Box 128 Jacksonville, NC 28541 Dear Mr. Hargett: I This is in response to your letter of December 11, 2000, in which you have requested an extension of CAMA General Permit No. 26691-C. This permit was been issued to the City of Jacksonville and authorizes the temporary placement of aerators in Wilson Bay in order to evaluate their effectiveness in improving water quality. This permit was issued on September 6, 2000 and is due to expire on December 31, 2000. According to your letter, the City would like an additional 3 -month extension in order to continue the evaluation of this innovative technology. Please be advised that CAMA General Permit No. 26691-C has been extended until March 6, 2001 so that continued monitoring and evaluation of these devises may continue. If the City believes there is a likelihood for the aerators to become a permanent feature in Wilson Bay, a CAMA major permit will be needed. Since it t takes approximately 75 days to process an application, the City should submit their application request to the Morehead City District Office as soon as possible. Thank you for your interest in this matter. If you have any questions, please contact Ms. Tere Barrett or myself at our Morehead City office Sincerely, C"s Charles S.

Instream management uses devices and techniques applied directly to our waters, public and private, to provide flood control and treat water problems in situ. The InStreem"Water Units being developed by Battelle are thought to be the key to making instream management a reality. Despite unprecedented spending on water management by the U.S., some 40% of our waters are unfit for human or ecosystem use. Regional failures in water quality have occurred in the areas like the Chesapeake Bay, the Neuse Valley, the Imperial Valley, the Everglades, and the Mississippi Delta. These examples highlight the shortcomings of conventional offline approaches to water management. Vast reservoirs of nutrients and other pollutants are stored in water body sediments, of which Wilson Bay is an example. In many areas, even if all pollutant inputs stop today, water bodies would require many decades to return a viable ecosystem. The aim of instream management is to solve water problems now by providing nature with the additional tools to cope with 21st Century pollutants. The tools of instream management include the shellfish plantings begun by the City of Jacksonville and North Carolina State University in Wilson Bay. This project will determine if the addition of InStreem Water Units will provide a more complete system that treats both sediments and the water column. Unlike conventional methods, the InStreem'system is designed to convert existing water bodies into extended aeration systems based on proven oxidation ditch designs. Furthermore, unlike conventional methods, the capacity or placement of in situ systems can be easily altered to accommodate changing needs and conditions. -The system can be installed in one day. -Low maintenance •Current flow patterns are not changed, simplifying permitting and operation. The InStreem°' Water Unit is the flow component for the system. The flow rate of a 5 horsepower unit is 17-50 NIGD (million gallons per day), with circulation effects exceeding 200 MGD. The following add-on products or options may be available for the InStreem"system: *Pontoon or Fixed Installations -Aeration Enhancement Equipment -Ozone Generation and Injection -Filter and Adsorption Media -Fuel, Electric, or Solar Powered Motors -Auxiliary Pumping for feeding wetlands or irrigation •VOC and Odor Removal Equipment The portable InStreem Water Units were manufactured by Choctaw Manufacturing & Development Corporation and were transported to location via trailer trucks. Aeration of water by InStreem"discs. Y Another InStreem"Application A new approach for lagoon treatment As the 21st Century approaches, the quality of world water resources is becoming a major public concern. One challenge for water managers is the cost-effective treatment agricultural wastes. Especially in the U.S. and Europe, changes in the agricultural sector have led to consolidated production of many farmed commodities in relatively small factory facilities. Waste products that were once spread over entire regions and hundreds of farms are now consolidated in a few farms. These changes have been blamed for severe environmental impacts in many areas of the U.S. An example of instream water management is the use of portable devices and techniques applied directly to existing or new farm lagoons. This offers a rapid, flexible, and cost-effective method for solving some agricultural waste problems.

