Logan Wash Mine Annual Report
Permit No. M-1977-424
2.2 Roads
2.2.1 Area 18: Logan Wash Access Road
Disturbed acreage associated with the Logan Wash Road or the"tramroad"was originally shown
in the mine permit to be 53.4 acres. This road extends from its intersection with Road 45 up
Logan Wash to and beyond the mine property. BLM records indicate that the original Logan
Wash Road right-of-way(COC-223027)was 58.6 acres and includes all of the Upper Access
Road up to the BLM-OOSI property boundary near the intersection of the Upper and Lower
Bench Roads. However,the OOSI reclamation plan included the Upper Access Road in Area 13,
Miscellaneous Access Roads.
A number of road turn-outs or cut and fill areas were constructed along Logan Wash Road and
these areas were included in revised versions of the mine permit. These areas are shown as"B1-
B-10" in Table 1. Reclamation of the main Logan Wash Road is not planned as this road is used
by the public and for energy industry access.
However, it is anticipated that the Upper Access Road will be reclaimed at the appropriate time.
The Upper Access Road extends from the main Logan Wash Road to the Research Mine and
beyond to the intersection with the Upper Bench Road and Lower Bench Road; it is estimated to
consist of 4.8 acres.
In the early 1980's OOSI realigned portions of the Logan Wash Road. The realignment took
place at several road segments, B1 through B10. The estimated acreage disturbance was
approximately 6.0 acres. All of these segments, except B2, B3, B7, and B8 were released in 1986.
Areas B2, B3, B7 and B8 have revegetated completely and will be submitted for warranty release
in the near future.
2.1.2 Area 13: Miscellaneous Access Roads
Documentation that defines the locations of the Miscellaneous Access Roads(Area 13) in detail
in the original reclamation plan is limited(see Table 2). Based on field observations, a number of
older roads have been reclaimed and are no longer used. These roads are located on the slope
above the Upper Bench and on the slope between the Upper Access Road and the Lower Access
Road(see Figure 4A). It is uncertain what portions of these roads have been released from
warranty, but it is assumed that some were released in 1986 because of their association with
other areas released at that time.
The remaining and existing roads that may have been included in Area 13 are: 1)Upper Access
Road,4.8 acres; 2) Lower Access Road, 1.8 acres; 3)Upper Bench Road, 1.4 acres; 4) Lower
Bench Road, 1.5 acres; and 5) Evaporation Pond Road, 1.3 acres. These acreages have been
estimated using GIS methods and assuming an average road width of 24 feet. Of these roads, the
Upper Bench Road and a portion of the Lower Access road were revegetated in 2005,and will be
submitted for warranty release in the near future. All other unreclaimed roads shall remain open
for use in 2017. Therefore,the total estimated unreleased acreage for Area 13, Miscellaneous
Access Roads, is 10.8 acres. This acreage is close to the acreage estimated by DRMS in January
2006(10 acres).
