Mr. William T. Davis - 5 - April 25, 1989
Rule 2.05.3(5)
Based on the soil description provided there may be as much as two (2) feet of
useable topsoil available. Therefore, it is recommended that a commitment be
made that a minimum of one foot will be stripped and fifteen (15) inches will
be the average s ripping depth. A final determination of stripping depth will
not be possible until the soil resources are mapped in more detail on the
proposed disturbance area. The preliminary recommendation is based on
achieving a final cover of at least 12 inches which should be sufficient to
meet the final land use of rangeland. Taking into account variables for rock
content, settling, compaction, erosion, operator error, etc., a final cover of
twelve (12) inches can probably be achieved by stripping, stockpiling, and
replacing fifteen (l5) inches of topsoil. This is a preliminary j
recommendation and if after further investigation of the soil resources it is
determined that a considerable area is composed of the Capulin soil, a deeper
stripping depth could be recamenended.
The application contains a statement which says, "These plants shall be
determined in cooperation with the local Soil Conservation Service". This
statement is inadequate and should be deleted from the text or have "and be
approved by the Division", on the end of the sentence. The operator may
obtain recommendations from the local SCS; however, he should submit a
temporary seed mix in a format analogous to the final revegetation seed mix.
Upon receiving this mix, it will need to be approved by the Division.

Rules 2.05.3(6)(a) and 4.08
Reference should be made in the narrative to the data supplied in Exhibits K,
L, and ht which address certain of the requirements of Rule 4.08. This
information is otherwise essentially lost to a reader,

There is no description of plans and equipment to be used to monitor the
blasts-as required by Rule 2.05.3(6)(a)(iv).
There-is no mention of plans for recording and reporting the results of
pre-blasting surveys as specified by Rule 2.05.3(6 )(a )(v ).
