### PART 1.0 FACILITYDESCRIPTION 1.3 Process Description ofModification Natural gas burners are to be installed onUnit 6 and Unit 7 to allow the units to operate at full load on 100% natural gas. In addition, a new natural gas-fired water bath heater will be installed at the existing pressure and flow conditioning station on-site, functionally replacing a smaller, existing natural gas heater currently located at an off-site regulating station. Anexisting on-site 75,000 gallon fuel oil tank that currently supplies fuel to the existing emergency generators and compressor as well as Units 6 and 7 will be decommissioned and replaced with a 5,000 gallon fuel oil tank that will supply the existing emergency generators and compressor only. All coal burners will be removed from Units 6 and 7 as part ofthe conversion to natural gas. Upon removal ofthe bumers, Units 6 and 7 will burn natural gas exclusively. Contemporaneously, with these projects, Units 1, 2, 3, 4 and 5 (the coal-fired units) andtwo associated 38,000 gallonfuel oiltanks atPlant Yates will be retired.
