NOISE
3.1.1
In
accordance with the Contract Specific EM&A Manuals, Leq
(30min) monitoring is conducted for at least once a week during the construction
phase between 0700 and 1900 on normal weekdays at the designated monitoring
locations.
3.1.2
According
to the EPD’s reply email, EPD has no comment on the Proposal for Termination of
Air quality and Noise Monitoring, the noise monitoring for Contract No:
HY/2019/01 have been terminated on 25 March 2022. The last monitoring was
completed on 24 March 2022.

Monitoring Parameters and Frequency
3.2.1
The parameters and frequencies of impact noise monitoring is
summarized in Table 3.1.
3.3
Monitoring Locations
3.3.1
In
accordance with the Contract Specific EM&A Manual, two noise monitoring
locations, namely NMS2 and NMS3C are covered under Contract No. HY/2019/01
“Hong Kong-Zhuhai-Macao Bridge Hong Kong Boundary Crossing Facilities – Phase 2
and Other Works.
3.3.2
Due
to rejection from Ho Yu College (NMS3) for setting up a noise monitoring
station at their school, an alternative location at site boundary of the site
office area at Works Area WA2 (NMS3B) is proposed. Impact noise monitoring has
been relocated from NMS3B to Ying Tung Estate Market Rooftop (NMS3C) on 20
August 2018 under Contract No. HY/2013/04. The same baseline and Action and
Limit levels for noise, as derived from the baseline monitoring data recorded
at Ho Yu College, are adopted for this alternative noise monitoring location.
3.3.3
The
most updated locations are summarized in Table 3.2 and the locations of the noise
monitoring stations shown in Figure
