Peele Construction Mr. Charles Ray Peele, President 462 Holly Shelter Road Jacksonville, NC 28540 Project Name: LCID Site @ Four Points Mine No. Project No.: ON-2017 Location: NCSR 1744 - Onslow County River Basin: White Oak Submitted by: Parker and Associates Date Received: July 31, 2001 New Submittal Dear Mr. Peele: This office has reviewed the subject sedimentation and erosion control plan. We find the plan to be acceptable and hereby issue this Letter of Approval. The enclosed Certificate of Approval must be posted at the job site. This plan approval shall expire three (3) years following the date of approval, if no land -disturbing activity has been undertaken, as is required by Title 15A NCAC 4B.0029. Please be advised that Title 15A, of the North Carolina Administrative Code, 4B.0018(a) requires that a copy of the approved plan be on file at the job site. Also, you should consider this letter to give the Notice required by GS 113A-61(a) approved plan. The last page(s) which lists approval comments should be copied and attached to the sedimentation and erosion control plan that is maintained on site. North Carolina's Sedimentation Pollution Control Program is performance oriented, requiring protection of the natural resources and adjoining properties. If, following the commencement of this project, it is determined that the erosion and sedimentation control plan is inadequate to meet the requirements of the Sedimentation Pollution Control Act of 1973 (North Carolina General Statute 113A- 51 thru 66), this office may require revisions to the plan and its implementation to insure compliance with the Act. Acceptance and approval of this plan is conditioned upon your compliance with federal and state water quality laws, regulations, and rules. In particular, if wetlands are effected by this land disturbing activity, the provisions of the Clean Water Act as mandated by the Environmental Protection Agency must be adhered to. In addition, local city or county ordinances or rules may also apply to this land - disturbing activity. This approval does not supersede any other permit or approval. 127 Cardinal Drive Extension, Wilmington, N.C. 28405-3845 • Telephone 910-395-3900 • Fax 910-350-2004 An Equal Opportunity Affirmative Action Employer Mr. Charles Ray Peele August 15, 2001 Page Two Please note that this approval is based in part on the accuracy of the information provided in the Financial .Responsibility Form which you provided . You are requested to file an amended form if there is any change in the information included on the form. In addition, it would be helpful if you notify this office of the proposed starting date for this project. We look forward to working with you on this project.

The developer is responsible for the control of sediment on -site. If the approved erosion measures prove insufficient, the developer must take those additional steps necessary to stop erosion from leaving this site. Each sediment storage device must be inspected after each storm event. Maintenance and/or clean out is necessary anytime the device is at 50% capacity. 3. Any and all existing ditches on this project site are assumed to be left undisturbed by the proposed development unless otherwise noted. The removal of vegetation within any existing ditch or channel is prohibited unless the ditch or channel is to be regraded with side slopes of 2 horizontal to .1 vertical or less steep. Bank slopes may be mowed, but stripping of vegetation is considered new earth work and is subject to the same erosion control requirements as new ditches. rl. The developer is responsible for obtaining any and all permits and approvals necessary for the development of this project prior to the commencement of this land disturbing activity. This could include agencies such as the Division of Water Quality's stormwater regulations, their enforcement requirements within Section 401 of the Clean Water Act, the U.S. Army Corps of Engineers' jurisdiction of Section 404 of the Clean Water Act, the Division of Coastal Management's CAMA requirements, the Division of Solid Waste Management's landfill regulations, the Environmental Protection Agency and/or The U. S. Army Corps of Engineers jurisdiction of the Clean Water Act, local County or Municipalities' ordinances, or others that may be required. This approval cannot supersede any other permit or approval, however, in the case of a Cease and Desist Order from the Corp of Engineers, that Order would only apply to wetland areas. All highland would still have to be in compliance with the N.C. Sedimentation Pollution Control Act. 5. if any area on site falls within the jurisdiction of Section 401 or 404 of the Clean Water Act, the developer is responsible for compliance with the requirements of the Division of Water Quality, the Corps of Engineers and the Environmental Protection Agency (EPA) respectively. Any erosion control measures that fail within jurisdictional wetland area must be approved by the aforementioned agencies prior to installation or our Section must be notified of a relocation of the measures in question to the transition point between the wetlands and the highlands to assure that the migration of sediment will not occur. If that relocation presents a problems or contradicts any requirements of DWQ, the Corps or the EPA, it is the responsibility of the developer to inform the Land Quality Section regional office so that an adequate contingency plan can be made to assure sufficient erosion control remains on site. Failure to do so will be considered a violation of this approval. 