The objectives of carrying out the EM&A
include the following:
 |
To provide a database against
which short or long term environmental impacts of the
project can be determined; |
 |
To provide an early indication
should any of the environmental control measures or practices
fail to achieve the acceptable standards; |
 |
To monitor the performance
of the project and the effectiveness of mitigation measures; |
 |
To verify the environmental
impact predicted in the EIA studies; |
 |
To determine compliance
with regulatory requirements, standards and government
policies; |
 |
To take remedial action
if unexpected problems or unacceptable impacts arise;
and |
 |
To provide data to enable an environmental
audit |
Environmental Monitoring
Criteria
Assessment conducted
indicate that the CRIII works have the potential to generate
adverse air quality, noise, water quality, waste and landscape
and visual impacts during their construction. In order to
ensure that the impacts are reduced to acceptable levels a
number of mitigation measures have been recommended to be
implemented during the works. With these measures in place
assessments have shown that residual impacts will be acceptable.
Water Quality
Baseline monitoring for water quality is required to establish
ambient conditions prior to the commencement of works and
to demonstrate the suitability of the proposed impact, control
and reference monitoring stations. Monitoring shall take place
for 4 weeks prior to the commencement of marine works.
During the course of marine works, impact monitoring shall
be undertaken at the designated monitoring stations at a frequency
of 3 days per week, at both mid-ebb and mid-flood tides.
Noise
Baseline monitoring for noise shall
be carried out at designated monitoring stations over a continuous
period of at least two weeks in order to establish ambient
conditions prior to the commencement of any construction works.
There shall not be any construction activities in the vicinity
of the monitoring stations during the baseline monitoring.
Impact monitoring shall be carried out by taking continuous
24-hour noise measurements during the duration of the project.
General construction work carried out during restricted hours
shall comply with the conditions of a construction noise permit.
Air Quality
Baseline monitoring for air quality
shall be carried out at designated monitoring stations for
both 1-hour and 24-hour TSP prior to the commencement of any
construction work to establish ambient conditions. 24-hour
monitoring shall be carried out on consecutive days for a
period of no less than 14 days. 1-hour sampling shall be conducted
at least 3 times per day when the highest dust impact is expected,
over these same 14 days.
During construction activities, 24-hour TSP sampling shall
be conducted at designated monitoring stations at a frequency
of at least once every 6 days, when the highest dust impact
is expected and one hour sampling shall be undertaken three
times per week.
Solid Waste
A comprehensive waste management plan shall be set up at the
commencement of the Project and periodically audited to determine
whether the waste is being effectively managed. These audits
shall be conducted against approved procedures with review
on all aspects of waste management including waste generation,
storage, recycling, treatment, transport and disposal. A waste
management audit shall be conducted at the commencement of
construction works and quarterly thereafter.
Landscape and Visual
Monitoring and audit of landscaping works will to a large
extent be conducted through site inspections to ensure that
the works are implemented in accordance with specifications.
Results of visual inspections would be reported in monthly
audit reports.
Monitoring and audit work will be
undertaken by designated environmental team and independent
checker.
