On August 24, 2017, the Environmental Protection Agency (EPA) published a notice of proposed rulemaking to approve the Iowa State Implementation Plan (SIP) revision for attaining the 1-hour sulfur dioxide (SO<INF>2</INF>) primary National Ambient Air Quality Standard (NAAQS) for the Muscatine nonattainment area (herein called a "nonattainment plan") in the Federal Register. EPA received several comments, including one suggesting that insufficient information was provided in the docket to allow the reviewer the ability to fully evaluate the nonattainment plan and EPA's proposed action to approve it and another comment that insufficient emissions inventory information for the 2018 attainment year was provided for the action. As a result, we are: Providing additional information in the docket and clarifying that all information, including files that are too large to be provided in the docket, are available upon request; providing an updated 2018 projected emissions inventory; and reopening the public comment period to afford stakeholders an opportunity to comment on these specific additions of information only. EPA has updated Document A, "Index of Docket Documents" in the docket to this rulemaking. EPA will address all comments received on the original proposal and on this supplemental action in our final action.
The agency’s own summary, as published.
