Minnesota Administrative Rules

7019.3030 METHOD OF CALCULATION.

Subpart 1.

Method hierarchy.

The owner or operator of an emission reporting facility, except one issued an option C or D registration permit under part 7007.1125 or 7007.1130 or a capped permit under parts 7007.1140 to 7007.1148, must calculate the facility's actual emissions using the methods listed in items A to D. The owner or operator of an air toxics reporting facility issued an option D registration permit or a capped permit must calculate air toxics emissions for each emission unit using the methods listed in items A to D, except that similar emission units may be aggregated. The methods are listed in a hierarchy of the most preferred method to the least preferred method. The most preferred method available must be used. Where more than one method is listed in the item, they are considered to be equal in the hierarchy and any can be used:

A.

part 7019.3040 (continuous emission monitor data);

B.

part 7019.3050 (performance test data);

C.

part 7019.3060 (VOC and air toxics material balance), 7019.3065 (mercury material balance), 7019.3070 (SO₂ material balance), 7019.3080 (emission factor), or 7019.3090 (enforceable limitations), as applicable; or

D.

part 7019.3100 (facility proposal).

Subp. 2.

Option B permit fees.

The owner or operator of 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):

A.

must calculate the facility's actual emissions using the methods listed in part 7019.3060; and

B.

must not consider the effects of pollution control equipment on emissions from the use of VOC-containing materials when calculating actual emissions for an emissions inventory.

Subp. 3.

Selecting calculation method.

For purposes of selecting a calculation method, a method is considered available if the conditions associated with the method in parts 7019.3040 to 7019.3100 are met. The method described in part 7019.3100 may be used if the proposal is submitted to the commissioner by September 1 of the first calendar year for which the emissions are being calculated. The commissioner must reject data submitted using the methods described in parts 7019.3040 to 7019.3090 if the conditions for the method are not fully met.

Subp. 4.

Reporting individual pollutants.

An owner or operator of a facility must report individual pollutants to the maximum extent feasible. If the owner or operator cannot report individual pollutants within a group, such as lead compounds or nickel compounds, the owner or operator must report total emissions as a group.
