DRAFT 4 -28 -2010 5. Locations of all storm water management practices, infiltration areas, and • areas not to be disturbed during construction. 6. Normal water level, high water level, and emergency overflow elevations for the site and all associated ponding systems. 7. For discharges to cold water resources, a description and plans to control temperature from storm water runoff. 8. Location of areas where construction will be phased to minimize duration of exposed soil areas. Include map and calculations as necessary of areas of grubbing, clearing, tree removal, grading, excavation, fill, and other disturbance; areas of soil or earth material storage; quantities of soil or earth material to be removed, placed, stored, or otherwise moved on site, and delineated limits of disturbance. 9. Location and type of all temporary and permanent erosion prevention, sediment control, storm water runoff, and soil stabilization BMPs, along with procedures to be used to establish additional temporary BMPs as necessary for the site conditions during construction. 10. Methods to be used for final stabilization of all exposed soil areas. • 11. Designate a leak -proof or imperviously lined concrete washout area. • 12. Managing site waste of all unused building materials by properly disposing of wastes off site and not allowing wastes to be carried by runoff into a receiving channel or storm sewer system. 13. Sediment control measures must be in place before any land disturbing activity begins, and measures must remain in place and functional until the site is permanently stabilized. 14. Streets shall be cleaned and swept within 24 hours whenever tracking of sediment occurs and before the sites are left idle for weekends and holidays. 15. All temporary erosion and sediment control measures, such as silt fence and inlet protection devices, shall be installed prior to any land disturbance activities and shall be removed within 30 days after permanent stabilization is attained. All storm sewer systems and drainage ways must be flushed and cleaned of sediment accumulation and all accumulated sediments must be removed and properly disposed of. 15
