Locations of Gas Plants and Other Coal-tar Sites in the
THE STATE OF LOUISIANA
manufactured gas history is both varied and complicated. Gas was produced at New
Orleans as early (1822) as it was in our larger, industrialized cities; the
author’s count of its own coal-tar sites currently 20, and the number should
prove to be considerably larger.
of Hurricane Katrina have enhanced our understanding of the geologic
complexities of the soft, youthful, unconsolidated and geomorphically
discontinuous soils of the State’s Mississippi River sites. The earliest human
remains were discovered (1822) at a depth of 5.5 m bgs in excavation of the
gasholder pit of the Locust St. gasworks. New Orleans’ gas company changed hands
six times (1907-1917) and the constraints of gas distribution technology makes
site characterization a demanding task. Among the out-of-State owners were Stone
& Webster(Baton Rouge, Lake Charles) and EBASCO (New Orleans). Town gas plants
appear to have been limited to New Orleans (1890 population of 290,000),
Shreveport (12,000), Baton Rouge, Lake Charles and Lafayette, as well as
Jennings (4,500 in 1920s). Considering the general lack of industry in the pre
natural-gas era, the potential for producer gas plants. Outside of New Orleans,
natural gas was first discovered in developable quantities at Sterlington in
1924 and eventually led to termination of most manufactured gas plants by the
early 1930s; 1928 for New Orleans.
Louisiana, the proximity of wood needing humid-climate preservation brought
forth (1895 with a surge at 1900-1910) creosote pressure wood-preservation
plants (32 now known; five SUPERFUND NLP), most of which chose direct discharge
options for managing their spent impregnation solutions. As in other southern
States, once established, with rail connections, other wood preservers tended to
put up plants in the same areas.
Of all U.S.
physiographic provinces the geologic terranes of this State are most unfriendly
to the current RP trend toward risk-avoidance of comprehensive characterization
and realistic remedial action.
