HomeMy WebLinkAbout2---Item-20-Combined-Narrative-and-AResponse to Item #20, ADI Letter dated July 23, 2020 20. Please provide revised plan drawings which include the following: Coordinates in decimal degrees to 4 decimal places at locations along permit boundary as needed to accurately define the permit boundary. Over thirty Lat/Long points have been added to WSC Site Plans along the existing and proposed permit boundary, all of which are visible on pages 2 and 3 of 11. b. Detailed plans including appurtenances and equipment for pumping water from the proposed pit to the existing pit. Equipment, pipe specifications, and plans for crossing Crabtree Creek along the side of the proposed bridge have been added to WSC Site Plan page 6 of 11. Pump curve data and engineering calculations are also attached to this response demonstrating that the proposed pipe is more than adequate to safely move water from the new pit to the existing pit. A portable 8" pump will be utilized in the developing pit to remove accumulated stormwater and groundwater. Up to 100' of 8" HDPE pipe will attach to the pump for ease of movement as the pump is relocated during pit sinking activity. However, to reduce friction and pipe pressure, 12" steel or equivalent (14" HDPE) pipe will be used to pump water up to the 280' MSL elevation at the top of the new pit. Attached pump calculations show that pipe pressures will be between 14-21 PSI at the top of the pit (depending on depth and distance to the pump) - well within the design specification for the proposed pipe. From the 280' elevation, the pipe will continue inside additional 18" welded steel pipe (or sealed troughs where pipe elbows are needed), which will be supported by welded brackets on the side of the bridge. The 18" steel pipe will be open at both ends such that, in the extremely unlikely event of a leak or rupture of the internal pipe, any water that might escape would gravity drain either back into the new pit or into the old pit. C. A detailed construction sequence addressing practices that will prevent sediment loss to Crabtree Creek during retaining wall and bridge construction. A detailed construction sequence, titled "Bridge Construction Schedule" has been added to the PLD Erosion Control Plan Cover sheet. Directly under the sequence is an explanation addressing the prevention of sediment loss to Crabtree Creek. Written summary of retaining wall design calculations demonstrating that the design meets or exceeds the factors of safety reported on Sheet 6 of the S&ME plan set. A complete "MSE Retaining Wall Calculation Package" is attached to this response. Loaded 100-ton haul trucks were utilized in the retaining wall calculations as noted in the stamped and sealed cover letter dated September 29, 2020 (65-ton haul units are proposed), in order to provide an additional factor of safety. Consistent lines for riparian buffer delineation with labels for zone 1 and zone 2. Wake Stone has a 100' self-imposed buffer from the centerline of Crabtree Creek. Regulatory riparian buffers are measured from top of bank, not stream centerline. The 100' buffers were based on existing buffers as described in the current mining permit. They were not intended to be riparian buffers, but rather "property" buffers measured from the property line (which includes the centerline of Crabtree Creek). However, with the addition of leased RDU Airport property across Crabtree Creek, Wake Stone acknowledges that "property" buffers are not necessary and have therefore been removed from the maps for the sake of clarity. Riparian buffers are clearly labeled on all Erosion Control Plan and Wake Stone Site Plan maps, including zone 1 and zone 2 of Neuse Buffers where applicable. The 250' undisturbed buffer from the center line of Crabtree Creek adjacent to Umstead State Park is the only "property" buffer that will continue to be measured from the centerline of the creek. This buffer has been in place since the beginning of Triangle Quarry. The entire construction entrance should be shown within the permit boundary. The limits of disturbance line has been revised to encompass the construction entrances. However, the permit boundary along Old Reedy Creek Rd is proposed to be the edge of the DOT Right of Way for this public road, rather than the property line which is closer to the centerline of the road. Please note that the northern construction entrance is an existing road onto the property that would only require minor improvements as illustrated on the plans. The relocation of the construction entrance will be done as soon as is practicable and will require a NCDOT Street and Driveway Access Permit. In some basins, the skimmer outlet is in the footprint of the emergency spillway. The emergency spillway should be constructed in undisturbed soil and the skimmer outlet located outside of the spillway footprint. The basins have been revised on all E&SC and Site Plans to shift the emergency spillways into undisturbed soil, and the skimmer outside of the spillway footprint. The only exception is the location of the emergency spillway for temporary Basin #4. Because this basin receives runoff from diversions at either end of the basin, it is not possible to locate the emergency spillway in undisturbed ground without risking potential bypass of the basin from one or the other diversion channels. Instead, the entire spillway weir will be lined with an impermeable fabric and lined with Class B rip rap as detailed on SITE 12 of the