Where:

E30day             =          30-day rolling average NOX emissions in tons per day for the account, computed for the preceding 30 days;

ED             =          total daily NOX emissions from each kiln located at the account, in tons per day, calculated according to the equation in subsection (b)(2) of this section;

K               =          number of kilns located at the account; and

N               =          preceding 30 days.
