The Environmental Protection Agency published a notice December 21 withdrawing significant new use rules (SNURs) for eight chemicals due to objections it received. The eight SNURs were among 20 the agency published as direct final rules November 2, and it intends to reissue them as proposed rules for comment in a future notice, but it has not given a timeline for publishing them. Six of the eight withdrawn chemicals are complex mixtures containing benzene and are made by a renewable fuels company that has designed drop-in fuels to replace traditional fossil fuels.
