3 Air Quality Monitoring Results

Monitoring Parameters

The impact monitoring had been carried out in accordance with section 5.8 of the approved EM&A Manual to determine the 1-hour and 24-hour total suspended particulates (TSP) levels at the monitoring locations in the reporting month.

The sampling frequency of at least once in every 6 days, shall be strictly observed at the monitoring stations for 24-hour TSP monitoring. For 1-hour TSP monitoring, the sampling frequency of at least 3 times in every 6 days should be undertaken when the highest dust impact occurs.

General meteorological conditions (wind speed, direction and precipitation) and notes regarding any significant adjacent dust producing sources had also been recorded throughout the impact monitoring period.

Monitoring Equipment

1-hour TSP levels and 24-hour TSP had been measured with direct reading dust meter and High-Volume Samplers respectively. It has been demonstrated its capability in achieving comparable results with high volume sampling method as set out in the Title 40 of the Code of Federal Regulations, Chapter 1 (Part 50).

The 1-hour TSP meter was calibrated by the manufacturer prior to purchasing. Zero response of the instrument was checked before and after each monitoring event. Operation of the 1-hour TSP meter followed manufacturer’s Operation and Service Manual. The 24-hour TSP meter was calibrated against firmware 80570-8100-V1.0.4, annually. Operation of the 24-hour TSP meter followed manufacturer’s Operation and Service Manual. Valid calibration certificate of dust monitoring equipment is attached in Appendix H.

A summary of the equipment that was deployed for the 24- hour averaged monitoring is shown in Table 3.1. The TSP monitoring was conducted as per the schedule presented in Appendix G.

The equipment used for 1-hour TSP and 24-hour TSP measurement and calibration are summarised in Table 3.1.

Table 3.1        Construction Dust Monitoring Equipment

Monitoring Parameter	Monitoring Equipment	Serial Number	Date of Calibration
1-hour TSP	LD-5R Digital Dust Indicator	761172	28 November 2023
24-hour TSP	TE-5170X High Volume Sampler	1049	31 May 2024
			17 June 2024
	TE-5028A Calibration Kit	3465	15 January 2024

Monitoring Methodology and QA/QC results

The 1-hour TSP monitor, portable dust meters (Sibata Digital Dust Indicator Model LD-5R) was used for the impact monitoring.  The 1-hour TSP meters provides a real time 1-hour TSP measurement based on 90^o light scattering. Three 1-hour TSP level were logged per every six days.

The 24-hour TSP monitor, High Volume Samplers (Tisch TE-5170x High Volume Air Sampler) were used for the impact monitoring. The 24-hour TSP monitoring consists of the following:

u The HVS was set at the monitoring location, with electricity supply connected and secured;

u HVS was calibrated before commencing the 1st measurement;

u The filter paper was weight and provided by HOKLAS lab (Acumen Laboratory and Testing Limited and ALS Technichem (HK) Pty Ltd) before and after the sampling. Certificate of HOKLAS accredited laboratory can be referred to Appendix I;

u The airflow over time during sampling process was recorded by the HVS.

HVSs were free-standing with no obstruction. The following criteria were considered in the installation of the HVS:

u Appropriate support to secure the samples against gusty wind needed to be provided the monitoring station;

u A minimum of 2m separation from walls, parapets and penthouses was required for rooftop samplers;

u No furnace or incinerator flues was nearby;

u Airflow around the sampler was unrestricted; and

u Permission could be obtained to set up the samplers and gain access to the monitoring station.

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

u A secured supply of electricity is needed to operate the samplers.

Preparation of Filter Papers:

u Glass fiber filters were labelled and sufficient filters that were clean and without pinholes were selected;

u All filters were equilibrated in the conditioning environment for 24 hours before weighing. The conditioning environment temperature was around 25℃ and not varied by more than ±3℃; the relative humidity (RH)was 40%; and

u Acumen Laboratory and Testing Limited and ALS Technichem (HK) Pty Limited, as HOKLAS accredited laboratory, implemented comprehensive quality assurance and quality control programmes on the filters.

