E.6

Statement of Need

Generally the proposed project is necessary in view of the following:

The proposed KPTC-MIRPD will be developed on Investor Lot 2 of Pengerang Integrated Petrochemical

Complex (PIPC). Development of KPTC-MIRPD is important to realise PIPC development aspiration to

transform Pengerang area into an oil and gas hub in southern Johor. From the local perspective, the

development of KPTC-MIRPD within PIPC is important to provide synergy with RAPID and DIALOG

development within the PIPC development zone. It enables product compensation and supplement

among the plants within the PIPC and allow greater optimisation of investment return for the

infrastructure development necessary to facilitate PIPC development.

Besides, it is also important to simulate the development of the entire Pengerang area as proposed in

the Draft RKK, Pengerang where a drastic rezoning for the area has been proposed to develop the area

into petrochemical industrial zone, commercial and residential as well as eco-city and resort

development zone. To realise the development aspiration as proposed in the Draft RKK, the development

of KPTC-MIRPD and thus PIPC is important to bring economic spinoff effects within the region and

subsequent simulate the chain effects and promote development for the entire area.

From the national perspective, the development of the project i.e. oil and gas industries has been

identified as one of the Economic Transformation Program (ETP) under the National Key Economic Area

(NKEA) and it has been translated into the ISKANDAR oil and gas development plan. The development of

the proposed KPTC-MIRPD is hence important to meets the ISKANDAR and national economicdevelopment aspiration. The proposed KPTC-MIRPD is estimated to bring in a foreign investment of

approximately RM40 billion and it is expected to contribute approximately RM40,000 million to the

national annual revenues upon full operation of the plant. An estimate of around 40,000 employment is

expected during the construction stage of the project and approximately 3,000 employment opportunity

during the operation of the project.The proposed project is one of the significant developments to fulfil

the state oil and gas development aspirations as drawn in the ISKANDAR oil and gas labs vision and

PIPC development plan.

Besides, the production from the proposed KPTC-MIRPD is also important to meet national future energy

demand. Based on PETRONASs demand-supply balance as presented in RAPID DEIA, upon

commencement of RAPID project in year 2016, shortage of supply are still expected for some of thepetroleum products and these shortages could be supplied from the proposed KPTC-MIRPD. The


8/40

production from the proposed project will also feed into the global market for oil product particularly to

meet the demand from the developing countries especially China and India.

E.7

Project Description and Development

The proposed development principally is to develop an integrated petrochemical complex comprises of

an oil refinery plant with a naphtha cracker and aromatic plant and 6 major petrochemical production

units. The complex conceptually involved production of LPG, Naphta, Gasoline, Diesel and Kerosene oil

products from Arabian Crude Oil and Condensate in the refinery complex. Naphtha produced from the

refinery plant will be further refined in Napththa Cracker and Aromatic Complex to produce ethylene and

paraxylene which both of these products will be used as the feedstock in the Petrochemical complex for

production of various high value-added special petrochemical derivatives.

The main component of the proposed KPTC-MIRPD could be broadly group into two production floor as

follows:

a) Refinery complex which consist of a crude distillation unit, naphtha cracker and aromatic

unit

b) Integrated Chemical Complex which consists of 6 major petrochemical production units for

derivative C2, C3, C4, C5, BTX and C9+.

Besides the above main development component, the proposed project also comprises the development

of the associated support facility to facilitate the production floor. Amongst this includes steam and

power generation plant, condensate system, internal water system, air separation system, fuel and gas

system, flare system, intermediate storage system, wastewater treatment system, solid waste handling

system as well as associated administration and support building development.

The project development layout is presented inFigure E-3.The process areas are arranged along the

northern and southern site of the proposed main roads and separated from each other by internal roads

provided for maintenance access to machines and equipment. The utilities units (e.g. Steam, Air, Water,

etc) are located within the process areas of Refinery, Aromatics, Olefins, and Petrochemical Complex.

The storage facilities for all liquid products (e.g. crude, oil products and petrochemical products) are

located at the southwest of the site while the solid products will be stored at northwest of the site.

Approximately 88.8 acres of hilly area at the northern and eastern boundary which recorded an elevation

of 111 and 55m respectively have been reserved as green field without development. A big portion of

the land towards the north-western of the site has been reserved for future expansion.

The development of the project is envisaged to be started in 2014 with target production

commencement in early 2018.

