CHAPTER 1: INTRODUCTION

1.1 PROJECT TITLE

The proposed Project is:

The proposed masterplan development will hereafter be known as Kwasa Land development.

1.2 PROJECT DETAILS

The overall proposed new township masterplan development in Mukim of Sungai Buloh and Bandar Petaling Jaya, District of Petaling, Selangor will involve 2,291.29 acres of land formerly owned by Rubber Research Institute of Malaysia (RRIM). The overall size of the RRIM land is 2,624.37 acres and the remaining 333.08 acres of land has been surrendered for the development of the MRT Sg. Buloh Depot, MRT Station, MRT rail alignment and DASH Highway. The proposed development is located to the north of the Sultan Abdul Aziz Shah Subang Airport and is accessible via the New Klang Valley Expressway (NKVE), the Guthrie Corridor Expressway, North- South Expressway or Jalan Sungai Buloh.

As the southern portion of the overall development (under the jurisdiction of Majlis Bandaraya Petaling Jaya (MBPJ)) is in the midst of zone conversion stage, this Preliminary Environmental Impact Assessment is prepared for the northern portion development of 678.29 acres which is under the jurisdiction of Majlis Bandaraya Shah Alam (MBSA). The location of the development site is shown in Figure 1.1.

The proposed development comprises residential and commercial development with community amenities with a green and open space concept.

This PEIA submission will only cover the earthworks for master infrastructure facilities (hereafter referred to as construction phase) which will be limited to:

a. Major arterial and collector road networks i.e. all road networks reflected in the Master Layout Plan. b. All primary infrastructure utility land areas i.e. Water tanks, DCS (District Cooling System), to prepare the ground for the construction of these utility structures. c. All main drains, waterways and detention / retention facilities. d. Any river upgrading works as required by JPS. e. Some parcel developments for the purpose of borrow pits.

CHAPTER 10: CONCLUSION

The overall proposed new township masterplan development in Mukim of Sungai Buloh and Bandar Petaling Jaya, District of Petaling, Selangor will involve 2,291.29 acres of land formerly owned by Rubber Research Institute of Malaysia (RRIM). The overall size of the RRIM land is 2,624.37 acres and the remaining 333.08 acres of land has been surrendered for the development of the MRT Sg. Buloh Depot, MRT Station, MRT rail alignment and DASH Highway. As the southern portion of the overall development (under the jurisdiction of Majlis Bandaraya Petaling Jaya (MBPJ)) is in the midst of zone conversion stage, this Preliminary Environmental Impact Assessment is prepared for the northern portion development of 678.29 acres which is under the jurisdiction of Majlis Bandaraya Shah Alam (MBSA).

Based on the Environmental Impact Assessment study conducted, the proposed Project under the jurisdiction of MBSA will generate both beneficial and negative impacts during its implementation. During the earthworks for master infrastructure facilities, there are some minor environmental impacts such as water, air and noise pollution. However, these impacts are temporary and limited to the period of infrastructure works. In addition, implementation of the proposed mitigation measures would further reduce the significant level of the likely environmental impacts.

All the environmental issues identified will be taken into consideration at the early stage of the Project so that proper mitigation measures will be implemented to reduce or minimise the potentially adverse impacts. A monitoring program will also be established before construction begins to evaluate the impact of the construction work for the infrastructure works. The monitoring program shall outline the compliance reference of all proposed mitigation measures to ensure that adverse impacts on the environment are minimized.

The adoption of the recommended mitigation measures will provide the basic tools to ensure successful implementation of the project with minimum impacts.

CHAPTER 2: STATEMENT OF NEED

2.1 INTRODUCTION

The data and information were extracted from the following reports to support the rationale for developing the development:

 Tenth Malaysia Plan (2011 - 2015)  Structure Plan of Selangor (2006 – 2020)  Local Plan for Shah Alam City Council 2020

The viability to undertake the development is based on the following considerations:

Due to the burgeoning development in Malaysia in general and the Selangor State in particular, housing developers are compelled to expand their scope to the surrounding areas due to space constraint. There is a continual need for expansion away from the over congested city and town centre as the demand for housing is expected to continue to increase due to the expanding population as well as the growing number of new households. As the pattern of urbanisation is expected to persist, there is an urgent need to implement a controlled decentralisation of the urban conurbation.

The aim of the development is to optimize the existing landuse by developing the land into a new township for economic, commercial and residential purposes. The provision of adequate and affordable housing is an important aspect in enhancing the quality of life. The proposed mixed residential cum commercial scheme will be implemented based on the concept whereby housing will be provided with related facilities and services. The proposed development will also generate employment opportunities and therefore contribute to the economic growth of the immediate local area.

The national objective in regional development as underlined by the National Development Policy is to achieve balanced development between the regions. This balance can be achieved by distribution of income, health facilities, education, utilities, and recreation, social and economic opportunities. The implementation of the urban development strategy will reduce existing imbalance between the regions.

2.2 TENTH MALAYSIA PLAN (2011 - 2015)

In the Tenth Malaysia Plan, the implementation of housing development programmes focused on the provision of quality and affordable houses for all Malaysians. The planning and implementation of housing development programmes were based on the human settlement concept, which included the provision of public amenities. To enhance the quality of life and socioeconomic status of the urban population, efforts were undertaken to improve the quality of urban services as well as provide better infrastructure and public amenities.

To match demand for housing with supply, based on location and affordability, the affordable housing delivery system will be streamlined. To increase the quality of

Environment Asia Sdn Bhd 2-1 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

affordable new and existing housing, the efforts to deliver high quality and environmentally sustainable housing will be strengthened as this is the way to overcome the occurrence of weak quality control during construction and poor maintenance. To meet the call for environmentally sustainable design, housing design will have to incorporate green building design elements and technology. Thus, a healthy and sustainable housing industry will be cultivated.

According to the Plan, the requirement for new public houses is expected to be about 161,000 units. During the Plan period, Federal Government will construct new low-cost public housing for qualified individuals and it is expected in a total of 78,000 units across the nation. One federal agency will be responsible for federally funded housing instead of several ministries and agencies to increase the efficiency of housing provision.

Existing laws will be reviewed to deliver high quality and environmentally sustainable housing. In addition, housing providers will be accredited especially for the usage of skilled and qualified labour and construction process. Other than that, the introduction of Green Guideline and a Green Rating System will encourage environmentally friendly townships and neighbourhoods.

The strategic thrusts of housing development and urban services during the Plan period will be as follows:

 Encouraging urban rejuvenation through an en-bloc sale mechanism to ease the sale of collectively-owned developments;  Strengthening monitoring and enforcement to protect interests of house buyers on quality of housing construction;  Promoting the adoption of the Build-Then-Sell (BTS) approach;  Rehabilitation of abandoned housing Projects.

Thus, this shows the proposed development is in line with the Tenth Malaysia Plan to cultivate a healthy and sustainable housing industry.

2.3 STRUCTURE PLAN OF SELANGOR 2020

It is important that the Project development falls in line with the local plan to ensure it will contribute and not hinder the overall development of the Selangor State. The Project site‘s location falls within the Petaling District of the State of Selangor. Selangor Structure Plan 2020 was used to gauge the suitability of the development. Overall, the main aim of the Selangor Structure Plan is to ensure an overall integrated and sustainable development of Selangor in line with the State‘s vision by the year 2020. This development would include economical, physical and environmental, and social development.

The physical development of any area within the State of Selangor will be largely dependant on which zone the location of the development falls under. The development location falls under Zone A categorized for development of industrial, institutional, residential, commercial, administration and services facilities (Figure 2.1). It also falls under the Klang Valley Zone (Zon Wilayah Lembah Klang- Figure 2.2) with a development strategy that aims to increase the quality of life for city residents and also to

Environment Asia Sdn Bhd 2-2 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

increase the quality of the environment through integrated public transport service, Travel Demand Management, world class infrastructure and the greening of city centres. The development strategy also emphasizes in raising the level and quality of urban services provision to support the output distribution of economic development and the placement of residents in the Klang Valley Zone.

The scope of this development will involve residential and commercial development with community amenities with a green and open space concept, which will accommodate a population equivalent (PE) of 225,000.

In the scope of the residential development, the Petaling District already comprises the majority of housing units in Selangor. Even so, the need for residential units is estimated to rise to 496,747 units in the year 2020 from 280,756 units in the year 2005.

The same trend can be observed for commercial component. This main contributor to the economy is expected to experience rapid growth within the year 2005 to 2020. Within this time span, commercial areas in the Petaling District are expected to expand from 7,212,903 m2 to 13,443,309 m2 of floor space.

Therefore, in line with the local plan, active steps need to be taken to ensure that the residential and commercial needs are met in a sustainable manner.

It can be concluded that the residential and commercial components are inter- dependable. Therefore, the development of these two components with the proper infrastructure and attractions to support it is of utmost importance to achieve a balanced development in the State of Selangor.

