The system is a small but important component of the national freight system, particularly for bulk commodities. The study committee finds that, in order to ensure efficient use of limited navigation resources, the most critical need for the inland waterways system is a sustainable and well-executed plan for maintaining system reliability and performance. Reliability and performance will depend on placing higher priority on investments in operations and maintenance (O&M). Without a funding strategy that prioritizes system preservation, maintenance may continue to be deferred, which would result in further deterioration and in a less cost effective and less reliable system.The committee finds that more reliance on a “user-pays” funding strategy for the commercial navigation system is feasible, would generate new revenues for maintenance, and would promote economic efficiency.The committee suggests that an asset management program focused on economic efficiency, fully implemented and linked to the budgeting process, would help prioritize maintenance spending and ascertain the funding levels required for reliable freight service.View the TRB Special Report 315 webcast.View the press release. %0 Book %A Transportation Research Board %A National Academies of Sciences, Engineering, and Medicine %E Barrett, Michael %E Katz, Lynn %E Taylor, Scott %E Sansalone, John %E Stevenson, Marty %T Measuring and Removing Dissolved Metals from Stormwater in Highly Urbanized Areas %D 2014 %U https://nap.nationalacademies.org/catalog/22389/measuring-and-removing-dissolved-metals-from-stormwater-in-highly-urbanized-areas %> https://nap.nationalacademies.org/catalog/22389/measuring-and-removing-dissolved-metals-from-stormwater-in-highly-urbanized-areas %I The National Academies Press %C Washington, DC %G English %K Transportation and Infrastructure %P 172 %X TRB’s National Cooperative Highway Research Program (NCHRP) Report 767: Measuring and Removing Dissolved Metals from Stormwater in Highly Urbanized Areas presents prototype best management practices (BMPs) for the removal of dissolved metals in stormwater runoff.The report presents three conceptual configurations in detail: two vault system configurations for urban and rural settings, and an inlet scupper with media for bridge deck drainage systems.The report also includes standard protocols to accurately measure the levels of dissolved metals in stormwater. Practical guidance on the use of these protocols is provided in an appendix to the final report. The report is accompanied by an Excel spreadsheet on CD designed to assist in sizing the filter bed in the vaults and the bridge deck inlet scupper.The CD is also available for download from TRB’s website as an ISO image.
