Information presented is in compliance with the criteria in Appendix A of 10 CFR Part 100, as described below, and meets the format and content recommendations of Regulatory Guide 1.70, Revision 1 (Reference 39). Because the development of the seismic inputs for DCPP predates the issuance of 10 CFR Part 100, Appendix A, "Seismic and Geologic Siting Criteria for Nuclear Power Plants," the DCPP earthquakes are plant specific. To capture the historical progress of the geotechnical and seismological investigations associated with the DCPP site, information pertaining to the following three time periods is described herein: (1) Original Design Phase: investigations performed in support of the Preliminary Safety Analysis Report, prior to the issuance of the Unit 1 construction permit (1967), through the early stages of the construction of Unit 1 (1971). The Design Earthquake and Double Design Earthquake ground motions are associated with this phase. These earthquakes are similar to the regulatory ground motion level that the NRC subsequently developed in 10 CFR Part 100 Appendix A as the "Operating Basis Earthquake (OBE)" ground motion and the "Safe Shutdown Earthquake (SSE)" ground motion, respectively. (2) Hosgri Evaluation Phase: investigations performed in response to the identification of the offshore Hosgri fault zone (1971) through the issuance of the Unit 1 operating license (1984). The 1977 Hosgri Earthquake ground motions are associated with this phase. The Hosgri Evaluation Phase does not affect or change the investigations and conclusions of the Original Design Phase. (3) Long Term Seismic Program (LTSP) Evaluation Phase: investigations performed in response to the License Condition Item No. 2.C.(7) of the Unit 1 operating license (1984) through the removal of the License Condition (1991), including current on-going investigations. The 1991 L TSP ground motion is associated with this phase. The LTSP Evaluation Phase does not affect or change the investigations and conclusions of either the Original Design Phase or the Hosgri Evaluation Phase. Overview Locations of earthquake epicenters within 200 miles of the plant site, and faults and earthquake epicenters within 75 miles of the plant site for either magnitudes or intensities, respectively, are shown in Figures 2.5-2, 2.5-3, and 2.5-4 (through 1972). A geologic and tectonic map of the region surrounding the site is shown in Figure 2.5-5, 2.5-1 Revision 21 September 2013 DCPP UNITS 1 & 2 FSAR UPDATE and detailed information about site geology is presented in Figures 2.5-8 through 2.5-16. Geology and seismology are discussed in detail in Sections 2.5.2 through 2.5.5. Additional information on site geology is contained in References 1 and 2. Detailed supporting data pertaining to this section are presented in Appendices 2.5A, 2.5B, 2.5C, and 2.5D of Reference 27 in Section 2.3. Geologic and seismic information from investigations that responded to Nuclear Regulatory Commission (NRC) licensing review questions are presented Appendices 2.5E and 2.5F of the same reference. A brief synopsis of the information presented in Reference 27 (Section 2.3) is given below.

  • Upper Newport Bay Ecosystem Restoration Project
    Upper Newport Bay Ecosystem Restoration Project Frequently Asked Questions (FAQ) 1. Why is the project necessary? Upper Newport Bay is one of the last remaining coastal wetlands in southern California, and continues to play a significant role in providing critical habitat for a variety of migratory waterfowl, shorebirds and endangered species of birds and plants. Bay sedimentation has significantly increased in the last several decades due to rapid urbanization of the watershed. As a result, open water areas are disappearing in the bay, tidal circulation has diminished and shoaling is occurring within the Federal and local navigation channels and slips. Upstream efforts to control sediment inputs to the Upper Newport Bay Ecological Reserve and within-Bay dredging projects have not been completely effective. A primary objective of this project is to effect management of sediments deposited within the bay, with the objective of reducing the frequency of dredging projects while also enhancing habitat values within the upper bay and slowing the detrimental impacts of sediment accumulation on the fish and wildlife habitats. 2. What are the benefits of the project? The Upper Newport Bay restoration project will allow for a reduced frequency of maintenance dredging; improve or restore estuarine habitats; sustain a mix of open water, mudflat and marsh habitat; increase tidal circulation for water quality; reduce predator access to sensitive habitats; improve public use and recreational access; and improve educational opportunities. 3.

