1. After completion of the inventory prescribed in title 2 of this article with respect to any tidal wetland, no person may conduct any of the activities set forth in subdivision 2 of this section unless he has obtained a permit from the commissioner to do so. The permit issued by the commissioner shall be in addition to, and not in lieu of, such permit or permits as may be required by any municipality within whose boundary such wetland or portion thereof is located.

2. Activities subject to regulation hereunder include any form of draining, dredging, excavation, and removal either directly or indirectly, of soil, mud, sand, shells, gravel or other aggregate from any tidal wetland; any form of dumping, filling, or depositing, either directly or indirectly, of any soil, stones, sand, gravel, mud, rubbish, or fill of any kind; the erection of any structures or roads, the driving of any pilings or placing of any other obstructions, whether or not changing the ebb and flow of the tide, and any other activity within or immediately adjacent to inventoried wetlands which may substantially impair or alter the natural condition of the tidal wetland area.

3. The depositing or removal of the natural products of the tidal wetlands by recreational or commercial fishing, shellfishing, aquaculture, hunting or trapping, shall be excluded from regulation hereunder, where otherwise legally permitted.

4. Activities, orders, and regulations of the department of health or of units of local government with respect to matters of public health shall be excluded from regulation hereunder, except as hereinafter provided. Copies of all such public health orders and regulations affecting tidal wetlands shall be filed with the department of environmental conservation. The commissioner may require modification of such orders or regulations if he deems it necessary to implement the policy of this act.

5. The commissioner shall review all current mosquito control projects to determine whether they are having any adverse impact on tidal wetlands. Where any adverse impact is found, the commissioner following a public hearing, may require modification of such projects if he deems it necessary to implement the policy of this act.

6. Where the dredging or filling is in the navigable waters of the state or is for the reconstruction or repair of certain dams and docks, and where such activity also substantially affects tidal wetlands, any person undertaking such activity must seek permission under this act as well as under any other applicable law.
