u Pond FW-1 provides for water storage. Water can also be stored in Sediment Ponds MB-l, MB-2, and MB-3 under a separate decree. Storage is usually limited to the maximum sediment level elevation. Trans- fer to FW-1 is possible as outlined in the M & R Plan. Average withdrawals are not expected to exceed 400,000 gallons per day Activities (gpd). Flow may fluctuate depending on requirements associated with varying pro- duction levels. During 1993, the average withdrawal was 159,276 gpd for 250 work- ing days. This increase in usage can be attributed to more consistent operation of the longwall and the resultant increase in pro- duction.
