The action addresses NOAA’s responsibilities under the NMSA to identify, designate, and protect areas of the marine and Great Lakes environment with special national significance due to their conservation, recreational, ecological, historical, scientific, cultural, archaeological, educational, or aesthetic qualities as national marine sanctuaries. ONMS developed four alternatives for the proposed designation and the FEIS evaluates the environmental consequences of each alternative under NEPA. The FEIS also serves as a resource assessment under the NMSA, documenting present and potential uses of the areas considered in the alternatives. NOAA’s preferred alternative (Alternative B) would designate an approximately 18 square mile bay area of waters and submerged lands of the tidal Potomac River for the protection of at- risk, nationally-significant shipwrecks and associated maritime cultural heritage resources. No significant adverse impacts to resources and the human environment are expected under any alternative. Long-term beneficial impacts are anticipated if the proposed designation is finalized.

This FEIS is also a resource assessment document that details the present and future uses of the areas identified for designation. The National Oceanic and Atmospheric Administration (NOAA) prepared this FEIS in accordance with the National Environmental Policy Act of 1969 (NEPA; 42 USC 4321 et seq.) as implemented by the Council on Environmental Quality regulations (40 CFR Parts 1500-1508), and NOAA Administrative Order (NAO) 216-6A, which describes NOAA policies, requirements, and procedures for implementing NEPA. Through the designation of MPNMS, NOAA seeks to protect nationally-significant maritime cultural heritage resources located entirely within the waters and submerged lands of the state of Maryland. This is a small bay area of the tidal Potomac River, which is adjacent to the Nanjemoy Peninsula of Charles County, Maryland. The area’s maritime cultural heritage resources include the fragile, historic remains of more than 100 World War I-era (WWI) U.S. Emergency Fleet Corporation (USEFC) wooden steamships known as the “Ghost Fleet,” other non-USEFC vessels of historic significance, and other related maritime debris fields. The archaeological and cultural resources cover centuries of history dating back from the earliest American Indian presence in the region, approximately 12,000 years ago. The area also contains resources from the Revolutionary War, Civil War, and two World Wars, as well as generations of Potomac fishing industries. The significance of the area is recognized through its listing on the National Register of Historic Places (National Register Listing Number 15000173, April 24, 2015). On October 7, 2015, NOAA initiated the public scoping process with the publication of a Notice of Intent in the Federal Register (NOI; 80 FR 60634). The NOI also announced NOAA's intent to fulfill its responsibilities under the requirements of the National Historic Preservation Act (NHPA). The public scoping period commenced in October 2015 and ended on January 15, 2016, during which time NOAA held public meetings and received both written and oral comments on the concept of designating a sanctuary. NOAA received approximately 186 comments during that scoping period, strongly supportive of designating a sanctuary within the state of Maryland. These public scoping comments were used by NOAA in preparing the proposed rule and the draft environmental impact statement and draft management plan (DEIS/DMP) associated with the proposed designation. On January 9, 2017, NOAA published a notice in the Federal Register announcing a proposed rule to designate approximately 52 square miles of waters and submerged lands encompassing and surrounding the Mallows Bay area of the tidal Potomac River as a national marine sanctuary (82 FR 2254). NOAA also provided public notice of the availability of the related DEIS/DMP (82 FR 2254; 82 FR 1733). All three documents (proposed rule, DEIS, and DMP) were prepared in close consultation with the state of Maryland and Charles County, Maryland. NOAA opened an 81-day public comment period for the three draft documents. NOAA received 1,120 written comments on the sanctuary proposal. During the public comment period, NOAA also held two separate public meetings in La Plata and Arnold, Maryland. Approximately 170 people attended the meetings, with 73 people providing verbal comments. Based on the public input, internal deliberations, 4 interagency consultations, and discussions with the state of Maryland and Charles County, NOAA made changes from the DEIS to the FEIS. In this FEIS, NOAA adopts Alternative B as the preferred alternative. The Alternative B boundary measures approximately 18 square miles. The Alternative B boundary begins at the mean high tide level on the Maryland side, extends across the Potomac River to the Virginia-Maryland state boundary line, and follows the boundary of the Mallows Bay-Widewater Historical and Archeological National Register District. The Alternative B boundary also closely matches the boundary submitted to NOAA by the governor of Maryland in the sanctuary nomination package. This smaller footprint contains a concentration of 142 historic shipwrecks, including USEFC vessels, vessels related to historic ship-breaking activities, other non-USEFC vessels of historic significance, and other related maritime debris fields. The area also includes nationally-significant Maryland state- recognized Indian Tribes heritage sites, remains of historic fisheries operations such as sturgeon and caviar industries, and Revolutionary War and Civil War battlescapes. NOAA is the lead agency for this action. NOAA’s Office of National Marine Sanctuaries (ONMS) is the implementing office for this action. The cooperating agency for the development of this FEIS is the U.S. Department of the Navy (DoN). Recommended Citation Office of National Marine Sanctuaries. 2019.
