executive summary

ES.01      CRBC-Kaden Joint Venture (hereafter “CRBC-Kaden JV”) has been awarded by Highways Department as the Main Contractor for the Contract HY/2013/12 - Northern Connection Toll Plaza and Associated Works (hereinafter referred as “the Contract”) in July 2014.  This is a Designated Project to be implemented under Environmental Permit number EP-354/2009/D (hereinafter referred as “the EP”).

 

ES.02      Action-United Environmental Services & Consulting (hereinafter referred as “AUES”) has been commissioned as the Contract Environmental Team (hereinafter referred as “the ET”) to implement the relevant EM&A program in accordance with the approved EM&A Manual and the Contract requirements, as well as the associated duties. 

 

ES.03      According to the Approved EM&A Manual, baseline environmental monitoring is required to be conducted prior to commencement of the construction works.  As such, baseline monitoring including air quality, ecology, landscape and visual and cultural heritage was conducted.  During the baseline monitoring period, no construction activities under the Project or other external influencing factors of significant concern were observed.

 

ES.04      Baseline air quality monitoring was conducted by the ET of HyD Contract HY/2012/08 between 17 and 31 October 2013.  The monitoring results and established Action and Limit Level for 1-hour TSP and 24-hour TSP would be adopted for this Contract.

 

ES.05      Baseline survey for Pitcher Plant has been conducted within the project area in September 2013 by a suitably qualified ecologist.  During the survey, 280 nos. of individual were identified which were in good condition.  Moreover, an initial survey for Pitcher Plant by the Contract HY/2013/12 was conducted in mid-September 2014 to confirm the number of existing Pitcher Plant.  A total of 280 nos. of individual Pitcher Plant located at Zone 1 to 7 was identified.  Since they are occurring on the rocky slope habitat which will be impacted by the proposed slope works (Zone 1 to 7), transplantation is required to minimize impacts to the population. 

 

ES.06      Initial tree survey and photographic record for existing Landscape was conducted on 22 September 2014 for TM-CLKL prior commencement of the project.

 

ES.07      Condition survey for the Grave G1 was conducted on 23 September 2014.  The grave was generally in good condition.  However, a total of 10 cracks ranged from hairline to 2.8mm were identified in the cement rendering and mortar of bricks of the grave.

2.4                            Monitoring Methodology

24-hour TSP

 

Instrumentation

2.4.1.1                High volume Samplers (HVS) completed with appropriate sampling inlets were employed for air quality monitoring. Each sampler was composed of a motor, a filter holder, a flow controller and a sampling inlet and its performance specification complies with that required by USEPA Standard Title 40, Code of Federation Regulations Chapter 1 (Part 50).

 

HVS Installation

2.4.1.2                The following guidelines were adopted during the installation of HVS:

Ÿ   Sufficient support was provided to secure the samplers against gusty wind.

Ÿ   No two samplers were placed less than 2 meters apart.

Ÿ   The distance between the sampler and an obstacle, such as buildings, was at least twice the height that the obstacle protrudes above the sampler.

Ÿ   A minimum of 2 meters of separation from walls, parapets and penthouses was required for rooftop samples.

Ÿ   A minimum of 2 meters separation from any supporting structure, measured horizontally was required.

Ÿ   No furnaces or incineration flues were nearby.

Ÿ   Airflow around the sampler was unrestricted.

The samplers were more than 20 meters from the drip line.

Ÿ   Any wire fence and gate, to protect the sampler, should not cause any obstruction during monitoring.

 

Filter Preparation

2.4.1.3                Fiberglass filters were used [Note: these filters have a collection efficiency of larger than 99% for particles of 0.3μm diameter]. A HOKLAS accredited laboratory was responsible for the preparation of 24-hr conditioned and preweighed filter papers for monitoring team.

 

2.4.1.4                All prepared filters were equilibrated in the conditioning environment for 24 hours before weighing. The conditioning environment temperature was around 25 °C and not variable by more than ±3 °C; the relative humidity (RH) was <50% and not variable by more than ±5%. A convenient working RH was 40%.

