EPA moves to implement 8-hour ozone standard

On September 22, 2011, the Environmental Protection Agency (EPA) announced plans to move forward on implementing the 2008 ozone national ambient air quality standard (NAAQS). EPA’s memorandum on its implementation plan is available on the National Association of Clean Air Agencies (NAACA) website: http://www.4cleanair.org/Documents/ImplementationoftheOzoneNAAQS92211.pdf

The 2008 standard was set at 0.075 parts per million (75 parts per billion). Based on monitored data for the 2008-2010 ozone seasons, Wisconsin DNR expects that Sheboygan County will be designated as “marginal” under the 2008 standard. Other counties could potentially be designated as nonattainment based on more current data or due to their transport contribution. EPA notes that, “The actual nonattainment areas will be determined through the designation process, which will include extensive input and review by the states and an opportunity for public comment.”

In its memo, EPA also commits to continuing to move forward with implementation and development of federal rules, such as the Cross State Air Pollution Rule (see article below), the Portland Cement Rule, Light- and Heavy-Duty Vehicle Standards, Maximum Achievable Control Technology Standards for Boilers, the Mercury and Air Toxics Standards, New Source Performance Standards for Commercial Incinerators/Solid Waste Incinerators and the Oil/Gas Sector, and Tier 3 vehicle and fuel standards.

EPA’s Cross State Air Pollution Rule and Wisconsin

By Christopher Tall, Bureau of Air Management

On July 6, 2011, the U.S. Environmental Protection Agency (EPA) finalized the Cross-State Air Pollution Rule (CSAPR), effective January 1, 2012, to replace the Clean Air Interstate Rule (CAIR). This rule requires 27 states, including Wisconsin, to significantly improve air quality by reducing power plant emissions that cross state lines and contribute to nonattainment or maintenance concerns for ozone (O3) or particle pollution (PM2.5) standards.

EPA determined that 12 states contribute to nonattainment or maintenance concerns of the 2006 24-hour PM2.5 standard in Wisconsin. These states include Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Missouri, Nebraska, Ohio, Pennsylvania and West Virginia. Conversely, Wisconsin contributes to nonattainment or maintenance concerns of the 1997 eight-hour ozone standard in Michigan and to nonattainment or maintenance concerns of the 1997 annual PM2.5 standard in Illinois, Indiana, Michigan and Ohio. Wisconsin also contributes to nonattainment or maintenance concerns of the 2006 24-hour PM2.5 standard in Illinois, Indiana and Michigan.

The rule sets emissions budgets, or caps, for two pollutants; utilities are provided emission allocations and must hold allocations for each ton of sulfur dioxide (SO2) or nitrogen oxides (NOx) emissions. EPA has provided default allocations, but states can provide different allocations through a State Implementation Plan (SIP). The Cross-State Air Pollution Rule allows for trading of emissions between utilities within the state and limited out of state trading.

To speed implementation, EPA is adopting federal implementation plans (FIPs) for each of the states covered by this rule. EPA encourages states to replace these FIPs with SIPs starting as early as 2013. The Department will work with Wisconsin utilities to ensure efficient and effective implementation of the Cross-State Air Pollution Rule under a FIP or SIP, which is still to be determined.
