Borehole Information Update ]an. 29, 2002 Page 2 ownership remains unknown. BLM correspondence dated August 12, 200] listed 17 Ken- wells in the exploration license area. Two of the wells aze most likely owned by the USGS (DH-5 and DH-G) and Ken should not be responsible for reclamation of these wells. The current count For Kerr wells in the Exploration License Area is ] 5. There are another G wells likely owned by USGS. Drawing BLM-2, Marr Mine Area Exploration Boreholes/Wells, provides an up-dated inventory of the wells in the Marr Mine Area. Another round of field reconnaissance is planned for the spring of 2002. Boreholes/wells will be marked and flagged to facilitate field location for reclamation activities. Additional information may be collected during the reconnaissance effort such as GPS coordinates, water levels, and total depth, which may provide additional insight into well ownership and final abandonment requirements. Information in the project fdes indicates that two wells, AO-2 and AK-2, previously reported as destroyed, were located during the previous field inventory efforts. If the planned field reconnaissance confirms that these wells exist in a condition that allows abandonment, they will be reclaimed as pazt of the program. The plan for sealing the wells and Boreholes was previously provided as the Borehole Reclamation Plan submitted January 3, 2000. This plan is consistent with the CDMG Rules and i1,~ ~) I ~~l ,/ ~ ~1~ ~~ ~) JIL ~ 1 5 1 I f ~,~r L ~~t , v'' Regu]ations for Surface Mining (4.07). Final plugging requirements for each borehole/well will be determined based on existing information or supplemental information collected during the field reconnazssance component of the borehole reclamation plan and will reflect consideration of whether or not a known aquifer was encountered in the well and if confined or unconfined conditions are present. Tables 1 and 2 present the preliminary plugging plan for each borehole/well based on cuaent information. Additional evaluation of each well will be completed in the field and final plugging methods may be modified as appropnate. An evaluation of the well information and characteristics identified several wells with potential future benefiaal uses. The wells with potentitia3 future beneficial uses are listed below. • Current water quality monitoring - 79-1, 79-2, 79-3, 79-G1, AO-2A and SP-Ol (new well) • Future coal exploration or production - DH-3B, DH-5, DH-G • Possible water wells - 79-G0, 80-2, 80-] 1, BLM 20, water supply well (at office) Wells 79-1, 79-2, 79-3, 79-G1, AO-2A and SP-Ol are currently monitored, so they ~vdl be abandoned based on water quality monitoring results under specific recommendations. DH-3B, DH-5 and DH-6 ([JSGS wells) may be useful for future development of coal. Several wells have been identified as possible water wells. The most promising wells are listed above. Other potential water wells include 79-7, 79-23, 79-27 due to long screened intervals and relatively shallow depth to water. 'T'hese wells, however, have a smaller diameter casing (2-inch PVC) so additional testing relative to their suitability as water wells may be appropriate prior to a final recommendation. The wells identified with potential future beneficial uses are indicated on Map BLM-2, Mazr Mine Area Exploration Boreholes/~~/ells.
