ENVIRONMENTAL MONITORING AND AUDIT
13.1.1
The development of appropriate environmental monitoring and audit
(EM&A) programmes and methodologies are a vital part of the environmental
management and control of the Project.
This chapter provides an outline of the EM&A requirements for the
Project, highlighting the environmental parameters to be monitored, timing of
the monitoring work and the frequency of the monitoring and audit work. A detailed scope of work will be provided in
the EM&A Manual, prepared in accordance with Annex 21 of the TMEIA and
EPD’s EM&A Guidelines for Development
Projects in Hong Kong.
13.1.2
The broad objectives of the monitoring and audit process are:
(i) to clarify and identify sources of
pollution, impact and nuisance arising from the works;
(ii) to establish a record of change
associated with the implementation of a project;
(iii) to verify all or selected parameters
measured are in compliance with legal and contract specifications, internal
policies and standards;
(iv) to provide an early warning system for
impact prevention;
(v) to provide a database of environmental
parameters against which to determine any short term or long term environmental
impacts;
(vi) to propose timely, cost-effective and viable
solutions to actual or potential environmental issues;
(vii) to setup event and action plans and
determine the degree and scope of any necessary remedial measures in
case of exceedance of compliance, for which environmental monitoring forms the
basis, or the recommendation of environmental controls in the event that the
environmental objectives are not achieved;
(viii) to monitor performance of the mitigation
measures and to assess their effectiveness and, whenever necessary, identify
any further need for additional measures;
(ix) to verify the EIA predicted impacts and
compare the impact predictions with actual impacts for the purpose of assessing
accuracy of impact predictions in EIA;
(x) to collate information and evidence for
use in public and Government consultation; and
(xi) to audit the environmental performance.
13.2.1
In
accordance with the EIA, EM&A procedures
are required during the design, construction and operational phases of the
project implementation and a summary of the requirements for each of the
environmental parameters is detailed in Table 13.1 below.

13.2.2
The EM&A works during the design phase shall
comprise an iterative audit process of specific design elements by a suitably
qualified auditor(s). The
specifications for certain ecological and landscape mitigation measures
recommended by the EIA will be required to be designed during the detailed
design phase of the project. These
items will include:
¨
transplantation
of the shrub Pavetta
hongkongensis, orchids Acampe rigida and Liparis
viridiflora and tree Artocarpus hypargyreus;
¨
special
design of new culverts and culvert inlet and outlets for streams 19 and 21
(Figure 6.1) and culvert inlet and outlets for Stream
18;
¨
translocation
of Hong Kong Newt, Lesser Spiny Frog and Romer’s Tree Frog from streams 15, 18,
19 and 21;
¨
scheduling
of works in streams 15, 18, 19 and 21 to avoid the period April to June which
is the key breeding period for fish, amphibians
and odonates;
¨
translocation
of Romer’s Tree Frog between Lung Tseng Tau and Shek Mun Kap;
¨
provision
of water filled pots as habitats for the Romer's Tree Frog between Lung Tseng
Tau and Shek Mun Kap;
¨
translocation
of isolated population of Beijiang Thick-lipped Barb in
Stream 15 to tributary of Tung Chung Stream;
¨
provision
of slope surfaces at step channels for aquatic fauna to move up and down stream
at the existing bridge at stream 15;
¨
provision
of escape routes from drainage channels for amphibians;
¨
provision
of wildlife tunnels for faunal transfer; and
¨
landscape
design drawings.
13.2.3
The design audit shall be undertaken as and when the relevant
design aspects are produced and the Consultant will be required to prepare a
Design Audit Report at the end of the detailed design which will confirm that the
requirements of the EIA have been fully taken into account in the project
design.
13.2.4
During the construction and operational phases, the EM&A
requirements are divided into environmental monitoring and/or project auditing
in the form of site inspection and supervision. The environmental monitoring will be conducted in three distinct
stages, as follows:
(i)
baseline (pre-construction);
(ii) construction phase impact; and
(iii) operational phase impact.
13.2.5
Environmental monitoring and audit for dust, noise and water
quality during the construction phase is recommended in order to ensure all
proposed mitigation measures are implemented and effective. Obtaining a suitable and representative
baseline data set will be critical to the whole monitoring and audit process
because it forms the standard against which environmental impacts are
assessed. Thus, baseline monitoring for
dust, noise and water quality will be required prior to the start of
construction. All three of these
parameters will also be subject to audit through site supervision.
13.2.6
Site supervision and procedures audit will be required during the
construction phase to ensure the proper handling, storage, transportation and
disposal of the various waste arisings from the project.
13.2.7
Audit of the implementation of the design elements and mitigation
measures to avoid ecological and landscape and visual impacts have also been
recommended by the EIA, and thus, monitoring in the form of regular site
inspections shall also be required to ensure mitigation measures are being
implemented and are effective. EM&A
for both ecology and landscape and visual resources will extend through the
construction phase and into the operational phase to ensure landscape and
ecological planting/replanting have been effective.
13.2.8
Operational noise monitoring shall be undertaken during the first
year of the operation of the project to assess the effectiveness of the direct
noise mitigation measures recommended by the EIA.
13.2.9
The details of monitoring are discussed in the following sections
and summarised in Table 13.2 below.

