On October 1, 2014, the U.S. Environmental Protection Agency (EPA) proposed a significant new use rule (SNUR) for 15 related chemical substances commonly known as nonylphenols (NP) and nonylphenol ethoxylates (NPE). These substances are recognized as persistent and toxic in the environment. This article discusses this important move.
The EPA proposes to designate any use of the 13 NPs and NPEs listed in Table 1 as a significant new use, and any use other than as an intermediate or an epoxy cure catalyst as a significant new use of the two additional NPs listed in Table 2.
