B (指定工程項目的說明)


Hereunder is the description of the designated project mentioned in Part A of this environmental permit (hereinafter referred to as the “Permit”):




Title of Designated Project


Water Reclamation Facility for Kwun Tong Preliminary Treatment Works [This designated project is hereafter referred to as “the Project”]



[本指定工程項目下稱 工程項目”]


Nature of Designated Project

Reuse of treated sewage effluent from a water reclamation facility.



Location of Designated Project


Within the boundary of the existing Kwun Tong Preliminary Treatment Works



The location of the Project is shown in Figure 1 of this Permit.



Scale and Scope of Designated Project



Construction and operation of a water reclamation facility with a maximum design flow of about 50 m3/day, which comprises a membrane bioreactor plant (MBR plant), a reverse osmosis plant (RO plant), and related reclaimed water distribution system. The reclaimed water generated from the facility is for non-potable uses such as ground and facility washing, toilet flushing and landscape irrigation within the Kwun Tong Preliminary Treatment Works.





1.         General Conditions


1.1        The Permit Holder and any person working on the Project shall comply with all conditions set out in this Permit. Any non-compliance by any person may constitute a contravention of the Environmental Impact Assessment Ordinance (EIAO) (Cap. 499) and may become the subject of appropriate action being taken under the EIAO.


1.2        The Permit Holder shall ensure full compliance with all legislation from time to time in force including, without limitation to, the Noise Control Ordinance (Cap. 400), Air Pollution Control Ordinance (Cap. 311), Water Pollution Control Ordinance (Cap. 358), Waste Disposal Ordinance (Cap. 354) and Dangerous Goods Ordinance (Cap. 295). This Permit does not of itself constitute any ground of defence against any proceedings instituted under any legislation or imply any approval under any legislation.


1.3        The Permit Holder shall make copies of this Permit together with all documents referred to in this Permit or the documents referred to in Part A of the Permit readily available at all times for inspection by the Director or his authorised officers at all sites/offices covered by this Permit. Any reference to the Permit shall include all documents referred to in the Permit and also the relevant documents in the Register.


1.4        The Permit Holder shall give a copy of this Permit to the person(s) in charge of the site(s) and ensure that such person(s) fully understands all conditions and all requirements incorporated by the Permit. The site(s) refers to site(s) of construction and operation of the Project and shall mean the same hereafter.


1.5        The Permit Holder shall display conspicuously a copy of this Permit on the Project site(s) at all vehicular site entrances/exits or at a convenient location for public’s information at all times. The Permit Holder shall ensure that the most updated information about the Permit, including any amended Permit, is displayed at such locations.  If the Permit Holder surrenders a part or the whole of the Permit, the notice he sends to the Director shall also be displayed at the same locations as the original Permit.  The suspended, varied or cancelled Permit shall be removed from display at the Project site(s).


1.6        The Permit Holder shall construct and operate the Project in accordance with the project description in Part B of this Permit.


1.7        The Permit Holder shall ensure that the Project is constructed and operated in accordance with the information and recommendations described in the Project Profile (Register No: PP-389/2009); the application documents (Application No. AEP-367/009); and the information or mitigation measures described in this Permit. Where recommendations referred to in the documents of the Register are not expressly referred to in this Permit, such recommendations are nevertheless to be implemented unless expressly excluded or impliedly amended in this Permit.      


1.8        The Permit Holder shall notify the Director in writing the commencement dates of construction and operation of the Project at least two weeks prior to the commencement of construction and operation of the Project. The Permit Holder shall notify the Director in writing immediately if there is any change of the commencement dates of the construction and operation.


1.9        For the purpose of this Permit, “commencement of construction” does not include works related to site clearance and preparation, or other works as agreed by the Director.


2.         Special Conditions


2.1                The reclaimed water quality of this Project shall meet the standards set out in Table 1 of this Permit.


2.2                Any discharge from the proposed facility, any wastewater generated after non-potable uses of reclaimed water and any surplus or overflow reclaimed water under emergency situation shall be collected and diverted back to the sewage collection point of the Kwun Tong Preliminary Treatment Works.


2.3                To avoid mis-connection to potable water pipelines, the reclaimed water pipelines shall be clearly labeled with warning signs and notices; colour-coded; and /or of different sizes.


2.4                During operation stage, upon receipt of odour complaint and subsequent verification that the water reclamation facility generates odour impact, the Permit Holder shall install odour removal facility to mitigate the odour impact.





1.         This Permit consists of three parts, namely, Part A (Main Permit), Part B (Description of Designated Project) and Part C (Permit Conditions).  Any person relying on this permit should obtain independent legal advice on the legal implications under the EIAO, and the following notes are for general information only.


2.         If there is a breach of any condition of this Permit, the Director or his authorized officer may, with the consent of the Secretary for the Environment, order the cessation of associated work until the remedial action is taken in respect of the resultant environmental damage, and in that case the Permit Holder shall not carry out any associated works without the permission of the Director or his authorized officer.


3.         The Permit Holder may apply under Section 13 of the EIAO to the Director for a variation of the conditions of this Permit. The Permit Holder shall replace the original permit displayed on the Project site by the amended permit.


4.         A person who assumes the responsibility for the whole or a part of the Project may, before he assumes responsibility of the Project, apply under Section 12 of the EIAO to the Director for a further environmental permit.


5.         Under Section 14 of the EIAO, the Director may with the consent of the Secretary for the Environment, suspend, vary or cancel this Permit. The suspended, varied or cancelled Permit shall be removed from display at the Project site.


6.         If this Permit is cancelled or surrendered during construction or operation of the Project, another environmental permit must be obtained under the EIAO before the Project could be continued.  It is an offence under Section 26(1) of the EIAO to construct or operate a designated project listed in Part I of Schedule 2 of the EIAO without a valid environmental permit.


7.         Any person who constructs or operates the Project contrary to the conditions in the Permit, and is convicted of an offence under the EIAO, is liable:

(i)                  on a first conviction on indictment to a fine of $2 million and to   imprisonment for 6 months;
