• Raptors: A raptor nesting survey was completed by Cedaz Creek Associates during the 1998 raptor nesting period for all public land portions of the pipeline corridor (Cedaz Creek 1998). American Saia will conduct additional raptor surveys of suitable habitat along the pipeline corridor in areas not covered by the 1998 surveys. These additional surveys will be completed prior to pipeline construction. In addition, any inactive nests identified along the pipeline corridor during the 1998 surveys will be checked for activity prior to initiation of pipeline construction activities. If any nests aze determined to be active or if any previously unidentified active nests are discovered during construction, construction activities would be subject to the following BLM stipulations. 1) For any active nest discovered along the pipelu>e corridor, a no surface occupancy (NSO) zone will be established around the nest, whereby disruptive surface occupation or adverse habitat modification would be prohibited within one••quarter mile of functional nest sites of special status raptor specze;o and within one- eighth mile of nests of other raptor species. 2) Timing limitations (TL) would prohibit all development activities within one-half mile of functional nest sites of special status raptor species and within one-quarter mile of nests of other raptor species from February 1 to August 15 or until fledging and dispersal of young. Exceptions, modifications, or waivers to the NSO and TL stipulations consistent with the White River Resource Area Managernent Plan may be allowed by the BLM based on consultation on a site-spe+sfic basis. Raptor NSO and TL stipulations aze provided in Attachment 4. • Sage Grouse: In response to concerns of the CROW and BI.M, American Soda has prepared a Sage Grouse Mitigation Plan, which is contained in the Wildlife Mitigation Plan The Barnes Ridge portion of the pipeline corridor is of particular concern due to known leks and nesting and brood rearing habitat in this area. For purposes of the Sage Grouse Mitigation Plan, the section of the Yankee Gulch Project pipeline corridor from the pinyon-juniper/sagebrush transition zone on the north end of Barnes Ridge in Section 27, T3S, R96W (approximately MP 19) to the divide area in Section 34, T4S, R96W (approximately MP 2~ is considered to be occupied sage grouse range and will be referred to as the Sage Grouse Treatment Area. 7~e total length of this segment is approximately 8 miles. elan of Devdopmert 18 Yankee Gulch Sodiw~ Ma~mis Project Amnion Soda, LLP.
