WASHINGTON (AP) -- The Federal Emergency Management Agency is starting to bring some manufactured housing units to areas in New Jersey and New York that were hit hardest by Superstorm Sandy.

FEMA chief Craig Fugate says his agency has several hundred temporary homes in its inventory and has started moving them toward the most heavily damaged areas in those states.

He describes the units as mobile homes or manufactured housing approved by the Department of Housing and Urban Development.

Fugate says he doesn't know exactly how many homes will be moved into the area, where they will go or when residents may be able to start moving in.

FEMA was widely criticized after Hurricane Katrina in 2005 for using trailers that were later discovered to be contaminated with formaldehyde.
