EPA is removing all total suspended particulate (TSP) area designations in New Jersey, New York, Puerto Rico and the Virgin Islands because they are no longer relevant. EPA promulgated revised prevention of significant deterioration (PSD) increments for particulate matter so that the PSD increments are now measured in terms of particulate matter with an aerodynamic diameter less than 10 microns (PM<INF>10) instead of TSP. Section 107(d)(4)(B) of the Clean Air Act (Act) authorizes EPA to eliminate all area TSP designations once the PSD increments for PM<INF>10 are promulgated.
