The Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove a revision to the Wisconsin State Implementation Plan (SIP) for attaining the 2010 primary, health- based 1-hour sulfur dioxide (SO<INF>2</INF>) national ambient air quality standard (NAAQS or "standard") for the Oneida County SO<INF>2</INF> nonattainment area. This SIP revision (hereinafter referred to as Wisconsin's Oneida County SO<INF>2</INF> plan or plan) includes Wisconsin's attainment demonstration and other attainment planning elements required under the Clean Air Act (CAA). EPA is proposing to approve some elements of the Oneida County SO<INF>2</INF> plan and disapprove some elements of the plan, including the attainment demonstration, since it contains facility credit for a stack height that does not meet the regulations for good engineering practice stack height regarding the prohibition of air pollution dispersion techniques.
