Our review does not include BLM's review, which will be sent to <br />you under separate cover once we have received their comments. Please respond <br />no later than September 20, 1985. <br />Exhibit B - Mining Plan <br />~~~h Is all previous disturbance at this site included in this application? If <br />not, is it possible to include these areas so that some form of reclamation <br />can be accomplished on these previously mined area? <br />,~e~~1R, Where will the topsoil stockpile be located? If the pile lasts for more <br />.,~c~P than one growing season, the pile should be sloped to no steeper than 3h:ly <br />and seeded to protect soil quality and quantity. <br />\~;;` ~3~.

To insure proper reclamation of this site, it is necessary to <br />reduce these slopes to considerably less than vertical.