PROJECT DESCRIPTION AND TECHNICAL APPROACH The City of Jacksonville, NC, has enlisted the support of the U.S. Army Corps of Engineers and North Carolina State University to support the evaluation and restoration of Wilson Bay. Several options have been presented by various organizations with the intent of restoring the Bay to a healthy ecosystem. One such option includes the installation of in -water flow enhancement and aeration systems that will de -stratify the DO levels; induce flow into the bay, and establish an aerobic cap on the sediments. This last goal is thought to be very important for the re- introduction of benthos and the minimization of undesirable constituents leaching from the anaerobic sediments. This Project Plan is focused on demonstrating that Battelle's InStreemTM technology is capable of facilitating the desired objectives. 1.1 Background "Wilson Bay is an estuarine cove in the New River, in Onslow County North Carolina. Fresh water enters the Bay from the New River, four urban streams and several streams located within Marine Corps Base Camp Lejeune. Tidal input into the bay is minimal (< 1 ft.). Until recently two sewage treatment plant outfalls, one from the City of Jacksonville, Waste Water Treatment Plant, and the second from the Camp Geiger Waste Water treatment plant, contributed to the contaminant load in the Bay. Although the Bay was once used for recreational activity, elevated fecal coliform pollution has prevented recreational use of the bay for decades. Both waste treatment facilities have been decommissioned and fecal coliform loads in the Bay have been markedly reduced. Bottom chemical characterization studies within the Bay have determined that organic and inorganic chemical loads are minimal. Chromium, copper, lead, nickel, silver, and zinc were detected at low levels, and these contaminants were primarily identified at the location of the wastewater treatment plant outfall. Some polyaromatic hydrocarbons and DDT derivatives were also detected. Remediation activities including the decommissioning of the sewage treatment plants and removal of an old dock with creosote treated posts have already been implemented to reduce the total PAH load. However, a thick blanket of organic sediment covers the bottom of the Bay. Biologic oxygen demand from these organic sediments is substantial and the bottom of the Bay experiences sustained periods of hypoxia and anoxia between June and September of each year. During periods of bottom anoxia in eutrophied systems like Wilson Bay, a flux of phosphorus, hydrogen sulfide, and ammonia move from the sediment into the water column. Although complete removal of the organic sediments would substantially reduce bottom oxygen demand, the volume of sediments that would have to be removed and held in upland disposal sites precludes dredging. Partial dredging would reduce the size of the disposal area required, but would possibly expose strata with even higher oxygen demand than the surficial sediments. Capping sediments with a non-organic layer of material has been proposed but rejected due to the depth and softness of Bay sediments, uncertainty as to its ability to alter bottom anoxia, and possible ecosystem impacts. As an alternative, time-limited placement of aeration equipment has been proposed to de -stratify the water column during summer months, increase bottom oxygen saturation, and increase flow. However, the feasibility of using aeration equipment in the Bay in this manner has not been evaluated. Accordingly, the following feasibility assessment is proposed to evaluate the ability of aeration equipment to: 1) de -stratify the water column; 2) enhance bottom oxygen saturation; and 3) increase flow within the Bay. Expected Results: We anticipate that de -stratification of the water column will be rapid. A steady state of DO in the 1.5 - 2 PPM range is expected. Measurable changes in sediments will take longer, taking weeks to months. Increasing bottom dissolved oxygen levels should help increase the likelihood that benthic organisms will return to the bottom of the Bay. In addition, we anticipate reductions in the flux of nutrients."' The instream approach for water management has been under sustained development at Battelle for 4 years, and is the result of over 15 years of research and invention by Battelle's Henry Pate. The current concept includes multiple technologies with the InStreemTM water unit (IWU) being the central technology platform. Mr. Pate's concept • revolves around the process of managing the water column in situ — rather than removing the water or sediments I Dr. Jay Levine, Wilson Bay Water Quality Initiative, Aeration Feasibility Study Draft, June 23, 2000 BATTELLE Use or disclosure of data appearing on this sheet is subject to the approval of the Battelle Project Manager. Project Plan August 27, 2000 Wilson Bay, NC Page: 2 • from the natural or man made systems and makes use of the IWU's unique ability to influence the movement of the water. The extremely efficient water movement makes this technology capable of influencing movement of significant amounts of water (creating an apparent in situ pipeline) that has been observed to facilitate flood control and replicate natural waterway circulation. Supplemental to this water movement or entrained (dragged) flow is the observed ability of the IWU to provide aeration and the establishment of a contact chamber that facilitates the addition of treatment enhancing chemistry to remove recalcitrant constituents of concern. The basic InStreemTM unit consists of 10 to 20 shaft -mounted discs (diameter 4.5') to move water, speed reducer, disc chamber, baffles, and flotation gear. Discs are vertical in the water column, spaced from 5 inches apart and immersed from 7 to 21 inches. The current unit dimensions of the basic InStreemTM unit are 132 inches long, 80 inches wide, and 101 inches high. With the addition of the floats and directional baffles, the length and width dimensions increase to 276 inches and 152 inches respectively. The system is powered by 5-10 hp natural gas, diesel or electric motors. For the purpose of the Wilson Bay demonstration, Battelle is supplying three 10 -disk units powered by 5 hp, 220 volt, single-phase electric motors. Energy is applied efficiently to the discs to move the most water in a horizontal plane. The discs work by dragging water, not