The Department of the Navy, Naval Facilities Engineering Command Washington, and Naval Air Station (NAS) Patuxent River, in cooperation with the United States Environmental Protection Agency (USEPA) and the Maryland Department of the Environment (MDE), announces the availability of the following document for public review and comment: Engineering Evaluation/Cost Analysis (EE/CA) for Munitions Response Site UXO-002, OU-2 Former Skeet Ranges The EE/CA describes the Navy’s proposed “non-time-critical removal action (NTCRA)” to address environmental concerns at Operable Unit (OU)-2 (Former Skeet Ranges) a portion of Munitions Response Site UXO-002 (Former Small Arms Ranges) at NAS Patuxent River, St. Mary’s County, Maryland. The Navy intends to remediate lead and polyaromatic hydrocarbons (PAHs) in the soil at Former Skeet Ranges through excavation and off-site disposal of all wastes to eliminate the need for institutional controls at the site and to ultimately support unrestricted land use. The public is encouraged to comment on this EE/CA. The NTCRA will be implemented only after the 30- day public comment period has ended. An alternative removal action may be selected only after all comments have been received from the public. The EE/CA is available for public review at:
