Rehabilitation of the CNW and ICG Railroads
The railroad industry is an indispensable part of the American economy. However, the railroad infrastructure was allowed to deteriorate to the extent of having 5. 4 billion in deferred...
Probabilistic Design of Gravity Foundations for Arctic Offshore Structures
The use of the probabilistic simulation technique to estimate the variability of the resistance and the ice load on arctic gravity structures is illustrated in order to assess the safety...
Structural Considerations for a Radwaste Facility
The structural engineer needs to consider several criteria when designing a radioactive-waste processing facility in order to properly balance the requirements of safety and economy. This...
Structural Retrofit for Nuclear Power Plants
Retrofitting of nuclear power plants is a major concern these days. Recent rulings of regulatory agencies have affected most of the generating plants in some way. The lessons learned from...
The 1984 novel
Finite Element Methods in Structural Safety Studies
The use of finite element methods in structural safety studies is discussed and recent work in the area is briefly reviewed. Formulation for a first-order stochastic finite element method...
Installation of Category I Caissons
Founding a proposed safety-related Category I structure of a nuclear power plant on rock socketed caissons necessitated using precision installation techniques. These techniques were chosen...
Assessing Seepage at Uncontrolled Hazardous Waste Sites
This paper presents a conceptual framework for estimating the concentration of organic contaminants in a groundwater plume over time. The basis of this framework is the application of...
Application of Displacement of Discontinuity Methods in Underground Mine Design
Displacement discontinuity methods for stress analysis, pioneered by Starfield and Crouch (see, for example, Starfield and Crouch, 1972; Crouch, 1976; and Crouch and Starfield, 1983),...
Noise Assessment, Measurement, and Mitigation, an OSHA View
A discussion is presented on the Occupational Safety and Health Administration (OSHA) 29 CFR 1910. 95 General Industry noise exposure standards and the 29 CFR 1926. 52 and 1926. 101 Construction...
Monitoring Saves a Site
A comparison is made of two supported excavations that were similarly designed and constructed. Both excavation support systems consisted of a soldier pile and lagging sheeting wall supported...
Methodology of Determining Acceptable Levels of Heavy Metal Contamination in Municipal Sewage Sludge Applied to Cropland
The potential public health risks associated with the agricultural utilization of municipal sewage sludge dictate the development of environmentally acceptable criteria for the disposal...
Characterization of Indoor Carbon Monoxide Levels Produced by the Automobile
Integrated air samples were obtained at seven small and six large service stations and two dealerships. These establishments were sampled during cold and warm weather operations for eight...
Indoor Air Quality Simulations with the Mass Balance Model
Recent studies relate energy conservation measures, specifically to reduction of the air exchange rate of residences, with potential adverse health effects due to human exposure to increased...
Apportionment of Costs for Multi-Party Cleanups
A rational model was developed for allocating remedial response costs among potentially responsible parties involved in clean up of abandoned waste sites. The model takes into consideration...
Emerging Environmental Clean-Up Responsibility
This paper is a summary of the structure of regulations requiring clean-up of sites when closed or sold, specifically the State of New Jersey's Environmental Cleanup Responsibility...
Field Scale Solidification/Stabilization of Hazardous Wastes
The selection of appropriate remedial action measures only takes place after a full evaluation of all feasible alternatives. An alternative to off site disposal is solidification/stabilization...
Quantifying the Exposure
Methods of categorizing and modeling of exposure will be presented. The use of modeling for the estimation of population exposure will also be examined and some errors inherent with such...
Arsenic Contamination of Private Potable Wells
The results of a series of water testing programs of private residential wells in Pepperell, Massachusetts showed that of 301 wells tested, approximately 12 percent exhibited arsenic levels...
Risks from Metals Emitted by Sludge Incinerators
The types of incinerators most commonly used in the United States are the multiple hearth and fluidized bed designs. Airborne contaminants from either method of sludge incineration may...
