H. Grant and Eugene B . Grant, Jr, agents for the land owner/developer, Henry Long, is hereby submitting notice of a proposal to use coal combustion by-product as structural fill for a site, designated as Arthur's Creek, as described in the enclosed Notification and Siting documents, and shown on the attached construction plans. The purpose of the project is to provide a site ready for development, for which office buildings, and associated parking lot and access road can be constructed. This will allow for commercial develop in this designated "growth area" as intended by Northampton County. The structural fill project is anticipated to start on May 26, 2004, and the anticipated end date is December 31, 2007. The volumes of the flyash and bottom are indicated in the enclosed documents. Eugene B. Grant of The Plumbline Corporation is the NC registered engineer, Please call either of us at the above referenced phone number if you have any questions. Sincerely, ILI -z A Henry R.H.

This area includes a Lowe's distribution warehouse that was completed two years ago. This purpose of the project is to utilize coal combustion by-products as structural fill to construct an Industrial/Commercial site for a private developer. The end -use of the site will be for office buildings, thus, increasing the development area as intended by the County. The existing zoning for the site, as determined by Northampton County, is agricultural (listed as AG). An application will be prepared and submitted to the County upon completion of the structural fill project to rezone the site to allow for construction of the buildings. The structural fill project is allowed under the existing zoning. The structural fill building site will consist of 21.7 acres, of the 42.6 acre property. This area has been logged of trees and there is no standing timber. Upon completion of the intended project, the Developer will receive a prime building site complete with a foot print for an office building and two (2) proposed auxiliary buildings, a parking lot, and an access road. The estimated schedule to complete the structural fill project is 42 months. A detailed construction schedule is included in the enclosed Erosion and Sedimentation Control Plan for the project. The estimated value of the completed building site is approximately $205,000, The existing value is currently about $21,000, The project will allow for economic development and growth, increase the tax base, and provide high end jobs to a poor county. 'This project does not involve the Department of Transportation. Estimated Volume: The estimated volume of fill is approximately 550,000 cubic yards. The project building site will take approximately 21.7 acres of the entire 42.6 acre site. TCLP Test Results: The results of the March 2004 analysis for flyash and bottom ash for both units I and 11 are attached. Jlesd/RVP/Notification for Arthur's Creek Projectl doe 1 Matement by Owner: A signed and dated statement by the land owner is attached. In addition, a signed and dated statement by the agent of the land owner is also attached. Generator In.

SITING( 1704) Jurisdictional Wetlands: To ensure this requirement is met, an engineer from the U.S. Army Corps of Engineers was contacted, visited the site, and delineated the wetlands. As noted on the drawings, the structural fill will not be placed within 50 horizontal feet of jurisdictional wetland. Thus, the wetlands will not be impacted by the project. A letter from the Corps verifying this determination is enclosed. Perennial StreamlSurface Water. The engineer from the Corps also delineated streams and surface waters. These are shown on the drawings. The structural fill will not be placed within 50 horizontal feet of a surface water body, thus, the surface water body will not be impacted by the project. A letter from the Corps verifying this determination is enclosed. However, to accommodate access to the building site after the fill construction is completed, a perennial stream will need to be crossed. Therefore, a Pre Construction Notice (PCN) has been prepared and submitted to the U. S. Army Corps of Engineers for review and processing. It is believed the stream disturbance due to the road crossing will be approved under a Nationwide 1.4 Permit. Another route, which does not impact perennial steams and is not within 50 horizontal feet of the stream, is currently available for access to the structural fill project area. Jlesd/RVP/Notification for Arthur's Creek Projectldoc 1) Groundwater Table: To ensure this requirement is met, a number of test wells were installed to observe any fluctuations in the water table over the time period since January. The locations are shown on the drawings, and the results and details are enclosed. The data results demonstrate that the coal combustion by-products will not be placed within 2 feet of the <.seeasonal high groundwater table. The soils report, included as part of the Erosion and Sedimentation Control Plan, shows the soil types found on the site. The area is well drained. Drinking Water: As stated above, this area is agricultural, with little development on the adjacent properties. As indicated on the drawings, there are no drinking water sources within 100 horizontal feet of the intended structural fill area. The future building(s) is going to be serviced by the County Water system, a water tap will be provided at the road as best determined by the Northampton County Water Department. a �''Mlfi�_' M The subject project fill area, as well as the entire property site, is completely out of the I 00-year flood zone as shown on the enclosed FEMA flood map. The flood elevations are also noted on the drawings. Property Boundary: The project fill area is located well within the property. It is more than 25 feet from any property boundary. The boundary information is depicted on the drawings. Bedrock Outcrop: A bedrock outcrop is not located on the property site, thus, the structural fill area is not located within 25 feet of a bedrock outcrop. All criteria listed under this section of the regulations will be met throughout the design, construction and operation of the structural fill project.

