Stormwater BMP Inspection

Inspection template for SWPPP stormwater BMP checks covering perimeter controls, inlet protection, sediment basins, and corrective actions under CGP requirements.

Inspection Details and Site Conditions

• Inspection date and time recorded
• Inspector identified as qualified competent person
• Recent rainfall or triggering event documented
• Weather and site conditions noted
• Active construction areas identified

Perimeter Controls and Site Stabilization

• Perimeter controls installed in required locations
  Verify silt fence, wattles, berms, or other perimeter BMPs are present where runoff could leave the disturbed area.
• Perimeter controls are intact and functioning
  Check for tears, undercutting, overtopping, bypass flow, collapsed posts, or gaps at joints and ends.
• Sediment accumulation at perimeter controls is within allowable limits
  Measure or estimate sediment buildup and verify it has not reached a level that reduces BMP effectiveness.
• Disturbed soil areas are stabilized or scheduled for stabilization
  Check for temporary or permanent stabilization such as mulch, seed, erosion control blanket, or paving.
• Stockpiles are protected from runoff and erosion
  Verify stockpiles are covered, bermed, or otherwise protected and not discharging sediment.
• Evidence of off-site sediment tracking is controlled
  Check entrances, exits, and adjacent pavement for tracked sediment and verify cleanup is in progress if needed.

Inlet Protection and Conveyance Controls

• Storm drain inlet protection installed where required
  Verify inlet protection is present at curb, drop, and yard inlets receiving runoff from disturbed areas.
• Inlet protection is secure and not bypassed by runoff
  Check for undercutting, displacement, clogging, overtopping, or flow around the control.
• Inlet protection is free of excessive sediment and debris
  Confirm accumulated sediment, trash, and debris do not reduce intake capacity or create flooding risk.
• Conveyance channels, swales, and ditches are stable
  Inspect for erosion, scour, undermining, or sediment deposition that could alter flow paths or discharge quality.
• Dewatering or pumped discharge is controlled and filtered
  If active dewatering is present, verify discharge is routed through approved filtration or sediment control measures.

Sediment Basins and Temporary Controls

• Sediment basin is constructed per SWPPP design
  Verify basin dimensions, embankment condition, outlet structure, and emergency spillway appear consistent with the approved plan.
• Sediment basin water level and freeboard are acceptable
  Confirm the basin is not overtopping and freeboard is maintained above the sediment storage and design water level.
• Sediment accumulation in basin is within maintenance threshold
  Estimate or measure sediment depth and verify cleanout is scheduled before storage capacity is compromised.
• Outlet structure and overflow controls are unobstructed
  Check skimmers, risers, pipes, trash racks, and spillways for blockage, damage, or bypass conditions.
• Evidence of erosion or embankment instability is absent
  Inspect embankments, side slopes, and downstream areas for sloughing, seepage, piping, or rills.

Housekeeping, Spill Prevention, and Corrective Actions

• Waste, trash, and construction debris are contained
  Verify litter, packaging, and debris are not exposed to runoff or entering stormwater conveyances.
• Potential pollutant sources are protected from stormwater contact
  Check fuel, chemicals, concrete washout, and material storage areas for secondary containment and cover where required.
• Observed deficiencies documented with corrective actions
  Record each non-conformance, responsible party, due date, and interim control needed to prevent discharge.
• Corrective actions completed or assigned with deadline
  Confirm immediate repairs or assign follow-up actions for any failed BMPs, including reinspection timing.
• Follow-up inspection required
  Indicate whether a reinspection is needed after corrective actions are completed.
