In 1883 Rose Island became part of the Naval Torpedo Station headquartered at Goat Island It was used to store munitions high explosives used for torpedo warheads gun cotton primers mines and torpedo warheads. Several buildings to house the above were constructed from 1900 to the 1940 as well as barracks, officers quarters, mess hall, scullery gallery, latrines, water tank, transformer building, utility lines, and other support facilities. TNT Filling House Bldg 31 was constructed in 1918 to fill torpedo warheads. In 1943 three anti-aircraft batteries were installed on the island. The type of ordnance installed within the anti-aircraft gun emplacements were 90mm anti aircraft guns and 50 caliber machine guns. Active use of the 12.5 acre portion of the island ceased within few years of WW II. No significant use of this area was made during the 1950s until the Coast Guard gained use and operated the lighthouse until 1974. Except as stated the area was not under other than DOD control during the period of DOD ownership and use. Since owning the 12.5 acre parcel of land on Rose Island, CMTS has not used the underground or aboveground fuel storage tanks. Since owning the 1.5 acre parcel of land on Rose Island the City of Newport has begun to renovate the lighthouse. The City plans on using the site for recreational purpose.

Update (Dec. 5, 2017): We have changed the source of the installation cost data after being notified by the Department of Defense that they erroneously reported their own cost figures on the DERP website. We are now displaying the costs the department says are the most accurate available, from the Pentagon’s DERP database that we received in a FOIA request.
Note: The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.
