Also Galleta grass is an important native specie of this region and should be included in a miz. Please commit to using the following seed mix or provide another mix for Division consideration.

Your outline of the sequence of each stage or phase includes scarifying if necessary. It is I e~~ understood that this scarifying is of the plant growth medium. If this is not so, please inform us t of the use of the scarifying operation. The Division recommends that the operator commit to ripping the pit floor to a depth of at least 6" - 8" prior to replacing topsoil. This will break up the shale and allow for better root and water penetration. This will also provide for some mixing with topsoil to prevent an abrupt hardpan-like barrier in the artificial soil profile. This operation should be very beneficial in helping to establish the grasses quicker and in a thicker stand. Please commit to this change or provide your plan to deal with having hard shale close to the surface and interfering with plant root growth and water penetration. Ripping with a t+~d grader would be satisfactory. . Exhibit 2 -Reclamation Costs The Division will calculate an estimate of the reclamation cost when the reclamation plan is finalized.
