Slump dominated upper slope reservoir facies, Intra Qua Iboe (Pliocene), Edop Field, offshore Nigeria  

SciTech Connect

An integration of sedimentologic and 3D seismic data provides a basis for unraveling complex depositional processes and sand distribution of the Intra Qua Iboe (IQI) reservoir (Pliocene), Edop Field, offshore Nigeria. Nearly 3,000 feet of conventional core was examined in interpreting slump/slide/debris flow, bottom current, turbidity current, pelagic/hemipelagic, wave and tide dominated facies. The IQI was deposited on an upper slope in close proximity to the shelf edge. Through time, as the shelf edge migrated seaward, deposition began with a turbidite channel dominated slope system (IQI 1 and 2) and progressed through a slump/debris flow dominated slope system (IQI 3, the principal reservoir) to a tide and wave dominated, collapsed shelf-edge deltaic system (IQI 4). Using seismic time slices and corresponding depositional facies in the core, a sandy {open_quotes}fairway{open_quotes} has been delineated in the IQI 3. Because of differences in stacking patterns of sandy and muddy slump intervals, seismic facies show: (1) both sheet-like and mounded external forms (geometries), and (2) parallel/continuous as well as chaotic/hummocky internal reflections. In wireline logs, slump facies exhibits blocky, coarsening-up, fining-up, and serrated motifs. In the absence of conventional core, slump facies may be misinterpreted and even miscorrelated because seismic facies and log motifs of slumps and debris flows tend to mimic properties of turbidite fan deposits. The slump dominated reservoir facies is composed of unconsolidated fine-grained sand. Thickness of individual units varies from 1 to 34 feet, but amalgamated intervals reach a thickness of up to 70 feet and apparently form connected sand bodies. Porosity commonly ranges from 20 to 35%. Horizontal permeability commonly ranges from 1,000 to 3,000 md.

Reservoir compartmentalization of deep-water Intra Qua Iboe sand (Pliocene), Edop field, offshore Nigeria  

SciTech Connect

An integration of 3-D seismic and sedimentological information provides a basis for recognizing and mapping individual flow units within the Intra Qua Iboe (IQI) reservoir (Pliocene), Edop Field, offshore Nigeria. Core examination show the following depositional facies: A-Sandy slump/mass flow, B-Muddy slump/mass flow, C. Bottom current reworking. D-Non-channelized turbidity currents, E. Channelized (coalesced) turbidity currents. F-Channelized (isolated) turbidity currents, G-Pelagic/hemipelagic, H-Levee, I-Reworked slope, J-Wave dominated, and K-Tide dominated facies. With the exception of facies J and K, all these facies are of deep-water affinity. The IQI was deposited on an upper slope environment in close proximity to the shelf edge. Through time, as the shelf edge migrated scaward, deposition began with a channel dominated deep-water system (IQI 1 and 2) and progressed through a slump/debris flow dominated deep-water system (IQI 3, the principle reservoir) to a tide and wave dominated shallow-water system (IQI 4). Compositional and textural similarities between the deep-water facies result in similar log motifs. Furthermore, these depositional facies are not readily apparent as distinct seismic facies. Deep-water facies A, D, E, and F are reservoir facies, whereas facies B, C, G, H, and I are non-reservoir facies. However, Facies G is useful as a seismically mappable event throughout the study area. Mapping of these non-reservoir events provides the framework for understanding gross reservoir architecture. This study has resulted in seven defined reservoir units within the IQI, which serves as the architectural framework for ongoing reservoir characterization.

Inefficient subsidy in Nigerian oil sector; implications for revenue generation and household welfare in Nigeria  

Science Journals Connector (OSTI)

Subsidy exists when consumers are assisted by the government to pay less than the prevailing market price of a given commodity. In respect of fuel subsidy, it means that consumers would pay below the market price per litre of petroleum product. This paper is aim at analysing the effects of the increase in energy prices on the social welfare of Nigerian households and comparing the consequences with the condition in which in concurrence with increase in energy prices, the government undertakes transfer payments to Nigerian households in order to protect their social welfare status. An analytical reasoning model was adopted and within the framework of this model the effects of increase in energy price on social welfare is discussed. Decrease in energy subsidies and a shift towards market prices will result in a lower budget deficit for the government and powerfully harness one of the main causes of inflation. However, if the elimination of subsidies be accompanied by transfer payments to households, the result is increase in the government budget deficit which in its turn will enhance inflation thus very negatively affecting social welfare.

