The competent authority shall base the boundaries for monitoring and reporting of emissions from geological storage of CO₂ on the delimitation of the storage site and storage complex as specified in the permit pursuant Directive 2009/31/EC. Where leakages from the storage complex are identified and lead to emissions or release of CO₂ into the water column, the operator shall immediately carry out all of the following:

1. (a)

   notify the competent authority;

2. (b)

   include the leakage as an emission source for the respective installation;

3. (c)

   monitor and report the emissions.

Only when corrective measures in accordance with Article 16 of Directive 2009/31/EC have been taken and emissions or release into the water column from that leakage can no longer be detected shall the operator delete the respective leakage as emission source from the monitoring plan and no longer monitor and report those emissions.

Each operator of a geological storage activity shall consider at least the following potential emission sources for CO₂ overall: fuel use by associated booster stations and other combustion activities including on-site power plants; venting from injection or enhanced hydrocarbon recovery operations; fugitive emissions from injection; breakthrough CO₂ from enhanced hydrocarbon recovery operations; and leakages.
