System” (the Project) serves to meet the future air traffic demands at Hong Kong International Airport (HKIA). On 7 November 2014, the Environmental Impact Assessment (EIA) Report (Register No.: AEIAR- 185/2014) for the Project was approved and an Environmental Permit (EP) (Permit No.: EP- 489/2014) was issued for the construction and operation of the Project. Airport Authority Hong Kong (AAHK) commissioned Mott MacDonald Hong Kong Limited (MMHK) to undertake the role of Environmental Team (ET) for carrying out the Environmental Monitoring & Audit (EM&A) works during the construction phase of the Project in accordance with the Updated EM&A Manual. This is the 11th Construction Phase Monthly EM&A Report for the Project which summarizes the monitoring results and audit findings of the EM&A programme during the reporting period from 1 November 2016 to 30 November 2016. Key Activities in the Reporting Period The key activities of the Project carried out in the reporting month were related to advanced works contract, which involved pilot hole drilling using Horizontal Directional Drilling (HDD) method at launching site, stockpiling of excavated materials from HDD operation at stockpiling area and casing installation on Sheung Sha Chau Island. CLP cable diversion enabling work contract was also carried out, which involved construction of drawpit, installation and backfilling for cable trough at the western part of the airport. The four in-progress deep cement mixing (DCM) contracts involved site investigation works, laying of geotextile and sand blanket. EM&A Activities Conducted in the Reporting Period The monthly EM&A programme was undertaken in accordance with the Updated EM&A Manual of the Project. During the reporting period, the ET conducted 33 sets of construction dust measurements, 21 sets of construction noise measurements, 13 events of water quality measurements, one round of terrestrial ecology monitoring on Sheung Sha Chau Island, two complete sets of small vessel line-transect surveys and five days of land-based theodolite tracking survey effort for Chinese White Dolphin (CWD) monitoring as well as landscape & visual and waste monitoring. Weekly site inspections of the construction works were carried out by the ET to audit the implementation of proper environmental pollution control and mitigation measures for the Project. Bi-weekly site inspections were also conducted by the Independent Environmental Checker (IEC). Observations have been recorded in the site inspection checklists and provided to the contractors together with the appropriate follow-up actions where necessary. On the implementation of Marine Mammal Watching Plan, trainings for the dolphin observers were provided by the ET prior to the deployment of silt curtain, with the training records kept by the ET. Visual inspection and integrity check for silt curtain were carried out by the contractor and their daily records were audited by ET and IEC during site inspection. Audits of acoustic decoupling for construction vessels and Skypier High Speed Ferries route diversion and speed control and construction vessel management were carried out by the ET. Mott MacDonald | Expansion of Hong Kong International Airport into a Three-Runway System 2 On the implementation of the Marine Travel Routes and Management Plan for High Speed Ferries of SkyPier (the SkyPier Plan), the daily movements of all SkyPier High Speed Ferries (HSFs) in November 2016 were in the range of 88 to 93 daily movements, which are within the maximum daily cap of 125 daily movements. A total of 837 HSF movements under the SkyPier Plan were recorded in the reporting period. All HSFs had travelled through the SCZ with average speeds under 15 knots (8.5 to 14.2 knots), which were in compliance with the SkyPier Plan, except that one HSF travelled with an average speed of 16.4 knots. Notice regarding the exceedance of average speed within SCZ was sent to the ferry operator and the case is under investigation by ET. One ferry movement not following the diverted route and four ferry movements with minor deviation from the diverted route are under investigation by ET. The investigation result will be presented in the next monthly EM&A report. In summary, the ET and IEC have audited the HSF movements against the SkyPier Plan and conducted follow up investigation or actions accordingly. On the implementation of the Marine Travel Routes and Management Plan for Construction and Associated Vessel (MTRMP-CAV), ET had conducted weekly audit of relevant information, including AIS data, vessel tracks and other relevant records to ensure the contractors complied with the requirements of the MTRMP-CAV. Training has been provided for the concerned skippers to facilitate them in familiarising with the requirements of the MTRMP-CAV. 3-month rolling programmes for construction vessel activities were also received from contractors. Results of Impact Monitoring All the monitoring works for construction dust, construction noise, water quality, construction waste, terrestrial ecology and CWD were conducted during the reporting period in accordance with the Updated EM&A Manual. No exceedance of the Action or Limit Levels in relation to the construction dust, construction noise, construction waste and CWD monitoring was recorded in the reporting month. The water quality monitoring results for dissolved oxygen (DO), total alkalinity and chromium obtained during the reporting period were in compliance with their corresponding Action and Limit Levels. For turbidity, suspended solids (SS) and nickel, some of the testing results had exceeded the relevant Action or Limit Levels during the reporting period. The summary of exceedances are presented in Section 4.5.2. Investigations were carried out immediately for each of the exceedance cases, and the investigation findings concluded that all the exceedances were not due to the Project. The monthly terrestrial ecology monitoring on Sheung Sha Chau Island observed that installation of casing was conducted on the Island and there was no encroachment upon the egretry area nor any significant disturbance to the egrets at Sheung Sha Chau by the works. Summary of Upcoming Key Issues Key activities anticipated in the next reporting period for the Project will include the following contract works: Advanced Works Contract: Contract P560 (R) Aviation Fuel Pipeline Diversion Works ● HDD pilot hole drilling; ● Stockpiling of excavated materials from HDD operation; ● Casing installation.
