Non-Radiological Environmental Programs

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report Non-Radiological Environmental Programs Meteorological Monitoring The Meteorological Monitoring Program at Davis-Besse is required by the Nuclear Regulatory Commission (NRC) as part of the program for evaluating the effects of routine operation of nu clear power stations on the surrounding environment. Both NRC regulations and the Davis Besse Technical Requirements Manual provide guidelines for the Meteorological Monitoring Program. These guidelines ensure that Davis-Besse has the proper equipment, in good working order, to support the many programs utilizing meteorological data.

Meteorological observations at Davis-Besse began in October 1968. The Meteorological Moni toring Program at Davis-Besse has an extensive record of data with which to perform clima tological studies which are used to determine whether Davis-Besse has had any impact upon the local climate. After extensive statistical comparative research the meteorological personnel have found no impact upon local climate or short-term weather patterns.

The Meteorological Monitoring Program also provides data that can be used by many other groups and programs: Radiological Environmental Monitoring Program, The Emergency Prepar edness Program, The Chemistry Unit, and groups such as Plant Operations, Plant Security, Mate rials Management, Industrial Safety Program, plant personnel and members of the surrounding community.

The Radiological Environmental Monitoring Program uses meteorological data to aid in evalu ating the radiological impact, if any, of radioactivity released in Station effluents. The meteoro logical data is used to evaluate radiological environmental monitoring sites to assure the program is as current as possible. The Emergency Preparedness Program uses meteorological data to cal culate emergency dose scenarios for emergency drills and exercises and uses weather data to plan evacuations or station isolation during adverse weather. The Chemistry Unit uses meteorological data for chemical spill response activities, marsh management studies, and wastewater outfall flow calculations. Plant Operations uses meteorological data for cooling tower efficiency calcu lations, forebay water level availability and plant work which needs certain environmental con ditions to be met before work begins. Plant Security utilizes weather data in their routine plan ning and activities. Materials Management plans certain plant shipments around adverse weather conditions to avoid high winds and precipitation, which would cause delays in material deliveries and safety concerns. Industrial Safety uses weather and climatological data to advise personnel of unsafe working conditions due to environmental conditions, providing a safer place to work.

Legal Affairs uses climatological data for their investigation into adverse weather accidents to the plant and personnel.

Davis-Besse Nuclear Power Station 2000. Annual Radiological Environmental Operating Report On-site Meteorological Monitoring

System Description

At Davis-Besse there are two meteorological systems, a primary and a backup. They are both housed in separate environmentally controlled buildings with independent power supplies. Both primary and backup systems have been analyzed to be "statistically identical" to the other so if one system fails the other can take its place. The instrumentation of each system follows:

PRIMARY BACKUP 100 Meter Wind Speed 100 Meter Wind Speed 75 Meter Wind Speed 75 Meter Wind Speed 10 Meter Wind Speed 10 Meter Wind Speed 100 Meter Wind Direction 100 Meter Wind Direction 75 Meter Wind Direction 75 Meter Wind Direction 10 Meter Wind Direction 10 Meter Wind Direction 100 Meter Delta Temperature 100 Meter Delta Temperature 75 Meter Delta Temperature 75 Meter Delta Temperature 10 Meter Ambient Temperature 10 Meter Ambient Temperature 10 Meter Dew Point 10 Meter Solar Insolation Precipitation Meteorological Instrumentation The meteorological system consists of one monitoring site located at an elevation of 577 feet above mean sea level (IGLD 1955)*, a 100m free-standing tower located about 3,000 feet SSW of the cooling tower, and an auxiliary 10m foot tower located 100 feet west of the 100 m tower, are used to gather the meteorological data. The 100m tower has primary and backup instruments for wind speed and wind direction at 100m and 75m. The 100m tower also measures differential temperature (delta Ts): 100-10m and 75-10m. The 10m tower has instruments for wind speed and wind direction. Precipitation is measured by a tipping bucket rain gauge located near the base of the 10m tower.

According to the Davis-Besse Nuclear Power Station Technical Requirements Manual, a mini mum of five instruments are required to be operable at the two lower levels (75m and 10m) to measure temperature, wind speed, and wind direction. During 2000, annual data recoveries for all required instruments were 99.76 percent. Minor losses of data occurred during routine in strument maintenance, calibration, and data validation.

