. o If interrelationships between various constituents become important (e.g., for ascertaining whether sources are providing particular salts as opposed to separate ionic constituents), a generalized 3-factor block design may be formulated for ANOVA. Along with a phenominological model, this would provide a means by which impacts due to plant operations could be estimated more precisely. 3.10 METEOROLOGICAL DATA Meteorological Data for the 1983 reporting period was included in the Semiannual Effluent Release Reports submitted via AECM-83/0513 and AECM-84/0150 to the U.

4'.1 REPORTABLE INCIDENTS There were no reportable incidents observed during the reporting period. 4.2 NONREPORTABLE INCIDENTS Several minor events which occurred during the reporting period are outlined below: On March 2, 1983 a fish kill was reported in Basin A. An o investigation upstream and downstream of Basin A did not reveal any dead or dying fish. Water analyses of the basin revealed a pH of 8.3 and dissolved oxygen (D.O.) of 4.1 mg/1. Analyses were also performed on the water below the dam: pH - 8.2, D.0 - 3.6 mg/1. Visual examinations of the basin and its influent and effluent points were conducted through March 7, 1983. Mississippi Power & Light Company and the Mississippi Bureau of Pollution Control concurred that an algal bloom associated with abnormally warm temperatures could have been responsible for the fish kill. o On March 22, 1983 foaming was observed in Basin B where composite Outfalls 007, 008 and 009 enter the basin. No incident of foaming was observed in the discharge pipe. Nitrate analyses results were within allowable levels. o A volume of 110,000 gallons of water drained from Standby Service Water (SSW) Basin A to SSW Basin B when a drain valve was inadvertently left open on March 30, 1983. No adverse effects were realized. On June 2, 1983 a barge carrying drums of oil split when it o hit a support on the Mississippi River Bridge at Vicksburg. This resulted in a massive oil spill in the Mississippi River. Environmental Surveillance Program personnel surveyed the area around the plant including Gin and Hamilton Lakes and the Heavy Haul Road area on June 3, 1983. No signs of any oil were noticed in the lakes. This was probably due to the swif t river current which kept the oil in the main river channel. Arrangements were made by government agencies to collect the oil down river. 4-1 12RESlay

o 'On July 26, 1983, foaming was observed in the barge slip. A boom was placed at the confluent of the barge slip and the Mississippi River. The foaming was caused by trisodium phosphate (TSP) used in GGNS laundry facilities. The use of TSP has been replaced with a Department of Natural Resources-approved low phosphate, biodegradable detergent. o. On August 7, 1983 Standby Service Water (SSW) Basin B overflowed. An estimated 6000 gallons of water was discharged through an unpermitted outfall. The Mississippi Department of Natural Resources was notified of the discharge. Measures were taken to prevent a recurrence. o On September 4, 1983 a fire occurred in the Division I diesel generator, causing oil to leak into Outfall 007. This resulted in oil being discharged into Sediment Basin B. Two booms had been previously placed in the basin. The first boom contained 90% of the oil. The remainder of the oil was contained by the second boom. Analyses of the basin's effluent indicated no levels of oil and grease above allowable limits. No oil was present at the county crossroad ditch, the barge slip or the river. The cleanup operation was completed on September 5, 1983 and new booms .were deployed as a precaution. o On September 16, 1983 a valve misalignment caused 100 gallons of No. 2 diesel fuel to be discharged into the storm drain, resulting in an oil spill into Sediment Basin B. All of the oil was contained by the first boom. Analyses of the basin's effluent indicated no levels of oil and grease above allowable limits. The cleanup operation was completed the same day and new booms were deployed, o On September 29, 1983 a blown pump seal at Radial Well No. 1 resulted in the spill of about one gallon of oil through the french drain into the river. Cleanup operations were concluded on September 30, 1983. o On October 18, 1983 approximately five gallons of 50% sodium hydroxide was spilled or the ground at the south end of the Water Treatment Building. Neutralization and cleanup of the spill were completed the same day. o The Unit 1 Cooling Tower was drained through an unpermitted outfall beginning on November 13, 1983. The Mississippi Department of Natural Resources was notified of this violation on November 16, 1983. Operations personnel were instructed to discontinue this practice. 4-2 12RESlew
