Regional Haze Plan Available for Public Comment
The DNR invites the public to provide comment on a proposed revision to Iowa’s state implementation plan (SIP) to address the second 10-year planning period (2019-2028) of the federal regional haze rule. This comment opportunity also includes two proposed air construction permitting actions that establish plan requirements for new emissions reductions. The draft regional haze plan further provides a 5-year progress report to close out the first 10-year planning period (2009-2018).
As part of the proposed SIP revision, the DNR is proposing to require operational improvements to existing control equipment at MidAmerican Energy Company’s Louisa Generating Station (LGS) and Walter Scott Jr. Energy Center – Unit 3 (WSEC-3). The improvements would permanently reduce the combined SO2 emissions from these sources by approximately 9,700 tons per year. Implementation would begin later this year, as specified in draft permits 05-A-031-P6 and 75-A-357-P9 for LGS and WSEC-3, respectively.
The draft plan and its appendices are accessible through the links below. All files are PDF, except Appendices C-1 and C-2, which are relatively large Microsoft Excel files. Appendix E contains the draft permits for LGS and WSEC-3.
