_17_ <br />which lie to the southeast of the fire Mountain Canal including the area <br />mapped Qpc are found to meet criteria of alluvial valley floors. Alluvial <br />deposits located upslope (northwest) of the Fire Mountain Canal failed to meet <br />the water availability criteria, and so were given no further consideration. <br />The alluvial valley floor along the North Fork continues downstream, as shown <br />on Map 5-2. <br />The operator will be affecting 11.45 of the Terror Creek watershed. This area <br />and the adjacent Terror Creek were not considered in the Division's original <br />Alluvial Valley Floor determination August 20, 1981 but they were considered <br />for this permit revision of June 20, 1985. The operator did not identify aqy <br />areas along Terror Creek that contain significant bodies of alluvium. Most of <br />the deposits are colluvial in nature and confined to the immediate stream <br />channel. The Morrell Camp area contains primarily colluvial deposits and as <br />such does not meet the definition of alluvial valley floors. <br />East and West Roatcap Creek were also not determined to be alluvial valley <br />floors. The sediments are predominately colluvial in nature and are too small <br />to support agricultural activities. <br />In reviewing the original application, some concerns were raised over whether <br />CWI proposed to use augmentation water that would normally supply an AYF. CWI <br />responded by showing that Terror ditch and West Reservoir waters supply Garvin <br />Mesa and an irrigated area known as "the Basin", both of which are out of the <br />valley floor canplex and are not alluvial valley floors. Therefore, CWI will <br />not be impacting an AVF as a result of augmentation mitigation. <br />Alluvial Valley Floors -Findings <br />The applicant is eligible for exemption from the requirements of Section <br />34-33-114(2)(e)(II) of C.R.S. 1973 by virtue of having a permit issued prior <br />to August 3, 1977. This permit was a License to Mine, issued by the Colorado <br />Division of Mines on December 14, 1976. This was the only primary permit <br />required at the time by Colorado law to operate an underground coal mine. The <br />real extent of this exemption must be based upon a demonstration of financial <br />or regulatory camnitment to mine prior to August 3, 1977. In this case, mine <br />maps submitted to the Division of Mines and information in the permit <br />application (see "Ground Water Investigation of Steven's Gulch" in Yolume 4) <br />provide the appropriate financial or regulatory demonstration. Therefore, <br />both areas identified as alluvial valley floors in Steven's Gulch and along <br />the North Fork of the Gunnison River are exempt from the requirements of <br />Sects on 34-33-114 (2 ) (e) (I ). The perms t re vision areas and the potential <br />alluvial valley floor in adjacent Terror Creek are not covered by the <br />grandfather provision, and will be discussed separately later. <br />Although exempted from Section 34-33-114(2)(e)(I ), the applicant must still <br />comply with Section 34-33-120 (2 )(j)(vI) for all activities which involve <br />surface operations or surface impacts incident to the underground portions of <br />the mine. To demonstrate compliance, the applicant must identify the <br />essential hydrologic functions of an alluvial valley floor and submit a plan <br />demonstrating that the essential hydrologic functions can be preserved <br />throughout mining or restored after mining. <br />The essential F~ydrologic functions of the AVF along the North Fork of the <br />Gunnison are both flood irrigation and subirrigation. The lower levels of <br />