Polycyclic aromatic hydrocarbons in fresh and smoked fish samples from three Nigerian cities  

SciTech Connect

Nigeria is a major producer of crude oil in sub-Saharan Africa. In-shore and off-shore wells are located in richly watered creeks in the southern part of the country. Although published data on environmental impact assessment of the petroleum industry in Nigeria are lacking, there is a growing concern about the possible contamination of estuarine and coastal waters and of marine species by polycyclic aromatic hydrocarbon (PAHs). PAHs are ubiquitous priority pollutants that occur naturally in crude oil, automobile exhaust emissions and smoke condensates from incomplete combustion of carbonaceous materials. PAHs with high molecular weight are less readily biodegraded by indigenous microorganisms in some regions, and given their marked hydrophobic characteristics, may persist in the aqueous environment, thus contaminating the food chain by bioaccumulating in aquatic species like fish and mussels. Major Nigerian oil wells are located in the vicinity of breeding and harvesting sites serving the fresh-water fishing industry. Large hauls of fresh fish are normally consumed cooked in soups or smoke cured in handcrafted traditional ovens using freshly cut red mangrove (Rhizophora racemosa) wood as fuel. Though smoke curing is economical and may ensure longer conservation of fish, it undoubtedly increases the burden of PAHs in finished products as a result of partial charring and from smoke condensates or mangroves that also contain PAHs in measurable quantities as reported by Asita et al. (1991). Apart from PAHs analyzed by Emerole (1980) in smoked food samples from Ibadan using simple analytical methods, those from industrial and other anthropogenic sources have rarely been analyzed in Nigeria. We tried therefore to update the data and address this discrepancy. 14 refs., 4 figs., 2 tabs.

Domestic fuel price and the Nigerian macroeconomy  

Science Journals Connector (OSTI)

This study examined empirically a one-to-one nexus between domestic fuel price and various macroeconomic variables in Nigeria for the period spanning 1986 to 2011. The study adopted both a vector auto-regressive (VAR) and a vector error correction (VEC) models for appropriate analysis. For pairs of variables that are integrated of the same order but not co-integrated, the VAR model revealed that a unidirectional causation exist from domestic fuel price to short term interest rate while for the pair of variables that are integrated of the same order and are co-integrated the VEC model revealed the existence of causality from domestic fuel price to inflation rate in the long run and in the short run. The study recommended that serious caution should be taking by the government on domestic fuel price increase especially in an attempt to remove fuel subsidy and deregulate the downstream sector of the oil industry.

Effect of Water Quality on the Performance of Boiler in Nigerian Petroleum Industry  

E-Print Network (OSTI)

This work investigates quality of water used in boilers of Refinery Company in Nigeria. The results shows that the quality of water fed to boilers are off specification. Low water quality used in boilers led to frequent failure of the boilers as a result of tube rupture. This has resulted into low capacity utilization and loss of processing fees. The poor performance of the boiler feed treatment plant is attributable to the deplorable condition of water intake plant, raw water treatment, demineralization plant, change in raw water quality and non-functioning of the polisher unit.

The relationship between oil prices and the Nigerian stock market. An analysis based on fractional integration and cointegration  

Science Journals Connector (OSTI)

Abstract We examine the relationship between oil prices and the stock market in Nigeria. We focus on the degree of persistence of the series, and based on the similarities observed between the two series, a fractionally cointegrated framework is proposed. The results indicate that the two series display a similar order of integration, which is close to, although above 1. Testing for cointegration, this is decisively rejected since the order of integration in the equilibrium relationship was similar to that of the individual series. However, testing for long memory with oil prices acting as a weakly exogenous regressor, we obtained significant evidence of a positive relationship between the two variables though with a short memory effect, this relation being significant only during the following three months.

