The project azea includes wetlands, and will require approval for a Nationwide Permit 38 for the Cleanup of Hazardous and Tozic Wastes. This letter serves as the Preconstruction Notification for this project.

Camp LeJeune is a U.S. Marine Corps Base, located in the southeastern coastal plain of North Carolina, in Onslow County, approximately 120 miles east of Raleigh and 50 miles north of Wilmington, near Jacksonville. The project boundary is within the greater G-10 Impact Area and titled Urban CAS, an azea of approximately 22 acres. URBAN CAS is a generally flat sandy azea with minimal grass and herbaceous vegetation. The area has been extensively impacted from explosives and is densely 111 W. 16"' Avenue, Third Floor Anchorage, Alaska 99501-5109 907-563-0013 Phone 907-563-6713 Fax A subsidiary of Bristol Bay Native Corporation Letter June 6, 2007 Page 2 littered with unexploded ordnance (UXO). See photographs in Appendix A. The Urban CAS area contains approximately 14.5 acres of wetlands for about 68 percent of the area (Figure 3). Description of the Proposed Project: The proposed project will remove range residue, UXO and explosives, and scrap from the surface, down to a depth of approximately 2 - 4 feet. The range residue will be inspected, classified and segregated, and all energetic items will be properly disposed of; range residue will be processed and demilitarized as required to ensure compliance with U.S. Department of Defense (4160.21M-1), and to permit direct consumption/recycling by an authorized metals recycler; recovered hazardous wastes (explosives related) will be manifested, transported, and disposed of at an approved Treatment, Storage, Disposal Facility and nonhazardous waste will be disposed of at an approved Class 3 Landfill. Operations will be scheduled from Friday through Monday to avoid conflict with range activities. The construction work will be conducted in four-day increments, utilizing the construction sequencing approach to minimize erosion potential. This approach will reduce the erosion and sedimentation occurring at the site since only a portion of the total site will be worked on at a time. On the last day of construction work, the work area will be leveled and covered with the cleaned, excavated material to facilitate the use of the range on Tuesday morning. Ultimately, the area will be reseeded with grass to further reduce erosion potential. The work in URBAN CAS is estimated to require 67 work days to complete the project. URBAN CAS is divided into two major sites: 1) the URBAN CAS Main Site, which comprises approximately 8 acres, and 2) the URBAN CAS Second Site, which comprises approximately 14 acres. The work sequence will follow the "Dig and Cover" method following a grid pattern, which will significantly reduce the amount of time that the soils are exposed to erosion processes. Once the surface debris and UXO have been cleared, additional soil will be removed in one-foot lifts. The Main Site area will be excavated to a total depth of 4 feet. The Second Site area will be excavated to a total depth of 2 feet. Each excavation will be systematically refilled, returned to original grade, and reseeded. An overgrown dirt road is located in the URBAN CAS Range, with a total area of approximately 2.66 acres. Metallic debris and UXO will also be removed from the road area. Surface UXO: • Walking through the area and removing metal debris and UXO by hand; Walking through the area, a metal detector will pass over the surface to locate metal and UXO laying just under the surface; and Metal and UXO located by the metal detector is removed by hand shovel or by using an excavator at the specific point of location. sr~5to~ Es Letter June 6, 2007 Page 3 UXO Excavation: • In some areas, minor depressions have been created by firing activities at the range. During rain events, these depressions have a tendency to fill with water, which will need to be drained prior to debris and UXO clearance activities commencing. This standing water will be removed from depressions using a pump and hose extending 50' - 100' away from the work site. A diffuser will be installed at the end of the hose in order to disperse the water uniformly. This is expected to occur primarily in the URBAN CAS Main Site; little to no water-filled depressions are known to occur at URBAN CAS Second Site, or in ranges G-8 and G-9. • Soils will be excavated in a series of lifts 6 - 12 inches following an approximate 100' x 100' grid pattern. • A 100' x 100' area will be excavated until metal detection instruments indicate no remaining metal in soil and then stop. Four feet is the deepest excavation anticipated. • Excavated material will be placed in a temporary/interim feed stockpile for a period of no more than one week. • Excavated soil will be run through a trommel to separate the UXO from the soil. • Sifted soil will be used to refill the excavation area. Soil will be spread evenly over the land surface to return it to the approximate original grade. • The excavated area will be reseeded. • Repeat the process throughout the area. See Figure 4, UXO Clearance Excavation Plan. Project Purpose: The purpose of the project is to make the URBAN CAS area safe for the installation of new targets suited for the current training requirements of the U.S. Marines. This includes: • The removal of UXO from URBAN CAS (22 acres); and • Eventually, the U.S. Marine Corps will install sea containers for use as targets in this area. This activity has not yet been awarded to a contractor or fully designed, and is, therefore, not included in this permit modification. The contractor who wins the award for this part of the project will apply for permits as needed. Environmental Effects: Environmental effects will be minimal. There is minimal vegetation present at the site to be disturbed. It is primarily impacted sandy soils. The area is being refilled, regraded, and revegetated once the ordnances are removed from the site. The following erosion and sedimentation best management practices, and control measures and devices, will be used on this project: Bristol ~aE=~LLO~ Letter June 6, 2007 Page 4 • UXO excavation will be done in a 100 m x 100 m grid pattern to minimize the area of disturbance at any one point in time; • Each grid section will be refilled to original grade before excavation of the next grid section; • The overall project site will be graded in preparation for future construction plans (to be addressed under separate permit when the work contract is awarded); and • The area will be reseeded as quickly as practicable, and within a maximum of 21 days after final contouring, to encourage reestablishment of ground cover to minimize erosion. Delineations: The project area has been used as a target impact area for over 50 years. The area is highly impacted and strewn with missiles, hand grenades, bombs, and other munitions, including UXOs. For this reason, it is unsafe to conduct delineations within this area. The National Wetlands Inventory (NWI) and National Cooperative Soil Survey have been used to determine the presence of wetlands in this area. Field observations indicate that the actual jurisdictional wetlands in the area are significantly less than indicated in the NWI. However, the more conservative acreage delineated by the NWI and soils map will be used in lieu of an on-site delineation because of the safety issues mentioned above. See Figures 3 and 5 and photographs in Appendix A. Endangered or Threatened Species: Camp LeJeune is home to the federally listed endangered red-cockaded woodpecker (Picoides borealis). Urban CAS is a previously cleared area and is not affected by the Camp LeJeune Endangered Species Management Plan. Historic Properties: There are no historic properties in this area. The project area has been heavily impacted by missile and bombing activity for over 50 years.

Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It maybe useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. The project is the removal of hazardous materials (unexploded ordnance -hand grenades, missiles, and bombs) which are scattered throughout the entire area, including all wetlands within the area. Impacts are minimized through a phased excavation in 100 m blocks that are refilled within approximately 4-5 days in order to minimize the area and duration of disturbance at any one time. The entire area will be revegetated. VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USAGE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USAGE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strm ~ide.html.

Discuss Stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. If percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed impervious level. There are no impervious surfaces presently or proposed at this site. Small amounts of water may need to be pumped out of bomb impact pits -this water will be discharged to the surrounding area through a diffuser to minimize runoff. All runoff will be absorbed into the surrounding soils. There is no nearby waterbody. XII. Sewage Disposal (required by DWQ) Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility. Page 8 of 9 Small amounts of water may need to be pumped out of bomb impact pits -this water will be discharged to the surrounding area through a diffuser to minimize runoff. All runoff will be absorbed into the surrounding soils. There is no nearby waterbody. XIII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules? Yes ^ No Is this anafter-the-fact permit application? Yes ^ No XIV. Cumulative Impacts (required by DWQ) Will this project (based on past and reasonably anticipated future impacts) result in additional development, which could impact nearby downstream water quality? Yes ^ No If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with the most recent North Carolina Division of Water Quality policy posted on our website at http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: The proiect may be followed up with the installation of sea containers as targets suited to meet the current training requirements of the Marine Corns. The continuation of the practice of using various obiects at this site for target practice is not anticipated to impacted any waterbodies. XV. Other Circumstances (Optional): It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits. However, an applicant may choose to list constraints associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control).
