~~ Henderson Permit #77-342 March 19, 1981 Page Eight directly because we feel there is very little likelihood of contamination. As indicated on page 6-35 of the existing permit, "...Ute Park is a tertiary lake bed with little continuity (stratification) in the sedimentary material due to multiple deposition and erosion processes. This complexly stratified material should preclude percolation or infiltration of water into the ground water system." Also, the soils map and description in the existing permit verifies that Ute Park soils are clayey. Also, the geology of the area indicates the existence of an impermeable dike across the mouth of Ute Park (which probably formed the tertiary lake). This dike would serve as an effective aquaclude to ground water movement, causing the water to surface at this point. There is no evidence of this occurring. 5. Has the State Engineer been contacted concerning the Lost Creek Reservoir? Yes F. Wildlife Information 1. Please describe the status of the wildlife monitoring program and summarize the data gathered to date. Refer to page 6-29 of the existing permit for a description of the monitoring program. The program was initiated in 1975 and is ongoing. In general, the study seems to indicate that the large mammal populations have increased since the survey was initiated. The survey also indicates that the animals are using our industrial area as a refuge. As with the water data, the reports are available for inspection at our offices if you desire. 2. Which areas of new disturbance are critical to wildlife, example - fawning areas, winter range, migration routes, etc.? The only lands requested in the amendment which protrude from existing affected lands are the interceptor canal and the additional reservoir. Although all AMAX land is used by large mammals, the most intensively used winter range and
