Available in PDF, EPUB and Kindle. Book excerpt: This is one of four final documents of an investigation dealing with the characterization of stormwater runoff pollutant loads from highways, and the prediction of water quality impacts they cause. Study results are based on monitoring data from 993 individual storm events at 31 highway runoff sites in 11 States. Impact prediction is based on a methodology previously developed and applied to urban runoff and adapted for highway runoff applications. This document provides a step-by-step procedure for computing the estimated impacts on water quality of a stream or lake that receives highway runoff. Guidance is provided for evaluating whether or not a water quality problem will result, and the degree of pollution control required to mitigate impacts to acceptable levels.

This book was released on 1993 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to highway design engineers, maintenance engineers, environmental personnel, administrators, and others responsible for the design, operation, and maintenance of stormwater management for highways and ancillary facilities. Information is presented on the basic hydrology needed to assess stormwater impacts and on the effectiveness of stormwater management techniques. Designers of highway facilities must consider stormwater management requirements within the context of both localized runoff impacts, as well as downstream effects of runoff. This report of the Transportation Research Board describes the management of both stormwater quantity and stormwater quality. Stormwater quantity includes an overview of methods of estimating runoff and management control practices. Stormwater quality management includes discussions of the most prevalent pollutants and best management practices (BMP) to minimize pollutants from transportation facilities. Various types of structural and non-structural methods are described, including their design considerations and efficiencies. Several stormwater management models are described, with special concern for highway applications. Highlights from the 1990 National Pollutant Discharge Elimination System (NPDES) permits are presented.

This book was released on 2013 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The intent of this synthesis is to collect information on the types of best management practices (BMPs) currently being used by state departments of transportation (DOTs) for meeting total maximum daily load (TMDL) water quality goals for stormwater runoff. The study approach includes two major components: interviews with 12 state DOTs to identify the existing state of the practice as it relates to TMDL implementation, and a review of selected literature sources based on the criteria of highways, TMDLs, BMP performance, and BMP cost to stay consistent with the goals of this synthesis. In particular, detailed quantitative BMP performance and cost data, including life-cycle costs, are presented, which builds significantly on previous studies of this nature. The impetus for this study was to help fill in a significant information gap on what types of BMPs are cost-effective for specific use in linear highway applications for TMDL implementation purposes. Even with the advent of new low-impact development/green infrastructure practices, there remain a lack of effective BMP technologies and nonstructural controls (e.g., source control and water quality credit trading) for DOTs to implement for National Pollutant Discharge Elimination System permit compliance. This problem will only grow larger as new TMDLs are continually being developed, and many DOTs are unprepared both technically and economically to cope with the additional requirements (some states already have 60+ TMDLs in which they are a named stakeholder). In an effort to help state DOTs with TMDL implementation, a simple user-friendly BMP matrix/toolbox with quantitative performance and, where available, life-cycle cost data for various structural and nonstructural BMPs is presented. Some of the more common TMDL pollutants of concern (sediment, nutrients, fecal coliform, and metals) are focused to maximize applicability for state DOTs. The performance and cost data were derived from numerous literature sources including the International Stormwater BMP Database, which currently consists of more than 400 studies. This study is designed to help promote information exchange and technology transfer among DOTs for the mutual benefit of all highway managers faced with TMDL implementation. Conclusions from this synthesis are briefly highlighted here by general topic area, with more details provided in chapters four and five. Performance for structural BMPs varied by pollutant and BMP type; however, certain trends did emerge from the literature review. In general, total suspended solids (TSS) appear to be relatively easy to treat with a broad range of BMPs, including infiltration basins, sand filters, and bioretention. Nutrients (especially total nitrogen) can be more challenging to remove; nonetheless, some BMPs (e.g., Austin sand filters for total nitrogen and infiltration basins for total phosphorus) showed some promise. Fecal coliform data were limited; however, several BMPs were documented as being effective, including infiltration basins, and infiltration trenches, among others. Additional BMP performance data from the International Stormwater BMP Database support the view that media filters and retention ponds are consistently effective for a wide variety of TMDL pollutants, including TSS, nutrients, fecal coliform, and total metals. This conclusion is based on statistics that show that median concentrations of these pollutants were statistically lower in effluent concentrations compared with influent concentrations based on a large number of studies from around the country (although not all highway related). Overall, while these BMPs may be generally effective across a range of environmental conditions, obtaining local site-specific BMP monitoring data would be preferable for developing individual state DOT TMDL programs. Performance data are also presented for nonstructural practices such as street sweeping, catch basin cleaning, and tree planting. Quantitative performance data are generally lacking in the literature for these types of BMPs. The limited information found suggests that street sweeping and catch basin cleaning may potentially be effective strategies for reducing TSS, nutrients, and metals provided they are performed frequently enough and the right technology is used (in the case of sweeping). Tree planting and stream restoration were documented as having some water quality benefits for nutrients. Notably, anti-icing management has been successfully demonstrated in New Hampshire, where a 20% reduction in chlorides was achieved by upgrading the technology on snow plows in response to a chloride TMDL. In addition to performance, life-cycle cost data are presented where available. However, the cost information could not be adequately synthesized owing to differences in cost estimating approaches, reporting units, variability in costs among states and regions, and inconsistencies in BMP naming conventions. This also prevented a true cost-benefit analysis. However, numerous sources of life-cycle cost data, as well as sources for individual cost elements such as design, construction, and operation and maintenance, are provided where the interested reader may obtain more detailed information. Given the differences in cost from one region to another, the reader is encouraged to obtain cost data that are most relevant to their state. Hyperlinks are provided in the BMP matrix/toolbox where one may access examples of reports with detailed life-cycle cost data, and numerous additional cost sources are cited throughout the section on Highway Best Management Practices in chapter three. There appear to be several common elements to developing an effective TMDL implementation program, all of which have the potential to benefit DOTs by helping them receive a more equitable waste load allocation and developing a more manageable TMDL program. The key elements are listed here (although not all may apply to every DOT): Increase awareness and training within the DOT on TMDL issues, especially in cases where the DOT is named a stakeholder in only a few TMDLs (or none). Develop off-site watershed partnerships and collaborate with other stakeholders to ensure cost-effective approaches based on economies of scale and to promote information sharing and technology transfer among stakeholders. Collaborate with the state regulatory agency during the TMDL development process, especially early in the process. Estimate pollutant loads generated within the DOT right-of-way (either through water quality monitoring or modeling) and predict potential load reductions from various BMP implementation scenarios. Although some DOTs had relatively successful TMDL programs, others clearly faced a number of challenges. The primary challenges were limited financial resources, a lack of effective BMP technologies for linear highway applications, and difficulties in navigating complex regulatory environments where TMDL-related requirements were either inconsistently enforced or restricted the flexibility of the DOT in implementing BMPs of their choice. Further research is suggested on the following topics: long-term adverse environmental and cultural aspects of BMP implementation; new and innovative BMP technologies suitable for the highway environment; more studies on BMP longevity, life-cycle costs, and maintenance costs and standards; and alternative and creative solutions to addressing emerging TMDLs for less traditional pollutants such as biological integrity, sediment toxicity, and organic compounds (e.g., vehicle source control, water quality trading)"--Pages 1-2.

