Hazmat Disposal Site L5

Hazmat Disposal Site L5 is a system of caves storing radioactive waste that connect L'Enfant Plaza and the Mall. One entrance is gained through the L'Enfant Plaza metro tunnels. A hole in the tracks leads you to the cave network below the subway tunnels. The other entrance is at the Southwest corner of the mall, near the Lincoln Memorial.

Denizens
The disposal site is home to one or two Super Mutants(Near the L'Enfant Plaza exit) and a number of Ghouls--including a small number of Glowing Ones and possibly a Reaver at higher levels with the Broken Steel add-on. There are also a number of bodies. There is no treasure of note.

Bugs
Upon entering and subsequently leaving the Hazmat Disposal Site, my character could not (depending if they were in sneak or regular mode) go back to regular mode if in sneak, or not go into sneak mode if in regular mode. This is a major bug, and I'm not sure if there's a patch for it. This can be fixed by re-loading the autosave after leaving the metro.
