Please find attached a "Pumping O&M Plan" for the site. We strongly feel that the proposed modification poses no risk to any wells or wetlands. Please note that pumping and dewatering is allowed in the current permit and has been ongoing since the beginning of the operation many years ago, and there has been no negative impact whatsoever. This modification request is not to change or increase the pumping or dewatering, but only to allow discharge into the Roanoke River in times of flooding or excessing groundwater. There are no neighboring wells within nearly 3 miles of the site. The wetland identified on the site is located over 1,000 feet from the mine and is separated by a large lake (previously mined area). It is virtually impossible for the current dewatering to impact the wetlands at that distance and separated by the large lake. The lake serves to recharge the groundwater and surface water. To assure there is no impact, the O&M Plan requires the operator to continue to discharge into the lake as needed to maintain a high water level. Application was made for the NPDES General Stormwater Permit for Mining (NCG020)at the same time as the Mining Permit Modification Application. A copy of the application form is attached. Please let me know if you need any additional information.

Sincerely, Adam Parr Assistant State Mining Engineer cc: Mr. Samir Dumpor,PE Pumping Operation and Monitoring Plan Bent River Mine Certificate of Coverage NCG020*** Commercial Ready Mix Products Inc. Weeping Mary Road Bertie County, NC April 9, 2021 This PUMPING OPERATION AND MONITORING PLAN was prepared in accordance with the requirements specified in the National Pollutant Discharge Elimination System (NPDES) General Permit for Mining (NCG020), and specifically as applied in the Certificate of Coverage for this location: Bent River Mine Certificate of Coverage NCG020*** Commercial Ready Mix Products Inc. Weeping Mary Road Bertie County, NC Lat: 36.0955 Long: -77.2573 April 9, 2021 This plan is designed to satisfy the requirements of Part III, Section E of the NPDES General Permit NCG0200. Background: The NPDES General Stormwater Permit for Mining (NCG0200) addresses impacts of mine dewatering wastewater pumping and discharge on surrounding areas, including potential impacts to wetlands. The NPDES Permit requires that the mine have a site specific plan for, 1) groundwater monitoring strategies to demonstrate the effect of pumping and establish any pumping regime necessary to reduce potential impacts to surrounding areas, and 2) detailed plans to maintain surrounding hydrology and respective monitoring to demonstrate compliance. In order to develop these plans, certain site-specific parameters must be understood. First, any wetlands that may be potentially impacted must be identified in relation to the dewatering activity. Second, an evaluation of potential impacts of groundwater levels must be conducted. This should include an examination of soil types, permeability, and various zones of groundwater within the zone of influence. Third, based on the groundwater data, an assessment of potential impacts to the wetlands by mine dewatering should be estimated. Finally, based on the potential impact, a plan should be developed to limit as well as monitor the potential impacts to the wetlands. The Operation and Monitoring (O&M) Plan is developed prior to any discharge of mine dewatering wastewater. Site description: The Bent River Mine is a sand mine located in western Bertie County NC, on Weeping Mary Road. The property consists of 230 acres located about 4 miles west of NC Highway 11. The northern boundary of the property is the Roanoke River The site is mostly cleared field, with some wooded areas. The sand being mined is an alluvial deposit associated with the Roanoke River. The areas to be mined are all "upland" areas with the site being designed to maintain a minimum 50-foot undisturbed buffer between any land disturbance and any wetlands. The natural groundwater levels within the mining area are over 8 feet from the surface. The sand deposit being mined is an alluvial deposit consisting of a coarsening-downward sequence of sediments, ranging from a silty sand to a coarse sand and gravel. Wetland description: The wetlands found on the property are confined to the wooded areas of the property and are more than 1,000 feet from the mining area. There is a large lake between the current mining area and the wetland area, which serves to additional provide recharge of shallow water table.. The wetland area is associated with a drainage feature that flows into the Roanoke River. Hydrophytic vegetation is prevalent, and hydric soil and wetland hydrology are present, according to the USACE criteria. Depth to water table was within 6 inches from the surface at the time of the delineation. The wetland areas are shown on the mine map. Pumping and mine dewatering: This mine has been in operation for many years and has pumped and dewatered the mining areas as allowed in the current permit. The current permit modification requests that the water be allowed to discharge into the Roanoke River. Currently, water that is pumped from the mining area is held within the site to use in the closed loop recycle wash system and for dust suppression. At times when the water table gets exceptionally high, or during times of flooding, the water needs to be discharged from the site. Impact of dewatering on adjacent wetlands: It is important to note that mine pumping and dewatering has been permitted and ongoing at this site for many years with no impact to any wetlands. The high permeability of the soils limits the influence of the dewatering to a very close proximity of the pit. The water table of the site fluctuates several feet and is directly linked to the level of the water in the Roanoke River. Further, it should be noted that a large lake exists between the wetland area and the mining area. It is impossible for any mine dewatering to have any impact on the wetlands because the lake acts as a large recharge reservoir, providing more than sufficient hydration to the wetlands. Finally, it should be noted that the mining area is greater than 1,000 feet from any wetlands, providing a more than sufficient buffer. Therefore, the mine dewatering will have no impact on adjacent wetlands. Monitoring: Based on the presence of a large lake between the wetlands and the mining area. the great distance between the mining area and the wetlands, and several years of dewatering with no impact, it is practically impossible that any potential dewatering at this mine will have any impact on the adjacent wetlands. In order to confirm that there are no impact to the wetlands, a monitoring plan should be established as a precaution. 1. Mine dewatering wastewater discharges should be quantitatively and qualitatively monitored according to requirements of the NPDES permit. See the"Monitoring Requirements" in the Stormwater Pollution Prevention Plan. 2. The lake that lies between the mining area and the wetlands should be monitored to assure that the level does not significantly drop. If it does drop more than a few feet, the discharge water from the mining area should be re-directed into the lake to maintain high levels. 3. The Discharge Point should be examined weekly to make sure that it is functioning as designed. 4. A written record shall be kept of pumping times and rates. A record of rainfall shall also be kept in the Stormwater Pollution Prevention Plan.
