Mr. John Dorney of the North Carolina Division of Water Quality, Chambers has modified the initial draft Wetland 1 itiwion Plan, (which was submitted to you -along with a.copy of our January.12, 1.999 letter to the Corps) to include both stream, mitigation and`wetland mitigation. Accordingly, please find enclosed a copy of the current Stream and Wetland Mitigation Plan dated March 1999 for the above -referenced project prepared by A1mes & Associates, Inc. As you may recall, construction of the proposed facility will result in the unavoidable fill of 0.49 acres of jurisdictional wetlands including 1,084 feet of low -quality stream channels. To compensate for these impacts, Chambers will conduct the on -site mitigation described below in lieu of making payments into the Wetlands Restoration Fund or providing other forms of off site mitigation: Wetlands Miti ation. Chambers will compensate for wetlands impacted by construction activities at no less than a 2:1 ratio. Thus, at least 0.98 acres of wetlands will be created. In addition, the replacement wetlands will provide a more diverse habitat (vegetation and wildlife) than that currently available. Streams Mitigation. Chambers will restore a highly eroded, incised streambed with little to no bottom substrate into a more natural configuration that will limit erosion and provide increased habitat for wildlife and benthic macroinvertebrates.

The FWS' artd NCWRC's' comments relate tb the Corps' Public Notice.dated October 22, 1998 (the "Public Notice") regarding Chambers' application for a permit to discharge fill. material at tine proposed Anson County Solid Waste Management Facility (the "Site"). As requested; this letter responds to FWS' and NCWRC's comments. For your conveniences we are forwarding copies of our responses with attachments directly to these agencies. Although there is some overlap between the two responses, we have included complete responses to each agency's comments to prevent any confusion. As you evaluate FWS' and NC C's comments and our responses, please consider the following points. First, many of the comments relate to the operation of the proposed facility rather than the discharge of fill material into wetland areas. 'These types of comments are outside the scope of the wetlands permitting process and do not require consideration by the Corps. As discussed, interested parties such as FWS and NCWRC will have the opportunity to comment on operational issues related to the proposed facility during the public comment period on the draft Permit to Construct to be issued by the North Carolina Division of WasteManagement's Solid Waste Section (the "Solid Taste Section"). In an attempt to expedite the overall permitting process for the facility, we have responded to all of FWS' and NCWItC's comments. However, our willingness to (ally respond does not mean that Chambers agrees that all of their comments are entitled to the Carps' consideration during the wetlands permitting process. Second, NCWRC's comments suggest that the wetlands permit not be issued until the proposed facility and its potential impacts are discussed in a comprehensive environmental document. Applicable laws and regulations do not require an environmental document for this project because it does not involve public monies or public lands. Although no formal January 12, 1999 Page I environmental document has been prepared, Chambers has thoroughly evaluated the Site to demonstrate that the proposed facility satisfies the detailed siting, design and operational requirements in the Solid Waste Section's regulations. Much of the. data obtained. during this six - year process is simfiar to that which would be in a formal environmental'document Again, to expedite the permitting process, our responses include the information that NCWRC requested to be addressed in an environmental document for the proposed facility even though many of these. requests are outside the scope of the wetlands permitting process. We believe that the. fallowing responses address the comments raised by F S and NC RC regarding the fill`activities to be authorized by the Carps' wetlands permit: Chambers sincerely appreciates the Corps' efforts to expedite the wetlands permittinggrocess.

Potential Impacts.to Wetlands and eater i2ualift The. Site includes approximately 1,20.0 acres west of Wadesboro, North Carolina located adjacent to and north of Highway 74 The delineation conducted at the Site identified approxirnateiy 310 acres of wetlands, consisting of floodplain (including forested and marsh areas), intermittent stre,a.rn courses, headwater seeps, and excavated, ditched or drained wetlands. Chambers proposes to place clean fill in approximately 1.6 acres of wetland areas (only 0.05% of the total wetland acreage on the Site), including 1.1 acres of non -stream ' wetlands. The 3,730 linear feet identified in the Public Notice are low quality, drainage channels that historically have been impacted by fanning and timbering activities. These storrnwater channels carry surface water for a watershed of approximately 13 5 acres. Eased on the calculations in Attachment 2, these channels should be classified as above -headwater according to 33 CFR 330.2(d). There will be no landfill activities of any kind in the remainder of the wetland and upland areas in the bluffs and floodplain areas of Brown Creel- and Pinch Gut Creels. A design drawing showing the final landfill development is enclosed as Attachment 3. The: proposed: facility is designed to avoid potential impacts to water quality. Chan, bens' site -specific; Erosion and Sedimentati€ n (E&S) Plans have been approved by the Land Quality Section of Do's Fayetteville R4onal office. " The approved Plans address the initial phase of the proposed work north of the railroad' tracks (73 acres) and south of the.railroad tracks (14.3 acres). We have enclosed copies of theE&S Plans and approvals (Attachments 4; 5; 6 and 7): Chambers will be required to obtain additional D approvals for any work beyond that reflected in these initial plans and :approvals. The Solid Waste Section's regulations require that the proposed facility include storrnwater and sedimentation control measures sufficient to control surface water run-off and rum -on generated from a 24-hour, 25-year storm event. 