Abstract
EPA is making final determinations that the Hayden, Nogales, and Paul Spur/Douglas nonattainment areas in Arizona attained the National Ambient Air Quality Standard (NAAQS) for particulate matter with an aerodynamic diameter of less than or equal to a nominal ten micrometers (PM<INF>10</INF>) by their applicable attainment dates of December 31, 1994. On the basis of these determinations, EPA concludes that these three "moderate" nonattainment areas are not subject to reclassification by operation of law to "serious." EPA is not finalizing determinations with respect to the air quality in these areas subsequent to their 1994 attainment dates.
