## Abstract

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Maine. This revision establishes and requires general permit regulations for nonmetallic mineral processing plants and concrete batch plants. The regulations provide an option for minor new sources of air emissions to comply with the State's minor new source review (NSR) rules in lieu of obtaining an individual permit. The intended effect of this action is to approve Maine's general permit regulations for minor source nonmetallic mineral processing plants and concrete batch plants. This action is being taken in accordance with section 110 the Clean Air Act.