'to comply with those requirements, stonnwater will be directed to sedimentation/retention basins allowing for a controlled discharge. The design and maintenance protocol for the facility's storrnwater and sediment management system are described in detail the E&S Plans and in Sections 2.1.10, 2.2.1.5, 4.3.7, 4.4.1.2, 4.4.2.3 and 4.4.3.2 and depicted on drags E-6, E-13 and E-14 of the Permit to Construct Application. Copies of these sections and drawings are enclosed as Attachment 8. Leachate will have no impact on water quality at the Site as it will be discharged to the local wastewater treatment facility. To ensure that no unanticipated impacts to water quality occur, the Permit to Construct Application also contains a Water Quaiity Monitoring Plan for the Site as required by the Solid Waste Section regulations. 2. Pee Dee National Wildlife Refuge Consistent with the Solid Waste Section's siting, design and operational requirements, the facility is engineered to minimize impacts on the surrounding community and environment. Access to the facility will be from existing Highway 74, a major thoroughfare with sufficient January 12, 1999 Page 3 capacity to handle truck traffic to the landfill. No off -site infrastructure will be constructed in connection with the facility. With respect to nuisance wildlife, the Solid Waste Section's regulations require the facility to control and/or prevent sin -site populations of disease vectors and "other" animals using techniques appropriate for the protection of human health and the environment. Controls at the Si$e w;11 include daily cover manageme t, litter control and adequate fencing. These procedures are; described in Sections 4 3.4.4 and 4.41.5, of the Permit to Construct Application (Attachment'9). .3. Sufficiency of Weilan& Mitigation: : e have enclosed a copy of the draft Wetlands Mstigation Plan, dated May 1998, prepared by Alrnes & Associates, Inc. (the "Mitigation Plan")(Attachment 10). As Section 4.0 of the litigation Flan indicates,. the proposed. project will impact 1.1 acres of wetlands and 3,730 linear feet (which equates to approximately 0. 5 acres) of prim y low quality, d wage, channels that historically have been affected by human activities associated with farm and timbering activities. These channels carry surface water during periods of, and subsequent to, wet weather. Based on the criteria in North Carolina's New Wetland Rules: Supplemental infcrrnation - Field. location of streams., ditches and ponding„ dated February 10, 1997 (the "Guidance"), most of the imp acted areas are classified as.:.storznwater.. channels ratherthan .inteamittent streams. In a March .. . 12, 1998 'Mernorandurn documeritin� his site visit (Attachment is y� den Averitte'ofthe North Carolina Division of Water Quality's (" 1, WQ") Fayetteville Regional �ffice questioned whether any of these channels should be classifiedas intermittent streanns and concluded that the stoirr water channels provide very limited water quality fozic*,ioi . As. described in the Mitigation Plan; Chamberswill. create.3.2 acres. of high -quality, permanently inundated wetlands to mitigate for the fill of 1.6 acres of marginally functional, seasonally saturated wetlands and wet weather channels on the Site. Based on the specific conditions at the Site and observations of DWQ staff, in -kind mitigation of the channels would not afford any discernible benefits. Mather, the proposed mitigation area will afford a greater degree of wetland functions and increased wildlife habitat, will provide better protection of water duality at the Site and will better satisfy the designated wetland uses outlined in state 'regulations than other nutigation alternatives. As FWS suggested, the Mitigation Plan will be modified -to provide for monitoring of the mitigation site for fide years. 4. Reguest for Conservation Easement Although there is no legal requirement to impose a conservation easement on any portion of the Site, Chambers is willing to discuss the passibility of granting a conservation easement for areas along Pinch Gut Creels and Brown Creels and/or the wetlands mitigation site. These discussions, however, should not delay issuance of the wetlands permit. Significant protections will already exist since much of the area that FS requested to be covered by a conservation easement is located in the buffer areas on the Site and no landfill activities of any kind will take place in the remaining floodplains. January 12, 1999 Page 4 Chambers' Respomve to North, Carolina Mildlife Resources Commission 1.5 Comment Memorandum dated November 20,1998 (Attachment 12) 1. Descri tio®n of Fish and Wildlife Resources/Federally or State. Designated Threatened, Endangered or Special Co.nees n Species,. . As part of the Site Suitability Study required by.the Solid Waste Section's regulations, Chambers retained Carlow & Associates to prepare a Wetlands Delineation and Protected Species Survey of a Proposed lie 'onai Landfill Site Anson CougV, North Carolina (the "Wetlands Delineation and Protected Species Survey")(Attachment 13). The Wetlands Delineation -and Protected Species Survey provides detailed descriptions of the ecological communities on the Site and concludes that the project will not impact any federal or state designated threatened; endangered orspe ialconcern species. As documented in a letter dated December 16, 1996.(Attachment 14), the N rth Carolina. Division of Parks & Recreatip agrees ... with the Wetlands Delineation and Protected' Species, Survey's," findings that there are unlikely to be impacts on any federal or state listed species of plants and animals" and that "the area to be occupied by the landfill itself has little significance as a natural area,." As documented in two letters, the United States Fish and Wildlife Service has concluded that the project will have no effect on listed species (Attachments 1 and 15). 