The 10-20-30 Plan and Persistent Poverty Counties
This report discusses the 10-20-30 plan of reallocating funds in rural development programs toward counties with systemic poverty levels defined as 20% of the population being at or below poverty level for 30 years. This report explains why targeting funds to persistent poverty counties might be of interest, how "persistent poverty" is defined and measured, and how different interpretations of the definition and different data source selections could yield different lists of counties identified as persistently poor. This report does not compare the 10-20-30 plan's advantages and disadvantages against other policy options, nor does it examine the range of programs or policy goals for which the 1020-30 plan might be an appropriate policy tool.

40 Years of Discovery
History is most interesting when seen through the eyes of those who lived it. In this 40th anniversary retrospective of bioscience research at Lawrence Livermore National Laboratory, we've asked 19 scientists to share their personal recollections about a major accomplishment in the program's history. We have not tried to create a comprehensive or seamless story. Rather, we've attempted to capture the perspectives of key individuals, each of whom worked on a research program that met significant milestones. We have focused particularly on programs and accomplishments that have shaped the current Biology and Biotechnology Research Program (BBRP). In addition, we have included a timeline of biosciences at LLNL, a history of the directorate that appeared in the Laboratory's magazine, ''Science & Technology Review'', in 2002, and a list of bioscience-related articles that have appeared over the years in ''Science & Technology Review and its predecessor, Energy & Technology Review''. The landscape of biological science today is stunningly different from 40 years ago. When LLNL bioscience began in 1963, we knew about the structure of DNA and that it was the carrier of genetic information. However, it would be another year before scientists would understand how DNA codes for the production of …

100 Area Columbia River sediment sampling
Forty-four sediment samples were collected from 28 locations in the Hanford Reach of the Columbia River to assess the presence of metals and man-made radionuclides in the near shore and shoreline settings of the Hanford Site. Three locations were sampled upriver of the Hanford Site plutonium production reactors. Twenty-two locations were sampled near the reactors. Three locations were sampled downstream of the reactors near the Hanford Townsite. Sediment was collected from depths of 0 to 6 in. and between 12 to 24 in. below the surface. Samples containing concentrations of metals exceeding the 95 % upper threshold limit values (DOE-RL 1993b) are considered contaminated. Contamination by arsenic, chromium, copper, lead, and zinc was found. Man-made radionuclides occur in all samples except four collected opposite the Hanford Townsite. Man-made radionuclide concentrations were generally less than 1 pCi/g.

236-Z canyon utilization study
The 236-Z canyon contains equipment for repurification of plutonium and recovery of plutonium from scrap material. To meet production requirements of Fast Flux Test Facility/Clinch River Breeder Reactor oxide with the existing plant, several new pieces of equipment will be needed in the future. More storage space and a better accountability system are needed to support this increased production. The available canyon space needs to be utilized to its fullest in order to accommodate the new equipment. The purpose of this document is to identify the new pieces of equipment, show how they fit into the flowsheet, and locate them in the canyon.

241-SY-101 mixer pump lifetime expectancy. Final report
The purpose of WHC-SD-WM-TI-726, Rev. 0 241-SY-101 Mixer Pump Lifetime Expectancy is to determine a best estimate of the mean lifetime of non-repairable (located in the waste) essential features of the hydrogen mitigation mixer pump presently installed in 101-SY. The estimated mean lifetime is 9.1 years. This report does not demonstrate operation of the entire pump assembly within the Tank Farm ``safety envelope``. It was recognized by the Defense Nuclear Facilities Safety Board (DNFSB) this test pump was not specifically designed for long term service in tank 101-SY. In June 95 the DNFSB visited Hanford and ask the question, ``how long will this test pump last and how will the essential features fail?`` During the 2 day meeting with the DNFSB it was discussed and defined within the meeting just exactly what essential features of the pump must operate. These essential features would allow the pump to operate for the purpose of extending the window for replacement. Operating with only essential features would definitely be outside the operating safety envelope and would require a waiver. There are three essential features: 1. The pump itself (i.e. the impeller and motor) must operate 2. Nozzles and discharges leg must remain unplugged 3. …

300 Area TEDF DOE order compliance applicability assessment
This report summarizes the results of an effort to determine applicability of Department of Energy Orders at the Hanford 300 Area Treated Effluent Disposal Facility (TEDF). This assessment placed each of the reviewed orders into one of three compliance categories: (A) order applicable at a facility specific level (20 identified); (B) order applicable at a policy level (11 identified); or (C) order not applicable (21 identified). The scope of the assessment from the DOE Order standpoint was the 52 Level 1 Orders of interest to the Defense Nuclear Facility Safety Board (DNFSB). Although the TEDF is a non-nuclear facility, this order basis was chosen as a Best Management Practice to be consistent with ongoing efforts across the Hanford Site. Three tables in the report summarize the DOE order applicability by the compliance categories, with a table for Level A, Level B, and Level C applicability. The attachment to the report documents the compliance applicability assessment for each individual DOE Order.

14CO2 INCORPORATION INTO THE NUCLEIC ACIDS OF SYNCHRONOUSLYGROWING CHLORELLA CELLS
A study of the incorporation of {sup 14}CO{sub 2} into cell components of synchronously growing Chlorella pyrenoidosa has shown that DNA is synthesized primarily during the latter stages of the cell cycle prior to cell division. RNA was synthesized at an approximately equal rate during each of the three phases of the cell growth studied. No major differences were noted in the incorporation of {sup 14}CO{sub 2} into the soluble cell components in these long-term incorporation studies.

2000 Savannah River Biological Surveys for Westinghouse Savannah River Company
The Academy of Natural Sciences of Philadelphia has been conducting biological and water quality studies of the Savannah River since 1951. These studies are designed to assess potential effects of Savannah River Site (SRS) contaminants and warm-water discharges on the general health of the river and its tributaries. The study design includes multiple biological groups spanning a broad range of ecological roles, both because no single group is the best indicator of every component of water quality and because there is wide-spread agreement that protecting the entire system is important.

The 2010 Oil Spill: Natural Resource Damage Assessment Under the Oil Pollution Act
The 2010 Deepwater Horizon oil spill leaked an estimated 4.1 million barrels of oil into the Gulf of Mexico, damaging the waters, shores, and marshes, and the fish and wildlife that live there. When resources in the public trust are harmed by contamination, federal, state, foreign, and tribal governments may seek compensation for damage to natural resources under certain laws. This is done in two steps: first, by assessing the harm; then, by determining how and what restoration will take place. Compensation for natural resource damage is intended to restore the natural resources to their condition before the damage and to compensate the public for the lost use of those resources. This report discusses legislation that provides a framework for assessing and mitigating the damage caused by such spills.
