Summary of
Exceedance of the Environmental Quality Performance Limit
4.1.1
Summary of Action and Limit Level exceedance of
1-hr TSP level and 24-hr TSP level at AMS6 is reported in the monthly EM&A
Reports prepared by Contract No. HY/2011/03 (from September 2015 to January
2019).
4.1.2
There
was one Action Level exceedance of 24-hr TSP level recorded at station AMS3B by
the Environmental Team of Contract No. HY/2013/01 on 28 November 2017, one
Action Level exceedance of 24-hr TSP level recorded at station AMS3B by the
Environmental Team of Contract No. HY/2013/01 on 23 December 2017, and two
Action Level exceedances of 24-hr TSP level recorded at station AMS2 and AMS3B
by the Environmental Team of Contract No. HY/2013/01 on 17 January 2018 during
the reporting period. After investigation, it was concluded that all
exceedances were not relevant to Contract No. HY/2013/03.
4.1.3
There was no Action and Limit Level exceedance of
1-hr TSP level and 24-hr TSP level recorded on other monitoring dates at
station AMS2, AMS3B/AMS3C and AMS7/AMS7A/AMS7B by the Environmental Team of Contract
No. HY/2010/02 (from September 2015 to August 2017), Contract No. HY/2013/01
(from September 2017 to September 2018), and Contract No. HY/2013/04 (from
October 2018 to January 2019). Although the exceedances were not relevant to Contract
No. HY/2013/03, the Contractor was reminded to continue to fully maintain all
air quality mitigation measures and prevent any air quality impact.
4.1.4
There was no Action and Limit Level exceedance for
noise recorded at station NMS2 and station NMS3B/NMS3C by the Environmental
Team of Contract No. HY/2010/02 (from September 2015 to August 2017), Contract
No. HY/2013/01 (from September 2017 to September 2018), and Contract No.
HY/2013/04 (from October 2018 to January 2019) during the reporting period.
4.1.5
There were Action and Limit Level exceedances
recorded at different WQM stations recorded on 90 days during the reporting
period. The following table
summarized the number of exceedance on each sampling date:
