a) Under the CAA these nonattainment areas are further classified as
subpart 1 or subpart 2 (subpart 2 is further classified as marginal,
moderate, serious, severe or extreme) based on their design values.  An
Early Action Compact (EAC) area is one that has entered into a compact
with the EPA and have agreed to reduce ground level ozone pollution
earlier than the CAA would require in exchange the EPA will defer the
effective date of the nonattainment designation.  The severe designation
is denoted as severe-15 or severe-17 based on the maximum attainment
date associated with the classification.

b) Boston-Manchester-Portsmouth (SE), NH has the same classification as
Boston-Lawrence- Worcester (E. MA), MA.