Personnel at Davis-Besse inspect the meteorological site and instrumentation regularly. Data is reviewed daily to ensure that all communication pathways, data availability and data reliability are working as required. Tower instrumentation maintenance and semiannual calibrations are performed by in-house facilities and by an outside consulting firm. These instruments are wind tunnel tested to assure compliance with applicable regulations and plant specifications.

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report Meteorological Data Handling and Reduction Each meteorological system, primary and backup, have two Campbell Scientific Dataloggers (model 21XL) assigned to them. The primary system has a first datalogger to communicate 900 second averages to the control room via a Digital Alpha computer system. This is a dedicated line. If a failure occurs at any point between the primary meteorological system and the control room the control room can utilize the second data logger in the primary shelter. Each datalogger has its own dedicated communication link with battery backup. The backup meteorological sys tem is designed the same as the primary; so to lose all meteorological data the primary and backup meteorological systems would have to lose all four dataloggers. However, this would be difficult since each is powered by a different power supply and equipped with lightning and surge protection, plus four independent communication lines and datalogger battery backup.

The data from the primary and backup meteorological systems are stored in a 30-day circular storage module with permanent storage held by the Digital Alpha computer. Data goes back to 1988 in this format and to 1968 in both digital and hardcopy formats. All data points are scruti nized every 900 seconds by meteorological statistics programs running continuously. These are then reviewed by meteorological personnel daily for validity based on actual weather conditions.

A monthly review is performed using 21 NRC computer codes, which statistically analyze all data points for their availability and validity. If questionable data on the primary system can not be corroborated by the backup system, the data in question is eliminated and not incorporated into the final database. All validated data is then documented and stored on hard copy and in digital format for a permanent record of meteorological conditions.

Joint Frequency Distributions and Wind Sector Graphics Summary statistics and Joint Frequency Distributions (JFDs) of wind and stability data are gen erated and the results are reviewed for consistency in terms of known site characteristic and re gional climate. The end result of the review process is a validated final database suitable for use by atmospheric dispersion models and for site meteorological characterizations. Wind Sector Graphics represent the frequency of wind direction by sector and the wind speed in MPH by sector. This data is used by the NRC to better understand local wind patterns as they relate to defined past climatological wind patterns as reported in Davis-Besse's "Updated Safety Analysis Report."

Meteorological Data Summaries This section presents summaries of the meteorological data collected from the on-site monitoring program at Davis-Besse during 2000. Tables 28 through 30, discussed in this section, can be found on pages 120 through 139.

Wind Speed and Wind Direction The maximum measured sustained wind speeds for 2000 were 46.69 mph for the 100m level on December 12, 44.32 mph for the 75m level on December 12, and 32.04 mph for the 1Oin level on Decemberl7. Figures 32-34 give an annual sector graphic of average wind speed and percent frequency by direction measured at the three monitoring levels. Each wind sector graphic has two radial bars.

117

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report The darker bar represents the percent of time the wind blew from that direction. The hatched bar represents the average speed of the wind from that direction. Wind direction sectors are classi fied using Pasquill Stabilities. Calms (less than or equal to 1.0 mph) are shown in percent in the middle of the wind sector graphic.

Ambient and Differential Temperatures Monthly average, minimum and maximum ambient temperatures for 2000 are given in Table 29.

These data are measured at the 10m level; with differential temperatures taken from 100m and 0

75m levels. The yearly average ambient temperature for 2000 was 50.57 F. The maximum temperature was 89.15'F on June 10 with the minimum temperature of -4.78°F on January 22.

Yearly average differential temperatures were -0.25'F (100m), and -0.12'F (75m). Maximum differential temperatures for 100m and 75m levels were 7.99°F on December 9, (100m), and 7.99°F on December 9, (75m). Minimum differential temperatures for 100m and 75m levels were -4.00°F on October 25, (100m) and -3.44°F on October 18, (75m). Differential tempera tures are a measurement of atmospheric stability and used to calculate radioactive plume disper sions based on Gaussian Plume Models of continuous effluent releases.

