Coastal zone wind energy. Part I. Potential wind power density fields based on 3-D model simulations of the dominant wind regimes for three east and Gulf coast areas

Description: The results of applying a numerical model of the atmosphere to the problem of locating areas of maximum wind power are presented. Three US coastal regions, of approximately 10/sup 5/ km/sup 2/ area each, are investigated. For each region the spatial distribution of daily average power density (W m/sup -2/) for the lowest 100 m of the atmosphere is given for the three most prevalent weather regimes. These distributions are then combined to form an estimate of the annual average power density for each region. Comparisons with long-term climatological data at stations within each region show good agreement between model estimated and observed wind power density for two of the three regions studied.

Probablilistic evaluation of earthquake detection and location capability for Illinois, Indiana, Kentucky, Ohio, and West Virginia

Description: Probabilistic estimations of earthquake detection and location capabilities for the states of Illinois, Indiana, Kentucky, Ohio and West Virginia are presented in this document. The algorithm used in these epicentrality and minimum-magnitude estimations is a version of the program NETWORTH by Wirth, Blandford, and Husted (DARPA Order No. 2551, 1978) which was modified for local array evaluation at the University of Michigan Seismological Observatory. Estimations of earthquake detection capability for the years 1970 and 1980 are presented in four regional minimum m/sub b/ magnitude contour maps. Regional 90% confidence error ellipsoids are included for m/sub b/ magnitude events from 2.0 through 5.0 at 0.5 m/sub b/ unit increments. The close agreement between these predicted epicentral 90% confidence estimates and the calculated error ellipses associated with actual earthquakes within the studied region suggest that these error determinations can be used to estimate the reliability of epicenter location. 8 refs., 14 figs., 2 tabs.

Description of interview data regarding Pittsburgh and confluence toxic chemical accidents

Description: Evacuation is the protective action most often recommended in response to chemical releases in the United States. The appropriateness of a decision to evacuate depends on whether the affected areas can be cleared of residents before it is contaminated by the chemical release. In determining whether an evacuation can be completed in time, emergency officials must consider both technical and behavioral aspects. The technical components can be readily conceived and quantified. In contrast, the behavioral components are much more abstract and more difficult to estimate. This report summarizes the univariate analysis of responses to surveys conducted in two communities where evacuation was recommended following train derailments involving hazardous chemicals. The surveys were designed to identify the actions taken by residents upon receiving the emergency warning; determine when people received the warning, decided to take action, and implemented the action; and ascertain factors that might explain the nature and timing of their actions. The surveys were conducted in the Bloomfield section of Pittsburgh, Pennsylvania, and in the town of Confluence, Pennsylvania. The study confirms that compliance with an emergency warning to evacuate varies and that potentially dangerous delays can be expected. Significant differences were noted, however, in the rate and speed of compliance in the two communities. The surveys provide information on several factors that may be useful in determining the reasons for differences in the responses from the two communities as well as differences among individual respondents. Such factors include the time of day when the accident occurred, where the respondent was at the time, whether the family was together, previous disaster experience, pet ownership, the content of the warning message, and demographic characteristics. 4 refs., 4 figs., 18 tabs.

Ecological survey of M-Field, Edgewood Area Aberdeen Proving Ground, Maryland

Description: An ecological survey was conducted on M-Field, at the Edgewood Area, Aberdeen Proving Ground, Maryland. M-Field is used routinely to test army smokes and obscurants, including brass flakes, carbon fibers, and fog oils. The field has been used for testing purposes for the past 40 years, but little documented history is available. Under current environmental regulations, the test field must be assessed periodically to document the presence or potential use of the area by threatened and endangered species. The M-Field area is approximately 370 acres and is part of the US Army's Edgewood Area at Aberdeen Proving Ground in Harford County, Maryland. The grass-covered field is primarily lowlands with elevations from about 1.0 to 8 m above sea level, and several buildings and structures are present on the field. The ecological assessment of M-Field was conducted in three stages, beginning with a preliminary site visit in May to assess sampling requirements. Two field site visits were made June 3--7, and August 12--15, 1991, to identify the biota existing on the site. Data were gathered on vegetation, small mammals, invertebrates, birds, large mammals, amphibians, and reptiles.

