Abstract:

Storm water runoff from highways and other paved surfaces may contain levels of petroleum, metals, and particulates that could affect the environment. To address potential environmental impacts, the federal National Pollutant Discharge Elimination System (NPDES) regulations were enacted in 1990. The Washington State Department of Ecology is the regulatory authority for the NPDES program. Municipalities with populations exceeding 100,000, as well as transportation departments, are obligated to obtain a municipal NPDES permit, which will provide conditions for storm water management. The Washington State Department of Ecology issues permits on a watershed basis, and a single municipal permit will be issued for that watershed. Washington State Department of Transportation (WSDOT) staff coordinate with the municipalities to develop a practical storm water management plan for each watershed that places sites in priority order for improvement and that reflects a sharing of costs. Approximately 2,500 storm water outfalls along 1288 km of state highway have been inventoried to characterize the discharge quality and therefore potential impact on surface waters of the state. A prioritization scheme was developed that will be used in selecting areas for highway storm water improvement. WSDOT maintenance facility storm water issues are not covered under the WSDOT municipal permit. However, through the development of the city and county municipal permits, all WSDOT property storm water will have to be managed. The WSDOT has and will continue to recognize quality-of-environment issues in all phases of planning, construction, and operation. The storm water quality impacts of WSDOT facilities and highways must be balanced with other traditional goals of the department.
