In response to a request by the CROW, American Soda will construct the project pipeline on the east side of the existing pipeline corridor for at least 2 miles on either side of the known active sage grouse lek on Barnes Ridge. To enhance sage grouse habitat, shrub and fort species !mown to be beneficial to sage grouse may be included in the pipeline corridor revegetation seed mixture within the Sage Grouse Treatment Area (see Section 3.4.2). Construction timing limitations will be in effect within the Sage Grouse Treatment Area to protect sage grouse breeding and nesting activities. Ground-disturbing pipeline construction activities within 2 miles of known active sage grouse leks on or neaz Barnes Ridge would be scheduled to avoid the critical activity period (from Mazch 1 through July 1). This includes the entire Sage Grouse Treatment Area of the pipeline corridor. However, the CDOW and the BLM have agreed that unlimited access along Sprague Gulch Road would be allowed. Preferably, all project traffic would use the Sprague Gulch Road access. Certain low-intensity activities (e.g., surveying) may lie allowed within the Sage Grouse Treatment Area during the April 1 through June 1 period, subject to the written conditions and approval of the BLM in coordination with .the CDOW. 3.24 Visual Screening • Approximately 12 miles of the proposed pipeline corridor are visible from public roads. The additional pipeline corridor will not substantially change the visual impression along most of the corridor. However, American Soda may reduce visual impacts using techniques such as slope restoration, selective clearing of adjacent trees to reduce contrast, mulch/native seed planting, and matching slope protection fabric with the native soil color, if required by the BLM. The technique of selective clearing could be used on specific portions of the project if requested by private landowners. 3.25 Weed Management To prevent the introduction of noxious weeds into the disturbed azeas, all construction equipment will be thoroughly cleaned before entering the project azea. Parts of the construction equipment that are in contact with the soil (blades, buckets, crawler tracks, tires, etc.) will be washed or otherwise cleaned of all soil. Construction equipment will also be washed or otherwise cleaned, of all soil after having been used in azeas with identified noxious weeds. Noxious weed locations will be surveyed prior to construction, and azeas with noxious weeds will be treated prior to rnnstruction. No aerial spraying will occur within the Sage Grouse Treatment Area in order to minimise potential impacts . on desirable (orbs and shrubs preferred by sage grouse: Pipetaie Plan of Development 19 Yankee Gulch Sodium Minerak P~vject Amman soda.
