BUFFER ZONES <br />As shown on the Map ?-9, subsidence buffer zones have been designated in the <br />• Stevens fulch and East Roatcap drainage basins. Entry ways will be driven <br />throuyh the buffer zones as required, CWI proposes water mitigation plans for <br />that inflow water due to those entry ways, <br />MONITORING <br />CWI proposes a detailed mine inflow monitoring to be conducted annually, This <br />report will be submitted and the theoretical calculations confirmed for actual <br />water inflow, This mitigation plan will be revised based on the actual inflow <br />experience. <br />RFPAiRS <br />No repairs are anticipated for natural seepage due to inflow. Because of the <br />transmissivity of the coal seam itself and natural fractures, repairs are not <br />possihle. <br />IMPROVEMENT OF TRANSPORTATION SYSTEMS <br />CWI will work with the local water users to improve water transportation systems <br />on a case-by-case basis. An improvement in the transportation system can in- <br />crease the useable flow. In this way, even potentially immeasurable water loses <br />can be mitigated in advance, CWI will consult with the regulatory ayencies on <br />• these case-by-case improvements. <br />REPLACEMENT WATER <br />The Stevens Gulch inflow is anticipated at 5.7 gallons per minute, C4iI proposes <br />that, if necessary for vested water users, replacement water will be furnished <br />from the Stevens Gulch Well Field - Orchard Valley Wells kl, 7, 3, and 4, f,WI <br />is currently decreed for 40 acre-feet in this well field, Current usage is 11 <br />acre-feet, leaving approximately 30 acre-feet for replacement purposes. CWI <br />would pump 5.7 gallons per minute into Stevens Gulch if required by water us- <br />ers. <br />Within the East Roatcap drainage, 5.4 gallons per minute would need to he re- <br />placed. CWI proposes West Reservoir water to be delivered during the irrigation <br />season only. As is stated in the subsidence-induced water replacement plan, CWI <br />has ?3.63 acre-feet for potential water replacement. The water replacement po- <br />tential for mine inflow in East Roatcap would amount to approximately 5 acre- <br />feet of this water right. <br />OTHER ALTERNATIVES <br />CWI will continually evaluate other sources of water replacement such as water <br />storage ono vegetation manipulation. If a technologically better alternative is <br />• available, CWI will adjust this plan for that alternative. <br />
