§ 52.743 Continuous monitoring.

(a) Alternative monitoring requirements established under Section 201.402 of Title 35, IAC must be either: Incorporated into a federally enforceable operating permit or construction permit or submitted to USEPA for approval as a revision to the Illinois State Implementation Plan (SIP). Illinois shall set forth alternative emissions monitoring and reporting requirements to satisfy the intent of 40 CFR part 51, appendix P whenever Illinois exempts any source subject to Section 201.401 from installing continuous emission monitoring systems. Illinois may exempt a source if the source cannot install a continuous emission monitoring system because of physical plant limitations or extreme economic reasons, according to the criteria of Section 201.402.
