Data shall be recorded monthly. [391-3-1-.02(6)(b)1 and 40 CFR 63.7525(k)] 5.2.29 Startup Boilers 1 and 2 (Emission Unit IDs SB01and SB02) must conduct a tune-up every 5 years to demonstrate compliance with the following paragraphs (a)-(g) below. Each 5-year tune-up must be conducted no more than 61 months after the previous tune-up. [40 CFR 63.7500(c) and 40 CFR 63.7540(a)(10), (a)(12), and (a)(13)] a. As applicable, inspect the burner, and clean or replace any components of the burner as necessary. The Permittee may delay the burner inspection until the next scheduled unit shutdown, but the Permittee must inspect each burner at least once every 72 months. At units where entry into a piece of process equipment or into a storage vessel is required to complete the tune-up inspections, inspections are required only during planned entries into the storage vessel or process equipment. b. Inspect the flame pattern, as applicable, and adjust the burner as necessary to optimize the flame pattern. The adjustment should be consistent with the manufacturer s specifications, if available. c. Inspect the system controlling the air-to-fuel ratio, as applicable, and ensure that it is correctly calibrated and functioning properly. The inspection may be delayed until the next scheduled unit shutdown. d. Optimize total emissions of CO. This optimization should be consistent with the manufacturer s specifications, if available, and with any nitrogen oxide requirement to which the unit is subject. e. Measure the concentrations in the effluent stream of CO in parts per million, by volume, and oxygen in volume percent, before and after the adjustments are made (measurements may be either on a dry or wet basis, as long as it is the same basis before and after the adjustments are made). Measurements may be taken using a portable CO analyzer. f. Maintain on-site and submit, if requested by the Division, a report containing the following: i. The concentrations of CO in the effluent stream in parts per million, by volume, and oxygen in volume percent, measured at high fire or typical operating load, before and after the tune-up of the boiler.

The type and amount of fuel used over the 12 months prior to the tuneup of the boiler, but only if the unit was physically and legally capable of using more than one type of fuel during that period. Units sharing a fuel meter may estimate the fuel used by each unit. g. If the unit is not operating on the required date for a tune-up, the tune-up must be conducted within 30 calendar days of startup. Page 4 of 7
