-L ~I~ XV 1 i 1. ~ SULtSIi)EItlCE - BULLS 2.05. 6(b) aria 4.2G CRiTICA'~ CUI~CERhS - The ite~„c of criCical concern in this section are of importance os they relate to the discussion of probable hydrologic consequences. These are: (a). The statement on page IV-43 that "minor settling ui' strata in the AVF will not diminish the farming capability" is C~'~~~ ~ unsupported. Empire Energy Corporation roust demonstrate that ,r'OM\'~_ this statement is warranted. To do this the applicant will have to identify the hydrologic functions cf the AVF as stated in the section amJ deterarine the effects of subsidence on these hydruluyic fwi~Liuu•s. ~ (V). The section on "Description of worst Possible Consequences" must contain a description of wurst possible Consequences Fur m•ixi~i~w~i subsidence beneath both the Ya~upa and Willia~us Fork lovers and alluvial aquifers. The information is required to detennine to ~ probable hydrologic consequences of mining as discussed in tnat section. , (c). Un page IV-142 the applicant states that "in the event of material damage to the irrigation ditches, they will be ~ repaired". Empire Energy Corporation must co~ronit to~~naintaininy (~o the irrigation syste~» in a "functional condition". S7IPULHT?U'1S - Tnese concerns could ue stipulated as conditions to the permit. 7hrouyhout Section 4.6, "Subsidence Control Plan", of Lhe amended application, an inconsistency exists concerning which areas of the mine plan will be the subject of partial extraction. The applicant indicates in various sections of the application that the Williams Fork and Yampa Rivers will oe protected from subsidence occurrence through liritation of mining beneath the rivers. Uther sections of the application ,.odressiny control of subsidence fail Co mention the rivers. This ambiguity roust ue resolved i~ order to avoid significant future probla,~~s for the applicant. It is the Division's understanding that the "BUFFER ZOIVES" lightly depicted upon Flap IV-1 are those areas within which the applicant pro,~o5es to lin;it extraction Cu rounr and pillar develop+nent upun advance. Ail references listed hereafter should Ue a.»ended to read clearly and unambiguously in ay reeR:ent with that understanding, as stated c,i pagc- I'.-14d of SeCtirn 4.6.3.2.