2.4 LOCAL PLAN FOR SHAH ALAM CITY COUNCIL 2020

Based on the Local Plan for Shah Alam City Council 2020, the Project site falls under Blok Perancangan Kecil 1.5 and has been zoned as institutional as the site is located on the Rubber Research Institute of Malaysia (RRIM) land (Figure 2.3). However, approval for the landuse conversion to mixed developments has been obtained from Majlis Bandaraya Shah Alam. The RRI land was agreed to be developed as a mixed development to support the MRT line by the State and Federal Government (Figure 2.4).

There will be 5,452 units of medium, medium high density and affordable housing to be built on the proposed site under the MBSA portion. A total of 134.19 acres of the development site will be allocated for commercial development while another 104.81 acres will be allocated for mixed use plots. Approximately 46.00 acres will be allocated for landscaping purposes, which includes linear park/green area while 33.62 acres will be allocated for the retention ponds. Adequate provision of facilities is an integral part of the proposed development. A total of 207.41 acres of land has been set aside for the construction of electrical substations (PMU), water tanks, suction tank/pump house, pump station, ICT hub, water quality treatment, district cooling and gas house. Community amenities will cover 48.01 acres which will include primary schools, secondary school, mosque, worship place and integrated Islamic school.

3.2 DEVELOPMENT CONCEPTS

The main concept of the development is to create a new focal point that reflects the township of 21st century; one that is Green, Connected, and Inclusive and has a sense of Place Making. The Kwasa Land development shall face the challenge of competitiveness, as new townships emerged within the greater Kuala Lumpur region. Thus, the Kwasa Land development shall provide a total solution to urban living where it will offer quality living environment in its true essence. The Township shall create a livable city where the values of safety, health, connectivity, high environmental quality, great urban design and built environment, access to work and Medicare, affordable and having choices for places to live and a vibrant economy shall be embedded in its master plan design.

The concept applied in determining the landuse and arrangement of the components within the development site will take into consideration the various aspects as follows:

i) The type of development that is taking place in the areas surrounding the development site. This is taken into consideration to avoid potential conflicts and negative effects that could hinder the implementation of the development. ii) Provide sufficient public facilities and infrastructure for the comfort and convenience of the residents. iii) Maximize and optimize landuse that has high commercial value and development cost. iv) Placement of the development components will exploit the interesting visuals while taking into consideration the safety aspects v) Provide a systematic and safe road network within the site.

The Kwasa Land development shall focus on 8 key design principles that abide by the laws of nature, where built environment shall co-exist with natural environment and optimizes land utilization. The eight design principles that influence the plan are:-

 Principle 1: Protect the site’s ecology by creating an urban bio diversity that respects natural flood plains and the site’s natural features;

Environment Asia Sdn Bhd 3-4 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) -MBSA

 Principle 2: Preserving heritage values and creates places for people–parks and recreational areas;

 Principle 3: Providing connectivity and ensuring public accessibility and permeability;

 Principle 4: Creates catalyst type of development, speeding up growth and enhancing local economies.

 Principle 5: Creating Communities that has choice in housing types and addresses affordability.

 Principle 6: Developing a green infrastructure master plan that shall contribute towards environmental quality;

 Principle 7: Managing landuse and urban growth through a flexible plan that is practical and attractive for investment; and

 Principle 8: Creating a sustainable township that is green holistically and a master plan that is integrated in its design solutions.

3.3 PROJECT SCHEDULE AND CONSTRUCTION

The actual earthworks for the infrastructure works of the northern region will begin in February 2015 and to complete by 2018.

Environment Asia Sdn Bhd 3-5 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) -MBSA

3.4 INFRASTRUCTURE REQUIREMENTS AND DEVELOPMENT

3.4.1 Water Supply

Syarikat Bekalan Air Selangor Sdn Bhd (SYABAS) is responsible for the water supply distribution in the State of Selangor.

The overall total demand for the proposed development is estimated to be 13.5 million gallons per day. The water demand for the development was based on the estimated population equivalent of 225,000. The water supply distribution and reticulation works for RRIM will be divided into two catchments of North and South demand (with Jalan Sungai Buloh as the dividing line) with one unit of suction tanks provided at either catchment. Under this division, the water demand will be 5.8 million gallons per day and 7.7 million gallons per day, respectively. The development is further subdivided into six water demand catchments where each catchment will be served by their own sets of water reservoir tanks.

Based on preliminary discussions with SYABAS officers, due to the high demand, the source of water supply for RRIM is to be obtained directly from Matang Pagar Balancing Tank, approximately 15 km north of the development site near Ijok. Hence, a new 1200mm Ø CLMS pipeline will need to be laid over the above distance to the Project site.

One suction tank will be provided for each of the north and south catchment.

3.4.2 Sewerage System

The total generation of wastewater for the development is estimated to be 5,062,500 liter per day based on a population equivalent (PE) of 225,000. The estimation is based on the

Environment Asia Sdn Bhd 3-6 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) -MBSA

recommendations by SIRIM (Malaysian Standard: Code of Practice for Design and Installation Sewerage System, 1991) whereby the generation rate per capital per day for wastewater is 225 liters. The generation of wastewater will be pumped to the main sewage treatment plant, maintained by Indah Water Konsortium.

Only one STP has been provided for the overall development as required by Indah Water Konsortium (IWK). The STP will be located at the southern portion of the development which is under Majlis Bandaraya Petaling Jaya (MBPJ).

At most areas, sewerage flow shall be via gravity flow. The maximum allowable depth set for manhole is 6m deep. At areas where manhole depths exceed 6m, intermediate pumping stations is introduced to lift the flow to the following line. Sewerage pipe material for gravity flow will be of Vitreous Clay Pipe (VCP) and minimum pipe diameter is set at 300 mm pipe size, laid at minimum 1:350 gradient. Manholes will be provided at every 80 m distance length, change in pipe diameter and gradient and at every directional change.

Figure 3.3 shows the sewerage reticulation and treatment works for the proposed development.

3.4.3 Roads

The major road networks such as North South Expressway, Guthrie and North Klang valley Expressway form an excellent main grid around the proposed development, Damansara – Guthrie. This main grid is supported by major access roads such as Jalan Sungai Buloh and Jalan Lapangan Terbang Subang. Alternative access such as Persiaran Mahogani, Persiaran Surian and Jalan Teknologi will be the main access from Kota Damansara into the development site.

The hierarchy and classification of road reserves within the proposed development are divided into:

Environment Asia Sdn Bhd 3-7 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) -MBSA

Concealed roadside drains will be provided under the road shoulders and incorporated as pedestrian /cycle path. Color pavement treatment shall be considered for bicycle lanes to avoid potential conflict between bicycles and vehicles.

In line with the development's concept of enhancing connectivity, wide pedestrian walks are provided (which double as cycle tracks) to encourage use of public transport and reduce private vehicle usage. All kerbs and shoulders will be designed at a low height with ramps and fitted with road furniture for the ease of cyclists and those on wheelchairs and with strollers.

Landscape strips will be located between the carriageway and pedestrian walk:-

a. to avoid indiscriminate vehicles parking on road kerbs; b. to act as a 'soft barrier' between traffic users and pedestrian; c. to allow continuity of pedestrian movement at road junctions; where the turn in radius encroaches into landscape area; d. to double as utility strip and signage locations.

Figure 3.4 shows the road network within the proposed development.

3.4.4 Drainage System

In this development, main drains reserve and detention pond system is proposed for the development area. Stormwater will be channeled by drains within the development site into 16 detention ponds (4 detention ponds under MBSA and 12 detention ponds under MBPJ) and by using a “controlled at source” and detention concept before draining out into the main drain reserve and subsequently into the existing Sg. Damansara and / or JPS retention pond. The primary function of these facilities is to reduce peak discharge by temporary storage and gradual release of stormwater runoff by way of an outlet control structure (overflow weir/ outlet pipe). The geometry of the ponds, subject to site condition, can be either part-circular or irregular shape.

As this development is planned to become a showpiece of the new management concept using Sustainable Urban Drainage System (SUDS), integrated stormwater management approach will be fully adopted in formulating Stormwater Drainage Master Plan for the township development and to meet the technical requirements of the Urban Stormwater Management Manual for Malaysia (MSMA) in all drainage design. One of such system used is the Bio-ecological Drainage System (BIOECODS).

The BIOECODS is a stormwater drainage system designed with the concept of SUDS and fully complies with the MSMA requirements. The BIOECODS will be discussed in detail in Chapter 6.

The proposed drainage system for this development shall be designed to cater the following:

a. Capture and channel stormwater runoff from within the developments catchment b. Receive and channel stormwater runoff from the upstream developments c. Enhance / upgrade the existing natural waterways d. Enhance / upgrade the existing water bodies

Environment Asia Sdn Bhd 3-8 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) -MBSA

The types of drains to be adopted for the development are:-

a. Concrete lined box drain as road side drains; b. Composite drains of concrete lined U-drain and grass lined trapezoidal section as main drains; c. Engineered swales and Bio-Eco Drains (as main drains) at low density areas.