by pushing or lifting. Since rotational speed is low, without sharp impeller surfaces, impact on biota, including resident and migrating fish populations is minimized or non-existent. Based on field tests and data from the disc manufacturer (U.S. Filter, Inc.), the pumping rate of this unit has been in the range of 2 to 6 million gallons per day (MGD) per unit of horsepower (MGD/hp) with induced circulation greater than 57 MGD/hp. Such movement of water is made possible by the drive unit's unique configuration and its employment in open channels with some hydraulic head. As water is moved toward the unit's outlet, water adjacent to the unit's inlet must move to replace that water, lessening the energy required to overcome the water's inertia as it contacts the disc -drive. Based on that process, but on a larger scale, there is a flow re -enforcement, imparting additional energy to the water column, caused by the unit's deployment in an open channel. By using the unit to move water past one point, additional water upstream must move to replace it, increasing the circulation effects. • 1.2 Objectives of the Study 1.2.1 Provide for the transportation, installation, and operation of three InStreemTM systems. The InStreemTM system satisfies the specification defined in the Request For Proposal. The Choctaw Manufacturing & Development Corporation (CMDC) in Hugo, Oklahoma manufactured the three InStreem"m Water Units. The IWUs will arrive in Jacksonville, NC via a trailer truck. They will then be unloaded from the truck. A field team of Battelle and CMDC representative will attach the floatation tanks and baffles to the InStreemTm platforms. When assembled, a local crane company under contract by Battelle will move the IWUs to the New River. Once in water, the field team will tow the IWUs to locations in Wilson Bay. Two units will be installed on the north side of the Bay and separated by — 200M . The third unit will be installed on the East Side of the Bay — adjacent to Camp Lejeune. Roughly 600 feet of #6 AWG, 3 strand, SEOW quality power cable will be supplied with the IWUs. The City will supply electric power from shore points to run the units. Ground Fault Interruption will be coordinated at the time of installation. Installation of signage identifying electrical hazard, underwater electrical line, and language describing the test and IWU will also occur. Battelle has contracted one working boat for the first week of the study and anticipates that the NCSU research vessel will be available for use throughout the study. Further, and as needed, we anticipate that NCSU field personnel will be made available to operate the vessel and support this effort. 1.2.2 Demonstrate the efficacy of the IWUs. Fieldwork will commence with the baseline sampling of the bay across four transects that traverse the bay (see map on following page). When baseline work is completed, the IWUs will be started and allowed to rum overnight. During the remainder of the week, the parameters will be measured again at the same sampling points (using a GPS). The field team will further examine the same sampling points throughout the 12 -week study. The following parameters will be studied before and during InStreemT"" operation. • BATTELLE Use or disclosure of data appearing on this sheet is subject to the approval of the Battelle Project Manager.

Water column DO readings at 1' intervals to within 1" of the bottom will be taken along the four transects. DO readings will be monitored during each of the sampling times: pre- InStreern ", weeks #1, #3, #6, #8 (optional), and #12 of InStreerrJm operation. We anticipate seeing de -stratification and the development of an aerobic cap at the sediments. • Benthos Enumeration. A benthos enumeration that was conducted during the past month will serve as baseline data. Another enumeration study will occur at least one time during the course of the evaluation. Two additional benthos enumeration studies will be conducted with the support of NCSU researchers. The post-InStreemTm data will be compared to the baseline data. We anticipate that the post-InStreemT"" study for this protocol will be executed at week #12. • Flow measurements. Surface velocities and velocities within the water column will at 1' intervals at the sampling stations. Floating objects will be tracked for velocity and vector from the point of release. Flow measurements will also be taken at the inlet to Wilson Bay to compare with baseline observations. • Sediment Profile Imagery. Battelle will establish fixed sampling stations. At least two photos will be taken at each station. We will collect a set of data from throughout the expected area of improvement plus some that are outside of this area to act as controls. These parameters will be monitored before and during InStreemTM' (pre-InStreemTm, week#1, week #3, week #6, week #8 (optional), and week #12). We anticipate a change in sediment color as an aerobic cap is achieved. Battelle will also measure and analyze clarity, pH, conductivity, turbidity, temperature, salinity, total dissolved solids, specific gravity, and oxidation-reduction potential during the study to determine the effects of InStreem"m on water quality in Wilson Bay. 1.2.3 Demobilize the InStreemT"" Units from Wilson Bay at the completion of the study. This phase may be delayed if further operational testing is warranted. 1.2.4 Compile and analyze the data, and generate a report of findings. The final draft report will be submitted to the City of Jacksonville for dissemination and technical review. Comments received will be incorporated and a final report published. We expect the final report to be published NLT 2 January 2001 (or before if comments are minimal). 1.3 Mobilization and Sampling The field survey will begin within 10 days of notice to proceed. All sampling is scheduled for completion no later than November 20, 2000. The field team will include representatives from Battelle. Roles and responsibilities of the field team are discussed in Section 2 of this Project Plan. A detailed schedule of field activities and deliverables is provided in Section 3. 1.3.1 Sampling Locations We will collect samples in Wilson Bay as described below. Table 1-1 indicates the sampling locations and sampling station identification (see map). A sampling plan with field sampling protocol may be found in Attachment B or this plan.

