Superstition Substation to Bullfrog Dairy Electrical Distribution Line Environmental Assessment (EA)

Client: Imperial Irrigation District

Location: Imperial County, CA

UltraSystems prepared an Environmental Assessment (EA) on behalf of the Imperial Irrigation District for the installation of a new approximately 5,200-linear-foot, electrical distribution line from the Superstition Substation to Bullfrog Diary, located  in Imperial County.  Bullfrog Farms relocated its family-owned dairy, known as Bullfrog Dairy (i.e., with 2000 dairy cows) from Corona, California to Imperial County, California. 

The Dairy is located .65 miles to the south of the existing Superstition Substation. New distribution lines were built from Superstition Substation to the Bullfrog Dairy site.  The line comprised of 397 AAC (4) wires, approximately 5200 ft. long.  This line was insulated at 15,000 volts and energized in Phase 1 at 7.2kV.

The installation of the new distribution line encroached within the California Desert Conservation Area (CDCA), regulated by the California Desert District of the Bureau of Land Management (BLM).  Because installation of the distribution line would affect federal lands under the administration of the BLM, the project was subject to guidelines of the National Environmental Policy Act (NEPA).  As part of the EA, UltraSystems also prepared several technical studies, including: air quality, cultural resources, biological resources and land use compatibility studies.
