On September 16, 2014, pursuant to section 304 of the National Marine Sanctuaries Act (NMSA) and the Sanctuary Nomination Process (79 FR 33851), a coalition of community groups submitted a nomination asking NOAA to designate Mallows Bay-Potomac River as a national marine sanctuary. The Mallows Bay area of the tidal Potomac River being considered for designation as a national marine sanctuary is an area 40 miles south of Washington, DC, off the Nanjemoy Peninsula of Charles County, MD. The designation of a national marine sanctuary would focus on conserving the collection of maritime heritage resources (shipwrecks) in the area as well as expand the opportunities for public access, recreation, tourism, research, and education. NOAA completed its review of the nomination in accordance with the Sanctuary Nomination Process and on January 12, 2015, added the area to the inventory of nominations that are eligible for designation. On October 7, 2015, NOAA issued a notice of intent to begin the designation process and asked for public comment on making this area a national marine sanctuary. Designation under the NMSA would allow NOAA to supplement and complement work by the State of Maryland and other federal agencies to protect this collection of nationally significant shipwrecks.