3.4.4.1. Minor System

The minor system is intended to collect, control and convey runoff from buildings, infrastructure and utilities in relatively frequent storm events to minimize inconvenience and nuisance flooding.

a. Road Side Drain

The road side drain systems shall consist of concealed concrete lined box culvert with inlets or grasses swale along road kerbs, in line with the local council’s minimum guidelines. A concealed system was chosen to allow the roadside kerbs to double as pedestrian walkway hence providing connectivity throughout the development. The roadside drain systems shall be designed to Design Storm 10year ARI.

b. On Site Storage

On-site stormwater detention (OSD) involves the temporary storage and controlled release of stormwater generated within a site to a predetermined rate. In general, on-site storage is a small storage constructed on individual residential and commercial lots.

3.4.4.2. Major System

The major system is intended to safely convey and control runoff collected by the minor drainage system to the larger downstream systems and water bodies.

a. Main Drain

All roadside drains or minor drain shall flow into the downstream main drains where the runoff will be conveyed into detention system downstream. The proposed main drains shall be OF PRECAST RC - Box culvert type. A primary treatment facility such as gross pollutant traps (GPTs) which is required for the main drain will be considered as part of a “treatment train”.

b. Retention / Detention Systems

Retention and detention systems will be provided at all downstream locations of drain networks for the respective catchments.

Existing downstream waterways identified to receive the discharge from these ponds are Sg. Damansara and JPS retention pond. The retention / detention systems shall be designed to hold runoff for the design storm 100 ARI for a duration of the design

Environment Asia Sdn Bhd 3-9 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) -MBSA

catchment’s design storm. The permissible discharge from the storage systems shall be at a pre-development design flow for ARI 2 years.

Overflow facilities will be sized to allow post-development discharge of 50 years design ARI. For detention / retention systems discharging directly into a running water body i.e.

Sg. Damansara, weirs sized to post – development Q100 will also be provide.

For a satisfactory distribution of flow across the pond, the length to width ration shall be at minimum 3-5.

All detention ponds shall have a permanent standing water of minimum 0.6 m and maximum 1.5 m. Edge slopes shall be designed to a 1: 4 or 1:6 to provide bank stability, safety to children wading and to encourage habitat for water plan growth.

EXTENDED RETENTION LEVEL

Gross pollutant traps shall be provided at various stages; upstream and at all inlets to remove litter debris and coarse sediments. Where space is available, constructed wetland will be provided instead of the GPTs.

Inlet structures shall be distanced away from the outlet to maximize retention time and to ensure the entire water body is utilized for pollution control.

3.4.5 Electrical Requirement

The electricity demand within the development site will be supplied by Tenaga Nasional Berhad (TNB). Based on the electrical load estimation, two units of Transmission Main Intake (PMU) will be constructed within the proposed northern development site.

3.4.6 Telecommunications

The total number of telephone lines required for the residential area is 8,373 lines based on an average of 1.5 lines per residential unit and 16,000 lines based on 3 lines per commercial unit. The telephone lines will be supplied from the existing Telekom line along Jalan Sungai Buloh. This main TM cable is from Ibu Sawat Bandar Baru Sungai Buloh to Kota Damansara. Telecommunication system will be using fiber optic cable for high speed broadband services and integrated with Information and communication Technology (ICT) system. Manhole and ducting will be provided by the sub-developer.

Environment Asia Sdn Bhd 3-10 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) -MBSA

3.4.7 Gas Infrastructure

There is a Natural Gas pipeline along Jalan Sungai Buloh, Route 15 bordering the development site. The Natural Gas pipeline belongs to Gas Malaysia Sdn Bhd. Gas infrastructure will be provided by Gas Malaysia depending on the demand from the development. A gas house will be required at the northern section.

3.4.8 District Cooling System

It is estimated that the development under MBSA will demand 119,496RT of cooling capacities. To cater for this demand, it is proposed that centralized cooling plant to be built for the development. For this, it is proposed that the development to have one district cooling plant serving the northern sector (MBSA).

3.4.9 Solid Wastes

The amount of solid wastes generated by the proposed development is estimated using the population equivalent. The total amount of solid wastes produced is estimated based on a generation rate of 0.5 kg/person/day. Based on the estimated population equivalent of 225,000 PE, the total amount of solid waste produced is estimated to be 112,500 kg/day.

3.5 EARTHWORKS DETAILS

The development site would require the land to be leveled for infrastructure works which will include roadworks, detention ponds, main drains and roadside drains and platforming (related to access roads).

The estimated total amount of cut is 1,120,000 m3 and the estimated volume of fill is 998,000 million m3. However, based on the bulking factor (increase off cut volume created by excavation) and shrinkage factor (decrease in fill volume due to compaction), the cut and fill volume will be balanced. There will not be any disposal of access material required. The breakdown of the cut and fill volume for the development is shown in Table 3.6.

Table 3.6: Breakdown of Cut and Fill Volume

DEVELOPMENT COMPONENT CUT VOLUME (m3) FILL VOLUME (m3) ROADWORKS 520,000 610,000 DETENTION PONDS 240,000 30,000 MAINDRAINS AND ROADSIDE DRAINS 100,000 8,000 PLATFORMING 260,000 350,000 TOTAL 1,120,000 998,000 Cut and fill embankment reserves are to be sized to the following recommendations:

Boundary Slopes and Internal Slopes  Cut slope - 1 V:1.5 H  Embankment Slope - 1V:2H

Environment Asia Sdn Bhd 3-11 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) -MBSA

In general, material from cut areas of the site if acceptable as fill material shall be used throughout. However, should peat soil be encountered, it shall be excavated and replaced with granular material. Removal and stockpiling of topsoil for future use shall be carried out in stages to keep uninvolved area undisturbed. Filling material shall not be laid on top of debris left over from land clearing. The standard of compaction to be achieved shall be in accordance to BS 1377 where in situ sand replacement method shall be used to determine the density of the soil. The level of compaction to be ascribed to shall be as follows:

 Compaction shall be specified at 90% maximum dry density at optimum moisture content for all layers.  Elsewhere, shall be 95% of the maximum dry density at optimum moisture content for the last three layers of fill.

All earthworks shall be carried out in accordance with the recommendations in the British Standard BS 6031:1981 Code of Practice for Earthworks.

CHAPTER 4: DEVELOPMENT OPTIONS

4.1 INTRODUCTION

The options comprise the following:

i) No development – area retained as rubber plantation ii) Site option iii) Development option iv) Development component option v) Construction method option

An assessment of the above options is made against the following criteria in order to decide the most acceptable option for development of the area. These include:

i) Environmental acceptability ii) Social and economic value in terms of employment opportunities, social impacts and contribution to the economy iii) Landuse compatibility iv) Relevance to government policy and development strategy for the area

The merits and demerits of each of the options are discussed below.

4.2 NO DEVELOPMENT OPTION

In the event that the “No Development” Option is taken, the proposed Project site will be left as a rubber estate.

The consequence from this option will inevitably lead to the loss of urban progress from both the economic and social aspects. Opportunities from urban progress in the form of employment opportunities and revenue generation to the local community and state government will be lost. Downstream benefits generated by the construction sector will also be negated. Although the “No Development” option will remove the possibility of significant change for now, this does not guarantee the site will remain undeveloped in the future. In view of the entire development, it is unlikely that the site will remain unchanged in the long run. As the development of the northern region is part of the overall development of Kwasa Damansara of 2,291.29 acres, the “No Development” option will hinder the development in totality and this may consequently affect the overall initiation of the development as a whole.

Choosing the “No Development” option will also hamper the potential of the proposed development as new residential neighbourhood area as it is strategically nestled between major residential areas surrounding the Project site to the north, east, southeast, southwest and northeast.

The larger implications of the “No Development” option should also be taken into consideration. The “No Development” option will cause the area to lose out in various

Environment Asia Sdn Bhd 4-1 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

economic growth aspects. If the “No Development” option is chosen, the benefits associated with employment and economic growth will be denied. On all accounts, such an option will be out of line with the local authorities’ plans for the area and the Government’s Plans towards vision 2020.

4.3 SITE OPTIONS

Sungai Buloh is one of the fast growing urban areas in the region with the introduction of many housing estates in the area to meet the increasing demand from people working in the adjacent urban areas. The strategic location of Sg. Buloh to the highly developed urban areas around Kuala Lumpur and Selangor such as Damansara and Shah Alam is a great advantage as it makes the area highly accessible through various highways available.

With a land size of 678.29 acres, the land provide many great opportunities for development and has been identified as one of the mega projects to be developed under the Greater Kuala Lumpur Strategic Development, an initiative under the 10th Malaysian Plan to stimulate growth in the region.