2. OwnerAip ®f Hi h Quality Habitat Alon-Browrn Creek Chambers owns the referenced areas along the eastern portion of Brown. Creek and the western portion of Pinch Gut Creek. The high quality wetlands adjacent.to the creeks will be included in the undeveloped buffer areas and no landfill activities of any. kind will take place; in the remaining floodplains. A design draining shoring the final landfill development is enclosed as Attachment 3. Although there is no legal requirement to impose a conservation easement on any portion Of the Site, Chambers is willing to discuss the possibility of granting 4.conservation easement for areas along Pinch Gut Creek and Brown Creek and/or the wetlands mitigation site.. 'These discussions, however, should not delay issuance of the wetlands permit. Significant protections already will be in place since rnuch of the area: that NCWRC requested to be covered by a conservation easement is located in the buffer areas on the Site and no landfill aedvities of any kind vain take place in the remaining floodplains. 3. Wetlands Mitization Plan We have enclosed a copy of the draft Wetlands NEti ation Plart dated May 1998, prepared by Almes & Associates, Inc. (the "mitigation Plan") as Attachment 10. Section 6.0 of the NEtigation Plan provides a detailed description of the proposed mitigation site. The Wetlands Delineation and Protected Species Survey (Attachment 13) also discusses the wetland cornumunities on the Site. January 12, 1999 Page 5 4. Imnact on- Fee Dee Wildlife Refuge Consistent.with the Solid Waste Section's siting, design end: operational requirements, the facility is engineered to minimize impacts on the surrounding community a.nd environment Access to the facility will be from existing Tfighway 74, a major thoroughfare with sufficient. capacity to handle truck traffic to the landfill. No off -site infrastructure will be constructed in connection with the facility. With respect to. nuisance wildlife, the Solid. Waste Section's regulations require the facility to -.control and/or prevent on -site populations of diseasei vectors and "other." animals using techniques appropriate for the protection of human health and the environment. Controls at the Site will include daily cover management, litter control and adequate fencing. These procedures are described<in Sections 4 3 4,4.and 4A4 5 of the Permit to. Construct Application_ (Attachment 9): Section 4.0 of the Mitigation Plan provides a detailed description of the°.plant:species in the wetland areas to be impacted. by the discharge of fill materials. °6. Stream Mitigation As Section 4:0 of the Ntigation Plan indicates;, the proposed project will impact 1.1 acres of wetlands and 373 Q linear feet'(which equates to approximately 0.5 acres) of primarily low quality, drainage channels that historically have been affected by human activitiesassociated,with. farm. and timbering activities. ' These channels carry surface water during periods of and subsequent to, wet weather. Based on the criteria in North Carolina's New Wetland Rules: Sul2plemental information -Field location of streams ditches and pondin dated February 10, 1997 (the "Guidance"), most of the impacted areas should be classified' as stormwater channels rather than intermittent streams. In a March 12, 1998 memora_ndum documenting his site visit (Attachment 11), Ken Averitte of the North Carolina Division of'Water ` Quality's ("i Wq ): Fayetteville Regional Office questioned whether any of these channels should be classified as intermittent streams and concluded that the stonnwater channels provide very limited water quality functions. As described in the Mitigation Plan; Chambers will create 3.2 acres of high -quality, permanently inundated wetlands to mitigate for the fill of 1.6 acres of marginally functional, seasonally saturated wetlands and wet weather channels on the Site. Based on the specific conditions at the Site and observations of DWQ staff in -land mitigation of the channels would not afford any discernible benefits. We believe that the proposed mitigation area will afford a greater degree of wetland functions, will provide better protection of water quality at the Site and will better satisfy the designated wetland uses outlined in state regulations than other mitigation alternatives. In addition the Mitigation Plan will be modified to provide for monitoring of the mitigation site for five years. Jununry 12, 1999 Page 6 7. Erosion and Sedimentation Control Chambers' site -specific Erosion and Sedimentation (E&.S)>Plans have been apprbve.d.by the Land Quality Section ofDENR's Fayetteville Regional office. The approved Plans address the initial phase of proposed work north. of the railroad tracks (73 acres) and south of the. railroad tracks (14.3 acres). We have enclosed copies. ofthe.E&iS Plans and approvals (Attachments 4, 51.6 and 7) Chambers,w .be reguired`to obtain'a: itionalDENR'approvals for any work beyond that reflected in these initial plans and approvals: The Solid Waste Section's regulations require that the proposed facility include stormwater and sedimentation control measures sufficient to control surface water run -tiff and run-on generated from a 24-hour, 25-year storm event. To comply with those requirements, stornawater will be directed to sedimentation/retention basins allowing for a controlled discharge. The design and maintenance protocol for the facility's stormwater and sediment management system are described in detail the E&zS Plans and in Sections 2.1.10, 2.2.1.5, 4.3.7, 4.4.2.3 and 4.4.12. and depicted on drawings -E 6, E-13 and E14 of the.Permit to: Construct Application. Copies of these sections and drawings are enclosed as Attachment V. 3. Leachate and Storrnwater Management Leachate from the facility will be collected and pumped directly to the sewer system for proper treatment and disposal at the Anson County's wastewater treatment facility. The facility's leachate collection system is described in detail in Section 1.2.4 of the Permit to Construct. Application. A copy of this section is enclosed as Attachment 16. Stormwater management is described in Response 47. 