Elgin G4 leak: environmental impacts
Widespread consensus that the environmental impacts are minimal
Environment Monitoring Activities
2 Oil Spill Response Limited (OSRL) flights per day to monitor marine pollution
Regular survey flights by the National Centre for Atmospheric Science (NCAS)
Daily water samples taken in Elgin surroundings
Regular ROV surveys of seabed around conductor pipe
Leak flow rate estimated at an initial 2kg/s but quickly fell to less than 0.6kg/s
Gas composition: 70% methane + 30% ethane, butane, etc; no H2S traces
Surface sheen extended many kms, but was less than 1/10thof a micron thick
Light condensate that disperses naturally and easily: 50% evaporation in the
first 24 hours alone
Several independent chemical, sediment and & fish analyses confirmed no
direct marine contamination (eg, Scottish Government, etc)

Twice daily aerial surveillance flights for sheen quantification 115flights will have been undertaken by the final sortie planned on 6thJune
OSCAR Modelling from DGEP/HSE/ENV informs flight plans and alertsto neighbouring installations / transboundary lines if required.
OSIS modelling linked to aerial surveillance findings supportscondensate release rate calculation and daily PON1 updates to DECC