Equipment includes a Petite PONAR, SPI, depth gage, sorting trays, buckets, Horiba U-22 multi -parameter instrument and probe. (See Attachment B for the project -specific checklist). • Assemble decontamination equipment and supplies. These include de -ionized water, solvents, non - phosphate detergent, scrub brushes, and waste containers. • Review Equipment List for Field Collections. Battelle will be performing actual collection of field samples and providing all equipment necessary to collect grab samples and water parameter probe analyses. Field documentation forms will include: • Accident Prevention Plan (Attachment A, see Section 1.4) • Field log book • Field log forms (Attachment B) • Chain of custody forms (as necessary) 1.3.3 Workboat and Navigation Battelle will be responsible for providing the primary workboat. The use of the NCSU project boat may be coordinated on site. Battelle will adhere to the applicable health and safety measures found in the Corps of Engineers EM 385-1-1, Safety and Health Requirements Manual. The workboat engines will be shut off during sample collection activities. However, if conditions require leaving the engines engaged, the workboat will be situated such that exhaust is downwind from sampling operations. Battelle will provide a qualified Global Positioning System (GPS) operator to position the workboat. Sampling stations will be determined by differential GPS with accuracy of ±10 feet or better. The depth of water, as indicated by Mean Low Water (MLW) elevation shown on the chart near each sampling location, will be maintained as closely as possible. Water depths will be determined with an accuracy of ±0.1 feet. The actual sampling location . coordinates (from GPS) will be recorded. BATTELLE Use or disclosure of data appearing on this sheet is subject to the approval of the Battelle Project Manager. Project Plan August 27, 2000 Wilson Bay, NC Page: 6 • 1.3.4 Sampling Measurements • Flow. Battelle will conduct surface and water column flow measurements. The surface flow will be measured using floating objects and/or tracing dye. A profile of flow velocities will be taken at each of the sampling stations at 1' increments to the bottom using a propeller -type velocity meter. • Sediment Grab Sample Collection. Battelle will be responsible for collecting grab samples at the locations listed in Table 1-3. Sufficient material will be collected for qualitative benthic enumeration. A Petite Punar grab sampler will be used for collection of all samples for this analysis. Each grab will be inspected for acceptability. An acceptable grab is at least 1/2 full and level on at least one side. In addition, the grab should not be overfull; sediment should be below the level of the open doors. If the grab is rejected, the reasons for rejections will be recorded in the survey logbook. • Sediment Profile -Imaging. The field team will take photographs of the first 8" of bottom sediment with the use of a sediment profile imager (SPI). The SPI is an upside down periscope that uses a mirror placed at 45° at the bottom of the unit to reflect the vertical image to the surface. There a camera will be used to generate images of the sediments. • Multi -Parameter Probe (pH, Conductivity, Turbidity, DO, Temperature, Depth, Salinity, TDS, Specific Gravity, and ORP). A Horiba U22 instrument and probe will be used to collect DO measurements at 1' increments down to the bottom of the water column (within 1 ") at each of the sampling stations. Battelle will also collect data for pH, conductivity, turbidity, temperature, depth, salinity, total dissolved solids, specific gravity, and oxidation-reduction potential at the same increments. • 1.3.5 Decontamination Decontamination is the process of neutralization, washing, and rinsing exposed outer surfaces of equipment/probes to minimize the potential for contaminant migration and/or cross -contamination. This requirement differs from the personnel decontamination that is described in the Accident Prevention Plan. See Attachment B. 2.

SCHEDULE OF MILESTONES AND DELIVERABLES A Gantt Chart shown in Figure 3-1 on the following five pages summarize the schedule of field activities as well as deliverable due dates. The actual dates may vary from those listed below depending on actual schedule of events. However, the following items are critical to be aware of during this project: The number of days actually proposed for field activities is 16, excluding weather days (two days are for mob/demob). If work must proceed beyond the 16 days, the project manager, field chief scientist or program manager must be advised as soon as this becomes a possibility; Weather Days – If a weather day occurs, the project manager, field chief scientist or program manager must be notified immediately so the client can be made aware that field days may exceed the proposed six days. 4. QUALITY ASSURANCE and QUALITY CONTROL All equipment will be calibrated according to manufacturer's instructions. Detailed field notes will be kept in a field logbook and on datasheets (see Attachment B). The documentation will include any deviations to the protocol, • observations of activity, water characteristics, and time taken. After each day's data collection, the field notes will be reentered into electronic form The field notes are important for this study and future use to establish trends and or correlations. Sample integrity will be maintained through careful labeling, following established sampling protocols. 5. HEALTH AND SAFETY The Accident Prevention Plan (see Attachment A) addresses health and safety issues identified specific to this project and provides additional information for the field team. All field personnel involved with sampling for the purpose of physical or chemical analysis are required to be familiar with and comply with this Accident Prevention Plan. The contents of this plan reflect anticipation of the types of activities to be preformed, knowledge of the physical characteristics of the site, and consideration of the preliminary chemical data from previous investigations at the site. The plan may be revised based on new information and/or changed conditions during site activities. Revisions will be documented in the project records.

