SEALING OF EXPLORATION HOLES. OTHER BOREHOLES OR WELLS <br />• The following abandonment plan is proposed: <br />1. Non-Aquifers - Backfill with cuttings to ten feet below the <br />surface. Insert a spider, or other suitable, plug at ten feet <br />and fill with cement to three feet below surface. Cut off the <br />well casing three feet below the surface, and backfill the hole <br />to ground level. <br />2. Non-Artesian Aquifers - Seal with a solid cement plug <br />twenty feet above and below each aquifer. Insert spider, or <br />other suitable, plug at ten feet and fill with concrete to three <br />feet below surface. Cut off well casing three feet below surface <br />and backfill hole to ground level. <br />. 3. Artesian Aquifers - Seal hole with cement from bottom to <br />within three feet of surface. Cut the well casing off three feet <br />below the surface, and backfill the hole to the ground surface. <br />4. All sites will be temporarily marked with a wooden stake to <br />allow MLRD inspection. <br />• <br />532 <br />
