  • Terr–14 Mule Deer
    TERR–14 MULE DEER 1.0 EXECUTIVE SUMMARY In 2001 and 2002, the literature review, a camera feasibility study, the Mammoth Pool migration study (observation study, boat survey, and remote camera study), and a hunter access study were completed. A map of known mule deer summer and winter ranges, migration corridors, and holding areas was created based on the literature review. The camera feasibility study was conducted in the fall of 2001 to test the remote camera system for the spring 2002 remote camera study. The cameras were successful at capturing photographs of 82 animals, including photographs of six deer, during this testing period. The Mammoth Pool migration study consisted of an observation study, boat survey, and remote camera study. The study focused on documenting key migration routes across the reservoir and relative use, identifying potential migration barriers, and documenting any deer mortality in the reservoir. The observation study consisted of two observers positioned with binoculars at two observation points on Mammoth Pool at dusk and dawn in order to observe migrating deer. There were no observations of deer using the dam road. Two observations of deer were made out of a total of 51 observation periods. One observation consisted of a single deer that swam from the Windy Point Boat Launch area to the Mammoth Pool Boat Launch area. The other observation was of one group of five adult deer approaching the reservoir near the observation point by the Mammoth Pool Boat Launch, but turning back up the hill. There was no sign of difficulty in the deer swimming or exiting the reservoir and no obvious disturbance to the deer that turned back.

GETTING OUT OF JAIL FREE: SENTENCE CREDIT FOR PERIODS OF MISTAKEN LIBERTY Gabriel J. Chin* "The criminal is to go free because the constable has blundered."' When an individual is convicted of a crime and sentenced to a term of imprisonment, it generally is assumed that the convicted person is taken into custody after sentencing as ordered by the court. Surprisingly, how- ever, ministerial officers of the criminal justice system sometimes improp- erly release convicted criminals from custody or fail to take them into custody after sentencing. If the error never comes to the attention of the government, no legal issue is raised, and the convicted person may simply remain at liberty. Sometimes, however, the erroneously released pris- oner raises the issue with the government, or the government discovers the error on its own. In such cases, the law must determine whether a convict should receive credit for the time erroneously at liberty.

Bose, Secretary Federal Energy Regulatory Commission 888 First Street, NE Washington, DC 20426 Re: Southern California Edison Company; Petition for Declaratory Order and Request for Expedited Consideration; Project Nos. 67-__, 120-__, 2085-__,2086-__, 2174-__, 2175-__ Dear Secretary Bose: As set forth in the enclosed Petition for Declaratory Order (“Petition”), Southern California Edison Company (“SCE”) respectfully requests the Federal Energy Regulatory Commission (“FERC” or “Commission”) to declare on an expedited basis that the California State Water Resources Control Board (“SWRCB”) has waived authority under Section 401 of the Clean Water Act1 (“CWA”) for failure to act on SCE’s requests for water quality certification (“WQC”) within the statutorily prescribed one-year time period for all six projects within the Big Creek Hydroelectric System (collectively referred to as the “Big Creek Projects”) that are pending for relicensing before the Commission. For purposes of this Petition, the Big Creek Projects consist of Big Creek Nos. 2A, 8, and Eastwood Hydroelectric Project (FERC No. 67); Big Creek No. 3 Hydroelectric Project (FERC No. 120); Mammoth Pool Hydroelectric Project (FERC No. 2085); Vermilion Valley Hydroelectric Project (FERC No. 2086); Portal Hydroelectric Project (FERC No. 2174); and Big Creek Nos. 1 and 2 Hydroelectric Project (FERC No. 2175).2 The Commission’s relicensing of the Big Creek Projects has been delayed for well over a decade—and in some instances for nearly 20 years—due in large measure to SWRCB’s consistent annual direction that SCE submit a withdrawal-and-resubmittal letter for the express purpose of attempting to provide SWRCB another year to act on SCE’s WQC requests.

  • Science Concept 5: Lunar Volcanism Provides a Window Into the Thermal and Compositional Evolution of the Moon
    Science Concept 5: Lunar Volcanism Provides a Window into the Thermal and Compositional Evolution of the Moon Science Concept 5: Lunar volcanism provides a window into the thermal and compositional evolution of the Moon Science Goals: a. Determine the origin and variability of lunar basalts. b. Determine the age of the youngest and oldest mare basalts. c. Determine the compositional range and extent of lunar pyroclastic deposits. d. Determine the flux of lunar volcanism and its evolution through space and time. INTRODUCTION Features of Lunar Volcanism The most prominent volcanic features on the lunar surface are the low albedo mare regions, which cover approximately 17% of the lunar surface (Fig. 5.1). Mare regions are generally considered to be made up of flood basalts, which are the product of highly voluminous basaltic volcanism. On the Moon, such flood basalts typically fill topographically-low impact basins up to 2000 m below the global mean elevation (Wilhelms, 1987). The mare regions are asymmetrically distributed on the lunar surface and cover about 33% of the nearside and only ~3% of the far-side (Wilhelms, 1987). Other volcanic surface features include pyroclastic deposits, domes, and rilles. These features occur on a much smaller scale than the mare flood basalts, but are no less important in understanding lunar volcanism and the internal evolution of the Moon. Table 5.1 outlines different types of volcanic features and their interpreted formational processes. TABLE 5.1 Lunar Volcanic Features Volcanic Feature Interpreted Process

  • Rec 16 Emergency Services Evaluation
    REC 16 EMERGENCY SERVICES EVALUATION 1.0 EXECUTIVE SUMMARY The emergency services evaluation study identifies and characterizes available emergency services and those emergency service providers that respond to emergencies in the Big Creek Basin. Emergency service responders were consulted and asked to provide detailed information regarding their capabilities and service areas. The capabilities of the emergency response providers within the Big Creek Basin are summarized in terms of manpower, equipment and response times. This report also summarizes available historical emergency response data within the Big Creek Basin, based on service area data provided by the response agencies and emergency service providers. While efforts were made to obtain five years of historical emergency response data from each service provider, data for many providers were not available. The study results discuss data from the Sierra National Forest, California Department of Forestry and Fire Protection, and Emergency Medical Service (EMS) responders in Fresno and Madera counties. Data was not available from the law enforcement agencies. Historical emergency responses were first evaluated by reviewing the service area response data to determine which responses were located within the Big Creek Basin. The results of this evaluation indicate that of the total responses in the service area, the actual percentage of responses attributable to incidents in the Big Creek Basin are 3% for the Forest Service, 22% for the California Department of Forestry–Fresno County, 2% for the California Department of Forestry-Madera County, and 7% for EMS providers in Fresno and Madera Counties combined. Response data was further evaluated by sorting the available responses by service provider and response type into seven geographical regions in the Big Creek Basin as follows: (1) Shaver Lake and nearby communities; (2) Huntington Lake and nearby communities; (3) community of Big Creek; (4) Balsam Meadow Forebay; (5) Florence Lake; (6) High Sierra Area along Kaiser Pass Road including Lake Thomas A.
