California Air Resources Board

Requires CARB to develop a response framework that establishes best practices and guidance for addressing fugitive and natural sources of hydrogen sulfide (H2S) gas and for community preparation and response to H2S exposure events. The bill requires the response framework to consider cross-media releases, develop integrated, multi-agency approaches to identify and address fugitive and natural sources, develop methods for reducing identified fugitive and natural sources of H2S gas in impacted communities, and consider acute and chronic reference exposure levels as well as the influence of varying climates and settings on exposure, among other things. The bill requires the Office of Environmental Health Hazard Assessment to update the acute and chronic reference exposure levels for H2S and to develop additional health guidance values for H2S, if the need is identified by CARB.
