(b) Outgoing canal freight delivered at any canal terminal during the navigation season will be allowed a free storage period of 20 days. Regular storage rates will be charged for each 10-day period, or fraction thereof, elapsing after such free period.

1. (1) Incoming canal freight delivered at any canal terminal during the navigation season will not be charged a storage fee if such freight is entirely removed from the canal terminal within 20 days from delivery.
2. (2) If any part of such freight remains at the canal terminal longer than 20 days, the regular storage rate for one 10-day period will be charged against the entire cargo. This charge will cover the first 20 days of occupancy of the canal terminal. Thereafter, the regular storage rates will be charged for each 10-day period, or fraction thereof, with such rates applied to the amount of freight as remains at the terminal at the commencement of each 10-day period. All of the terminals shall be cleared of such storage by February 1st, unless the Canal Corporation grants a permit to extend such storage period.
