account for a second oil and gas well, so the existing proposal now labeled Tract <br />C is slightly smaller than that imagined in the October 2007 study, and <br />consequently will have even less potential for impacting surrounding lands. <br />In this instance, wetlands will be recharged during the extraction process by the <br />waters leaving the existing pond at the established irrigation gate on the west <br />end. Additionally, much of the delineated wetland is established from surficial <br />flows from the Last Chance Irrigation waters in the natural tributary entering the <br />wetmeadow pasture from the southeast. Subsequently, activities are not <br />anticipated to adversely impact wetland groundwater levels due to the surficial <br />recharge related to discharge waters from Tract C entering the pasturelands <br />from the established pond irrigation gate. <br />As a fall back, three tensiometers will be established within the root zone of the <br />wetland vegetation west of the influence from the established pond and below <br />Tract C as shown on the Revised Extraction Plan Map. The tensiometers will be <br />placed within the upper two feet of the solum as a minimum, or otherwise if <br />deeper, to the extent of the majority root zone. The tensiometers will indicate <br />field capacity during the growing season and will be monitored on a weekly <br />basis. <br />If field capacity is lost at any two tensiometer locations within four consecutive <br />weeks during the growing season then supplemental surficial irrigation of the <br />affected area will be introduced to the location of wetland vegetation, not <br />otherwise watered by the Last Chance Ditch tributary to the east, until field <br />capacities are restored and maintained for an equivalent period of four <br />consecutive weeks as determined by placed tensiometers. <br />5. How many pumps will be used to dewater Tract C? Please provide the <br />location of the pump(s) on the Mining Plan Map. <br />Only one pump will be utilized. The pump will be established along the northern <br />boundary of Tract C, and the waters will make their way through either <br />established, improved, or created ditchworks along the northern boundary of the <br />Tract until it exits at point DPC, shown as an orange triangle near the northeast <br />corner of the Tract and immediately south of the established farm pond. The <br />actual location of the pump will be updated in the required Annual Report. <br />6.4.12 Exhibit L — Reclamation Costs <br />Varra Companies, Inc. - M- 2009 -006 <br />July 2011 Technical Revision 4 <br />Kurtz Resource Recovery & Land Development Project Correspondence of 3 August 2011 <br />
