G <br />3. Describe the estimated topsoil depth and how topsoil will be salvaged, stockpiled and redistributed for the re-establishment of <br />vegetation. Specify approxinaatz topsoil redistribution depth: <br />TTze topsoil thickness is 6 to 18 inches. Mud pit excavation: stri~the <br />area to be excavated of topsoil and stockpile; excavate mud pit to the <br />prescribed dimensions and stockpile excavated material ;sperate from <br />top soil.'At drilling completion, the mud pits will be backfilled, first <br />with excavated overburden followed byystockpiled topsoil. <br />4. fescribe how drill holes will be plugged {refer to Rule >.~1 of the Rules for required abandonment procedures}: <br />Drill holes converted to_~roundwater monitoring wells w_tll not be .p lugged. <br />Exploration borings will be sealed using an Envirogrout abandonment fluid <br />mixture with a Marsh Funnel fluid viscosity of 65-75 seconds. The surface <br />will be plugged using 3/8" bentonite chips and the plug will be set zero <br />feet below the ground surface. Grout will be mixed to a Marsh Funnel <br />viscosity of > or = 20 seconds of bottom hole drilling jEluid viscosity <br />and then pumped from the bottom up. Bentonite chips wil:L be placed after <br />24 hours. <br />~. Describe how portals, adits, shafts, ponds, excavations, or other disturbances will be reclaimed (refer to Rule 3 and Rule ~ for <br />specific reclamation performance standards). You may wish to contact the Division for closure specifications. <br />Reclamation will consist of back-filling the mud pits (as described <br />in section 3 above) and grading the surface to conform t:o surrounding <br />grades. Th_e .surface of t_he back-filled areas will be crowned in the <br />center so runoff will not collect over the reclaimed muci pits. At <br />the conclusion of grading, the disturbed areas will be re-seeded. <br />(,. €~e:~;., ih=.' h.~w I'C7iii~S !t;i: I?C ~~Cl~tt}}~~:ai (7r r:'.:lii't~~ S ii' El?G;'." j~rt;-~,rtlc,~~U2~n? ?t~: la':;itt'i't i:,,il:l';tiCi:~: <br />No roads will be constructed as part of this prospectincq effort. <br />Minor disturbance to vegetation .resulting .f,rom .the .dril,]_ ,rig/backhoe <br />accessing the well site from the adjacent road will be repaired with <br />hand tools and seeded. <br />
