  Check: Verify ISPPC is valid, properly issued for vessel size (≥400GT or ≥15 persons), signed and endorsed by flag state authority, not expired
• Area: Sewage treatment plant IMO type approval certificate missing or invalid
  Check: Confirm STP holds valid IMO MEPC 227(64) certificate (or MEPC 159(55) for older units), check certification class (STP type approval letter), verify not lapsed
• Area: Direct sewage discharge valve not sealed or incorrectly secured
  Check: Inspect discharge valve seals, verify valve is sealed shut when in port or within 3 nautical miles from shore, confirm mechanical lock/weld, check pump discharge isolation
• Area: Sewage treatment plant not operational or inadequate capacity for crew
  Check: Test plant start-up sequence, verify blower/pump operation, check aeration and treatment tank water levels, confirm adequate treatment time (typically 8-15 hours retention), measure actual vs. design capacity, review operational log
• Area: Monthly effluent quality testing records missing or deficient (BOD, COD, TSS, E.coli)
  Check: Request last 12 months of effluent test reports, verify parameter compliance with MEPC 227(64) limits (BOD ≤25mg/L, COD ≤125mg/L, TSS ≤35mg/L, fecal coliform <250 CFU/100mL), check testing lab certification, confirm disposal location recorded

  Check: Test plant start-up sequence, verify blower/pump operation, check aeration and treatment tank water levels, confirm adequate treatment time (typically 8-15 hours retention), measure actual vs. design capacity, review operational log
• Area: Monthly effluent quality testing records missing or deficient (BOD, COD, TSS, E.coli)
  Check: Request last 12 months of effluent test reports, verify parameter compliance with MEPC 227(64) limits (BOD ≤25mg/L, COD ≤125mg/L, TSS ≤35mg/L, fecal coliform <250 CFU/100mL), check testing lab certification, confirm disposal location recorded

• Chlorination tablet exhaustion
• Aeration insufficient
• Effluent quality deterioration

• Area: International Sewage Pollution Prevention Certificate (ISPPC) validity and authenticity
  Check: Verify ISPPC is valid, properly issued for vessel size (≥400GT or ≥15 persons), signed and endorsed by flag state authority, not expired
• Area: Sewage treatment plant IMO type approval certificate missing or invalid
  Check: Confirm STP holds valid IMO MEPC 227(64) certificate (or MEPC 159(55) for older units), check certification class (STP type approval letter), verify not lapsed
• Area: Direct sewage discharge valve not sealed or incorrectly secured
  Check: Inspect discharge valve seals, verify valve is sealed shut when in port or within 3 nautical miles from shore, confirm mechanical lock/weld, check pump discharge isolation
