In addition, each installation will have permit for re‐injection of produced water. Permits now extend to pipelines, under
the 2011 amendments to the OPPC regulations.
Monthly reporting of produced water discharges is via EEMS. Bi‐annual sampling and analysis is required for total
aliphatics, total aromatics and total hydrocarbons (BTEX, NPDs, PAHs, organic acids, phenols and heavy metals). Other
specific monitoring requirements are attached to each permit.

OSPAR Recommendation 2001/1 (as amended) requires that no individual offshore installation exceeds a performance
standard for dispersed oil of 30 mg/l for produced water discharged into the sea. It also requires a 15% reduction in the
discharge of oil in produced water from 2006 measured against a 2000 baseline; controlled by the issue of permits to
each installation. This is implemented under OPPC.
Regulator: DECC
Requires a permit for hazardous drainage and non‐hazardous drainage discharges. Specific monitoring and reporting
requirements are required on each schedule permit. Reporting is via EEMS.
Permits now extend to pipelines under the 2011 amendments and to CCS activities under the Energy Act 2008
(Consequential Modifications) (Offshore Environmental Protection) Order 2010.
Regulator: DECC
The OPPC requires a permit for well workover, intervention and service fluid discharges. Under these regulations a
permit is not required for the discharge of OBM/OPF and SBMs as these are permitted under the Offshore Chemical
Regulations 2002 (as amended). However any material being discharged or reinjected that has been contaminated by
hydrocarbons from the reservoir will require a permit. Specific monitoring and reporting requirements are included on
each schedule permit and reporting is via EEMS.
Note: Under the Energy Act 2008 (Consequential Modifications) (Offshore Environmental Protection) Order 2010;
permits now extend to carbon sequestration activities.
Regulator: DECC
The OPPC requires a permit for maintenance and cleaning discharges, however it may be possible to include it in an
existing permit. Permits extend to both installations and pipeline under the Offshore Petroleum Activities (Oil Pollution
