The tracking number is DOE/EA-2098. W APA determined that a FONS I was appropriate for the Proposed Action based on the analysis in the Final Environment Assessment titled "AZ Solar 1 Interconnection Project: DOE/EA-2098" and dated July 2019.

Thank you for your interest in this project. Sincerely, ~~ Environmental Manager FINDING OF NO SIGNIFICANT IMPACT AZ Solar 1 Interconnection Project, La Paz County, Arizona DOE/EA-2098 AGENCY: U.S. Department of Energy, Western Area Power Administration ACTION: Finding of No Significant Impact BACKGROUND: U.S. Department of Energy (DOE), Western Area Power Administration (WAPA) proposes to approve AZ Solar 1 LLC's application to interconnect its proposed facility to the Little Harquahala to Harcuvar 115-kilovolt transmission line and enter into an interconnection agreement. W APA operates and maintains this transmission line, which is part of the Central Arizona Project, on behalf of the Bureau of Reclamation (Reclamation). Bureau of Land Management (BLM) previously issued a right-of-way (ROW) to Reclamation for this transmission line. The interconnection agreement's purpose is to ensure that the request will not degrade existing transmission reliability and service. Section 211 of the Federal Power Act requires that transmission service be provided upon request if capacity is available. In association with the interconnection agreement, W APA would: 1) Install and maintain a tap consisting of up to two new pole structures located in the existing transmission line ROW and associated overhead conductors; 2) Add guy wires and anchors at up to three existing pole structures; 3) Seek approval from Reclamation for the proposed changes to the transmission line; 4) Upgrade relays in existing control buildings at Harquahala and Harcuvar substations; and 5) Install a microwave dish at W AP A's existing Pete Smith Peak microwave site. The proposed interconnection tap would be located on BLM land in the east half of Section 13 in Township 5 North, Range 14 West on the Gila and Salt River Baseline and Meridian (GSRBM). BLM plans to respond to AZ Solar l LLC's application for an up to 100-foot-long ROW for an overhead transmission line connection from WAPA's proposed tap to the proposed solar energy facility. BLM would seek concurrence from Reclamation about any encroachments on the existing transmission line ROW. AZ Solar l LLC plans to build, operate, and maintain a 32.5-megawatt photovoltaic solar energy generation facility on a 480-acre parcel of private land. An optional 27.5 megawatts of photovoltaic solar energy generation, 20 megawatts of battery storage, or both may be added within the parcel based on market considerations. AZ Solar 1 LLC would operate the entire facility such that the annual output is equal to or less than 50 average megawatts. AZ Solar 1 LLC would: 1) Install photovoltaic solar panels; 2) Install underground collection lines from each panel to a collection point switchyard; 3) Create access roads within the facility for construction and maintenance; 4) Build an on-site collection point switchyard covering five acres; and 5) Install an overhead transmission line, up to l 00 feet long, between the solar energy facility and W AP A's tap, as well as apply to BLM for the associated ROW. 2 The facility would be located on private land approximately two miles west of Salome situated within portions of Section 18 in Township 5 North, Range 13 West on the GSRBM. W APA prepared a Final Environmental Assessment (FEA) analyzing the Proposed Action and a No Action Alternative. It is titled "Final Environmental Assessment AZ Solar l Interconnection Project: DOE/EA-2098" and dated July 2019. WAPA is the lead Federal agency, and BLM (Lake Havasu Field Office) and Reclamation are cooperating agencies. WAPA incorporates this EA by reference. On March 19, 2019, WAPA determined that the Proposed Action would not affect any species listed under the Endangered Species Act, because suitable habitat is not present in the project area. W APA consulted with the Arizona State Historic Preservation Officer (SHPO) and consulting parties under Section 106 of the National Historic Preservation Act. On March 25, 2019, the SHPO concurred with WAPA's finding of no historic properties affected (SHP0-2018-1892(147705)). DETERMINATION: Based on the analysis contained in DOE/EA-2098, WAPA finds that the Proposed Action to approve AZ Solar 1 LLC's application and enter into an interconnection agreement does not constitute a major Federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA). Therefore, preparation of an environmental impact statement is not required, and WAPA issues this Finding of No Significant Impact (FONSI).

The SEZ has a 15 total area of 3,878 acres (16 km2). In 2008, the county population was 20,005, while adjacent 16 Riverside County to the west in California had a population of 2,087,917. The towns of 17 Quartzsite and Salome in La Paz County are about 18 mi (29 km) west of, and 18 mi (29 km) 18 east of, the SEZ respectively. The Phoenix metropolitan area is approximately 100 mi (161 km) 19 to the east of the SEZ, and Los Angeles is approximately 230 mi (370 km) to the west. 20 21 The nearest major road access to the SEZ is via U.S. 60, which runs southwest to 22 northeast, along the southeast border of the Brenda SEZ. The nearest railroad stop is 11 mi 23 (18 km) away. The nearest airports serving the area are the Blythe and Parker (Avi Suquilla) 24 Airports, both approximately 50 mi (80 km) from the SEZ, and neither of which have scheduled 25 commercial passenger service. The Sky Harbor Airport in Phoenix is 125 mi (201 km) to the 26 east, and Yuma International Airport in Yuma is 104 mi (167 km) to the south, of the SEZ.

  • Geochronology, Geology, and Listric Normal Faulting of the Vulture Mountains, Maricopa County, Arizona
    Arizona Geological Society Digest, Volume XII, 1980 89 Geochronology, Geology, and Listric Normal Faulting of the Vulture Mountains, Maricopa County, Arizona by WA. Rehrigi, M. Shafiqullah2, and P.E. Damon2 Abstract Geologic mapping and geochronologic studies in the Vulture Mountains near Wickenburg, Arizona, have led to the recognition of a large, northeast-trending batholith of 68.4-m.y. age that intrudes complex gneissic and granitic rocks of probably Precambrian age. Over- lying the denuded crystalline terrane is a sequence of late Oligocene to Miocene ( .'26 to 16 m.y.) volcanic rocks (vitrophyres, ash-flow tuffs, welded tuffs, breccias, agglomerates, and lava flows) that vary locally. Nearby source areas are suggested. A swarm of north- to north-northwest-trending porphyritic dikes intrudes the volcanics and crystalline basement. Overlying this volcanic sequence in angular unconformity is a thin section of basal conglom- erate and basalt lava flows dated at 13.5 m.y. B.P. The older, tuffaceous sequence is generally calc-alkalic but with a high proportion of rhyolites that are exceptionally rich in potassium and silica. These silicic units are peral- kaline or nearly so, and those with K20/Na2O >3 are ultrapotassic. Initial strontium ratios average 0.7081, whereas an initial ratio for the younger basalt sequence is significantly lower at 0.7054. The silicic volcanics have been severely tilted on multiple, low-angle listric normal faults. The youngest basalt flows are relatively flat lying and postdate this deformation. By geo- logic and radiometric criteria, the transition from tilted silicic volcanics to untilted basalts occurred between about 16 and 14 m.y.