E.7.1 Refinery Complex

The refinery complex is designed to process and refine 150,000 Barrel per stream day (BPSD) of light

and heavy Arabian Crude Oil (of which 50% Arabian Light and 50% Arabian Heavy) and 40,000 BPSD ofcondensate oil. The main process component in the refinery complex includes the oil refinery, the

naphtha cracker and the aromatics plant.

In the refinery process, crude oil will be fed into distillation unit to obtain various oil fractions such as

gasoline, kerosene, light fuel, heavy fuels, etc under difference boiling points. The major products from

the proposed refinery process are summarizes as below:

Product Production Capacity Unit

LPG (liquefied petroleum gas) 357,632 MT/YR

92 Gasoline 2,076,000 KL/YR

95 Gasoline 2,514,263 KL/YR

98 Gasoline - KL/YR

Jet Fuel 1,149,539 KL/YR

Diesel Oil 2,504,647 KL/YR

N-paraffins 97,986 MT/YR

Fuel Oil 377,565 KL/YR

p-Xylene 917,718 KL/YR

NCB 259,751 KL/YR

Naphtha and some of the heavy oil products produced from the crude distillation unit will be further

refined in the Naphtha cracker which involve high temperature cracker and the cracked gas will

subsequently undergo quench/chilling, compressing, low temperature distillation process to produce

lighter and more useful products such as ethlylne, propylene, butadiene, H2, etc.

While in the aromatic complex, aromatic process converts heavy naphtha from refinery into aromatics

product such as benzene, toluene, and paraxylene by means of reformer, separation and transalkylation

process.

Ethylene, propylene, butadiene, raffinate, C5 olefins, benzene and para-xylene produced from the

nathptha cracker and aromatic plant form the raw material / feedstock for the downstream

petrochemical process for production of specialized and differentiated petrochemical derivatives.

E.8 Project Option

E.8.1

Site Option

Generally two potential sites have been considered for the development of the proposed project. Both of

the potential sites were determined by the Johor Petroleum Development Corporation (JPDC) i.e. at

Investor Lot 2 and Investor Lot 3 within the PIPC development zone. Site A (Investor Lot 2) has a total

land cover of approximately 1,476 ha while Site B (Investor Lot 3) is significantly smaller with only

approximately 809 ha.

Based on the evaluation of both of the alternatives sites, Site A i.e. investor Lot 2 has been selected due

to the following reason:

Bigger land acreage is available and this provides more flexibility in project development layout

alignment

No significant settlement is located within the site. Only 11 houses are located within the project

site and this is expected to significantly minimise the potential social impacts in results to

resettlement issues

No religious or cultural heritage significant site is located within the project boundary and this is

expected to minimise social conflicts

Generally the site is less populated and with lesser commercial activities in comparison to

investor Lot 3

While in terms of topography, environmentally sensitive landuse, as well as accessibility and

infrastructure, site B (Investor Lot 3) was found in preference however the constraints predicted in site A(Investor Lot 2) could be easily mitigated through design consideration.

E.8.2 No Project Option

The evaluation of With Project and No Project Option has been assessed from various perspectives

including the oil product supply and demand needs, regional and local development aspiration, existing

social and environmental conditions, landuse and resources, as well as the economic benefit from the

project.

In overall, the findings of the evaluation suggested that the proposed project to be implemented with the

following justifications:-

There is a need to increase the capacity of oil refinery and petrochemical production within the

region. By 2020, shortage of oil product is also anticipated within the country

The implementation of this project is necessary to facilitate the PIPC, ISKANDAR and the RKK,

Pengerang development aspirations

The foreign investment to be brought in and the estimated economic benefit from the project is

significant to the ETP and long term national revenue

From the social aspect, the development of the project will only involves limited number of

family relocation and no religious or cultural heritage significant site is located within the project

area

In terms of environment, no environmentally sensitive area is located within the site. Vast area

within the site has been disturbed and only small patches of regeneration forest with common


18/40


________________________________________________________________________________________________________


species are located within the site. Hence the development of the project is not anticipated to

cause significant loss to the environmental diversity / conservation values for the area

Some environmental emission and discharge will be anticipated from the implementation of the

project however this could be mitigated with the control technology and on-going management

and monitoring program. The development of the proposed project within the PIPC also ensures

that all the necessary environmental treatment and final disposal/ discharge requirements is

centrally coordinated and monitored by PIPC. This includes the coordinated risk and emergency

management within the region. Such centralised and coordinated approach will reduce the risk of

undesired discharge/emission to the surrounding environment.

