CALIFORNIA LEGISLATURE 20172018 REGULAR SESSION Assembly Bill No. 2120Introduced by Assembly Member QuirkFebruary 08, 2018 An act to amend Section 41856 to the Health and Safety Code, relating to emissions. LEGISLATIVE COUNSEL'S DIGESTAB 2120, as introduced, Quirk. Fire: agricultural burning.Existing law requires the State Air Resources Board to promulgate guidelines for the regulation and control of agricultural burning for each of the air basins established by the state board.This bill would require the regulations to include a technical discussion of the likely emissions trade-offs of planned prescribed fire or managed wildfire ignitions, as provided.Digest Key Vote: MAJORITY Appropriation: NO Fiscal Committee: YES Local Program: NO Bill TextThe people of the State of California do enact as follows:SECTION 1. Section 41856 of the Health and Safety Code is amended to read:41856. (a) The state board shall promulgate guidelines for the regulation and control of agricultural burning for each of the air basins established by the state board.(b) The burn authorization regulations shall include a technical discussion of the likely emissions trade-offs of planned prescribed fire or managed wildfire ignitions according to both of the following:(1) A discussion of likely emission outputs, either modeled, monitored real-time emissions, or remotely sensed plume densities from similar conditions. These outputs shall be compared to unplanned wildfire emissions at 97th percentile weather to display emission trade-offs and cumulative effects of planned and unplanned fire events. The use of best available scientific methodologies will build better understanding between the public, policy makers, air regulators, and fire managers while managing Californias natural resources.(2) A discussion of science-based fire regimes and fire frequency and the level of fire return interval departure for permitted burning in all the vegetation types where that information is available in the state.