Dew Point Temperatures and Relative Humidity Monthly average and extreme dew point and humidity temperatures for 2000 are provided in Table 29. These data are measured at the 10 meter level. The average dew point temperature was 32.34°F with a maximum dew point temperature of 71.43°F on May 12. Please note that dew point temperatures above 75°F are highly suspect and are possibly due to calm winds and high solar heating allowing the aspirated dew point processor to retain heat. The minimum dew point (dew point under 32°F is frost point) temperature was -4.16'F on December 20. Average relative humidity is 49.17 percent for the year. The maximum relative humidity was 100.00 per cent on December 30. The minimum relative humidity was not recorded due to the Dew Point instrument being out of service from June through September. It is possible to have relative hu midity above 100 percent, which is known as supersaturation. Conditions for super saturation have been met a few times at Davis-Besse due to its close proximity to Lake Erie and the evaporative pool of moisture available by such a large body of water.

Precipitation Monthly totals and extremes of precipitation at Davis-Besse for 2000 are given in Table 29. To tal precipitation for the year was 39.73 inches. The maximum daily precipitation total was 1.83 inches in October. The minimum was 0.40 inches recorded in March. It is likely that precipita tion totals recorded in colder months are somewhat less than actual due to snow/sleet blowing across the collection unit rather than accumulating in the gauge.

Lake Breeze and Lake Level Monitoring Lake Breeze is monitored at Davis-Besse because of its potential to cause major atmospheric/

dispersion problems during an unlikely radioactive release. A lake breeze event occurs during the daytime, usually during the summer, where the land surface heats up faster than the water, and therefore reaches higher temperatures than the water. The warmer air above the land rises faster because it is less dense than the cooler air over the lake. This leads to rising air currents 118

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report over the land with descending denser air over the lake. This starts a wind circulation, which draws air from the water to the land during the daytime, creating a "Lake Breeze" effect. This event could be problematic if a release were to occur because diffusion would be slow thus cre ating an adverse atmosphere to the surrounding site.

Lake and forebay levels are monitored at Davis-Besse to observe, evaluate, predict and dissemi nate high or low lake level information. This data is critical in the running of the plant due to the large amounts of water needed to cool plant components. If water levels get too low the plant operators can take measures for the safe shut down of the plant. Since Lake Erie is the shallow est lake in the Great Lakes, it is not uncommon for a plus or minus five feet lake level fluctuation to occur within an eight to ten hour period. High water levels also effect the plant due to emer gency transportation and evacuation pathways.

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report Land and Wetlands Management The Navarre Marsh, which is part of the Ottawa National Wildlife Refuge, makes up 733 acres of wetlands on the southwestern shore of Lake Erie and surrounds the Davis-Besse Nuclear Power Station. The marsh is owned by Toledo Edison and jointly managed by the U.S. Fish and Wild life Service and Toledo Edison. Navarre Marsh is divided into three pools. The pools are sepa rated from Lake Erie and each other by a series of dikes and revetments. Toledo Edison is re sponsible for the maintenance and repair of the dikes and controlling the water levels in each of the pools.

A revetment is a retaining structure designed to hold water back for the purpose of erosion con trol and to encourage beach formation. Revetments are built with a gradual slope, which causes waves to dissipate their energy when they strike the revetment. This encourages beach formation through passive deposition of sediment. A dike is a retaining structure designed to retain water for the purpose of flood control and to aid in managing wetland habitat. When used as a marsh management tool, dikes aid in controlling water levels in order to obtain desired vegetation and animal species. Manipulating water levels is one of the most important marsh management tools used in Navarre Marsh. Three major types of wetland communities exist in Navarre Marsh, the freshwater marsh, swamp forest, and wet meadow. Also, there exists a narrow dry beach ridge along the lakefront with a sandbar extending out into Lake Erie. All these areas provide essential food, shelter, and nesting habitat as well as a resting area for migratory birds.

Davis-Besse personnel combine their efforts with a number of conservation agencies and organi zations. The Ottawa National Wildlife Refuge, the Ohio Department of Natural Resources (ODNR), and the Black Swamp Bird Observatory work to preserve and enhance existing habitat.

Knowledge is gained through research and is used to help educate the public about the impor tance of preserving wetlands.

