In this Request for Amendment No. 4, PacifiCorp seeks to expand the EFSC-certificated facility boundary to include the Grants Pass-Sams Valley Transmission Line and the Sams Valley Substation for the Sams Valley Reinforcement Projects (Project). Exhibit Q was prepared to meet the submittal requirements for the Project, per Oregon Administrative Rule (OAR) 345-021-0010(1)(q), related to Oregon listed threatened and endangered (T&E) species. 1.1 Analysis Area The Analysis Area for all species in Exhibit Q is defined as the Site Boundary, as described in the Written Request for Amendment #4 Eugene–Medford 500 kV Transmission Line, plus a 5-mile buffer, as defined by OAR 345-001-0010(59)(a). Site Certificate Condition Compliance PacifiCorp recommends the following new conditions for this resource to ensure compliance with the T&E Species Standard: • Threatened and Endangered Condition 1: During construction and operation, the site certificate holder shall not conduct work activities that produce loud noises above ambient levels within specified distances (see Table below) of any active northern spotted owl nest site during the critical early nesting period, March 1 – June 30, or until two weeks after the fledging period. This seasonal restriction may be waived if protocol surveys have determined the activity center is not occupied, owls are non-nesting, or owls failed in their nesting attempt. The distances listed in the table may be shortened if significant topographical breaks or blast blankets (or other devices) would muffle sound between the work location and nest sites. Work Activities that Produce High Ambient Levels Activity Zone of Restricted Operation Heavy equipment (including non-blasting quarry operations) 105 feet Chain saws 195 feet Impact pile driver, jackhammer, rock drill 195 feet Small helicopter or plane 360 feet1 Type 1 or Type 2 helicopter 0.25 miles1 Sams Valley Reinforcement Projects 1 Request for Amendment to Site Certificate EXHIBIT Q: THREATENED AND ENDANGERED SPECIES Work Activities that Produce High Ambient Levels Activity Zone of Restricted Operation Blasting; 2 pounds of explosive or less 360 feet Blasting; more than 2 pounds of explosives 1 mile 1. If less than 1,500 feet above ground level. • Threatened and Endangered Condition 2: Prior to construction, the Site Certificate holder shall conduct state listed Threatened and Endangered plant species surveys on those portions of the Site Boundary that have not been previously surveyed, if potential habitat may exist. If state listed Threatened and Endangered plant species are found during surveys, they will be flagged and avoided where possible. Identification of Species – OAR 345-021-0010(1)(q)(A) OAR 345-021-0010(1)(q) Information about threatened and endangered plant and animal species that may be affected by the proposed facility, providing evidence to support a finding by the Council as required by OAR 345-022-0070. The applicant shall include: OAR 345-021-0010(1)(q)(A) Based on appropriate literature and field study, identification of all threatened or endangered species listed under ORS 496.172(2), 564.105(2) or 16 USC 1533 that may be affected by the proposed facility. In compliance with OAR 345-021-0010(1)(q)(A), PacifiCorp identified all T&E species listed under Oregon Revised Statutes (ORS) 496.172(2) (state threatened and endangered wildlife species) and ORS 564.105(2) (state threatened and endangered plant species) that may be affected by the Project. 3.1 Desktop Review Existing data were utilized to determine the preliminary list of T&E species that could potentially occur within the Analysis Area. Review included the following databases and published literature: • Oregon Biodiversity Information Center (ORBIC) data request (ORBIC 2017); • Oregon Department of Agriculture (ODA) T&E Plant List (ODA 2017); • Oregon Department of Fish and Wildlife (ODFW) T&E Fish and Wildlife List (ODFW 2017); • The Environmental Assessment for the Project (BLM 2016); • The Biological Assessment for the Project (Attachment P-2); • The Biological Opinion for the Project (USFWS 2016); • Recovery Plans (USFWS 2011 and USFWS 2012); and Sams Valley Reinforcement Projects 2 Request for Amendment to Site Certificate EXHIBIT Q: THREATENED AND ENDANGERED SPECIES • StreamNet (2012). In order to identify T&E species with the potential to occur within the Analysis Area, known occurrence locations from ORBIC from within 5 miles of the Analysis Area were queried, as well as an additional request for occurrence locations outside of the Analysis Area in order to ensure all species with the potential to occur within the Analysis Area were included in this analysis, not just species that are known to occur within the Analysis Area. 3.1.1 Wildlife and Fish Wildlife species other than fish were considered potentially present if there was a known occurrence within 5 miles of the Analysis Area, or if their range and suitable habitat overlapped this area. No T&E fish species have the potential to occur, as no T&E fish-bearing streams are within the Analysis Area (StreamNet 2012, USFWS 2012). Some T&E fish and wildlife species listed in Josephine and Jackson counties in the Project’s Environmental Assessment (BLM 2016) were considered, but not carried forward into consideration in this exhibit (due to the Analysis Area being outside of their range, or lack of suitable habitat within the Analysis Area) include the marbled murrelet (Brachyramphus marmoratus; USFWS 2016), Lost River sucker (Deltistes luxatus; USFWS 2012), and short-nose sucker (Chasmistes brevirostris; USFWS 2012). The only T&E fish and wildlife species that potentially occurs within the Analysis Area and may have suitable habitat present is the northern spotted owl (Strix

