EPA has further identified specific compounds, within the chemical classes in the published list, to be considered for effluent standards. The thirteen elements in the published list, and their compounds, should receive emphasis in the environmental assessment of coal cleaning processes because of observed existence in coal.

Criteria for assessment of environmental pollutants from coal cleaning processes Author: R A Ewing ; Industrial Environmental Research Laboratory (Research Triangle Park, N.C.) ; Battelle Memorial Institute.

The high priority designation for pollutants may result from the environmental assess- ment criteria studies conducted as part of the overall coal cleaning environmental assessment program, or they may result from environ- mental assessment studies on other coal using or handling facilities.

Dry screening is used if air tables are to be used for coal cleaning. Wet screening is used where fine and ultrafine size streams are processed by wet cleaning processes.

Coal Cleaning Processes A number of approaches have been studied for non-destructive separations of coal from unwanted, associated mineral matter. Technological descriptions are presented for coal cleaning processes, e.g., size reduction, sizing, desliming screens, fine coal separation, jigs, dense-medium vessels, air tables, and wet concentrating tables.

Potential pollutants evolved from these processes and their control are identified. CONTROL TECHNOLOGY ASSESSMENT An assessment of pollution control technology for coal cleaning processes must consider control techniques for air pollution, water pollution, and solid waste.

Air Pollution Control Technology An evaluation was made of the various air pollution control technologies to determine their applicability for treating emissions from coal cleaning processes.
