470 MINERALS YEARBOOK, 1967 
 
engaged an engineering firm to determine the type of controls necessary to
enable its St. Louis plant to comply with St. Louis County's air pollution
control. program. During the study, the company tried to increase the efficiency
of its precipitators, which had not been able to keep emissions down to required
standards. . The major pollution problem in the cementmaking process is emission
of a fine white dust. 
 During 1967 the Southeast Missouri Mining & Milling Division of St.
Joseph Lead Co. actively continued a reforestation program and by yearend
had planted more than 250,000 trees in the various areas comprising its Missouri
operations. 
 The Petrolite Corp. of St. Louis organized a new subsidiary called International
Pollution Control, Inc., and also acquired International Disposal Contractors,
Inc., of Evansville, md. Petrolite's pollution control subsidiary will engage
in liquid and solid waste material disposal through wells, chemical treatment,
and incineration. The company will handle waste materials on a contract basis
and serve as a waste disposal utility for indutrial complexes. 
 The Water Resources Advisory Committee was established to assist the Water
Resources Board in preparing a comprehensive 5-year water and related land
resource plan. The planning effort will be coordinated with the development
of a Comprehensive State Plan funded under provisions of the Housing Act
of 1954, Section 701, as amended. A framework water plan, will be presented
as a chapter oi the Comprehensive State Plan, scheduled' for completion in
1970. The final 2 years of the water and related land resource planning effort
will be devoted to project economics, with emphasis on determining State,
politcal subdivision, or private responsibility .in implementing the desirable
features of~ the plan. The final 2-year period will also. consider legislative
and institutional changes that will contribute to implementation. 
 Final approval by the Federal Power Commission was given for electricity
generation at the Cannon Dam project in Ralls, Monroe, and Shelby Counties.
Land acquisition by the U.S. Army Corps of Engineers for the 26,000-acre
lake was procced~ng. The power production phase of Cannon Dam and Reservior
calls for a 
pumpback operation. A second smaller dam will be. built downstream from the
main dam; water flowing from the primary reservoir will generate power and
flow into the second reservior, then be pumped back into the primary reservoir
at night when power demand is low. 
 The Missouri Water Pollution Board completed action on water' quality standards
.for Missouri intrastate streams. The standards are intended to provide information
to the public on the water quality to be maintained in streams, and also
provide an effective enforcement tool. The Water Pollution Board established
149 monitoring stations throughout the State to detect changes in water quality
and to guide necessary corrective action where indicated. 
 The U.S. Geological Survey, Water Resources Division, successfully completed
a cooperative "time-of-travel" study on the Missouri River. The study was
undertaken ' primarily to gain data ' on travel of pollutants and protect
on of water users along the river. A fluorescent dye was used as a tracer
to follow particles of water along the 806-mile reach of the river. Results
of the study reveal that the effect of pollutants in the Missouri River can
be predicted with a high degree of accuracy. 
 The pollution problems and objectives of the coal industry in Missouri and
the abatement objectives and activitites of that industry were outlined.
Acid mine water drainage was the principal problem. 
 
 Legislation.—The 74th General Assembly of the Missouri Legislature
created a joint "Interim Committee on Mining" composed of five membe' s of'
the House and five members of the Senate. The Committee was instructed to
study the problem of mining in Missouri, the applicability of mine safety
legislation to apply to new equipment and methods of mining now utilized
in the several new deep lead and iron mines, and the need for regulation
and reclamation of open-pit and other methods of surface mining areas in
the State. The Committee was authorized to hold meetings and to prepare and
submit a report to the 75th General Assembly, together with the legislative
proposals it deems appropriate. Hearings were expected to start early in

1968.