Based on the Local Plan for Shah Alam City Council 2010, the Project site falls under Blok Perancangan Kecil 1.5 and has been zoned as institutional as the site is located on the Rubber Research Institute of Malaysia (RRIM) land. However, the land is now gazetted to residential and mixed developments by the State and Federal Government. The RRI land was agreed to be developed as a mixed development to support the MRT line by the State and Federal Government.

Implementation of the development will provide opportunities to fulfil the high residential and commercial demand due to the expanding population. The development will also improve and further enhance the surrounding aesthetic value, infrastructure and utilities of the local area. All this will offer a better quality of life. The option to develop will help to partially fulfil the additional housing needs, commercial, public utilities and increase employment opportunities as envisaged in the Sungai Buloh- Petaling area.

4.4 DEVELOPMENT OPTIONS

The following sectoral options are also considered:

i) Residential development ii) Commercial development iii) Recreational development iv) Industrial development v) Agricultural Development

4.4.1 Residential Development

In terms of economic viability, there is a demand for housing facilities within Sungai Buloh, Subang, Kota Damansara and Shah Alam area. The site is located near well-

Environment Asia Sdn Bhd 4-2 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

populated residential and commercial areas. In terms of environmental sustainability, the residential development will not pose any long-term water, air or noise pollution to the surroundings. The residential option is also socially acceptable as most of the adjacent areas contain residential development such as Kampung Baru Sungai Buloh, Kota Damansara and Subang Bestari. In addition, the development will be providing good quality residences and infrastructure facilities, in line with the aims of the Tenth Malaysia Plan to provide quality housing. The recreational facilities such as linear park and green area being planned by the Developer is also compatible with the ultimate aim of the Tenth Malaysia Plan, which is to meet the call for environmentally sustainable design for housing design.

4.4.2 Commercial Development

Similar to a purely residential area, a purely commercial area will find it hard to prosper as the area is located near other commercial areas to the north, east, southeast, southwest and northeast. The shop lots within Bandar Baru Sungai Buloh (north), Sunway Giza, The Strand, Dataran Sunway, Sunsuria Avenue, Mutiara Damansara and the surrounding area in Kota Damansara (east), commercial centers within Ara Damansara area (southeast), Subang Permai commercial center (southwest) and the Taman Sains Selangor which comprises of factories and commercial centers is deemed sufficient to cater for the local residents’ needs. Other concerns would be of economic viability, due to the competition posed by the established commercial centers nearby.

4.4.3 Recreational Development

The surrounding area had been saturated with many existing golf and country clubs. Tropicana Golf & Country Resort, Sri Selangor Golf Club and Bandar Utama Golf Course are located at the southeast region from the Project site while Saujana Golf and Country Club and Glenmarie Golf and Country Club are located further south from the site. Sultan Abdul Aziz Shah Golf Club is located at the southwest region. Hence, further proposal of golf course is deemed not suitable.

The preservation of the remains of Sungai Buloh Forest Reserve, known as Kota Damansara Community Forest Park for recreational activities would be much preferred.

4.4.4 Industrial Development

The industrial development is not suitable for the Project site as it will result in a combination of water, air and noise pollution to the nearby existing residential areas. Although the industrial option may provide employment opportunities to the local residents, the potential impact in terms of pollution and traffic as a result of its activities may affect the local population socially. Furthermore, the surrounding area already has industrial development such as the Kampung Jaya Sungai Buloh industrial area to the north and Taman Industri Sungai Buloh to the east.

4.4.5 Agricultural Development

The most likely scenario for agricultural development will be similar to “No Development” option whereby the site will remain as a rubber estate. An agricultural development of the

Environment Asia Sdn Bhd 4-3 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

Project site would be a waste of valuable land resource as the Project site is located on prime land in a densely populated suburban centre and possess a high inherent value. The agricultural option would also be an unlikely source of local employment, as most urban residents prefer to work in commercial and industrial centres rather than involving themselves in the agricultural sector due to its lower wages.

4.5 DEVELOPMENT COMPONENT OPTIONS

4.5.1 Obstacle and Restriction

4.5.1.1 Industrial area

Some light and medium industries of Sg. Buloh are located at the northern and the eastern side of the Project site boundary. The development components shall take into consideration of the impact resulting from the industrial areas. These impacts will include air and noise pollution. The Project proponent has already taken this into consideration in the master plan development whereby commercial plots and mixed use plot will be sited adjacent to the industries while residential areas are located further away.

4.5.1.2 MRT Depot, Line and Stations

The MRT Depot is located at the northern boundary of the Project site. The MRT track as well as the stations (Station Kota Damansara and Station Taman Industri Sg. Buloh) may cause noise nuisance within the development as the track runs through the development area under MBSA. Issues such as noise pollution were included in the master plan design. The assessment of noise impact from the depot area to the development was carried out and detailed out in Chapter 6 and Chapter 7of this EIA Report.

4.5.1.3 Subang Airport

Sultan Abdul Aziz Shah Airport is located further southwest of the Project site. The location of Sultan Abdul Aziz Shah Airport limits the type of development in the areas surrounding it. This places restriction on the height limit and the noise levels due to air traffic. The plan view of the development area that incorporates the obstacle limitation surfaces for Sultan Abdul Aziz Shah Airport will be discussed in Chapter 5.

4.6 CONSTRUCTION METHODS OPTION

The present construction method for the site will be to develop the required infrastructures (roadworks, detention ponds, main drains and roadside drains and platforming) for the northern region development. The individual phases of the development shall not be cleared and will be left in their original condition. Once the phase is purchased or acquired, only then will the area be cleared and prepared for structural work of the desired component identified in the master plan concept.

Environment Asia Sdn Bhd 4-4 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

4.7 THE PREFERRED OPTION

The preferred option should ultimately be an option that will not only blend into but enhance the surrounding environment. In this case, a residential development and commercial development with the green concept will be suitable for the existing site, as there are already established and well-populated residential areas nearby.

The option to develop the Project site as a residential and commercial development will be economically beneficial, as there will be significant financial gains from the sale of properties. The residential option will also benefit the State Government in terms of revenues from taxes, and is compatible with the aims outlined in the Tenth Malaysia Plan which is to provide good quality housing.

In addition, the Project will fit into the developer’s intention for the overall development of Kwasa Land development where the development of the northern region will be followed up with the southern region (Refer Figure 3.1).

Therefore, looking at the current social and economic potential of the Project site and its surroundings, the proposed Project fully satisfies the residential needs of the area and will be an appropriate choice.

A summary of the options is shown in Table 4.1.

4.8 ENVIRONMENTAL COST & BENEFITS

4.8.1 Introduction

An attempt has been made at costing, in financial terms, of the impacts resulting from the Project. There are, however, certain impacts which cannot be realistically costed. In determining the environmental costs and benefits, the opportunity cost is an important consideration. It represents the benefits that could not be derived from any alternative use of the area should the Project not be undertaken.

If more revenue (benefits) can be derived from the proposed Project as compared to the current landuse, then this will represent the opportunity cost. It is not within the ambit of this EIA to access the economic and financial viability of the Project. The environmental valuation provides comparison of environmental cost and benefit to be addressed in this manner.

4.8.2 Costs

The principal environmental cost is derived from the utilization of natural resources and the provisions of amenities. The main ones are:

- loss of rubber estate - alleviating damage that could arise with the development of the land - provision of amenities / utilities to upgrade the existing conditions

i) Loss of rubber trees

The revenue that is expected to be lost from the clearing of the rubber trees will be largely depending on the price of the rubber tree commodity which ranges from around RM 5.12 to RM 6.38 per pound. However, the land is now converted to mixed development by the local authority to support the MRT line and the surrounding area by the State and Federal Government. In regards to the loss of flora and fauna, there are no endemic or endangered species and as such, there are no potential costs.

ii) Alleviating Damage from Development of the Land

In terms of the environment, the most important cost will be in terms of the amount that will be spent on provisions of silt traps, drainage and catchment pond to prevent and reduce silt from entering the receiving waterways and to maintain the status quo of the environment so far as the air and water quality is concerned.

4.8.3 Benefits

What represents a cost to the developer could also generally be a benefit to the local business, the local community and the State Government. Benefits, like costs can also be divided into two categories, namely, financial and intrinsic. The intrinsic value will be the potential increase and improvement of social infrastructure from the utilities provided by the Project while the financial benefit is in local investment and business and job opportunities in the Project site.

Environment Asia Sdn Bhd 4-6 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

The tangible financial benefits from the Project are expected to be directed to local population and business and the State and Federal Government.

The benefits to the Project Proponent are not considered here because it is assumed to be positive considering that a substantial amount will be invested in the development. Financial benefit to the State / Federal Government is based on an estimate of the projected increase in economic growth as follows:

i) Increase in direct revenue ii) Sustainability of incomes iii) Increase in land values iv) Socio-economic cost and benefit

i) Increase in direct revenue

There will be an increase in revenue to the State Government through collection of annual quit rent and land assessment.