  • NOTES TWO RECENT RECORDS of the CLAPPER RAIL from the BALLONA WETLANDS, LOS ANGELES COUNTY, CALIFORNIA Daniel S
    NOTES TWO RECENT RECORDS OF THE CLAPPER RAIL FROM THE BALLONA WETLANDS, LOS ANGELES COUNTY, CALIFORNIA DANIEL S. COOPER, Cooper Ecological Monitoring, Inc., 5850 W. 3rd St., #167, Los Angeles, California 90036; [email protected] I report on two recent records of the Clapper Rail (Rallus longirostris) from the Ballona Wetlands at Playa del Rey in Los Angeles County, including the first well- documented report in in the county over 40 years, from a site where a population persisted into the 1950s. On 25 August 2008, two biological consultants (A. Gutierrez and R. Woodfield, with Merkel and Associates, San Diego) sampling fish in a tidal chan- nel at the Ballona Wetlands just south of Ballona Creek spotted a bird they suspected was a Clapper Rail. On 21 January 2010 Gutierrez wrote to me, “on August 25, 2008 a Light-footed Clapper Rail was observed foraging along the eastern waterline of a channel in the pickleweed of the Ballona Wetlands. The observation occurred at 11:30 A.M. on a clear day, with no wind, a temperature of 70 °F, and during a low tide of 3.2 ft mean lower low water. Although it was a low tide, the water level was fairly high due to the tide being subject to muting and lag from the presence of tide gates at the Ballona Wetland. The Clapper Rail walked the edge of the high waterline from south to north and then back to the south, weaving through the pickleweed. After approximately 5 minutes, the Clapper Rail flew to the west shore of the channel and proceeded out of sight into the dense pickleweed.” Fortunately, (using a cell phone) Woodfield took a photograph (Figure 1) showing an unmistakable image of a Clapper Rail.

  • 3.4 Biological Resources
    3.4 Biological Resources 3.4 BIOLOGICAL RESOURCES 3.4.1 Introduction This section evaluates the potential for implementation of the Proposed Project to have impacts on biological resources, including sensitive plants, animals, and habitats. The Notice of Preparation (NOP) (Appendix A) identified the potential for impacts associated to candidate, sensitive, or special status species (as defined in Section 3.4.6 below), sensitive natural communities, jurisdictional waters of the United States, wildlife corridors or other significant migratory pathway, and a potential to conflict with local policies and ordinances protecting biological resources. Data used to prepare this section were taken from the Orange County General Plan, the City of Lake Forest General Plan, Lake Forest Municipal Code, field observations, and other sources, referenced within this section, for background information. Full bibliographic references are noted in Section 3.4.12 (References). No comments with respect to biological resources were received during the NOP comment period. The Proposed Project includes a General Plan Amendment (GPA) and zone change for development of Sites 1 to 6 and creation of public facilities overlay on Site 7. 3.4.2 Environmental Setting Regional Characteristics The City of Lake Forest, with a population of approximately 77,700 as of January 2004, is an area of 16.6 square miles located in the heart of South Orange County and Saddleback Valley, between the coastal floodplain and the Santa Ana Mountains (see Figure 2-1, Regional Location). The western portion of the City is near sea level, while the northeastern portion reaches elevations of up to 1,500 feet.

Marschalek California Department of Fish and Game South Coast Region 4949 Viewridge Avenue San Diego, CA 92123 ABSTRACT Monitoring to document breeding success of California least terns (Sternula antillarum browni) continued in 2006, with observers at 31 nesting sites providing data. An estimated 7006-7293 California least tern breeding pairs established 8173 nests and produced 2571-3644 fledglings at 45 documented locations. The fledgling to breeding pair ratio was 0.35-0.52. Statewide, 12,698 eggs were reported, with a site average of 1.57 eggs per nest (St Dev = 0.257) and an average clutch size of 1.62 eggs (St Dev = 0.494) for Type 1 sites. Numbers of nesting least terns were not uniformly distributed across all sites. Camp Pendleton, Naval Base Coronado, Los Angeles Harbor and Batiquitos Lagoon represented 58% of the breeding pairs while Camp Pendleton, Los Angeles Harbor, Bolsa Chica Ecological Reserve, Batiquitos Lagoon Ecological Reserve and Venice Beach produced 68% of the fledglings.

