<br />Banks and Gesso, LLC <br />EXHIBIT D -MINING PLAN <br />Overview <br />The applicant proposes to develop the site as a sand and gravel mining and <br />processing operation with ancillary and compatible uses of asphalt and concrete <br />production. Approximately 78 acres of the total permit area acreage of <br />approximately 85 acres will be mined (see Exhibit C, Pre-Mine and Mine Plan <br />Map). The Lupton Bottom Ditch will be temporarily re-routed, mined-through and <br />reconstructed with concrete lining, and two sets of oil and natural gas pipelines <br />will have either been abandoned prior to mining the area in which they are <br />located or will be relocated to maximize aggregate recovery and final water- <br />storage capacity. Agreements are being developed with the owners of these <br />structures to accomplish this plan. After mining is complete, the excav~.tesl_area <br />will be reclaimed as two connected.water_sYorag.e_reservoirs~ufroaRded-bjc-an <br />engineered, impermeable bentonite slurry wall that will be emplaced prior to <br />mining. The two water-storage reservoirs will be separated by the replaced <br />Lupton Bottom Ditch, located north/south through the middle of the site, but with <br />a pipe and valve arrangement connecting them to enable separate filling and <br />drawdown. The linked reservoirs will be isolated from the alluvial groundwater <br />system by an impervious shale bedrock base and the slurry wall. The edges of <br />the reservoirs will be reclaimed to an irregular shoreline with wetland vegetation <br />gradually establishing itself. The post-mining land use of the property is for water <br />storage and wildlife habitat. The Reclamation Plan assumes the cost for <br />Ft.
