1.              Introduction

1.1.            Background

1.1.1.            The EIA Study Brief (No: ESB-295/2016) for “Cycle Track between Tsuen Wan and Tuen Mun (Tuen Mun to So Kwun Wat)” (the Project) includes the requirement to prepare an Environmental Monitoring and Audit (EM&A) programme.

1.1.2.            The scope of the Project comprises the following:

i.      Construction of new cycle tracks of about 3.6 km long from Hin Fat Lane and Hoi Wing Road at Tuen Mun to Kwun Tsing Road at So Kwun Wat with associated footpaths

ii.     Construction of a marine cycle bridge with footpath of about 200 m long between Cafeteria Old Beach and Kadoorie Beach.

iii.    Provision of cycle parking areas near Hin Fat Lane, Cafeteria Old Beach and Kwun Tsing Road.

1.1.3.            The alignment of cycle track is shown in Figure 1.1.

1.2.            Project Implementation Programme

1.2.1.            The construction is scheduled to commence in the 1st quarter of 2023 and will be completed by the 3rd quarter of 2026 tentatively. 

1.3.            Purpose of EM&A Manual

1.3.1.            The purpose of this EM&A Manual (hereafter refer to as the “Manual”) is to guide the setup of an EM&A programme to ensure compliance with the EIA study recommendations, to assess the effectiveness of the recommended mitigation measures and to identify any further need for additional mitigation measures or remedial action.  This Manual outlines the monitoring and audit programme for both the construction and operational phase of the Project.  It aims to provide systematic procedures for monitoring, auditing and minimising environmental impacts associated with the construction and operational phases.

1.3.2.            This Manual specifies the EM&A requirements to ensure that the mitigation measures recommended in the EIA are effectively implemented and the whole EM&A programme properly managed.

1.4.            Contents in this EM&A Manual

1.4.1.            This EM&A Manual is prepared in accordance with Annex 21 of the Technical Memorandum on EIA Process (EIAO-TM) and the EIA Study Brief for the Project and follows the approach recommended in the EM&A Guidelines for Development Projects in Hong Kong.

1.4.2.            The EM&A Manual contains the following information:

§  project organization for the Project;

§  responsibilities of the Contractor, the Engineer or Engineer’s Representative (ER) and Environmental Team (ET) with respect to the environmental monitoring and audit requirements during the course of the Project;

§  requirements with respect to the construction programme schedule and the necessary environmental monitoring and audit programme to track the varying environmental impact;

§  details of the methodologies to be adopted, including all field laboratories and analytical procedures, and details on quality assurance and quality control programme;

§  definition of Action and Limit Levels;

§  establishment of Event and Action Plans;

§  requirements for reviewing pollution sources and working procedures required in the event of non-compliance with the environmental criteria and complaints;

§  requirements for presentation of environmental monitoring and audit data and appropriate reporting procedures.

1.4.3.            An implementation schedule of the environmental mitigation measures has been developed and presented in Section 14 in accordance with the requirements of Clause 3.5.3 of the EIA Study Brief.