Field Monitoring:

u The power supply was checked to ensure that the HVS was working properly;

u The filter holder and area surrounding the filter were cleaned;

u The filter holder was removed by loosening the foul bolts and a new filter, with stamped number upward, on a supporting screen was aligned carefully;

u The filter was properly aligned on the screen so that the gasket formed an airtight seal on the outer edges of the filter;

u The swing bolts were fastened to hold the filter holder down to the frame. The pressure applied should be sufficient to avoid air leakage at the edges;

u The shelter lid was closed and secured with an aluminum strip;

u The HVS was warmed- up for about 5 minutes to establish run- temperature conditions;

u A new flow rate record sheet was inserted into the flow recorder;

u The flow rates of the HVS was checked and adjusted to between 1.13-1.19 m3min-1, which was within the range specified in the EM&A Manual (i.e. 0.6- 1.7 m3min-1);

u The programmable timer was set for a sampling period of 24 hours ±hour, and the starting time, weather condition and filter number were recorded;

u The initial elapsed time was recorded;

u At the end of sampling, the sampled filter was removed carefully and folded in half so that only surfaces with collected particulate matter were in contact;

u The filter paper was placed in a clean plastic envelope and sealed; all monitoring information was recorded on a standard data sheet and

u The filters were sent to (Acumen Laboratory and Testing Ltd) for analysis.

Maintenance and Calibration:

u The HVS and their accessories were maintained in a good working condition. For example, motor brushes were replaced routinely and electrical wiring was checked to ensure a continuous power supply; and

u The flow rate of each HVS with mass flow controller was calibrated using an orifice calibrator, Initial calibrations of the dust monitoring equipment were conducted upon installation and prior to commissioning. Five-point calibration was carried out for HVS using TE-5025A Calibration Kit and TE-5028A Calibration KIT. HVS is calibrated in fortnightly Intervals. The calibration records for the HVS is given in Appendix H.

Wind Data Monitoring:

u The wind speed has been recorded from Hong Kong Observatory- King’s Park meteorological station, along with portable wind speed meter stand by as back up if malfunction occurred or data was not recorded from HKO.

Monitoring Locations

As informed by the Contractor, the Hong Kong International Trade and Exhibition Centre will undergo redevelopment in 2024. The original air monitoring station (E-A1) is no longer available.

Water Quality (Construction Phase)

S6.9.1.1

W1

In accordance with the Practice Note for Professional Persons on Construction Site Drainage, Environmental Protection Department, 1994 (ProPECC PN1/94), construction phase mitigation measures shall include the following:

Construction Runoff

· At the start of site establishment, perimeter cut-off drains to direct off-site water around the site should be constructed with internal drainage works and erosion and sedimentation control facilities implemented.  Channels (both temporary and permanent drainage pipes and culverts), earth bunds or sandbag barriers should be provided on site to direct stormwater to silt removal facilities.  The design of the temporary on-site drainage system will be undertaken by the contractor prior to the commencement of construction;

· The dikes or embankments for flood protection should be implemented around the boundaries of earthwork areas.  Temporary ditches should be provided to facilitate the runoff discharge into an appropriate watercourse, through a silt/ sediment trap.  The sediment/ silt traps should be incorporated in the permanent drainage channels to enhance deposition rates;

· The design of efficient silt removal facilities should be based on the guidelines in Appendix A1 of ProPECC PN 1/94, which states that the retention time for silt/ sand traps should be 5 minutes under maximum flow conditions.  Sizes may vary depending upon the flow rate, but for a flow rate of 0.1 m3/s a sedimentation basin of 30 m3 would be required and for a flow rate of 0.5 m3/s the basin would be 150 m3.  The detailed design of the sand/ silt traps shall be undertaken by the contractor prior to the commencement of construction;  

· All exposed earth areas should be completed and vegetated as soon as possible after earthworks have been completed, or alternatively, within 14 days of the cessation of earthworks where practicable.  Exposed slope surfaces should be covered by tarpaulin or other means;

· The overall slope of the site should be kept to a minimum to reduce the erosive potential of surface water flows, and all traffic areas and access roads protected by coarse stone ballast.  An additional advantage accruing from the use of crushed stone is the positive traction gained during prolonged periods of inclement weather and the reduction of surface sheet flows;

· All drainage facilities and erosion and sediment control structures should be regularly inspected and maintained to ensure proper and efficient operation at all times and particularly following rainstorms.  Deposited silt and grit should be removed regularly and disposed of by spreading evenly over stable, vegetated areas;

· Measures should be taken to minimize the ingress of site drainage into excavations.  If the excavation of trenches in wet periods is necessary, they should be dug and backfilled in short sections wherever practicable.  Water pumped out from trenches or foundation excavations should be discharged into storm drains via silt removal facilities;