13.3.1.1 Noise surveys
will collect L10, L90, and Leq parameters as
shown in Table 13.2 prior to the start of construction at strategic noise
sensitive receivers. The designated monitoring locations are detailed in the
EM&A Manual.
13.3.2.1 Dust surveys
will consist of a daily 24 hour sampling for two weeks and one hour sampling
three times per day at representative sensitive receivers as shown in Table
13.2. The designated monitoring
locations are detailed in the EM&A Manual.
13.3.3.1 Ecology surveys
will consist of a walk-over survey prior to construction works. It may be necessary to rope off and protect
specific habitats or species of special interest identified during the
ecological surveys. Works around
ecologically sensitive streams and rivers will require particular attention.
13.3.4.1 Baseline water
quality monitoring of the streams in the study area will be carried out 4 days
per week for a period of 4 weeks to measure suspended solids, turbidity,
dissolved oxygen and pH at all monitoring stations. A walkover survey of watercourses within the study area will also
be undertaken, including Tung Chung and Cheung Sha Streams and their
tributaries, to note and photograph the visual conditions of the water
bodies.
13.3.5
Landscape/Visual Resources
13.3.5.1 Baseline monitoring for
landscape will comprise a vegetation survey of the entire selected route option undertaken on an ‘area’
basis. Representative vegetation types
will be identified along with typical species composition. An assessment of landscape character will be
made against which future change can be monitored. The landscape resources and
elements of particular concern are to be noted. Reference shall be made to the Tree Survey Report to the EIA and
the habitat maps included in the EIA.
13.3.6.1 Baseline monitoring for the cultural
heritage resources will comprise a walkover survey of the shrine in Lung Tseng
Tau and the Fong Yuen Nunnery to determine the existing baseline condition
prior to construction.
13.4
Construction

13.4.1
Action and Limit Levels
13.4.1.1 Monitoring
stations will be set up at representative sensitive receivers and the results
will be used to ensure compliance with determined performance criteria, based
upon specific action and limit levels. The definition of these are as follows:
¨
the Action Level represents a level at
which some appropriate action will be required to prevent conditions
deteriorating to the extent that statutory or guide criteria are breached; and
¨
the Limit Level represents the upper limit
permitted and is generally equivalent to the statutory levels specified in
legislation.
13.4.1.2 The construction
phase monitoring and relevant audit criteria for noise, dust and water quality
are highlighted below. Action plans
will be developed for use in the event of exceedances, or non conformities in
the case of ecology, landscape and visual and waste, and these will be included
in the EM&A Manual.
13.4.1.3 Action plans and
audit criteria are not relevant to the ecology, waste, landscape and visual and
cultural heritage EM&A. However,
the supervision methodology is highlighted below.
13.4.2.1 The construction
noise level will be measured in terms of the A-weighted equivalent continuous
sound pressure level (Leq).
Leq measurements will be taken during 30 minutes of typical
construction activity during unrestricted periods. For all other time periods,
the average of three consecutive Leq(5
min) results will be taken for comparison with the Noise Control
Ordinance (NCO) criteria. As supplementary information for data auditing and
statistical analysis, parameters including Leq, L10 and L90
will also be obtained for reference.
13.4.2.2 Sound level
metres in compliance with the International Electrotechnical Commission
Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications will be
used for carrying out the noise monitoring, in accordance with the Technical
Memorandum (TM) issued under the NCO.
The noise measurements shall be carried out 1m from the worst-affected
external facades of the representative NSRs, or 1.2m above the ground in the case
of the measurement not being carried out at a building and shall not be made in
the presence of fog, rain or excessive steady or gusty wind.
13.4.2.3 The monitoring
will be undertaken at representative noise monitoring locations once per 6 days
and action and limit levels for work during the unrestricted period and
restricted periods for reference are shown in Table 13.3.

