Hams, Mining Program Secretary Land Quality Section FROM: Sheri L. Bryant, Piedmont Region Coordinator Habitat Conservation Program DATE: 28 February 2006 SUBJECT: Mining Permit Modification for Hanson Brick, Gulf Mine No. 3—Permit No. 19-11, Chatham County, North Carolina Biologists with the North Carolina Wildlife Resources Commission have reviewed the subject permit request and we are familiar with the habitat values of the area Our comments are provided in accordance with provisions of the Mining Act of 1971(as amended, 1982XG.S. 74-76 through 74-68 15 NCAC 5). The applicant is requesting a modification of their permit for mining clay and shale The total permitted acreage is 318.5 acres. The proposed modification involves 105.9 acres within the previously permitted boundary. The applicant indicates the operation will involve discharging stormwater through the sediment control structures; a 200 fool buffer will be maintained between land disturbing activities and natural watercourses or wetlands; the site will be grassed and seeded; and one stream crossing is required to access a portion of the mine site. An unnamed tributary to Dap River Flows through the site. Deep River is in the Cape Fear River basin. Thereare records for the federal and stme endangered Cape Fear shiner (Notropis meldstocholas); the federal species of concern and state significantly rare Carolina redhorse (Moxastoma sp.); and the stale special concern notched rainbow (Fillosa constricla) in Dap River. We are pleased a 200-foot buffer will be maintained along the unnamed tributary to Deep River. This will reduce impacts to aquatic and terrestrial wildlife resources, water quality, and aquatic habitat both within and downstream of the project area. We have the following recommendations to further reduce impacts to aquatic and terrestrial wildlife resources. Water discharges from the project site should be proportional to the size of the receiving stream, and all discharges should comply with NPDES permit requirements. In particular, turbidity of the discharge should be maintained at or below the permit requirement. High water discharge rates and turbidity can negatively impact aquatic and fisheries resources within and downstream of the Mailing Address: Division of Inland Fisheries • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919)707-0220 • Fax: (919)707-0028 2-d 929L-6bb-9EC 3ueRag --I-S Clot:20 90 L2 qaj E E� Page 2 28 February 2006 Gulf Mine No. 3 Permit No. 19-11 project area. Excessive silt and sediment loads can have numerous detrimental effects on aquatic resources including destruction of spawning habitat, suffocation of eggs, and clogging of gills of aquatic species. 2. We encourage the applicant to consider using seed mixtures that are beneficial to wildlife in their reclamation plan, such as native, warm season grasses. An exact seeding mixture would need to take into account soil types, moisture, pH, and degree of slope of areas to be stabilized. Additionally, for relatively shallow sediment basin reclamation, we recommend these areas be reclaimed as wetlands where practicable. We refer the applicant to George Stradcr, District Wildlife Biologist at (919) 471-1743 for additional information and ideas on reclamation for wildlife. Use bridges for all permanent roadway crossings of streams and associated wetlands to eliminate the need to fill and culvert, where practicable. If culverts must be used, the culvert should be designed to allow passage of aquatic organisms. Generally, this means that the culvert or pipe invert is buried at least one foot below the natural streambed. If multiple cells are required, the second and/or third cells should be placed so that their bottoms are at stream bankfull stage. This will allow sufficient water depth in the culvert or pipe during normal flows to accommodate movements of aquatic organisms. If culverts are long and sufficient slope exists, baffle systems are recommended to trap gravel and provide resting areas for fish and other aquatic organisms. if multiple pipes or cells are used, at least one pipe or box should be designed to remain dry during normal flows to allow for wildlife passage. In addition, culverts or pipes should be situated so that no channel realignment or widening is required. Widening of the stream channel at the inlet or outlet of structures usually causes a decrease in water velocity causing sediment deposition that will require future maintenance. Finally, riprap should not be placed on the streambed. Thank you for the opportunity to review and comment on this permit modification. if you need additional information, please contact our office at (336) 449-7625. cc: Roy Turner, Hanson Brick cc: Mark Bowers, FWS Sarah McRae, NHP Ryan Heise, WRC Brian McRae, WRC E'd S29L-13ib-9EE queRJE -I's d81:20 90 L2 q9J t NCDENR North Carolina Department of Environment and Natural Resources I,A'Michael F.

Webb, P.G., C.W.C. �� Ground Water Management Section Division of Water Resources SUBJECT: Comments on the Mining Permit Application for: Hanson Brick Gulf Mine No. 3 Chatham County FEB 10 2006 i Please find attached it copy of the mining permit application for the referenced project. Based on the information contained in this permit application, it is unlikely that this operation will have an unduly adverse impact on the area's ground water resources. The amount of ground water pumped from the pit is relatively small. Additionally, the low permeability of the clay materials being mined at this site will likely keep off -site impacts of this pumping to a minimum.

