Summary

The Environmental Protection Agency (EPA) is proposing to approve State Implementation Plan (SIP) and Operating Permit Program revisions submitted by the State of South Dakota on October 23, 2015, related to South Dakota's Air Pollution Control Program. The October 23, 2015 submittal revises certain definitions in the Prevention of Significant Deterioration (PSD) permitting rules and general definition section related to greenhouse gases (GHGs). In this rulemaking, we are proposing action on portions of the October 23, 2015 submittal, which were not acted on in our previous final rulemaking published on October 13, 2016. The effect of this rulemaking is to ensure that certain definitions in South Dakota's PSD rules are in compliance with the federal PSD requirements. This action is being taken under the Clean Air Act (CAA).
