Resolving Reliability Issues for an Offshore Platform Code
A fixed steel offshore platform design specification based on reliability concepts has been developed which could become an alternate to the existing working stress code, American Petroleum...
Efficient Probabilistic Structural Analysis Using an Advanced Mean Value Method
An advanced mean-value (AMV) method for probabilistic structural analysis is presented. This method blends the conventional mean value method with the advanced structural reliability analysis...

At the Kesterson National Wildlife Refuge in the San Joaquin Valley of California, severe fish and wildlife problems (waterfowl mortality, embryonic deformities, and reproductive failures)...
Extent of Water Quality Effects of Dams?A National Viewpoint
An overview of phosphorus impacts on impoundments, a subset of the contents of the Dam Water Quality Report is presented. The U.S. Environmental Protection Agency (EPA) is the lead investigator...
Reservoir Safe Yield Evaluation Using Simulation
The safe yield available from surface water impoundments serving the City of Portsmouth, Virginia, was evaluated, and the sensitivity of the reservoir system to several factors was investigated....
Water Conservation and Floodplain Regulation at Barrett Dam?San Diego, CA
Barrett Dam is owned and operated by the City of San Diego, California. This paper describes the response of the dam to heavy storms that occurred in Southern California in 1980. Computer-generated...
Resolution of Conflicts in Superfund Site Cleanups
In this paper, we present the typical sequence of tasks involved in the cleanup of a Superfund site under current regulations and guidance. We then pinpoint the areas where conflicts arise...
Sport Fish Consumption Advisories in the Great Lakes Basin: Assessment of Policy to Protect Human Health
Fish consumption advisories for Great Lakes sport fish are based on U.S. Food and Drug Administration (FDA) or U.S. Environmental Protection Agency (EPA) tolerance or action levels for...
Rolling Incinerators
The Illinois Environmental Protection Agency (IEPA) is using a mobile incinerator to clean up a former oil and solvent storage/transfer operation which was badly contaminated. The benefits...
EPA: Siting Permanent Solutions
EPA's SITE (Superfund Innovative Technology Evaluation) program is entering its third year. It is designed to speed up hazardous waste treatment technology. The program helps...
Speaking of RISK
With sensitivity, common sense and preparation, an engineer can explain risk effectively and fairly without alienating the public. Risk communicators should use a standard set of terms...
Biological Treatment of Hazardous Wastes
Biological treatment�using nature's bacteria and fungi�sometimes costs as little as 10-20% as incineration. Wastes in any form�solid, aqueous and gaseous�can be treated biologically....
Injecting an Oxygen Fix
Seasonal dissolved oxygen deficiencies are an old problem in hydropower discharges from deep impoundments. At the Richard B. Russell Dam near Savannah, Georgia, an innovative solution...
CADD Adds Safety to the Ryan
Computer aided design and drafting (CADD) was used to plan safety improvements for the Dan Ryan Viaduct, a two mile expressway in Chicago. Some 17 accidents per day took place along the...
Dams and Earthquakes: A Shaky Relationship
The rarity of earthquake-related dam failure does not mean that it can't happen. A phased geologic assessment could prevent potential catastrophe by determining where and...
The Cause of the Johnstown Flood
The Johnstown flood occurred in 1889, when an earth and rock dam failed during a record rainfall in eastern Pennsylvania. The flood was one of the worst civil disasters in the U.S.; 2,200...
Current Issues in Asbestos Removal
Asbestos is responsible for more worker deaths than any other substance used in the construction industry. This fact has prompted major regulatory changes during the past fifteen years....
Accommodation of Trucks on the Highway
Safety in Design
This book contains the papers presented at the symposium on accommodation of trucks on highways held in Nashville, Tenn., May 11, 1988. The papers address highway factors that contribute...
Evaluation Procedures for Hydrologic Safety of Dams
Procedures are proposed for selecting the safety design flood for both new and existing dams. The procedures are based on a quantitative risk assessment in which the likelihood and consequences...
