California's Senate Bill 1137 (SB 1137) establishes new safety measures to protect public health by creating buffer zones between oil and gas operations and community spaces. This legislation creates a 3,200-foot Health Protection Zone (HPZ) around homes, schools, hospitals, and other sensitive locations where people live, work, and gather.
