Stormwater Pollution Prevention Plan <br /> 0 Assess the site conditions and construction activities that could <br /> impact the quality of stormwater, and <br /> ❑ Assess the effectiveness of erosion and sediment control measures <br /> used to control the quality of stormwater discharges. <br /> • A Certified Erosion and Sediment Control Lead shall be on-site or on-call <br /> at all times. <br /> • Whenever inspection and/or monitoring reveals that the BMPs identified <br /> in this SWPPP are inadequate, due to the actual discharge of or potential <br /> to discharge a significant amount of any pollutant, appropriate BMPs or <br /> design changes shall be implemented as soon as possible. <br /> Maintaining an Updated Construction SWPPP <br /> ■ This SWPPP shall be retained on-site or within reasonable access to the <br /> site. <br /> ■ The SWPPP shall be modified whenever there is a change in the design, <br /> construction, operation, or maintenance at the construction site that has, or <br /> could have, a significant effect on the discharge of pollutants to waters of <br /> the state. <br /> • The SWPPP shall be modified if, during inspections or investigations <br /> conducted by the owner/operator, or the applicable local or state <br /> regulatory authority, it is determined that the SWPPP is ineffective in <br /> eliminating or significantly minimizing pollutants in stormwater <br /> discharges from the site. The SWPPP shall be modified as necessary to <br /> include additional or modified BMPs designed to correct problems <br /> identified. Revisions to the SWPPP shall be completed within seven(7) <br /> days following the inspection. --- <br /> (East Response)As this project site is located east of the Cascade Mountain Crest,the project <br /> will be managed according to the following key project components: <br /> Phasing of Construction <br /> • The construction project is being phased to the extent practicable in order <br /> to prevent,to the maximum extent practicable,the transport of sediment <br /> from the development site during construction. Revegetation of exposed <br /> areas and maintenance of that vegetation shall be an integral part of the <br /> clearing activities during each phase. <br /> 14 <br />
