2.1.9 Element 9: Control Pollutants <br /> The following pollutants are anticipated to be present on-site: <br /> Table 2—Pollutants <br /> Pollutant(List pollutants and source, if applicable) <br /> petroleum products <br /> chemicals stored in the construction areas <br /> Dust released from demolished sidewalks <br /> Solid waste <br /> All pollutants, including waste materials and demolition debris, that occur onsite shall be <br /> handled and disposed of in a manner that does not cause contamination of stormwater. Good <br /> housekeeping and preventative measures will be taken to ensure that the site will be kept clean, <br /> well organized, and free of debris. If required, BMPs to be implemented to control specific <br /> sources of pollutants are discussed below. <br /> Vehicles, construction equipment, and/or petroleum product storage/dispensing: <br /> ❑ All vehicles, equipment, and petroleum product storage/dispensing areas will be <br /> inspected regularly to detect any leaks or spills, and to identify maintenance needs to prevent <br /> leaks or spills. <br /> ❑ On-site permanent fueling tanks and petroleum product storage containers shall include <br /> secondary containment. <br /> ❑ Spill prevention measures, such as drip pans,will be used when conducting maintenance <br /> and repair of vehicles or equipment. <br /> ❑ In order to perform emergency repairs on site,temporary plastic will be placed beneath <br /> and, if raining, over the vehicle. <br /> ❑ Contaminated surfaces shall be cleaned immediately following any discharge or spill <br /> incident. <br /> Chemical storage: <br /> ❑ Any chemicals stored in the construction areas will conform to the appropriate source <br /> control BMPs listed in Volume IV of the Ecology stormwater manual. In Western WA, all <br /> chemicals shall have cover, containment, and protection provided on site,per BMP C 153 for <br /> Material Delivery, Storage and Containment in SWMMWW 2005 <br /> Excavation and tunneling spoils dewatering waste: <br /> ❑ Dewatering BMPs and BMPs specific to the excavation and tunneling(including <br /> handling of contaminated soils) are discussed under Element 10. <br /> Demolition: <br /> ❑ Dust released from demolished sidewalks,buildings, or structures will be controlled <br /> using Dust Control measures(BMP C140). <br /> ❑ Storm drain inlets vulnerable to stormwater discharge carrying dust, soil, or debris will be <br /> protected using Storm Drain Inlet Protection(BMP C220 as described above for Element 7). <br /> Page I18 <br />