 

Operating/ Analytical Procedures

2.4.1.5                Operating/analytical procedures for the air quality monitoring were highlighted as follows:

Ÿ   Prior to the commencement of the dust sampling, the flow rate of the HVS was properly set (between 1.1 m3/min. and 1.4 m3/min.) in accordance with the manufacturer's instruction to within the range recommended in USEPA Standard Title 40, CFR Part 50.

Ÿ   The power supply was checked to ensure the sampler worked properly.

Ÿ   On sampling, the sampler was operated for 5 minutes to establish thermal equilibrium before placing any filter media at the designated air quality monitoring station.

Ÿ   The filter holding frame was then removed by loosening the four nuts and carefully a weighted and conditioned filter was centered with the stamped number upwards, on a supporting screen.

Ÿ   The filter was aligned on the screen so that the gasket formed an airtight seal on the outer edges of the filter. Then the filter holding frame was tightened to the filter holder with swing bolts. The applied pressure should be sufficient to avoid air leakage at the edges.

Ÿ   The shelter lid was closed and secured with the aluminum strip.

Ÿ   The timer was then programmed. Information was recorded on the record sheet, which included the starting time, the weather condition and the filter number (the initial weight of the filter paper can be found out by using the filter number).

Ÿ   After sampling, the filter was removed and sent to the laboratory for weighing. The elapsed time was also recorded.

Ÿ   Before weighing, all filters were equilibrated in a conditioning environment for 24 hours. The conditioning environment temperature should be between 25°C and 30°C and not vary by more than ±3°C; the relative humidity (RH) should be < 50% and not vary by more than ±5%. A convenient working RH is 40%. Weighing results were used for further analysis of TSP concentrations collected by each filter.

 

Maintenance and Calibration

2.4.1.6                The following maintenance/calibration was required for the HVS:

Ÿ   The high volume motors and their accessories were properly maintained. Appropriate maintenance such as routine motor brushes replacement and electrical wiring checking were made to ensure that the equipment and necessary power supply are in good working condition.

Ÿ   All HVS were calibrated (five point calibration) using Calibration Kit prior to the commencement of the baseline monitoring and thereafter at bi-monthly intervals.

 

1-hour TSP

 

Measuring Procedures

2.4.1.7                The measuring procedures of the 1-hour dust meter are in accordance with the Manufacturer’s Instruction Manual as follows:

Ÿ   The 1-hour dust meter is placed at least 1.3 meters above ground.

Ÿ   Set POWER to “ON” and make sure that the battery level was not flash or in low level.

Ÿ   Allow the instrument to stand for about 3 minutes and then the cap of the air sampling inlet has been released.

Ÿ   Push the knob at MEASURE position.

Ÿ   Set time/mode setting to [BG] by pushing the time setting switch. Then, start the background measurement by pushing the start/stop switch once. It will take 6 sec. to complete the background measurement.

Ÿ   Push the time setting switch to change the time setting display to [MANUAL] at the bottom left of the liquid crystal display. Finally, push the start/stop switch to stop the measuring after 1 hour sampling.

Ÿ   Information such as sampling date, time, count value and site condition were recorded during the monitoring period.

 

Maintenance and Calibration

2.4.1.8                The following maintenance/calibration is required for the 1-hour dust meter;

Ÿ   Check and calibrate the meter by HVS to check the validity and accuracy of the results measured by direct reading method at 2-month intervals throughout all stages of the air quality monitoring.

3                                  ECOLOGY

3.1                            Introduction

3.1.1.1                Ecological baseline EM&A will consist of undertaking the following:

Ÿ   a walk-over survey, prior to construction works, of the land and streams where works will be undertaken. It may be necessary to rope off and protect specific habitats or species of special interest identified during the ecological surveys

 

3.2                            Baseline Walkover Survey

3.2.1.1                The purpose of the walk over survey will be to confirm the existing ecological conditions, with reference to the habitat maps included in the EIA Report and the established baseline conditions, in relation to the extent and condition of the habitats and species noted during the walkover survey.  No detailed ecological surveys of flora and fauna will be required at this stage.

