10.0 MITIGATING MEASURES DURING EARTHWORKS

There will be no excessive earth during the earthworks. Preliminary estimate shows that approximately 45,000 m3 of soil will have to be imported to the site to higher the ground level. Source of imported earth to be identified at later stage. Amount of cut and fill will be minimum for foundation works only. A temperary earth stockpile will be provided to stockpile the earth during the foundation stage. Location of earth stockpile is shown in Appendix F.

An Erosion and Sediment Control Plan (ESCP) is established for the proposed development to mitigate and minimize environmental impacts arising from earthwork activities. Among the best management practices (BMPs) adopted are: . Stabilised access will be installed at the entrance to the construction area. . A sediment basin will be built to receive silty runoff within the project site. . Temporary drainage system will be built along the project site boundaries to channel runoff into the sediment basin before discharging off-site. . Temporary earth stockpile with proper bunding.

An erosion and sediment control plan (ESCP) for the project site is shown in Appendix F. It will be implemented before commencement of earthwork. Further elaboration on the BMPs are given below.

Temporary Metal Hoarding Metal hoarding shall be erected along the internal boundary facing the public roads. This is to prevent unauthorised persons from encroaching into the construction site.

Stabilized Access with Wash Trough Entrance to the project site shall be stabilised with a layer of gravel at least 10 m into the site from the main road. The wheels of machineries shall be cleaned by spraying with water to remove soil and earth materials before being transported out of the project site. A wash trough shall be constructed at the entrance to remove excessive sediment from out-bound vehicles.

Temporary Drainage System Temporary earth drains will be constructed within the project area to channel overland flow from the disturbed area into the sediment basin, before discharging into the roadside drain. The drainage system should be regularly inspected and maintained, especially after each heavy downpour.

Sediment Basin A sediment basin will be allocated near to the entrance of the project site (Appendix F), receiving runoff from the temporary earth drains. The sediment basin must be maintained regularly, depending on the rain conditions to achieve maximum efficiency. Inspection of the sediment basin and temporary earth drain and other mitigation measures should be carried out after every storm event. In this respect, a rain gauge will be installed on-site and inspections should be carried out within 24 hours for storm event that exceeds 12.5mm. A copy of inspection report should be forwarded to DOE within 24 hours upon

EIA for Production of Extender Oils at PLO 13, Tg Langsat Industrial Complex Supplementary Report inspection. Corrective actions / maintenance of BMPs, if any, should be reported to DOE as well within 7 days after the storm event. Removal of accumulated sediment in the sediment basin will be carried out manually.

Water discharged from the sediment basin shall not exceed TSS level of 50 mg/l. Monthly sampling of water quality must be carried out to enable pollution prevention steps to be taken. A maintenance log should be kept for the sediment basin, detailing the inspection and desilting work.

Stockpile Area Temporary earth stockpile will be provided onsite as shown in Appendix F. Any stockpile for topsoil or earth material shall be located away from any waterway, suitably compacted and sprayed with water to prevent generation of wind-blown dust. A low bund shall be built surrounding the stockpile to contain siltation.

11.0 SOLID WASTE MANAGEMENT

11.1 Solid Waste Management during the Construction Phase

During the construction phase, improper management of domestic waste could lead to proliferation of disease vectors as well as degradation of aesthetic value. The likely wastes generated from the construction activities are limited to biomass, garbage from the site office and construction wastes. The estimated volume of wastes are:  Biomass: 1 ton/ha x 2.833 ha = 2.833 ton  Construction waste: 50 ton/ha x 2.833 ha x 50% structural built up = 70.8 ton  Site office refuse: 0.5 ton/mth x 23 months = 11.5 ton

For construction waste and site office refuse, they will be temporarily stored on-site and will be regularly disposed by licensed contractor to the solid waste disposal site similar to biomass as shown in Section 5.0. The location of storage on-site is shown in Appendix F.

11.2 Solid Waste Management during the Operational Phase

During the operational phase, solid waste generated is limited to general domestic waste such as office refuse, food waste etc. Waste volume is estimated to be 5.0 ton/mth. They will be temporarily stored on- site at the refuse chamber (refer to B6 – refuse chamber in Appendix B – site layout plan) and will be regularly disposed by licensed contractor to the solid waste disposal site within Tanjung Langsat Industrial Complex as shown in Section 5.0.

EIA for Production of Extender Oils at PLO 13, Tg Langsat Industrial Complex Supplementary Report

12.0 SCHEDULED WASTE MANAGEMENT

12.1 Scheduled Waste Management during the Construction Phase

During the construction phase, the generation of spent oil and grease material will come from maintenance of machinery. Maintenance of construction heavy vehicles will be carried out off-site. This spent oil is categorized as scheduled waste under the Environmental Quality (Scheduled Wastes) Regulations, 2005. The amount generated would be minimal due to the limited number of machinery required for such a small-scale construction works. In view that the project site is not located in a remote area, there is no requirement for a diesel / petroleum storage tank to be placed on site as a filling station. This negates any potential diesel spillage during construction. Based on this, it can be inferred that the contamination of oil and grease material from the project activities during the construction stage is confined to generation of spent oil material. The spent oil material is expected to take up only 10 drums (within the entire construction period). The oily waste should be collected and handled as per Environmental Quality (Scheduled Wastes) Regulations, 2005. Disposal and collection of Scheduled Wastes shall be handled by DOE’s licensed contractor. Potential licensed contractor for off-site spent oil recovery facilities are:  5E Resources Sdn Bhd, Kawasan Perindustrian Pasir Gudang  Chemalaya Sdn Bhd, Tanjung Langsat Industrial Complex  Modern Energy Sdn Bhd, Kawasan Perindustrian Pasir Gudang  OLST Petro-Chemical Snd Bhd, Kawasan Perindustrian Pasir Gudang

Besides, proper temporary storage of scheduled waste on-site should be built with following criteria:  Signage of scheduled waste storage.  Pavement, roofed and surrounded by low bund wall.  Labelling of scheduled wastes.

