Approval and Promulgation of Implementation Plans and Designation

of Areas for Air Quality Planning Purposes: State of Michigan

Correction

In proposed rule document 94-17556 beginning on page 37190 in the

issue of Thursday, July 21, 1994 make the following corrections:

1. On page 37198, in the first column, the first two full

paragraphs should be removed and in the second column, the first ten

lines should be removed beginning with ``factors'' and ending with

``TSD.''

2. On page 37199, in the first column, in the first line, after

``period.'' insert missing text as set forth below:

``6, 1994 Stage II is no longer a requirement (section 202 (a)(6)

of the Act). However, if the State chooses to include this program as a

contingency measure, enabling legislation would suffice. Michigan has

chosen to retain Stage II as a contingency measure in the maintenance

plan. Finally, the State submitted to USEPA a section 182 (f) NOx

exemption petition based on 1991-1993 ambient air quality data that

demonstrates that the area is attaining the ozone NAAQS. The USEPA is

currently taking action on this submittal. Since the Detroit-Ann Arbor

area has demonstrated that it can maintain the standard without the

implementation of these programs, USEPA proposes that the maintenance

plan be approved with these elements as contingency measures. In

addition, based on the maintenance demonstration, the USEPA plans to

propose approval of the basic I/M enabling legislation (based on the

June 28, 1994 proposed I/M Redesignation Rule), and the Stage I rule

and 182 (f) NOx exemption petition in a separate FR action.

C. Verification of Continued Attainment

Continued attainment of the ozone NAAQS in the Detroit-Ann Arbor

area depends, in part, on the State's efforts toward tracking

indicators of continued attainment during the maintenance''