Environmental

Component

Description

Physical Environment

Topography and

Landform

Project site is undulating with elevations ranged from 2m to 111m where

higher elevations are mainly distributed at the northern part of the project

site

Slope within the site is mostly below 20o, recorded 99.24% of the site,

followed by 20o-24o(0.56%) and only 0.2% is above 24o

Geology & Soil Rock exposure is only discovered at the northern boundary (near Bukit

Hutan/Forest Hill) of the project site. The rock is mainly volcanic comprising

of andesite and rhyolite

Other hilly terrain within the site contains mainly earth material (lateritic

soil) being the weathering product of volcanic rocks in the area

Pengerang area is recorded with bauxite mining however there is no active

bauxite mines within the project site

4 soil samples collected within the boundary of the project site indicated that

the lateritic soil at the project site has lower potential for bauxite compared

to the typical bauxite value in Pengerang area

While at the low lying area to the east, west and south and in between the

small hill of the project site are generally underlain by a thick layer of

swampy deposit that comprises of grey and yellow swamp clay and marine

sands

Seismic Activities There is no fault and fold within the site and the risk of fault movement due

to earthquake is very small and the site is seismically safe

Based on the seismic information from the Meteorological Department of

Malaysia, the Project site is not located within the critical unstable seismic

zone and can be considered as low adverse impact to the structures of the

proposed project

Hydrogeology The measured groundwater levels in the study area are generally ranged


19/40


________________________________________________________________________________________________________


between 0.1 and 2.5 meter below the ground surface. It represents the

groundwater levels of approximately between 5 and 36 meter above mean

sea level (a.m.s.l.).

At hilly area particularly the middle and northeast of the project site, the

groundwater levels are recorded between 2-3 meter below ground level and

it decrease to less than 1 meter outside the southern boundary of the

project, towards the sea.

Based on simulated results, ground water heads at the project site are

generally between 15-25 meter. At low area and the flat terrain area,

groundwater level are generally shallow that is less than 5m below the

ground however at hilly area, groundwater heads are varied in order of more

than 10m.

Hydrology The project is drained by four river system namely Sg. Lepau, tributary of Sg.Sebina, Sg Kapal and Sg. Rengit. Sg Lepau and Sg Sebina form the sub-

catchment of Sg. Santi. Three of these main river catchments recorded

comparable shares of the project site.

Climate and

Meteorology

Meteorological data for the study area is obtained from Changi Airport in

Singapore

The mean annual rainfall is 2268.8mm for the 10-year data. The recorded

highest daily mean rainfall is 321.7mm while the recorded lowest daily mean

rainfall is 84.5mm

Annually, a total of 1.07% of calm period was recorded. Prevailing wind is

from northeast and southeast directions with 11.7% and 11.6% of the time

respectively. The highest wind speed is recorded at 7.7 m/s

Landuse The existing landuse within the project site is dominated by agriculture land

(80%) comprises mainly mix vegetation, short term crop farming, orchard,

some poultry & swiflet farming and some oil palm plantation. The remaining

20% are industrial landuse and natural greenfield both has a comparable

shares. Industrial landuse consist of ex-bauxite mines followed by active

quarry and several concrete tile factories while the greenfield comprises of

secondary forest and natural water bodies including some swampy area

While landuse within 5km radius from the project boundary are generally

agriculture occupied mainly by oil palm plantation at the northern and short

term crops/ mix vegetation towards the western. The eastern boundary of

the project site is mainly bauxite mines and the Teluk Ramunia Yard is

located southeast. Rural village settlements are recorded mainly along Jalan

52 and 91 along the coastline towards the southern of the project site. This

includes the most dominant business and settlement township for the area

i.e. Kg Sg Renggit

Baseline groundwater quality was collected from the 6 borehole drilled within

the project site and 9 samples were collected from the public well

surrounding the project site.

Groundwater quality within the project site shows acidic characteristic

probably due to organic peat layer within the area. While the concentration

of sulphate, organic and chloride given as percentage are considered very

low and below the environmental standard. Other parameters monitored

were below the levels of Malaysia Site Screening Levels (SSLs) of

contaminated land.