The information presented in this synthesis concerns thematerial,social and religious aspects of aboriginal life as practiced by the Takelma of the Rogue River Valley, and their culturally akin Athapascan- neighbors,the Da-ku-be-te-de (Applegate River group) and the Tal-tuc-tun-te-da (Galice Creekgroup). The ethnographic material is representative of the time period immediately prior to the subjugation of these NativeAmericans,and their subsequent removal from southwestern Oregon in the 1850s; however,this synthesis has applications to a much greater time period in regional prehistory. Significant newinformation,extracted from the field notes of J. P. Harrington, Melville Jacobs and P. E. Goddard, adds to what has already been published concerning the lifeways of these Native American cultures,as well as clarifying territorial boundary questions in the region.

  • Geology of the Districts
    GEOLOGY OF THE DISTRICTS The Hilt and Colestin Fire Districts are located south of the jagged crest of the Siskiyou Mountains along the watershed divide between the Rogue and Klamath River drainages. The district boundaries lie within the Klamath Mountain geologic province and are largely drained by the main and east forks of Cottonwood Creek and their tributaries. The Klamath Mountains are steep, rugged mountains consisting mainly of metamorphic and igneous rocks that formed beneath the ocean and subsequently collided with the North American continent about 150 million years ago. Complexly folded and faulted rocks are bounded by belts of sparsely vegetated bands of serpentine. Rocks, including igneous, metamorphic, and sedimentary types, are very diverse and interspersed. The Klamath Mountains were formed, in part, by the rotation and westward movement of what was once the northern Sierra Nevada Mountains. Other rock types, including limestone and serpentine, formed under the ocean floor, were uplifted, and attached to the continent. Still other rocks (granites) formed from the melting and subsequent uplift caused by the sinking of the Pacific plate under the North American plate. The Klamath Mountains are irregular and do not form well defined ranges. Most of the short ranges which do occur in the Klamath Mountains run east-west, an unusual characteristic for mountains in North America. The northern portion of the Klamath range is known as the Siskiyou Mountains They extend in an east-west arc for approximately 100 mi (160 km) from east of Crescent City, California northeast along the north side of the Klamath River into Josephine and Jackson counties in Oregon.

    AMERICAN PENSTEMON SOCIETY NEWSLETTER Volume No. 5, Issue No. 3 apsdev.org September, 2011 Oregon’s Siskiyou Mountains, site of the 2011 American Penstemon Society Annual Meeting and Field Trips. By Julie Shapiro CONTENTS FOR THIS ISSUE This issue of the newsletter finds us all at the end of summer, indeed, at the autumnal equinox. I hope we are all enjoying the fruits of our labors in the garden, whether edible, visual or aesthetic. We finally get reports of the annual meeting and field trips. Those of us that missed this year’s adventures will have to read about it twice. There are reports for APS programs, changes, new and old members and notices of loss. The APS 2011 Photo Contest is announced and we even see the word floriferous used in a sentence! PENSTEMONS AND THEIR PHOTOS FROM THE SISKIYOUS, 2011 Article and photos by Ginny Maffitt Despite the late-to-leave, but welcome, snow pack in the Siskiyou Mts. this year, the attendees of the 2011 Annual Meeting (66-the most in years!) found a nice collection of penstemons blooming away. One of the two trips began south of Ashland along the entry road to Mt. Ashland ski area. Only 2 miles up the road, we stopped for a double treat of P. speciosus and P. deustus var. Illinois National Wild & Scenic River By Jack Myrick suffrutescens nearby. P. speciosus (Subgenus Habroanthus) isn’t usually found at this elevation (about 4000’) but is fairly common in east-side WA, OR, CA and ID. The guides had scouted for it lower down at the California border town of Hilt, but the plants were bloomed out.