Use of Quantitative Uncertainty Analysis to Support M&VDecisions in ESPCs  

SciTech Connect

Measurement and Verification (M&V) is a critical elementof an Energy Savings Performance Contract (ESPC) - without M&V, thereisno way to confirm that the projected savings in an ESPC are in factbeing realized. For any given energy conservation measure in an ESPC,there are usually several M&V choices, which will vary in terms ofmeasurement uncertainty, cost, and technical feasibility. Typically,M&V decisions are made almost solely based on engineering judgmentand experience, with little, if any, quantitative uncertainty analysis(QUA). This paper describes the results of a pilot project initiated bythe Department of Energy s Federal Energy Management Program to explorethe use of Monte-Carlo simulation to assess savings uncertainty andthereby augment the M&V decision-making process in ESPCs. The intentwas to use QUA selectively in combination with heuristic knowledge, inorder to obtain quantitative estimates of the savings uncertainty withoutthe burden of a comprehensive "bottoms-up" QUA. This approach was used toanalyze the savings uncertainty in an ESPC for a large federal agency.The QUA was seamlessly integrated into the ESPC development process andthe incremental effort was relatively small with user-friendly tools thatare commercially available. As the case study illustrates, in some casesthe QUA simply confirms intuitive or qualitative information, while inother cases, it provides insight that suggests revisiting the M&Vplan. The case study also showed that M&V decisions should beinformed by the portfolio risk diversification. By providing quantitativeuncertainty information, QUA can effectively augment the M&Vdecision-making process as well as the overall ESPC financialanalysis.

Disability rights: the need for safeguard  

Science Journals Connector (OSTI)

Persons with disabilities have since suffered so much violation of their human rights due to various reasons one of which is the tardy response of the Nigerian federal legislature in enacting a disability law. These most vulnerable groups are currently exposed to frequent abuses from different quarters because of the absence of a specific legal framework to safeguard their human rights. The Nigerian constitution which is the only domestic law guaranteeing its citizens' fundamental rights is however limited in scope as it does not address disability rights specifically. Considering the above, this paper will take an in-depth look at the common forms of violations or barriers faced by disabled persons in the society and the grave effect of such violations. Practicable and concrete recommendations that will help safeguard the inherent dignity of these vulnerable groups will then be proffered.

Public budgeting, public policy, and the politics of resource allocation in Nigeria  

SciTech Connect

The problem of determining who gets what in terms of allocating the nation's resources has plagued Nigerian leaders since independence. It is in this context that this dissertation is focused on the politics of the federal governments's use of the budget as an effective mechanism for mobilizing and constructively utilizing the nation's human and material resources to improve the general well-being of all segments of the Nigerian society. This study was conducted through direct interviews and discussions with some federal government officials and some Nigerian scholars concerned about the problems of development in Nigeria. From the findings, it is concluded that the federal budget process has not functioned efficiently and effectively as a vehicle for moving the nation forward in the direction of sustained and balanced economic progress. Whereas the above situation can be attributed to some structural deficiencies in the budgetary process, it can also be argued that bribery and corruption, fraud and misuse of public funds by politicians and top government officials, be they civilians or military, have undermined all efforts at using the budget as an instrument for accomplishing development objectives.

EPR-Steering measure for two-mode continuous variable states  

E-Print Network (OSTI)

Steering is a manifestation of quantum correlations that embodies the Einstein-Podolsky-Rosen (EPR) paradox. While there have been recent attempts to quantify steering, continuous variable systems remained elusive. We introduce a steering measure for two-mode continuous variable systems that is valid for arbitrary states. The measure is based on the violation of an optimized variance test for the EPR paradox, and admits a computable and experimentally friendly lower bound only depending on the second moments of the state, which reduces to a recently proposed quantifier of steerability by Gaussian measurements. We further show that Gaussian states are extremal with respect to our measure, minimizing it among all continuous variable states with fixed second moments. As a byproduct of our analysis, we generalize and relate well-known EPR-steering criteria. Finally an operational interpretation is provided, as the proposed measure is shown to quantify the optimal guaranteed key rate in semi-device independent qua...