9. Upland Wildlife Habitat Section 3.3.1 of the Wetlands Delineation and Protected Species Survey (Attachment 13) provides a detailed description of the upland communities on the Site. Figure 2 in the Wettlands Delineation and Protected Species Survey depicts the uplands communities on the Site. 10. Impact on Wildlife Habitats The activities to be authorized by the wetlands permit will only impact 1.6 acres (approximately 0.5%) of approximately 310 acres of wetland communities on the Site. The remainder of the project is located in a loblolly pine plantation area that has been harvested and planted since 1967. As the Wetlands Delineation and Protected Species Survey notes, there is very little natural or undisturbed upland habitat on the Site. The North Carolina Division of _- January 12, 1999 Page 7 Parks & Recreation agrees that "the area to be occupied by the landfill itself has little significance as a natural area." See Attachment 14, 11. Reduction of Impacts As described in the Mitigation Plan, Chambers will create 3.2 acres of new high quality wetlands on the Site. This compensates for the wetlands to be impacted by the fill activities at a 2:1 ratio. The only high quality habitat areas on the Site (other wetland areas, bluffs and ravines along Brown Creek and Pinch (gut Creek) will be included in the undeveloped buffer areas. In.a letter dated Septeanber .1..1998 we provided inf®rdiatidn to the .Cbrps on the lack of practicable alternatives to placing fill-in the wetland areas (Attachment 17). Based on this information, the Corps concluded in the Public Notice that "the proposed project appears to be the least environmentally damaging practicable alternative." 5anuary 12, 1999 page 8 Parks & Recreation agrees that "the area to be occupied by the landfill itself has little significance as a natural area." See Attachment .14. 11. Reduction of ll lRacts As described in the 1M igation flan, Chambers will create 3.2 acres of new high quality wetlands on the Site. This connipegasates for the wetlands to be irnpacted by the fill act."w'-des at a 2:1 ratio. The only high duality habitat areas on the Site (ether wetland areas, blues and ravines along Brown Creek and Pinch Gat Creek) will be included in the undeveloped buffer areas. In a letter dated September 1, 1998, we provided information to the Corps on the lack of practicable alternatives to placing £ill in the wetland areas (Attachment 17).. used on this information,. the Corps concluded .in the Public Notice that. "the proposed, project appears to..bethe least' environmentally damaging 'practicable alternative."

F`ish and WildfifcServlce (Servic:6) and the Departm�mf'of the Interior to the public notice dated October 22,1998, for a permit application submitted by ChambersDevelopment of Notth Carolina., IncorporaVA, to impact waters of the United States in conjunction with the construction of a new municipal solid waste landfall `t^of Wadesb6ro"in Anson County, north Carofl a. This report is based on a site visit and a review of the public notice and is submitted in accordancewith the provisions of the Fish and Wildlife Coordination Act, as amended (16 U:S.C. 661-667e), and the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act). We are concerned about the quantity of wetlands and strews impacted and the potential effects to water quality from the proposed landfill. The Brown Creek subbasin received a "fair" bioclassiftcation Barn the North Carolina Division of Water Quality. Nonpoint-source pollution is a current problem in the brown Creek sdbbasin. We are also increasingly concerned .about the loss and fragmentation of upland habitat due to projects such as this; we offer here some rneasures to minimize these adverse effects but expect we will seek mitigation for impacts to upland habitat for fixture projects. I at l Cola„ id-u. The proposed project is adjacent to, and upstream of; several excellent examples of natural community types that are dependent on natural hydrologic regimes and are not common in North Carolina. These natural communities are piedmont levee forest (vegetative assemblages on seasonally or intermittently flooded natural levees and point bar deposits on flood plaints), piedmont bottomland. forest (vegetative assemblages on hood plain ridges and terraces adjacent to riven char nels), piedmont swarup forest (vegetative assemblages on back -swamp deposits and sloughs), and flood plain pool (depressions in abandoned river channels on flood plaints holding water much or all of the year). Natural communities like these provide habitat for a variety of annuals, such as game species (white-tailed deer, raccoon, cottontail rabbit, gray squirrel); Neotropical migratory birds (Kentucky warbler, wainson's warbler, downy woodpecker, towhee, Carolina wmn, mockingbird, white -throated sparrow, common grackle, blue jay); and numerous butterflies, amphibians (frogs, salamanders), and fishes (sunfishes, darters, rosyside dace). unity to: Feee Dee Nafigngl Wildlife Refu �. The proposed landfill is close to the Fee Dee National Wildlife Refiige (Refuge). Situated on the bauks of the Fee Dee River in the southern portion. of the lbwer pie€irt Gnt, the Refuge"s 8,443. ace range from bottomland hardwood forest to land sine: diverse Idlife; habitat; also includes abandoned fields, naturally reforested areas, cultivated land, and over a dozen ponds and creeks The primary objectives of the Refuge: to provide wintering habitat for Canada geese and -ducks, provide sanebimy for wood ducks, protect and m& ce habitat for the endangered led -cockaded woodpecker, and provide interpretation and recreational opport mities for the public. The Refuge attracts thousands of waterfowl annually, including blue wing teal, mallards, ring neck ducks, Canada geese, and snow, geese, and provides important habitat for the American woodcock, snipe, and red -cockaded woodpecker. The endangered red -cockaded woodpecker is a ycar-round resident, and the bald eagle and peregrine falcon (both threatened) are transient visitors. Twenty-eight species of mammals can be found, including beaver, bobcat, fox, white-tailed deer, raccoon, opossum, squirrel, rabbit, and pine vole. The Refuge bird list contains over 170 species, including bobwhite quail, mourning dove, Canada geese, and prothonotary warblers. There are also over 56 reptiles and amphibians, including Fowler's