Book Synopsis Evaluating Dust Suppressant Efficacy and Roadbed Stability of Dirt and Gravel Roads by : Andrew Eck

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fugitive dust emissions from dirt and gravel roads are the largest source of particulate matter less than ten microns (PM10) in the United States. This dust poses a threat to human and environmental health and is sometimes mitigated adding commercial dust suppression products to the road surface. Oil and gas produced waters (OGPW) can have similar chemistry to commercially available dust suppressant products and are an inexpensive or often free alternative for road managers. Pennsylvania and at least twelve other states have regulated OGPW for use as dirt and gravel road dust suppressants. Previous studies demonstrated that elevated concentrations of total dissolved salts (TDS) is predictive of better performing dust suppressant. However OGPW with high sodium content have been shown to increase fine material dispersion, which can drastically reduce dust suppression efficacy. This study evaluated dust suppression efficacy and roadbed stability of twelve OGPW, five commercial hygroscopic products (calcium and magnesium chloride salts), and five commercial organic products. Dust suppression efficacy was tested with an aerosol monitor by tumbling treated disks of roadbed material in a mechanical drum inside of a humidity-controlled chamber. Roadbed stability was evaluated by measuring total suspended solids in runoff from a model roadbed during a simulated rain event. Although OGPW can share some chemical characteristics (e.g. Ca and Mg concentrations, TDS) with commercial products, their efficacy is often no better to slightly worse than untreated roads or those treated with water alone. All OGPW from the Appalachian Basin performed significantly worse than the ten commercial products tested. OGPW treated roads also lost up to 15% more mass (up to 100 kg more per mile) in simulated rain events compared to water-treated roads. The high ratio of sodium content found in OGPW from the Appalachian Basin makes them ineffective dust suppressants that contribute to dustier and less-stable roads that likely have higher indirect costs than utilization of commercial dust palliatives. A field study of the impacts of chronic OGPW use as a road dust suppressant is presented in Chapter 3. Traces of OGPW including increased radium and bromide to chloride ratios are found in road aggregate, ditches, and wetland soil cores near historically treated roads. In wetland cores, age dating reveals that some of these tracers accumulate around the time that OGPW spreading in northwestern Pennsylvania was increasing dramatically. Finally, this chapter identifies areas for future research.
Book Synopsis Assessing the Effectiveness of Wyoming's CMAQ Unpaved Road Dust Suppression Program by : Christopher Zenas Chamberlin
Download or read book Assessing the Effectiveness of Wyoming's CMAQ Unpaved Road Dust Suppression Program written by Christopher Zenas Chamberlin and published by . This book was released on 2015 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Congestion Mitigation and Air Quality Improvement (CMAQ) Program, was implemented to provide funding to transportation projects that contribute to air quality improvements. Wyoming has made use of these funds for a number of years to apply dust suppressants to unpaved roads around the state. Many of these roads are impacted by oil and gas drilling activities. Decisions as to where these funds should be applied are based on subjective judgment. Methods for applying the suppressants to roads have also been based on engineering judgment, and there is no system in place for determining the effectiveness of dust treatment. The objective of this study is to assess the effectiveness of the CMAQ program in Wyoming. A second objective is to provide recommendations on optimizing future use of CMAQ funds. This study utilizes field data and comprehensive statistical analysis to prove the effectiveness of various dust suppressants. This includes monitoring dust suppressant application, surfacing aggregate type, traffic, weather, roadway performance, and fugitive dust emissions to provide a comprehensive assessment of the effectiveness of the dust suppression efforts paid for with CMAQ funds. Analysis of field data is also used to provide recommendations on developing a statistical model for the most cost effective use of future CMAQ funding. The result will be a systematic and clearly established method for allocating funds, and ensuring that they are being used in the best way possible.

Book Synopsis Explosions in Underground Coal Mines by : Jianwei Cheng
Download or read book Explosions in Underground Coal Mines written by Jianwei Cheng and published by Springer. This book was released on 2018-03-23 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the hazard of gas explosions in sealed underground coal mines, and how the risk of explosion can be assessed, modeled, and mitigated. With this text, coal mine operators and managers will be able to identify the risks that lead to underground mine gas explosions, and implement practical strategies to optimize mining safety for workers. In six chapters, the book offers a framework for understanding the sealed coal mine atmosphere, the safety characteristics that are currently in place, and the guidelines to be followed by engineers to improve upon these characteristics. The first part of the book describes the importance and characteristics of underground gas mine explosions in a historical context with data showing the high number of fatalities from explosion incidents, and how risk has been mitigated in the past. Chapters also detail mathematical models and explosibility diagrams for determining and understanding the risk factors involved in mine explosions. Readers will also learn about safety operations, and assessments for the sealed mine atmosphere. With descriptions of chapter case studies, mining engineers and researchers will learn how to apply safety measures in underground coal mines to improve mining atmospheres and save lives.
