Naval Air Station Patuxent River

Environmental Restoration Program Public Website
THE DEPARTMENT OF THE NAVY INVITES PUBLIC COMMENT ON THE
PROPOSED REMEDIAL ACTION PLAN FOR MUNITIONS RESPONSE SITE (MRS) UXO-001, HISTORICAL MUNITIONS DISPOSAL AREA
NAVAL AIR STATION PATUXENT RIVER, MARYLAND

 

In accordance with the requirements of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), Naval Air Station (NAS) Patuxent River invites public comment on the following document:

Proposed Remedial Action Plan (PRAP) for the Munitions Response (MR) Program Site UXO-001, Historical Munitions Disposal Area

MRS UXO-001 is located south of the NAS Patuxent River installation and consists of a private beach along the Chesapeake Bay, owned by the Cedar Cove Subdivision. The private beach is bounded to the north by Pine Hill Run; to the south by a community revetment structure; to the east by the low tide level of the Chesapeake Bay; and to the west by a wooded area. From approximately 1954 to 1974, NAS Patuxent River personnel discarded a variety of excess munitions, both live and inert, into the Chesapeake Bay. This practice was halted at NAS Patuxent River in 1974. NAS Patuxent River has responded to the appearance of munitions and explosives of concern (MEC) and material potentially presenting an explosive hazard (MPPEH) along the shoreline in and around the historic munitions disposal areas for over 30 years. The Navy conducted periodic surveys and cleanup activities of the former seaplane basin to the north and nearby beaches, including sweeps by divers as far as 300 feet offshore. In cooperation with USEPA and MDE, and in accordance with applicable guidance and consultation, the Navy performed additional investigations at MRS UXO-001 in 2018 to evaluate the potential extent of MEC and MPPEH and to assess the potential risks to human health.

The findings of the Remedial Investigation/Feasibility Study (RI/FS) at MRS UXO-001 indicate it is highly unlikely that MEC and MPPEH are present at the private beach resulting from historical disposal operations immediately to the north. Furthermore, to address any uncertainty the Navy proposes the most conservative approach to ensure protection of human health and assumes the potential for MEC and MPPEH to be present. Therefore, “Action” is proposed for institutional controls at the private beach to inform residents and visitors of the potential hazard of the presence of MEC and MPPEH is proposed for MRS UXO-001.


Public comment begins on February 1, 2023, and closes on March 2, 2023. A public meeting is scheduled for 6:00 p.m. on March 8, 2023, at the Frank Knox Employee Development Building, Building 2189, Room 100, to present the PRAP for MRS UXO-001 and answer any additional comments or questions.

PRAPs are issued as part of the Navy ER Program. The purpose of a PRAP is to describe the background and rationale for the selection of the remedy proposed by the Navy and U.S. Environmental Protection Agency (EPA). The PRAP includes solicitation of public comments on the remedy.

The public is encouraged to comment on the PRAP. The final remedy will be selected only after the public comment period has ended. An alternative remedy may be selected for MRS UXO-001 only after all comments have been received from the public. Relevant environmental documents for MRS UXO-001, including final technical reports and the PRAP, are available at:

Background

NAS Patuxent River Location Map

NAS Patuxent River is located in St. Mary’s County, Maryland, approximately 65 miles southeast of Washington, D.C. The facility encompasses approximately 7,900 acres, including both the primary NAS parcel at the confluence of the Patuxent River and the Chesapeake Bay, and Webster Field Annex, an outlying parcel located in St. Inigoes, Maryland, approximately eight miles south of the NAS.

NAS Patuxent River is bounded on the north, east, and southeast by more than 11.7 miles of shoreline, ranging from sandy beaches to tidal marshes. Maryland State Highway 235 and the town of Lexington Park, an unincorporated community, border the station to the west and southwest.

NAS Patuxent River was commissioned on April 1, 1943, in an effort to centralize widely dispersed air testing facilities that had been established prior to World War II. This consolidation effort was swift, and the farming operations at Cedar Point, Maryland, were replaced by flight test operations within a year after ground breaking for construction in 1942. The U.S. Naval Test Pilot School was established in 1958. In 1975, the Naval Air Test Center began to assume its role as the principal site for Naval Air Systems Command development testing. Test facilities were upgraded in the late 1970s, with some of the largest construction appropriations in the history of the base.

As a recipient activity during three successive rounds of base realignment and closure in the 1990s, NAS Patuxent River became the fastest-growing installation in the Department of Defense (DoD). This growth resulted in a large investment in new and renovated facilities and infrastructure at NAS Patuxent River. In addition to construction investments, the station obtained Webster Field Annex for use as an outlying airfield. As a result of the consolidation that occurred throughout the 1990s, the Naval Aviation Systems Team at NAS Patuxent River now hosts the full spectrum of acquisition management, research and development capabilities, air and ground testing and evaluation, aircraft logistics, and maintenance management for naval aviation.
