3. No springs or seeps have been noted associated with the fill. <br />4. The Streeter Fill Inspection Reports contained in xhibi 6 document there has been no <br />significant changes noted in the survey monuments, the piezometer well and no formation of <br />any springs ar seeps. <br />Various surface cracks in the topsoil insulting from minor topsoil settling have previously been <br />noted and monitored, but no evidence ofsurficial slope failure or additional movement has been <br />noted. In summary, no significant changes have occurred in 1995. <br />B. Section 16 Fill <br />During constnrction of the Section 16 Fill, the Division received copies of quarterly inspection reports <br />and certifications for the Fill. The Division was notified in the fourth quarter, 1994 report that <br />"construction" ofthe Fill was completed and Colowyo was entering the "monitoring" phaze of the Fill. <br />As such, the certified inspections, piezometer well testing and monitoring of the 4 survey monuments <br />will be conducted quarterly and submitted only in Annual Reclamation Reports. <br />Reso_onse <br />• 1. The 1995 survey information, certifications and piezometer well information is located in <br />Exhibit 7, Section 16 Excess Spoil Fitl. <br />The survey infomrabon consists offour quarterly surveys of the four monuments accompanied <br />with corresponding charts to provide an analysis of the results. The surveys indicate the fill has <br />settled an average of 0.22 inches with a corresponding lateral movement of 0.21 inches north <br />and 0.06 inches east. The data indicates nothing more than the anticipated amount of settling. <br />2. The piezometer well was established in late 1994. A water level has been detected at the 60 <br />foot depth which corresponds to the level at which the drill penetrated consolidated material <br />underlying the rock drain. We interpreted the water level to be located at the interface of the <br />bottom of the rock drain and the underlying strata Subsequent monitoring has shown the <br />water level to remain consistently at the 59,1 to 60 foot depth. <br /> <br />4 <br />
