Mr. Jim Stover August 9, 1996 -New App./Bowie 2 Page 5 iv) The application indicates that seven groundwater monitoring locations were not observed until June or July 1995. These locations should have been monitored also in April as recommended during the April 1995 meeting. Please provide Aptil data for either 1995 or 1996. v) Three alluvial wells downgradient of the proposed loadout were not installed as recommended. This recommendation was made to ensure proper baseline data collection. Provide specific well installation plans including proposed completion specifications, and mapped locations. These wells will be required for long term monitoring, as well as for the required baseline data. Such wells are also recommended for locations downgradient from the refuse pile. How will BRL ensure that the wells wID be installed and monitored to provide baseline data which is undisturbed by mine-related activities? vi) The Rollins sandstone well DH-34B is not ideally situated to detect mine-related impact; however, monitoring of this single Rollins well will be sufficient until such time as BRL intends to permit mining in the B-2 coal seam, or if other mining proposals are made. Based upon information provided by BRL, it appears that typical Rollins water piezometric surface projections are several hundred feet below the D-2 seam currently proposed for mining. Monitoring as proposed with this application is acceptable. However, the B-2 seam may be within the artesian zone emanating from the Rollins sandstone, and communication with future B-2 seam workings through faults could be possible. Additional consideration will be given to further Rollins sandstone monitoring, both baseline and operational, if and when B-2 seam mining is proposed. vii) The completion diagrams for wells DH-54 and DH-55 state that a portion of the casing is slotted while the remaining portion is solid. However, the stippling in the drawings shows that the entire casing is slotted. Please reconcile the difference, and revise the submittals as need. viii) V/e acknowledge that well DH-55 should monitor the perched water zone located above the lower B coal seam. This information is of value, and will be required. Monitoring of the aquifer below the coal seam to be mined is mandatory. Please explain why additional wells are not proposed for the perched zone below the D-2 seam. Typically, three wells arc needed to ascertain impacts, both upgradient and downgradient. Please provide such a plan.
