Source-supplied abstracts

Existing law generally designates the State Air Resources Board as the state agency with the primary responsibility for the control of vehicular air pollution, and designates air pollution control districts and air quality management districts with the primary responsibility for the control of air pollution from all sources other than vehicular sources. Existing law requires the state board to inventory sources of air pollution within the air basins of the state, determine the kinds and quantity of air pollutants, and monitor air pollutants in cooperation with districts and other agencies. Existing law requires the state board to adopt standards of ambient air quality for each air basin in consideration of the public health, safety, and welfare, including, but not limited to, health, illness, irritation to the senses, aesthetic value, interference with visibility, and effects on the economy. Existing law authorizes these standards to vary from one air basin to another. This bill would require the state board, in consultation with specified entities, to develop, as provided, a response framework that establishes best practices and guidance for addressing fugitive and natural sources of hydrogen sulfide gas and for community preparation and response to hydrogen sulfide exposure events originating from these sources. The bill would require the state board, in developing the response framework, to conduct at least 3 public workshops, including at least one located in the Tijuana River Valley region, at least one located in the Salton Sea region, and at least one selected in consultation with a community that has experienced significant hydrogen sulfide exposure. The bill would require the Office of Environmental Health Hazard Assessment to update the acute and chronic reference exposure levels for hydrogen sulfide and to develop additional health guidance values for hydrogen sulfide, if the need is identified by the state board, in consultation with the office, during development of the response framework.
