EPA Proposes More Stringent Ozone Standard of 65-70 Parts Per Billion

The Environmental Protection Agency proposed a more stringent national ozone standard, between 65 and 70 parts per billion, on November 26, saying the level is necessary to protect human health under the Clean Air Act. With an estimated cost to the economy of $3.4 trillion, manufacturing leaders in Washington are calling it the most expensive regulation ever.  For more information, please see the proposed rule and fact sheet.

EPA’s Proposed Significant New Use Rule (SNUR) for Nonylphenols (NP) and Nonylphenol Ethoxylates (NPE)

UPDATE: Comment Deadline Extended to January 15, 2015.

On October 1, 2014, EPA proposed a significant new use rule (SNUR) for 15 nonylphenol (NP) and nonylphenol ethoxylate (NPE) substances. 79 Fed. Reg. 59186. For 13 of these substances, EPA is proposing that any use is a significant new use (see Table 1 below), and for two of the substances EPA is proposing that any use other than a use as an intermediate or use as an epoxy cure catalyst is a significant new use (see Table 2 below). If a use is designated a significant new use, then persons subject to the SNUR would have to submit a pre-manufacture notice to EPA at least 90 days prior to manufacturing, importing or processing the chemical substances. The notification would allow EPA to evaluate the use and prevent any risks from potential exposures before any commercial activity with the chemical occurs.

NPs are used as intermediates to produce NPEs, and NPEs are used in a wide variety of applications, including some surface finishing applications. The proposed SNUR would apply to those uses that are not ongoing as of October 1, 2014. NASF supplier members should identify any uses of NPs and NPEs in the surface finishing industry so that these uses are not designated as significant new uses and subject to the pre-manufacture notification requirements. Please provide The Policy Group with any information regarding use of NPs and NPEs so that we can identify them for EPA in comments. Comments on the proposed SNUR must be submitted by January 15, 2015. For more information on the proposed SNUR, please contact Jeff Hannapel at jhannapel@thepolicygroup.com.
