2                                          Project information

2.1                                      Background

The Organic Waste Treatment Facilities (OWTF) Phase I development (hereinafter referred to as “the Project”) is to design, construct and operate a biological treatment facility with a capacity of about 200 tonnes per day and convert source-separated organic waste from commercial and industrial sectors (mostly food waste) into compost and biogas through proven biological treatment technologies. 

The environmental acceptability of the construction and operation of the Project had been confirmed by findings of the associated Environmental Impact Assessment (EIA) Study completed in 2009.  The Director of Environmental Protection approved this EIA Report under the Environmental Impact Assessment Ordinance (EIAO) (Cap. 499) in February 2010 (Register No.: AEIAR-149/2010) (hereafter referred to as the approved EIA Report).  Subsequent Report on Re-assessment on Environmental Implications and Report on Re-assessment on Hazard to Life Implications were completed in 2013, respectively.

An Environmental Permit (EP) (No. EP-395/2010) was issued by the Environmental Protection Department (EPD) to the EPD, the Permit Holder, on 21 June 2010 and varied on 18 March 2013 (No. EP-395/2010/A) and 21 May 2013 (No. EP-395/2010/B), respectively.  The Design Build and Operate Contract for the OWTF (Contract No. EP/SP/61/10 Organic Waste Treatment Facilities Phase I (the Contract)) was awarded to SITA Waste Services Limited, ATAL Engineering Limited and Ros-Roca, Sociedad Anonima jointly trading as the OSCAR Bioenergy Joint Venture (OSCAR or the Contractor).  A Further EP (No. FEP-01/395/2010/B) was issued by the EPD to the OSCAR on 16 February 2015.  Variation to both EPs No. EP-395/2010/B and No. FEP-01/395/2010/B were made in December 2015.  The latest EPs, No. EP-395/2010/C and No. FEP-01/395/2010/C, were issued by the EPD on 21 December 2015.

Under the requirements of Condition 5 of the EP (No. FEP-01/395/2010/C), an Environmental Monitoring and Audit (EM&A) programme as set out in the Agreement No. CE7/2008 (EP) EM&A Manual (hereinafter referred to as EM&A Manual) is required to be implemented.  ERM-Hong Kong, Ltd (ERM) has been appointed by OSCAR as the Environmental Team (ET) to undertake the EM&A programme for the Contract.

The construction works commenced on 21 May 2015 and are scheduled for completion by April 2017.

6                                          Environmental Inspections

6.1                                      Weekly Site Audits

Joint site inspections were conducted by representatives of the Contractor, the ER, IC and the ET on 6, 15, 20 and 27 June 2016.  The IEC was also present at the joint inspection on 15 June 2016.  Follow-up actions resulting from the last site inspections were taken as reported by the Contractor and their results were observed in the site inspections conducted in the reporting period.

Key observations during the reporting period are summarised as follows:

6 June 2016

·      Dust screen at the site boundary near the AD Tank area were found to be incompletely covering the site.  The contractor was recommended to ensure the dust screen is enclosing the site properly.

·      General refuses were observed in the Building 2 area.  The contractor was recommended to clear the general refuses regularly.

15 June 2016

·      Chemical containers were observed to be without secondary containment near the AD tank and inside Building 2 area.  The contractor should provide drip trays to retain the chemicals in case of any leakage in accordance with the COP.

20 June 2016

·      The vehicle route near AD Tank area was observed to be in dry and dusty condition.  The contractor was recommended to spray water to prevent adverse impact to air quality.

27 June 2016

·      Inappropriate chemical containers were observed to be without a secondary containment inside Building 2 area.  The contractor should provide drip trays to retain the chemicals in case of any leakage in accordance with the COP.

6.2                                      Landscape and Visual Audit

In accordance with the EM&A Manual, bi-weekly landscape and visual inspection is required to ensure that the design, implementation and maintenance of landscape and visual mitigation measures recommended in the EIA Report are fully achieved.  Onsite inspections of the landscape and visual mitigation measures were performed on 15 and 27 June 2016.

Follow-up actions resulting from the last site inspections were taken as reported by the Contractor and their results were observed in the site inspections conducted in the reporting period.

It was confirmed that the necessary landscape and visual mitigation measures as summarised in Annex E were generally implemented by the Contractor.  No specific observation was found during site inspection on 15 and 27 June 2016.