toad, eastern musk turtle, six -line racertinner, and rough green snake. Based on the proximity of the proposed landfill to the Refuge, we are quite concer-r,ed about the indirect effects to the Refuge from the issuance of this permit. We are particularly concemedd about the potential impacts of this proposed landfill on migratory birds and mobile carnivores. Nonnative or gregarious flocking birds are often attracted to uncovered or windblown waste at landfill sites. Will flocking sea gulls be attracted to the landfill? We are also quite concerned 2 about the potential for carnivores to be attracted to the site. We believe that daily ever management and fencing may address some of these wildlife issues. Are detailed -operational plans available? What type of fencing will be installed at the proposed landfill? What will be the fence monitoring/repair schedule? These questions and issues need to be addressed in the environmental document developed for this permit. R=o mendations. We are providing thel following general recommendations:: for incorporation into the project plans to Mlinj=i e the impacts of this project on fish and wildlife: 1. All storm -water outlets should drain through a vegetated upland area prior to reaching any stream or wetland areas ; Sufficient retention designs llcallow f®r the slow discharge of stoma water, attenuafing the potential adverse effects of storm -water surges, thermal spikes, sediment; nutrient; and chemical discharges. We�iti ag_t�- Plans for the proposed wetland mitigation at the tributary to gown Creek should be submitted for our review immediately, because we have many doubts about its feasibility. What type of wetland will be emated? Will the wetlandxely on groundwater or over -bank flooding for hydrology? How will the: wetland tunction relative to the piedmont semipermanent impoundment downslope? Will the railroad grad: affect hydrology at the mitigation site? We recommend preservation of the remainder of wetlands on the tract thmugh a permanent, registered easement. treaaraMitigation. Since we have been disappointed with recent compensatory stream mitigation efforts for other projects, we request the opportunity to review all stream channel relocation/restoration designs and field delineations prior to construction and prior to the diversion of water. We believe a successful stream mitigation playa will need to first describe what the natural channel is relative to the principles of fluvial geomorphology as well as what functional relationships it will have relative to upstream and downstream aquatic communities. 3 'Since the watershed area of the proposed mitigation site is inadequate to support perennial stream. rchannels, we do not agree that the creationirestoration of stream channels here will be commensurate with the proposed impacts. We can assist in identification of more appropriate stream channel segments for restoration within. the Brown Creek watershed area. We agree that a 2e l ratio of mitigation to impacts is appropriate for the proposed strew impacts. We recommend the following elements be included in any strearn mitigation plan for this project: 1. Riparian vegetation should' include native goody species, such as alder (Alnus spp.) and black willow, as well as gl?undinaHa, sedges, grasses, and rushes. E--odc -vegetation should be screened from any plant material. Large wood species will provide thermal cover as well as deep bank -stabilize groot Y systems along any const mcted,br reconstrnctcd sty channel. I Stream chapel construction and vegetation eeablishrnent should. take place Prior to the diversion of water into the new channel- Sequential construction of segments and temporary pipe diversions can be utilized to ensure channel stability. We would like to have an Opportunity toinspect stream segments for stability prior to the water diversion. 3. Stream chapel design should mimic slope, rife a sla pool slope, valley. slope, pe> slpe,::mnde8 erne try, smuosrty, cross -sectional dimensions, entrenchment ratio, ,bed: a1 (pebble-munt), and b Ul: d harge of a nearby reference reach of a stable stream of the same classification' (Rosgen 1996). Bank -fail dimensions should be generated based on, ,those -of an appropriate reference reach and/or the latest discharge(charmel dimension relationship developed: for the piedmont (vie can suPp Y l a. .py of these. es if needed): . e would like to review the final of the stream channel restoration and relocations. 4. Monitoring should continue —tor at least 5 years following channel construction. ua.l reports should be submitted to the resource agencies. Resource agencies should be notified of problems with success or function of the stream mitigation within 30 days of detection. 5. An appropriate regional conservation Organization should hold title to the deed restrictions on the mitigation site. The title to the conservation easement should be conveyed along with an endowrnent for future monitoring, management, and any contingencies to ensure a perpetual net increase in stream channel function in the project area. Since North Carolina law currently requires the filing of conservation easements every 30 years, the endowment should make provisions for the required legal filing. 4 IN 6. The remaining tributaries to Pinch Cut Creek and Brown Creek within the property should be set aside in a permanent conservation easement. 7. We recommend enhancement of the. riparianbutler on the West side cif Brawn . Creek with bdtternland'hardw ocid`species: Plantings should extend at least 100 feet from the strearn. 8. The final mitigation plan should provide details relative to what measures will be taken to contrail watershed. conditions and prevent sediment pollution and increased water discharge that would potentially negate efforts at the stream mitigation site(s). °he latest draft "Guidelines for stream relocation and restoration in North Carolina," by the 'North Carolina Wildlife Resources Commission, is a ood D :ide to proper sLrea_*ra restoration d relocation work. 4L7 Based on a review of our records andour knowledge of the site, we concur with the ennination that there will be no effect to listed' species.

