Background: The Federal Coastal Zone Act Reauthorization Amendments of 1990, <br /> Section 6217 (CZARA) contain a requirement that local governments enact management <br /> measures to reduce the potential pollution of natural bodies of water (such as the ocean, <br /> rivers, streams, lakes and ponds) from storm water runoff in urban azeas. This is a <br /> program to control non-point source pollution from rainwater that runs off from <br /> developed areas, such as streets, parking lots, and buildings. The management measures <br /> require that the initial runoff from such areas, sometimes called the "first flush", be cleaned <br /> by being infiltrated into the ground through drywells or other porous drainage systems, or <br /> through grassy areas such as vegetated swales, or through sand filters, or by being kept in <br /> settling basins. It is generally thought that the bulk of the chemicals that may have the <br /> potential to pollute natural bodies of water are contained in the "first flush" -the first <br /> runoff after a hard rain. The primary goal of the program is to reduce the potential for <br /> water pollution from sediments and suspended solids in the storm water runoff. It applies <br /> to areas after construction has been completed. While construction is still underway, the <br /> primary permit requirements that deaf with runoff aze the National Pollution Dischazge <br /> Elimination System (NPDES) permit and County grading and grubbing permits. <br /> One potential penalty for failure to enact such management measures is that the <br /> local government could lose its Coastal Zone Management Act funding. The Hawaii <br /> County Planning Department receives about $300,000 annually which it uses in its various <br /> -1- <br /> <br />