  • June 14, 2018 RTC Meeting Handout for Item 22
    Agron Bioenergy 860 West Beach Street Watsonville CA 95076 Office 831 383 1300: Fax 831 786 8508 George Dondero Executive Director Santa Cruz County Regional Transportation Commission 1523 Pacific Ave Santa Cruz, CA 95060 6/7/2018 Dear Mr Dondero, We are writing to you to express our serious concern about the status of the short rail line from Santa Cruz to Watsonville. The rail line is out of service as the operator cannot afford to inspect nor repair it. Rail is essential to our business, so we urge you to support the Sant Cruz RTC in approving Progressive Rail as the new operator of the short line so normal rail service can resume. Agron Bioenergy owns a multi-million-dollar Biodiesel plant on West Beach street in the disadvantaged city of Watsonville. The plant processes waste animal fats into fuel. Agron’s business plan relies on moving large amounts of freight by rail; the Agron site was purchased with the ability to spot 6 railcars for offload in mind. The anticipated rail traffic by late Q3 is around 20 railcars of raw materials a week. Agron’s plant is one of the largest biodiesel plants in California, and as such it supports both the reductions in criteria emissions and the reduction in greenhouse gases that are central to California’s emissions strategy for community and environmental health. Agron will reduce the overall carbon dioxide emissions in California by over 10000 metric tons in 2019. Agron anticipates producing 12m gallons of fuel; to be sold Watsonville. The fuel sales will bring extensive tax revenue to the city.

The study seeks to determine whether there have been discernable changes in vegetation alliances (communities), spatially or in type, within a 110-acre Study Area from the early twentieth century to the present day and how the changes compare with other similar historical analyses in California. Historical farming and ranching uses of the area are researched, and two family case studies are presented as paradigms of potential changes to vegetation as well as the connectivity with the larger socioeconomic context of Italian immigration into California. Examination of the vegetation alliances over the course of the historical study period utilizes several types of historical imagery, including twentieth-century aerial photography, ground level photography and nineteenth-century maps.

  • California Rare & Endagered Birds
    California brown pelican Pelecanus occidentalis californicus State Endangered 1971 Fully Protected Federal Endangered 1970 General Habitat: The California brown pelican uses a variety of natural and human-created sites, including offshore islands and rocks, sand spits, sand bars, jetties, and piers, for daytime loafing and nocturnal roosting. Preferred nesting sites provide protection from mammalian predators and sufficient elevation to prevent flooding of nests. The pelican builds a nest of sticks on the ground, typically on islands or offshore rocks. Their nesting range extends from West Anacapa Island and Santa Barbara Island in Channel Islands National Park to Islas Los Coronados, immediately south of and offshore from San Diego, and Isla San Martín in Baja California Norte, Mexico. Description: The brown pelican is one of two species of pelican in North America; the other is the white pelican. The California brown pelican is a large, grayish-brown bird with a long, pouched bill. The adult has a white head and dark body, but immature birds are dark with a white belly. The brown pelican weighs up to eight pounds and may have a wingspan of seven feet. Brown pelicans dive from flight to capture surface-schooling marine fishes. Status: The California brown pelican currently nests on West Anacapa Island and Santa Barbara Island in Channel Islands National Park. West Anacapa Island is the largest breeding population of California. In Mexico, the pelicans nest on Islas Los Coronados and Isla San Martín. Historically, the brown pelican colony on Islas Los Coronados was as large as, or larger than, that of recent years on Anacapa Island.

Most marine conservation areas such as Upper Newport Bay Estuary: 1.20 square miles State Marine Conservation Area provide some opportunity for commer- Other: 0.04 square miles cial and/or recreational take (species and gear exceptions vary by loca- tion - see reverse). One goal for California’s MPAs was to strategically place them near each other to form an interconnected network that would help to preserve the flow of life between marine ecosystems. Within that network each MPA has unique goals and regulations, and non-consumptive activities, permitted scientific research, monitoring, and educational pursuits may be allowed. Why was this location chosen for a state marine conservation area? One of the goals for Upper Newport Bay State Marine Conservation Area is to protect the largest remaining estuary in Southern California, a mix of marshland, tidal flats, and eelgrass beds. A variety of marine fish species may be found in the estuary, including California halibut, spotted bay bass, and croaker, whose young use the eelgrass beds as a nursery area. Invertebrates such as medusa worms and jackknife clams bury themselves in the mud, where they filter plankton from the silty water.
