R 336.2508 Eligibility provisions and prohibitions for mercury program.

Rule 1508. (1) For mercury emissions to be eligible for source-wide averaging or source- wide pooling in a 12-month rolling average basis or time period as determined at the end of each calendar month, the emissions must be generated in the same month. (2) If source-wide averaging or source-wide pooling is used under R 336.2503(4)(b) in the compliance demonstration plan, the effect of a failure to demonstrate compliance with the cumulative mercury emission limit will be that the compliance status of each EGU must be determined on an individual basis, as if no averaging or pooling plan existed. (3) Mercury emissions from an affected EGU, under R 336.2503(4), may only be averaged or pooled within a single compliance demonstration plan per 12-month rolling average basis or time period as determined at the end of each calendar month. (4) Mercury emission limits received as part of an approved multi-pollutant compliance demonstration project, an extension demonstration, and for new EGUs shall not be available for the averaging or pooling methods allowed under R 336.2503(4)(b). (5) For the Lansing Board of Water and Light, Eckert Power Station affected existing EGUs, the result of a failure to demonstrate compliance with the cumulative mercury emission limit will be that the compliance status of each EGU must be determined on an individual basis, as if no stationary source-wide pooling plan existed under R 336.2504(2)(d).
