      dirt, soil, or other materials are to be removed from an area
      acquired by title or easement, whether by agreement or condemnation,
      for use in the project, adequate provision shall be made for the
      salvage of topsoil from the area for use in the restoration of the
      specified critical areas of the project by replacement of salvaged
      topsoil, by fertilizing and mulching if necessary, or by other
      appropriate measures to provide vegetative cover to prevent erosion,
      including filling or covering the area with compost, except where a
      lake or subwater table conditions exist, where deep loess is present,
      or where outside ditch bottoms and backslopes are present in rock cut
      areas.  This section shall not apply to borrow pits covered by
