 Chemical and petroleum industries accounted for $451.1 million, or approximately
63 percent of the total. Some of the largest investments in the chemicals
and petroleum category during 1967 were Cos-Mar, Inc.'s new petrochemical
plant at Carville to produce styrene monomer; Enjay Chemical Co.'s petrochemical
expansion at Baton Rouge to produce polyethylene plastic; Pittsburgh Plate
Glass Co.'s new plant at Lake Charles to produce mercury cell caustic and
chlorine; Freeport Chemical Co.'s new plant at Convent to produce phosphoric
and sulfuric acids; Commercial Sulvents Corp.'s plant addition at Sterlington
to produce ammonia; and Gulf Oil Corp.'s new plant at Donaldsonville to produce
anhydrclus ammonia, urea, and mixed fertilizer. 
 Three industrial bond issues were completed to build chemical plants: Iberville
Parish, $25 million for an 80-milliongallon-per-year methanol plant by Hercules
Corp.; West Baton Rouge Parish, $10 million for a new synthetic rubber plant
by Copolymer Rubber and Chemical Corp.; and Calcasieu Parish, $20 million
for a new polypropylene plant by Hercules Corp. 
 Other major investments of interest to the mineral industry, especially
the mineral 
fuels segment, included paper and paper products, $93.7 million; metals,
metal products, and machinery, $73.7 million (includes a $62.7 million bond
issue for a new aluminum plant at Lake Charles); stone, clay, and glass products
$14.9 million; and electric power $51.0 million. 
 The electric utility companies of Louisiana continued a large constructiOn
program. Louisiana Power and Light in late 1967 completed the remaining portion
of the 500,000-volt transmission grid interconnecting the 11 companies comprising
the South Central Electric Companies group. The company continued installation
of a third generating unit at Little Gypsy generating station, 25 miles upriver
from New Orleans in St. Charles Parish. 
 New Orleans Public Service, Inc., put its new 560,000-kilowatt generating
unit at the Michoud steam-electric generating station into commercial operation.

 The Federal Power Commission reported that eletric power generated in 1967
by Louisiana plants was 23,153 million kilowatt-hours. This was 6.7 percent
higher than the 1966 total compared with a national increase of 5.1 percent.
Louisiana's 1967 electricity output was about 1.9 percent of the national
output.
