4.03.1 Haul Roads. (OOnt'd.)
(5) (a)
The Orchard Valley Mine haul road is asphalt surfaced. The surface has
been proven to be sufficiently durable for the anticipated volume of
traffic and weight arxi speed of the vehicles.
The Orchard Valley West haul road is gravel surfaced. The surface has
been proven to be sufficiently durable for the anticipated volume of
traffic and weight and speed of the vehicles.
The Orchard Valley R-0-M coal stoc3q~ile haul road is gravel surfaced. The
surface is designed to be sufficiently durable for the anticipated volume
and weight and speed of the vehicles. COVCC constructs and maintains the
surface of this road to provide service Life as required by the mine
operations. ODVCC commits to tracking the utilization of this road and
reassessing the service life of the road prior to exceeding the truck-day
utilization projection defining the service life (refer to Supplemental
Geotechnical Engineering Study, Low Grade Coal Haul Road, Lambert and
Associates, Volume 6). Utilization records will be maintained and made
available to the Division for review upon request.
•
Twelve inches (12") of gravel was added to the bearing surface of the
Orchard Valley R-0-M coal stockpile haul road in accordance with the
design specifications detailed in the Lambert study during June, 1992.
The additional gravel provided a minimum three year service life based
upon the usage rates projected in the study. Utilization records have
been maintained since that time and are available for review at the mine.
(5) (b)
Asphalt and gravel are Division approved surfacing materials and do not
contain acid or toxic forming substances.
(6) (a)
COVCC owns and operates equipment capable of assuring proper maintenance
of shoulder, surface, parking and side areas, approach structures and
erosion control devices, and cut and fill section repairs as required.
The equipment includes: a motor grader, front end loaders, backhoes with
front end loaders, and a dump truck. Any major repairs that rewire
specialty equipment are performed by contractors.
COVGC will maintain the Orchard Valley West Mine haul road from the mine
site to the intersection of Steven's Gulch road. CDVCC will also maintain
Steven's Gulch road to the entrance of the existing Orchard Valley Mine
site. Appropriate maintenance will be continued in a regular manner as
identified by regular inspection.
•
Maintenance of the Orchard Valley RAM coal stockpile haul road will be
conducted in a regular manner as identified by periodic inspection.
(6) (b)
The Orchard Valley Mine haul road is maintained in a regular manner. Zhis
