=! llu-.'ia! 'ialle,i f cor consideration <br /> C ` id-Continent believes that a negatizie deter- <br /> urination shcul c be made as to ,cf ether or not the area of the <br /> land to be a= � ac =ed O,,7 the .Coal jasin _..inin- oDerationS iS <br /> in, adjacent to , or under an alluvial valley floor . Such a <br /> determination is cased on the following with respect to the <br /> areas above or near th-e Coal basin underground minin-- operation : <br /> - no unconsolidated strea.�ilaid devosits holding streams <br /> are present in or adjacent to the permit area greater <br /> than the minimum valley width criteria (50 ' ) . <br /> - no caoacity exists for flood irrigation, based on <br /> strew;!-= .ow ?eater vield , soils , water qual' iry , <br /> topography and re`74onal practices <br /> - no suoirriga:ion of the lands in question is possible, <br /> Cdrained from the around water system of the valley <br /> floor <br /> - the historic and present use of the lard has been <br /> limited to undeveloped rangeland . <br /> Tt is further believed by the applicant that the <br /> information prosided in Chapter =T_T , Environme:tai Rescurces <br /> Information, . is co-,Ppletely adequate for the reviewing <br /> authorities to make t^e=r assesBSient of the nes-ative deter- <br /> mination claim D' 'Mid-Continent . <br /> Additional Comment : An assessment of AVF was made by the local <br /> SCS office who visited the site . Perhaps we should define <br /> alluvium. Sand , clay and rocks , etc . deposited by flowing water . <br /> There is alluvium in Coal Basin and east :Muddy Creek drainages . <br /> But these drainages are extremely steep and subject to frequent <br /> scouring . Little or no soil as such exists . The major surface <br /> being rocks , sand and gravel .