Erosion Control Plan despite the fact that, with the 25-year storm design, the additional riser outlet and minimum 1' of freeboard, it is unlikely that the emergency spillway will be activated in the time that the basin is in place. Stable conveyances from channels or culverts into basins, in order to prevent erosion and internal system sediment loading into the basin mouth. Slope drains or rip rap protection is provided on the revised Erosion Control Plan at every location where stormwater enters the basins. Adequate outlet protection devices at the end of slope drains and culverts on the plan sheet. Rip rap energy dissipaters are provided on the revised Erosion Control Plan and labeled at the outlet of each slope drain, each culvert, and each skimmer outlet. Overall erosion and sediment control (E&SC) plan for both pits that identify all stormwater discharge outlets (SDOs). The overall plan (SITE 2 of the Erosion Control Plan) has been revised to include the entire project on one sheet and to add the SDO labels for each stormwater discharge outfall. Page 3 of the WSC Site Plans also includes the entire project with all SDOs labeled. k. Planting plan (riparian where required) for screening and stabilization adjacent to proposed headwall. No riparian disturbance is proposed beyond the construction of the end bents and the extension of proposed wing walls. No screening is necessary, since the proposed bridge will not be visible from any adjoining properties. Silt bag detail and maintenance requirements. Silt bag detail and maintenance requirements have be added to SITE 10 of the revised Erosion Control Plan, although Wake Stone is more likely to pump water from basins into either the expansion pit or the existing pit if necessary for basin maintenance. M. Dimensions of construction entrances on plan sheets. The construction entrance labels have been revised on the Erosion Control Plan to include the dimensions and specifications. Clarification that construction entrance would be installed before any timbering begins. Timbering is only allowed to the extent necessary to install perimeter E&SC measures. The existing construction entrance would be improved prior to any logging activity. The construction entrance would be relocated to the south as soon as is practicable. However, perimeter E&SC measures would need to be constructed before access roads and logging paths to the new entrance could be constructed. Wake Stone would prefer to utilize the improved existing access road for timber removal only to the extent necessary to install E&SC measures, and then remove remaining timber through the relocated new construction entrance or possibly across the proposed bridge, if completed. o. Check dams as needed in diversion ditches to reduce energy of channelized water. Check dams have been added in all diversions per the revised Erosion Control Plan P. Plans showing diversion ditches routed so that discharge passes through at least 2 baffles prior to entering skimmer cell. Lower diversion ditch enters basins 5 & 6 in the skimmer cell. All diversions have been revised to ensure that they enter the basins such that water must travel through at least two baffles prior to discharge. Clarification that the location of the diversion ditch between basins 5 & 6 is correct. The location is correct. The ditch was designed to divert water away from basins 5 & 6 to prevent the need for large basins that would require more significant land disturbance. These two basins are expected to be removed within the first year of stripping activities. Plans indicating that disturbed areas between the primary perimeter ESC measure and diversion ditch will be seeded and mulched immediately. This note has been added to each set of "Erosion Control Notes" on the revised Erosion Control Plan. Reconciliation of the access road it is shown in the undisturbed buffer (sheet 4). Clearing limits and limits of disturbance line has been revised to encompass the construction entrances. t. A legend with symbols/icons to identify all proposed erosion and sedimentation control measures. Measures must be to scale. Use the symbols to identify the proposed location of the structures on the plan. Terminology must be consistent throughout the plan. A legend has been added to the plan sheets of the revised Erosion Control Plan for proposed measures. Identification of slope drain sizes on the plan sheets. Slope drain sizes have been illustrated on the revised Erosion Control Plan. Identification of pipe and culvert sizes on the plan sheets. Culvert sizes have been illustrated on the revised Erosion Control Plan. W. Plans labeled with all structures (i.e. diversions, rip rap outlets, FES structures) to correspond with the associated design calculation. The diversions have been labeled numerically on the Erosion Control Plan sheets and correspond with the design calculations. A chart has also been added on sheet SITE 11 to specify diversion ditch dimensions and liner requirements. Another chart has also been added on SITE 11 to specify energy dissipater requirements at each slope drain and culvert. Each plan sheet contains notes under "Erosion Control Notes" referring to the charts on the detail sheets. X. The symbol used for silt fence must be distinct and not hidden beneath the line type used to delineate the limits of disturbance. The Erosion Control Plan has been revised to make the lines clearer, including the use of color for silt fence, riparian buffers, and property