· Open stockpiles of construction materials (for example, aggregates, sand and fill material) of more than 50m3 should be covered with tarpaulin or similar fabric during rainstorms.  Measures should be taken to prevent the washing away of construction materials, soil, silt or debris into any drainage system;

· Manholes should always be adequately covered and temporarily sealed so as to prevent silt, construction materials or debris being washed into the drainage system and storm runoff being directed into foul sewers;

· Precautions be taken at any time of year when rainstorms are likely, actions to be taken when a rainstorm is imminent or forecasted, and actions to be taken during or after rainstorms are summarized in Appendix A2 of ProPECC PN 1/94.  Particular attention should be paid to the control of silty surface runoff during storm events, especially for areas located near steep slopes;

· All vehicles and plant should be cleaned before leaving a construction site to ensure no earth, mud, debris and the like is deposited by them on roads.  An adequately designed and site wheel washing facilities should be provided at every construction site exit where practicable.  Wash-water should have sand and silt settled out and removed at least on a weekly basis to ensure the continued efficiency of the process.  The section of access road leading to, and exiting from, the wheel wash bay to the public road should be paved with sufficient backfall toward the wheel wash bay to prevent vehicle tracking of soil and silty water to public roads and drains;

· Oil interceptors should be provided in the drainage system downstream of any oil/ fuel pollution sources.  The oil interceptors should be emptied and cleaned regularly to prevent the release of oil and grease into the storm water drainage system after accidental spillage.  A bypass should be provided for the oil interceptors to prevent flushing during heavy rain;

· Construction solid waste, debris and rubbish on site should be collected, handled and disposed of properly to avoid water quality impacts;

· All fuel tanks and storage areas should be provided with locks and sited on sealed areas, within bunds of a capacity equal to 110% of the storage capacity of the largest tank to prevent spilled fuel oils from reaching water sensitive receivers nearby;

· Adopt best management practices;

· All earth works should be conducted sequentially to limit the amount of construction runoff generated from exposed areas during the wet season (April to September) as far as practicable.

Tunneling Works and Underground Works

· Cut-&-cover tunneling work should be conducted sequentially to limit the amount of construction runoff generated from exposed areas during the wet season (April to September) as far as practicable.

· Uncontaminated discharge should pass through sedimentation tanks prior to off-site discharge;

· The wastewater with a high concentration of SS should be treated (e.g. by sedimentation tanks with sufficient retention time) before discharge.  Oil interceptors would also be required to remove the oil, lubricants and grease from the wastewater;

· Direct discharge of the bentonite slurry (as a result of D-wall) is not allowed.  It should be reconditioned and reused wherever practicable.  Temporary storage locations (typically a properly closed warehouse) should be provided on site for any unused bentonite that needs to be transported away after all the related construction activities area completed.  The requirements in ProPECC PN 1/94 should be adhered to in the handling and disposal of bentonite slurries.

Groundwater from Potential Contaminated Area:

· No direct discharge of groundwater from contaminated areas should be adopted.

· A discharge license under the WPCO through the Regional Office of EPD for groundwater discharge should be applied. Prior to the excavation works within these potentially contaminated areas, the groundwater quality should be reviewed during the process of discharge license application. The compliance to the Technical Memorandum on Standards for Effluents Discharged into Drainage on Sewerage Systems, Inland and Coastal Waters (TM-DSS) and the existence of prohibited substance should be confirmed. If the review results indicated that the groundwater to be generated from the excavation works would be contaminated, the contaminated groundwater should be either properly treated in compliance with the requirements of the TM-DSS or properly recharged into the ground.

· If wastewater treatment is deployed, the wastewater treatment unit shall deploy suitable treatment process (e.g. oil interceptor / activated carbon) to reduce the pollution level to an acceptable standard and remove any prohibited substances (e.g. TPH) to undetectable range. All treated effluent from wastewater treatment plant shall meet the requirements as stated in TM-DSS and should be discharged into the foul sewers.

· If groundwater recharging wells are deployed, recharging wells should be installed as appropriate for recharging the contaminated groundwater back into the ground. The recharging wells should be selected at places where the groundwater quality will not be affected by the recharge operation as indicated in the Section 2.3 of TM-DSS. The baseline groundwater quality shall be determined prior to the selection of the recharge wells, and submit a working plan (including the laboratory analytical results showing the quality of groundwater at the proposed recharge location(s) as well as the pollutant levels of groundwater to be recharged) to EPD for agreement. Pollution levels of groundwater to be recharged shall not be higher than pollutant levels of ambient groundwater at the recharge well. Prior to recharge, any prohibited substances such as TPH products should be removed as necessary by installing the petrol interceptor.

