# 641.21 Monitoring.

Scientific, analytic and/or reporting procedures shall be put in place, including appropriate monitoring of key environmental indicators, to assess and verify the potential environmental impacts of actions which are the subject of a CEE. All proposed actions for which an environmental document has been prepared shall include procedures designed to provide a regular and verifiable record of the actual impacts of those actions, in order, *inter alia,* to

(a) Enable assessments to be made of the extent to which such impacts are consistent with the Protocol; and

(b) Provide information useful for minimizing or mitigating those impacts, and, where appropriate, information on the need for suspension, cancellation or modification of the action.
