The Division has determined that your application is incomplete and cannot be processed. The application is on-hold until all of the following information is received: 1. If the U.S. Army Corps of Engineers requests a response to any comments received as a result of the Public Notice, please provide the Division with a copy of your response to the USACE. [15A NCAC 02H .0502(c)] 2. Please provide a copy of the most current DEMLR approved mine map with the proposed pit expansion areas and haul roads located on the map. [15A NCAC 02H .0506(b)(1) and .0502(a)(9)] 3. Please clarify whether the “pit” limits shown throughout the application materials depicts just the limits of the pits or the limits of the outer most proposed disturbed area necessary to mine within the pit area, such as disturbances for associated activities such as access roads, berms, sediment/erosion control measures, safety features, etc. [15A NCAC 02H .0506(b)(1) and .0502(a)(9)] 4. Please provide a site plan that shows the entirety of the proposed haul roads for the Bender Pit. The Division is unable to evaluate the project for avoidance and minimization without a complete understanding of the entirety of the proposed haul roads, including how the various pieces connect and where they terminate/begin within the pit and connect to other roads within the facility. [15A NCAC 02H .0502(a)(9)] 5. Please provide detailed plans for the stream relocation around the North Pit. The plans must include plan and profile details, accurate dimensions (including proposed side slopes and North Carolina Department of Environmental Quality Division of Water Resources 512 North Salisbury Street 1611 Mail Service Center Raleigh, North Carolina 27699-1611 919.707.9000 Martin Marietta DWR# 20220241 Request for Additional Information Page 2 of 3 floodplain access), any proposed buffers, proposed bed and bank materials and construction sequence/details. Please provide specific information regarding tie in locations with the existing stream. [15A NCAC 02H .0506(b)] 6. Please provide detailed plans and profiles for the proposed haul roads, as well as detailed construction sequences for each site. Please ensure that the plans clearly document that the proposed culverts will be installed to ensure equilibrium between the unimpacted portions of the wetlands and provide aquatic life passage. The plans should also include a detailed construction sequence demonstrating that the construction will be conducted “in the dry” and showing limits of all erosion control measures necessary to protect the adjacent wetlands. Please also clarify if any additional vegetation clearing will be needed adjacent to the proposed road for construction access. [15A NCAC 02H .0506(b)] 7. Please provide additional detailed information regarding the need for the second haul road, the “Overburden Road,” which is proposed to cross a large wetland complex between the existing mine facility and the proposed Bender Pit. While the Division recognizes that this road has been located in the narrowest portion of the wetland system, the direct impacts are still substantial and indirect impacts do not appear to have been considered. It is stated that “having a direct path” would reduce each trip, please provide maps with alternative road locations that were considered and the associated distances for each alternative to further justify this statement. Please provide further explanation of “necessary for operation efficiency and safety under the circumstances” and “substantial savings”. [15A NCAC 02H .0506(b)] 8. The Division needs to understand the projected volume of traffic that will use the Overburden Road in order to further evaluate Avoidance and Minimization. How many estimated trips will trucks and/or other machinery take per day over the proposed Overburden Road during: 1.) initial site development and 2.) mining operations. [15A NCAC 02H .0506(b)] 9. Please explain why a narrower road with traffic controls (e.g. the use of a flagger or remote light to control traffic) are not a practical alternative to the proposed designed with two travel lanes. [15A NCAC 02H .0506(b)] 10. Please explain how the roadway runoff will be captured/treated. Will any stormwater from the roads discharge into or adjacent to any wetlands or streams. [15A NCAC 02H .0506(b)] 11. Please provide an analysis of expected indirect impacts to the section of stream between the road and the portion to be rerouted around the North Pit. This section of channel will be further removed from downstream waters and be located between two impacted sections of channel which has the potential to further degrade the functions within the channel. [15A NCAC 02H .0506(b)] 12. Please provide a mitigation plan which will meet the requirements of 15A NCAC 2H .0506(c). Please note Item (c)(7) indicating that no more than 25% of the mitigation requirements may be satisfied through preservation. [15A NCAC 02H .0506(c)] 13. Please provide information to include a map showing any residential wells within 500 feet of the new pit boundaries. [15A NCAC 02H .0506(b)(3)] North Carolina Department of Environmental Quality Division of Water Resources 512 North Salisbury Street 1611 Mail Service Center Raleigh, North Carolina 27699-1611 919.707.9000 Martin Marietta DWR# 20220241 Request for Additional Information Page 3 of 3 14. The Division is concerned that indirect hydrologic impacts will occur in adjacent wetlands as a result of mining activities. Please provide a detailed hydrologic analysis/modeling of mining activities, including pit dewatering, on the adjacent wetlands. [15A NCAC 02H .0506(b)(3)] Pursuant to Title 15A NCAC 02H .0502(e), the applicant shall furnish all of the above requested information for the proper consideration of the application.
