Rifle Gravel Pit #1 March 2n21 <br /> directly impacted. The Mexican spotted owl relies on deep shaded canyons, typically with <br /> closed canopy forest: there is no habitat for this species in the project area or regional <br /> surroundings. <br /> Fishes: The Colorado River adjacent to and downstream of the project contains potentially <br /> occupied habitat for the four endangered fish species, and designated Critical Habitat for the <br /> pikeminnow and razorback sucker is located approximately 5 miles downstream at the Rifle <br /> Bridge. The water depletions associated with the project have the potential to impact the <br /> four fish species and would trigger consultation requirements with USFWS. There are <br /> temporary depletions associated with the operation of the gravel pit, and there are <br /> permanent depletions associated with evaporative losses from the reclamation pond. SGM <br /> is developing an augmentation plan that would offset both temporary and permanent <br /> depletions from authorized sources, and that would maintain the existing water conditions in <br /> the downstream habitats. <br /> Flowering Plants: Debeque phacelia is limited to and badland exposures of Wasatch <br /> formation; there is no such habitat within the project area or surrounding vicinity, and no <br /> potential for this project to affect the phacelia. The project area does contain low-elevation <br /> open wet meadows that constitute potential habitat for Ute ladies-tresses orchid. The <br /> nearest known populations of the orchid are located in the Roaring Fork Valley in the vicinity <br /> of the Iron Bridge neighborhood of Glenwood Springs, approximately 30 miles upstream <br /> from the project. Repeated surveys of suitable orchid habitat in the Colorado River valley <br /> have failed to locate any orchid populations outside the Roaring Fork, therefore it is unlikely <br /> that the species would occur on the project location. However according to the interim <br /> survey guidelines (USFWS, 1992)the portions of the property that consist of wet meadows <br /> that are not continuously inundated and not dominated by cattails/bulrush/reedgrass do <br /> constitute potential habitat. These areas of potential habitat are limited to portions of the pit <br /> proposed for potential future development on the western portion of the property. There is <br /> no suitable habitat within the initial development area of Stages 1-2 and the dewatering <br /> pipeline. <br /> Orchid presence/absence surveys can only be conducted during the blooming season (late <br /> July through August). Given the existing database of negative survey findings in the <br /> surrounding area and the absence of habitat in the initial development areas, SGM <br /> proposes to evaluate habitat suitability within the western portion of the parcel at a micro- <br /> site scale during the proposed quarterly wetland monitoring. Areas that are identified as <br /> highly suitable based on the USFWS interim guidelines would be further evaluated during <br /> the blooming season for the presence of orchids. No disturbance to suitable habitat would <br /> occur prior to such a habitat suitability analysis, in concert with a formal orchid survey if <br /> warranted. <br /> 4.5 Colorado Parks and Wildlife Consultation <br /> Scott will leave the construction perimeter berm in place along the east, north, and western <br /> portions of the mined areas for the reclaimed condition. Note the height of the berm may <br /> change to achieve a balance for prohibiting fish passage on/off the property and safe wildlife <br /> access. See the Sheet C8 of the Drawings in Attachment A. <br /> Scott's Reclamation Plan (included in revised drawings, attached, Sheet C8) shows a <br /> Typical Detail for the pond with a maximum 3:1 slope for the submerged portions of the <br /> pond (based upon the estimated groundwater levels). <br /> 9 <br />
