7019.3040 CONTINUOUS EMISSION MONITOR (CEM) DATA.

A.

If an emission reporting facility or a facility issued an option B registration permit under part 7007.1120 that chooses to be assessed a fee under part 7002.0025, subpart 1, item C, subitem (1), has collected emissions data through use of a CEM in compliance with the preconditions in subitems (1) and (2), the owner or operator must report that data to the commissioner in the facility's emission inventory. The emission inventory submitted must be based on all the CEM data. The requirements in subitems (1) and (2) must be met:

(1)

the CEM has been certified by the commissioner; and

(2)

the CEM data have not been rejected by the commissioner due to failure by the owner or operator to comply with parts 7017.1002 to 7017.1220; all applicable permit conditions; and any other applicable state or federal laws pertaining to CEM operation.

B.

An emission inventory submitted according to item A must include:

(1)

the total operating time of the applicable emission unit and the total operating time of the CEM;

(2)

an explanation of how the emissions were calculated based on the CEM data. Except for facilities subject to part 7017.1020, for periods when the CEM is down and the emissions unit is operating, missing emissions data must be substituted with CEM data recorded during a representative period of operation of the emissions unit, and, if applicable, of the control equipment operation during the same calendar year for which the inventory is being submitted. The CEM must have recorded data for at least 90 percent of the hours the emission unit was operated for the calendar year for which the inventory is being submitted. If substitute CEM data meeting these conditions is not available, emissions during periods of CEM downtime must be calculated using the next highest available method on the hierarchy of methods listed in part 7019.3030; and

(3)

for facilities subject to part 7017.1020, substitute CEM data in accordance with Code of Federal Regulations, title 40, part 75.
