~" FONSI <br />CO-200-2006-0056 EA <br />The environmental assessment, analyzing the environmental effects of the proposed action, has <br />been reviewed. The approved mitigation measures result in a Finding ofNo Simificant Impact <br />on the human environment. Therefore, an environmental impact statement is not necessary to <br />further analyze the environmental effects of the proposed action. <br />RATIONALE: No significant impacts were identified by this analysis and mitigation measures <br />will eliminate or reduce impacts to acceptable Levels. <br />DECISION RECORD <br />DECISION: It is my decision to authorize ACA products to develop a gravel pit on public lands <br />below the Trout Creek Reservoir as described in the proposed action. <br />( RATIONALE: The gravel pit will be located below Trout Creek Reservoir in a location that <br />contains silt, sand, and gravel primarily derived from flood events in Trout Creek in the eazly <br />1900's, particulazly a 1924 flood event. Over the last 50 years, Trout Creek (upstream of the <br />reservoir) has gradually been transformed into a relatively stable stream with well established <br />stream side vegetation. Additionally a reservoir was constructed immediately upstream of the <br />' proposed gravel pit location to help control stream flows as well as providing a source of <br />irrigation water in the area. <br />Trout Creek no longer exists as a stream from the Reservoir to the Arkansas River where it once <br />flowed, a distance of approximately three miles. Downstream of the reservoir there are now <br />three irrigated fields which also have become popular habitat for deer primarily in the fall and <br />winter. <br />The gravel pit on public lands will provide two primary benefits. First it will provide gravel and <br />general fill for the market. Secondly it will slow winter water flows from Trout Creek Reservoir <br />and allow the water to infiltrate back into the local ground water table. This will minimize <br />flowing water which causes damage to the down slope irrigated fields. <br />The BLM was concerned with potential flooding in the winter and if any water rights issues <br />would be impacted. A meeting was held with Dave Kelly, deputy water commissioner of water <br />district 11, on May 25, 2006 to discuss these concerns. Also attending this meeting were <br />representatives of the ACA Products. Following this meeting, the following individuals visited <br />the site location on June 15, 2006 to discuss the water concerns: <br />• Dave Kelly -Deputy Water Commissioner, Water district 11 <br />21 <br />
