# 97.57 Closing of general accounts.
(a) The NO<sub>X</sub> authorized account representative of a general account may instruct the Administrator to close the account by submitting a statement requesting deletion of the account from the NO<sub>X</sub> Allowance Tracking System and by correctly submitting for recordation under § 97.60 an allowance transfer of all NO<sub>X</sub> allowances in the account to one or more other NO<sub>X</sub> Allowance Tracking System accounts.
(b) If a general account shows no activity for a period of a year or more and does not contain any NO<sub>X</sub> allowances, the Administrator may notify the NO<sub>X</sub> authorized account representative for the account that the account will be closed and deleted from the NO<sub>X</sub> Allowance Tracking System following 20 business days after the notice is sent. The account will be closed after the 20-day period unless before the end of the 20-day period the Administrator receives a correctly submitted transfer of NO<sub>X</sub> allowances into the account under § 97.60 or a statement submitted by the NO<sub>X</sub> authorized account representative demonstrating to the satisfaction of the Administrator good cause as to why the account should not be closed.