Summer 2003 Motor Gasoline Outlook.doc  

Gasoline and Diesel Fuel Update (EIA)

3 3 1 Short-Term Energy Outlook April 2003 Summer 2003 Motor Gasoline Outlook Summary For the upcoming summer season (April to September 2003), high crude oil costs and other factors are expected to yield average retail motor gasoline prices higher than those of last year. Current crude oil prices reflect a substantial uncertainty premium due to concerns about the current conflict in the Persian Gulf, lingering questions about whether Venezuelan oil production will recover to near pre-strike levels in time for the peak driving season, and the impact of recent disruptions in Nigerian oil output. Moreover, unusually low crude oil and gasoline inventory levels at the outset of the driving season are expected to keep prices high throughout much of the


Short-Term Energy Outlook  

Gasoline and Diesel Fuel Update (EIA)

3 3 1 Short-Term Energy Outlook April 2003 Overview World Oil Markets. Crude oil prices fell sharply at the onset of war in Iraq, but the initial declines probably overshot levels that we consider to be generally consistent with fundamental factors in the world oil market. Thus, while near-term price averages are likely to be below our previous projections, the baseline outlook for crude oil prices (while generally lower) is not drastically different and includes an average for spot West Texas Intermediate (WTI) that is close to $30 per barrel in 2003 (Figure 1). The mix of uncertainties related to key oil production areas has changed since last month, as Venezuelan production has accelerated beyond previous estimates while Nigerian output has been reduced due to internal conflict.


Incineration of hazardous wastes from the petroleum industry in Nigeria  

Science Journals Connector (OSTI)

Persistent hazardous wastes are produced in the recovery, processing and upgrading of crude petroleum in Nigeria. However, recent developments in environmental pollution control are drawing increasing attention to the problems of hazardous wastes. The ever-increasing need to control these wastes from the petroleum industry often compels the chemical engineer to specify methods of treatment and disposal. Present methods for disposal are becoming increasingly undesirable for a number of reasons, and incineration is being considered as an alternative. This paper reviews the extent of hazardous waste generation from the Nigerian petroleum industry and its environmental implications. It also examines the current disposal methods and the incineration technology option. The major chemical engineering concepts of the incineration process and the principles guiding their operations are discussed. The potential for the use of incineration is examined, as well as information that would aid the choice of incineration system for new applications.

The cost of carbon-dioxide abatement in Nigeria's energy sector  

Science Journals Connector (OSTI)

The cost of carbon dioxide abatement in Nigeria's energy sector has been estimated using MARKAL, a large-scale linear optimisation model, for the period between 1990 and the year 2030. The baseline scenario is based on the concept of the most-likely development-path in the energy system. An integrated abatement scenario is then developed by augmenting the baseline scenario with a set of abatement options: demand-side options, supply-side options, options for increased use of renewable resources, and options for increased use of the associated natural gas that is currently being flared in Nigerian oil fields. The options are assessed and ranked on the basis of their incremental costs per ton of carbon dioxide reduced. Finally, results of a sensitivity study of the model based on perturbations in energy demand growth assumptions are discussed.

Optimal structure of Nigeria's energy sector under carbon-dioxide reduction  

Science Journals Connector (OSTI)

Energy requirements in Nigeria will continue to increase as a result of an expanding economy and a rapidly growing population. Although the country has abundant natural energy resources, substantial financial commitments will be required to put the necessary supply infrastructure in place in order to meet the growing requirements. Furthermore, there is the need for a carefully planned consumption pattern in view of the growing awareness of the environmental problems posed by continued consumption of these resources. This paper discusses a study of the optimal structure of the Nigerian energy sector over a period of 40 years, based on the least-cost path and carbon-dioxide emission reduction. The emission reduction strategies take the form of linear annual reductions, reaching 20% and 40% respectively below the year 2030 baseline emissions. The effects of these constraints on fuel mix in the supply and demand structure of the energy system are presented.