Compaction re- quirements are the same as those for the embankment. Keep the trench dry during backfilling and compaction operations. 3. Embankment —Take rill material from the approved am shown on the plans, It should be clean mineral soil, free of roots, woody vegetation, rocks, and other objectionable material. Scarify areas on which fill is to be placed before placing fill. The fill material must contain sufficient moisture so it can be formed by hand into a ball without crumbling. If water can be squeezed out of the ball, it is too wet for proper compaction. Place fill material in 6 to 8-inch continuouslayers over the entire length of the fill area and then compact it. Corn- 6.61.6 paction maybe obtained by routing the construction hauling equipirient over the fill so that the entire surface of each layer is tcaversed, by at least one wheel or tread track of the heavy equipment, or a compactor may be used. Construct the embankment 10 an elevation 10% higher than the design height to allow for set- tling. 4. Conduit spillways ---Securely attach the riser to the barrel or barrel stub to make a watertight structural connection. Secure all connections between barrel sections by approved watertight assemblies. ' Place the barrel and riser on a firm, smooth foundation of impervious roil.Do not use pervious material such as sand, gravel, or crushed stone as backfill around the pipe or anti -seep collars. Place the fill material around the pipe spillway in 4-inch layers and compact it under and around the pipe to at least the same density as the adjacent embank- ment. Care must be taken not to raise the pipe from firm contact with its foundation when compacting under the pipe haunches. Place a minimum depthof 2 ft of hand-coull)Wted backfill Over the Pif)4'- spillway before crossing itwith consummori equipmeaL Anchor the riser in place by con- crete or other satisfactory means to prevent flotation. In no case should the pipe Conduit be installed by cutting a trench through the dam after the embankment is complete. '5. Emergency spiUway—Install the emergency spillway in undisturbed soil. The achiev ement of planned elevations, gra&, design width, mid eauaum and exit channel slopes are critical to the successful operation of the emergency spillway. 6. Inlets —Discharge water into the, basin in a manner to prevent erosion. Use diversions with outlet protection to divertsediment-laden water to the upper end of the pool area to improve basin trap efficiency (References:Runoff Control Measures and Outlet Protection). 7. Erosion control—COnsuuct the structure so that the disturbed area is mini- mized. Dived surface water away from bare areas. Complete the embankment before the area is cleared. Stabilize the emergency spillway embankment and all other disturbed areas above the crest of the principal spillway immediately after construction (References: Surface Stabilization). S. Safety —,Sediment basins may attract children and can be dangerous. Avoid steep side slopes, and fence and mark basins with warning signs if trespassing is likely. Follow all state and local requirements. Maintenance Check sedimentbasins after periods of significantrunoff. Remove sediment and restore the basin to its original dimensions when sediment accumulates to one- half the design depth. Check the embankment, spillways, and outlet for erosion damage, and inspect the embankment for piping and settlement. Make all necessary repairs im- mediately, Remove all wish and other debris from the riser and pool area. 6.61.7 Figure 6.62a installation detail of a sediment fence_ Compactedfill Backfill min 8" thick layer of gravel Filter fabric A, 8 wire 4 Practice Standards and Specifications CONSTRUCTION 1. Construct the sediment barrier of standard strength or extra strength synthetic filter fabrics. 2. Ensure that the height of the sediment fence does not exceed 18 inches above the ground surface. (Higher fences may impound volumes of water sufficient to cause failure of the structure.) 3. Construct the filw fabric from a continuous roll cut to the length of the bar- rier to avoid joints. When joints are necessary, securely fasten the filter cloth only at a support post with overlap to the next post. 4. Support standard strength filter fabric by wire mesh fastened securely to the upslope side of the posts using heavy duty wire staples at least I inch long, or tie wires. Extend the wire mesh support to the bottom of the trench. 5. When a wire mesh support fence is used, space posts a maximum of 8 ft apart. Supportposts should be driven securely into the ground to a minimum of 18 in- ches. 6. Extra strength filter fabric with 6-ft post sparing does not require wire mesh support fence. staple or wire the filter fabric directly to posts. 7. Excavate a trench approximately 4 inches wide and 8 inches deep along the proposed line of posts and upslope from the barrier (Figure 6.62a). S. Backfill the trench with compacted soil or gravel placed over the filter fabric. 9. Do not attach filter fabric to existing trees. Maintenance Inspect sediment fences at least once a week and after each rainfall. Make any required repairs immediately. Should the fabric of a sediment fence collapse, tear, decompose or become in- effective, replace it promptly. Replace burlap every 60 days. Remove sediment deposits as necessary to provide adequate storage volume for the next rain and to reduce pressure on the fence. Take care to avoid undennin- ing the fence during cleanout. Remove all fencing materials and unstable, sediment deposits and bring the mra to grade and stabilize it after the contributing drainage area has been properly stabilized. 6.62.3 I Trapezoidal Riprap Channel A Filter layer, gravel or fabric C> rq Piz 7-<' e T" o'-/ r,>E-LOW CAHANNe�-- 4XYTLa-r ANP WU�,eN <--t�A�NSL -M FOR V4 -ro ANr.> Au- -3viN-r',5 ' -T-6 OVap-LAP 4', MiNIMOM Of= 1.0 K"PKAi, chi e'er I�IrgAP -1-0 5a WrT14 V---XV5T1N6j 6VaJP-f-AV4_ liT- 729 12.0' VOWN-,Tr-eAM.