lines. Y. Areas identified where liners/matting will be installed using a symbol provided in the legend or identifying hatch pattern. A hatch pattern has been added to diversion ditches where rip rap liner is required. The hatches are labeled on the plan and included in the legend provided on each sheet. An overall plan sheet for each phase of the erosion and sedimentation control. The overall map is to be at a scale so that the entire site fits on one sheet. The overall plan (SITE 2 of the revised Erosion Control Plan), has been revised to include the entire project on once sheet. aa. A supplemented seeding and planting plan that considers native vegetation in and around riparian areas. As noted in "k." above, no riparian disturbance is proposed beyond the construction of the end bents and the extension of proposed wing walls. bb. Remove weeping love grass from the seeding plan. Weeping love grass has been removed from the seeding plan. CC. Provide additional erosion and sedimentation control measures as required to protect the stream, all public, and private property from damage. All proposed erosion and sedimentation control measures and best management practices are based on accepted engineering standards. The significant due diligence prior to submittal of a mining permit application demonstrates Wake Stone's commitment to the protection of streams and adjoining property. The permit modification application submitted in April was the result of years of research, stakeholder engagement, planning, geological and hydrogeological investigations, engineering and design by Wake Stone, as well as by highly respected consultants. Providing additional buffers above and beyond regulatory requirements, carefully thought-out site development plans, including visual berms, flood protection, and avoidance of stream and wetland impacts, Wake Stone does not believe any additional erosion and sedimentation control measures are required beyond those proposed in the initial application and refined or clarified in this response package. dd. Immediate stabilization with seed and mat on basin side slopes upon construction. This note has been added to "Erosion Control Notes" on the revised Erosion Control Plan sheets. ee. A minimum of 5 feet between the toe of the slope and the installation of the silt fence. Silt fence has been adjusted where necessary to ensure 5' of separation from the toe of all fill slopes. ff. Adequate space for the installation, maintenance and removal of perimeter silt fence. Specific maintenance requirements for all proposed sediment and erosion control structures included on the plan. Wake Stone is confident that adequate space had been provided for the installation, maintenance, and removal of silt fence. On some of the steeper slopes, this may require manual labor in lieu of mechanized equipment, but Wake Stone will not disturb any areas not illustrated on the accompanying Erosion Control or Site Plans without authorization from the Division of Energy, Mineral, and Land Resources. Specific maintenance requirements for all proposed sediment and erosion control structures are illustrated on sheets SITE 10, 11, and 12 of the revised Erosion Control Plan. gg. A plan detail and construction specifications for the silt fence and silt fence outlet that complies with the skirt trench requirements per the Erosion and Sediment Control Planning and Design Manual. The skirt is to be trenched in, at a minimum, 8 inches vertically and 4 inches horizontally. The silt fence detail on SITE 10 of the revised Erosion Control Plan has been corrected to meet the new Planning and Design Manual requirements. hh. A structure/device for dewatering the temporary basins prior to removal and/or conversion to a permanent structure. Provide a plan detail, construction specifications, and maintenance requirements for this device. Include the use of this device in the construction sequence. Silt bag details and maintenance requirements have been added to SITE 12 of the revised Erosion Control Plan. However, as noted in letter "I." above, Wake Stone is more likely to pump water from basins into either the expansion pit or the existing pit, if necessary for basin maintenance. A plan detail, construction specifications, and maintenance requirements for the sediment skimmer basin with riser. Include a stone pad for the skimmer to rest upon and a rope attached to the skimmer for maintenance in the plan detail. Include the basin surface area dimensions, depth, side slopes, dam height, embankment width, length of emergency spillway, barrel diameter and barrel length, skimmer size, skimmer orifice size, and dewatering time on the plan sheets. A detail and chart containing all of the requested data above has been added to sheet SITE 12 of the revised Erosion Control Plan. jj. Anti -flotation calculations for the riser structure. Include the dimensions of the riser structure, barrel pipe, and anti -flotation block on the plan sheets. The calculations have been revised to include the anti -floatation device. The detail on sheet SITE 12 of the revised Erosion Control Plan includes the dimensions of the anti - floatation block. kk. Description of how water will be discharged into the basin in a manner to prevent erosion. Provide a stable conveyance from diversions into basins (i.e. rip rap lined channel, slope drain, tarp, etc.). Use diversions to channel runoff into the basins and prevent sheet flow. As indicated in section "h." above, slope drains or rip rap