Riverview Apartments <br />Stormwater Pollution Prevention Plan <br />• <br />• <br />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 />N/A <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. If <br />required, BMPs to be implemented to control specific 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 <br />prevent leaks or spills. <br />• On -site 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 <br />maintenance and repair of vehicles or equipment. <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 <br />WA, all chemicals shall have cover, containment, and protection provided on site, per <br />BMP C153 for Material Delivery, Storage and Containment in SWMMWW 2005 <br />Application of agricultural chemicals, including fertilizers and pesticides, shall be <br />conducted in a manner and at application rates that will not result in loss of chemical <br />to stormwater runoff. Manufacturers' recommendations for application procedures <br />and rates shall be followed. <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 <br />will be protected using Storm Drain Inlet Protection (BMP C220 as described above <br />for Element 7). <br />CPH Project No. 0024-17-037 <br />CP I H CONSULTANTS <br />August 28, 2018 <br />Page 14 <br />
