Carl Mount June 22, 1989 Page 3 was drilled to a depth of 970 feet and then plugged with cement to 650 feet (approximately eleven feet above the Lennox coal seam). The principal water yielding sands in the upper 650 feet of the well are from 335 feet to 430 feet. That places the producing zone about 220 feet above the Lennox seam. The average overburden aquifer saturated thickness in the area to be disturbed by mining that could feasibly be considered hydraulically upgradient from Olson's Well ranges from 5.6 to 46 feet. The average separation between the Wadge coal and the Lennox coal in this same area i s 40 to 50 feet. Thi s i ndi Cates that the O1 son Wel l i s plugged to a height in the stratigraphic sequence that is above that which is saturated and will be disturbed by mining at Seneca II-W. The particular sandstone portion of the overburden that the Olson Well derives its yield from is not even present (stratigraphically higher) in the upgradient areas 'to be disturbed by mining. There is no potential for mining to impact the quantity or quality of the Olson Well, and therefore, r~o mitigation plan • is required or warranted. With regard to the provision in Stipulation No. 6 pertaining to sending copies of the Augmentation Plan to water rights holders of record for comment, this notification is provided under several venues in the permitting process. First, the technical revision process provides public notice of both the application and the proposed decision by the Division. Second, with the filing of the Augmentation Plan with the water court, the court then prepares a resume' of the application which is mailed to all those who have ever expressed an interest in the vicinity or who appear on a general mailing list. The resume' is also published in the local newspaper. Finally, a water court referee is charged with providing a copy of the augmentation directly to all persons he believes may be impacted by the plan. At a minimum, this includes any entity mentioned in the plan, all property or water right holders of record in the vicinity of the plan, and any individuals who may have expressed an interest at some time in the past. These processes sufficiently satisfy the notification requirements of Stipulation No. 6.
