With the advances in computer technology, TCC is optimistic <br />bc[tcr resolution of the signal can be obtaitral and ibis will lx usW [o define the foul[. <br />The seismic program will entail establishing one line approximately 6.5 miles total length oriented <br />SW to NE starting nu-tr the center of Sec. 24, TSN, R87W and ending near the center of Sec.l2, <br />TSN, R86W as shown on the 1998 Notice of Intent Drilling Program map. 6-9 geophones will be <br />Paid out over fire line on 25 foot centers to record the data. Drill holes wits be estahlishrYl on 150 <br />foot centers over 6 miles of the line. The geophones may extend 1,320 feet past dte ends of the 6 <br />mile long shot line. Thc drill holes will be approximately 20 to 22 feet deep and will have a <br />nominal diameter of 4.5 inches. The cuttings from the drill holes will be mixed with bcutotrite drips <br />to be used as stemming over a 1 pound biodeSradablc charge that will be placed in the bottom of <br />the hole. Thc holes will be drilled witJt a small auger drill rig mounted on tires or [racks. There <br />arc no plans to construct any roads to aid in Ure drtlting of the holes. Thc rig is sufficirntly mobile <br />to eliminate the need for road building activities. All fence damage will be repaired immediately <br />upon completion of the seismic lines. Upon completion of the pro};ram the shot wire. marker <br />stakes, survey flagging, left over supplies, all trash, geophoncs and cable will be recovered. Based <br />upon the limited dtpth of the holes and fire fact that the cuttings will be used to backfill the holes <br />prior to shooting, no further rcelvttation work is planned. <br />1'he backhoe test pit corridors are lowtcd within the Fish Crcck valley floor. Thc purpose of the <br />test pits is to provide additional soils information within the valley floor. Ai pot rite attached map, <br />there are four corridors where the tts[ pits will be excavated. Within each condor up to four test <br />pits will be e.cavated for use in describing the soil prof Ic, rooting depth, subsur(atx yreology and depth <br />ro water. The pits wirl lx approximately I s to 2u feet in depth , 2 to 3 wide and approximately 10 feet in <br />length. The excavated material will be placed adjacent to the pit for use in reclaiming rite pit. <br />Reclamation Plan: Reclamation acttvrucs will begin once mud pits are sufficiently dry to allow <br />regrading of each site to occur. Materials excavated for the mud piu will be redistributed over dte <br />site, stockpiled topsoil will be spread, and broadcast seeding will occur over the entire disturbed <br />area using the following approved seed mixture Erom Permit No. C•82-056. Newly constructed <br />segments of access road will be reclaimed in a similar fashion with stockpiled topsoil spread and <br />disturbed areas broadcastsccdcd. <br />Stxcics <br />Slender Wheatgrass <br />Intermediate Whcatgrass <br />PubescentWhcatgrass <br />Desert Wheatgrass <br />Orchardgra_as <br />Seeding Rate {PLS Ibs/acrd <br />2.0 <br />2.0 <br />2.0 <br />1.5 <br />0.5 <br />Timothy 0.5 <br />Regar Meadow Brome 0.5 <br />Lincoln Smooth Bromc 1.0 <br />Alfalfa 0.25 <br />Cicer Milkvctch _ 0.25 <br />total 10.5 <br />09/23/78 4 of <br />