While for the groundwater samples taken surrounding the project site, the

test result shows that groundwater can be considered as acidic with

concentration of a few parameters such as nitrate (NO3) and Total Coliform

above the Environmental Standards. Hygienic groundwater quality was

relatively poor, with high counts of coliform bacteria. No pollution of heavy

metals was detected and visual inspection shows that there is no petroleum

compounds detected in the groundwater

Ambient Air Baseline ambient air monitoring was carried out from 5 thto 24thNovember

2012 at 14 locations within and surrounding the project boundary

Based on the results obtained, levels of TSP, PM10, NO2, SO2, CO are well

under the respective limits of Malaysian Ambient Air Quality Guidelines for all

sampling stations. Parameters of Hg, H2S and Cl2 were not detected at all

stations. Besides, low concentrations were recorded for other parameters

(NH3N, HCl and VOC) with values not more than 0.4 mg/m3, 0.3 mg/m3and

0.01 mg/m3 respectively

Environmental Noise 24 hours ambient noise baseline monitoring was conducted from 5thto 24th

November 2012 at 14 locations within and surrounding the project

boundary. The existing noise level of the study area was recorded from 49

dBA to 65 dBA Leq during daytime and 41dBA to 64dBA during night time


21/40


________________________________________________________________________________________________________


During daytime, existing noise at Kg Bkt Buloh and the western boundary of

the project site has exceeded 60 dBA Leq while during night time, noise at

most monitoring points has exceeded 50 dBA except at Sebana Cove, Kg Bkt

Raja and Kg Simon

Biological Environment

Overall Vegetation The project area currently consists of patches of mixed vegetation types comprise

of mixed forest vegetation and secondary regrowth. While, patches of

regenerating forest and an intact mangrove forest are recorded within 5km radius

from the project boundary. Generally vegetation types for the study area (up to

5km radius) are diverse recorded a total of 90 families and 251 species

Flora species Study on flora species within the project site and up to 5km radius from the

project boundary was conducted based on field survey. Within the project

site, a total of 48 families and 89 species are recorded. A comparison with a

list of endemic and rare species based on IUCN report and other relevant

studies show that the study area does not have any rare, threatened or

endangered species of flora

The total density of trees per hactare within the project site was 372

trees/ha (tree with diameter 10cm) with a volume of 86.9 m3/ha and a

biomass of 127.8 tons/ha. The carbon equivalent of this would amount to

about 60 tons

The total biomass and carbon stocks within the project site based on the

landuse patterns are estimated to be 77,928 tons and 36,626 tons

respectively. The total carbon dioxide that will be emitted from the land

clearing is estimated to be around 134,418 tons of CO2equivalent

Fauna composition

and habitat

Similarly fauna survey was conducted within the project site and the study

area

A total of 18 mammal species could potentially be found within the proposed

development area and a 5km radius surrounding it. However, only 11 were

observed throughout the survey, all of which are animal species commonly

associated with secondary forests and urban landscapes. Of these, eight are

categorised as protected species; the Common Treeshrew (Tupaia glis), Pig-

tailed macaque (Macaca nemestrina), Long-tailed macaque (Macaca

fascicularis), Dusky leaf monkey (Trachypithecus obscurus), Wild pig (Sus

scrofa), Asian palm civet (Paradoxurus hermaphrodites), Malay civet (Viverra

tangalunga) and the Lesser mousedeer (Tragulus kanchil), or locally known

as Kancil. The Asian small-clawed otter (Aonyx cinerea) is totally protected

under the act

A total of 14 species (five amphibians and nine reptiles) from 11 families of

herpetofauna were recorded during the survey. Of this total, only nine were

observed directly; six within the proposed development site and nine in the

surrounding area. The herpetofauna species found in the proposed sites are

all considered common species

A total of 142 species of birds were listed, 113 of which were observed

during the survey. Eighty-three-percent of these bird species are protected

under the Malaysian Wildlife Act 2010. Of the total 113 species seen during

the survey, 12 species are categorized as nearly threatened species. There

were also 19 migrant species recorded

Human Environment

Socio-economic Generally no settlement area is located within the proposed project site

except 10 families and 2 quarters which are located at the south-eastern and

southern border of the project site

A total of 24 village settlements, including Kg Sg Rengit are recorded within

5km radius from the project boundary

Socio survey was conducted in November 2012 to establish the social profile

of the study area and to gather perception and community attitude towards

the proposed project. A total of 150 respondents from 10 settlement areas

surrounding the project were interviewed. The survey also involved the 12

families located within the project site

From the finding of the survey, the level of acceptability (agreement) for the

proposed project development recorded at 68% and 66.7% respectively for

the respondent surrounding the project area and the 12 families who will be

directly affected by the project

Public Health The existing public health status of the community residing the vicinity of the

proposed project site was conducted via review and secondary data from

governmental published sources and health survey conducted together withsocioeconomic survey