CPO CPO Porphyrins have earned the title "pigments of life" (1) because they are essential for all life on planet earth. Porphyrins are the precursors of heme, chlorophyll, and cyanocobalamin (vitamin B12). Heme is an iron-coordinated porphyrin and serves as a prosthetic group in several proteins to mediate catalysis (cytochromes, peroxidases) or recognize diatomic molecules like oxygen (globins), carbon monoxide (CO) (cytochrome oxidase), and nitric oxide (NO) (soluble guanylyl cyclase) (2,3). With the exception of a few microorganisms, heme is found in all three archaea, prokarya, and eukarya kingdoms (2). On the one hand, heme biosynthesis is a sine qua non for the function of heme-containing enzymes and proteins. For example, gaseous messengers like NO cannot be biosynthesized in humans without the heme-containing enzyme nitric oxide synthase (4). On the other hand, enzymatic degradation of heme results in the generation of CO - a key cellular signal generated as a by product of heme oxygenase chemistry.


The role of electric cars in Amsterdam’s transport system in the year 2015; a scenario approach  

Science Journals Connector (OSTI)

Electric cars may contribute significantly to a reduction in external costs of urban transport. This paper investigates, using a scenario analysis, the necessary conditions for their possible introduction in the city of Amsterdam. First, a background sketch of recent developments in Amsterdam is given, followed by an outline of the potential of, and the problems inherent in, the introduction of electric cars. Four scenarios are constructed by means of the so-called Spider-model. It is visualized in a picture that consists of quadrants and eight axes on which important future developments are sketched on a five point scale. The quadrants represent policy concerns about national and international flanking policies, local economic developments, local spatial policies and public transport policies, respectively. The scenarios used are: ‘Prosperous Amsterdam’, ‘Sustainable Amsterdam’, ‘Pauperized Amsterdam’ and ‘Lonely Amsterdam’, which largely differ in economic developments and in the spatial focus on sustainability issues. These scenarios act as frameworks for the policy development centered around the future adaption of electric cars in the city. Finally, the transport system and the potential role of the electric car in each scenario is investigated. It is concluded that flanking policies at all levels of spatial aggregation, as well as economic development are a sine qua non for a successful introduction of the electric car.

Ecosystem-Atmosphere Exchange of Carbon, Water and Energy over a Mixed Deciduous Forest in the Midwest  

SciTech Connect

During the project period we continued to conduct long-term (multi-year) measurements, analysis, and modeling of energy and mass exchange in and over a deciduous forest in the Midwestern United States, to enhance the understanding of soil-vegetation-atmosphere exchange of carbon. At the time when this report was prepared, results from nine years of measurements (1998 - 2006) of above canopy CO2 and energy fluxes at the AmeriFlux site in the Morgan-Monroe State Forest, Indiana, USA (see Table 1), were available on the Fluxnet database, and the hourly CO2 fluxes for 2007 are presented here (see Figure 1). The annual sequestration of atmospheric carbon by the forest is determined to be between 240 and 420 g C m-2 a-1 for the first ten years. These estimates are based on eddy covariance measurements above the forest, with a gap-filling scheme based on soil temperature and photosynthetically active radiation. Data gaps result from missing data or measurements that were rejected in qua)lity control (e.g., during calm nights). Complementary measurements of ecological variables (i.e. inventory method), provided an alternative method to quantify net carbon uptake by the forest, partition carbon allocation in each ecosystem components, and reduce uncertainty on annual net ecosystem productivity (NEP). Biometric datasets are available on the Fluxnext database since 1998 (with the exclusion of 2006). Analysis for year 2007 is under completion.

Quantum Measurements: a modern view for quantum optics experimentalists  

E-Print Network (OSTI)

In these notes, based on lectures given as part of the Les Houches summer school on Quantum Optics and Nanophotonics in August, 2013, I have tried to give a brief survey of some important approaches and modern tendencies in quantum measurement. I wish it to be clear from the outset that I shy explicitly away from the "quantum measurement problem," and that the present treatment aims to elucidate the theory and practice of various ways in which measurements can, in light of quantum mechanics, be carried out; and various formalisms for describing them. While the treatment is by necessity largely theoretical, the emphasis is meant to be on an experimental "perspective" on measurement -- that is, to place the priority on the possibility of gaining information through some process, and then attempting to model that process mathematically and consider its ramifications, rather than stressing a particular mathematical definition as the {\\it sine qua non} of measurement. The textbook definition of measurement as being a particular set of mathematical operations carried out on particular sorts of operators has been so well drilled into us that many have the unfortunate tendency of saying "that experiment can't be described by projections onto the eigenstates of a Hermitian operator, so it is not really a measurement," when of course any practitioner of an experimental science such as physics should instead say "that experiment allowed us to measure something, and if the standard theory of measurement does not describe it, the standard theory of measurement is incomplete." Idealisations are important, but when the real world breaks the approximations made in the theory, it is the theory which must be fixed, and not the real world.

