Abstract
In today's action, we are finalizing regulations to include Delaware and New Jersey in the Clean Air Interstate Rule (CAIR) for fine particles (PM<INF>2.5</INF>), based on our assessment that they contribute significantly to a downwind State's nonattainment. In the CAIR, we determined that upwind States that contribute 0.2 [mu]g/ m<SUP>3</SUP> or more to a downwind PM<INF>2.5</INF> nonattainment area are potentially deemed to be contributing significantly to nonattainment in the downwind State. The EPA proposed to augment the analytical approach used in the CAIR by supplementing the air quality step of the contribution analysis. Based on the results of this augmented analytical approach, we proposed that Delaware and New Jersey should be covered by the CAIR for annual sulfur dioxide (SO<INF>2</INF>) and nitrogen oxides (NO<INF>X</INF>) requirements and are finalizing the regulation to include these States in the CAIR for PM<INF>2.5</INF>.
