(b) The construction and maintenance of bridges by the department of transportation in accordance with s. 30.2022.

(c) Material injury to the riparian rights of any riparian owner.
(6p) Costs. If the department requires a person who replaces a culvert to apply for an individual permit or seek authorization under a general permit under sub.

(6) (d), and if the department includes conditions in the individual permit or under the general permit that are different than the conditions in the permit issued for the culvert being replaced, the department may not impose a fee for the individual permit or for authorization under the general permit and shall reimburse that person, from the appropriation under s. 20.370 (8) (ma), for his or her reasonable costs incurred in complying with the different conditions in the permit.
