### 2010 ACE Cogeneration EPA ICR Testing
8/24/2010 Description of the source (including control equipment). Please see the attachments for source or process flow diagram: The ACE Cogeneration Company Plant consists of a 1052 MMBtu/hour, circulating bed, coal-fired boiler designed to produce 910,000 lb/hr of steam at 1525 psig and 1005°F. The unit is equipped with the following pollution control systems:
1.	An ammonia injection system for control of NOx emissions; 2.	Cyclonic mixing of injected ammonia with flue gas to provide for a minimum amount of ammonia slip (emission); 3.	A limestone injection system to limit emissions of SO2; 4.	A baghouse to restrict opacity and emissions of sulfates and particulate;