Waste Management (Construction Waste)

S7.4.1

WM1

On-site sorting of C&D material

· Geological assessment should be carried out by competent persons on site during excavation to identify materials which are not suitable to use as aggregate in structural concrete (e.g. volcanic rock, Aplite dyke rock, etc.).  Volcanic rock and Aplite dyke rock should be separated at the source sites as far as practicable and stored at designated stockpile area preventing them from delivering to crushing facilities.  The crushing plant operator should also be reminded to set up measures to prevent unsuitable rock from ending up at concrete batching plants and be turned into concrete for structural use.  Details regarding control measures at source site and crushing facilities should be submitted by the Contractor for the Engineer to review and agree.  In addition, site records should also be kept for the types of rock materials excavated and the traceability of delivery will be ensured with the implementation of Trip Ticket System and enforced by site supervisory staff as stipulated under DEVB TC(W) No. 6/2010 for tracking of the correct delivery to the rock crushing facilities for processing into aggregates.  Alternative disposal option for the reuse of volcanic rock and Aplite Dyke rock, etc. should be explored.

· Adopt ‘selective demolition’ technique to demolish the existing structures and facilities with a view to recovering broken concrete effectively for recycling purpose, where possible;

· Implement a trip-ticket system for each works contract to ensure that the disposal of C&D materials are properly documented and verified; and

· Implement an enhanced Waste Management Plan similar to ETWBTC (Works) No. 19/2005 – “Environmental Management on Construction Sites” to encourage on-site sorting of C&D materials and to minimize their generation during the course of construction.

· Standard formwork or pre-fabrication should be used as far as practicable in order to minimize the arising of C&D materials.  The use of more durable formwork or plastic facing for the construction works should be considered.  Use of wooden hoardings should not be used, as in other projects.  Metal hoarding should be used to enhance the possibility of recycling.  The purchasing of construction materials will be carefully planned in order to avoid over ordering and wastage;

· The Contractor should recycle as much of the C&D materials as possible on-site. Public fill and C&D waste should be segregated and stored in different containers or skips to enhance reuse or recycling of materials and their proper disposal.  Where practicable, concrete and masonry can be crushed and used as fill.  Steel reinforcement bar can be used by scrap steel mills.  Different areas of the sites should be considered for such segregation and storage.

Land-based Sediment

· All construction plant and equipment shall be designed and maintained to minimize the risk of silt, sediments, contaminants or other pollutants being released into the water column or deposited in the locations other than designated location;

· All vessels shall be sized such that adequate draft is maintained between vessels and the sea bed at all states of the tide to ensure that undue turbidity is not generated by turbulence from vessel movement or propeller wash;

· Before moving the vessels which are used for transporting dredged material, excess material shall be cleaned from the decks and exposed fittings of vessels and the excess materials shall never be dumped into the sea except at the approved locations;

· Adequate freeboard shall be maintained on barges to ensure that decks are not washed by wave action.

· The Contractors shall monitor all vessels transporting material to ensure that no dumping outside the approved location takes place. The Contractor shall keep and produce logs and other records to demonstrate compliance and that journeys are consistent with designated locations and copies of such records shall be submitted to the engineers;

· The Contractors shall comply with the conditions in the dumping license.

· All bottom dumping vessels (Hopper barges) shall be fitted with tight fittings seals to their bottom openings to prevent leakage of material;

· The material shall be placed into the disposal pit by bottom dumping;

· Contaminated marine mud shall be transported by spit barge of not less than 750m3 capacity and capable of rapid opening and discharge at the disposal site;

· Discharge shall be undertaken rapidly, and the hoppers shall be closed immediately. Material adhering to the sides of the hopper shall not be washed out of the hopper and the hopper shall remain closed until the barge returns to the disposal site.

· For Type 3 special disposal treatment, sealing of contaminant with geosynthetic containment before dropping designated mud pit would be a possible arrangement. A geosynthetic containment method is a method whereby the sediments are sealed in geosynthetic containers and, the containers would be dropped into the designated contaminated mud pit where they would be covered by further mud disposal and later by the mud pit capping at the disposal site, thereby fulfilling the requirements for fully confined mud disposal.
