“…The PEC/PNEC approach compares the predicted environmental concentration (PEC) of any pollutant with the predicted environmental tolerance level or the concentration giving no observable effect (PNEC) in the marine environment. The tool has been applied in quantitative environmental risk assessment in the North Sea Environmental Impact Assessment studies, both on a local and regional scale [3,4,5].…”

As a result of this cooperation, the target for the Norwegian offshore operators is set to achieve "zero harmful discharges" to the marine environment within 2005. The need for a system to quantify and document the potential harm of different discharges became evident as a result of this, and thus, the Environmental Impact Factor (EIF) for produced water discharges was developed in 1999 (presented at the SPE HSE 2000).This management tool, based on environmental risk assessment principles known from the EUs Technical Guideline Document (TGD) [14], has now been fully implemented in all Statoil's fields in the North Sea. The present paper outlines the utilisation of the EIF as a management tool and environmental performance indicator, and gives a number of practical examples of application of the system. The EIF has since 1999 also been developed further to cover discharges from drilling operations. Several pilot studies have been undertaken during this development, and the present paper gives the status of this activity and shows examples from drilling waste risk assessment in the Caspian Sea and the Faroe-Shetland channel.Further development of the EIF based risk management systems also includes linking air emissions and discharges to sea in a total environmental balance approach. The present paper will outline how this is handled in our present risk management system.