Slips can be minimized by wearing boots with good tread, made of an appropriate material for the weather conditions. (k) Sampling from a boat or other floating platform requires careful attention to minimize the risk of falling down or of falling overboard. (1) Keep work areas as free as possible from items that could cause one to trip. (m) All personnel using field equipment will be trained in the safe use of the equipment prior to initiation of field activities. Only trained, experienced personnel will operate the heavy equipment. All personnel on deck at the time of equipment deployment will wear hard hats and safety vests. Personnel will stand clear of and will wear steel -toed boots at all times when on the vessel. (n) Personal flotation devices (PFDs) will be wom while working from the boat (for offshore sampling), unless wearing the PFD poses more of a safety risk because of increased bulk or awkwardness. The Site Safety Officer will make the decision regarding the use of PFDs. (o) Personnel suspected of suffering from hypothermia require immediate treatment to restore the body temperature to normal. Current medical practice recommends slow warming by professional medical care. This can be accomplished by moving the person to a sheltered area (warm room preferable) and wrapping them in a blanket. (p) In general, field team members will be equipped for the normal range of weather conditions. The SHSO will be aware of current weather conditions, and of the potential for those conditions to pose a hazard to the field crew. Some conditions that might force work stoppage are • electrical storms, high winds or waves and freezing temperatures.

Project Plan August 27, 2000 Wilson Bay, NC Attachment A Page: A-6 • SECTION 11: DECONTAMINATION PROCEDURES Decontamination of disposable PPE will consist of proper removal and disposal of gloves. All field personnel should wash exposed skin of the hands and face thoroughly with soap and water at the end of the day and before eating. The following decontamination of equipment is required: ❑ Decon Pad (Plastic Sheet) 0 Dry Brushes X Detergent Soap X Trash Cans/Bags X Wet Brushes ❑ Other Decontamination Solution: X Buckets X Water SECTION 12: EMERGENCY PROCEDURES On-site personnel will use the following standard emergency procedures. The Site Safety Officer shall be notified of any on-site emergencies and be responsible for ensuring that the procedures are followed. A portable first aid kit shall be accessible on site, along with a cellular telephone. Routes to the nearest hospital should be in the staging area and in the site vehicles and on the research vessel. Personal Iniury in the Work Zone DESIGNATED EMERGENCY SIGNAL: 3 long air homs Upon notification of an injury in the Work Zone, the designated emergency signal shall be sounded. In any life-threatening situation, the heath and safety of the individual will take precedence over all procedures designed for protection against environmental contamination at the site. The nearest workers should immediately assist any person who shows signs of medical distress or who has suffered an accident. The Site Manager or SHSO should be summoned as soon as possible. If a breathing or hear problem is apparent, loosen the clothing around the victim's neck and chest and call for emergency medical services immediately. Should it be determined that no threat to life is present, the Site Manager shall direct the injured person through such decontamination procedures as are consistent with the nature of the illness or accident. The area surrounding any accident site is not to be disturbed until the Site Manger has cleared any changes to the site. • Fire/Explosion DESIGNATED EMERGENCY SIGNAL: 3 lone air horns The first step in fighting a fire onboard a boat is to sound the alarm and alert the captain and crew so the fire can be fought as a team. The following steps should be taken when fighting fire: apply an extinguishing agent either by using a fire extinguisher (or water to wood or other materials of this type); if practical, jettison the burning material reduce the air supply by closing hatches, doors, vents and ports if effective; make preparations to abandon ship by donning life vests, deploying a life raft, and signaling for assistance by radio or any other means available. Other Equipment Failure If any other equipment (i.e., air monitoring) on site fails to operate properly, the Field Team Leader and Site Safety Officer shall be notified and then determine the effect of this failure on continuing operations on site. If the failure affects the safety of personnel or prevents completion of the Work Plan tasks, all personnel shall leave the Work Zone until the situation is evaluated and appropriate actions taken. is Evacuation and Decontamination Emergency evacuations from the vessel will be conducted in the event of an uncontrolled fire, explosion, or other catastrophe, which places site personnel in a life-threatening situation or risk of personal injury. In the event of these incidents, the main objective is to remove personnel from the vessel in the most expedient manner possible. Equipment shutdown and chemical decontamination shall be considered a secondary objective to removing personnel from immediate life or injury threatening hazards. Decontamination should be achieved through the most expedient and practical means available once personnel are not longer at immediate risk. The assembly area for all personnel will be determined in the field by the SHSO. In all situations, when an on-site emergency results in evacuation of the Work Zone, personnel shall not reenter (1). The conditions resulting in the emergency have been corrected. (2). The hazards have been reassessed by the Site Safety Officer. (3). The Site Safety Plan has been reviewed by the SSO and Corporate Health and Safety Manager. SECTION 13: SPILL CONTROL PROCEDURES Any spills related to wet sediment and site water would cause minimal impacts. Solvents used during decontamination will be collected and stored for disposal back at the laboratory.