With its location along two major migratory flyways, the Navarre Marsh serves as a refuge for a variety of birds in the spring and the fall, where they rest and build up energy reserves before continuing their journey. The Black Swamp Bird Observatory captures, examines, bands, cata logues, and releases songbirds in the marsh during these periods.

Navarre Marsh is also home to wildlife that is typical of much of the marshland in this area, in cluding deer, fox, coyote, muskrats, mink, rabbits, groundhogs, eagles, hawks, owls, ducks, geese, herons, snakes and turtles. For the first time in recent history, a pair of mature American Bald Eagles chose the Navarre Marsh as their nesting site in late 1994, and fledged a healthy ea glet in July 1995. The young eagle was one of record 38 eaglets fledged in Ohio in 1995. A new nest was built in 1999-2000. It was one of over 60 Ohio nests, and fledged a pair of eaglets in the summer of 2000. Goose banding was conducted in June, in cooperation with the ODNR and the U.S. Fish and Wildlife Service. Over 100 Canada Geese were banded in about an hour.

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report Ohio's sixth Federal Junior Duck Stamp Art Contest was again held at Davis-Besse. Young Ohio artists in grades K-12 submitted nearly 800 entries in four age brackets. The Junior Duck Stamp Art Contest was designed to teach conservation through the arts and give students a chance to experience the beauty and diversity of wildlife. A total of 101 ribbons were awarded to young Ohio artists, with the state Best-of-Show entry submitted to Washington, D.C. to compete in the national contest with all other state Best-of-Show entries. The winner of this competition will be used to make this year's Junior Duck Stamp. The 1996 Ohio Junior Duck Stamp Art Contest winner of Best-of-Show, Adam Grimm, became the youngest artist ever to win the adult Federal Duck Stamp contest. His artwork was displayed on the federal duck stamp for the year 2000.

Davis-Besse also hosted a Volunteer Eagle Watchers Workshop. Training was given to over 80 volunteers who will be observing Ohio's expanding eagle population during the current breeding and nesting season.

Water Treatment Plant Operation Description The Davis-Besse Nuclear Power Station draws water from Lake Erie for its water treatment plant. The lake water is treated with chlorine, lime, and other chemicals to produce high purity water, which is used by many of the Station's cooling systems.

Treatment System Raw water from Lake Erie enters an intake structure, then passes through traveling screens which will remove debris greater than one-half inch in size. The water is then pumped to chlorine de tention tanks. Next, the water passes through one of two clarifiers. Davis-Besse uses upflow clarifiers, or precipitators, to remove sediment, organic debris, and dissolved agents from the raw water prior to filtration. Clarifiers combine the conventional treatment steps of coagulation, flocculation, and sedimentation into a single unit. Coagulation is the process by which a chemi cal, called a coagulant, is added, causing the small particles in the water to adhere to each other and form larger particles. During flocculation, the water is gently circulated, allowing these con glomerate particles to mass together further. Finally, during sedimentation, large conglomerate particles settle to the bottom of the clarifier. These processes normally require large separate tanks. However, the use of clarifiers saves both space and the manpower needed to operate the treatment plant.

AUTOMATIC SPUPUMPS WATWR TO DEMINERAWEL)

WATERW Figure 38: At Davis-Besse, raw water is drawn into the water treatment plant and processed to make water for plant systems.

After the clarifier, the water goes through a flow-splitting box, which equally divides the water flow to the Automatic Valveless Gravity Filters (AVGF). These AVGFs consist of a 50:50 ratio of anthracite to filter sand. During this filtration process, suspended matter is removed from the water by the anthracite and sand media. This filtering reduces the turbidity of the water.

After filtration, the water goes to a 32,000-gallon clearwell. The clearwell acts as a reservoir from which water can be drawn as needed for all systems, including firewater and demineralized water.

Domestic Water When Davis-Besse began operation over 20 years ago, all site domestic water was produced in the Water Treatment Facility. Operation of the Domestic Water Treatment and Distribution System, including the collection and analysis of daily samples, has been reportable to the Ohio Environmental Protection Agency.

Beginning in December 1998, domestic water needs at Davis-Besse have been met by the Carroll Township Water District. Since the Station no longer produces its own domestic water, these regulatory requirements have been discontinued.

