Farrell Shingleton., we are submitting a response to your comments emailed 6/18/2021, Please find your comments listed below with our response provided in bold. 1. Please clarify the estimated withdrawal rate in gallons per day for dewatering at this site. • See pumping plan—460,000 GPD when dewatering occurs. It won't be a continuous operation. 2. Question 12 of the application states that fuel tanks, solvents, or other chemical reagents will be stored on site.Please describe these materials,how they will be stored, and the method of containment in case of a spill. Please also indicate the storage location on the mine maps. • Off-Road Diesel Tank for farm and mine equipment is labeled on the maps. Tanks are contained in secondary storage devices. 3. Please clarify whether a well is located near the existing house shown on the mine map. • No there are no wells here.The house is just for farm display and not in use for storage or living. 4. Question 5(a) states that there will be no stockpile areas on site,while the mine map clearly indicates a stockpile and wastepile area. Please clarify whether material will be stockpiled,and if so,describe the reclamation of the area. • Yes that was in error; stockpiles and wastepiles are identified on the mine maps and accounted for in the affected acreage table. 5. Please clarify how dewatering will be accomplished within permit boundaries. • Dewatering will not be onsite as the application states, but offsite. An NPDES permit is issued,but we are verifying with Stormwater currently to determine the correct permit number,status,etc. 1 22 CINEMA D F I V E, W I L M I N B T C N , NO 2 B 4 D 3 P H : ( 9 1 ❑ ) 7 9 1 - 6 7 0 7 F A X : ( 9 1 D ) 7 9 1 - 6 7 6 D PARAMOUN E N G 1 N E IS F2 I N C.

We have located the corners near this permit by iron pins and have labeled with metes and bounds and coordinates here for this excavation area. Thank you for your attention to this matter. If you have any questions regarding any of this information or require additional material,please feel free to call. Thank you for your time and effort.

Farnell Shingleton 12919US Hwy 17 Hampstead, NC 28443 Prepared by: PARAMOUNTE ENGINEERING, INC. 122 Cinema Drive Wilmington, NC 28403 (910) 791-6707 1 of 2 Pumping Plan Narrative T. Farrell Shingleton is expanding the mine excavation areas of an existing sand mine permit. The mine is located at the end of Saps Rd at 904 Saps Rd. It has been in operaton for at least 10-years. This sand mine dewatering operations and monitoring plan is prepared to satisfy the requirements of Section E listed in the NPDES General Permit NCG020000. The proposed plan for this pit is to pump groundwater through a settling basin that discharges in a non-erosive manner to the adjacent buffers further away from the existing wetland 50- ft buffer. The wetland hydrology will be recharged during the dewatering rather than re- directing groundwater away from the wetland source. The property is in the Trumpeter Creek Watershed (C; Sw). During the intermittent dewatering activities, the estimated withdrawal rate in gallons per day will be 480,000 GPD based on a 1,000 GPM Pump running 8 hrs at a time. There are no residences within 500 ft of the property so no private wells will be affected. OPERATIONS SEQUENCE 1. Ensure all stormwater runoff flows into excavation pit. 2. Install piezometers in the wetlands as described below. 3. Prior to full dewatering, inspect blind swales and vegetation stabilization. a. Pump shall operate to a maximum of 480,000 GPD. b. After dewatering is complete, follow Mining and Reclamation Plans. MONITORING PLAN (a) Piezometers Installation Two piezometers (monitoring wells) approx. 3-4 feet in depth will be installed with data loggers adjacent to the mine boundary just outside the limits of disturbance within the wetland area. Current conditions must be logged and recorded prior to dewatering to determine baseline conditions. (b) Weekly Data Collection Each piezometers data logger will record water levels every week the dewatering operations are active. Data will be downloaded and documented. Rainfall will be with the use of on-site rain gauges. (c) Qualitative Site Evaluation Site evaluations will include a qualitative description of site conditions and photographs in order to document physical changes and monitoring. This evaluation will encompass an area within a 100 foot radius around the piezometers. Within this area, the land surface will be observed to identify evidence of soil instability, erosion, sloughing, subsidence, collapse and/or absence of hydration. The standard US Army Corp of Engineers Wetland Delineation Manual, latest edition, will be used to record soils, vegetation, and hydrology during this evaluation.
