AOC J – Former Operations Area Disposal Site
AOC J is an old disposal site of approximately 1.2 acres, draining into a
quebrada that leads to Vieques Sound. The area was used as a solid waste
disposal site associated with construction staging activities. The depth of
disposal appears to be 2 to 4 feet deep. It was used between the mid-1960s and
1973, after which the waste was removed from the site and placed in a municipal
landfill off base.
During a site visit conducted in 2000, 106-mm shell casings and 20-mm ammunition
boxes were observed, as well as visible debris consisting of scrap metal from
construction equipment, shell casings, glass fragments, and wood waste.
The Navy and the regulatory agencies agreed that the waste at AOC J poses an
unacceptable uncertainty regarding a potential future source of contamination
and, therefore, should be removed.
The wastes
were removed and properly disposed of in 2008. Confirmatory samples were
collected after the removal actions were completed, to ensure that the site is
left in a manner that is protective of human health and the environment.
