Executive Summary

1 Introduction

The title of this Report is Supplementary Environmental Impact Assessment (SEIA) For Proposed Increase Of Capacity Of Scheduled Wastes At Off Site Waste Recovery Facility On Lot 7842 And Waste Code Expansion At Off Site Waste Recovery Facility On Lot 7832-7835, Jalan Batu Tiga, Bukit Cherakah, Shah Alam, Selangor (hereinafter referred to as “the Project”).

The Project Proponent is currently operating two off site recovery facilities located on Lot 7842 and Lot 7832-7835 respectively. The existing Off Site Waste Recovery Facility on Lot 7842 is licensed to recover solder dross (SW 104); copper sludge (SW 204) and metal chip contaminated with oil (SW 422). At present, recovery activity conducted at Lot 7842 is very low due to limit of allowable approved licensed capacity. The existing Off Site Waste Recovery Facility on Lot 7832-7835 is licensed and is currently in operation to recover e- waste (SW 110).

The Project Proponent intends to increase the capacity of scheduled wastes namely solder dross (SW 104); copper sludge (SW 204) and metal chip contaminated with oil (SW 422) at its existing Off Site Waste Recovery Facility on Lot 7842. The Project Proponent also intends to do a waste code expansion namely spent catalyst, catalytic converter (PGM) (SW 202); resin epoxy, silver paste (SW 325); rag, paper or filters contaminated with scheduled waste (SW 410); sludge containing cyanide (SW 412); spent aqueous alkaline containing cyanide (SW 414) and photographic waste (SW 423) at its existing Off Site Waste Recovery Facility on Lot 7832-7835.

Even though the Project will be operated at existing Off Site Recovery Facilities, in compliance with the above requirement and as per the directive of the DOE Negeri Selangor in their letter [ref. no AS(PN)50/013/905/030 (48) dated 25 April 2014 an EIA report is required for submission and presentation to the DOE for approval prior to the Project implementation.

The objective of this Supplementary EIA is to ensure that all impacts, direct and indirect, especially environmental associated with the Project is fully examined and addressed.

4 Statement of Need

With the application to increase capacity of scheduled waste i.e. solder dross (SW 104); copper sludge (SW 204) and metal chip contaminated with oil (SW 422); this can enable the company to optimise operation at Lot 7842 and fully utilise all equipment which are now operating under capacity due to the present limit of allowable approved licensed capacity. The company is not able to meet the market demand as it is not able to cater the increase of supply amount offered by its existing clients.

Together with increase capacity at Lot 7842; additional waste code at Lot 7832-7835 i.e. spent catalyst, catalytic converter (PGM) (SW 202); resin epoxy, silver paste (SW 325); rag, paper or filters contaminated with scheduled waste (SW 410); sludge containing cyanide (SW 412); spent aqueous alkaline containing cyanide (SW 414) and photographic waste (SW 423) are deemed crucial; to complement services to existing and potential clients.

The objectives of the Project are also for business expansion, provide continuous services and to cater the company’s respective clients’ demand by managing and handling the scheduled wastes generated by them and also to offer service to potential clients. In this manner, there will be better control of waste generated from the waste generators which are of value and there will be an enhanced hierarchy in the management of these wastes.

6 Existing Environment

Topography

The topography of the Project site is mostly undulating terrain. The existing elevation is less than 50 m above mean sea level.

Geology

The geology of the area and its surrounding areas consist of marine and continental deposit comprising of clay, silt, sand peat and minor gravel.

Natural Drainage

The Project site is located within Sungai Klang river basin whereby discharge from the Project site as well as discharges from neighbouring industries enter nearby seasonal monsoon drainage system before entering Sungai Lumut prior discharging into Sungai Damansara and eventually into Sungai Klang.

Meteorology and Climate

The Project site experiences an equatorial type of climate characterised by warm and humid weather all year round. It is under the influence of the Asian Monsoon system. Annual prevailing winds was from the northwest.

The average monthly 24 hours mean temperature varies between 26.4 °C and 27.7°C. The highest humidity was recorded during the month of November (84.5%), whilst the lowest relative humidity was recorded in February (79.9%). The average annual rainfall amount for the period of 1966 to 2010 was 2529.3 mm. The highest average rain days was recorded in November (22 days).

Air Quality

Ambient air monitoring exercise was carried out at two selected sampling locations. It is noted that all parameters at all stations are well below the Malaysian Ambient Air Quality Standard (MAAQS) limits.

Water Quality

Water sampling was conducted at one sampling location. Generally, the parameters were below the National Water Quality Standards for Malaysia (NWQSM) except for BOD, COD and Ammoniacal Nitrogen. The WQI obtained indicates that the water quality at W1 falls under Class III (slightly polluted) with a value of 72.61.

Noise Level

Noise measurement was carried out to determine day time and night time noise levels. Results at the respective points complied with the Planning Guidelines for Environmental Noise Limits and Control (Schedule 1 under Urban Residential (High Density Areas, Designated Mixed Development Areas (Residential-Commercial)) of Department of Environment.

8 Residual Impacts

The assessments on potential environmental impacts due to the Project have indicated that some residual impacts will exist even after the implementation of planned and recommended mitigation measures. These residual impacts are air emission, waste water loading, residual waste as well as hazard and risk.

9 Conclusion

The potential impacts from the Project activities to the surrounding natural and social environment have been documented in Chapter 4. Various mitigation measures have been prescribed for potential impacts that are deemed to be of concern.

In order to ensure that the measures implemented are effective at all times and residue impacts remain insignificant, the existing Environmental Management Plan with associated environmental monitoring and auditing as well as Emergency Response Plan are recommended to be updated in order to ensure the effectiveness of both plans.

This Supplementary EIA study has demonstrated that, with proper incorporation of the recommended mitigating measures, the Project can be implemented with acceptable environmental risk and impacts.