Generally based on the finding of the survey, environmental sanitation of the

study area is satisfactory where hygienic toilet and safe drinking water

supply are provided however garbage disposal practises is found

unsatisfactory where around 75% are disposing their garbage in unhygienic

practises which may lead to foodborne and vectorborne diseases

Based on the 618 household member survey, hypertension (9.4%) is the

most highly recorded diseases diagnosed over the last one year. It is

followed by diabetes mellitus (6%). Other recorded diseases including

stroke, heart disease and breast cancer, recorded below 0.5% respectively

For the past 3 months from the survey date, high fever, cold/cough and

bloody sputum or cough were the common reason recorded for seeking

medical treatment

Besides the findings from the survey conducted, data on disease cases

related to air pollution, water pollution, animal vectors and reservoirs and

skin diseases were obtained from the patient records of the three health

facilities located within the vicinity of the proposed project site, namely

Hospital Kota Tinggi, Klinik Kesihatan Sg. Rengit and Klinik Kesihatan

Pengerang for a period of one year from January to December 2011. The

data is reported in this DEIA report

Traffic At present, the project site can be reached via the North-South Highway and

then Senai-Desaru Expressway to join to Road 92. Travel southbound along

the road will reach the project site on the right. At the end of the road will

reach a T-junction which link to Road 90 at the east and J52 at the west.

Road 90 can be used to access some tourism spots at Desaru. Meanwhile

J52 is the main road to Oil Yard Terminal for Dialog, Sg Rengit town and

other residential areas. Both of them are bi-directional road with single lane

A classified traffic count was carried out based on 5 classes of observed

vehicles were conducted on 21st -22ndDecember 2012 to capture existing

traffic situation on the road surrounding the project site. A total of 8 traffic

volume counting stations were established (2 at Road 92 and 6 at T-junction

of Road 92/90/J52)for morning, afternoon and evening peaks

Based on the finding of the traffic count, The main mode of transport at the

roads surveyed was private car/ taxi, followed by motorcycles, and then

vans/small lorries and lorries/tankers. Buses were the minimum traffic

composition, which accounted for less than 2% of the total traffic volumes

The following are the conclusions drawn from the traffic survey on the

existing conditions:

a) The level of service (LOS) from Kota Tinggi to Sg Rengit or Teluk Ramunia

or Pengerang and vice versa is labelled A indicating smooth traffic flow

without time delay during morning, afternoon and evening peak hours.

The results also showed that the capacity of the Road 92 is able to cater

to the existing volume of vehicles travelling on the road.

b) The traffic at the junction Road 92 / 90 / J52 has an B level of serviceduring morning and afternoon peak hours and C level of service during

evening peak hour indicating speed and manoeuvrability are more closely

controlled by the higher traffic flow.

c) The traffic at the road surveyed during weekend recorded slightly higher

volume of vehicle compared with week day.

d) Overall the traffic condition at Road 92 and the junction Road 92 / 90 /

J52 is considered stable. The freedom to select desired speed is relatively

unaffected.

E.10 Project Activity

The key project activities and potential environmental impact identified during the various development

stages of the proposed project development are presented as below:-

E.10.1 Pre-construction stage

The anticipated activity during the pre-construction stage principally involved project planning and study

which is typically non-environmental destructive. No significant adverse impact on physical and

biological environmental component is anticipated during pre-construction stage.

In terms of land acquisition, compensation and resettlement activities, social impacts are expected.

Land acquisition, resettlement (for 12 families identified) and compensation to the affected parties will

be undertaken by the State Government. Land acquisition matters, resettlement and compensation are

delicate issues that have to be handled with care and would have to be resolved before the site is

handled over to KPTC for construction commencement.