6. Any borrow material brought onto this site must be from a legally operated mine or other approved source. A single use borrow site or an area to waste material is only permissible if it is operated under total control of the Financially Responsible person or firm who is developing this site, is located on or adjacent to this site, and has been incorporated as part of this plan. 7. This permit allows for a land disturbance, as called for on the application plan, not to exceed 1.9 acres. Exceeding that acreage will be a violation of this permit and would require a revised plan and additional application fee. Any addition in impervious surface, over that already noted on the approved plan, would also require a revised plan to verify the appropriateness of the erosion control measures and stormwater retention measures. Page 2 of 2 8. Because the sediment retention ponds are shown on the plan as the primary sedimentation and erosion control devices an this project, it is necessary that the ponds and their collection system be -installed before any other grading takes place on site. If that proves impractical, a revised plan must be submitted and approved that addresses erosion and sediment control needs during the interim period until the ponds are fully functioning. 9. The silt trap/diversion ditch detail is confusing as a drawing and could result in improper construction. The rip-rap/stone outlet needs to be the depth as the trap's pit to assure eventual drainage between storm events otherwise retention time maybe insufficient when water is standing from earlier storms. The diversion ditch should be graded to smoothly transition into the bottom of the trap; otherwise, a sudden grade change will cause erosion in the ditch. 10. A graveled construction entrance must be located at each point of access and egress available to construction vehicles during the grading and construction phases of this project. Access and egress from the project site at a point without a graveled entrance will be considered a violation of this -approval. Routine maintenance of the entrances is critical. 11. The proposed brush barrier is not an appropriate erosion and sediment control measures and its inclusion in this plan should not be viewed as such. Its presence could be a hindrance to the maintenance of the appropriate erosion and sedimentation control measures and should be omitted if it limits access to other locations on the site. Future applications that include brush barrier construction will be disapproved. 12. The North Carolina Sedimentation Pollution Control Act mandates a shortened time frame in which to reestablish vegetative groundcover. Slopes (including cuts, fills, and ditch banks) left exposed will, within 15 working days or 30 calendar days (whichever is the shorter) after completion of any phase of grading, be planted or otherwise provided with groundcover sufficient to permanently restrain erosion.

This inspection was performed to determine compliance with the North Carolina Sedimentation Pollution Control Act of 1973. The inspection revealed a land -disturbing activity of approximately 1.4 acres being conducted. It is our understanding that you and/or your firm are responsible for this land -disturbing activity. The purpose of this letter is to inform you that this activity was found to be in violation of the Act, NCGS 1 13A-50 to 66, and Title 15A, North Carolina Administrative Code, Chapter 4. If you feel that you are not responsible for the following violations, please notify this office immediately. The violations that were found are: Failure to file an erosion and sedimentation control plan with this office at least 30 days prior to beginning a land -disturbing activity on a tract comprising more than one acre, when more than one acre is to be uncovered, failure to secure this office' s prior approval of the plan for any land -disturbing prior to beginning the land -disturbing activity NCGS 113A-57(4) and 15A NCAC 46.0007(c). An approved erosion and sedimentation control plan does not exist for the cleared LCID area of 1.4 acres. The mine permit boundaries of Four Points Menerals Mine #1, #67-55 have been exceeded. 127 Cardinal Drive Extension, Wilmington, N.C. 26405-3845 • Telephone 910.395.3900 • Fax 910350.2004 An Equal Opportunity Affirmative Action Employer Mr. CR Peele May 18, 2001 Page Three Please be advised that any new land -disturbing activity associated with this project must not begin until the area presently disturbed is brought into compliance with the Act. When corrective actions are complete, you should notify this office so the work can be inspected. You should not assume that the property is in compliance with the Act until we have notified you. After installation, all erosion control measures must be maintained in proper working order until development is complete and the site is completely stabilized. We solicit your cooperation, and would like to avoid taking further enforcement action. At the same time, it is your responsibility to understand and comply with the requirements of the Act. Copies of the relevant statute and administrative rules may be examined at this office or will be sent to you upon request.
