## Abstract

EPA is promulgating amendments to the new source performance standards for coal preparation and processing plants. These final amendments include revisions to the emission limits for particulate matter and opacity standards for thermal dryers, pneumatic coal cleaning equipment, and coal handling equipment (coal processing and conveying equipment, coal storage systems, and coal transfer and loading systems) located at coal preparation and processing plants. These revised limits apply to affected facilities that commence construction, modification, or reconstruction after April 28, 2008. The amendments also establish a sulfur dioxide (SO<INF>2</INF>) emission limit and a combined nitrogen oxide (NO<INF>X</INF>) and carbon monoxide (CO) emissions limit for thermal dryers located at coal preparation and processing plants. In addition, the amendments establish work practice standards to control fugitive coal dust emissions from open storage piles located at coal preparation and processing plants. The SO<INF>2</INF> limit, the NO<INF>X</INF>/CO limit, and the work practice standards apply to affected facilities that commence construction, modification, or reconstruction of which commences after May 27, 2009. We are also modifying the definition of thermal dryer to include both direct contact and indirect contact thermal dryers drying all coal ranks. We are modifying the definition of pneumatic coal-cleaning equipment to include equipment cleaning all coal ranks. We are also amending the definition of coal for purposes of subpart Y to include coal refuse. The modified definitions of thermal dryer, pneumatic coal cleaning equipment, and coal will be used to determine whether and how the standards apply to facilities that commence construction, modification, or reconstruction after May 27, 2009.
