Notes: ICR Codes for NSPS:D = units constructed after 8/17/1971 and before 9/18/1978. 1 - All Plants: Present Max heat input (MMBtu/hr) is based on approximate maximum historical hourly rate. Da(1) = units constructed after 9/18/1978 and before 2/28/2005. 2 - For Martin Lake Boiler 2, the present operating gross efficiency was not available and was assumed to be the same as the identical Boiler 1. Da(2) = units constructed after February 28, 2005. 3 - Oak Grove Boiler 2 was not operational as of Jan. 4, 2010 when the ICR was received. Accordingly, no data is available for actual boiler operation. N = No NSPS 4 - MWe Gross and Net capacity are based on 50% of MWe coming each from Boilers 5A and 5B, which power the single generator (Unit 5). 5 - Hours per year operation and annual capacity factor for Oak Grove Boiler 1 and Sandow Station Boilers 5A and 5B are based only on 2009, starting with the dates these boilers began commercial operation.
