This EUG includes boilers that are subject to 40 CFR 60, Subpart D (Fossil-Fuel-Fired Steam Generators for Which Construction is Commenced After August 17, 1971).
This EUG includes emission units that have combustion emissions, but are not subject to an NSPS or a NESHAP performance standard. PO-1, the catalytic oxidizer, will be replaced by a regenerative thermal oxidizer (RTO). PM-11, 12, 13, and 14 will have their burners replaced. The first table following identifies existing equipment, while the second table describes the changes to be made to the emission source within the unit.
Existing Units
The Coal Preparation Plant, including all emission units, such as coal processing and conveying equipment and coal storage systems, is subject to the provisions of 40 CFR 60, Subpart Y, which affects coal preparation plants that process more than 200 tons per day. The coal storage pile, including railcar unloading and stacking equipment leading to the pile, are not subject to this rule, and are not included in this EUG. The detailed equipment list found in the Memorandum associated with the pending Part 70 permit is not repeated here, because there are no physical changes or changes in the method of operation. Increased use of coal as boiler fuel is possible, but this does not affect the equipment.
