RULE 4 PERFORMANCE STANDARDS <br />4.23 AUGER AND HIGHWALL MINING <br />Colowyo does not plan to conduct auger or highwall mining activities; therefore, the requirements of this <br />Section are not applicable to this permit application. The Colowyo mine has identified truck and shovel <br />mining to be the most conducive method for coal extraction within the Collom Permit Expansion Area. <br />4.24 OPERATIONS IN ALLUVIAL VALLEY FLOORS <br />The field investigation described in Section 2.04.7 and 2.06.8 resulted in no identification of alluvial <br />valley floors in the general mining area which would be adversely affected by mining operations; <br />therefore, no special performance standards for operations in the alluvial valley floors are applicable to <br />this mining permit application, and no protection or remedial measures are proposed for compliance to <br />this Section. <br />4.25 OPERATIONS ON PRIME FARMLANDS <br />Since a negative determination of prime farmland was arrived at using the eligibility requirements <br />established for prime farmland under Section 2.04.12, these performance standards do not apply to the <br />present permit application. <br />4.26 MOUNTAINTOP REMOVAL <br />Based on the present data, no determination of mountain top removal has been made. When available, the <br />pertinent data will be delivered to CDRMS for a determination. <br />4.27 OPERATIONS ON STEEP SLOPES <br />Operations on steep slopes within the permit expansion area are not anticipated. Should operations of <br />steep slopes become a foreseeable action, Colowyo will submit an application for a variance from <br />approximate original contour. Any plans to develop operations on steep slopes will follow provisions <br />outlined within the original permit application. <br />4.28 FACILITIES NOT LOCATED AT THE MINESITE <br />This section is not applicable to the permit revision. All facilities used by Colowyo in their current <br />operations will continue to be used for the Collom mining operations. <br />4.29 IN SITU PROCESSING <br />This section is not applicable. <br />4.30 CESSATION OF OPERATIONS <br />4.30.1 Temporary <br />If, for any unforeseeable circumstances, temporary cessation of mining and reclamation operations at the <br />Colowyo operation becomes necessary for a period of thirty (30) days or more, Colowyo will submit to <br />the Division a notice of intention to temporarily cease or abandon mining and reclamation activities.