Erosion control on a steeply sloped pipeline right-of-way in southwestern Pennsylvania

Description: The results of precipitation on steeply sloped pipeline rights-of-way (ROWs) during the time between ROW rehabilitation and the establishment of a dense, self-sustaining vegetative ground cover can cause locally severe soil erosion. This erosion results in elevated sediment loads in receiving streams and increases the difficulty and costs of ROW maintenance. A field study was completed that compared the environmental effectiveness of nine treatments on a 28% ROW slope in southwestern Pennsylvania. The six erosion-control methods investigated in the study, selected to represent a wide range in material type and installation cost, were (1) heavy application of straw mulch, (2) light application of straw mulch, (3) processed wood fiber, (4) chemical soil binder, (5) paper strips in netting, and (6) light straw mulch with a tacking agent. Each of the test plots also received the basic treatment of limestone, fertilizer, and a seed mixture commonly used to rehabilitate ROWs in the region. Precipitation, runoff volumes, and sediment yields were measured on each of 51 plots for 45 precipitation events during the 18-month study. Vegetation data were collected by the point-intercept method four times during the study to determine the amount of plant cover and species composition. Differences in sediment yield were observed among methods and between ROW location, but plant cover development was not influenced by erosion-control method or location. The relationship between environmental and cost data indicated that, of the six erosion-control methods tested, a light application of straw mulch was the most effective erosion-control treatment. 19 refs., 2 figs., 6 tabs.

Preliminary assessment of risk from toxic materials that might be mobilized in the decommissioning of Aberdeen Proving Ground Building E5032

Description: Aberdeen Proving Ground Building E5032 is scheduled for decommissioning, that is, for demolition. Because the building was formerly used for small-scale operations with incendiary and toxic chemical agents, it presents unusual concerns for occupational and public health safety during the demolition. For this reason, an anticipatory risk assessment was conducted, taking into consideration the building's history, properties of potential residual contaminants (particularly chemical and incendiary agents), and assumptions relating to meteorological conditions and envisioned modes of demolition. Safe maximum levels in concrete floors for the worst case were estimated to be: white phosphorus, 3200 mg/kg; mustard, 94 mg/kg; nerve agent GA (tabun), 6 mg/kg; cyanide, 500 mg/kg; and sulfide, 1400 mg/kg. These values will serve as planning guidance for the activities to follow. It is emphasized that the estimates must be reviewed, and perhaps revised, after sampling and analysis are completed, the demolition methodology is chosen, and dust emissions are measured under operating conditions.

Data base for the analysis of compositional characteristics of coal seams and macerals. Part 7. Petrographic variation due to depositional setting of the lower Kittanning seam, western Pennsylvania. Final report

Description: Detailed megascopic and microscopic petrographic analyses were conducted on samples of the Lower Kittanning seam from western Pennsylvania. Relationships were sought between the paleoenvironmental setting of the coal swamp and the vertical and lateral variability of lithotypes, maceral composition and vitrinite types. Megascopically, the four samples collected from the freshwater facies of the seam are similar in appearance and relative lithotype composition, and display no distinct vertical zonations. The sample from the marine-influenced central portion of the basin (PSOC-1340) possesses a marked vertical zonation into a bright lower zone and a dull upper zone. The lower zone is similar in appearance to the freswater samples. Detailed microscopic analyses revealed that the vertical zonation of PSOC-1340 is apparent in both the maceral and vitrinite type composition. No similar zonation is apparent in the microscopic analysis of the four freshwater facies samples. Similarities between the lower zone of PSOC-1340 and the whole seam of the freshwater samples are most apparent in the vitrinite-type analysis. The lower zone of PSOC-1340 and the whole seam from the freshwater facies are considered to be laterally equivalent coal types. The dull upper zone of PSOC-1340 is considered to have formed in response to a major change in the paleoenvironment of the swamp, probably a marine transgression. 49 references, 25 figures, 15 tables.

Recovery Efficiency Test Project: Phase 1, Activity report

Description: The recovery Efficiency Test well project addressed a number of technical issues. The primary objective was to determine the increased efficiency gas recovery of a long horizontal wellbore over that of a vertical wellbore and, more specifically, what improvements can be expected from inducing multiple hydraulic fractures from such a wellbore. BDM corporation located, planned, and drilled a long radius turn horizontal well in the Devonian shale Lower Huron section in Wayne County, West Virginia, demonstrating that state-of-the-art technology is capable of drilling such wells. BDM successfully tested drilling, coring, and logging in a horizontal well using air as the circulating medium; conducted reservoir modeling studies to protect flow rates and reserves in advance of drilling operations; observed two phase flow conditions in the wellbore not observed previously; cored a fracture zone which produced gas; observed that fractures in the core and the wellbore were not systematically spaced (varied from 5 to 68 feet in different parts of the wellbore); observed that highest gas show rates reported by the mud logger corresponded to zone with lowest fracture spacing (five feet) or high fracture frequency. Four and one-half inch casting was successfully installed in the borehole and was equipped to isolate the horizontal section into eight (8) zones for future testing and stimulation operations. 6 refs., 48 figs., 10 tabs.