Closure Report for CAU No. 430: Buried Depleted Uraniuim Artillery Round No. 1, Tonopah Test Range, Revision 0  

SciTech Connect

1.1 Purpose This Closure Report presents the information obtained from investigative actions performed to justify the decision for clean closure of CAU 430 through "No Further Action." The investigative actions were performed per the Streamlined Approach for Environmental Restoration Plan, CA UNO. 430: Buried Depleted Uranium Artille~ Round No. 1, Tonopah Test Range (DOE/NV, 1996a) (hereafter referred to as the SAFER Plan). The Buried DU Artillery Round No. 1 is located approximately 1.1 kilometers (km) (0.7 mile [mi]) south of Avenue 13 in the test area south of Area 9 (Figure 1-2). The site was thought to consist of a potentially unexploded W-79 Joint Test Assembly (JTA) test artillery projectile with high explosives (HE) and DU. The DU was substituted for Special Nuclear Material to prevent a nuclear explosion and yet retain the physical characteristics of uranium for ballistic and other mechanical tests. The projectile was reportedly buried in one pit, approximately 5 to 10 feet (ft) deep (Smith, 1993; Smith, 1996; Quas, 1996). The exact location of the burial pit is unknown; however, three disturbed areas (Sites A, B, and C) were identified through geophysical surveys, site visits, and employee interviews as possible locations of the test projectile (Figure 1-3). Results of the investigation are summarized within this Closure Report. Additional information about the site and investigation activities may be found in the SAFER Plan (DOE/NV, 1996a). 1.2 Scope The objectives of the SAFER Plan (DOE/NV, 1996a) activities were to prepare the site for closure through locating and identi~ing the projectile (Buried DU Artillery Round No. 1), destroying the projectile and any remaining components, collecting soil samples to detect residual contamination resulting from projectile destruction, and finally, remediating residual contamination.




Bioinformatics in the information age  

SciTech Connect

There is a well-known story about the blind man examining the elephant: the part of the elephant examined determines his perception of the whole beast. Perhaps bioinformatics--the shotgun marriage between biology and mathematics, computer science, and engineering--is like an elephant that occupies a large chair in the scientific living room. Given the demand for and shortage of researchers with the computer skills to handle large volumes of biological data, where exactly does the bioinformatics elephant sit? There are probably many biologists who feel that a major product of this bioinformatics elephant is large piles of waste material. If you have tried to plow through Web sites and software packages in search of a specific tool for analyzing and collating large amounts of research data, you may well feel the same way. But there has been progress with major initiatives to develop more computing power, educate biologists about computers, increase funding, and set standards. For our purposes, bioinformatics is not simply a biologically inclined rehash of information theory (1) nor is it a hodgepodge of computer science techniques for building, updating, and accessing biological data. Rather bioinformatics incorporates both of these capabilities into a broad interdisciplinary science that involves both conceptual and practical tools for the understanding, generation, processing, and propagation of biological information. As such, bioinformatics is the sine qua non of 21st-century biology. Analyzing gene expression using cDNA microarrays immobilized on slides or other solid supports (gene chips) is set to revolutionize biology and medicine and, in so doing, generate vast quantities of data that have to be accurately interpreted (Fig. 1). As discussed at a meeting a few months ago (Microarray Algorithms and Statistical Analysis: Methods and Standards; Tahoe City, California; 9-12 November 1999), experiments with cDNA arrays must be subjected to quality control. Variables as simple as temperature and illumination differences across a microarray slide can alter readings. Between slides, additional variables add to the difficulty of comparison. For example, John Quackenbush (The Institute for Genomic Research) described the complexities associated with assuring quality control between microarray slides in a presentation both humorous and disquieting in which he demonstrated how air conditioning can affect sample readouts. Manfred Zorn (Lawrence Berkeley National Laboratory, LBNL), chair of a working group on standards, launched a preliminary effort to lay down definitions and standards for microarray analysis with particular emphasis on experimental design, measurement, and analysis documentation.

