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
