Abstract
The Environmental Protection Agency (EPA) is approving a revision to the Illinois state implementation plan (SIP) to amend requirements applicable to certain coal-fired electric generating units (EGUs). These amendments require the Will County 3 and Joliet 6, 7, and 8 EGUs to permanently cease combusting coal; allow other subject EGUs to cease combusting coal as an alternative means of compliance with mercury emission standards; allows the transfer of an existing sulfur dioxide (SO<INF>2</INF>) control technology requirement exemption from Joliet 6 EGU to Will County 4 EGU; require all subject EGUs to comply with a group annual nitrogen oxide (NO<INF>X</INF>) emission rate; and require only those subject EGUs that combust coal to comply with a group annual SO<INF>2</INF> emission rate. EPA proposed this action on August 31, 2017, and received two public comments in response.