The location of scheduled waste storage on-site during the construction phase is shown in Appendix F.

12.2 Scheduled Waste Management during the Operational Phase

The production process generates several scheduled wastes as shown in Table 6.

13.0 DRAINAGE AND WASTEWATER TREATMENT SYSTEM DURING THE OPERATIONAL PHASE

13.1 Off-Site Drainage System

Surface runoff from the project site will be discharging via final outlet of the project site to road side drain of the Jalan Tengar before entering Straits of Johor. Drainage pattern in adjacent to the project site is shown in Figure 13.

13.2 On-Site Drainage System

Within the project site, drainage system of the entire plant generally will be separated into two, namely:  Process water drainage system for plant facilities such as tank farm, pump stations, fire water pump, truck loading/unloading, boiler package and ISBL processing units.  Stormwater drainage system for general areas other than the above such as office building and internal road.

Process water maybe contaminated by oil material and therefore will be treated prior to discharging off- site while the stormwater will be directly discharging off-site without treatment. A conceptual drainage system within the project site and flow diagram of the treatment system is shown in Appendix G. As shown, there are numerous oil water separators (OWS) located at the plant facilities (tank farm, pump

EIA for Production of Extender Oils at PLO 13, Tg Langsat Industrial Complex Supplementary Report stations, fire water pump, truck loading/unloading, boiler package and ISBL processing units) respectively. Surface runoff from such facilities collected at these facilities will be treated at the oil water separator (OWS). Subsequently, runoff will go through tilted plate interceptor and the treated water will be discharging into retention pond onsite while the collected oil material will be pumped to the slop oil tank. In addition to the OWS, slop sump is provided at the tank farm to collect slop oil. Slop oil (also known as waste oil) is obtained in the course of cleaning oil tanks or by way of leaks from oil processing installations. Slop oil collected will be directly pumped to slop oil tank. The collected oil material at the slop oil tank will be disposed off-site as scheduled waste – oil sludge (SW311). Management and handling of this oily sludge is described in Section 12.2.

Besides, a standby Industrial Effluent Treatment System (IETS) will also be provided on-site to handle instantaneous contaminated water in huge volume such as tank cleaning water during tank maintenance. During the tank cleaning, the tank cleaning water collected at slop sump will be channeled to IETS, bypassing the tilted plate interceptor and slop oil tank. Maximum volume of tank cleaning water at once is estimated at 10m3/hr. Design of the standby IETS shall notify DOE at later stage as per Environmental Quality (Industrial Effluent) Regulations 2009.

14.0 GAS TREATMENT SYSTEM

To handle the residual non-condensed vapors of DMSO and products of its degradation in the emissions of vacuum pumps and tanks’ "breathing" (for tanks filled with DMSO or DMSO-containing substances) a two-stage absorption/adsorption process is put in place: - at the first stage the DMSO vapors are absorbed by the water supplied for absorber sprinkling; - the second stage adsorption is designed to capture the water-unsoluble sulphur-containing compounds and the remaining DMSO vapors.

Piping & Instrumentation Diagram (P&ID) of the gas treatment system is attached in Appendix H.

By means of a fan, the non-condensed gases are extracted from the above-mentioned equipment through the absorber А-4.100. The water used in the absorber as the absorptive agent is supplied from tank Е-4.100 by the pump Н-4.1001. The sprinkling water circulated by the following route:

Е-4.100---Н-4.1001---А-4.100---Е-4.100.

The gas emissions from absorber А-4.100 are heated by 10-150С by means of the electric heater. The set temperature range is sustained by respective de-/activation of the heating devices. The heated gas emissions then follow into adsorber АD-4.100 to be treated with activated carbon, and once treated, clean emission is blown into the atmosphere by means of the fan. Sampling for DMSO and sulphur compounds content are scheduled on the discharge line of B-4.100 and in case of detected contamination the bypass АD-4.100 is used while active carbon is being refilled afresh.

15.0 SOCIO-ECONOMIC IMPACTS DUE TO FOREIGN WORKERS

During the construction phase, number of workers is limited to 100 maximum. Foreign workers are expected to be 50 maximum. The influx of foreign workers would bring with it a different kind of impact, both positive and negative. The plus point would be the fulfilment of the labour demand for the construction works and the minus point would be the potential social and cultural complications that may arise from it. Nevertheless, the impact is short term in nature during the construction period of 23 months from Mar 2016 to Jan 2018. - Accommodating foreign workers in one place to minimize conflicts, in any with the locals. - Workers’ health screening prior to work commencement to ensure they are free from any possible infectious disease.

During the plant operations, the workforce will comprise manager, engineers, skilled workers and semi- skilled workers. The worker will be locals in majority and engagement of foreign workers will be minimum. Significant impact due to influx of foreign workers is not foreseen at this stage.

16.0 HEALTH DATA

Table 7 gives the number of cases and incidence rates of selected communicable diseases in Johor, in comparison with the national incidence in 2013. The most common communicable diseases in Johor are dengue fever and food poisoning that recorded 4,750 cases and 1,447 cases in year 2013. Of the selected diseases, cholera and typhus has no cases in Johor in year 2013. Overall, Johor state has lower incidence rate when compared to the nation. Dengue fever, dengue haemorrhagic fever and food poisoning have the incidence rates that closer to the national rates.