Zebra Mussel Control Introduction The plant receives all of its water from an intake system from Lake Erie. Zebra mussels can se verely impact the availability of water for plant processes. Dreissena polymorpha, commonly known as the zebra mussel, is a native European bivalve that was accidentally introduced into 142

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report North American waters in 1986 and was discovered in Lake Erie in 1989. Zebra mussels are prolific breeders that rapidly colonize an area by secreting byssal threads that enable them to at tach to solid surfaces and to each other. Because of their ability to attach in this manner, they may form layers several inches deep. This poses a problem to facilities that rely on water intakes from Lake Erie because mussels may attach to the intake structures and restrict water flow.

Zebra mussels have not caused any significant problems at Davis-Besse, but mussels have been found attached to the intake crib (the structure that allows water to be pulled in from the lake) and the first section of the intake conduit (the pipe that connects the crib to the intake canal).

Mussels have also been found on the trash racks, and the intake bay #3 walls prior to the travel ing screens. These mussels are periodically cleaned using high-pressure water. Davis-Besse uses continuous low level chlorination of the intake bays to control the mussels.

The mussel population appears to be leveling off or declining. This is likely due to the increas ing clarity of Lake Erie. As the food source for the zebra mussel declines, mussel population de clines correspondingly.

Wastewater Treatment Plant Operation The WWTP operation is supervised by an Ohio licensed Wastewater Operator. Wastewater gen erated by site personnel is treated at an onsite extended aeration package treatment facility de signed to accommodate a flow of 38,000 gallons per day (gpd). In the treatment process, waste water from the various collection points around the site, called lift stations, enters the facility and is distributed to the surge tanks of the treatment plants.

The wastewater is then pumped into the aeration tanks. Here, sanitary waste is digested by mi croorganisms, which are provided with a source of oxygen. This is accomplished by the use of blowers. The mixture of organics, microorganisms, and decomposed wastes is called activated sludge. The treated wastewater settles in a clarifier, and the clear liquid passes over a weir, leaving the plant by an effluent trough. The activated sludge contains the organisms necessary for continued treatment, and is pumped back to the aeration tank to digest more incoming waste water. The effluent leaving the plant is pumped to the wastewater basin (NPDES Outfall 601) where further treatment takes place.

Summary of 2000 Wastewater Treatment Plant Operations All wastewater parameters were within specifications during the year 2000.

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report National Pollutant Discharge Elimination System (NPDES) Reporting The OEPA has established limits on the amount of pollutants that Davis-Besse may discharge to the environment. These limits are regulated through the Station's National Pollutant Discharge Elimination System (NPDES) permit, number 2IB0001 1

FD. Parameters such as chlorine, suspended solids and pH are monitored under the NPDES permit. Toledo Edison personnel pre pare the NPDES Reports and submit them to the OEPA of each month.

Davis-Besse has six sampling points described in the NPDES permit. Five of these locations are discharge points, or outfalls, and one is a temperature monitoring location. Descriptions of these sampling points follow:

Outfall 001 Collection Box: At a point representative of discharge to Lake Erie.

Source of Wastes: Low volume wastes (Outfalls 601 and 602), Circulating Water system blowdown and service water.

Outfall 002 Area Runoff: Discharge to Toussaint River Source of Wastes: Storm water runoff, Circulating Water pump house sumps.

Outfall 003 Screenwash Catch Basin: Outfall to Navarre Marsh.

Source of Wastes: Backwash water and debris from water intake screens.

Outfall 601 Wastewater Plant Tertiary Treatment Basin: Discharge from Wastewater Treatment Plant.

Sources of Wastes: Wastewater Treatment Plant.

Outfall 602 Low volume wastes: Discharge from settling basins.

Sources of wastes: Water treatment residues, Condensate Polishing Holdup Tank decant, and Condensate Pit sumps.

Sampling Point 801 Intake Temperature: Intake water prior to cooling operation.

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report 2000 NPDES Summary During 1996, the NPDES permit was renewed by the Ohio EPA. This permit expired on October 31, 2000, and a renewal application was submitted in May, 2000. The previous permit will be in effect until the new permit is issued by the Ohio EPA. A new sampling requirement with outfall designation 004 was added to the permit renewal application. This will be used to monitor the water drained from the Circulating Water System into the two ponds adjacent to the Cooling Tower during outages. There was one violation of the NPDES permit during 2000 due to a discharge of hydrazine through internal Outfall 602. There was no detectable discharge of hydrazine through external Outfall 001.

