Abstract:
The Oregon Department of Transportation (ODOT) is conducting a study to determine roadwaste management options. Phase 1 consisted of a thorough review of regulations and standards, roadwaste characterization, current management practices, and new technology. This report documents the findings from Phase 1, focusing on road sweepings and stormwater vactor residuals, though the findings also help to clarify proper management of other roadwaste materials. No one set of regulations was identified that covers roadwaste management. Consequently, hazardous and solid waste, water quality, cleanup, and other rules are reviewed. Roadwaste characterization evolved during the 1990s; many tests were run and results varied widely. Total petroleum hydrocarbon (TPH) tests, used at underground storage tank (UST) cleanup sites, are not appropriate for evaluation of roadwaste due to H-C bond interference from natural organic constituents. Now, carcinogenic PAHs (seven heavy petroleum compounds) and heavy metals drive evaluation of risk. Fine particles (clays and silts) are more contaminated than coarse fractions. Dissolved contaminants in vactor liquids are low; however, high contamination loadings are often adsorbed to suspended solids. Identifying and separating differing roadwastes allows more ready management while requiring less frequent analysis. Practices reviewed address hot load separation, mainstream roadwaste, and vactor waste management. Many possibilities are identified for trials; it is expected that Phase 2 (Trial Implementation) will lead to further important finds. The report recommends that trials lead to the development of Best Management Practices to support statewide plan development by ODOT in Phase 3.