The development will create new employment, opportunities for business, better amenities, utilities and other community facilities. Indirectly, the standard of living in the area will be better with higher incomes.

ii) Sustainability of incomes

Recurring incomes to the state and federal government will be obtained from:

- annual quit rent and land assessment from the development - direct and indirect taxes from properties in the area

The direct taxes will be in the form of income tax, service tax and capital gains tax in the development area and company taxes from the services establishments. Indirect taxes will mostly be in the form of goods and services tax.

iii) Land values

With the Project, land values will invariably increase due to increased utilization of land, better facilities and amenities. This feature is considered an economic benefit and can easily be translated into a financial asset.

In terms of land cost, agricultural land in the area are valued at about RM 1 million per acre depending on land status, ownership, size, location and proximity to facilities. When such land is converted to residential and commercial uses, the value will increase. Thus, there is this value-added consideration in developing the area.

iv) Socio-economic cost and benefit

Socio-economic costs and benefits to be derived are summarized in Table 4.2.

Environment Asia Sdn Bhd 4-7 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

Table 4.2: Socio-Economic Costs and Benefits

ENVIRONMENTAL AND ECONOMIC GAINS AND LOSSES FOR THE COMMUNITY QUANTIFIABLE NON-QUANTIFIABLE

A. BENEFITS A. GAINS 1. Employment 1. Economic history - Creation of jobs - Diversification of local economy - Changes in occupational distribution 2. Landuse and diversification - Existing land values increase 2. Accessibility 3. Improved local economy

4. Increase in income levels - Average per capita income increases - Additional income

5. Provision of additional housing

B. COSTS B. LOSSES 1. Increase in cost of living 1. Reduced social stability due to change in sociability / friendliness 2. Induces inflation and reduces real wages 2. Traditional community roots and identity may be lost

4.8.4 Summary

The cost-benefit evaluation attempted here is open-ended due to the many unquantifiable factors involved. If the area is left in its present state, the revenue accruing to both the State and the local population will be much lower than if it were developed. This is because the opportunity cost will not be realized.

CHAPTER 5: THE ENVIRONMENTAL SETTING

5.1 INTRODUCTION

The existing environment in terms of its physical, biological and socio-economic components is necessary to be comprehensively described through information obtained from field surveys and baseline monitoring in order to assess any potential impacts arising from the Project.

The potential impact area is defined as the area within a 5 km radius from the boundary of the Project site. The assessment of the potential impacts arising from the Project site will be focused within this 5 km radial area.

5.2 PHYSICAL ENVIRONMENT

5.2.1 General Description

The overall proposed development is located on Lot 73534, Lot 73533, Lot 2288, Lot 73532, Lot 73530, Lot 73531, Lot 4080, Lot 73603, Lot 73605, Lot 2822 and Government Reserve (Road Reserve, Water tank and Pipe reserve) in Bandar Petaling Jaya, Daerah Petaling, Selangor. The Project site occupies Lot 73534, Lot 73533, Lot 2288 and Lot 73532 with an area of about 678.29 acres. The site is accessible via the New Klang Valley Expressway (NKVE), the Guthrie Corridor Expressway or Jalan Sg. Buloh.

5.2.2 Topography and Slope Analysis

The topography of the development site is characterized by sloping and undulating land terrain. The elevation of the overall development of 2,291.29 acres ranges from 9 m to 119 m above mean sea level (Figure 5.1). Based on the slope gradient map which was prepared by Max Engineering Consultant, the overall site is predominately categorized as slopes of Class I and Class II. 88.76% of the site is located on Class I, 8.39% on Class II and 2.08% on Class III while 0.77% consists of man made slope. The slope gradient classification is summarized in Table 5.1 while construction suitability classification for the development is summarized in Table 5.2. Figure 5.2 shows the slope gradient classification for the overall development of 2,291.29 acres while Figure 5.3 shows the construction suitability map.

The elevation of the site for northern region ranges from 24 m to 62 m above the mean sea level where the higher levels are mostly found at the eastern part of the Project site. Based on the slope gradient analysis, the proposed northern development is predominantly categorised as slopes of Class I.

The approval letter from Jabatan Mineral dan Geosains for this development is attached in Appendix 1.

5.2.3 Hydrology and Streamflow

The site is located within the Sg. Buloh and Sg. Kelang catchment area (Figure 5.4 and Figure 5.5). The overall development site is drained by seasonal natural waterways of Sg. Paku, Sg. Payong and Sg. Takit and the streams of Sg. Rumput and Sg. Kedondong. The northern development site (under MBSA) is only drained by Sg. Kedondong and Sg. Payong. Sg. Payong is a seasonal natural waterway which is dry during the dry seasons.

Sg. Kedondong will flow into Sg. Buloh and subsequently into the Straits of Malacca while Sg. Payong will flow into Sg. Damansara (southern development) and subsequently into Sg. Kelang and eventually into the Straits of Malacca.

There are no water intake points located downstream of the Project site within the Sg. Buloh catchment area and Sg. Kelang catchment area. The nearest water intake point is at North Hummock WTP which is located about 10 km at longitude 101028’48” E and latitude 3010’00”N as shown in Figure 5.4 and Figure 5.5.

Environment Asia Sdn Bhd 5-2 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

Within the site itself, the hydrological regime and flow of surface run-off is basically governed by the topographic profile. Run-off from the higher areas is channelled off the site by the existing seasonal natural waterways which will eventually flow into Sg. Buloh and Sg. Damansara as shown in Figure 5.6.

5.2.4 Geological

The geological formation at the proposed Project site is predominantly underlain by acid intrusive rock according to the Geological Map of Peninsular Malaysia (1985), published by the Geological Society of Malaysia, 2008.

5.2.7.2 Land Acquisition

About 9.97 acres of land will be acquired which will include the government reserves that comprises road reserves and pipe reserves. Table 5.5 shows the tabulation of total land acquisition and total land to be surrendered.

Table 5.5: Land Acquisition Details - MBSA

5.2.7.3 Flight Path -Sultan Abdul Aziz Shah Airport

The Sultan Abdul Aziz Shah airport is an international airport located in Subang, Selangor. The Sultan Abdul Aziz Shah airport is located at the south east of the Project site, at coordinates 03° 07' 50.10" N and 101° 32' 57.60" E. The airport is 21m above mean sea level and has only one runway (“Runway 15 – 33”). The asphalt runway is 3780m long and has a width of 45m. The airport was officially opened on 30th August, 1965.

Presently, the Sultan Abdul Aziz Shah airport is only used by small aircraft, where most aircraft are of the turboprop variety, which uses propellers instead of jet engines. The airport is the main airport for Berjaya Air, Malindo and Firefly. The airport also services several private airlines that provide charter services and helicopter services. A few flight clubs also have their headquarters at the Sultan Abdul Aziz Shah airport.

The location of Sultan Abdul Aziz Shah Airport limits the type of development in the areas surrounding it. According to Annex 14 to the Convention on International Civil Aviation – Volume 1: Aerodrome Design and Operations, published by the International Civil Aviation Organization (ICAO), the obstacle limitation surfaces for Sultan Abdul Aziz Shah airport can be divided into three (3) zones, which are:

 Inner Horizontal Surface  Conical Surface  Outer Horizontal Surface

A plan view of the development area that incorporates the limitation is shown in Figure 5.15(a). A more detailed side view is shown in Figures 5.15(b).

Environment Asia Sdn Bhd 5-20 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

For the Inner Horizontal Surface, the height limit for buildings is 45m, whereas for the Outer Horizontal Surface, building height is limited to less than 145m. As for the Conical Surface, permissible building heights are from 45 – 145m. Most of the landuse within the development area lies within the obstacle limitation surfaces.

For areas that lie within the approach zone, an approach of 1.5% refers to a slope of 1.5% beginning from the end of the runway up to a distance of 15km. A 1.5% slope can be roughly translated as a ratio of 1: 66.67, which means that for every 66.67m from the end of the runway, the allowable height is 1m. Thus at a distance of 4km, the permitted height is 66m (45m + 21m above mean sea level), while at a distance of 6km, the permitted height is 146m.

5.2.7.4 Downstream Activities

Based on the site visit, no environmentally sensitive activity such as aquaculture located downstream of the proposed Project site. The nearest aquaculture activity, i.e. near Kg. Api – Api, Kg. Baru and Assam Jawa is located at a distance of 40 km while aquaculture near Pulau Babi and Pulau Tengah is about 45 km from the Project site.

The total aquaculture production is dominated by brackish/marine-water pond farming which was mainly for cockles cultivation, followed by production udang harimau or tiger prawn and freshwater pond farming which produced freshwater catfish (keli), Tilapia, puyu, perch (sepat), and snakehead (haruan).

The location of the freshwater and brackish/ marine water pond farming aquaculture activities are shown in Figure 5.16.

