## Abstract

We are converting our limited approval under the Clean Air Act of the Commonwealth of Massachusetts State Implementation Plan (SIP) revision for an enhanced vehicle inspection and maintenance program to a full approval. In our limited approval, we said Massachusetts needed to submit revisions to its SIP to address four sections of EPA's enhanced I/M regulation for full approval. We have determined that on October 20, 2000 Massachusetts submitted revisions that meet all of the conditions for full approval. Additionally, we are also approving an interim level of emission reduction credit for the inspection and maintenance program that can be utilized by Massachusetts in attainment planning. The intent of this action is to convert our limited approval of Massachusetts' enhanced vehicle I/M program SIP to a full approval and to approve an interim level of emission reduction credit for attainment planning purposes.
