CALIFORNIA LEGISLATURE 20212022 REGULAR SESSION Senate Bill No. 1314Introduced by Senator LimnFebruary 18, 2022 An act to amend Section 39660.5 of the Health and Safety Code, relating to air resources. LEGISLATIVE COUNSEL'S DIGESTSB 1314, as introduced, Limn. Toxic air contaminants: human exposure.Existing law requires the State Air Resources Board, in evaluating the level of potential human exposure to toxic air contaminants, to assess that exposure in indoor environments, as well as in ambient air conditions. Existing law requires the state board to consult with the State Department of Public Health concerning what potential toxic air contaminants may be found in the indoor environment and on the best methodology for measuring exposure to these contaminants. Existing law also requires the state board, when the state board identifies toxic air pollutants that have been found in any indoor environment, to refer all available data on that exposure and the suspected source of the pollutant to specified state entities.This bill would make nonsubstantives changes to those requirements.Digest Key Vote: MAJORITY Appropriation: NO Fiscal Committee: NO Local Program: NO Bill TextThe people of the State of California do enact as follows:SECTION 1. Section 39660.5 of the Health and Safety Code is amended to read:39660.5. (a) In evaluating the level of potential human exposure to toxic air contaminants, the state board shall assess that exposure in indoor environments environments, as well as in ambient air conditions.(b) The state board shall consult with the State Department of Health Services, Public Health, pursuant to the program on indoor environmental quality established under Chapter 7 (commencing with Section 105400) of Part 5 of Division 103, concerning what potential toxic air contaminants may be found in the indoor environment and on the best methodology for measuring exposure to these contaminants.(c) When the state board identifies toxic air pollutants that have been found in any indoor environment, the state board shall refer all available data on that exposure and the suspected source of the pollutant to the State Department of Health Services, Public Health, the Division of Occupational Safety and Health of the Department of Industrial Relations, the State Energy Resources Conservation and Development Commission, the Department of Housing and Community Development, and the Department of Consumer Affairs.(d) In assessing human exposure to toxic air contaminants in indoor environments pursuant to this section, the state board shall identify the relative contribution to total exposure to the contaminant from indoor concentrations, taking into account both ambient and indoor air environments.
