Pennsylvania Attainment Date Extension for the Pittsburgh-Beaver Valley Ozone Nonattainment Area; PA and VA Determination of Valid Air Quality Data

EPA is extending the attainment date for the Pittsburgh-Beaver Valley moderate ozone nonattainment area in Pennsylvania from November 15, 1996 to November 15, 1997. This extension is based in part on monitored air quality readings for the national ambient air quality standard (NAAQS) for ozone during 1996. Accordingly, EPA is updating the table in 40 CFR part 81 concerning attainment dates in the Commonwealth of Pennsylvania. EPA is also announcing its determination that air quality data collected during 1996 indicates attainment of the ozone NAAQS in the Reading, Pennsylvania and the Richmond, Virginia moderate ozone nonattainment areas by the November 15, 1996 deadline for moderate areas.
