Illinois (Part 63) MACT Standards Delegations

Clean Air Act Section 112 Major and Area Source Standards

EPA's final delegation approval of Section 112 NESHAP standards for Illinois constitutes a program of straight delegation of all existing and future air toxic standards regardless of a source's Part 70 (Title V) applicability. Straight Delegation will operate as follows: upon promulgation of a Section 112 standard (includes major and area sources), the State of Illinois automatically receives the authority and assumes the responsibility for the timely implementation and enforcement required by the standard, as well as any further activities agreed to by IEPA and EPA.

The Illinois Database will be made available as a spreadsheet.
