Vantage to Pomona Heights Chapter 2 230 kV Transmission Line Project FEIS Proposed Action and Alternatives PAGE 2-54 VIS-7: Whenever possible, locations of the new structures will match the spans of adjacent transmission lines and structures. 2.3.6 Cultural Resources CUL-1: Pacific Power will implement stipulations and standards of the Project-Specific Programmatic Agreement (PA) prepared and executed by the BLM and JBLM YTC, Reclamation, BPA, FHWA, Washington State Historic Preservation Officer, Pacific Power and other interested parties according to the requirements of Section 106 of the National Historic Preservation Act and its implementing regulations (36 CFR Part 800). The PA will define the Area of Potential Effects (APE); procedures for identifying cultural resources within the APE; evaluating their significance; assessing effects; avoiding or mitigating adverse effects; emergency discoveries; reporting; Native American consultation; and other topics. CUL-2: Pacific Power will oversee an intensive pedestrian cultural resource survey on all federal and state lands and on private lands where easements have been acquired or permission of the land owner has been granted prior to survey. The survey will be conducted within all areas of possible physical disturbance within the APE of the final selected alternative under BLM’s direction and following BLM manual guidelines. The APE for the undertaking includes all involved federal, state, and private lands and is defined as follows: • The transmission line’s direct APE shall be a 500-foot wide corridor, 250 feet on both sides of the transmission line’s centerline. • The direct APE for any existing access roads in their current condition, existing roads that will be improved as part of the Undertaking, and newly built roads shall be a 100- foot wide corridor, 50 feet on both sides of the existing road or proposed road centerline, plus a turning radius of 60 feet where specified. The 100-foot corridor may be wider in some locations to allow cut-and-fill disturbance areas on a hillside, as required for safe construction access. The direct APE for material staging areas, pulling and tensioning sites, splicing sites, concrete batch plants, and other temporary use areas shall be the footprint of these areas, plus a buffer of no less than 50 feet from the construction footprint • The APE for geotechnical drill sites shall be the boring location footprint, plus a buffer, no less than 50 feet, extending from the perimeter of the footprint. • The APE for indirect effects will extend no farther than 3.0 miles from the centerline of proposed transmission line ROW for the selected route. • Certain classes of visually sensitive cultural resources, such as TCPs, beyond the 3.0-mile indirect APE may require analyses to assess visual effect. The BLM will consult with the Tribes, DAHP, and other Signatories to determine whether a change in the visual APE is necessary for these cultural resources. CUL-3: Pacific Power, in consultation with BLM and the Consulting Parties, will develop and implement specific mitigation measures to mitigate any adverse effects. These may include Project modifications to avoid adverse impacts, monitoring of construction activities and data recovery studies. CUL-4: Prior to construction, all of Pacific Power’s supervisory construction personnel will be instructed on the protection of cultural resources. To assist in this effort, the Pacific Power will address: (a) federal and state laws regarding antiquities, including collection and removal; (b) the importance of these resources and the purpose and necessity of protecting them; (c) tribal concerns; and (d) methods for protecting sensitive resources.