Anson County, North Carolina. These comments are prcvided :tr accordance with. provisions of the Fish and Wildlife Coordination Act, as amended (1-5 U.S.C. 651--667d) and Seczion 7 of t. a Endangered Species Act as amendad. ,.,0 6._ 3. S._.C. 1531µ- �.A3 ) Based on' the results` afthe endangered ,pec es surveys, we corker. that the proposed facility is not likely to adversely affect Federally -listed endangered cr threatened species. Therefore, the requirements of Section 7 of the Act have been satisfied. However, obligations under Section 7 of the Act roust be reconsidered if., (1) new, nf.ormation reveals impacts cf this identified action that may affect listz : spec,;.es or. czitidal Habitat in a manner not previously cans tiered; (2) this action is subsequently mcdified in a manner which was not considered in the document; or (3) a reefer species is listed or critical habitat determined that may, be affected liy the ...identified ...action. . The Service has interest in the. proposed landfill site due to it's proximity to the pee Dee Naticnal gildlife Refuge (Refuge) . In additon to the location of the propaved site, the Service is concerned with the water quality of the creeks bordering the site. Pinch Gut Creek flows into 6rowr creek,the main drainage for the County, and eventually floes directly through the Refuge. Water from Brown Creek is used to floed wildlife impoundments within. the Refuge. Because ct the previous alteration �,t toe proposed site b-v the pine plantation, and the measeires taken to avoid and greserVe buffer areas along Brown and Pinch Gait Creeks, the Service believes that wetlands are not likely t� be adversely immaczed physically by the facility. Efforts to have these aet.land buffers managed as permanent ccnservatiun easements is encouraged. 00: 47 T L6 = J.:)C 20cd 022,� ::Ntl Z ES2 Z ©L_EQL.L The service offers tie,, follow .ng tec -ini.Ca1 assistance cosnmeests. on issues noted during this review. Tne section in the site Plan Application regarding the typo, quantity and source of wastes indicates that the facility will be Lece.lvinq contaminated soils. We recommend that than type, level anti quantities of contaminated. soil that the facility is proposing to accept be included in the environmental documant and made availiable for public reviewand comment The Service strongly recommends that: contaminant monitoring. of the proposed facility include biota and sediments: in addition. to the currently proposed plans to monitor surface water, ground water, and leachate. Sediment and biota represent potential contaminant sinks through adsorption (sediments) and bioaccumulation (biota)m These media would be more representativp_ in assessingth.e long --terms impacts > of the facility than data provided only by groandwat<er and surface water quality monitoring. Species'the:service recommends for monitoring include mussels (e.g. E1112t.ic cod lanata;, turtles `m-g. snapping turtle chelvd�7 a sermentina) , and fist., including warmauth, bullheads; and suckers. `these biota and sediments should be.-ca'liected t the surface water man�,tcring stat.io.ns Pinch ... .Gut.. and Brown Creeks and, anal -_ed annua 'Iy. The first.. collections of these media shru„d ..occur rziLor. to .Iandf ilI development to establish a baseline.

M-LkeGant-t sure`visor directly on the baseliner. leachate collection pipe{s) will be installed in the drainage layer to collect and convey the leachate to the leachate sumps located along the deep end of the landfill. lzachate collected in the sumps will be pumped out by submersible pugs placed in the leachate sumps via the side slope risers. Pumped leachate will be transported to leacchate storage tanks via a farce -main. 1_.eachate pumped from the system will be temporarily stored in the leachate storage tank(s) before transported off -Site to the local POT W for. treatmentand disposal. The leachate storage . tarok will. be "surroundedby concrete -walled secondary containment to contain, and prevent release of the leachate should the tannic fail or leap. An active landfill gas control system is proposed to prevent on -site accumulation gases errerated in the landfill by decomposition of the waste. The landfill gas control system will also .pressure exerted on the barA'ier .soil layer and the membrane bra the cap and control odor. The system will consists' of gas extraction wells, collection headers and blower(s) to evacuate the landfill gases. A flare will be installed to butte gases collected - The proposed landfill design incoiporates stormwater and `sediment measures intended to prevent accelerated soil erosion and off -site sedimentalicr, The final landfill surface will include side slopes terraces at nominal 40 feet vertical intervals. The side slope terraces will intercept the storrnwater runoff and discharge it to pipe drawn spouts. The pipe down spouts will discharge into the perimeter ditch Storrnwater-collected in the perimeter ditches will be .diverted..to one of the three sedimentation basins surrounding the landfill footprint for detention and discharge to the streamrss in the site vicinity. The proposed perirter ditches and basins will be vegetated or rip -rapped to minimize potential for erosion. Outflow from. the basins will be controlled by riser - type outlets and discharged to a rip -rap apron to reduce flow yelocities and erosion potential. 1.2.4 Lear -hate Mana�er�nt 1.2.4.1 Leachate Collection S stern The landfill has been divided into sixteen landfill cells separated by limed soil ber[ns. The leachate generated in the cells will be collected by the leachate collection system and discharged to a. sump. Each cell will be provided with a leachate surnp located near the perimeter berme at the lower end of each cell. The proposed layout and details of the leachate collection system are shown on Drawings No. F-2 and F-4 of the facility plan set. The engineering basis of this design is given in Sections 2.1.3 and 2.2.1.1. 