   (1g)   Exemptions.

      (a)   

         1.    A removal of material from the bed of a farm drainage ditch which was not a navigable stream before ditching is exempt from the individual and general permit requirements under this section unless the department finds that the proposed removal may have a long-term adverse effect on cold-water fishery resources or may destroy fish spawning beds or nursery areas.

         2.    Establish reasonable limitations on the location of the removal of material at the site affected by the activity.

      (b)    Notwithstanding par. (a), the rules under par. (a) 1. may not establish procedures that prohibit undertaking the removal of material or that render the undertaking of the removal of material economically cost-prohibitive.

   (1m)   Permits or contracts in lieu of exemptions. The department may decide to require that a person engaged in an activity that is exempt under sub. (1g) apply for an individual permit or contract, or seek authorization under a general permit if the department has conducted an investigation and visited the site of the activity and has determined that conditions specific to the site require restrictions on the activity in order to prevent any of the following:

      (a)    Significant adverse impacts to the public rights and interests.

      (b)    Environmental pollution, as defined in s. 299.01 (4).

      (c)    Material injury to the riparian rights of any riparian owner.

   (1r)   Exemption determinations.

      (b)    The department shall do all of the following within 15 days after receipt of a statement under par. (a):

         1.    Enter and inspect the site on which the activity is located, subject to s. 30.291, if the department determines such an inspection is necessary.

         2.    Make a determination as to whether the activity is exempt.

      (c)    If the department does not take action under par. (b), the department may not require at any time that the person proposing to engage in the activity apply for an individual permit, seek authorization under a general permit, or apply to enter a contract unless required to do so by a court or hearing examiner.

      (d)    If a statement under par. (a) is not given or if the statement does not give consent to inspect, the 15-day time limit under par. (b) does not apply.

   (1t)   General permits.

      (a)    The department shall issue statewide general permits under s. 30.206 that authorize any person to remove material for maintenance purposes from an area from which material has been previously removed.

      (am)    No person may be authorized to proceed under a general permit issued under par. (a) unless the person has demonstrated to the department that material has been previously removed from the area for which the person has requested authorization to proceed.

   (2)   Contracts and individual permits.

      (b)    The department may enter into a contract on behalf of the state for the removal and lease or sale of any mineral, ore, or other material from beneath the bed of a navigable water that the state may own if the contract will be consistent with public rights and if the navigable water will not be disturbed in the removal operation. A person seeking to enter into such a contract shall apply to the department. Each contract entered into under this paragraph shall contain any conditions that the department determines are necessary for the protection of the public interest and the interest of the state. Each contract entered into under this paragraph shall also fix the compensation to be paid to the state for the mineral, ore, or other material to be removed.

Should any doubt exist as to whether the state, in fact, owns such lake bed or stream bed such contract or lease shall be for such interests, if any, as the state may own. Title to the royalties to be paid when mining operations are begun shall be determined at such future time as royalties for ores so sold are paid or are due and payable.

      (bn)    For a removal that is not exempt under sub. (1g) and that is not subject to a general permit under sub.

(1) (a).

      (c)    The department shall issue an individual permit pursuant to an application under par. (bn) if the department finds that the issuance of the permit will be consistent with the public interest in the lake or stream.

      (d)    If an applicant for a permit under par. (bn) submits the application at least 30 days before the proposed date of the removal, the department may issue the permit for a period of up to 10 years.

         2.    “Line of navigation” means the depth of a navigable water required to operate a boat on the navigable water.

         3.    “Riparian zone” means the area that extends from riparian land waterward to the line of navigation as determined by a method that establishes riparian zone lines between adjacent riparian owners in a manner that equitably apportions access to the line of navigation.

      (b)    The department shall issue a statewide general permit under s. 30.206 on or before October 1, 2018, that authorizes a riparian owner to remove material from an inland water that is an impoundment or associated feature, as defined in rules promulgated by the department, without obtaining a permit under s. 23.24 (3) if all of the following apply:

         1.    The removal occurs within the riparian owner’s riparian zone.

         2.    The riparian owner’s riparian zone abuts a navigable water that is affected by a man-made impoundment, and the material removed is unconsolidated sediment that was deposited after the navigable water was affected by the impoundment.

         3.    The removal does not occur in a navigable water that is identified as an outstanding or exceptional resource water under s. 281.15.

         4.    The total amount of material removed does not exceed 50 cubic yards per year.

         5.    The material is removed to allow the riparian owner to navigate from the shoreline of his or her riparian property to the line of navigation.