Project Plan August 27, 2000 Wilson Bay, NC Attachment B Page: B-2 • Wilson Bay Project Sampling Plan Preparing to Go to the Field An equipment checklist was created specific for the City of Jacksonville water aeration project in Wilson Bay. This checklist will be reviewed prior to travel to ensure all necessary equipment is available to perform the project objectives. The site-specific equipment list may be found in Appendix 1. Protocols and a sampling plan were prepared and data sheets created to capture the data necessary to evaluate the project objectives. Researchers were also contacted to arrange for the evaluation of data upon collection. British Columbia Resources Inventory Committee's Ambient Fresh Water and Effluent Sampling Manual was used as a guideline in developing the checklist and protocols. Before Sampling in the Field Each day the weather conditions will be observed. If conditions are inappropriate for safe boating and sampling at the sites, sampling will be postponed. Before departing from shore the checklist will be reviewed and a safety briefing will be given. The field staff will review the sampling plan and protocol. Locating the Sites in the Field All sampling stations will be accurately located using a global positioning system (with 1-5 m accuracy). Returning to the same locations is essential to monitor temporal changes in the water column and • sediments with confidence. Therefore, the station locations will be recorded with descriptions (the sample stations may be found in Table x and on the site map). Appendix 2 shows an example of a site identification guide sheet. Data included on each site identification guide sheet are latitudes, longitudes, sampling station identification #, and any distinguishing features. Field Notes/Observations Detailed field notes will be kept in a field logbook. The time of day, the weather conditions, along with observations of aquatic life, excessive algal growth, water traffic, odors, color, and foreign substances will be included in the log. Any deviations from standard protocols (e.g., samples taken from a different location due to safety or access considerations or procedures used that differ from those outlined here) will also be recorded in the field logbook. All of the field measurements (see appendix 3 for a sample site data sheet) will be entered directly into the field logbook at the time of collection. The information will be reentered into electronic form each evening after the day's fieldwork is completed. If additional samples are collected, but not exactly at an established station, a new site location description will be accurately recorded. This information and additional samples will prove useful during the interpretive aspects of the study. The field book is an important document and will be maintained for future use. Field Quality Assurance Field quality assurance is dependent on a systematic process that ensures a specified degree of confidence in the data collected for an environmental survey. The systematic process involves equipment maintenance, calibration, and sampling protocols. The quality of data generated depends on the ability to follow the process. Equipment will be calibrated following the manufacturer's instructions • prior to sampling. BATTELLE Use or disclosure of data appearing on this sheet is subject to the approval of the Battelle Project Manager. Project Plan August 27, 2000 Wilson Bay, NC Attachment B Page: B-3 . Sample Collection When collecting samples to evaluate at another location or laboratory, the sample's integrity must be maintained. Consequently, the field investigator must take the necessary precautions to protect samples from contamination and deterioration. The majority of the sampling that will be conducted during the Wilson Bay project is in situ field measurements (i.e., multi -parameter probe will be lowered into the water column). Therefore physical collection of water samples will be unnecessary. However sediment samples will be taken and will be preserved for later evaluation. The person at the bow (front) should always collect the samples. This is because the bow is the anchor point and, even in slow- moving water, the boat will drift so that the bow is upstream. This will prevent engine or boat contaminants from contaminating the sample. All containers used will be clean. Sampling Station Protocol Site Identification 1. Travel to sampling station location using the GPS. 2. Drop anchors to secure boat at location. 3. Record location information on a site identification data sheet. Include as much information to allow for certainty of return. It is critical that there be no deviation in location unless conditions at • the site (e.g., severe weather, physical changes of the site, etc.) pose a threat to the sampler's safety. In general, the near -shore sites detect those effects that are associated with influences such as groundwater and run-off. Deep stations provide information about the water column, such as conditions associated with stratification (depth profiles). Additionally, near -shore sites tend to provide information on a relatively short time scale (days or weeks). The deeper sites allow for documentation on a seasonal or longer time frame. Field Measurements Field measurements involve the use of specialized equipment. An equipment logbook will document instrument calibration, operation, and maintenance of the equipment used. This logbook must contain information about each instrument available to the sampling group in case equipment problems occur. Backup instrumentation will be available for the parameters required by the study — DO and SPI. All field data are to be recorded in the field logbook and reentered into electronic form at the end of a sampling day. • Clarity A Secchi disc will be used to measure water clarity in Wilson Bay. The Secchi disk is a weighted disk, 20 cm in diameter that is divided into black and white quadrants. The measurement is called the •extinction depth'. A "sludge judge" grab is another way to view the entire water column. Once the grab is brought to the surface it can be determined if a water -solids interface exists. BATTELLE Use or disclosure of data appearing on this sheet is subject to the approval of the Battelle Project Manager. Project Plan August 27, 2000 Wilson Bay, NC Attachment B Page: B-4 • Using a Secchi Disk 1. Lower the Secchi disk over the shaded side of the boat. 2. Record the depth at which the pattern of the disc is no longer observable. The disc should then be lowered beyond this depth to determine, when it ascends, the depth at which it reappears. Average the two depth readings to calculate the extinction depth. 3. Record the value in the field logbook along with the weather and water surface conditions (e.g., cloudy, sunny, windy, surface chop, etc.). Measurements should be to the nearest 0.1 meter. Note: Secchi disc readings should only be taken from 2 hours after dawn to 2 hours before dusk. During winter months, readings should only be taken between 10 A.M. and 2 P.M. Sunglasses should not be worn while taking the measurement. Using a Sludge Judge 1. Lower the sludge judge into the water vertically. 2. When it hits bottom, pull it up. 3. Measure the water -solids interface and record. 4. Record the appearance. • Stream Flow • Flow profiles of Wilson Bay water columns will be measured using current meters at multiple points along four transects. Velocities will be measured at 1' increments from surface and also at 2.5 inches from the bottom to establish velocity profile of the water column. Surface flow will be determined using a grapefruit. • Using a flow meter 1. Follow flow meter instructions as per the manufacturer's directions for storage, transportation, calibration, and use. 2. Lower flow meter into water to 1' depth (marked on device). 3. Time the number of counts and record the counts and time to achieve revolutions or record direct reading of velocity after it stabilizes. Using a floating object — grapefruit 1. Mark a grapefruit with the current identified sampling station number. 2. Place the marked grapefruit into the water and record the time and location of release. 3. Visually follow the grapefruit to establish when and where it should be retrieved. 4. Surface flow in Wilson Bay is minimal so care must be taken not to influence the flow when retrieving it. Upon retrieval identify the location using the GPS, record the time and location.