Available in PDF, EPUB and Kindle. Book excerpt: "This report describes the methods used to collect stormwater runoff and evaluate a street sweeping program on U.S. Highway 151 in Madison, Wisconsin. The study was a cooperative effort among the Wisconsin Department of Transportation (WisDOT), U.S. Geological Survey, and Wisconsin Department of Natural Resources. In a swept highway section, samples were collected to determine street dirt yields before and after a cleaning from either a vacuum-assisted or a mechanical-broom sweeper machine. Sweeping frequencies of twice per day, once per week, and once every two weeks were used during the study. On an unswept highway section of the study, street dirt yields are presented as weekly collections, and before and after runoff events. Water quality concentrations and flows are also presented for the unswept highway section. Average concentrations of selected contaminants are compared to concentrations measured in other studies of highway runoff"--Technical report documentation p.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this manual is to gather and to synthesize the results of past documentation and research on highway stormwater runoff into a single-volume user's manual on water quality impact assessment and mitigation. The manual will be useful to highway designers and environmental professionals by presenting the available and appropriate impact prediction and mitigation tools for use during highway project planning and development activities. The development of this document had three components: a literature search on existing research results and operational findings on highway stormwater runoff that identifies existing water quality impact assessment and mitigation techniques; interviews with highway practitioners concerning the use of research results including maintenance of mitigation measures; and synthesis of the accumulated information into this single-volume, practical guidance manual. This manual is intended to be a self-contained desk reference for highway practitioners. An extensive bibliography is included, and the mathematical nomenclature is unified among the sections.

Available in PDF, EPUB and Kindle. Book excerpt: In order to obtain the necessary detailed design guidelines for storm water best management practices (BMPs) included in the Virginia Department of Transportation's storm water manual, a field program was initiated in 1991 for testing the pollutant removal efficiency of selected practices. A dry detention pond with a small, highly impervious drainage area and a vegetated swale draining runoff from an urban highway were selected for the study. Manual as well as automatic sampling methods were used to monitor storm water runoff into and out of the two facilities. Pollutant removal efficiencies were calculated by a mass balance method. Pollutants examined included total suspended solids, total phosphorus, and total zinc. Preliminary data showed that, if properly designed, these types of facilities can be an effective tool for removing storm water pollution from highway runoff.

Download or read book Approaches for Determining and Complying with TMDL Requirements Related to Roadway Stormwater Runoff written by Anna Lantin and published by . This book was released on 2019 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: State DOTs are increasingly subject to Total Maximum Daily Load (TMDL) requirements for water quality improvement that are implemented through National Pollutant Discharge Elimination System (NPDES) permits. As a result, state DOTs may incur significant costs to construct, operate, maintain, and monitor performance of best management practices and other stormwater treatment facilities that treat stormwater from sources outside the right-of-way, as well as stormwater from roadway sources. TRB’s National Cooperative Highway Research Program (NCHRP) Research Report 918: Approaches for Determining and Complying with TMDL Requirements Related to Roadway Stormwater Runoff describes how to evaluate TMDLs and develop a plan to comply with the requirements of a TMDL. The methods provide a robust approach to determining the pollutants of concern and how to assess the contribution of the roadway while understanding other important factors that affect overall pollutant loads, including adjacent land uses and watershed conditions and characteristics. A set of presentation slides summarizing the project that developed the report is available for download.

Allan and published by . This book was released on 2004 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents the development of a methodology to estimate pollutant loading from stormwater runoff from North Carolina. A summary of regression-based pollutant loading models developed for highway runoff from the literature is presented. The regression models based on average daily traffic (ADT) and percent impervious coverage (IMP) developed by Wu and Allan (2001) are applied to the I-40 corridor within NC. Multiple regression models based on traffic conditions, previous storm conditions, antecedent dry period and storm characteristics are developed for five NC highway sites and compared to similar regression models developed for highway sites near Austin, Texas. Finally, traditional digital elevation models (DEM) and Lidar topographic information is used in conjunction with the GIS-based NC sensitive water crossing point coverage to define highway drainage areas and their impervious cover characteristics for two case studies in eastern NC.