Final work plan : phase I investigation of potential contamination at the former CCC/USDA grain storage facility in Montgomery City, Missouri.  

SciTech Connect

From September 1949 until September 1966, the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) leased property at the southeastern end of Montgomery City, Missouri, for the operation of a grain storage facility. During this time, commercial grain fumigants containing carbon tetrachloride were commonly used by the CCC/USDA and the private grain storage industry to preserve grain in their facilities. In January 2000, carbon tetrachloride was detected in a soil sample (220 {micro}g/kg) and two soil gas samples (58 {micro}g/m{sup 3} and 550 {micro}g/m{sup 3}) collected at the former CCC/USDA facility, as a result of a pre-CERCLIS site screening investigation (SSI) performed by TN & Associates, Inc., on behalf of the U.S. Environmental Protection Agency (EPA), Region VII (MoDNR 2001). In June 2001, the Missouri Department of Natural Resources (MoDNR) conducted further sampling of the soils and groundwater at the former CCC/USDA facility as part of a preliminary assessment/site inspection (PA/SI). The MoDNR confirmed the presence of carbon tetrachloride (at a maximum identified concentration of 2,810 {micro}g/kg) and chloroform (maximum 82 {micro}g/kg) in the soils and also detected carbon tetrachloride and chloroform (42.2 {micro}g/L and 58.4 {micro}g/L, respectively) in a groundwater sample collected at the former facility (MoDNR 2001). The carbon tetrachloride levels identified in the soils and groundwater are above the default target level (DTL) values established by the MoDNR for this contaminant in soils of all types (79.6 {micro}g/kg) and in groundwater (5.0 {micro}g/L), as outlined in Missouri Risk-Based Corrective Action (MRBCA): Departmental Technical Guidance (MoDNR 2006a). The corresponding MRBCA DTL values for chloroform are 76.6 {micro}g/kg in soils of all types and 80 {micro}g/L in groundwater. Because the observed contamination at Montgomery City might be linked to the past use of carbon tetrachloride-based fumigants at its former grain storage facility, the CCC/USDA will conduct investigations to (1) characterize the source(s), extent, and factors controlling the possible subsurface distribution and movement of carbon tetrachloride at the Montgomery City site and (2) evaluate the health and environmental threats potentially represented by the contamination. This work will be performed in accord with the Intergovernmental Agreement established between the Farm Service Agency of the USDA and the MoDNR, to address carbon tetrachloride contamination potentially associated with a number of former CCC/USDA grain storage facilities in Missouri. The investigations at Montgomery City will be conducted on behalf of the CCC/USDA by the Environmental Science Division of Argonne National Laboratory. Argonne is a nonprofit, multidisciplinary research center operated by UChicago Argonne, LLC, for the U.S. Department of Energy (DOE). The CCC/USDA has entered into an agreement with DOE, under which Argonne provides technical assistance to the CCC/USDA with environmental site characterization and remediation at its former grain storage facilities. The site characterization at Montgomery City will take place in phases. This approach is recommended by the CCC/USDA and Argonne, so that information obtained and interpretations developed during each incremental stage of the investigation can be used most effectively to guide subsequent phases of the program. This site-specific Work Plan outlines the specific technical objectives and scope of work proposed for Phase I of the Montgomery City investigation. This Work Plan also includes the community relations plan to be followed throughout the CCC/USDA program at the Montgomery City site. Argonne is developing a Master Work Plan specific to operations in the state of Missouri. In the meantime, Argonne has issued a Provisional Master Work Plan (PMWP; Argonne 2007) that has been reviewed and approved by the MoDNR for current use. The PMWP (Argonne 2007) provides detailed information and guidance on the investigative technologies, analytical methodologies, qua
