EPA is proposing to approve 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; exempt the Will County 4 EGU from sulfur dioxide (SO<INF>2</INF>) control technology requirements; 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.
The agency’s own summary, as published.