5.2.7.5 Future Landuse

The future landuse within 5 km will be in accordance to the Structure Plan of Selangor (2006 – 2020) and Local Plan for Shah Alam City Council 2020. According to Selangor Structure Plan 2020, the area falls under the allocation for the development of residential schemes, industrial zone, agriculture, commerce, public facilities, infrastructure and utilities (Figure 2.1). These are also in line with the State government and Federal government which have agreed to develop the RRIM land as a mixed development to support the MRT line. The development strategy of the surrounding area will be mostly steering towards the development of residential and commercial as well as towards to a complete and more developed city.

Conclusion

As the baseline noise levels recorded at the monitoring stations during day time and night time were above the DOE’s limits, noise levels during the construction phase should

adhere to Schedule 3 which stipulate the compliance limit at Leq + 3 dB(A).

5.2.10.2Existing LRT Depot (Representative for MRT Depot Sg. Buloh)

Following the meeting on 20th December 2013, the Department of Environment Selangor had requested for noise monitoring at the existing LRT Depot which will be used as a representative for noise generated during the operational phase of the MRT Depot at Sg. Buloh. The correspondence letter from DOE – (B) B 50/013/701/211 Jld. 1 (13) dated 9th January 2014 is attached in Appendix 1.

Noise levels measurement was conducted from 14th February 2014 to 16th February 2014 facing the existing LRT Depot Lembah Subang at Ara Damansara where the train maintenance works were carried out. The monitoring was conducted for 24 hours with 15 hours during day time and 9 hours during night time. The monitoring was carried out for 2 consecutive days, on a working and non-working day.

5.3 EXISTING BIOLOGICAL ECOSYSTEMS

The description of the existing biological resources within and around the vicinity of the proposed Project site is based on secondary data as well as observations from the field survey, which incorporates sightings and identification. The flora and fauna survey was carried out in November 2011.

5.3.1 Flora within Project Site

The Project site is entirely a rubber estate comprising Hevea brasiliensis with some patches of secondary vegetation and fruiting trees. The understory vegetation that was commonly observed comprises ferns and shrubs. The survey indicated that the site had high levels of ferns that include Blechnum orientale (paku Lipan), Nephrolepis biserrata (paku larat/paku pedang), Davallia denticulate, Gleichenia linearis (paku rasam) and Clidemia hirta (senduduk bulu/senduduk paksa), The types of herbaceous plants that was commonly found include Paspalum conjugatum (rumput kerbau). Another common undergrowth species observed is the small herbaceous plant Physalis minima (pokok letup-letup). Another common fruiting plant observed was the Musa paradisiaca (Banana plant). The details on the flora composition are tabulated in Table 5.18, while Figure 5.19 shows the location of the sampling plot and the vegetation distribution at the Project site.

General observation, collection and identification were made at three locations within the Project site. A quantitative assessment of the flora was made by using sampling plots of 40 m by 25 m. Observation was also made of the various plant communities found in the study area. The total biomass calculated from each plot, based on the diameter and height of the trees, provides an average estimate in the range of 115.99 tonnes and 624.43 tonnes per plot for the infra works. These survey plots of 1,000 m2 would extrapolate to an estimated biomass of about 337.699 tonnes for the Project site (refer Appendix 3).

All flora species at the Project site is commonly found elsewhere in Malaysia and their inevitable loss through site clearing does not pose any impact to the biodiversity. No rare or endemic flora species was observed at the site during the site survey. The details of the flora composition are tabulated in Table 5.18.

5.4 EXISTING SOCIO-ECONOMIC SYSTEM

5.4.1 Geographical Description of District of Petaling

Geographically, the Project site is located within Mukim Sg. Buloh, Daerah Petaling under the jurisdiction of Majlis Bandaraya Shah Alam in the State of Selangor. The Structure Plan of Selangor (2006 – 2020) reported that in 2000 the total population was 4.19 million compared to 1991 when the total population was 2.41 million. Within ten years, the increase in the Selangor population has almost doubled, with yearly average of 6.3% per year. The population is estimated to increase to 7.3 million in 2020.

The District of Petaling covers a land area of 49,865.51 hectares (6.27 % of the state). The population of Petaling district was estimated at 1,765,720 in 2010 which constitute 29.58% of the population in the State of Selangor. Of the nine districts in Selangor State, the district of Petaling has the largest population. The population profile in regards to race is as follows: Bumiputera (47.02%), other Bumiputera (1.14%), Chinese (31.96%), Indian (10.73%), others (0.74%) and non- Malaysian citizens (8.41%). The population of Petaling district is expected to grow from 1,254,846 people to 1,999,860 people from the year 2000 to 2020.

5.4.2 Social Economic Survey

5.4.2.1 Introduction

It is undeniable that when a development Project is implemented the resulting impacts will eventually affect the quality of life of the affected population, especially those who are located AROUND and WITHIN the project site which is defined as zone of influence. When assessing the quality of life, the parameters involved range from health and education to recreation and community cohesion. However, assessing social impacts is essentially qualitative in nature. The aspects to be assessed include the manner in which people go about their life from the perspectives of economics, social and cultural values. For this purpose a list of criteria has been developed as a baseline characterization in order to ensure that necessary social parameters are documented in the study such as the demographic and population effects and economic status.

5.4.2.2 Objectives

The main objectives of this Social Impact Assessment can be summarized as follow:

a. to study the existing socio-economic environment of the inhabitants living within the Project’s zone of influence defined as areas within 3 km radius from the Project site;

b. to make the assessments of the impacts on the inhabitants and socio-economic environment as a result of the construction of the proposed Project and;

c. to suggest the mitigating measures that could be adopted to minimize the negative impacts during and after the completion of the proposed Project on the affected population whilst providing the most socio-economic benefits to the society at large.

Environment Asia Sdn Bhd 5-41 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

The assessment of the impacts of the proposed Project will be made based on the consultant’s site visit and on the primary data, collected via the socio-economic survey conducted to the inhabitants of the identified area of study. The primary data pertaining to the respondents’ personal profile and their perceptions towards the proposed Project were collected using the sample survey technique.

5.4.2.3 Survey Research Methodology

The primary data were collected directly from the inhabitants residing within the zone of influence. The fieldwork for the survey was conducted in the month of November 2011 by the SIA team members led by Dr. Mohd. Alias Lazim. The field survey work using face- to-face interview method was conducted using a specially constructed questionnaire to be filled-up by the enumerators during the interview period, normally chosen at the place of residence of the respondents.

A simple study was conducted on the local community. As such, the sampling procedure employed was the selection of samples from nine main locations; Section 8 Kota Damansara (85 m from site), Subang Impian (290 m from site), Kg. Baru Subang Orkid (370 m from site), Kg. Baru Sg. Buloh (813 m from site), Section 6 Kota Damansara (900 m from site), Section 4 Kota Damansara (1000 m from site), Taman Subang Perdana (1014 m from site), and Kg. Paya Jaras Hulu (1200 m from site). The number of respondents required for each category of the respondents was made known to the enumerators and they were required to ensure that these were adhered to. The sample size selected constituted 72 respondents. Figure 5.20 shows the location of the socio survey carried out.

5.4.2.4 Profile of the Overall Respondents

5.4.2.4.1 Gender of Respondents

Of the total of 72 respondents interviewed, 33 or 45.8% were male and 39 or 54.2% were female. 50 (69.4%) were married while 22 (30.6%) were still single.

5.4.2.4.2 Age Distribution

Overall, the age of the respondents is evenly distributed from 21 years to the oldest at 76 years old, with a mean of 41 years (Table 5.22). This distribution reflects well on the information gathered which indicates that the age groups most probably belong to the highly economically active population.

5.5.3 Telecommunications

Telecommunication services (both phone and internet) for Selangor State are provided by a few telecommunication service providers such as Telekom Malaysia Berhad (TMB), Celcom and Maxis. The estimated amount of fixed lines provided for the state was 1,145,105. The estimation of the growth demand is 3.5% per year. For the mobile phone, the total estimation for the mobile phone users is 8 million. The estimation of the growth demand for the mobile phone is 30% per year.

For the internet services, there is an estimation about 1.2 million registered users. The growth of the internet services demand is over 60% per year.

5.5.4 Sewerage System

Indah Water Konsortium (IWK) is mainly responsible for operating and maintaining the public sewage treatment plants and network of underground sewerage pipelines in the

Environment Asia Sdn Bhd 5-47 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

State of Selangor. IWK has been given the concession to manage the domestic sewage system since 1993. Most of the residential area around the development site uses public sewage treatment plant, which is under the operation and maintenance of Indah Water Konsortium.

5.5.5 Road System

The viability of the proposed development is enhanced by its accessibility via New Klang Valley Expressway (NKVE), Guthrie, North- South Expressway and Jalan Sg. Buloh.

5.5.6 Solid Waste Management

General and domestic waste will be disposed in rubbish bins and these will be emptied and removed by a licensed contractor to a municipal dumpsite approved by the Local Authority of Majlis Bandaraya Shah Alam (MBSA).

