RULE 4 PERFORMANCE STANDARDS
RULE 4 PERFORMANCE STANDARDS
4.01 General Provisions
4.01.1 Scope and Objectives
Rule 4 establishes the minimum environmental protection performance standards adopted and
implemented under the Colorado regulatory program for surface coal mining and reclamation operations.
Colowyo has included information within this Section to insure that surface mining activities are
conducted in compliance with the performance standards and in a manner which maintains environmental
values.
4.02 Signs and Markers
4.02.1 Specifications
Colowyo has posted and will maintain all signs and markers required by this section. All of the signs are
of uniform design and can be easily seen or read. The signs are made either of metal or wood; they are
durable enough to withstand extreme climatic conditions that are inherent at the operations. The signs
conform with local ordinances and codes.
Colowyo will maintain signs and markers during the conduct of all activities to which they pertain.
4.02.2 Mine and Permit Identification Signs
Appropriate signs identifying the mine area are displayed at all major point of access to the permit
boundary from Highway 13/789 and Moffact County Roads 32 and 51. These signs indicate the name,
business address, and telephone number of Colowyo and identification numbers of mining and
reclamation permits.
4.02.3 Perimeter Markers
The perimeter of the permit boundary is marked with metal signs and/or wire fencing where appropriate.
Additional markers, if deemed necessary, include steel fence posts painted orange or capped with PVC
caps painted orange.
In 2014, working in cooperation with the Bureau of Land Management, Colowyo upgraded some existing
grazing fences within the permit boundary, and installed new fences along several portion of the permit
boundary south and west of the South Taylor Pit that were previously signed but not fenced. This
collective effort allowed greater visibility of Colowyo's permit boundary, Colowyo private properties,
and provided a greater public safety boundary on BLM lands adjacent to the active mining area.
4.02.4 Duration of Maintenance
Colowyo will maintain signs and markers throughout the life of the operation or post new signs and
markers as necessary.