1-6 1.2.4.2 Leachate Collection Taraina e !Me The proposed leachate collection layer will consist of. a I2-inchthick granular layer with a miniar► m pe ility,of 0.1. crW= gr:.greater.. A.survey of the ,borrow sources in the area was performed to identify. potential sources and the availability of borrow materials nneting this criterion. A soil sample was obtained from one of the borrow sources (B.V. Hendrick Gravel and Sand, Lilesville,.. North Carolina) .and submitted for laboratory gnddation and perrrr-ability tests. "Test resents: indicate that: the pem=bility ef,t.h s material is expected to exceed the design requirermnt. The drainage layer will be placed directly on trip of the base liner (georriernbrane). The proposed landfall design provides a m soil subgrade post-settlernent ,slope of 2% along the drainage.;, sand layer to ensure: flow of leachate. to, the leac=e collection sumps at the lower ends ofthe:landfill.1botprint. The proposed design also includes.geosynthetic drainage corraposite (geonet) as an -alternate to the granular drainage. layer.... . 1.2.4.3 "l ,P" Model AgW3y,,s and Collection system S�mg L,eacirare flows were estimatedby rmdeling rain water balance. through the landfill using the HELP Model (Section 2.2. 1. 11). Conditions during the initial waste placer Ent operationsof a cell will generate maximum leachate due to accumulation of 100% of the precipitation within the separation berm (Le.,, no runoff allowed) and infiltration of learchate flow by the waste tWckness in place. A waste.thickness of five feet was utilized to model the _in ial . operating conditions in each cell. The initial operating condition am conservatively assumed to be the "Normal Operating Condition" forevaluating the proposed -design.. The in itrattion rnovernent (balance) across into, through and out of the landfill was analyzed easing EPA's Hydrologic Evaluation -of Landfill Peffommce (HELP) cocxtputer ...gro.graasi, Version 3....( aectio.n;.2..2..1:.LI).. iand.ciimatolo.gical data for Charlotte, North Carolina available in the, HELP database were utilized for dmr analyses. Analyses were performed for the following three conditions - Initial Condition (T of waste in -place); ® hate Condition (waste placed to 60 ft., no cap); and e Final Condition (waste to full Height and capped). IIELP Model analyses results are sununarized on 'Tables 1 and 2 of Section 2.2. Based on the HELP Model analyses, a peak daily leachate generation rate of 44 gpm is estimated in the largest cell (2A) under Norz ml Operating Condition. Eased on the HELP analyses results for these three conditions (bulleted above), peak daily and average monthly/daily leachate generation rates were calculated for different stages (phases) of the landfill development. 1-7 NCDE regulations (15A NCAC 13B.164(b)(2)(A)].:.and Sxxbtitle D require limiting the leachate head on the liner to one foot with an impinge. rat rate on.t:he drainage layer. equal to the peak monthly precipitation rate. To evaluate the performance of the leachate' collection system on top of the geomembrane, additional HELP analyses were performed with the precipitation aniount. set to the " peak rre ahly rate". The historic monthly precipitation>data (1938 to 1995) for the nearest location (Wadesboro, N.C.) was obtained from the U.S. Weather. Bureau, National Climate Data Center hornepage an the "World -Wide -Web'. This precipitation data was used to calcuiate ,men monthly. precipitation and the .standard deviation. The :value: two standard deviation above the me (97 5%© confidence level) was used as. the "Peak Monthly Precipitation lute' for the HELP analyses. A daily precipitation €ate calculated 'l'r€ m the peals nionthly,rate (Weak Monthly Precipitationitate130) and specified for 365 days in the HELP input to nnodel a steady-state precipitation condition. The results indicate that for the -proposed base slope, the damage layer peiunability and t.he: collector pipe spacing,. the peak daily, head on the liver will not exceed one foot as requited by the xIN .EHNR Subtatle: D regulations. . 1.2.4.4 Leachate Collection Piers The proposed 6-inch-diameter (RDPE) leachate collection pipes at the typical slope of one percent have an estimated flow capacity of about 350 gpm which is significantly greater than the peak daily leachate generation rates estimated by water balance method (FIE1LP analyses): The leachate collection .system pip design includes cleanout, risers along the. perimeter landfill berm to provide access for cleaning throughout the operating and post -closure ire period of the facility: Location. of the cleart:raxt:risers :are . showrs:on Drawing No- F;4 of the facility plan set, Section I.1;2. Details of clean out risers are shown on Drawing E-10 of the engineering drawings, Section 2.5. 1.2.4.5 Leachate Collection Sumps and Paxrsps The leachate collection pipes are designed to gravity discharge to leachate collection sumps located at the perimeter of each cell. Leachate collected in the sumps will be punted out via sideslope pump riser and conveyed via a leachate force main to 100,0W gallons (nominal capacity) leachate holding tanks. From the holding tanks, the leachate will be trucked off -site for disposal at the County wastewater treatn-&nt plant. In the future, Chambers may elect to pursue direct discharge to the municipal sewer (available along U.S. route 74). The sumps will be equipped with automated level and alarm sensor to automatically operate the landfill sump pumps and indicate pump failure to the operator. Proposed layout and details of the leachate sumps, sideslope riser, force main and, storage tanks are shown on Drawings No. E-11 and E-12, Section 2.5. 1-8 The icachate collection sumps have a base dirnension of about 15 feet by 15 feet and a: storage height ofthreeand a half feet with 3 horizontal to 1 vertical sidesippes. Tlie estimated: available "live" storage volurrz of each sump is approximtely 16,000 gallons. Each. sunup in an active cell will be equipped with a 50 gpan (30 gpm if geonet is utilized) nominal capacity submersible pump. For inactive (capped) cells, each suanp will be equipped with. a:. 15 gpin pump. The sunup and pump am designed to provide acceptable pun p. cycle of nes/starts per day. 1.2.4.6 leachate Ford Main _... ........ l eachate collected: in the collection sumps will: be pumped to a leachate storage tank via a force -amain. The force-nmian will consist of SDR-21, high density polyethylene. pipes. The force -amain pipes will be of 4-- or 6--inch-diameter. Calculations (Section 2.2), indicate that the proposed pumps will.have adequate by capacity, discharge floe leachate from landfall sumps to the leachate storage tanks via the force-nnain. 11.4.7 Le-achate Corntain-ment Eerraa The proposed design includes perimeter beams and cell separation benans to control and contain the leachate in. the: areas provided within:: the base liner. The sube-611` separation berms wiIprevent. mixing of ft leachate horn adjacent cells .and act as-storanwater separation berm prior to the develop =nt:or-construction of dieadjacent cells, Per NCDEHNR requirement [15A NCAC 13B.1624(b)(2)(A)), the top of [he perimeter and .the cell separation bermes are: designed to contain the voluan of leachate generated.by a.24-hour, 25-year storm: 1.2.4S L,eachate Storage and Disposal. The leachate will be stored in a 100,000 gallon, ahove-ground, belted steel tank(s) located on the southwest side of the faciiaty The storage tanks will be surrounded by 'a concrete -walled secondary contain=nt to contain leachate if the tank should leak- The calculated containment volunne within the concrete walls is designed to exceed the tank vokirne by more than the 10%® required by the NCDEHNR regulations [15A NCAC 13E.1680(c)(2)(A)j. The storage tanks will be equipped with a renting system and water level sensor alamas to indicate high liquid level to the operator and to shut down the pumps in the sumps if the tanks are full. Location, layout and details of the leachate storage tank are shown on Drawing No. E-12 of the playa set. 1-9 d LES ASS ITS, INC.

RESPONSE Within the property, the location of the solid waste boundary has been defined in an attempt to meet the location restrictions contained within the North Carolina Department of Environment and Natural Resources (TIC DENR) Solid Waste Regulations, The regulations state that new (1) Department of the Army, Wilmington Disuic% Corps of Engineers — Letter, Allen S. Davis to Brian Card, P.E., "Action I.D. No. 199900592, dated August 10, 1998, Mr. Allen S. Davis Department of the Array, Corps of Engineers September t, 1998 Page 2 municipal solid waste landfill (MSWLF) units must establish a minimurn;00-foot buffer between the MSWLF unit and all property lines and a minimum 500-foot buffer between the MSWLF unit and existing private residences and wells. In addition, the location of the solid waste boundary is further restricted by the existence of the CSX railway and related right-of-way along the southern boundary. Due to the.requirernents for. landfill siting and construction established by SIC DENR; it is increasingly difficult to site any new solid waste facility without encount�ring wetlands or jurisdictional waterways. In particular, North Carolina is highly dissected and has a line network of small intermittent tributaries, perennial streams and associated wetlands. In many cases of new landfall siting, wetland avoidance is not possible, since a parcel of land for potential landfill development must be sufficient in size, on the order of several hundred acres, to include the MS`YVLF unit and its required buffers: soil borrow areas, and ancillary facilities. A wetland delineation was conducted by Garrow & Associates in late 1991 and early 1992. The purpose of the delineation was to identify all existing wetlands so that any potential wedand> iripacts could be avoided.;._ The solid waste_ boundary w , designed to avoid the wetlands delineated at that time and the Pernir:to Construct, including this design, was subrnitred.for approval to the Solid;Waste Section of NC DEAR. however, some time following the design and lavout of the landfill and the submittal to NC DEAR, the Corps, in a site survey on February 24, 1998, delineated additional areas along intermittent drainage channels that were deemed to be jurisdictional. These subsequent findings by the Corps were within.the previously defined landfill footprint:: Complete avoidance of jurisdictional wetlands, as defined recently by the Corps of Engineers, has been evaluated. However, at this point, wetland avoidance by .relocation of the solid waste ........... boundary is not feasible. The intermittent drainage channels (wetlands) being affected are of marginal quality and the relocation of the solid waste boundary would impact higher quality and more diverse wetlands within the property boundary. This does not appear to be an alternative, as the permitting process for the currently designed facility is nearing its completion. COMMENT B It is necessary for you to have taken all appropriate and practical steps to reduce wedand losses. Please show all that you have done, especially regarding development and modification of playas and proposed construction techniques, to reduce impacts. RESPONSE Chambers has attempted to minimize wetland losses by developing the upland portions of the property.

COMMENT The 1 OA, ;requires that appropriate and practical mitigation will be required for all unavoidable adverse impacts remaining a ter all appropriate and practical minimizndon has been employed. You have furnished a draft plan to mitigate for the projected, unavoidable loss of waters and wetlands. You have been asked to submit the draft mitigation plan to the (North Carolina Division of Water Quality for review and input as to what mitigation will be required to satisfy state requirements. You are requested to advise this office of all such state requirements. RESPONSE The proposed Anson County Solid Waste management Facility will result in the unavoidable fill of approximately 1.6 acres of wetlands. As you are aware, Chambers proposes to offset the loss of the 1.6 acres of wetlands by constructing an additional 3.3 acres of wetlands, at least twice as much wetland habitat as that which will be lost as a result of landfill construction, in another area of the property.