E.10.2 Project Construction Stage

The development of the proposed project will involve conversion of approximately 1,443ha of agriculture

and ex-mining land into industrial facility. The construction of the proposed project development is

anticipated to be completed over a period of 4 years from 2014 to 2017.

The activities anticipated during the construction stage includes:-

Land clearing, earthwork and site preparation works

Transportation activities includes transportation of heavy machineries and construction material

to the site

Construction of plant, installation of process equipment and development of associated

infrastructure and utilities

Construction and operation of workers camps

Due to the development of a huge land area and considerable significant construction period,

environmental impacts are anticipated on the following environmental component:-

Loss of vegetation

Soil erosion and sediment loading and effect to the water quality

Dust generation and effect to ambient air quality

Increase of noise levels due to construction vehicles movement and construction activities

Increase in construction work force leads to increase in regional economics activities as well as

increase in potential social conflict

Increase in regional traffic

Waste generation (biomass, domestic and construction waste)


25/40


________________________________________________________________________________________________________


While during the operational phase, due to the nature of the project which involves sophisticated

chemical process and long term operational period, potential environmental impact from the operational

stage of the project has been given greater emphasis in this DEIA process. The associated environmental

impact which is anticipated to be significant from the operational stage of the proposed project includes:

Associated impacts from the construction and operational traffic generation

Industrial risk due to handling and bulk storage of hazardous material and production process

Air quality impact due to emission from the flaring system, boiler stacks and other associated

gases emission from the refinery and petrochemical process

may lead to social cultural complication with the local

community

- Improper alotment of workers from different origin

within the same worker camp may post internal social

conflic

Minor Short term - Provision of accommodation within project

boundary

- Worker with different cultural background to be

housed separately to reduce social conflict however

common facilities is proposed to promote social

integration

3 Traffic Transportation of construction

material, machinery and

equipment and worker

generated traffic

- Material / equipment transportation is anticipated to

increase local traffic and bulky machinery

transportation may pose safety hazards to the existing

road user

- Traffic performance from Kota Tinggi to Sg Rengit/

Pengerang/ Teluk Ramunia and vice versa during

three peak hours is expected to slightly deteriorated

- Safety precaution signages should be erected at

area near to residential sites

4 Wastes Land clearing - Generation of 77, 930 tonnes of biomass wastes

- Some inert waste is expected from the demolition of

limited structures onsite however it is anticipated to

be insignificant

Minor Short term - Logging of tree with commercial value is proposed

to reduce biomass volume

- Solid waste collection system to be established for

domestic wastes generated onsite

Minor

5 Biodiversity Land clearing - Permanent loss of significant amount of biomass i.e.

around 78,000 tonnes in worst case of full clearing

however it is not significant in terms of species

protection values

- Removal of vegetation destroy the existing habitat and

migration of some fauna to the nearest vegetated area

is expected

- Impacts to the fauna is not significant since

herpetofauna and mammals within the site is poor in

diversity and less concern except the Asian small-

clawed otter which is c ommonly found near water

bodies

- There is also very little concern on reptiles and

amphibians and hence impacts will be minimal as

these animals will migrate once the area has been

disturbed

- Good number of avifauna (birds) observed within the

site however they are expected to take shelter and

depend more heavily on the adjacent forest and

therefore no concern

Minor Long term - Clearing to be limited within development area

only. If possible, restrict clearing at area reserved

for future development

hydrogeology,

soil erosion,

water quality

Land clearing - Annual erosion estimated at 191,501 tonnes/ha/yr for

uncontrolled earthwork. Under controlled earthwork, it

is estimated at 2,254tonnes/ha/yr which is about 81%

lower then existing annual erosion condition of 11,862

tonnes/ha/yr

Significant Short term - Sediment control basin to be installed within each

subcatchment as detailed in Section 8.3.4. It will

be used to reduce sediment loading and regulate

storm volume to the receiving rivers downstream

- Implementation of Best Management Practice

Insignificant if ESCP

is fully employed


30/40




- During uncontrolled earthwork, approximately

350,543 tonnes per storm event of sediment yield is

expected. It could be reduced to 9,855 tonnes per

storm event if c ontrolled earthwork applied. This will

result in around 52% lower than sediment yield for

existing condition

- Highest peak discharge appears during 15 minutes

storm event. The maximum incremental peak

discharges for all storm events are 24.9m3/s,

21.5m3/s and 58.4 m3/s for subcatchment of Sg

Lepau, Sg Kapal and Sg Rengit respectively. This may

cause flash flooding downstream

(BMPs) proposed for controlled earthwork for the

project is presented in Section 8.3.4.

