2 Project information

2.1 Background

The existing Pillar Point Sewage Treatment Works (PPSTW) is located to the north of the Tuen Mun River Trade Terminal and is abutting the Lung Mun Road in the north. It is a preliminary treatment works with screening and grit removal processes and the treated effluent is discharged to the sea (North Western Water Control Zone) via a twin submarine outfall. The Review of the Tuen Mun and Tsing Yi Sewerage Master Plan (RTMTYSMP), commissioned in February 1999, recommended that the sewage treatment capacity be expanded and the plant be upgraded to chemically enhanced primary treatment (CEPT) with disinfection. This is to cater for the projected ultimate population and planned developments in the Tuen Mun area, and to improve the effluent quality reducing pollution loadings to the receiving waters.

The upgrading of the PPSTW comprises the following works:

· expanding the treatment capacity of the existing PPSTW to cope with the increased peak wet-weather sewage flow in Tuen Mun area;

· upgrading the sewage treatment level of the existing PPSTW to incorporate chemical treatment with disinfection at minimum removal rates of 70%, 55% and 99.9% of suspended solids (SS), biochemical oxygen demand (BOD) and E.coli, respectively;

· upgrading the existing septic waste reception facilities at PPSTW; and

· providing and upgrading ancillary facilities including the administration building, workshop, laboratory, odour control facilities, sludge handling and dewatering facilities, access roads and minor landscaping works within the STW for the operation and maintenance of the upgraded STW.

The potential environmental impacts of the Project have been studied in the “Upgrading of Pillar Point Sewage Treatment Works” (EIAO Register No: AEIAR-145/2008). The EIA was approved on 10 June 2008 under the Environmental Impact Assessment Ordinance (EIAO) and an Environmental Permit (EP-321/2008) for the works was granted on 17 November 2008. A variation of an Environmental Permit was granted on 23 April 2013 (EP-321/2008/A). Under the requirements of Condition 3.1 of EP-321/2008/A, an EM&A programme as set out in the EM&A Manual is required to be implemented.

The construction works commenced on 13 November 2010 and are scheduled for completion by 2014.

3.1.5 Monitoring Methodology

The setup locations of the HVSs were listed in Table 3.1. All HVSs were free-standing with no obstruction.

The following criteria were considered in the installation of the HVSs:

· appropriate support to secure the samplers against gusty wind were provided at AM1 and AM2;

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

· no furnace or incinerator flues was nearby;

· airflow around the sampler was unrestricted; and

· permission was obtained to set up the samplers and gain access to the monitoring stations.

Preparation of Filter Papers

· glass fibre filters were labelled and sufficient filters that were clean and without pinholes were selected;

· all 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 40%; and

· SGS Hong Kong Ltd, a HOKLAS accredited laboratory, implemented comprehensive quality assurance and quality control programmes.

Field Monitoring

· the power supply was checked to ensure that the HVSs were working properly;

· the filter holder and area surrounding the filter were cleaned;

· 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;

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

· 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;

· the shelter lid was closed and secured with an aluminium strip;

· the HVSs were warmed-up for about 5 minutes to establish run-temperature conditions;

· a new flowrate record sheet was inserted into the flow recorder;

· the flow rates of the HVSs were checked and adjusted to between 1.22 and 1.37 m³min^-1 which were within the range specified in the EM&A Manual (ie 0.6 to 1.7 m³min^-1);

· the programmable timer was set for a sampling period of 24 hours ± 1 hour, and the starting time, weather condition and the filter number were recorded;

· the initial elapsed time was recorded;

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

· the filter was placed in a clean plastic envelope and sealed;

· all monitoring information was recorded on a standard data sheet; and

· filters were sent to SGS Hong Kong Ltd for analysis.

Maintenance and Calibration

· the HVSs and their accessories were maintained in good working condition, eg. motor brushes were replaced routinely and electrical wiring was checked to ensure a continuous power supply; and

· 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 HVSs using CM-AIR-43 Calibration Kit. HVSs are calibrated on a bi-monthly basis. The calibration records for the HVSs are given in Annex F.

Environmental monitoring will be conducted at the same monitoring locations in the next reporting period. The monitoring programme has been reviewed and was considered adequate for the nature of works in progress.

9.1.3 Construction Programme for the Next Three Months

The most up-to-date construction programme for the Project is presented in Annex L.

10 Review of the EM&A DATA and EIA predictions

10.1 Air Quality

Since the EIA has only included a qualitative assessment of dust impact during the construction phase, a comparison was made between the monitoring results from the start of the Project and the Hong Kong Air Quality Objectives (HKAQO) (see Table 10.1).

Table 10.1 Comparison of the HKAQO and Air Quality Monitoring Results

Monitoring Station	Corresponding ASR in EIA	HKAQO, µg m^-3	Measured 24-hour TSP Monitoring Results, µg m^{-3 (a) (b)}
		24 hour ^(a)	Average	Range
AM1	A1	260	74	50 - 119
AM2	A7	260	78	51 - 109
Notes: (a) Only 24-hour TSP monitoring results were compared as there is no 1 hour TSP criterion in HKAQO. (b) The average and range of data were calculated from the period between the commencement of the construction works and this reporting month.

The monitoring results show that the average and range of the 24-hour TSP levels recorded since the commencement of the construction works have been well below the 24-hour TSP criterion in the HKAQO. Recommended mitigation measures in Section 3.7.1.1 of EIA have been implemented throughout the construction period and were considered effective.

10.2 Waste Management

The estimated amount of waste generated from the Project and the cumulative quantities of waste generated up to this reporting month are presented in Table 10.2. The amount of inert C&D material sent to public fills is higher than the estimated amount in the EIA. With reference to the C&D Material Assessment (Contractor’s General Submission (CSF) No.: DC200803/CSF/SAF/060026/A), the difference in quantities is mainly due to the differences in excavation depths and the excavation methods in the Contract Works and that assumed in the Reference Design. Recommended mitigation measures in Sections 7.5.1.1 to 7.5.1.9 of the EIA will continue to be implemented during the construction stage.

Table 10.2 Quantity of Amount of C&D Materials, General Wastes and Chemical Wastes Actually Generated and Estimated in the EIA and C&D Material Assessment

Type of Material	Estimated Amount of Public Fill and Construction Waste in the EIA (inert & non-inert)	Estimated Amount of Public Fill and Construction Waste in C&D Material Assessment (CSF No.: DC200803/CSF/SAF/060026/A) ^(c)	Accumulated Actual Amount of Public Fill and Construction Waste Recorded ^(a) ^(b) (inert & non-inert)
Amount of C&D Materials Arising	61,489.00 m³	77,600.00 m³	132177.45	m³
Amount of C&D Materials Reused on other site	-	-	3,163.89	m³

General Refuse	Small	-	2019.66	tonnes
Chemical Waste	Small	-	810.00	L
Notes: (a) The actual amount of C&D Materials has been recorded since the commencement of construction works. (b) The density of soil and rock (bulked) is 1.8 tonnes/m³. (c) The estimated amount of C&D material generated from the Contract Works was revised in the C&D Material Assessment and submitted to the SO on 9 September 2010 (CSF No.: DC200803/CSF/SAF/060026/A) because of the new plant & facility layout.

10.3 Conclusion of The Review

The EIA predictions and monitoring results since the commencement of the construction works have been reviewed. The EIA concluded that the Project would not cause adverse impacts to the environment, and monitoring results have also confirmed that so far. Mitigation measures recommended in the EP, EIA and EM&A Manual will continue to be implemented throughout the construction phase of the Project.
