Abstract
A cover material for a bulk material pile and method for applying the cover material are disclosed. The cover composition is free of fiber, clay, cement and pozzolanic material and comprises: 95 to 99.75 percent by weight water, 0.25 to 5 percent by weight of a water dispersible cellulosic polymer; and sufficient acid to maintain the pH of the solution between 1.0 and 6.0.

A method of providing a cover to a bulk material pile, the method comprising:
- a. providing a cover composition free of fiber, clay, cement and pozzolanic material, said composition comprising:
- 95 to 99.75 percent by weight water
- 0.25 to 5 percent by weight of a water dispersible cellulosic polymer;
- and
- sufficient acid to maintain the pH of the solution between 1.0 and 6.0;
- b. applying the cover composition onto the bulk material pile;
- and
- c. allowing the composition to harden to provide a cover to at least a portion of the bulk material pile.
A mixture for covering waste piles, said mixture being free of fiber, clay, cement and pozzolanic material, said mixture comprising:
- 95 to 99.75 percent by weight water
- 0.25 to 5 percent by weight of a water dispersible cellulosic polymer;
- and
- sufficient acid to maintain the pH of the solution between 1.0 and 6.0.
A bulk material cover composition consisting essentially of:
- 95 to 99.75 percent by weight water that does not meet US EPA standards for potable water;
- 0.25 to 5 percent by weight of a water dispersible cellulosic polymer;
- and
- sufficient acid to maintain the pH of the solution between 1.0 and 6.0.
