This plan has been prepared by Parker & Associates, Inc. 1. SITE PLAN A. See the attached Exhibit 1— Color Portion of Kellum USGS map, and Exhibit 2 — Portion of Onslow County D.O.T. Map, and Mine Site Plan. B. The Pete Morton Mine is a proposed sand mining operation only. Sand shall be excavated and loaded directly into trucks and hauled off site to other locations. Loading shall be performed with an excavator. Other than normal daily maintenance, all equipment service shall be performed off site. No fuels or lubricants shall be stored near or in the mining area. Excavated material is normally wet so dust should not be a problem in mine. The haul road shall be monitored and periodically dampened utilizing a water truck when necessary to control any dust created from hauling operations. There shall be no waste generated from this operation, therefore, no disposal plan is needed. The possible pollutants to be concerned with are small amounts of fuel or hydraulic oil created by a ruptured hose or pipe on trucks or equipment. This should not be a normal occurrence but in the unlikely event that it does happen there always shall be someone on site to minimize and contain the spill before it reaches any water source. Any contaminated soils shall be removed and disposed of at a facility certified to treat soils. C. See the attached Mine Site Plan by Parker & Associates, Inc. D. There have been no significant spills or leaks at this location, therefore, no corrective actions have been needed. E. The discharge pipe for the dewatering pump shall be inspected daily when pumping. The discharge line is located in close proximity to power source for pump and 306 New Bridge Street I P.O. Box 976 1 Jacksonville, NC 28541-0976 1 (910) 455-2414 Firm License Number F-0108 I www.parkerjacksonville.com immediately after starting, pump discharge shall be evaluated to determine if any turbid non-stormwater discharge is present. Pumping shall be performed only as needed and never immediately after or during a rain event. Water shall be drawn from just below the surface (6"-12") of the water to pump the clearest water. Visual checks for clarity shall be performed each time the pump is operated. Any foam, discoloration or unusual odor shall result in immediate shut down of pump and discharge. Samples shall be collected and analyzed by a certified laboratory as required in the NPDES General Permit — NCG020000 and results shall be kept on site. Results shall also be forwarded to NC DEMLR annually as required by the General Permit. At any time sampling results exceed acceptable levels, discharging shall cease until conditions become more favorable and samples shall be taken monthly for a period of one year or as outlined in the General Permit. After such time, if levels have been consistently lower than acceptable levels, samples shall be drawn on a quarterly basis at minimum or as deemed necessary. Daily records shall be maintained on site recording times and amounts of pumping as well as recorded rainfall. 2. EROSION AND SEDIMENTATION CONTROL The site shall install and maintain all erosion control measures shown on the approved mine site plan. There shall be no gravity discharge of stormwater to the adjacent wetlands or creek; therefore, there are no special erosion and sedimentation control measures. The dewatering discharge shall pump into a rip rap lined basin, then flow through the sediment basin prior to flowing into the wetlands, then flow through couple hundred feet of wetlands prior to reaching the creek. The facility shall be operated and maintained in compliance with the mining permit issued by the Division of Energy, Mineral and Land Resources. 3. STORMWATER MANAGEMENT PLAN A. All excavation and land disturbance shall be confined to the mine area with only one controlled discharge source (dewatering pump). Natural grade in the area prohibits stormwater run-on as all areas sheet flow to wetlands away from mining area. No discharge of stormwater (pumping) shall occur until all solids have settled and water is clear. B. An inspection of mine slopes, entrance/exit, and stormwater protection devices (BMP's) shall be conducted weekly or within 24 hours of any storm event by the mine operator or other competent person. No discharge shall take place during or immediately after a storm event. A rain gauge shall be kept on site and monitored and all rainfall recorded. A record of inspections, deficiencies and corrections shall be recorded and kept on site. C. There shall be no bulk storage of any kind on this site. SPPP - 2 4. WETLANDS MONITORING The adjacent wetlands shall be monitored annually by a Soil Scientist to determine if the mine dewatering is having a detrimental effect on the wetlands.