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report Chemical Waste Management The Chemical Waste Management Program for hazardous and nonhazardous chemical wastes generated at the Davis-Besse Nuclear Power Station was developed to ensure wastes are man aged and disposed of in accordance with all applicable state and federal regulations.

Waste Management Resource Conservation and Recovery Act The Resource Conservation and Recovery Act (RCRA) is the statute which regulates solid haz ardous waste. Solid waste is defined as a solid, liquid, semisolid, or contained gaseous material.

The major goals of RCRA are to establish a hazardous waste regulatory program to protect hu man health and the environment and to encourage the establishment of solid waste management, resource recovery, and resource conservation systems. The intent of the hazardous waste man agement program is to control hazardous wastes from the time they are generated until they are properly disposed of, commonly referred to as "cradle to grave" management. Anyone who gen erates, transports, stores, treats, or disposes of hazardous waste are subject to regulation under RCRA.

Under RCRA, there are essentially three categories of waste generators:

"* Large quantity Generators - A facility which generates 1000 kilograms/month (2200 lbs./month) or more.

"* Small quantity Generators - A facility which generates less than 1000 kilograms/

month (2200 lbs./month).

"* Conditionally Exempt Small Quantity Generators - A facility which generates 100 kilo grams/month (220 lbs./month).

In 2000, the Davis-Besse Nuclear Power Station qualified as a large quantity generator due to a one-time waste generated in September from an on-site sodium hypochlorite tank leak that re sulted in the generation of 50,166 pounds of hazardous waste. The quantity of all routine waste streams generated remained within small quantity generator status. Other hazardous wastes gen erated include 2,348 pounds of paints and solvents, 1,118 pounds of silver plating waste and 250 pounds of expired laboratory chemicals. Davis-Besse personnel also continuously strive in identifying alternate ways to reduce hazardous waste generation.

Non-hazardous waste disposed of in 2000 included 4,600 gallons of used oil, 1,210 gallons of oil filters and solid oily debris and 30 tons of a sand and anthracite water filter media. Other non hazardous regulated waste generated included 800 gallons of other chemicals such as microfilm process chemicals and polystyrene resins.

RCRA also mandates other requirements such as the use of proper storage and shipping contain ers, labels, manifests, reports, personnel training, spill control plan and an accident contingency plan, all of which are part of the Chemical Management Program at Davis-Besse. The following are completed as part of the hazardous waste management program to ensure compliance with the RCRA regulations.

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report Inspections

" Chemical Waste Accumulation Areas are designated throughout the site to ensure proper handling and disposal of chemical waste. These, along with the Chemical Waste Storage Area, are routinely patrolled by security personnel and inspected weekly by FirstEnergy Nuclear Operating Company personnel. All areas used for storage or accumulation of hazardous waste are posted as such with warning signs, and drums are color-coded for easy identification of waste categories by Davis-Besse employees.

" Waste Inventory Forms Inventory forms are placed on waste accumulation drums or provided in the accumu lation area to allow employees to record the waste type and amount as it is added to the drum. This ensures that incompatible wastes are not mixed and also identifies the drum contents for proper disposal.

Emergency Response Planning Comprehensive Environmental Response, Compensation, and Liability Act The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA, sometimes referred to as Superfund) established a federal authority and source of funding for re sponding to spills and other releases of hazardous materials, pollutants, and contaminants into the environment. Superfund establishes "reportable quantities" for several hundred hazardous mate rials and regulates the cleanup of abandoned hazardous waste disposal sites.

Superfund Amendment and Reauthorization Act (SARA)

Superfund was amended in October 1986 to establish new reporting programs dealing with emergency preparedness and community right-to-know laws. As part of this program, CERCLA is enhanced by ensuring that the potential for release of hazardous substances is minimized, and that adequate and timely responses are made to protect surrounding populations.

Davis-Besse conducts site-wide inspections to identify and record all hazardous products and chemicals onsite as required by SARA. Determinations were made as to which products and chemicals were present in sufficient quantities to report.

Annual SARA reports are submitted to local fire departments, and local and state planning com missions by March 1 for the preceding calendar year. No additional chemical products were identified for calendar year 2000.