 

3.2.1.2                Baseline ecological walkover was conducted on 22 September 2014 and the results are presented in below.

 

Observations

 

3.2.1.3                Two major landscapes within the study area were tall shrubland and plantation according to the habitat map in the approved EIA Report.  To better record specific species of native trees and shrubland, a general record about their habit of growth was made.

 

Tall Shrubland

3.2.1.4                Shrubland habitat is densely populated with a mix native tree shrubby plant species within study area. Native tree like Acacia confuse as well as other shrubby plant species are planted broadly in this area. Shrublands are widely distributed. The most common one are the Acacia confusa, Leucaena leucocephala, Macaranga tanarius and Clausena lansium. They have mixed with each other and get better greening benefit.  No significant change to habitat maps in the EIA Report was observed.

 

Plantation

3.2.1.5                Plantation at the study area contain mainly roadside plantation for landscape use within the study area. The plantation part, trees, for instance, Ficus microcarpa and Ficus elastica are most widely used as roadside (riverside) plant and landscape greening. They are common evergreen trees in Hong Kong and can grow as tall as fifteen meters which are considered to be very aggressive. No significant change to habitat maps in the EIA Report was observed.

 

Stream

3.2.1.6                The outlet of the stream opposite to the River Trade Terminal is now modified to an artificial culvert. Other than that, the habitat types within the Study area are similar to the habitat maps in the EIA report.

 

Developed Area

3.2.1.7                The developed area such as warehouses and River Trade Terminal was observed.  No significant change to habitat maps in the EIA Report was observed.

 

Sandy beach

3.2.1.8                Part of the Butterfly Beach as designated in EIA, is located at the eastern side of the pillar point.  No significant change to habitat maps in the EIA Report was observed.

 

3.2.1.9                The habitat map of Tuen Mun is shown in Appendix B.

 

3.3                            Baseline Translocation Works - Pitcher Plant

3.3.1.1                During the Environmental Impact Assessment (EIA) Stage of the TM-CLKL (which was approved on 23 October 2009), no Pitcher Plant (Nepenthes mirabilis) was identified within the proposed works area of the toll plaza. It was believed that the Pitcher Plant area identified would not be directly impacted by the toll plaza works and the only mitigation measures required were to install hoarding at the perimeter of the proposed works area to avoid encroachment into the Pitcher Plant area. However, during an ecology survey for the TMWB EIA in late 2011, Pitcher Plant was identified within the proposed works area for the TM-CLKL toll plaza.  Pitcher Plant is protected under the Forestry Regulations (subsidiary legislation of the Forests and Countryside Ordinance, Cap. 96) and the Protection of Endangered Species of Animals and Plants Ordinance (Cap. 586). Discussion with Agriculture, Fisheries and Conservation Department (AFCD) (27 October 2012) has confirmed that if the TM-CLKL project was to impact the Pitcher Plant area that further mitigation measures for the Pitcher Plant would be required under the TM-CLKL project. As such, the project proponent Highways Department (HyD) has appointed AECOM to undertake baseline survey and propose a transplantation strategy for Pitcher Plant to be affected by the proposed TM-CLKL project. 

 

3.3.1.2                A baseline Pitcher Plant survey was conducted in September 2013 by a suitably qualified ecologist.  The aim of the survey was to update, identify and record the location, number, health condition (i.e. good, fair, or poor), and suitability for transplantation of the affected individuals in order to provide details for the transplantation exercise. Each identified individual was tagged. The habitats present and representative plant species were recorded.

 

3.3.1.3                The assessment area included the slope above the toll plaza on which the Pitcher Plant populations have been previously identified. The slope was surveyed to identify the extent of the Pitcher Plant populations particularly those that occur within and adjacent to the proposed works site.

