Where Feei represents the per manifest fee for each manifest submission type “i” and Nt refers to the total number of manifests completed in a year.

(b)

(1) If after four years of system operations, electronic manifest usage does not equal or exceed 75% of total manifest usage, EPA may transition to the following formula or methodology to determine per manifest fees:

Where Ni refers to the total number of one of the four manifest submission types “i” completed in a year and O&Mi Cost refers to the differential O&M Cost for each manifest submission type “i.”

(2) At the completion of four years of system operations, EPA shall publish a notice:

(i) Stating the date upon which the fee formula set forth in paragraph (b)(1) of this section shall become effective; or

(ii) Stating that the fee formula in paragraph (b)(1) of this section shall not go into effect under this section, and that the circumstances of electronic manifest adoption and the appropriate fee response shall be referred to the System Advisory Board for the Board's advice.
