Dear Mr. Mathur:

STEVEN E. CHESTER

DIRECTOR

The Michigan Department of Environmental Quality (MDEQ) is submitting a number of

new Michigan Air Pollution Control rules, rule revisions, and a rule rescission as a

revision to Michigan's State Implementation Plan (SIP) and requests your approval of

the revised SIP.

The submittal consists of three separate rules packages including the revised Part 2

New Source Review (NSR) permitting rules and the rescission of the outdated

nonattainment rule, the addition of the Part 19 rules revising Michigan's NSR for Major

sources in nonattainment areas to include the federal NSR reforms, and other revisions

that are affected by the federal NSR rules.

The Michigan Air Pollution Control Rules included in the three rules packages are as

follows:

• Part 1. General Provisions. Revisions include amendments to R 336.1102 to

R 336.1105, R 336.1109, R 336.1112 to R 336.1114, and R 336.1122. These

revisions were made to modify the definitions that impact the new NSR permitting

rules in Part 19 as well as modify the definition of volatile organic compound.

• Part 2. Air Use Approval. Revisions include amendments to R 336.1201,

R 336.1202, R 336.1205, R 336.1207, R 336.1211, R 336.1213, R 336.1214,

R 336.1214a, R 336.1219, R 336.1240, R 336.1241, R 336.1278, R 336.1281,

R 336.1284, R 336.1285, R 336.1288, and R 336.1299. Rule 336.1277 has been

added, and R 336. '1220 has been rescinded and replaced by new NSR and

Prevention of Signification Deterioration permitting rules in Parts 19 and 18,

respectively. In addition, all relevant citations in the Purl 2 rules have been changed

to reflect the state's new permitting authority in the new Part 18 and Part 19 rules.

• Part 19. NSR for Major Sources Impacting Nonattainment Areas. These are new

rules: R 336.2901, R 336.2901a, R 336.2902, R 336.2903, R 336.2907,

R 336.2908, and R 336.2910.

Mr. Bharat Mathur -2- March 24, 2009

We request that these rules, with the exception of R 336.1211, R 336.1213,

R 336.1214, R 336.1214a, R 336.1277, and R 336.2910, be approved as part of the

SIP.

In addition to action on these rules packages, we are requesting that the "reasonable

possibilities" provision in R 336.2818(3)(f), submitted in a rules package on

September 30, 2008, be approved as part of the SIP. This request was originally made

in the September 30 submittal to the EPA, but the EPA is asking that we make the

formal request again.

We appreciate your attention to this matter. If you have any questions regarding this

submittal, please contact Mr. Robert Irvine, AQD, at 517-373-7042.
