HB 1273 -- Night Sky Protection Act Sponsor: Holsman This bill establishes the Night Sky Protection Act to reduce the amount of light emitted into the night sky to near natural levels for specified Missouri protected places including certain parks and historic sights that allow camping, wilderness areas, riverways, and designated military training areas. The Air Conservation Commission within the Department of Natural Resources must develop voluntary guidelines to achieve specified reduction rates starting in 2025. The definition of "air contaminant" is revised to include light and allows the commission to regulate it in the same way as other air contaminants under Chapter 643, RSMo. The commission must determine the natural nighttime sky luminance for each protected place based on environmental conditions; develop a forecast of the luminance over the next year, five years, and 10 years; and annually report to the department the luminance in microcandela per square meter.Copyright (c) Missouri House of Representatives
