English to Spanish Other Engineering (general)

Not sure if in Spanish you can talk about opening and closing risks, would appreciate your thoughts and help with the above. Thanks!

Risk Closure
Where possible risks shall be fully mitigated through actions included in the project programme.
For those risks where this is not possible to completely mitigate, mitigation actions will be undertaken to reduce the impact or likelihood to an acceptable level.
Risk will be closed at either the working sessions or at the quarterly reviews.