Project Plan August 27, 2000 Wilson Bay, NC Attachment B Page: B-5 • • Sediment Profile -Imaging • The sediment profile imager (SPI) is an upside down periscope designed to photograph a vertical profile of the first few inches of the top sediment layers. This device is used in shallow water environments (1-6 ft) to provide a picture of the first 8 inches of bottom sediment. The SPI body is aluminum square tubing (6 in x 6 in x 7 ft) with a glass viewing plate (5 in x 9 in) at the bottom of one of the sidewalls. A 450 mirror positioned opposite the glass window directs the profile image toward the opening at the top. An underwater light bulb (250K candlepower) inside the tubing provides light. All surfaces inside the tubing are covered with flat black paint to avoid light reflection problems. Distilled water is added to the SPI tube to add weight to counteract buoyancy as it is lowered into the water column. The distilled water also provides a good medium for transmission of the sediment profile image. An opening at the top end allows positioning of the camera lens to take photos of the reflected image of the sediments. 1. Connect the underwater light to a 12V battery. 2. One operator must fill the SPI tube with distilled water as another operator slowly lowers the SPI into the bay making a vertical insertion into the sediment. Note: care must be taken to ensure minimum disturbance of the sediment. The person lowering the unit can view the sediment profile (mirror's reflection) during SPI placement. 3. When a desired view of the sediment is obtained, a second operator places the camera lens in the top plate's opening, makes camera adjustments and secures a picture. 4. Record each sediment digital image ID (photo no.), its associated disk number, sampling station, GPS, date, and time on data sheets. • Multi -parameter Probe (pH, Conductivity, Turbidity, DO, Temperature, Depth, Salinity, TDS, Specific Gravity, and ORP) The Horiba U22 Water Quality Monitoring System will be used to monitor dissolved oxygen (DO) and temperature along with eight other characteristics in situ. The U-22 can be lowered through the water column and each parameter measured at a particular depth. This instrument has automatic temperature compensation for pH and DO. It also automatically standardizes the conductivity to the value at 25°C. The probe will be stored, transported, calibrated, and used in accordance with the manufacturer's instructions. To ensure that the probe does not come into direct contact with the sediment, a 1" diameter PVC pipe will be taped to the sensor housing and 2.5" of the PVC will extend past the sensor end. This way the PVC will hit the bottom before the sensor. Daily Calibration 1. Connect the probe to the instrument. 2. Prepare the DO and pH sensors. Replenish the pH probe with standard KCI solution as needed. Allow as few air bubbles as possible. 3. Connect the DO and pH sensors to the probe. Tighten with sensor spanner tool. 4. Rinse the sensor and calibration beaker with distilled water. 5. Measure Autocal solution in the calibration beaker to the mark and immerse sensor. Keep sensor vertical. 6. Press 'CAL' button when instrument is on and in the pH, conductivity, turbidity, DO, or depth is mode to place instrument into the auto calibration mode ('AUTO' and 'CAL' will appear). Now press the 'ENT' key. BATTELLE Use or disclosure of data appearing on this sheet is subject to the approval of the Battelle Project Manager. Project Plan August 27, 2000 Wilson Bay, NC Attachment B Page: B-6 i7. During calibration the 'DATA In' and the selected parameter[ ] will blink. As the item is calibrated the parameter [ ] will stay lit. Upon completion of all modes, 'End' will display. 8. Depress 'ENT' to set calibration. 9. Empty and neutralize the contents of the calibration beaker. Rinse the beaker and probe. 10. The sensor can be further calibrated manually with the Autocal II solution. Fill the calibration beaker to the fill line with the Autocal 11 solution. 11. Depress `CAL' button three times to enter manual calibration span mode. The Autocal II solution has a pH of 6.860 +/- 0.002, a turbidity of 100 NTU +/- 1.0%, and a conductivity of 53.7 ms/cm +/- 1.0%. 12. Adjust the parameter(s) at the sample temperature using the up and down arrow keys. Then depress the 'ENT' key. After the 'DATA IN' key stops blinking depress the 'ENT' key to set the calibration. 13. Now press the 'MEAS' key to place instrument into the measurement mode. Note: Refer to the operation manual for additional calibrations (zero, span, and troubleshooting. Record any discrepancies in the field logbook. Repeat this process before the end of the sampling day. Note: Samples should be at or near the temperature of the buffers used for calibration or the meter be equipped with a temperature compensation probe. Measuring Parameters 1. Tape the sensor housing to the 1" diameter PVC pipe. Allow 2.5" of PVC to extend past the • sensor end. 2. Rinse the probe using the squirt bottle of reagent grade de -ionized water and slowly immerse the probe vertically into water to the first mark (1' increments to bottom). 