- Scheduled clearing during dry season if possible

- Appropriate drainage system need to be

established for drainage of potentially encountered

groundwater during ground leveling works. This

temporary drainage system should form part of

ESCP

- Proper machinery maintenance yard to be provided

if maintenance activity to be conducted on site

- Proper storage and contaiment facility should be

provided for storage of fuel/hazardous material

onsite

Earthwork and constructionworks

- Cut and fill activity will disturb soil stability andincrease erosion rate

- Ground levelling at area between 5 to 15m are likely

to hit the groundwater table as the groundwater head

in most part of the site is simulated between 15 to

21.5m a.m.s.l.

- Potential leak and spill from machinery maintenance

change out ac tivity

- Potential spill and leaks from fuel / hazardous material

usage and storage onsite and this will cause loading of

contaminant into waterway and affects water quality

Minor Short term Insignificant

7 Air, Noise and

Vibration

Land clearing, earthwork and

construction activity

- Air and noise emission principally from machinery and

equipment used on site

- Construction noise predicted at 64.5 dB(A) and 58.5

dB(A) at a distance of 0.5km and 1km from the

1 Hydrological Change of stormwater

discharge from KPTC-MIRPD

- Highest peak discharges appear during 15 minutes

storm event. The maximum incremental peak

discharges for all storm events are 1.7 m3/s (Sg

Lepau), 50.2m3/s (Sg Kapal) and 659.5m3/s (Sg

Rengit). The incresases are significant and could lead

to flash flooding at downstream

Significant Intermittent - Diversion of runoff in accordance to drainage

design requirements as per Urban Stormwater

Management Manual (MSMA 2nd Edition), 2011.

- Approximately 0.7 ha of the existing pond at the

south-estern part of the project site will be

reserved to act as retention pond to cater largest

2 Air Quality and

Odour

Emission from the plant The predicted maximum incremental GLC for the tested

parameters during normal operation are as follow:

Parameter 1 hour 24 hour

TSP 1.1ug/m3(annual) 5.1 ug/m3

NO2 142.2 ug/m3 51.3 ug/m3

SO2 80.5 ug/m3 24.6 ug/m3

VOC 14.3 ug/m3(8 hours)

H2S 0.47 ug/m3(8 hours)

- With the above incremental, the predicted GLC of

pollutants are well below their respective standard

limit. Hence emission released from the identified

sources of the plant is predicted to have insignificant

impact to ambient atmosphere during normal

operation

- During abnormal operation, GLC for all parameters

analysed are predicted within the ambient limits

except for NO2which is above the limit at Kg Bkt Pelali

for 1hr averaging time and 24 hour averaging time at

Kg Rangkaian Bkt Buloh, Kg Rangkaian Sg Kapal, Kg

Bkt Buloh, Tmn Rengit Jaya, Kg Sg Kapal

- Overall, emission released from the identified point

sources is predicted to have insignificant impact to

ambient air quality during normal operation. While

during abnormal operation, only NO2is in concern at

the receptors as identified above

- H2S and VOC are the likely pollutant that may cause

odour problem. However, based on the air modeling

results, the low GLC of these pollutant are not

expected to cause significant odour impact

Insignificant Long term - Regular maintenance of point sources to ensure its

optimum operation and to comply with the

emission limit of new draft Clean Air Regulations.

- . In the event of abnormal operations involving

failure of process equipment, the related plant /

process should be temporarily shut down until it

resumes to normal operations. In the event of

pollution control failure, the related control device

should be repaired as soon as possible

- Minimize the frequency of routine maintenance

flaring via selection of reliable equipment and close

monitoring.

- Stack monitoring should be carried out as per the

requirement of new draft Clean Air Regulations.

