GMA speaks up during EPA coal ash hearing
09/02/2010
As hearings continued through September 2010, the U.S. Environmental Protection Agency (EPA) seeks comments regarding the regulation of coal ash containment sites. The Geosynthetic Materials Association (GMA) was among the first in line to address the issue Aug. 30 at the initial hearing in Arlington, Va. Read more, including remarks from GMA Members. ID:

Gas Exploration: Encana Does It Right
08/30/2010
Encana Oil & Gas USA Inc. has installed its first gas exploration well in Luzerne County, Pennsylvania. And to ensure residents that security measures are taken to prevent a blowout (such as experienced in the Gulf of Mexico by a BP oil rig) the company is talking to residents about the design. In addition to fail-safe mechanisms on the well, safety measures include a geosynthetic liner on the well pad, automated controlled to reduce human presence need on site, and a secondary containment layer beneath the diesel tank. The company reports that nearly every system component has two or three containment measures. ID:

Next Climate Change and Geosynthetics Conference
08/27/2010
IGS-Thailand, the Asian Center for Soil Improvement and Geosynthetics (ACSIG), and the Southeast Asian Geotechnical Society (SEAGS), under the auspices of International Geosynthetics Society (IGS), are jointly organizing the International Symposium on Geotechnical and Geosynthetics Engineering: Challenges and Opportunities on Climate Change to be held 7-8 December 2010 in Bangkok, Thailand. This event is co-organized by the Thailand Geotechnical Society (TGS) and Suranaree University of Technology (SUT). The symposium will gather academics, practitioners, partners, and stakeholders to discuss emergency and urgent issues related to climate change as well as the innovative mitigation measures in the context of geotechnical and geosynthetics engineering.

CETCO's Remediation University
08/25/2010
CETCO Remediation Technologies' Remediation University is a free full-day seminar and lunch consisting of comprehensive educational curriculum designed to provide practical and useful guidance to environmental professionals. This first half of the day will cover all aspects related to the subaqueous capping and treatment of contaminated sediments, including the use of marine mattresses for simplified construction and protection in highly erosive conditions, eliminating the need for costly and thick sand caps. Case studies and analysis from top industry professionals will be included. Each attendee will be provided with a "Certificate of Professional Development". Note: Space is limited, so register soon.

Paper: Mobilization of Reinforcement Tension within Geosynthetic-Reinforced Soil Structures
08/24/2010
From Kuo-Hsin Yang, Jorge G. Zornberg and Richard J. Bathurst: This paper examines the mobilization of reinforcement tension within geosynthetic-reinforced soil (GRS) structures at working stress and at large soil strains. Fully-mobilized reinforcement tension is assumed in most current design methods for the internal stability of GRS structures. In these methods the mobilized reinforcement tensile load is assumed to be equal to mobilized horizontal soil forces
computed using active earth pressure theory. However, comparison with reinforcement tension loads measured in the field has shown that this approach is conservative (excessively safe) by as much as a factor of two. This observation has prompted the current study in which stress data obtained from a numerical study and two instrumented large-scale GRS retaining walls were used to examine the relationship between mobilized reinforcement tensile load and mobilized soil shear strength. The results show that the ratio of reinforcement tensile load and mobilized soil shear strength is not constant Only when the average mobilized soil shear strength exceeds 95%, is reinforcement tensile capacity mobilized significantly. Nevertheless, less than 30% of reinforcement strength is mobilized when the average mobilized soil shear strength reaches peak soil shear capacity. These results help explain why current design methods lead to computed reinforcement loads that are very high compared to measured loads under operational conditions. ID:

Mining Opponents Want Higher Bonds, Better Engineering
08/04/2010
Mining operations in New Zealand are underbonded, many are complaining. Opponents of mining activities are even citing the low bonding issues as evidence of poor enviornmental controls. One project that has been cited is the Newmont Waihi Gold's final bond on the Martha open pit mine. It was capped at $10 million. Watchdogs contend it should have been $100 million, and if it had been it would have had more stringent controls such as geosynthetic liners on the tailings dam. It only has clay. Any environmental damage to the site greater than $10 million will have to be paid for by New Zealand government agencies. ID:
