Recent Progress in Coal Ash Utilization and the Effect of Environmental Issues and Regulations
This paper summarizes for civil engineers several publications that help to specify and use coal combustion by-products in construction and other applications in a technically sound, commercially...

Regulatory and Environmental Issues of the Chisman Creek Superfund Site
This paper discusses the regulatory and environmental issues arising from the response to the Record of Decision (ROD) for the Chisman Creek Superfund Site in York County, Virginia. Field...

Residential Damage in an Area of Underground Coal Mining
In order to estimate the potential for future subsidence-related residential damage, a statistical analysis of past residential damage in the Boulder-Weld, Colorado, coal field was performed....

Highway Damage Due to Subsidence
In this study subsidence profiles over three longwall panels, which were mined beneath state highways in Southeastern Ohio, were obtained. Immediate and short term subsidences were recorded....

Subsidence Abatement Projects in Wyoming?An Overview
Abatement projects were undertaken to prevent or minimize further subsidence in Wyoming communities. The paper gives a brief historical background on the mining activity in Wyoming. Subsidence...

Subsidence Control by High Volume Grouting
Mine grouting programs generally fall into two general methods: flushing and grout columns. With the flushing method, the entire mine under the area to be protected is filled. Grout columns...

Coal Mine Subsidence and Structures
Underground coal mining has occurred beneath 32 multiplied by 10**9m**2 (8 million acres) of land in the United States and will eventually extend beneath 162 multiplied by 10**9m**2 (40...

Advanced Reconstruction for Subsidence-Damaged Homes
To address many of the residential damage-reconstruction problems from mine subsidence a research and development project was undertaken in Illinois. Phase I of this project is complete...

Mining Subsidence Effects on Transportation Facilities
This paper presents case history information about mining subsidence effects on transportation facilities, including bridges, pavements, and culverts. Most of the field observations pertain...

Review of Subsidence and Stabilization Techniques
Currently, in Britain, the mining industry is undergoing a state of decline for economic reasons. Consequently, the number of old coal sites available for development schemes has increased....

Sewer Rehabilitation?Metro Chicago
After a number of public hearings in the late 1960's and early 1970's which focused on sewer backup problems in the Sanitary District's separate...

Trends and Emerging Issues: A Longitudinal Study of Government Agencies' Perceptions of Great Lakes Water Resources and Related Issues
The perceptions of government agencies with jurisdiction over Great Lakes' shoreline has changed over time with respect to important issues related to water quality and a...

Leachate Flow Through Landfills
The problem of estimating the amount of leachate generated in a landfill site is of significance in the assessment of potential environmental impacts. Although there are a variety of regulations...

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...

Small Diameter Gravity and Pressure Sewers
In communities with low population density or physical features that make conventional gravity sewers inordinately expensive, alternative sewer technologies can be significantly lower...

Lessons to be Learned from Lafayette Tennessee's Small Diameter Sewer System
Lafayette, Tennessee's septic tank effluent, small diameter gravity sewer (SDGS) system is believed to have been the first such project to be funded by the United States Environmental...

Foam Over Troubled Toxics
Foams are now being used to control noxious vapor emissions from hazardous waste landfills. Another use of foams is in control of vapors emitted by chemical spills and fires. This article...

Take Back the Land
Municipal sludge applied to land devastated by strip mining has brought thousands of acres of Ohio, Illinois and Pennsylvania land back to life. After two years of testing at a Palmerton,...

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...