2. Depress 'MEAS' to switch between parameters (pH, conductivity, turbidity, DO, temperature, depth, salinity, TDS, specific gravity, oxidation reduction potential (ORP), and time). Record each reading at the depth. 3. Record the measurements at each depth to bottom and then again on the probe's ascent. • Note: Allow probe to equilibrate at each depth before recording values. When passing through a zone of rapid temperature or DO change the probe may take two to five minutes to equilibrate. Cleaning Equipment Equipment cleanness is an essential factor in ensuring that field data is accurate. All sampling devices (Secchi disk, lines, SPI, multiple -parameter sampler) will be thoroughly cleaned and scrubbed with de - ionized water after each sampling trip. This process should be followed by two or three rinses with de - ionized water. All shipping containers will be wiped free of dirt and rinsed with de -ionized water. The equipment will be stowed in a neat and tidy fashion. The boat and equipment will be returned in the same condition that it was received. It will be cleaned of aquatic plants and/or animals to prevent their spread to another body of water.

Davies 2 Bayview Drive Jacksonville, NC 28540 Dear Mrs. Davies: ,oONVILL, Caring ' Cogm�munity. HOME OF UNE MCAS In the process of cleaning up Wilson Bay, the City of Jacksonville will be experimenting with the use of three large aerators placed in the water approximately at the locations shown on the attached map. Photographs of the units are also enclosed. They will be powered by electrical cable running along the bottom of the bay. They will be anchored in the bay and will have an anchor light for nighttime visibility. This study will be conducted for approximately 90 days to prove the viability of these pieces of equipment. In order to receive the appropriate permissions from state environmental officials, we are required to notify adjacent property owner of this study. We are hoping that these units will prove themselves efficient in increasing the dissolved oxygen levels in the bottom of Wilson Bay and "jump start" the natural process that has stopped because of the lack of oxygen over the years. We are ultimately seeking funding from the U.S. Army Corps of Engineers to purchase units similar to these but have to prove their efficiency to the Corps before they will fund such a project.

We have now received all the return cards and certified receipts, and I am providing the originals to you. Battelle will be providing information about the power line. They intend to anchor the line after some tests at the site. They will be sending this letter directly to you, and I am sure as we mentioned, that they will work with anything that we need to do.

Putting Technology To Work 505 King Avenue Columbus, Ohio 43201-2693 Telephone (614) 424-6424 Facsimile (614) 4245263 The purpose of this letter is to document the consideration Battelle made to the expressed concerns regarding the #t6 AWG SEOW cables that will be deployed to power the Battelle InStreemTM units in Wilson Bay. Pursuant to our recently awarded contract with the City of Jacksonville, NC, we are tasked with siting and operating three InStreeni`rm units in Wilson Bay. The units will function to induce circulation within the Bay, de -stratify the dissolved oxygen in the water column, and establish an aerobic cap on the sediments. hi order to demonstrate the efficacy of this approach, data will be collected to substantiate anticipated results during a three- month period of performance. Single -Phase, 220 volt power for the InStreemTM systems will come via 600 feet of cable (-- 205 pounds) that will connect the systems to the shore -based electric power source. Battelle, supported by members of the Jacksonville City Engineer department, conducted a field test to determine if the cable required supplemental weighting to ensure that it is not prone to storm surge -induced movement. Roughly 40 meters of the cable were deployed into the water. Battelle scientists and engineers endeavored to examine and photograph the cable with a Sediment Profile Imager (SPI) device as it settled into anaerobic sludge/sediments in hopes of substantiating that the cable would be fully and safely seated in the sediments. Due to the turbidity resulting from the settling cable, images were not available. Since we were not able to substantiate that the cables self -seat in the sediment layer, Battelle proposes that anchors be used every 100 feet to ensure the cable is firmly in contact with the sediment layer and not available for surge or boat wake -induced movement. Further, Battelle will install color -coded buoys every 50 feet along the path of the submersed cable. The anchored buoys will not be attached to the cable but will serve only as a reminder that an underwater cable is present. It is our belief that this approach will ensure that the cable is stable, firmly embedded in the very soft sediment, and safely fixed for the three-month demonstration. Further, marking buoys and sipage will be installed that warn boaters not to drat; their anchors across the power lines.
