(1) Until the amount of TR NOX Ozone Season allowances deducted equals the number of tons of total NOX emissions from all TR NOX Ozone Season units at the source for such control period; or
(2) If there are insufficient TR NOX Ozone Season allowances to complete the deductions in paragraph (b)(1) of this section, until no more TR NOX Ozone Season allowances available under paragraph (a) of this section remain in the compliance account.

The authorized account representative for a source's compliance account may request that specific TR NOX Ozone Season allowances, identified by serial number, in the compliance account be deducted for emissions or excess emissions for a control period in a given year in accordance with paragraph (b) or (d) of this section. In order to be complete, such request shall be submitted to the Administrator by the allowance transfer deadline for such control period and include, in a format prescribed by the Administrator, the identification of the TR NOX Ozone Season source and the appropriate serial numbers.
