Ken Elliott Elliott Consulting 7/19/2023 -- - -- - ---------- --- -- ---- ------- --------- ------- -- Addendum-1 Page 6-Mine Permit Modification Application—Haskett Mine, Permit#72-21 C. Protection of Natural Resources Haskett Mine is an existing permitted 9.55-acre excavation in a 16.58-acre permit area owned by Whitehurst Sand, Inc. Excavation activities began in 2009 and have currently ceased, having excavated 6.4 acres. Owner now proposes to fill in the 6.4-acre excavated pond with clean fill sand and soil brought onto the site from outside the permit area. Sequence of events to do so are as follows: 1. Sequence of Events for Development and Operation: a. Operator will obtain all required mining permits from NCDEQ. b. Operator will maintain one gravel construction entrance at intersection of mine access road and SR 1129 Woodville Road. c. Operator will maintain existing foliage visual screen along perimeter of the affected area. d. Operator will begin filling existing 6.4-acre excavated pond (400'x 700')with clean fill soil until surface height reaches that of surrounding existing natural ground level. i. Source of soil will be from various offsite locations used by land developers contracted to Whitehurst Sand, Inc., who need removal of unneeded clean soil from their location. Whitehurst Sand personnel will also bring in clean soil fill from Whitehurst contracted jobs in the area. ii. Soil fill will be free of contamination from metal, plastic, rubber, wood or wood by-products,asphalt,concrete, land clearing debris,construction and demolition debris, medical waste,or municipal solid waste. III. All soil brought in to the Haskett Mine site will be generated from properties where there has been no known release of contaminants, and that is generally approved for unrestricted use. iv. No soil will be accepted from offsite properties contaminated by the release or migration of contaminants. v. Clean soil will be transferred to and stockpiled along the northern top edge of the Haskett Mine 6.4-acre excavation, where it will be leveled and then pushed into the pond with bulldozer and excavator. vi. As soil is placed in the pond, excavators, bulldozers, and other heavy equipment will compact the soil to form a firm base. vii. Over a period determined by market conditions, estimated to be several years, Whitehurst Sand personnel will continue to fill the pond with clean soil up to surrounding normal ground level.,working their way across the entire pond,and compacting the soil as they go. viii. Water level in unfilled portion of the pond is expected to remain the same during RECEN `.? the life of the filling period due to the relatively small amounts of fill added JUL 2 d 1823 compared to size of the pond and length of time taken to fill the pond. Pond water should have time to percolate naturally into groundwater level as filling LAND QUALIT occurs. MINING PROGRPM ix. If necessary,operator will pump remaining water from the Haskett Mine pond to prevent overflow around pond edges during filling operation. Pumped water will be transferred to an existing 0.93-acre foliated pond north of the Haskett Mine. This north pond was formerly used as a sedimentation pond, has an active NPDES COC permit #NCG020748, and has no overflow or discharge to Waters of the State. e. Soil fill brought in to the site will be regulated by Whitehurst Sand personnel who will monitor the soil for contaminants that are not acceptable as beneficial fill at Haskett Mine. f. Once the excavated pond has been filled with soil up to the same level as that of normal surrounding ground level,Whitehurst Sand personnel will continue adding soil to the site and form a 2-ft tall, ridged mound in the center of the former excavated area with slopes tapering to natural ground level at the edges. Peak of the ridged mound will be 200 feet from all former edges of excavation. g. All soil placed on the site will be compacted by heavy equipment as slopes are formed. h. After construction of the mound and slopes,operator will grade the mound for evenness and then sow groundcover grasses per State guidelines. L All other affected areas inside the permit area will be graded, levelled, and sown with groundcover grasses. j. Former sediment pond, which has been unused for several years, currently has full- growth foliage and woods surrounding it. Foliage will remain and be maintained by the owner. k. Operator will leave a 12-ft wide dirt field path around the cleared and grassed area. I. After reclamation,area will revert to a natural grassed area suitable for wildlife habitat.
