(Tetra Tech) to identify threatened, endangered, and BLM sensitive species (TES) and other plant and wildlife species that may occur within the Williams Draw Lease-By-Application (LBA) area and surrounding area (Project). In addition, Tetra Tech was tasked with providing a general assessment of the potential effects on TES from Project development. The Project area is located along the Book Cliffs in Emery County, Utah. From April to June 2016, Tetra Tech conducted a desktop analysis and field surveys for TES, and other wildlife and plant species identified in consultation with the BLM. The following targeted field surveys were conducted: raptor nest surveys, Mexican spotted owl (Strix occidentalis lucida) habitat assessment, and TES plant surveys, which were focused on Barneby reed-mustard (Schoenocrambe barnebyi), Jones cycladenia (Cycladenia humilis var. jonesii), Horse Canyon stickleaf (Mentzelia multicaulis var. librina) and Creutzfeldt-flower (Cryptantha creutzfeldtii). There were ten historic or current raptor nests within 0.5 mile of the Project area, including peregrine falcon (Falco peregrinus), golden eagle (Aquila chrysaetos), and great horned owl (Bubo virginianus). In 2016, two great horned owl nests and two golden eagle nests were active. Of these, only one great horned owl nest successfully fledged young. Based on field surveys, there is no suitable Mexican spotted owl habitat in the Project area due to the lack of moist, steep walled canyons. None of the targeted plant species were observed during field surveys, and no other TES plant or wildlife species were observed. The degree of impact from development of the Project would depend on the specific Project design. Possible impacts would include subsidence effects on hydrology and raptor cliff nesting habitat; human disturbance along the access road and surface facilities, vehicle collisions, and dust; and noise effects from the proposed ventilation shaft. Impacts to TES species would not occur because none of the species occur in the Project area. Tetra Tech August 2016 1 2016 TES and Other Plant and Wildlife Species Resource Inventory Williams Draw LBA 1.0 INTRODUCTION The United States Department of the Interior, Bureau of Land Management (BLM), Price Field Office contracted Tetra Tech, Inc. (Tetra Tech) to conduct a resource inventory for threatened, endangered, BLM sensitive (TES), and other plant and wildlife species within the Williams Draw Lease-By-Application (LBA) Project (Project) area. The purpose of the inventory was to identify the presence/absence of TES, and other plant and wildlife species within the Project area and to analyze potential impacts to species from the proposed development of the Williams Draw LBA and areas proposed for adjacent infrastructure. Tetra Tech completed a desktop evaluation and a field inventory for TES. This report describes the Project, physical setting, methods and results of the inventories, and analysis of impacts. The baseline data from this inventory may be used to support future analysis of federal actions in the Project area under the National Environmental Policy Act (NEPA). 1.1 Location and Project Description The Project area is located approximately 25 miles southeast of Price, Utah in northeastern Emery County along the Book Cliffs (Figure 1). The Project area encompasses the Williams Draw LBA area and includes land proposed to support associated infrastructure for underground coal mining, including access roads, surface facilities, and air shafts. The Project area totals approximately 7,554 acres, including the LBA area (approximately 4,200 acres) and the adjoining infrastructure area (approximately 3,354 acres). Surface land ownership in the Project area consists of State Institutional Trust Land Administration (SITLA) lands, private lands, and the federal lands managed by the BLM (Figure 2). The Project can be accessed via Utah Highway 6, and is located seven miles from the closest municipality, East Carbon, Utah. The Project area is located in all or portions of the following sections: Township 16 South, Range 14 East, Salt Lake Base and Meridian (SLBM), Utah Section 4, 5, 8, 9, 10, 15, 16, 21, 22, 23, 25, 26, 27, 34, 35, 36 Township 16 South, Range 15 East, SLBM, Utah Section 30, 31 Township 17 South, Range 14 East, SLBM, Utah Section 1, 2, 3, 12 Township 17 South, Range 15 East, SLBM, Utah
