RULE 2 PERMITS SMINKSOM conditions averaging 25.1 feet from 13 measurements taken in 1996, 1997 and 2005 (Table 1 - Groundwater Parameters, from August 16, 2005 letter to Jim Stark from Walsh Environmental). • Active erosion in the stream channels is causing further incision and reduced flood frequency, reducing the ability of this valley bottom to support any agricultural use other than rangeland or dryland agriculture. There is no evidence of "modern terracing" in the area proposed for disturbance near the Gossard Loadout facilities. • Local and regional agricultural economics are prohibitive to developing irrigation projects within this valley bottomss, and such practices are in decline locally. • Historical irrigation activities associated with the "diversion structure and ditch" located hydrologically above the proposed access road path, diverted water around the existing grain fields, under County Road 17, outside the current permit boundary to the fields northeast of County Road 17. This activity was not recommenced after the mass wasting events (1983 -1984) disabled the functionality of the system. There are no plans to repair and put back into service this irrigation system in the future. • Colowyo contends that based on the descriptions and defining characteristics needed to classify an area as a functioning alluvial valley floor, the area proposed for disturbance associated with the Collom Access road in the area of the Lower Wilson Drainage no longer qualifies as an alluvial valley floor and should not require a material damage assessment, water monitoring program, etc. due to the fact the area is not a functional alluvial valley floor "pre- disturbance ". Colowyo does however plan to return the area of disturbance to pre- disturbance condition at the cessation of mining activities. 2.06.9 — 2.06.11 Augering, Processing Plants, In -Situ Processing See Volume 1 for these three sections. 2.06.12.1 Coal Refuse Piles Coal refuse piles do not exist on the Colowyo property. Thus, this section is not applicable. 2.07-2.10 VARIOUS Information required by these sections is included in Volume 1, in other sections of this application, in the cover letter or is not applicable to this proposed mine. Colowyo understands the permitting process employed by the CDRMS and will facilitate that process as requested. Collom — Rule 2, Page 134 Revision Date: 1/23/09 Revision No.: PR -03
