determine curcent groundwater conditions, levels. direction of flow and quality by installing, measuring <br />and sampling mondoring wells near the sand and gravel extraction area The program currently calls for <br />the installing o1 three mondonng wells to detennme the effects on the ground water table dunng periods of <br />mine de-watering. The water level in each will be mentored and recorded on a monthly basis beginning <br />upon the completion of the well and will continue until the sand and gravel extraction process has ceased <br />In the event that draw down of the water table is greater than two feet in the wells adjacent to the sites <br />west boundary. remr:d+al activities could then be planned, such as, reducing pumping rates until the water <br />level in the mOn+lOnng wells return to an acceptable level. <br />The first step of the mirnng process Mnll be the removal of zero to six inches of topsoil The topsoil will be <br />removed using scrapers, loaders and dump trucks and stored m stockpiles surround+ng the +dentihed <br />extraction area and w+ll be used during the reclamation phase of the mine. Once the topsoil) has been <br />removed, the overburden removal process will begin As was the case with the topsoil removal, <br />overburden will be excavated to the lop of the sand and gravel resource using scrapers, loaders, and <br />dump Irucks. Overburden will also be stockpiled adjacent to the topsoil stockpiles as well as wdhm the <br />extrachon area Overburden that will not be used m the reclamation efforts described m Exh+Wt E and <br />Exhibit F will be removed from the site for use as structural fill. To prevent erosion, all o! the stockpiles <br />adjacent to the extraction area will be hydro- seeded wdhin 12 months of establishment al a rate of 15 <br />bulk pounds per acre.
