Due to an adverse comment, the Environmental Protection Agency (EPA) is withdrawing the direct final rule for Approval of Kansas Air Quality State Implementation Plans; Construction Permits and Approvals Program, published in the Federal Register on September 21, 2017. Kansas's SIP revisions included revisions to Kansas' construction permit rules. Specifically, these revisions implemented the revised National Ambient Air Quality Standard (NAAQS) for fine particulate matter; clarified and refined applicable criteria for sources subject to the construction permitting program; updated the construction permitting program fee structure and schedule; and made minor revisions and corrections.
