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). Western Water & Land, Inc. 3
