The site has not been inspected for stormwater since the permit was issued. Due to lack of business - the mine was not operating for the entire 2013 year. We discussed the stormwater permit requirements with Josh Hughes at the site. They have a copy of their permit and site map. The map shows 5 outfalls for the quarry. The map needs to be updated to show 2 outfalls instead of 5. They do not have a stormwater pollution prevention plan. We told Josh he could get with his consultant to have one made or he could do the plan himself. We also told him to read the sampling requirements and to start qualitative/analytical monitoring. They are maintaining measures on site and the site looks good otherwise. Permit and Outfalls # Is a copy of the Permit and the Certificate of Coverage available at the site? # Were all outfalls observed during the inspection? # If the facility has representative outfall status, is it properly documented by the Division? # Has the facility evaluated all illicit (non stormwater) discharges? Comment: There are 5 outfalls listed on the map. There should only be 2 outfalls listed for the site. Site map needs to be updated to show less outfalls.

Wastewater discharges to Saltwater ORW will not be approved under the NCG02 General Permit. 17) If your facility has wastewater discharges and they are to HWQ, PNA waters (Primary Nursery Areas) waters, what is the flow rate? (See htty//www.ncdmf.net/maps/FNA maps/index.html, for map) 18) Discharge Points: Number of discharge points (ditches, pipes, channels, etc. that convey discharges from the property): Onsite: Stormwater: Mine dewatering: Process Wastewater Overflow: Offsite: Stormwater.5 Mine dewatering: Process Wastewater Overflow: Discharge points should be clearly marked on the submitted site plan. Please provide short narrative description of discharges: All stormwater discharging offsite if from sediment traps which are approved by DLR in the mining permit All 4 discharges are from sediment traps and are shown on the attached map. The traps are designed using the latest trap and basin design based on flow in cubic feet per second -rather than storage. a) Is your mine dewatering and discharging?

WHEN TWO SECTIONS OF FILTER CLOTH ADJOIN EACH OTHER THEY SHALL BE OVERLAPPED BY SIX INCHES AND FOLDED. 4. MAINTENANCE SHAH BE PERFORMED ,NS NOTED IN THE EROSION CONTROL PLAN. COLLECTED MATERIAL SHALL BE REMOVED WHEN 'BULGES" DEVELOP IN THE SILT FENCE. SILT FENCE DETAIL. NOT TO SCALE--- 1. Silt fence slail be constructed before upslope land disturbance begins. 2. All silt fence shall be placed as close to the contour as possible so that water vill not concentrate at low points in the fence and so that small swales or depressions which may carry small concentrated flows to the silt fence are dissipated along its length. 3. To prevent hater ponded by the silt fence from flowing around the ends, each tnd shall be constructed upslope so that the ends are at a higher elevation. 4. Where possble, silt fence shall be placed on the flattest area available. 5. Where possble, vegetation shall be preserved for 5 ft. (or as much as possible) upslope from the silt fence. If vegetation is removed, it shall be reestablidned within 7 days from the installation of the silt fence. 6. The height -3f the silt fence sham be a minimum of 16 in. above the nrigino ground surface. 7. The silt fence shall be placed in a trench out a minimum of 6 in. deep. The trench shall be cut with o trencher, cable laying machine, or other suitable device which will ensure an adequately uniform trench depth. 8. The silt feriae shall be placed with the stakes on the downslope side of the geotextie and so that 8 in. of cloth are below the ground surface. Excess mots"ial shall lay on the bottom of the 6-in.-deep trench. The trench shall be backfilled and compacted. 9. Seams betveen section of silt fence shall be overlapped with the end stakes of each section wrapped together before driving into the ground. 10. Mointenonee---Silt fence shill allow runoff to pass only as diffuse flow through the geotextie. If runoff overtops the silt fence, flows under or around the ends, or in any oher way becomes a concentrated flow, one of the following shall be performed, as appropride: 1) The layott of the silt fence shall be changed, 2) Accumulated sediment shall be removed, or 3) Other prlctiees shall be installed. Criteria for Sit Fence Materials 1. Fence Posts --The length shall be a minimum of 32 in. long. Wood posts will be 2-by-2in. hardwood o sound quality. The maximum spacing between posts sholl be 1 0 ft. 2.
