Three well nests of three wells each were <br />plugged with cement from TD to just below the surface. Plugging was performed by Western American <br />Drilling and was supervised by Grevstone stall and Gene Dillisham of [he Bureau of land Management <br />Cement was mixed in 80 gallon and smaller batches and pumped downhole through 2-inch tubing or tremie <br />pipe. The tremie pipe was lowered to within ten feet of TD and a batch of cement was pumped. Then the <br />pipe was raised up and subsequen[ batches were mixed and pumped. The PVC casing was broken otf <br />three feet below the ground and cement was pumped until it was one or two leer from the surface. <br />Af[er the cement hardened dirt was shoveled on top of the site and raked to eliminate large mounds. <br />All trash was taken off site and disposed ot. Wire mesh and rebar protective cages, used to protect the <br />wellhead, were given to the BLM for their future ttse. <br />A well abandonment report is attached (or your review and approval <br />Reseeding also occurred during this period on a bald area on the top of the ridge between Ponds #002 <br />and #(x13. The ground was hoed and broken in order to trap seeds and to prevent removal by surface <br />runoff and strong winds. Approximately 45 pounds of the approved reclamation seed mix was applied. <br />Well sampling waz done for wells 1, lA, 1B, 1C, 2 and 7; and the samples were taken to Core Labs for <br />cheminl analysis. Samples were obtained for all wells excep[ for well 2, which was dry. <br />Thanks for vuu: time and aaeutiun. <br />Sincerely, <br />Iezry H.