Box 361 pleasant GardcrI 27313 FFF8 $C GIVLD RE: New Gulf Mine Modification 03 70d6Chatham County, NCPenni[No. 19-11 i1t::;:.ITY SCCTi2M1� Dear Mr. Garvey: Following is a general discussion of the mining project and erosion control evaluation for the above -referenced New Gulf Mine. The conclusions of this evaluation are reflected on the prepared mine map. GENERAL PROJECT INFORMATION The New Gulf Mine (Permit No. 19-I1) contains an approximately 318.5-acre tract of land in Chatham County, North Carolina off Murchison Road (SR,1925) Currently, 87.4 acres of land is allowed to be disturbed. An additional 105.9 acres of land is to be disturbed within the next 10-years. Mining will continue as proposed at the existing permitted acres. However, Basin D has been modified so that the outlet structure can be placed at one or both locations. The new outlet location is labeled D2. Subsequent Basins F, G, H, 1, 1 and associated berms will be added to collect stormwater runoff from the new mine areas. One stream crossing is required to access these basins. During construction of the stream crossing, temporary silt fence and sediment traps will be installed. The basins consist of diversion berms with brickbat outlets. The basins can contain the runoff from the 10-year rain event, and the outlets can pass the 25-year rain event. The stream crossing will consist of two (2) 48" diameter concrete culverts. The proposed new mine areas are screened by the existing topography or by 50ft wooded buffers. A 200ft wooded buffer will be provided for the stream. Upon completion of mining activities, the disturbed areas will be sloped for positive drainage and vegetated per the vegetation plan. Berms, stockpiles, and sediment basins will be removed with positive drainage provided. Roadways indicated on the mine maps will remain in place. 0 0 The stream crossing is considered temporary -and will be removed upon completion of mining activities. EROSION CONTROL DISCUSSION The SCS TR-55 Method was used to calculate the 10-year and 25-year rain events for Basins F, G, H, 1, f and D2 and the stream crossing. Based on the USDA Soil Survey, the predominant soil types at the site include Carbonton ("C" Hydraulic Group), Mayodan (`B" Hydraulic Group) and Udorthents ("B" Hydraulic Group). However, for design evaluation, a "D" Hydraulic Group was used to calculate for the Basins. For the Culvert watershed area, Carbonton ("C" Hydraulic Group) soils are predominant and a "C" Hydraulic Group was used. The watersheds for Basins F through S will be increased by the excavation activities. The greatest disturbance was used to evaluate maximum flow rates and runoff volumes. The Basins were designed to temporarily contain the runoff from the 10-year rain event. The outlet for the basins will be constructed of brickbat. The crest width is important to minimize or prevent scour of the brickbat during the 25-year rain event. Therefore, the water level over the crest of the brick section was limited to 3 inches. Stability analyzes for scour of the brick (incipient motion of brick particles) was determined for the 4:1 (H:V) downslope section of the brick. These analyses (assuming about 3 inches of water overtopping the crest) indicate that a suitable factor of safety against brick scour is at least 3.9. Steady-state seepage slope stability analysis was also conducted for the downslope 4:1 (}I:V) brickbat section. Steady-state seepage slope stability analysis indicated a suitable factor of safety against failure of 3.7. The Rational Design method was used to size the temporary sediment traps needed during the stream crossing construction. A "C" value of 0.5 for disturbed soil and 0.15 for woods and grassland was used for the calculations of the 10-year and 25-year storm event. Fs • P' J CLOSURE We appreciate serving Hanson Brick on the New Gulf Mine. Please contact us if you have any questions. Sincerely, T. �atrick Shillin t n President Attachment : Erosion Control Calculations EIS E ATTACHMENT: Erosion Control Calculations Us E 0 EROSION CONTROL New Gulf Mine The SCS TR-55 Method was used to calculate the 10-year and 25-year rain events for Basins F, G, H, I, J and D2 and for temporary erosion control for the proposed newly - installed culvert(see Attachment B). Based on the USDA Sol] Survey, the predominant soil types at the site include Carbonton ("C" Hydraulic Group), Mayodan ("B" Hydraulic Group) and Udorthents ("B" Hydraulic Group). However, for design evaluation, a "D" Hydraulic Group was used to calculate for the Basins. For the Culvert watershed area, Carbonton ("C" Hydraulic Group) soils are predominant and a "C" Hydraulic Group was used. The watersheds for Basins F through J will be increased by the excavation activities. Tile greatest disturbance was used to evaluate maximum flow rates and runoff volumes.
