Current through August 26, 2024
Section NR 428.24 - Recordkeeping and reporting
(1) EMISSION LIMITATIONS. The owner or operator of an emissions unit subject to an emission limitation in s. NR 428.22 shall meet the recordkeeping and reporting requirements of this subsection.
(a)Recordkeeping. In addition to the recordkeeping requirements of ss. NR 439.04 (1) and (2) and 439.05, the owner or operator shall maintain records of all of the following:
1. The applicable emission limit and calculated heat input weighted emission limit for an emissions unit demonstrating compliance for multiple fuels.
2. The 30-day rolling average emission rate on a daily basis determined according to s. NR 428.23.
3. The total monthly heat input for each fuel or the emissions unit output, as applicable, in measurement units consistent with the units of the applicable emission limitation.
4. The emissions unit's annual and ozone season capacity utilization in measurement units consistent with the units of the applicable emission limitation.
5. For the emissions monitoring system required in s. NR 428.23 (1) (b) on an annual and on an ozone season basis, records of performed maintenance, hours of malfunction and necessary repairs, and the percent of hours the monitoring system operated during the emissions unit's operating hours.
(b)Reporting. In the reports to the department required under s. NR 428.25 (1), if applicable, or s. NR 439.03 (1) (b), the owner or operator shall submit the following information:
1. A certification of compliance with the applicable emission limitation in s. NR 428.22 or identification of the periods of non-compliance, with a quantification of the excess emission rate and the excess mass emissions.
2. For each calendar month, the highest 30-day rolling average emission rate. The emissions data shall be reported in the measurement units of the applicable emission limitation.
3. The emissions unit's annual and ozone season total operating hours, capacity utilization, and the percent operation of any required continuous emissions or combustion monitoring systems during the hours the emissions unit was operating.
(c)Secondary fuel usage recordkeeping. The owner or operator claiming exemption from the requirements under s. NR 428.22 pursuant to s. NR 428.22 (3) shall keep a record of all of the following:
1. Each occurrence when the fuel denoted under s. NR 428.22 (3) was burned.
2. The reason for each occurrence when the fuel denoted under s. NR 428.22 (3) was burned.
3. The monthly and yearly total hours of operation for each fuel used as specified under s. NR 428.22 (3).
4. Other relevant information as required by the department.
(2) GENERAL EXEMPTION UNIT. The owner or operator of an emissions unit claiming exemption under s. NR 428.21 (1), shall record operational parameters necessary to demonstrate the unit's qualification for the exemption status.
(2m) RECIPROCATING ENGINES. The owner or operator of an emissions unit claiming exemption under s. NR 428.21 (2m) (a) 2., shall maintain a record of horsepower-hours of operation for each ozone season. Measurement of horsepower-hours may be determined using recorded data which can be directly related to actual horsepower-hours of operation of the engine including actual total operating hours, fuel consumption, or load and duration measurements.
(3) LOW OPERATING UNIT. The owner or operator claiming a low operating unit exemption for an emissions unit under s. NR 428.21 (2), shall maintain a record of the unit's applicable fuel heat input or production output, as applicable, the unit's total capacity utilization on an ozone season and on an annual basis for each calendar year and calculations demonstrating the unit's qualification for the exemption.
(4) OTHER REGULATED UNIT. The owner or operator claiming a regulated emissions unit exemption for an emissions unit under s. NR 428.21 (3), shall maintain a record of all performance tests, calculations, assumptions and methods used to determine the emissions unit's potential emissions.
