MINERALS YEARBOOK, 1967 
 
 Employment and Injurics.—Overall mineral industry employment remained
unchanged and constituted 1.1 percent of the nonagricultural labor force,
according to the Mississippi Employment Security Commission. Employment in
petroleum and natural gas industries dropped 2.0 percent and constituted
82.5 percent of the labor force in mineral industries. 
 Two men were killed and one was seriously injured in a chemical plant explosion
in Jackson County. 
 
 Legislation.—An act passed in 1966 resulted in the establishment of
the Mississippi Air and Water Pollution Control Commission in 1967. Its function
is to control, prevent, and abate pollution of the air 
and of the surface and underground waters of the State. 
 The Bartlesville Office of Mineral Resources assisted in formulating water
quality criteria for the State's interstate and coastal waters, as promulgated
by the Commission. 
 
 Transportation.—International Paper Co., which transports 3.5 billion
cubic feet of gas per year through its 16-mile, 6 %-inch-diameter line from
Louisiana to its Natchez plant, was ordered by the Federal Power Commission
to show cause why it should not be subject to FPC jurisdiction and why it
should not be required to obtain a certificate to continue operating the
gas tranSmission line.
