Notice of Intent to Revise Boundaries
Expansion Map

On June 14, 2013, NOAA’s Office of National Marine Sanctuaries published a Draft Environmental Impact Statement (DEIS) and a Proposed Rule to consider expansion of Thunder Bay National Marine Sanctuary in Lake Huron. During the sanctuary's management plan review in 2006, NOAA received comments encouraging NOAA to expand the sanctuary's boundary to include the waters adjacent to Alcona and Presque Isle counties. Several local government and non-governmental organizations passed resolutions or submitted letters of support for boundary expansion. In 2007, the Thunder Bay Sanctuary Advisory Council adopted a resolution supporting expanded boundaries, and in 2012, three public scoping meetings were held.

Informed by these comments, NOAA prepared a DEIS and proposed rule. NOAA is now seeking public comment before final action is taken. Comments must be submitted by August 13, 2013.  You may submit comments on these documents, identified by NOAA-NOS-2012-0077, by any of the following methods:

In 2000, NOAA designated the 448-square mile Thunder Bay National Marine Sanctuary, which is jointly managed by NOAA and the state of Michigan. The sanctuary’s mission is to preserve nationally-significant shipwrecks and other maritime heritage resources through resource protection, education and research. Well-preserved by Lake Huron’s cold, fresh water, these shipwrecks span 150 years of Great Lakes maritime history.
