EVENT

ACTION

 

ET

IC(E)

CAD

Heliport / Helicopter Operator

Action Level

1.       Notify IC(E), CAD and Heliport / Helicopter Operator;

2.       Carry out investigation;

3.       Report the results of investigation to the IC(E), CAD and the Heliport / Helicopter Operator;

4.       Discuss with the Heliport / Helicopter Operator and formulate remedial measures;

5.       Increase monitoring frequency to check mitigation effectiveness.

1.                                                                   Review the analysed results submitted by the ET;

2. Review the proposed remedial measures by the Heliport / Helicopter Operator and advise the ER accordingly;

3. Supervise the implementation of remedial measures.

1.       Confirm receipt of notification of failure in writing;

2.       Notify Contractor;

3.       Require Heliport / Helicopter Operator  to propose remedial measures for the analysed noise problem;

4.       Ensure remedial measures are properly implemented.

 

1.  Submit noise mitigation proposals to IC(E) & CAD;

2.  Implement noise mitigation proposals.

Limit Level

1.       Identify source;

2.       Inform IC(E), CAD, EPD and Heliport / Helicopter Operator;

3.       Repeat measurements to confirm findings;

4.       Increase monitoring frequency;

5.       Carry out analysis of Helicopter Operator’s working procedures to determine possible mitigation to be implemented;

6.       Inform IC(E), CAD and EPD the causes and actions taken for the exceedances;

7.       Assess effectiveness of Helicopter Operator’s remedial actions and keep IC(E), EPD and CAD informed of the results;

8.       If exceedance stops, cease additional monitoring.

1.       Discuss amongst CAD, ET, and Heliport / Helicopter Operator on the potential remedial actions;

2.       Review Heliport / Helicopter Operator remedial actions whenever necessary to assure their effectiveness and advise the CAD accordingly;

3.       Supervise the implementation of remedial measures.

1.       Confirm receipt of notification of failure in writing;

2.       Notify Heliport / Helicopter Operator;

3.       Require Heliport / Helicopter Operator to propose remedial measures for the analysed noise problem;

4.       Ensure remedial measures properly implemented;

5.       If exceedance continues, consider what portion of the work is responsible and instruct the Heliport / Helicopter Operator to reduce/stop the helicopter flights operated at the proposed helipad until the exceedance is abated.

1.       Take immediate action to avoid further exceedance;

2.       Submit proposals for remedial actions to IC(E)  within 3 working days of notification;

3.       Implement the agreed proposals;

4.       Resubmit proposals if problem still not under control;

5.       Reduce/Stop the helicopter flights operated at the proposed helipad as determined by the CAD until the exceedance is abated.