Reports on investigations of uranium anomalies. National Uranium Resource Evaluation

Description: During the National Uranium Resource Evaluation (NURE) program, conducted for the US Department of Energy (DOE) by Bendix Field Engineering Corporation (BFEC), radiometric and geochemical surveys and geologic investigations detected anomalies indicative of possible uranium enrichment. Data from the Aerial Radiometric and Magnetic Survey (ARMS) and the Hydrogeochemical and Stream-Sediment Reconnaissance (HSSR), both of which were conducted on a national scale, yielded numerous anomalies that may signal areas favorable for the occurrence of uranium deposits. Results from geologic evaluations of individual 1/sup 0/ x 2/sup 0/ quadrangles for the NURE program also yielded anomalies, which could not be adequately checked during scheduled field work. Included in this volume are individual reports of field investigations for the following six areas which were shown on the basis of ARMS, HSSR, and (or) geologic data to be anomalous: (1) Hylas zone and northern Richmond basin, Virginia; (2) Sischu Creek area, Alaska; (3) Goodman-Dunbar area, Wisconsin; (4) McCaslin syncline, Wisconsin; (5) Mt. Withington Cauldron, Socorro County, New Mexico; (6) Lake Tecopa, Inyo County, California. Field checks were conducted in each case to verify an indicated anomalous condition and to determine the nature of materials causing the anomaly. The ultimate objective of work is to determine whether favorable conditions exist for the occurrence of uranium deposits in areas that either had not been previously evaluated or were evaluated before data from recent surveys were available. Most field checks were of short duration (2 to 5 days). The work was done by various investigators using different procedures, which accounts for variations in format in their reports. All papers have been abstracted and indexed.

Radiological survey of the former Aeroprojects Facility, West Chester, Pennsylvania

Description: The former Aeroprojects, Incorporated, Facility is located at 200-T East Rosedale Avenue, West Chester, Pennsylvania. The facility was under contract to the Atomic Energy Commission (AEC) beginning in 1951 to investigate the use of ultrasonic energy in a variety of manufacturing procedures. An unknown quantity of alloys and compounds of aluminum, beryllium, mercury, thorium, and uranium were used on the site. In the mid-1960s, work for the AEC tapered off and Aeroprojects began doing R D under other government contracts. It is the policy of the US Department of Energy (DOE) to verify that radiological conditions at such sites or facilities comply with current DOE guidelines. Therefore, at the request of DOE, a radiological survey of this site was conducted in May 1988. The survey included a gamma scan of the interior of the building that had been used during the contract work and the area outdoors immediately adjacent to the building. The survey results show that all gamma exposure rates approximated typical background levels found in the southeastern Pennsylvania area and, furthermore, were well within the DOE guideline. However, recently discovered information suggests that small amounts of radioactive residuals may have been buried on site. The areas where these suspected burials would have occurred are included in areas planned to be remediated by the current owners. 5 refs., 1 fig.

Spectra over complex terrain in the surface layer

Description: For design and control of Wind Energy Conversion Systems (WECS), the spectral distribution of wind speeds over frequencies needs to be known as well as velocity variances. Velocity spectra and other velocity statistics are estimated over three types of complex terrain: on tops of hills or escarpments; on land a short distance downwind from a water body; and over rolling farm land. The most important characteristics of turbulence models over uniform terrain are summarized briefly. Theoretical aspects of spectral characteristics over complex terrain are discussed, followed by detailed observations over complex terrain and procedures for their estimation. A theory is presented for calculation of response of engineering systems to wind fluctuations. (LEW)

Rock Creek Carbon Dioxide Pilot Project. Annual report, July 1980-June 1981

Description: Although this pilot has yet to prove that an expanded carbon dioxide flood in the Rock Creek Big Injun reservoir would be economically feasible, the pilot has been technically successful in several aspects. First of all, the mechanical operation of the project has proceeded smoothly in comparison to similar projects in the industry. Through this work, much experience has been gained (both mechanically and in reservoir engineering) that may be helpful in future projects of this nature. Also, from the production response to carbon dioxide injection and the Shaffer OB-2 core analysis, the miscible carbon dioxide injection displacement mechanism is moving oil. The amount of oil to be recovered, the time required, and the amount and cost of carbon dioxide injection required to produce this oil will all have a very significant effect on the economics of this project. 3 figures.

