EPA is promulgating significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 119 chemical substances which were the subject of premanufacture notices (PMNs). Four of these chemical substances are subject to TSCA consent orders issued by EPA. This action requires persons who intend to manufacture, import, or process any of these 119 chemical substances for an activity that is designated as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification will provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.

This final rule is being issued as required by a consent decree governing the schedule for completion of this review of the air quality criteria and the secondary national ambient air quality standards (NAAQS) for oxides of nitrogen and oxides of sulfur. Based on its review, the EPA is retaining the current nitrogen dioxide (NO<INF>2</INF>) and sulfur dioxide (SO<INF>2</INF>) secondary standards to address the direct effects on vegetation of exposure to gaseous oxides of nitrogen and sulfur and, for reasons described in detail in this final preamble, is not adding new standards at this time to address effects associated with the deposition of oxides of nitrogen and sulfur on sensitive aquatic and terrestrial ecosystems. In addition, in this rule the EPA describes...