Spill Kits Spill control equipment is maintained throughout the Station at chemical storage areas and at ap propriate hazardous chemical and oil use points. Equipment in the kits may include such items as chemical resistant coveralls, gloves, boots, decontamination agents, absorbent cloth, goggles, and warning signs.

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report Other Regulating Acts Toxic Substances Control Act (TSCA)

The Toxic Substance Control Act (TSCA) was enacted to provide the USEPA with the authority to require testing of new chemical substances for potential health effects before they are intro duced into the environment, and to regulate them where necessary. This law would have little impact on utilities except for the fact that one family of chemicals, polychlorinated biphenyls (PCBs), has been singled out by TSCA. This has resulted in an extensive PCB management system, very similar to the hazardous waste management system established under RCRA.

In 1992, Davis-Besse completed an aggressive program that eliminated PCB transformers onsite.

PCB transformers were either changed out with non-PCB fluid transformers or retrofilled with non-PCB liquid.

Retro-filling PCB transformers involves flushing the PCB fluid out of a transformer, refilling it with PCB-leaching solvents and allowing the solvent to circulate in the transformer during op eration. The entire retro-fill process takes several years and will extract almost all of the PCB.

In all, Davis-Besse performed retro-fill activities on eleven PCB transformers between 1987 and 1992. The only remaining PCB containing equipment onsite are a limited number of capacitors.

These capacitors are being replaced and disposed of during scheduled maintenance activities.

Clean Air Act The Clean Air Act identifies substances that are considered air pollutants. Davis-Besse holds an OEPA permit to operate an Air Contaminant Source for the station Auxiliary Boiler. This boiler is used to heat the station and provide steam to plant systems when the reactor is not operating.

A report detailing the Auxiliary Boiler operation is submitted annually.

The Ohio EPA has granted an exemption from permitting our six emergency diesel engines, in cluding the Station Blackout Diesel Generator, the 2 Emergency Diesel Generators, the Emer gency Response Facility Diesel Generator, the Miscellaneous Diesel, and the Fire Pump Diesel.

These sources are operated infrequently to verify their reliability, and would only be used in the event of an emergency.

In response to recent "Clean Air Act Title V' legislation, an independent study identifying and quantifying all of the air pollution sources onsite was performed. Of particular significance is asbestos removal from renovation and demolition projects for which USEPA has outlined spe cific regulations concerning handling, removal, environmental protection, and disposal. Also the Occupational Safety and Health Protection Administration (OSHA) strictly regulates asbestos with a concern for worker protection. Removal teams must meet medical surveillance, respirator fit tests, and training requirements prior to removing asbestos-containing material. Asbestos is not considered a hazardous waste by RCRA, but the EPA does require special handling and dis posal of this waste under the Clean Air Act.

148

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report Transportation Safety Act The transportation of hazardous chemicals, including chemical waste, is regulated by the Trans portation Safety Act of 1976. These regulations are enforced by the United States Department of Transportation (DOT) and cover all aspects of transporting hazardous materials, including pack ing, handling, labeling, marking, and placarding. Before any wastes are transported off site, Davis-Besse must ensure that the wastes are identified, labeled and marked according to DOT regulations, including verification that the vehicle has appropriate placards and it is in good oper ating condition.

Other Programs Underground Storage Tanks According to RCRA, facilities with Underground Storage Tanks (USTs) are required to notify the State. This regulation was implemented in order to provided protection from tank contents leaking and causing damage to the environment. Additional standards require leak detection systems and performance standards for new tanks. At Davis-Besse two 40,000 gallon and one 8,000 gallon diesel fuel storage tanks are registered USTs.

Waste Minimization and Recycling Municipal Solid Waste (MSW) is normal trash produced by individuals at home and by indus tries. In some communities, MSW is burned in specially designed incinerators to produce power or is separated into waste types (such as aluminum, glass, and paper) and recycled. The vast majority of MSW is sent to landfills for disposal. As the population increases and older landfills reach their capacity, MSW disposal becomes an important economic, health, and resource issue.