 

Baseline Results on September 2013

 

3.3.1.4                The south-facing slope above the proposed toll plaza supports a mosaic of shrubland, rocky slope, plantation and watercourse habitats. Pitcher Plant was recorded in the rocky slope, shrubland and watercourse habitats. The rocky slope habitat comprised some exposed boulders and bare ground; however, much of it has been naturally regenerated by shrubland species such as Dichotomy Forked Fern (Dicranopteris pedata), with some encroachment by scattered Brisbane Box (Lophostemon confertus) saplings from the adjacent plantation habitat. This habitat supported a Pitcher Plant population (see Zones 1-7 in Appendix C) of approximately 0.5 ha in size and 259 Pitcher Plants (see Appendix C, Plates 1-3)).

 

3.3.1.5                In addition, three small areas (see Zones 8 – 10 in Appendix C) of Pitcher Plant were recorded along the watercourse in the shrubland habitat (see Appendix C, Plate 4). The watercourse comprised a narrow, shallow flow over bedrock with occasional small, very shallow pooled areas. There is evidence that part of the flow is being diverted for human use. Riparian vegetation comprised the shrubland habitat in which the watercourse flowed. Abundant tree/shrub species found in the shrubland habitat included Dwarf Mountain Pine (Baeckea frutescens), Pop-gun Seed (Bridelia tomentosa), Eurya spp., Hong Kong Gordonia (Gordonia axillaris), Pond Spice (Litsea glutinosa), Pines (Pinus spp.), Wild Coffee (Psychotria asiatica), Rose Myrtle (Rhodomyrtus tomentosa), Hedge Sageretia (Sageretia thea), and Brisbane Box (Lophostemon confertus). While the understorey was dominated by Dichotomy Forked Fern (Dicranopteris pedata), with frequent Greenbrier (Smilax china), and occasional Hainan Galangal (Alpinia hainanensis), Oriental Blechnum (Blechnum orientale), Bentham’s Rosewood (Dalbergia benthami), Dianella (Dianella ensifolia), and Chinese Silvergrass (Miscanthus sinensis).

 

3.3.1.6                The health and condition of the Pitcher Plant individuals was assessed and each plant was assessed, tagged and photographed by Pegasus Greenland Ltd.. All plants were assessed as being in “fair” health condition as summarized in Table 3.  As the plants mostly grew on rock faces with thin soils, the successful removal and transport of the existing individuals is likely to be challenging given the weak nature of the plant’s roots.

Baseline Results on September 2014

 

3.3.1.7                Before commencement of the construction of the Contract, the initial survey was conducted by Hong Kong Landscape in September 2014 to confirm the location and number of the affected Pitcher Plants by the proposed TM-CLKL project.  During the initial survey in September 2014, a total of 280 nos. of individual Pitcher Plant located at Zone 1 to 7 was identified.  They are occurring on the rocky slope habitat which will be impacted by the proposed slope works (Zone 1 to 7).  Each identified individual were tagged and photographed.  The location map of the pitcher plants is shown in Appendix C.

 

3.3.1.8                280 nos. of Pitcher Plants identified in the initial survey will require transplantation to minimize impacts to the population.  For those unaffected Pitcher Plant in Zone 8 to 10, fencing or other physical barriers will be erected for protection. 

 

3.3.1.9                A transplantation proposal for Pitcher Plant in Zone 1 to 7 was submitted to EPD and AFCD for agreement separately.

5                                  CULTURAL HERITAGE

5.1                            Introduction

5.1.1.1                The EIA has recommended that EM&A for cultural heritage resources is undertaken during construction phase of the project. Implementation of the mitigation measures recommended by the EIA will be monitored through the site audit programme.

 

5.2                            Baseline Monitoring

5.2.1.1                Prior to construction, a baseline survey of the grave G1 should be undertaken to establish the existing condition.

 

5.2.1.2                The purpose of the baseline condition survey was to record the existing condition of the grave and comprised the following task.

