The only development since this paper was written is that the Court has ruled against our Rule 430, as we discussed. An illustration of the nonattainment area and the air monitor which is referenced in the white paper. A letter we received, following the Rule 430 ruling from Region 5. Sierra Club v. EPA 18cv3472 NDCA Tier 10 ED 002061 00176768-00001 We look forward to seeing you next week and to working with you on the important regional and national policy issues which we believe this matter presents. Have a good Thanksgiving. Tim O'Brien Senior Advisor MDEQ Sierra Club v. EPA 18cv3472 NDCA Tier 10 ED 002061 00176768-00002
