Logan Wash Mine Annual Report Permit No.: M-1977-424 Occidental Oil and Gas Company (OOGC) drilling a gas well on the bench. A storm-runoff stock watering basin was constructed at Area 10, the former Helo Pad, in 2004. The pond is to be used by a local rancher to water cattle. In 2005, a small flat area adjacent to the basin was being used by gas industry operators to park equipment. In the fall of 2005, OOSI reclaimed this area and constructed a security fence to prevent further disturbance. 2.2 Roads Table 2 refers to reclamation status of "Miscellaneous Access Roads" as described in the original permit. The acreage figures in the table are based on what acreage remains to be reclaimed as measured in the field. Field measurements for the "Mine Bench and Portal" roads indicate that 6.2 acres remain to be reclaimed at the end of the reporting period. The 6.2 acres of unreclaimed roads consists of 0.9 acres of the Lower Bench Road, and 5.3 acres of the Upper Access Road from the intersection of Logan Wash Road to the intersection of the Upper and Lower Bench Roads, 4,050 linear fr of which includes a 50-ft width due to outslope material that will need to be pulled back during reclamation. As discussed in Section 6.0, the Upper Access Road acreage may be removed from the permit if a separate BLM right-of--way is acquired by OOGC and a gas well is constructed on the Lower Bench. Disturbed acreage associated with the Logan Wash Road or the "tramroad" was originally shown in the mine permit to be 53.43 acres. U.S. Bureau of Land Management (BLM) records show that subsequent amendments to the right-of--way (COC-223027) resulted in aright-of--way of 58.6 acres; however, it is not clear that this was the actual disturbance. BLM records also indicate that the original right-of--way includes all of the Upper Access Road up to at least the Research Mine Bench portion of the road. The acreage amounts for roads (Area 13) in the original permit appear to include the acreage associated with the Upper Access Road. 2.3 Structures Surface structures that remain on site include, two vault structures, one on the Lower Bench and one on the Research Mine Bench, a capped and vented ventilation shafr, and the evaporation pond and associated detection vault. The two vault structures will remain as permanent structures on the mine site to manage and monitor mine water drainage. Subsurface structures include the Research Mine drainage pipeline, the L-1 mine water pipeline, the retort water pipeline, which extends from the sealed L-1 portal to the evaporation pond, and several monitoring wells. Two manholes, the Upper Manhole, and Lower Manhole, on the retort water pipeline are accessed periodically to measure pipeline flows. During the reporting period, OOSI, at the request of DRMS, prepared and submitted Amendment No. 1: Retort Water Pipeline and Evaporation Pond. Although these structures were permitted by the BLM and Garfield County and constructed in 1984, for unknown reasons the structures were not incorporated into the existing mine permit. OOSI is currently in the process of addressing adequacy issues submitted by DRMS. Because the amendment has not formally been accepted by DRMS, the retort water pipeline and evaporation pond will not be addressed as disturbed acreage in this annual report. Past reconnaissance efforts for well sites constructed in support of mine operations was conducted within the permit area and within Logan Wash. Eight wells were identified within this Western Water 8 Land, Inc.