This gently sloping and strongly sloping, well drained soil is on uplands, generally in the northern part of the county. Individual areas commonly are long and narrow and range from 10 to 30 acres in size. Some areas are as large as 100 acres. Typically, the surface layer is grayish brown loamy sand 9 inches thick. The subsurface layer is pate brown and light yellowish brown loamy sand 24 inches thick. The subsoil extends to a depth of 65 inches. The upper part is yellowish brown sandy clay loam with strong brown mottles. The next part is yellowish brown sandy clay loam with light brownish gray, strong brown, and red mottles. The lower part Is mottled yellowish brown, strong brown, and light brownish gray sandy clay loam. Permeability is moderate, and available water capacity is low. The hazard of water erosion Is moderate. The soil Is subject to soil blowing` and the leaching of nutrients. The seasonal high water table is at a depth of 3.5 to 5.0 feet. Included with this soil in mapping are a few small areas of the well drained Norfolk soils, which are Soil survey intermingled with areas of the Bonneau soil throughout the map unit. Also included are a few areas that are more sandy throughout and a few areas that have more clay than is typical for the Bonneau soil. Included soils make up about 25 percent Of the map unit. Most of the acreage of the Bonneau soil is wooded. A few areas are used for cultivated crops. This soil generally is not used for cultivated crops. The hazard of erosion, the slope, soil blowing, and the leaching of plant nutrients are the main limitations. Com, soybeans, and small grain are the major Crops grown in areas that have been cleared of trees. Conservation practices, such as no -fill planting, field borders, and crop residue management, conserve Soil moisture and help to control water erosion and soil blowing. Pasture forages, such as coastal betmudagrass and bahiagrass, grow well on this soil. Establishing a stand is difficult because of the slope and the hazard of erosion. The major overstory trees grown are loblolly pine, red maple, hickory, sweetgum, black cherry, American beech, southern red oak, white oak, and post oak. The understory vegetation consists mainly of flowering dogwood, sassafras, American holly, sourwood, and southern waxmyrtle. The thick, sandy surface layer is a moderate limitation affecting the use of equipment. The thick, sandy surface layer and low available water capacity are moderate limitations affecting seedling mortality. The slope is the main limitation on sites for dwellings, commercial buildings, local roads and streets, and lawns and landscaping. Special design may be needed to overcome this limitation.

The subsoil is 29 inches thick. The upper part is strong brawn clay with red mottles. The lower Part is strong brown clay loam with reddish yellow mottles and Pockets of saprolite. The underlying material to a depth of 60 inches is multicolored clay loam or sandy loam saprolite. Permeability and available water capacity are moderate. The shrink -swell Potential also is moderate. The hazard of erasion is severe in areas where the soil has been cleared of trees. The seasonal nigh water table is at a depth of more than 6 feet. Included with this sail in mapping are a few areas of the red Pacoiet soils in landscape positions similar to 46 those of the Wedowee soil. Also included are some shallow soils and small outcroppings of rock, generally at the base of the steeper slopes. Inclusions make up about 20 percent of the reap unit. The Wedowee soil is used mainly as woodland, A few small areas are used as pasture. The main limitations affecting cultivated crops are the slope and the severe hazard of erosion. The slope also is a limitation in areas used as pasture. Proper pasture management erasures an adequate protective cover of vegetation. The major overstory trees are loblolly pine, southern red oak, white oak, yellow -poplar, and hickory. The understory vegetation consists mainly of flowering dogwood, American holly, and sourwood. The slope and the effects of past erosion are moderate limitations affecting woodland use and management. The slope also limits the use of equipment. The hazard of further erosion is accelerated along logging roads and in areas that have been cleared of trees. They slope, the shrink -swell potential, and the clayey, moderately permeable subsoil are limitations on sites for dwellings, commercial buildings, lawns and landscaping, shallow excavations, and septic tank absorption fields. special design may be needed to overcome these limitations. Low strength is a limitation on sites for local roads and streets. The slop; is a moderate limitation in areas used for camping and picnicking and a severe limitation in areas used for playgrounds.

The dominant overstory trees are southern red oak, sweetgum, loblolly pine, hickory, and American beech. + The understory vegetation consists mainly of flowering dogwood, American holly, sourwood, red maple, and sassafras. The slope is a moderate limitation affecting the erosion hazard and the use of equipment for woodland use and management. A cable yarding logging system results in less damage to the soil and reduces the limitation for the use of equipment. Maintaining a cover of vegetation and specially designing logging roads help to control erosion. The slope is a severe limitation on sites for dwellings, commercial buildings, local roads and streets, lawns and landscaping, shallow excavations, and septic tank absorption fields.
