'The City of Redding, operating as the Redding Electric Utility (�REU�), owns the Clear Creek facility and the four units therein (Units 1, 2, 3 and 4). Prior to REU�s purchase of the Clear Creek facility, there was one steam turbine (Unit 4) fired by two boilers. EPA has determined that Steam Unit 4 was an exempt cogeneration unit, and that this exemption is still applicable. REU has failed to comply with the requirements of the Acid Rain Program in its operation of Units 1, 2, and 3. Additionally, units 2 and 3 are affected units subject to the requirements of Title IV. Units 2 and 3 each serve a generator with 31,039 KVA at 9 PF, and rated output of 27,750 kW. These units began operation after 1990 (sometime between October 27, 1994 and April 5, 1996) and are thus new utility units which are affected units. 40 C.F.R. ��72.2, 72.6(a)(3)(i).'
