SECTION 1.0
EXECUTIVE SUMMARY

1.1 SITE LOCATION

The Catalina Renewable Energy Project property (subject property, or project property) is located in
an unincorporated portion of Kern County, California, approximately 9 miles northwest of the City
of Rosamond, California, and approximately 12 miles southeast of the City of Tehachapi, California
(Figure 1.1-1, Regional Vicinity Map). State Route (SR) 58 (Blue Star Memorial Highway) is located
approximately 11 miles to the north of the subject property, SR 14 (Antelope Valley Freeway) is
approximately 11 miles to the east, and SR 138 (West Avenue D) is approximately 6 miles to the
south (Figure 1.1-2, Project Location Map). The subject property is primarily located to the south
and west of the intersection of Backus Road and Tehachapi–Willow Springs Road.

The proposed project property is an irregular-shaped site encompassing approximately 7,472 acres.
The subject property is depicted on the U.S. Geological Survey (USGS) 7.5-minute series
Tylerhorse Canyon,1 and Willow Springs,2 topographic quadrangles (Figure 1.1-3, Topographic
Map with USGS 7.5-Minute Map Index). The proposed project is located within Township 10
North, Range 14 West, Sections 9, 14, 15, 16, 20, 21, 22, 23, 26, 27, 28, 29, 30, 31, 32, 34, and
35, and Township 10 North, Range 15 West, Section 25.

The subject property ranges in elevation from 3,000 feet to 3,880 feet above mean sea level at the
southeastern-most and northwestern-most corners of the proposed project boundary, respectively
(Figure 1.4-3).

1.2 SITE SURVEY INSPECTION DATES

The subject property was reviewed on two separate occasions. As a part of the Avalon Renewable
Energy Project, the property was inspected on April 23 and 24, 2009. The Catalina Renewable
Energy Project resulted from reconfiguration of the Avalon Renewable Energy Project area, and
newly acquired parcels were inspected on December 8, 2010.

1.3 INDIVIDUALS PERFORMING THE PHASE I ENVIRONMENTAL SITE ASSESSMENT

Ms. Madeline B. Worsnopp, hazardous materials coordinator, and Dr. M. Anthony Collins, senior
hazardous materials specialist, performed the Phase I Environmental Site Assessment of the subject
property associated with the April 2009 inspection. Mr. Andre Anderson, REA, CEC, CES, senior
environmental compliance specialist; Ms. Donna Grotzinger, senior environmental compliance
coordinator; and Ms. Leanna Guillermo, environmental compliance analyst, performed the Phase I
Environmental Site Assessment of the subject property associated with the December 2010
inspection.