 

1.        Identification of grave near the Project Site;

2.        Carry out visual inspection for the condition survey;

3.        Record the existing condition and evaluation of structural integrity of the grave;

4.        Record the exact location of the grave prior to construction commencement. This information formed the baseline information for reference during construction phase;

5.        Submission of all records such as photographs, grave locations, all detected cracks, defects and damage, if any.

 

5.3                            Condition Survey Findings

5.3.1.1                The condition survey was conducted on 23 September 2014 and the finding area presented below.

 

5.3.1.2                The historical grave was identified during the EIA stage of the project and the location of the grave (G1) was shown in Figure 5.1.  It was observed that plenty of bushes was grown around the grave.  The general view of the grave was shown in Figure 5.2.


 

 

Figure 5.2  General View of the Grave G1

 

5.4                            Existing Condition

5.4.1.1                The Grave G1 is generally in good condition.  However, a total of 10 cracks ranged from hairline to 2.8mm were identified in the cement rendering and mortar of bricks of the grave.  The location of the cracks are shown in Figure 5.3.  Detailed information such as crack width and photographic record of the grave are summarized in Table 5.1.

5.5                            Event and Action Plan

5.5.1.1                All measures undertaken by the Contractor during the construction phase in the vicinity of the grave shall be audited by the Environmental Team (ET), on a regular basis to ensure compliance with the intended aims of the recommended mitigation measures. Site inspections should be undertaken at least once per week throughout the construction period adjacent to these properties. The main aim of the survey is prevention of any possible damage to the grave and to ensure that the proposed mitigation measures are implemented. The broad scope of the audit will involve supervision of the following:

Ÿ   non-contact effects of the engineering works, such as vibration from pneumatic drills which could cause damage, such as foundation or wall cracks and loosening of tiles or fixtures; and

Ÿ   contact between the historic structures and equipment and materials associated with the engineering works.

 

5.5.1.2                Specifically, the monitoring programme will entail the following tasks:

Ÿ   the extent of the agreed works areas should be regularly checked during the construction phase to ensure the buffer with a minimum of 1.0m set back of the permanent structure and a minimum of 0.7m clearance from the grave, can be maintained during construction, and

Ÿ   ensure no stockpiling or equipment storage is affecting the structures.

 

5.5.1.3                In the event of non-compliance the responsibilities of the relevant parties is detailed in the Event /Action plan provided on Table 5.2.

6                                  COnclusions

6.1.1.1                The Baseline monitoring has been conducted prior commencement of the construction works of the project in accordance with the EM&A Manual of the TM-CLKL.  This Baseline Monitoring Report presents the baseline condition for air quality, ecology, landscape and visual and cultural heritage.

 

6.1.1.2                Baseline air quality monitoring was conducted by the ET of HyD Contract HY/2012/08 between 17 and 31 October 2013.  The monitoring results and established Action and Limit Level for 1-hour TSP and 24-hour TSP would be adopted for this Contract.

 

6.1.1.3                Baseline survey for Pitcher Plant has been conducted within the project area in September 2013 by a suitably qualified ecologist.  During the survey, a total of 280 nos. of individual were identified in Zones 1 to 10 which were in good condition.  Moreover, an initial survey for Pitcher Plant by the Contract HY/2013/12 was conducted in mid-September 2014 to confirm the number of existing Pitcher Plant.  A total of 280 nos. of individual Pitcher Plant located at Zone 1 to 7 was identified.  Since they are occurring on the rocky slope habitat which will be impacted by the proposed slope works (Zone 1 to 7), transplantation is required to minimize impacts to the population. 

 

6.1.1.4                Initial tree survey and photographic record for existing Landscape was conducted on 22 September 2014 for TM-CLKL prior commencement of the project.

 

6.1.1.5                Condition survey for the Grave G1 was conducted on 23 September 2014.  The grave was generally in good condition.  However, a total of 10 cracks ranged from hairline to 2.8mm were identified in the cement rendering and mortar of bricks of the grave.
