R8: Yoast Mine Permit C-94-082, NOV C-96-018
Dear Ms. Crosby:
Seneca submits the following reclamation plan to the Division for
approval, as the abatPSnent of NOV C-96-018 to the Yoast Mine Permit
C-94-082. The current abatement deadline for this NOV is
reclamation plan submittal by January 23, 1997 and implementation
of the approved plan by February 22.
Based on earlier discussions between Seneca and Division personnel,
the Division felt Seneca needed to prepare a stability analysis of
the road cut slope along Routt County Road 27A, as part of the
reclamation plan. Seneca passed this information on to Mr. Paul
Draper, Director, Routt County Road & Bridge. Paul followed up our
phone conversation with a letter to me that was copied to Susan
McCannon, dated January 2, 1997.
His letter states that if in fact a slough did occur, Seneca would
be required to clear the material and reestablish the borrow ditch.
This has been a requirement by the county even before any
disturbance was conducted pertaining to the deadheading of the
dragline to Yoast. He also mentioned that the spring will be the
most likely time for slides, if in fact a problem would occur.
Seneca also contacted our geotechnical consultant, Northwest
Colorado Consultants Inc., to discuss this matter. Mr. Brian Len,
P.E. felt that if we were to conduct a proper stability analysis of
the existing road cut slope, it would be to wait until the spring
to obtain more accurate results of what exists in the field without
the snow cover on the slope. Therefore, Seneca proposes to wait at
the present time and monitor the slope to see what happens this
spring with the stability of the cut slope. If a slide should
occur, we will immediately contact Paul and Brian to determine the
best solution for remediating the problem.
Based on the Conditions of Administrative Permit 96-215 between
Seneca and the Routt County Regional Planning Commission, we will
reseed this slope in the spring. Using our currently approved
reclamation plan for the Yoast Mine, we will hand seed the entire
cut slope with Seed Mix No. 1B. The composition of Seed Mix No. 1B
