nSet federal standards designed to enhance the quality of
the air by deterring air polluters.
nIn 1977, Congress passed a series of amendments establishing stricter standards for air quality. As amended, the act provides criminal sanctions for violation of any provisions for which civil penalties
apply, and for any person who
knowingly makes any false representation
in a document filed under the act.
nEnforcement may be delegated to the states pursuant to the State Implementation Plan (SIP), but the states are not required to enact minimum criminal provisions to receive EPA approval of their implementation plans.
