Methyl Formate and Propylene Carbonate Added to SCAQMD's Exempt List

摘要

The U.S. Environmental Protection Agency (EPA) lists chemical compounds that are excluded from the federal Volatile Organic Compounds (VOCs) definition. The determination is based on a comparison of the reactivity of ethane, with compounds having greater reactivity being considered VOCs and those having less reactivity being considered "exempt." The EPA's policy has been to exclude organic compounds that have a negligible reactivity level from the regulatory definition of VOCs (which guides states in establishing priorities and focuses emission control efforts on VOCs that significantly increase ozone concentrations).
