Approval and Promulgation of Air Quality Implementation Plans; State of Maryland; Enhanced Inspection and Maintenance Program

Özet

We are converting our conditional approval of the State of Maryland's State Implementation Plan (SIP) revision for an enhanced vehicle inspection and maintenance (I/M) program, which was granted on July 31, 1997 (61 FR 40938), to a full approval. In the State of Maryland the I/M program is known as the vehicle emissions inspection program (VEIP). In our July 31, 1997 conditional approval, we imposed fifteen conditions for full approval. We have determined that Maryland has met all of those conditions for full approval. The intent of this action is to convert our conditional approval of Maryland's VEIP SIP to a full approval.
