  • Hazards Associated with Seismic Conditions Are Addressed in Section 4.6, Geology, Soils, and Mineral Resources
    4.7 Hazardous Materials and Public Health 4.7 HAZARDOUS MATERIALS AND PUBLIC HEALTH This section contains a description of the environmental and regulatory settings with respect to hazardous materials and public health and safety. Hazards associated with seismic conditions are addressed in Section 4.6, Geology, Soils, and Mineral Resources. Potential flooding and water quality hazards are addressed in Section 4.8, Water Quality and Hydrology. Public health risks associated with air emissions are addressed in Section 4.3, Air Quality. The issues considered in this section include exposure to chemical contaminants and hazardous wastes and the potential for encountering hazardous contaminants on the surface or subsurface during construction and operation of the proposed Projects. Scoping Issues Addressed During the scoping period for the Projects, two public scoping meetings were conducted and written comments were received regarding potential threats to human health and the environment. One letter was received from the Department of Toxic Substances Control (DTSC) and the other letter was from March Air Force Base on behalf of the U.S. Marine Corps Air Station (MCAS) Yuma. The DTSC recommends the following: . Identify whether conditions within the Project sites may pose a threat to human health or the environment. Search standard regulatory databases to identify any existing environmental contamination issues within the project area. Identify the mechanism that would initiate any required investigation and/or remediation for any site within the proposed project area that may be contaminated and the government agency that would provide appropriate regulatory oversight. Include the findings of any investigations conducted at the site, including any Phase I or II Environmental Site Assessment, and a summary of any sampling results in which hazardous materials were found above regulatory standards.

  • Imperial East SEZ Analysis
    1 9 AFFECTED ENVIRONMENT AND IMPACT ASSESSMENT FOR 2 PROPOSED SOLAR ENERGY ZONES IN CALIFORNIA 3 4 5 9.1 IMPERIAL EAST 6 7 8 9.1.1 Background and Summary of Impacts 9 10 11 9.1.1.1 General Information 12 13 The proposed Imperial East solar energy zone (SEZ) has a total area of 5,722 acres 14 (23.2 km2) and is located in Imperial County in southeastern California, near the United States– 15 Mexico border (Figure 9.1.1.1-1). In 2008, the Imperial County population was 180,493, while 16 the two-county region—Imperial County and Yuma County, Arizona—surrounding the SEZ had 17 a total population of 387,798. Calexico (38,344) is located about 15 mi (24 km) to the west along 18 State Route 98, and El Centro (40,083) lies 19 mi (31 km) to the west along Interstate 8 (I-8) in 19 Imperial County. I-8 runs east–west along the northeast edge of the proposed SEZ, while State 20 Route 98, a two-lane highway, passes through the southern edge. San Diego lies 120 mi 21 (194 km) to the west, and Yuma, 29 mi (47 km) to the east via I-8. A branch line of the Union 22 Pacific Railroad (UP) serves Calexico and El Centro. Four small public airports lie within 34 mi 23 (55 km) of the proposed SEZ. 24 25 A 115-kV transmission line intersects the southwest corner of the SEZ, and a 500-kV line 26 is located about 0.4 mi (0.6 km) to the south, running east–west.
