IEC

Action Level

 

 

 

1. Exceedance for one sample

1.  Repeat in-situ measurement to confirm findings.

2. Identify the source(s) of impact (e.g. intake water).

3. Inform HKITP and IEC.

4. Check monitoring data, all monitoring equipment and monitoring methods; consider changes of monitoring methods.

5. Discuss mitigation measures with HKITP and IEC.

6.  Repeat measurement on next day of exceedance.

1.     Discuss with IEC and ETL on WRC operations or any changes to the operations that may have an impact on the water quality.

2. Rectify unacceptable practice and propose mitigation measures.

3.     Make agreement on the mitigation measures to be implemented.

4. Implement the agreed mitigation measures.

1.   Discuss with ETL and HKITP on WRC operations or any changes to the operations that may have an impact on the water quality, and discuss possible mitigation measures.

2.   Review proposals on mitigation measures by HKITP.

3.   Assess the effectiveness of the implemented mitigation measures.

2. Exceedance for two or more consecutive samples

1.  Repeat in-situ measurement to confirm findings.

2.  Identify the source(s) of impact (eg intake water).

3. Inform HKITP and IEC.

4. Check monitoring data, all monitoring equipment and monitoring methods; consider changes of monitoring methods

5. Discuss mitigation measures with HKITP and IEC.

6.  Ensure mitigation measures are implemented.

7.  Prepare to increase monitoring frequency to assess efficacy of remedial measures.

8.  Repeat measurement on next day of exceedance.

 

1.     Discuss with IEC and ETL on WRC operations or any changes to the operations that may have an impact on the water quality.

2. Rectify unacceptable practice and propose mitigation measures.