The State of Ohio has addressed the issue with the State Solid Waste Management Plan, other wise known as Ohio House Bill 592. The intent of the bill is to extend the life of existing land fills by reducing the amount of MSW produced, by reusing certain waste material, and by recy cling other wastes. This is frequently referred to as "Reduce, Reuse, and Recycle."

Davis-Besse has implemented and participated in company wide programs that emphasize the reduction, reuse, recycle approach to MSW management. Improved efficiency in collection and transportation resulted in a two-year reduction of approximately 71 percent for disposal cost.

An active Investment Recovery Program has greatly contributed to the reduction of both hazard ous and municipal waste generated by evaluating options for uses of surplus materials prior to the materials entering Davis-Besse's waste streams. Such programs include paper, cardboard, alumi num cans, used tires, and metals recycling or recovery. Paper and cardboard recycling is typi cally in excess of 50 tons annually. This represents a large volume of recyclable resources, which would have otherwise been placed in a landfill. Aluminum soft drink cans are collected on site for the Boy Scouts to recycle. Additionally, lead-acid batteries are recycled and tires are returned to the seller for proper disposal.

149

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report Although scrap metal is not usually considered part of the MSW stream, Davis-Besse does col lect and recycle scrap metals. The metals are sold at current market price to a scrap dealer for re source recovery. These programs are continuously being expanded and reinforced as other com ponents of MSW stream are targeted for reduction.

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report Appendix A Interlaboratory Comparison Program Results Environmental, Inc., Midwest Laboratory, formerly Teledyne Brown Engineering Environmental Services Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples (e.g., milk or water) containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.

Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used.

The results in Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water and air filters during the past twelve months. Data for previous years is available upon request.

This program was conducted by the U.S. Environmental Protection Agency Office of Research and Development National Exposure Research Laboratory Characterization Research Division-Las Vegas, Nevada.

The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various International Intercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2.

Results of crosscheck testing with Teledyne Brown Engineering are also listed.

Table A-3 lists results of the analyses on in-house "spiked" samples for the past twelve months. All samples are prepared using NIST traceable sources. Data for previous years available upon request.

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report APPENDIX B DATA REPORTING CONVENTIONS 175

Davis-Besse Nuclear Power Station 2000 Annual Radiological Environmental Operating Report Data Reporting Conventions 1.0. All activities, except gross alpha and gross beta, are decay corrected to collection time or the end of the collection period.

2.0. Single Measurements Each single measurement is reported as follows: x 4s where: x = value of the measurement; s = 2s counting uncertainty (corresponding to the 95% confidence level).

In cases where the activity is less than the lower limit of detection L, it is reported as: <L, where L = the lower limit of detection based on 4.66s uncertainty for a background sample.

3.0. Dup~licate an&=se 3.1 Individual results: For two analysis results; x, +/- s, and X2 S2

]poedresult x +/- s; where x = (1/2) (xj + x 2) and s (1/2) L+ S2 3.2. Individual results: <L 1 , <L 2 Re.ortd result <L, where L = lower of L, and L 2 3.3. Individual results: x+/- s, <L Reported result: x +/- s if x > L; <L otherwise.

4.0. Computation of Averages and Standard Deviations 4.1 Averages and standard deviations listed in the tables are computed from all of the individual not be measurements over the period averaged; for example, an annual standard deviation would the average of quarterly standard deviations. The average x and standard deviation s of a set of n numbers x,, x2... x, are defined as follows:

n s n-i 4.2 Values below the highest lower limit of detection are not included in the average.

is reported.

4.3 If all values in the averaging group are less than the highest LLD, the highest LLD two 4.4 If all but one of the values are less than the highest LLD, the single value x and associated sigma error is reported.

4.5 In rounding off, the following rules are followed:

is dropped, and the 4.5.1. If the figure following those to be retained is less than 5, the figure retained figures are kept unchanged. As an example, 11.443 is rounded off to 11.44.

is dropped 4.5.2. If the figure following those to be retained is equal to or greater than 5, the figure and the last retained figure is raised by 1. As an example, 11.445 is rounded off to 11.45.

Appendix A Interlaboratory Comparison Program Results Environmental, Inc., Midwest Laboratory, formerly Teledyne Brown Engineering Environmental Services Midwest Laboratory has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples (e.g., milk or water) containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on a laboratory's analytical procedures and to alert it of any possible problems.
