DNR Seeks Comment on 2015 Ozone State Implementation Plan

October 4, 2018

The Iowa Department of Natural Resources (DNR) sent an email requesting public comment on Iowa’s state implementation plan (SIP) for the national ambient air quality standards (NAAQS) for ozone. Federal law requires states to adopt and submit a plan to the EPA for implementation and enforcement within three years.

During the last revision, the ozone standard was lowered from 0.075 parts per million (ppm) to 0.070 ppm per eight-hour average concentration. An electronic copy of the 2015 ozone infrastructure SIP may be here. A public hearing will be held on October 19, 2018, at 1 p.m. in conference room 2E at the Wallace State Office Building, 502 E 9th Street, Des Moines, IA 50319-0034. All comments must be received no later than October 19, 2018.

The DNR will also prepare a responsiveness summary that will include any written or oral comments received during the public participation process and the Iowa DNR’s response to the comments. The completed responsiveness summary will be forwarded to the EPA and made available to the public upon request. If you have comments you would like to share with ABI, or would like ABI to comment on this SIP, please contact Brad Hartkopf.