13.4.3.1 Monitoring and
audit of the Total Suspended Particulates (TSP) levels shall be carried out to
detect any deterioration in air quality and so enable early action to be taken
for impact prevention or amelioration. Both 1-hour and 24-hour TSP levels shall
be measured to indicate the impacts of construction dust on air quality using a
direct reading dust monitor and high volume sampler respectively. Both the 24 hour TSP levels and 1-hour TSP
levels shall be measured in accordance with the standard high volume sampling
method as set out in the Title 40 of the Code of Federal Regulations, Chapter 1
(Part 50), Appendix B. Direct reading
methods can be used for ad hoc measurements if required. Other relevant data that will need to be
recorded will include elapsed-time metre reading for the start and stop of the
sampler, the prevailing weather conditions, namely wind speed and direction,
temperature, pressure and rainfall.
13.4.3.2 The sampling
frequency will be at least once in every six-days for 24-hour TSP monitoring
and at least three times in every six days for 1-hour TSP. Action and limit levels are shown in Table
13.4.

13.4.4.1 Surveys are to
be undertaken for watercourses which are within the influence of construction
works at least twice per week. The surveys should include a description of the
stream course, influencing factors, photographs of the watercourse and a map
showing areas of project construction works. In addition measurements of
suspended solids, dissolved oxygen and pH should be taken at all monitoring
stations at least three times per week and also in-situ measurements taken
daily at strategic locations, as specified in the EM&A Manual. In association with the water quality
parameter, some relevant data shall also be measured, such as monitoring location/position,
time, water depth, water temperature, DO saturation, weather conditions, and
any special phenomena and work underway at the construction site etc.
13.4.4.2 Any noticeable
change to water quality should be recorded in the watercourse survey reports
and should be investigated and remedial actions shall be undertaken to reduce
impacts. Particular attention shall be paid to the Contractor’s incorporation
of mitigation measures. Action and limit levels proposed for the water quality
parameters to be measured are shown in Table 13.5.

Notes:
- For DO, non-compliance of the water quality
limits occurs when monitoring result is lower than the limits.
- For SS, non-compliance of the water quality
limits occurs when monitoring result is
higher than the limits.
- All the figures given in the table are used
for reference only and the DEP may amend the figures whenever it is considered
necessary.
- ‘Depth Averaged’ is calculated by taking the
arithmetic mean of the in-situ parameters readings at all three depths. For suspended solids ‘depth averaged’ is
calculated by combining all three samples into one mixed sample which is
analysed to produce a physical arithmetic mean.
13.4.5.1 Walk-over
ecology surveys are to be undertaken twice a month in areas which are disturbed
by the construction works. The surveys shall include a report on ecological disturbances
to the area and corrective measures should be recommended.
13.4.5.2 Of concern
during the early years of operation will be erosion of recently revegetated cut
and fill slopes. These should be monitored visually and especially following
storms. Any corrective measures should
be recommended.
13.4.5.3 Success of
replanting should be monitored by regular visual inspections and special care
should be taken to ensure than any damaged, diseased or dying trees or shrubs
are replaced as required. A detailed programme of visits should be agreed prior
to commencement of the contracts and should be at least once every two months
for a period of a year during the maintenance period.
13.4.5.4 For specific
ecological mitigation measures, the audit schedule as detailed in Table 13.6
shall be followed.

13.4.6.1 The landscape
construction works will be closely monitored to ensure all measures specified
to promote the healthy establishment of plants are undertaken fully and that
any defects or omissions are rectified at the earliest opportunity and before
the end of the construction period.
13.4.6.2 The protection
provided to all trees and woodland blocks identified will be monitored
throughout the construction period to ensure that it is kept in a good
condition. Any damage by the Contractor
or by other parties to the protection of the trees and woodland will be noted
for remedial action.
13.4.6.3 The extent of
the agreed works areas will be regularly checked during the construction
phase. Any trespass by the Contractor
outside the limit of the works, including any damage to existing trees and

