This amendment regulates highway runoff water quality and its environmental impacts in coastal areas. Other legislation -- such as the Safe Drinking Water Act, the Endangered Species Act, the Resource Conservation and Recovery Act, and the National Wild and Scenic Rivers Act -- also contains provisions that may pertain to the water quality of highway runoff.

1.1.2. Other Laws and Regulations Imposing Water Quality Requirements on Departments of Transportation In addition to NPDES and TMDL requirements, highway runoff management techniques must be consistent with the objectives of nonpoint source control programs under Section 319 of the CWA and state coastal nonpoint pollution control plans developed under Section 6217 of the Coastal Zone Act Reauthorization Amendments.

Three primary subcategories are discussed briefly: the influence of average daily traffic on pollutant loadings, land use-based pollutant loads characterization, and the correlation of suspended sediment with nutrients and metals. Although the topic of highway runoff water quality characterization has been well studied, several more subtopics either were mentioned only briefly or were overlooked entirely in the GKY study.

With regard to the broader range of highway runoff management research and research needs, the GKY findings require expansion in the areas of receiving water impact assessment, highway runoff characterization, BMP evaluation, systems planning, and data collection and analysis.

Highway practitioners need toxicity testing protocols to address specifically the runoff entering different receiving water ecosystems. 3 Water Quality Management Information System Highway practitioners rely on published literature for addressing highway runoff management and control.

Consequently, it is possible that the reader may not completely agree with the inclusion of some research topics within a chosen research category. Therefore, in addition to cross-referencing studies, effort also was made to TABLE 1-2 Database document summary by primary categorization Primary Category Number of Documents Evaluation of Stormwater Control Facilities and Programs 332 Watershed-Based Approaches 73 Highway Runoff Characterization and Assessment 232 Receiving Waters Impact Assessment 80 Design of Stormwater Control Facilities and Programs 108 Other 59 TOTAL 884
