摘要：	The United States EPA (Environmental Protection Agency) MS4 (Municipal Separate Storm Water Sewer System) Program regulations require municipalities and government agencies including the Louisiana Department of Transportation and Development (LADOTD) to develop and implement stormwater best management practices (BMPs) for linear transportation systems to reduce the discharge of various pollutants, thereby protecting water quality. An efficient and cost-effective stormwater BMP is urgently needed for elevated linear transportation projects to comply with MS4 regulations. This report documents the development of a first flush-based stormwater treatment device, the first flush reactor, for use on elevated linear transportation projects/roadways for complying with MS4 regulations. A series of stormwater samples were collected from the I-10 elevated roadway section over City Park Lake in urban Baton Rouge. Stormwater treatment experiments were conducted using three laboratory columns filled with different combinations of filter medium layers. Guidelines for design, field construction, operation, and maintenance of the first flush reactor are provided in this report to help environmental engineers and stormwater managers design and operate the first flush reactor properly and achieve the stormwater pollutant removal efficiency required in the MS4 program. / Title Note: Final rept.
