Action Level With the numerical values presented in
Table 1, when any of the response variable for dolphin acoustic behaviour recorded in the construction phase monitoring
is 20% lower or higher than that
recorded in the baseline monitoring, or when there is a shift of 3 hours or more in peak occurrence at B2 Site (i.e. 00:00 – 01:00), the action level should be triggered |
1.
Repeat statistical data analysis to confirm findings; 2. Review
all available and relevant data to ascertain if differences are as a result
of natural variation or seasonal differences; 3. Identify source(s) of impact; 4.
Inform the IEC, SO and Contractor; 5. Check monitoring data; 6.
Carry out audit to ensure all dolphin protective measures are implemented
fully and additional measures be proposed if necessary |
1.
Check monitoring data submitted by ET and Contractor; 2.
Discuss monitoring with the ET and the Contractor; |
1.
Discuss with the IEC the repeat monitoring and any other measures proposed by
the ET; 2.
Make agreement on measures to be implemented. |
1.
Inform the SO and confirm notification of the non- compliance in writing; 2.
Discuss with the ET and the IEC and propose measures to the IEC and the SO; 3. Implement
the agreed measures. |
Limit Level With the numerical values presented in
Table 1, when any of the response variable for dolphin acoustic behaviour recorded in the construction phase monitoring
is 40% lower or higher than that
recorded in the baseline monitoring, or when there is a shift of 6 hours or more in peak
occurrence at B2 Site (i.e. 00:00 – 01:00), the limit level should be triggered |

fully and additional measures be proposed if necessary 7.
Discuss additional dolphin monitoring and any other potential mitigation
measures (e.g. consider to temporarily stop relevant portion of construction
activity) with the IEC and Contractor. |
1.
Check monitoring data submitted by ET and Contractor; 2.

Review proposals for additional monitoring and any other measures submitted
by the Contractor and advise ER accordingly. |