protection is provided at every location where stormwater enters the basins. Construction specifications for the skimmer basin are to include the excavation, embankment construction, spillway construction, and skimmer basin installation. Specify on the plan detail that an impermeable liner is to be installed on the spillway. The emergency spillway is to be installed in undisturbed ground (not over the skimmer pipe). Include a stone pad for the skimmer to rest upon and rope attached to the skimmer for maintenance in the plan detail. Include the basin surface area dimensions, depth, side slopes, dam height, embankment width, length of emergency spillway, skimmer size, skimmer orifice size, and dewatering time on the plan sheets. A detail and chart containing all of the requested data above has been added to sheet SITE 12 of the revised Erosion Control Plan. mm. Design calculations for peak discharge rate for the 25-year storm. Provide all supporting data for the computation methods used (rainfall data for required storm events, time of concentration/storm duration, and runoff coefficients used). Several basins are noted to be designed using the 10-year storm. It is not clear which storm is used to calculate diversions and rip rap structures. A detail and chart containing all of the requested data above has been added to sheet SITE 12 of the revised Erosion Control Plan. nn. Provide design calculations, a plan detail, construction specifications, and maintenance requirements for the outlet stabilization structures. Construction specifications for the outlet stabilization structure are to include the width of the apron at the pipe outlet and at the end of the apron, the length of the apron, the stone size, and depth of stone. A detail and chart containing all of the requested data above has been added to sheet SITE 11 of the revised Erosion Control Plan. oo. Provide liners/matting to aid the stabilization of planned channels and temporary diversions when the runoff velocity will exceed 2 ft/sec on bare earth during the 2-year rainfall event that produces the peak runoff. The product(s) selected must have a permissible shear stress that exceeds the shear stress of the design runoff event. If liners/matting are to be installed, provide a plan detail, construction specifications, and maintenance requirements. Include the installation of liners in the construction sequence. A detail and chart containing all of the requested data above has been added to sheet SITE 11 of the revised Erosion Control Plan. The construction sequences on the cover sheet have been revised to note that liners must be installed. The calculations have been revised to include the calculations for all diversions, including shear strength analysis. Additional Considerations: On the original Erosion Control Plan and Wake Stone Site Plans, a fifty -foot undisturbed buffer was illustrated along the northern proposed permit boundary, with a security fence as proposed by RDU Airport Authority. RDUAA proposed only ten feet of undisturbed buffer with a thirty-foot clearing for the security fence, essentially clearing our proposed buffer. Therefore, after negotiations with RDUAA, Wake Stone has agreed to provide the security fence for the Odd Fellows tract. Wake Stone will still be required to use the style of fence proposed by RDUAA as illustrated "Typical RDU Security Fence" on page 10 of 11 of WSC Site Plans, but instead of a ten -foot undisturbed buffer and thirty-foot clearing, we are proposing a 25-foot undisturbed buffer, a 10-foot clearing outside the fence, and 15-foot clearing inside the fence. However, the clearing for the fence will only be removal of vegetation; stumps will either remain or be ground in place, and mulch used for ground cover. No clearing will take place in zone 1 of the Neuse Buffer and only minimal clearing of vegetation in zone 2 in order to continue the fence across the buffers around Foxcroft Lake and to extend to Crabtree Creek at the western and eastern property boundaries.

(S&ME) has completed the authorized MSE retaining wall designs for the Wake Stone Quarry project. Our services were performed in accordance with our Proposal for Retaining Wall along Perimeter Road and Proposed Bridge dated January 31, 2020 and the Agreement for Services (AS-071), entered on January 21, 2020 between Wake Stone Corporation (Wake Stone) and S&ME. Design drawings were submitted on March 28, 2020. This package includes the calculations associated with the previously submitted drawings. The mechanically stabilized earth retaining walls are designed using the following products and materials: Block 2' x 3' x 6' concrete blocks Reinforcement Mirafi 5XT and 10XT uniaxial geogrid Reinforced Backfill Sands and Gravels (SP, SM, SW) Traffic Surcharge 450 psf Because of the variability of the physical properties of the concrete block, the retaining walls were designed without considering the weight of the block as resistance. S&ME used the MSEW software and the FHWA-NHI- 10-024 method model the internal and external stability of the wall and determine geogrid length and spacing. The traffic surcharge used in design was estimated based on a loaded 100-ton haul truck and the load distribution described in with AASHTO Standard Specification for Highway Bridges. The surcharge was applied at the top of the wall where the perimeter road will be. Global stability was analyzed using SLIDE 8 by RocScience using limit equilibrium analysis to estimate the factor of safety.
