Proposed Action

Arizona Public Service Company (APS or Applicant) is proposing the development of approximately 38 miles of transmission line to increase the reliability of the high-voltage transmission system in the northwestern Phoenix metropolitan area. The proposed APS Sun Valley to Morgan 500/230kV Transmission Line Project (Proposed Action or Project) would establish a 500 Kilovolt (kV) and 230kV connection, constructed mainly on single-pole structures between two substations (the Sun Valley Substation [formerly called TS-5] and the existing Morgan Substation [formerly called TS-9]). The approved Sun Valley Substation will be located in the northwest portion of the Town of Buckeye and the existing Morgan Substation is located in the City of Peoria. Generally the transmission line would head north-northeast out of the Sun Valley Substation to north of State Route (SR) 74 and then east to the Morgan Substation.

The Project would require a new right-of-way (ROW) or easement on federal, state, and private lands. The construction ROW would be approximately 200 feet wide, but could be somewhat wider where terrain poses engineering or construction constraints. The permanent and operational ROW width is proposed to be 200 feet wide and would cross approximately seven miles of public lands, north and south of SR 74 in the northeastern part of the Project Area and approximately two miles of public lands in the southwestern portion of the Project Area near the Sun Valley Substation location.

Conditions of Approval

Applicant-committed environmental protection measures are actions, practices, or design features that are part of the Selected Alternative and will be implemented by APS. Under the Selected Alternative, APS will implement the applicant-committed environmental protection measures and BMPs (outlined in detail in Section 2.9, of the final EIS) to minimize adverse impacts of the Project to sensitive environmental resources. These measures include actions and design features related to air quality, cultural resources, geology and minerals, hazardous materials and hazardous and solid waste; public health and safety; paleontology; recreation and special designations; socioeconomics and environmental justice; soils; transportation and traffic; vegetation resources, including saguaro cactus, noxious and invasive weeds, and special status plants; visual resources; and wildlife resources including special status wildlife and migratory birds. These are conditions of approval for the ROW authorization by the BLM, and they are binding in the event that the facility should be transferred or operated by another entity.

There are a number of management prescriptions and other considerations for the Selected Alternative. They are included for one or more of the following reasons: 1) they are already required by law or regulation, 2) they are BMPs or management techniques that could be readily applied to reduce impacts regardless of alternative, 3) they were developed to address issues specific to the Project Area and could be readily applied to reduce impacts, 4) they pertain to actions and/or plans already occurring and/or over which the BLM has no jurisdiction, and 5) they pertain to BLM decisions related to the Project Area that are independent of decisions with respect to the Selected Alternative (i.e., BLM decisions regarding the Selected Alternative would not necessitate changes to decisions related to these items and vice versa).

A Plan of Development (POD) is required before the BLM decides to issue a ROW grant pursuant to BLM Instruction Manual (IM) No. 2011-060 (Feb. 7, 2011) and 43 CFR § 2804.25(b). The BLM ROW policy requires that the installation of the transmission line be consistent with the approved POD. If there were to be any unanticipated changes to the POD, the BLM would assess the potential effects of the post-final EIS alterations to the POD by preparing a determination of NEPA adequacy. APS has prepared and submitted a sufficient POD to the BLM that addresses pertinent aspects of Project development, including but not limited to transmission line and access road construction and maintenance; vegetation removal; natural, cultural, and biological resources mitigation and monitoring; and site reclamation. The final POD will incorporate, as applicable, a variety of site-specific plans. A final POD is required, and will be attached to any Notices to Proceed (NTPs) to construct.

Under the Selected Alternative, APS must comply with all applicable laws, ordinances, regulations, and standards (LORS), and must obtain and meet the requirements of all needed permits.

The Selected Alternative establishes a 200-foot-wide single-use utility corridor on BLM-managed public land north of SR 74 that directly corresponds to the 200-foot-wide ROW for the Project. The nature of this corridor designation limits development on BLM-managed public lands north of SR 74 to the Project; any future requested ROWs for additional development would require consideration of amending the RMP, as the corridor designated by the Selected Alternative is exclusive only to the Project.

The Selected Alternative also establishes a multiuse utility corridor on BLM-managed public land south of SR 74. As described in Section 4.1.3 of the final EIS, future development of linear utilities within the multiuse utility corridor would require site-specific analyses of the impacts to resources within the corridor prior to authorization of such utilities.
