Since this particular AVF falls under <br />the exemption to the interruption of farming, the essential hydro- <br />logic functions of the AVF must be reestablished (if they will be <br />affected) and preserved (if they are outside the area to be <br />affected) (per Section 4.24.2 of the Colorado Rules and <br />Regulations). It should be reemphasized that since the AVF ident- <br />ified in UTL Site area is not significant to farming by virtue of <br />the exemption, the essential hydrologic functions of the AVF may <br />be affected during the mining operations;Yl~ev ,~ 'n <br />mi g_,a,.~,h~.e~s.e-:~umct~ons ~-an>3+s - d to a cond~iti.o:n.,,(.in terms <br />o~...,~!dtes„ .gfil~ar~,t,i<.tv.::aad ot~a:a.;r.,v..i.~ e~mmnarah,lo to that~..whaao~h~~••existed <br />pr,~o~to ., th,,,.e;~;•ex~st~e.nce: af~U-TL.
