DELTA SHIPYARD Houma, Louisiana

Terrebonne Parish

(?) Site Location:

The former Delta Shipyard is located at 200 Dean Court in southeastern Houma, Terrebonne Parish, Louisiana. The
facility is located in a mixed industrial and residential area south of the city of Houma, Louisiana.

xl Site History:	

Delta Shipyard was a cleaning and repair facility for small cargo boats, fishing boats, and oil barges. Oily waste from
the cleaning process was stored in several unlined earthen pits used as evaporation ponds. These pits were reportedly
also used to dispose of oil field drilling material. Delta Shipyard was owned by Delta Ironworks, Inc. The entire
property consisted of 165 acres and was home to seven divisions of Delta Ironworks, including Delta Shipyard.
During the 1970s and 1980s, the property changed hands through several mergers and sales. In January 2012, the
Louisiana Department of Environmental Quality asked the EPA for assistance in evaluating this site.

I Site Contamination/Contaminants:

Wetlands are contaminated with arsenic, antimony, anthracene, barium, benzene, cadmium, chromium, ethylbenzene,
fluorene, lead, manganese, mercury, 2-methylnaphthalene, naphthalene, phenanthrene, pyrene, o-xylene and m,p-
xylene to the surface water pathway. In addition, three evaporation pits containing greater than 30,000 cubic yards of
hazardous material are located in a wetland and may potentially release waste to nearby waterways.
