Q311. For subpart AA in e-GGRT, can a reporter add multiple instances of makeup chemical use?

 

A311. No. The mill-wide total makeup chemical use is to be provided for the reporting year. Emissions associated with makeup chemical use are calculated based on the quantity of CaCO3 and/or Na2CO3 used at the facility for the reporting year (see section 98.273(d), Eq. AA-3). In the event of multiple instances of makeup chemical use, the reporter will need to keep a separate record of the quantity of CaCO3 and/or Na2CO3 used in each instance (or for each pulping line) in order to determine the mill-wide total quantity used for the reporting year.
