816.150—Roads: general.
(a) Road classification system.
(1)
Each road, as defined in § 701.5 of this chapter, shall be classified as either a primary road or an ancillary road.
(b) Performance standards.
Each road shall be located, designed, constructed, reconstructed, used, maintained, and reclaimed so as to:
(1)
Control or prevent erosion, siltation, and the air pollution attendant to erosion, including road dust as well as dust occurring on other exposed surfaces, by measures such as vegetating, watering, using chemical or other dust suppressants, or otherwise stabilizing all exposed surfaces in accordance with current, prudent engineering practices;
(3)
Control or prevent additional contributions of suspended solids to stream flow or runoff outside the permit area;
(4)
Neither cause nor contribute to, directly or indirectly, the violation of State or Federal water quality standards applicable to receiving waters;
(6)
Prevent or control damage to public or private property, including the prevention or mitigation of adverse effects on lands within the boundaries of units of the National Park System, the National Wildlife Refuge System, the National System of Trails, the National Wilderness Preservation System, the Wild and Scenic Rivers System, including designated study rivers, and National Recreation Areas designated by Act of Congress;
(c) Design and construction limits and establishment of design criteria.
To ensure environmental protection appropriate for their planned duration and use, including consideration of the type and size of equipment used, the design and construction or reconstruction of roads shall incorporate appropriate limits for grade, width, surface materials, surface drainage control, culvert placement, and culvert size, in accordance with current, prudent engineering practices, and any necessary design criteria established by the regulatory authority.
(d) Location.
(1)
No part of any road shall be located in the channel of an intermittent or perennial stream unless specifically approved by the regulatory authority in accordance with applicable §§ 816.41 through 816.43 and 816.57 of this chapter.
(e) Maintenance.
(1)
A road shall be maintained to meet the performance standards of this part and any additional criteria specified by the regulatory authority.
(2)
A road damaged by a catastrophic event, such as a flood or earthquake, shall be repaired as soon as is practicable after the damage has occurred.
(f) Reclamation.
A road not to be retained under an approved postmining land use shall be reclaimed in accordance with the approved reclamation plan as soon as practicable after it is no longer needed for mining and reclamation operations. This reclamation shall include:
(3)
Removing or otherwise disposing of road-surfacing materials that are incompatible with the postmining land use and revegetation requirements;
(4)
Reshaping cut and fill slopes as necessary to be compatible with the postmining land use and to complement the natural drainage pattern of the surrounding terrain;
(5)
Protecting the natural drainage patterns by installing dikes or cross drains as necessary to control surface runoff and erosion; and
(6)
Scarifying or ripping the roadbed; replacing topsoil or substitute material, and revegetating disturbed surfaces in accordance with §§ 816.22 and 816.111 through 816.116 of this chapter.
