Download or read book Evaluating Dust Suppressant Efficacy and Roadbed Stability of Dirt and Gravel Roads written by Andrew Eck and published by . 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.

This book was released on 2022-01-12 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the study of chemical dust suppression in mine dust pollution control by means of theories, experiments, computer simulation, and case application, aiming at providing chemical dust suppression solutions for mining worksites. It has seven chapters, including the following contents: (1) introduces fundamental theories and applications of chemical dust suppression, analyzes the dust source intensity of worksites and the mechanisms of dust generation, and summarizes the dust control measures for different mining worksites. (2) According to the mechanisms of dust generation in different mining worksites, targeted dust suppressants were developed. Through optimization by monomer experiment and orthogonal experiment, the optimum formula of different types of dust suppressants was obtained, and its properties were characterized. (3) The dust suppressant field application process was introduced, and the economic benefits were analyzed. This book is expected to provide valuable references both for researchers and engineering technicians engaged in environmental engineering, safety engineering, occupational health, and mining metallurgical engineering, and it also serves as a textbook for graduate students in above disciplines.

Book excerpt: More than 50 percent of U.S. roadways are gravel roads, making them a vital part of our transportation system. One of the drawbacks and biggest complaints about gravel roads is the dust they produce when vehicles drive over them. Residents that live on gravel roads deal with the dust that settles on their homes, yards, and parked cars, potentially reducing their quality of life. Dust can also have adverse effects on air quality and the environment and reduce the safety for drivers due to impaired vision. To control the dust on gravel roads, local agencies apply various dust suppressants on their roadways, mainly calcium chloride and magnesium chloride. However, many other dust suppressant options exist. The Minnesota LRRB has developed this document, Dust Control of Aggregate Roads, A Brief Synthesis of Current Practices, to provide local agencies with a summary of research that has been completed on various dust suppressants, their effectiveness, and impacts. Results from two surveys that document dust suppressants that local agencies (within Minnesota and Iowa) use is included as well.

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 excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Available in PDF, EPUB and Kindle. Book excerpt: This manual provides guidance for dust control methods and materials that can be used successfully at airfields and heliports to stop dust from forming naturally or as a result of man's activities and to control dust in areas directly impacted by man's activities. Dust develops naturally in denuded or sparsely vegetated areas and in most unpaved, sparsely vegetated areas occupied by man. (Man's activities may be detrimental to existing vegetation and create a dust problem.) Dust is created in unsurfaced areas subjected to concentrated foot or vehicular traffic, and is usually a problem on shoulders of surfaced airport and heliport traffic areas. Dust control becomes desirable when man needs to occupy land areas adjacent to the dust producing areas or is required to conceal military activities. The control of dust is also an important factor to consider for lengthening the life of vehicles and their engines. This manual discusses dust control methods and materials that have proven effective for treating soil surfaces to reduce dust; provides suggestions for rates and methods of application of materials for various soil types and environmental conditions; and discusses factors, such as availability, curing time, durability, logistics, and economics, that may be significant in the ultimate choice of material. Economic solutions for dust control of very large areas with little or no vegetation and no direct impact from man are presented in an appendix.

This book was released on 2015-05-09 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the mining and processing of minerals, the mined ore undergoes a number of crushing, grinding, cleaning, drying, and product sizing operations as it is processed into a marketable commodity. These operations are highly mechanized, and both individually and collectively these processes can generate large amounts of dust. If control technologies are inadequate, hazardous levels of respirable dust may be liberated into the work environment, potentially exposing workers. Accordingly, federal regulations are in place to limit the respirable dust exposure of mine workers. Engineering controls are implemented in mining operations in an effort to reduce dust generation and limit worker exposure.
