| 摘要： | The results of past research on highway stormwater runoff are gathered and synthesized 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. A status report on the first phases of the study, literature search and interviews, is presented. The project has three components: (a) a literature search of existing research results and operational findings on highway stormwater runoff that identifies existing water quality impact assessment and mitigation techniques; (b) interviews with highway practitioners concerning the use of research results, including maintenance of mitigation measures; and (c) development of the single-volume, practical guidance manual. A detailed questionnaire was developed and sent to nine highway departments in different areas of the country (each of the FHWA regional offices). A major finding is that many of the departments recognize and follow the often restrictive water quality regulations associated with National Pollutant Discharge Elimination System Stormwater and Clean Water Act Sections 404 and 401. However, hard supporting data on highway runoff water quality impacts are generally not available and studies are based on extrapolative science and hypothecation. |
