The pond into which the woter from the present exploratory pit area <br />is to be pumped is not shown on the map. Please clarify the position of <br />this pond. <br />3. Any topsoil stockpiled for one growing season or Longer should be <br />-planted with a £ast-growing perennial grass cover (such as Western wheatgrass <br />at 6 Ibs.

The description of the terraciny of the pit is somewhCh confusing. <br />Please provide a cross-sectional diagram to scale in order to clarify this <br />matter. <br />5.
