RE: Spring Creek Pass, Permit Application File No. M-96-007, Preliminary Adequacy Review
Dear Mr. Ackerman:
CDOT's application package for the Spring Creek Pass operation has been forwarded to the Durango
Field Office, and a preliminary adequacy review was performed on the file. The Division's
comments from that review are listed below. Please respond to these comments as soon as
possible, or at least by April 15th, so that the May 2nd decision due date can be met.
Right off the bat, let me commend you for a well composed application package. It was thorough
and easy to review.
Exhibit C
1. The fence on the southern boundary is considered to be a permanent manmade structure
(unless it is dilapidated and non-functionall. Please submit a plan to ensure the stability of
this structure, or submit documentation of an agreement between CDOT and the USFS
regarding repair or replacement of the fence in the event that it is damaged.
2. CDOT indicates that the pit will operate on an intermittent status. Please submit the
information required by Rule 1 .13.7 for intermittent operations. Rule 1 .13.7 references Rule
1.13.5121 which lists the specific information required. Be aware that the annual reports for
this operation must indicate the condition of the pit at the time of cessation, what measures
have been and will be implemented to comply with reclamation and performance standards,
and CDOT's plans for resuming mining at this site.
Exhibit D
1. It appears that there will not be any overburden available for backfilling the highwalls.
Therefore, the Division assumes that the highwalls will be reduced to the proposed 3:1
slopes by cut and fill methods. If this is the case, CDOT must commit to leaving a 30 foot
buffer zone between the highwall crest and the permit boundary to allow for the cut and fill
operation without affecting land outside the permit boundary. The 30 foot buffer is figured
by assuming a maximum 20 foot highwall reduced to a 3:1 slope approximately 60 foot in
length. With the cut and fill method, the lower 30 foot of fill will come from cutting the
upper 30 foot (horizontal distance) from the crest of the highwall.
