For reactive adhesives in which some of the HAP react to form solids and are not emitted to the atmosphere, organic HAP content is the mass of organic HAP that is emitted, rather than the organic HAP content of the coating as it is received.

You shall use liters (gallons) of solids used as a measure of relative surface coating activity over a representative period of operation. You may estimate the relative volume of coating solids used from parameters other than coating consumption and volume solids content. The determination of predominant activity shall accurately reflect current and projected coating operations and shall be verifiable through appropriate documentation. The use of parameters other than coating consumption and volume solids content shall be approved by the administrator. You may use data for any reasonable time period of at least one year in determining the relative amount of coating activity, as long as they represent the way the source will continue to operate in the future and are approved by the administrator. You shall determine the predominant activity at your facility and submit the results of that determination with the initial notification required by
s. NR 465.45 (1) (b). Additionally, you shall determine the facility's predominant activity annually and include the determination in the next semi-annual compliance report required by
s. NR 465.45 (2) (a).
NR 465.43 Note
Note: An example of parameters other than coating consumption and mass solids content for estimating the relative mass of coating solids used would be design specifications for the parts or products coated and the number of items produced.
NR 465.43(1)(c)2.
2. You may calculate and comply with a facility-specific emission limit as described in

c. If you elect to comply using the facility-specific emission limit alternative, then compliance with the facility-specific emission limit and the emission limits specified in
pars. (a) and
(b) for all surface coating operations constitutes compliance with this and other applicable surface coating NESHAP. In calculating a facility-specific emission limit, you shall include coating activities that meet the applicability criteria of the other sub-categories and constitute more than one percent of total coating activities. Coating activities that meet the applicability criteria of other surface coating NESHAP but comprise less than one percent of coating activities need not be included in the determination of predominant activity but shall be included in the compliance calculation.
NR 465.43(1)(c)2.a.
a. You are required to calculate the facility-specific emission limit for your facility when you submit the notification of compliance status required in
s. NR 465.45 (1) (c), and on a monthly basis afterward using the coating data for the relevant 12-month compliance period.
NR 465.43(1)(c)2.b.
b. Use Equation 1 of this subsection to calculate the facility-specific emission limit for your surface coating operations for each 12-month compliance period:
where:
Facility-specific emission limit is the facility-specific emission limit for each 12-month compliance period, kg (lb) of organic HAP per kg (lb) of coating solids used
Limit
i is the new source or existing source emission limit as specified in
s. NR 465.43 (1) applicable to coating operation, i, included in the facility-specific emission limit, converted to kg (lb) of organic HAP per kg (lb) of coating solids used, if the emission limit is not already in those units. All emission limits included in the facility-specific emission limit shall be in the same units.
Solids
i is the liters (gallons) of solids used in coating operation, i, in the 12-month compliance period that is subject to emission limit, i, as specified in
s. NR 465.43 (1). You may estimate the volume of coating solids used from parameters other than coating consumption and volume solids content, such as design specifications for the parts or products coated and the number of items produced. The use of parameters other than coating consumption and volume solids content shall be approved by the administrator.
n is the number of different coating operations included in the facility-specific emission limit
NR 465.43(1)(c)2.c.
c. If you need to convert an emission limit in another surface coating NESHAP from kg (lb) of organic HAP per kg (lb) of coating solids used to kg (lb) of organic HAP per liter (gallon) of coating solids used, you shall use the default solids density of 1.26 kg of solids per liter of coating solids (10.5 lb of solids per gallon of coating solids).