Majlis Bandaraya Shah Alam is responsible for the collection of solid waste within the District of Petaling. Presently, the sanitary landfill area for solid waste disposal is located at Ayer Hitam (Majlis Bandaraya Shah Alam, 2014).

5.6 NEARBY SENSITIVE RECEPTORS / AREAS

The location of the proposed Project in relation to the environmentally sensitive areas is shown in Figure 5.21, extracted from the Structure Plan of Selangor. The Structure Plan categorizes the sensitive areas based on characteristics such as steepness of area, wildlife habitats and presence of forests. Based on these factors, it is observed that the proposed Project is not located within any environmentally sensitive areas that are either critical or located within any wildlife habitats and areas prone to floods, except that there are few quarry sites nearby the site. Sg. Buloh Forest Reserve is located within 1 km to the east of the proposed Project site. FRIM Kepong and Bukit Cerakah Forest are located within 4 km to 5 km to the northeast and southwest, respectively.

Other potentially sensitive receptors in the form of high density residential areas near to the site are shown in Figure 5.13 and Figure 5.14.

With regards to the water quality, the northern development site (under MBSA) is only drained by Sg. Kedondong and Sg. Payong. Sg. Payong is a seasonal natural waterway which is dry during the dry seasons. Sg. Kedondong will flow into Sg. Buloh and subsequently into the Straits of Malacca while Sg. Payong will flow into Sg. Damansara (southern development) and subsequently into Sg. Kelang and eventually into the Straits of Malacca.

There are no water intake points located downstream of the Project site within the Sg. Buloh catchment area and Sg. Kelang catchment area.

6.2 PRE-CONSTRUCTION PHASE

Preliminary investigation works are not expected to cause any significant impacts. The main activities during these preliminary works were survey of flora and fauna and the monitoring of water, air, noise and vibration levels. The site surveying works, which were carried out, include site investigations to acquire appropriate information for engineering design and topographic surveys. No significant adverse impacts are expected during this stage as disturbance to flora and fauna is minimal and negligible.

6.3 CONSTRUCTION PHASE

This PEIA submission will only cover the earthworks for master infrastructure facilities (hereafter referred to as construction phase) which will be limited to:

a. Major arterial and collector road networks i.e. all road networks. b. All primary infrastructure utility land areas i.e. water tanks, DCS (District Cooling System), to prepare the ground for the construction of these utility structures. c. All main drains, waterways and detention / retention facilities d. River works as required by JPS. e. Some parcel developments for the purpose of borrow pits.

The construction phase of the proposed Project will involve mobilization of labour, equipment and materials to the Project site, cutting and clearing of the rubber trees and vegetation.

The construction of the individual phases of the development will be undertaken by other sub-developers and is not covered under this present EIA scope. A Supplementary Environmental Impact Assessment Report (SEIA) will be submitted by the respective sub- developers before the construction phase of the individual phases.

6.3.1 Soil Erosion and Sedimentation

Land clearing and earthworks for the infrastructure works will inevitably involve land disturbance whereby the soil surface will be exposed to physical elements such as wind and rain. Heavy rain and strong winds will erode the bare ground surfaces which may subsequently lead to increase sedimentation of the nearby waterway if appropriate mitigation measures are not taken.

As the present construction works at the site is to develop the required platform level for infrastructures for the development first, there is minimal land clearing and exposures of open ground to erosive rain forces. The individual phases of the development shall not be cleared and will be left in their original condition. Once the phase is purchased or acquired, only then will that phase be cleared out. As such, soil erosion is not expected to be a significant impact during the construction phase of the proposed Project.

Environment Asia Sdn Bhd 6-3 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

6.3.1.1 Estimation of Soil Erosion

The objective of soil erosion and sediment calculation is to estimate the amount of silt runoff and the rate of erosion occurring on disturbed areas. This calculation will provide a guideline for the implementation of the Best Management Plans (BMPs). The soil erosion and sediment yield analysis were carried out to estimate the total amount of soil loss and sediment yield for the proposed development. The calculation of the total soil losses was determined using the Revised Universal Soil Equation (RUSLE) while the sediment yield calculation was determined based on the Modified Universal Soil Loss Equation (MUSLE) formula.

The calculation of soil loss and sediment yield was prepared based on the “Guidelines Document for Addressing Soil Erosion and Sediment Control Aspects in Environmental Impact Assessment (EIA) Report”, by the Department of Environment, 2010 and “Guideline for Erosion and Sediment Control in Malaysia” by DID, 2010.

6.3.1.2 Revised Universal Soil Loss Equation (RUSLE)

The prediction of soil erosion and sediment delivery has continued to be refined to reflect the importance of different factors on soil erosion and runoff. The United States Department of Agriculture Natural Resource Conservation Service generated the Revised Universal Soil Loss Equation (RUSLE) based on the original USLE which was a widely used method for quantifying soil erosion and developed for cropland and later extended to other land uses by Wischmeier and Smith (1978).

The RUSLE is an erosion model that combines index and process-based equations to estimate erosion rates and is designed to predict the longtime average annual soil loss carried out by runoff from specific slopes in specified management conditions. The RUSLE brings in a mixture of empirical and process-based erosion technology to provide a better measure of the effect land management on erosion rates.

Compared to the previous Universal Soil Loss Equation (USLE), three of the five parameters have been updated. The updated parameters are rainfall factor (R), soil erodibility factor (K) and topographic factor (LS). The RUSLE formula to calculate soil erosion is shown below and the rate of erosion is dependent on these variables:

A = R . K . LS . C . P

Where, A = Average annual soil erosion loss (t/ha/yr) R = Rainfall erosivity factor (MJ.mm/(ha.hr.yr)) or Nm-2mm.hr.-1 K = Soil erodibility factor (t.ha.hr/ha.MJ.mm)), defined as the mean annual soil loss per unit erosivity for a unit plot LS = Slope factor, which is the combination of the slope length (L) and slope steepness (S) C = Cover management factor, representing the ration of soil loss under a given crop to that from bare soil. For bare soil, C = 1.0 P = Conservation practice factor, representing the ratio of soil loss where conservation is practiced to no conservation measure taken. For no conservation measures, P = 1.0

Environment Asia Sdn Bhd 6-4 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

Based on the Department of Agriculture Land Erosion Risk Map, the erosion risk categories are as follows:

EROSION RISK (t/ha/yr) RISK CATEGORIES <10 Low 10-50 Average 50-100 Above average 100-150 High >150 Very high

Soil erosion during construction phase may result in the discharge of suspended sediment into the existing waterways and lead to the deterioration of the water quality of the nearby river.

6.3.1.3 Modified Universal Soil Loss Equation (MUSLE)

The Modified Universal Soil Loss Equation (MUSLE) (Williams, 1975) calculates the sediment yield in a watershed to a specific location for a specific storm event. This allows for volume determinations for basins based on design storms rather than area volume ratios. The MUSLE has the form shown as below:

0.56 T = ψ2 (V . Qp) . K . LS . C . P

Where, T = Sediment yield per storm event (tones or tons)

ψ2 = 89.6 for SI units V = Volume of runoff (m3 or acre-feet) 3 3 Qp = Peak flow (m /s or ft /s)

K, LS, C and P are RUSLE Parameters

6.3.1.4 Quantification of RUSLE

Soil erosion and generation of sediment are identified as one of the impacts resulting from land clearing and earthworks for infrastructure works. The extent and magnitude of the soil erosion is governed by a number of factors such as slope steepness, slope length, rainfall intensity, soil erodibility, land cover and soil conservation practice.

Rainfall Factor (R)

The rainfall factor (R), is derived from probability statistic by analyzing additional rainfall records of individual storm and the data is obtained from rainfall station nearest to the Project site based on average ten years records. The rainfall erosivity index has been modified by FRIM (1999) for Malaysian conditions. It is expressed in units of cumulative value of storm rainfall erosivity index (EI), for a fixed period of time. The following relationships between R, EI and annual rainfall are given in FRIM (1999):

R = (E . I30) / 170.2 E = 9.28 P – 8838.15

Environment Asia Sdn Bhd 6-5 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

Where,

I30 = the maximum 30-minute rainfall intensity (mm/hr) with design 10 year ARI E = annual erosivity (units of J/m2) P = annual rainfall (mm)

For soil loss computations, R value was employed based on a uniform annual rainfall over the Project site. The annual rainfall of 2,114.16 mm was based on the Annual Rainfall Data for Peninsular Malaysia published by the Department of Irrigation and Drainage, Malaysia as tabulated in Appendix 4.

Soil Erodibility Factor (K)

The factor K is a function of several soil properties such as percentage of silt and fine sand, percentage of sand, organic matter content, soil structure and permeability. The K value for the existing and construction phase of the Project was calculated to be 0.044 using the nomograph method whereby the percentages of sand, silt and clay was obtained from soil structure categories for 26 Malaysian Soil Series. During the operational phase, an estimated value of 0.02 will be used as there will be paved road networks, concrete lined box drains and detention ponds.

