These systems maybe permitted by_a Non -discharge Recycle System_ Permit from the Aquifer Protection Section (APS). OR may instead be permitted under NCG020000 to eliminate an additional permit_ Recvcle systems that do not meet those criteria are considered discharainq systems and are subject to the NCG020000 discharte permit. **To obtain 7Q10 flows, permittees must contact the DWQ Stormwater Permitting Unit. If DWQ does not have a flow estimate fora specific stream, permittees will be asked to obtain one. Permittees should contact J. Curtis Weaver at the USGS: 919-571-4043, for more information on obtaining a 7Q10 flow. USGS will not determine a 7Q10 flow for tidally influenced water bodies. _Reviewed by: DWQ RO Surface Water: �1�,2�Regional Offic Date:?�f �-- RO Aquifer Protection Section: Regional Office: Date: SPU DWQ Central Office Reviewer (if applicable): 1�J � '....0 c�-c.QSZ. 4-��r,�,. av�- 1�Yla►�e.S�-� �-�-�. �?�rz Rev September 2010 January 20, 2012 Ms. Linda Willis Division of Water Quality Wilmington Regional Office 127 Cardinal Drive Extension Wilmington, N.C. 28405 "-/ Dear Ms. Willis: This letter is to serve as a narrative of mining operations and dewatering procedures for the CLD Pit (Robert Preston Willis) in Carteret County that you visited with us back on September 2, 2011. The type of discharge that will be present on the site will be Leine dewatering. Reference is made to the site plan that illustrates the points of discharge from the mine. Robert Preston Willis proposes to dewater mining operations through the following sequence of events. 1. Erosion Control items will be installed prior to any mining activities on the site. Sediment Basins, Diversion Ditches, and Level Spreaders will be installed per plan design before mining activities begin in any area of site. 2. Excavation will begin in pit area 2 (indicated on map) in the southern most point and continuing north. When mining activities extend below the water table, water will begin being pumped into basin 1, where it will have time to settle and once it reaches the height of the level spreader it will flow over the 50 undisturbed buffer ., back into the wetlands rehydrating theirs. 3. Excavation will continue in pit area 2 leaving a 10 foot damn between the first 1 0 pond and the second pond area, still in pit area 2. Water will now be pumped into the first excavated area then it will be pumped to the basin area 1 and out through the level spreader. 4. Once the third pond area is done we will go back to the first 10 foot damn and knock it out creating a larger area of settling for the water to be pumped from pond area 3 into this larger area then out through the level spreader. ^' 5. This process will continue throughout the entire site. b. There are two extra basins proposed in the plans for dewatering if wetland i hydration is inadequate and needs to be dewatered in multiple areas to distribute equally. These are indicated on the plans by basin 3 and basin 4. r+,} •yr \/J• j�^} �CL� i�lt�^ q�� 1°� rJ��,�i'`Sal1'�,,• t�,..

The type of discharge that will be present on this site will be mine dewatering. Reference is made in the site plan that illustrates the primary point of discharge and also secondary points of discharge from the mine. Robert Preston Willis proposes to dewater mining operations through the following sequence of events. 1. Erosion control items will be installed prior to any mining activities on the site. Sediment basins, diversion ditches, road ditches, silt fencing, and levels spreaders will be properly installed per plan design before mining activities begin in any area of site. These items will also be properly monitored and maintained. 2. Excavation will begin in Pit area 1 (indicated on map)in the north eastern most point of limit and continuing south widening out both east and west as limits allow. 3. When mining activities extend below the static ground water elevation (37 inches below ground elevation) the water will be pumped into settling basin 1 (136 feet by 45 feet being 6 foot in depth, with a overspill dam (lined with fabric and class b stone) 2 feet below top of berm) allowing elements to settle. 4. Dewatering of pit will be done with a NorthStar Semi -Trash Pump. It has 3 inch ports with a rating of 15,850 gallons per hour (126,800 per 8 hour day). It is powered by a Honda GX160 engine. Based on this information the pump will not pump more than the discharge limit of 150,000 per day advised by Linda Willis. ' Cam 5. Once the water is pumped into Settling Basin 1 and reaches the point of the spill dam, it will run across the class b stone into a ditch in which it will then travel approximately 2500 feet until it reaches the level spreader. Along ditch, every 200 feet water will travel into a smaller basin (12' x 12') and run through a rock check dam at each one. Once coming out of the level spreader at the end of this ditch and traveling over another area of class b stone and fabric it would run over the ground to where it eventually discharges into a mosquito control ditch. The closest conveyance via the mosquito ditch to the mainstream of Williston Creek would put the discharge where the creek is 70 feet across. 6. Basins 2-5 will only be installed and used to the point that the discharge infiltrates completely into the wetlands so that the wetlands will remain hydrated. Ensuring that no discrete discharge will occur from these wetlands to the ditch on the south side of the site because that ditch discharges to Howland Creek.