Near-surface neotectonic deformation associated with seismicity in the northeastern United States

Description: For the Lancaster, PA seismic zone a multifaceted investigation revealed several manifestations of near-surface, neotectonic deformation. Remote sensing data together with surface geological and geophysical observations, and recent seismicity reveal that the neotectonic deformation is concentrated in a NS-trending fault zone some 50 km in length and 10--20 km in width. Anomalies associated with this zone include distinctive lineament and surface erosional patterns; geologically recent uplift evidenced by elevations of stream terraces along the Susquehanna River; and localized contemporary travertine deposits in streams down-drainage from the inferred active fault zone. In the Moodus seismic zone the frequency of tectonically-controlled lineaments was observed to increase in the Moodus quadrangle compared to adjacent areas and dominant lineament directions were observed that are perpendicular and parallel to the orientation of the maximum horizontal stress direction (N80-85E) recently determined from in-situ stress measurements in a 1.5 km-deep borehole in the seismic zone and from well-constrained earthquake focal mechanisms. 284 refs., 33 figs.

Economic and engineering analysis of a selected full-scale trommel screen operation

Description: The trommel screen located at the Baltimore County municipal solid waste processing plant operated by Teledyne National was evaluated for a 1-year period. This trommel is used to remove noncombustibles from refuse derived fuel (RDF) and thereby reduce ash content and increase heating value of the RDF. The trommel is 8 m in length, 3.7 m in diameter, has 32-mm holes, and can be operated at 6 to 12 rpm. Economic operating and maintenance data were collected for the period November 1980 through October 1981. Trommel performance was measured during October 1980 and January, May, and August 1981 in order to determine performance during the four seasons of the year. Test runs were conducted to evaluate screening performance as a function of feedrate and rotational speed. Physically the trommel can convey infeed rates as high as 46 Mg/h, but screening efficiency decreases with increased feedrates. An infeed range of 7 to 13 Mg/h is practical as this insures the greatest probability of meeting fuel specifications and achieving optimum economic contribution. While high screening efficiencies can be achieved at low feedrates, the value of the heating value increase may not always offset the trommel cost below a feedrate of 5 mg/h. Seasonal variations occurred in the feed to the trommel, for example as a consequence of the higher percentage of lawn and garden waste present in spring and summer. Seasonal variations were manifested in varying particle size, ash content, moisture content, organic content, and heating value. However, no obvious trend of trommel performance versus season of the year was observed.

Mathematical simulation of transport of sediment and kepone in the James River estuary

Description: The mathematical simulation of sediment and Kepone (a highly chlorinated pesticide) transport in the James River estuary was conducted by applying the sediment and contaminant transport model, FETRA, to an 85-km river reach between Bailey and Burwell Bays. The FETRA code is an unsteady, two-dimensional, finite model, utilizing the Galerkin weighted residual method. The model consists of three submodels coupled together to take into account sediment-contaminant interaction. the submodels are: (1) sediment transport model, (2) dissolved contaminant transport model, and (3) particulate contaminant (contaminants adsorbed by sediment) transport model. Transport of sediment and particulate contaminants is simulated for each sediment type or size fraction. The FETRA code was applied to simulate the migration of sediment and Kepone for three river discharges. Tidally influenced depth and velocity distributions in the study area were obtained by the unsteady, one-dimensional code, EXPLORE. These results were used by the two-dimensional code, FETRA, to obtain longitudinal distributions of sediment and Kepone. Hence, the results presented here are cross-sectionally averaged values changing with tidal flow. Comparison of computed results and field data for both sediment and Kepone concentrations indicates very good agreement, confirming the validity of the model. Mathematical simulation of Kepone transport under most probable flow conditions yields an estimate of 89.1 kg/yr of Kepone transported seaward from Burwell Bay. Of this 89.1 kg of total Kepone, 25.3% is carried by sediment, while 74.7% is in a dissolved phase.

A review of accelerated response actions available to the environmental restoration program: Selected case histories and associated issues. [CONTAINS GLOSSARY]

Description: Accelerated actions were developed by the Environmental Protection Agency (EPA) within the regulatory framework for initiating early cleanup action or accelerating ongoing cleanup action to abate, mitigate, or reduce risk to human health or the environment at a contaminated waste site. The purposes of this report are to review the regulatory frameworks available to initiate accelerated actions at sites on the National Priorities List (NPL) and to provide case histories of sites where accelerated actions have been implemented. The findings of this report are applicable to non-NPL waste sites also. Accelerated actions are of interest to the Department of Energy (DOE) for two primary reasons: they are methods available to demonstrate progress in environmental restoration at DOE waste sites, and a subset of accelerated actions, termed interim remedial actions, may be required in place of final actions to avoid violating National Environmental Policy Act (NEPA) guidelines during the development of DOE Office of Environmental Restoration and Waste Management's (DOE- EM's) Programmatic Environmental Impact Statement (PEIS). To provide the case histories, interviews with staff and reviews of compliance documents were conducted for sites in EPA Regions 3, 4, and 7. 12 refs., 1 fig.