13.4.6.4 Operations relating to the supply of specialist plant material
(including the collecting, germination and growth of plants from seed) will be
monitored to ensure that plants will be available in time to be used within the
construction works.
13.4.6.5 The progress of the
engineering works will be regularly reviewed on site to identify the earliest
opportunities for the landscape works to be undertaken.
13.4.7.1 Supervision of
the construction works should be undertaken on a weekly basis during site inspections to ensure that waste material is being properly stockpiled
and handled. Any malpractice should be
reported and remedial measures recommended.
Review of the waste documents shall be undertaken on a weekly basis to
ensure waste management is being undertaken in accordance with the Waste
Management Plan.
13.4.8.1 Supervision of
the construction works should be undertaken twice a month for the shrine in
Lung Tseng Tau and the Fong Yuen Nunnery.
The surveys will audit the implementation of the recommended mitigation
measures in these areas, namely the creation of a protective barrier around the
shrine if it falls within the works area, maintenance of the 50 metre wooded
buffer between the road and the nunnery, planting of foliage along the cycle path in the
vicinity of the monastery and fence of the main building to keep it separate from the
works on the cycle path. Any disturbances to these areas will be reported and
corrective measures should be recommended to ensure that both buildings are
adequately protected during works.

13.5.1
Post construction monitoring is limited to monitoring of noise,
ecology and landscaping to ensure the recovery of habitats and plantings and
ensure the effectiveness of noise mitigation measures. Site inspections for ecological and
landscape and visual resources shall be undertaken once every two months for
the first year of operation. For specific ecological mitigation measures, the
audit schedule as detailed in Table 13.7 shall be followed.

6 and 12. Any three 30 minute periods
during the week day peak times shall be monitored.
13.6.1
In respect of the design phase EM&A, the Consultant commissioned
to undertake the Design and Construct contract will be required to designate an
auditor(s) to undertake an environmental audit of the design of these measures
in order to ensure that the recommendations of the EIA have been fully and
properly specified. The design audit
shall be undertaken as and when the relevant design aspects are produced. The Consultant shall use suitably qualified
staff to undertake the audit requirements to the satisfaction of the EPD, the
AFCD and the PlanD/LPU as appropriate.
13.6.2
During the construction and operational phases of the project, an
Environmental Specialist (ES) is to be employed by the Contractor. He shall ensure the Contractor’s compliance
with the project’s environmental performance requirements during construction
and undertake the post construction EM&A works and his responsibilities
will include field measurements, sampling, analysis of monitoring results,
reporting and auditing. The ES shall be
approved by the ER and the Director of Environmental Protection (DEP) and shall
be competent and shall have at least 7 years relevant environmental monitoring
and audit experience on projects of a similar scale and nature.
13.6.3
The ES will require suitably qualified support staff (the
Environmental Team, (ET)) to carrying out the EM&A programme. Both the ES and members of the ET shall be
independent and shall not be in any way connected to the Contractor’s
company. Due to the specialist nature
of some of the EM&A works required for this project, the ET should comprise
professionals proficient to undertake the tasks involved. Thus, the ET should include personnel
experienced in noise, dust and water quality monitoring and supervision of
waste management.
13.6.4
Accordingly, a qualified ecologist(s), with a minimum of 5 years
post qualification experience and two years practical experience in ecological
remediation and relocation works, will be required as part of the ET to audit
the transplantation of key species as recommended by the EIA. The ecologist(s) should have suitable experience
in the areas to be audited. In
addition, a Registered Landscape Architect, as defined by the Landscape
Architect’s Registration Board, will be required on the ET to monitor and audit
the landscaping installation works and assist in the audit of the ecological
transplantation and restoration works.
13.6.5
In respect of the archaeological supervision, these works should
be undertaken by a suitably qualified person to the acceptability of the
AMO. The responsibilities of the
specialist will be to oversee the construction activities, notify the AMO, EPD
and the ER of any findings and develop appropriate mitigation measures.
13.6.6
In addition to the ES, an Independent Checker (Environment)
(IC(E)) shall be resident on site to advise the ER on environmental issues
related to the project. The role of the
Checker shall be independent from the management of construction works, but the
Checker shall be empowered to audit the environmental performance of the
construction activities and operational mitigation. The IC(E) shall have project management experience in addition to
the requirements of the ES specified in Section 13.6.2 and the appointment of
the IC(E) will be subject to the approval of the ER and the DEP. The IC(E) may require specialist support
staff in order to properly carry out his duties.
13.7.1
Deliverables during the design phase will comprise a Design Audit
Report at the end of the detailed design which will confirm that the
requirements of the EIA have been fully taken into account in the project
design. Construction and operational
reporting will be in the form of the baseline survey report and regular and
summary EM&A Reports which should be prepared in accordance with the
requirements of Annex 21 of the TMEIA.
It is recommended that EM&A Reports are issued monthly and
bi-monthly for the construction and operational stages respectively. Further details on the contents of these