- Effective scrubber and filter treatment to be

maintained to minimize H2S and VOC emission

from the stacks

- When neessary, odour control system such as

chemical scrubbing, chemical fogging or biofilter

should be installed at sewage treatment plant and

wastewater treatment plant

Insignificant during

normal operation;

Minor during

and northwestern towards Sg Santi and south and

southeastern direction towards Straits of Johor

- Based on the worst case scenario simulation with

500mg/l of BTEX as contamination sources over a

period of 30 years constant released rate, the

simulation revealed that movement of contaminant is

slow and takes 30 years to reach Sg Santi at the north

and Straits of Johor southwards

- As the sources of leaks from the onsite tank farm area

is located at southern part of project site, contaminant

movement northwards to Sg Santi is very unlikely

prompt area

- Emergency response for large oil spill and leaks to

be established

- Groundwater monitoring to be conducted within the

site and at the potential affected area principally

the particle path line area

- Existing public wells could be used for long term

monitoring purposes. However since all the public

well is located outsite of the project site (towards

the south of the project site) concerted effort from

JPDC and other relevant agency is needed to

establish an integrated monitoring network for the

area

considering

contaminant particle

path flow towards

north is unlikely

since tank farm

areas located at

southern part of the

project site

Change in groundwater

regime due to change of land

cover

- With an assumption of 70% reduction in groundwater

recharge, the impact on groundwater head and flow is

simulated to be insignificant

Insignificant Long term - Green area will be provided within the area

- Land which is not required for development will be

remained as its existing condition to minimise

disturbance (i.e. the hilly land at the northern

boundary)

- Some of the existing natural ponds within the site

will be preserved for storm retention purposes and

this serves as source of recharge

6 Socio-economic - Potential Employment

- Econmic opportunity and

income & revenue

- Demography, housing and

other services

- Socio-cultural

- Increase of employment opportunities for different

level of skills from skilled to semi-skilled workforce in

the plant

- Direct and indirect economic opportunity to the

community within the area is expected to increase

local income level

- The capital investment of the project is also significant

income to the relevant agencies via assessment fees,

taxes, etc

- Increase in population is expected to change the age

and sex structure of the local population

- Demand for housing and other local services including

community facilities is expected- In-migrant workforce may cause socio-economic mix

and lead to ethnic and social cultural conflict. This may

cause clash of lifestyles to the existing community

Significant Long term - Priority for direct employment of local labour

market and provision of training and scout for

deserving local scholar who study in the related

field to be fit into the plant workforce

- To optimize the full benefit of economic

opportunity, a well-planned industrial town with

supporting services to accomodate the working or

industrial population is necessary

- Sufficient housing by the private investor or

accomodation by the project proponent to house

workers

- Provision of sufficient public facilities by the state

government

- Promote equal opportunity to all parties in the

everyday doing and regular happenings in the local

area or impact zone so that health integration

within the existing community and in-migrant could

be established

Significant economic

benefit

7 Public Health

Impact

- Air emission from the

plants

- Effluent discharge from

the Wastewater treatment

plant

TSP, NO2, SO2, H2S and VOCs has been identified with

health hazards. Findings from the exposure assessment

indicated that the following:

- Under normal operation, GLC for TSP, NO2and SO2

well below RMAQG and H2S below AAAQG and hence

no impact to public health is anticipated

Minor during

abnormal

operation

Short term - Project operation of the releated plant is proposed

to be stopped within an hour in the case of an

abnormal project operation. The failed equipment

should then be repaired as soon as possible

- Monitoring of ambient air pollutant levels at the

proposed project site and at Kg. Langkah Baik, Kg.

Rangkaian Bukit Buloh, Taman Rengit Jaya and Kg

Minor and short term

(only during

abnormal operation)


34/40




- Durign abnormal operation, resident in Taman Rengit

Jaya is expected to be exposed to the threat of

NO2,but will be short term.

- During normal operation, HQ for H2S and VOC (as

benzene) at Kg Rangkaian Bkt Buloh are below 1,

hence it is still within the acceptable for human

exposures to non-carcinogenic risks of air pollutant

- Lifetime cancer risk for community exposure at Kg

Rangkaian Bkt Buloh to incremental VOC (as benzene)

is within acceptable cancer risk range of 10-6to 10-4

In terms of effluent discharges:

- No water intake downstream of Sg Rengit hence any

exposure will be via consumption- For accidental water ingestion while swiming as well

as through dermal intake, non-carcinogenic health

effect of water pollutants discharged into Sg. Rengit,

the HQ for zinc, silver, manganese, selenium and

chromium (VI) were all found to be below 1 and

acceptable

Rangkaian Sg Kapal should be conducted and

reported regularly once the project commences
