Harris Mining Program Secretary Land Quality Section FROM: Gabriela Garrison Eastern Piedmont Coordinator Habitat Conservation DATE: June 3, 2021 SUBJECT: Mining Permit Application for Tara Group of Lumberton, Inc., Tara Group Mine, Bladen County, North Carolina. Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the subject permit application. Comments are provided in accordance with provisions of the Mining Act of 1971 (as amended, 1982)(G.S. 74-46 through 74-68 15 NCAC 5). Tara Group of Lumberton, Inc. is requesting a new permit to mine sand. The proposed site is 42.8 acres; 32.3 acres of this area will be disturbed. This was a pre-existing permit (#09-16) that expired. The applicant has indicated that erosion and sediment control measures will be installed around the site, to include buffer zones, a perimeter silt fence with outlets, temporary diversions, earthen berms and three temporary basins. The operation will discharge fresh or wastewater from the site; a temporary sediment basin and two temporary skimmer basins with temporary diversions will be used to capture stormwater runoff. Sediment will then be allowed to settle to the bottom of the basin The reclamation plan includes re -vegetating disturbed areas in accordance with permanent seeding specifications. The excavated site will be reclaimed as a pond. The proposed project is located south of Tarheel Road, west of its intersection with Red Oak Farm Road, southwest of Tar Heel. Aerial maps and images indicate Big Swamp flows west of the project area; a tributary to Big Swamp bisects the project site. If the permit is issued, the NCWRC offers the following recommendations to minimize impacts to aquatic and terrestrial wildlife resources: 1. A minimum 100-foot undisturbed native, forested buffer along perennial streams and a minimum 50-foot undisturbed native, forested buffer along intermittent streams and wetlands should be maintained between any mining, construction or land -disturbing activities. Maintaining undisturbed, forested buffers along these areas will reduce impacts to aquatic and terrestrial wildlife resources, water quality and aquatic habitat both within and downstream of the site. In addition, these buffers will provide a travel corridor for wildlife species. Grassed buffers, particularly fescue, do not provide the necessary and highly valuable functions that forested buffers provide. Sediment and erosion control structures should be located outside of the buffers.

Any wetlands and streams within the site boundaries should be identified through on -site surveys prior to any land -disturbing activities. If wetlands and/or streams will be impacted by mining activities, the proj ect should be coordinated with the U. S . Army Corps of Engineers and the N. C. Division of Water Resources. 3. Water discharges should be proportional to the size of the receiving stream, and all discharges should comply with National Pollutant Discharge Elimination System permit requirements. In particular, turbidity of the discharge should be maintained at or below the permit requirement. High water discharge rates and turbidity can negatively impact aquatic resources within and downstream of the project area. Excessive silt and sediment loads can have numerous detrimental effects on aquatic resources including destruction of spawning habitat, suffocation of eggs and clogging of gills of aquatic species. 4. Consider using seed mixtures that are beneficial to wildlife (e.g., native warm season grasses) in the reclamation plan — see attached Table. The NCWRC strongly recommends against the use of Sericea lespedeza (Lespedeza euneata) as a stabilizing groundcover. This is an egregious and invasive, non-native species that is very hard to eradicate. An exact seeding mixture should account for soil types, moisture, pH and degree of slope of areas to be stabilized. Relatively shallow sediment basins can be reclaimed as wetlands where practicable. Free technical assistance from NCWRC biologists is available for ideas on establishing vegetation or incorporating other measures that are beneficial for wildlife. 5. Sediment and erosion control measures should be installed prior to any land -clearing, construction or disturbance. The use of biodegradable and wildlife -friendly sediment and erosion control devices is strongly recommended. Silt fencing, fiber rolls and/or other products should have loose -weave netting that is made of natural fiber materials with movable joints between the vertical and horizontal twines. Silt fencing and similar products that have been reinforced with plastic or metal mesh should be avoided as they impede the movement of terrestrial wildlife species.
