(a) If a new underground gas storage facility is proposed, the commission shall ensure that a risk assessment evaluating the potential impact of a leak from the facility on public and environmental health, safety, and welfare is conducted by the project proponent. Both acute and chronic exposures from a range of expected emissions and emission rates shall be evaluated. The evaluation shall include consideration of population density in proximal communities, environmentally sensitive areas, emergency response times, evacuation times, possible leak duration, possible chemical species emitted, and local meteorology. (b) In evaluating the potential risks and impacts of acute and chronic exposures from emissions from a proposed new gas storage facility, the project proponent shall assess or cause to be assessed risks associated with the proposed facility’s proximity to any living quarters, including private homes, condominiums, apartments, retirement homes, prisons, dormitories, or other housing; education resources, including preschools and schools operating kindergarten or any of grades 1 to 12, inclusive; day care centers; and health care facilities, including hospitals, nursing homes, and long-term care and hospice facilities. Based on the risk analysis, appropriate setbacks to the listed structure types shall be determined by the commission. (c) The risk assessment conducted pursuant to this section shall be subjected to peer review by independent experts whose demonstrated expertise includes, but is not limited to, the fields of public health, epidemiology, and toxicology. (d) The findings of any risk assessment required by this section shall be reported pursuant to Section 911.2.
