Segregating an activiry that is the most significant source of pollutants from other activities that cause little or no pollution may lower the cost of enclosure or covering to a reasonable level. A method commonly used in large industrial complexes where much of the process equipment is exposed is to place curbin@ around the immediate boundary of the individual processes. The stortn drains from these interior areas discharge to the process wastewater !reatment system. Dischareine stormwater te a nrivate, orocess wastewater treatment svstem: In general, the City will �ot allow discharge of stortnwater into the public sanitarv sewer system, unless the site is served by combined storm and sanitary sewer system. However, some industries may have their own process wastewater treatment system with finai disposal directly to the receiving water. Stormwater from areas of significant pollutior. sources can be plumbed to the process treatment system as long as the system's [reatment capacity is not exceeded. Dischareine srnall. hi¢h frequencv stortns to a dead-end sw.io: The feasibiliry of this BMP would be limited to those few activities which contribute unusuaily high concentrations of pollutants and/or ��Ilutants of unusual concem and would be used only when other options •.veren't available. Regular pumping of the sump, with appropriate disposal of the wastewater, is required. Note: Any floor drains necessary in buildings or covered areas must discharge to the sanitary or process wastewater sewers or a dead-end sump. Discharges to the sanitary sewer must meet the City's Industrial Pretreatment Program requirements (see Section 4-3.1). 4-2Z.9 BMP S1.80 EMERGENC Y SPILL CLEANUP PLANS Owners of facilities engaged in storing, p.ocessin¢, or r<�(ining oil and/or oil products are required by F�deral ?.,:w to have a Spill Prevention and Control Plan (SPCP).

The plan shall contain a site plan showing the Iecation of storage areas for chemicals, the locations of stortn drains, and the direction of slopes iowards those draies, and the location and description of any devices to stop spills from leaving the site such as positive cor.trol valves. 3. The plan shall describe notification procedures to be used in the event of a spill, such as key personnel and outside agencies. The Ciry of Everett Public Works Department and DOE shall be notified irnmediatelv if the spill may reach surface waters or sanitary or stortn sewers.
