THE MINERAL INDUSTRY OF LOUISIANA 
367 
 
 Capacity of Louisiana natural gas processing plants was increased 13 percent;
product output increased 19 percent. Ten new plants were completed and four
plants were closed. Storage space in salt dome caverns, to be used for recovered
plant liquids, was increased 3.5 million barrels (23 percent). 
 Of $653 million total tax collections in Louisiana for the fiscal year 1966—67,
$213 million was from the severance tax levied on minerals ($209 million
from mineral fuels). Gasoline, lubricating oil, special fuel, and other minerals-related
taxes accounted for an additional $94 million. 
 
 Legislation.—The Air Quality Act approved by the President on November
21, 
1967, could affect segments of Louisiana's mineral industry. According to
the Act, the U.S. Department of Health, Education, and Welfare will designate
air quality control regions—either interstate or intrastate—where
groups of communities have a common aIr pollution problem. The formula for
implementation of the new air pollution law closely follows the mechanism
established in the Water Quality Act of 1965—giving the States a chance
to set adequate quality standards, subject to imposition of Federal standards
if those of the States are not acceptable. 
 
 In May 1960, the U.S. Supreme Court decreed the Louisiana boundary to be
3 geographical miles seaward from the coast-
