deer habitat lost. or made unavailable over each 5-year period, Erom the first year of development through the end of mine life (Environmental Consequences, Hule Deer). Specific practices that would be considered • include, but are not necessarily limited to: a. Mechanical brush manipulation b. Range seeding c. Prescribed burns d. Water developments The performance goal for mule deer habitat mitigation shall be to replace forage resources effectively lost over each 5-year period. BLH and the designated operator/lessee, in coordination with the Colorado Division of Wildlife, will appraise habitat losses, determine habitat enhancement needs, and formulate project methodology and design. All mitigation work will be subject to the approval of the BLH. 6. The designated operator/lessee shall be responsible for conducting annual raptor breeding a~:tivity inventories in pinyon-juniper habitats affected by well field dev~alopment through mine life. These surveys shall be conducted by qualified personnel with demonstrated training and practical field experience in raptor behavior and breeding biology. The surveys will be conducted during Hay or June of each year and will encompass a study area which is comprised of that portion of the well field which would be affected 2 years in advance of current mining activity and a 500-foot buffer around the principal study area. Results of annual inventory will be furnished to BLH by September 1 of each year. The designated operator/lessee shall be responsible for executing emergency oc remedial mitigation for newly initiated or previously undiscovered raptor nesting activity jeopardized by well field development, as directed by BLM in coordination with the U.S. Fish and Wildlife Service. 7. No unnecessary removal of pinyon pine or Utah juniper trees or snags will be allowed within the well field, particularly in that area between wells comprising a well pair. One year prior to preparative clearing of sites within the well field, individual trees which require removal must be identified for inspection and their removal approved of by the authorized officer and/or White River Resource Area wildlife biologist. ARCHAEOLOGY/PALEONTOLOGY 1. In consultation with the Colorado State Historic Preservation Officer (SHPO), it has been determined by BLH that the following sites: SRB2500, 5RB1923, and SRB410, are potentially eligible for listing on the National Register of Historic Places (NRHP). It has also been determined that further data collection will be required to make a final determination of eligibility for these sites. Therefore, before beginning any construction which could affect these sites the lessee must, at its expense, collect sufficient data to enable SHPO to make a determination of eligibility. The contractor selected to gather this information must have a valid BLH permit and all testing plans must be reviewed and approved by BLM and SHPO prior to initiation of any excavations. 15
