• Phase 1
• Construction sites impacting 5 acres or more
  (termed large construction sites)
• General and Individual Permits
• Tribes not subject to Rule
• Effectively replaced by Phase II

Storm Water Construction Program

• Phase II
• Construction sites impacting 1-5 acres (small
  sites) and 5 or more acres (large sites)
• General and Individual Permits
• Tribes subject to Rule
• Began March 2003

• CGP 2008 (New dischargers only until 2010)
• CGP 2010 (will include Effluent Limitation
  Guidelines)
• Discharges to Waters of the United States or to
  an MS4

8
Discharges

• Discharges associated with large and small
  construction sites
• Discharges from support activities
• Batch plants, staging yards, storage areas,
  borrow sites, excavation disposal areas, etc.
• Discharges co-mingled with discharges allowed
  under another NPDES permit

Allowable Non-Storm Water Discharges

• Fire fighting/fire hydrant flushing
• Non-detergent vehicle wash water
• Water for dust control
• Potable water/water line flushing
• Non-detergent building wash down water
• Pavement wash water (no toxic substances)
• Uncontaminated air conditioning condensate
• Uncontaminated ground water/spring water
• Foundation/footing drains
• Uncontaminated excavation dewatering
• Landscape irrigation

10
Control Measures and Practices

• Sediment Controls
• Sediment basins/sediment traps
• Off-Site Sediment Tracking Dust Control
• Construction entrances/water spraying
• Runoff Management
• Divert flows or retain/detain flows
• Erosive Velocity Control
• Velocity dissipation devices at outfalls/channels

11
Control Measures and Practices

• Post-Construction Storm Water Management
• Permanent BMPs sediment/infiltration basins
• Construction Waste Materials
• Control/collect/dispose wastes
• Non-Construction Wastes
• Strom water from concrete or asphalt batch plants
• Erosion Control Stabilization
• Stabilize disturbed areas/protect existing veg

12
Control Measures and Practices