Slope Factor (LS)

The factor is based on the average slope length and slope steepness of each critical area for slope length (L) and slope steepness (S) in meter and percent respectively. The LS value was derived using the reference table of Slope Length and Steepness Factor (LS). Using this table, a range of Slope Length (LS) could be estimated through extrapolation, given the Slope Steepness (%).

Land Use Management Factor (CP)

The Land Use Management Factor (CP) is derived from the Crop Management Factor (C) and the Conservation Practice Factor (P). Therefore, the type of vegetation growth over the land area determines the C value while the conservation factor (P) is the value given to protective measures. The Land Use Management Factor (CP) for the existing condition is 0.25 as the Project site is located within a rubber estate. The CP value for the construction stage for worst case scenario is 1.0 assuming all vegetation will be cleared and no conservation practices will be introduced. The CP value for the case scenario with implementation of mitigation measures during construction phase is based on the Best Management Practices, in which the C value for mulching practices and cover is 0.25 while C value of 1.00 is for bare soil. The P value for sediment basin and temporary earth drains is 0.50. The CP value for the operational phase is 0.005 after the development of the required infrastructures.

Curve Number (CN) and Surface Runoff (V)

The Curve Number method is the most widely used method to compute runoff from rainfall. The effects of soil type, land use/treatment, surface condition and antecedent

Environment Asia Sdn Bhd 6-6 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

condition are considered using this method of predicting the volume of runoff generated from a storm event.

The CN values for various cover types on different hydrological soil groups in Malaysia have been provided in two CN values factor table – one for forested and undisturbed lands, and for agricultural and urbanized areas. The SCS Rainfall – Runoff Chart, consists of specific curve numbers where runoff from rainfall can be determined from this method. Then, the volume, V, can be calculated by multiplying the runoff depth with the areas involved.

The CN value can be determined using the following equation.

CNc = CN1(A1/Atotal) + CN2(A2/Atotal) + …… CNn(An/Atotal)

Peak Discharge (QP)

A few methods can be used to determine the peak discharge, Qp. Examples are the Rational Method (DID, 2000), Time Area Method (DID, 2000), TR-55 Graphic Method (SCS, 1986), SCS Triangular Unit Hydrograph (SCS, 1972), etc. In Malaysia however, the Rational Method (for small catchment only), and Time Area Method are the recommended methods in MSMA (DID, 2011).

6.3.1.5 Soil Erosion Analysis

The soil erosion analyses were carried out for pre-construction, during construction and post construction. Analyses during construction were considered on two case scenarios: i.e. based on the worst case scenario whereby the infrastructure works were assumed to be cleared simultaneously and no conservation practice will be introduced. The second scenario was assumed with implementation of mitigation measures during the construction phase. The rates of soil erosion are shown in Table 6.2 while the detailed calculation of the soil erosion is shown in Appendix 4.

Table 6.2: Estimated Soil Erosion Rates for the Project Development

STATE OF DEVELOPMENT AVERAGE RATE OF SOIL EROSION (t/ha/yr) Pre-Construction 34.50 Construction Phase - Worst Case Scenario 110.410 - With Mitigation Measures 23.086 Post Construction 0.281

The estimated total rate of soil loss for the proposed Project site under the existing condition is 34.5 tons / ha / yr.

The average rate of soil loss during the construction phase, with the assumption of no conservation practices (bare land) and no phasing of the Project is estimated to be 110.410 tons / ha / yr. The average rate of soil loss with the assumption of implementation of mitigation measures is estimated to be 23.086 tons / ha / yr.

Environment Asia Sdn Bhd 6-7 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

Based on the Department of Agriculture’s Land Erosion Risk Map, a rate of soil erosion at 50-100 t/ha/yr is classified as above average erosion risk, while an erosion rate of 100- 150 t/ha/yr is classified as high erosion risk.

Therefore, the erosion risk of the infrastructure works during the construction phase would be considered as average risk. However, the actual sediment yield will be considerably lower if mitigation measures are implemented.

After the completion of the construction phase, soil erosion and its effects will be reduced considerably as the exposed areas would be fully turfed / paved / tarred as hard-standing surfaces with no possibility of surface erosion. The average rate of soil erosion during the operational phase was estimated at 0.281 t/ha/yr. Figure 6.1 (a) – Figure 6.1 (d) shows the soil erosion rate of the Project site during existing, construction phase (worst case scenario), construction phase (with mitigation measure) and during operational phase.

6.3.1.6 Sediment Yield and Discharge analysis

Similar with the calculation of total soil loss, the sediment yield and discharge analysis were carried out for pre-construction, during construction and post construction. The sediment yield is shown in Table 6.3 while the MUSLE Detailed calculation attached in Appendix 4.

Table 6.3: Estimation of Sediment Yield and Discharge from the Project Site

6.3.2 Slope and Terrain Analysis

Based on the slope gradient analysis, the proposed northern development is predominantly categorized as slopes of Class I. The construction activities would only require the land to be leveled for the infrastructure work and the individual phases will be left in their original condition. Hence, no serious slope stability problems are anticipated.

6.3.3 Drainage and Flooding

The potential impact on the hydrological regime is a change in runoff within the catchment area. This arises from the increased proportion of less permeable area and shorter retention as a result of landuse conversion.

During the construction period, temporary drains and temporary culverts will be constructed to accommodate this change in surface run-off. Generally, the temporary drainage system will consist of temporary earth / perimeter drains that will eventually lead to the sediment basin before being discharged into the existing drainage system and subsequently to the nearest waterways. The sizing of the sediment basin must be able to accommodate the change in run-off during the construction phase. There is little potential for flooding unless clearing, cutting and filling operations for the infrastructure works are carried out in unscrupulous manner that causes the temporary drains and eventually downstream of the water channel to be clogged up by biomass or solid/construction wastes.

6.3.4 Water Pollution

Any potential impact to nearby water quality will involve the existing rivers and the surrounding drainage systems. Any land clearing activities and earthworks activities for the infrastructure works of the internal access road and the ancillary facilities will expose the soil surface to physical elements such as wind and rain. During and after rains, the surface run off will transport the loose soils into the surrounding drainage systems and receiving water bodies (Sg. Kedondong, Sg. Paku and Sg. Payong) resulting in siltation. As a result, the capacity of the existing drainage system can be reduced and could increase the risk of flash floods in low-lying areas.

Besides silt, there is also the potential of construction waste materials and pollutants entering the drainage system and subsequently the nearby rivers. The improper storage and indiscriminate disposal of wastes can lead to blockages of the drainage system, thus creating breeding grounds for disease vectors and decreasing the aesthetic view of the area.

The potential impacts to the water quality during the construction phase include:

 Sediment runoff during construction phase may increase the TSS and turbidity levels of the receiving waterways.  Spillage and/or leakage of fuel, oils and lubricants, either through improper storage or improper maintenance of machinery/equipment can cause oil or grease contamination of the receiving waterways.

Environment Asia Sdn Bhd 6-13 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

 The improper discharge or spillage of construction materials (i.e., sand, cement slurry, etc.) into the drainage system via surface runoff, will deteriorate the water quality.  Indiscriminate disposal of solid wastes, construction debris and spoil into the temporary drainage system will affect the flow and capacity of the drainage system.

6.3.5 Air Pollution

Fugitive dust emission and dispersion from the general infrastructure activity at the site represent a potential impact on the air quality. Fugitive dust generation will potentially be higher during the earlier stages of the Project when there is site clearing and continuous movement of construction vehicles into and out of the site for infrastructure works. In addition, emissions from the construction vehicles and machinery could contribute to

ambient air quality degradation due to the increase of NOx, SOx and CO levels. However, the exhaust fumes will be readily dispersed in the atmosphere due to the `open’ condition of the Project site.

The primary concern of air pollution is the impacts on aesthetics, safety, personal discomfort and health. These undesirable effects are summarized in Table 6.4.

Table 6.4: Detrimental Effects of Air Pollutants

EFFECT DESCRIPTION Aesthetics Loss of clarity with high dust fallout. Economic Losses Damage to vegetation, crops and livestock. Corrosion of metals, darkening of lead-based white paint, cracking of rubber and deterioration of fabrics. Safety Hazards Decreased visibility affecting ground and air transportation. Health Hazards Eye irritation and respiratory difficulties. Source: Canter, 1977.

The extent of air pollution impact on the sensitive receptors is dependent on the localized prevailing wind directions as well as the location where the infrastructures works are being carried out. The closest sensitive receptors is the residential area of Section 8 Kota Damansara which is about 85 m from the Project site boundary, may experience a certain degree of air pollution when the infrastructure works begin at the north eastern portion of the Project site. The wind rose data from the Subang Airport Station indicates the prevailing wind directions are from the northwest, north, south and west directions which may cause dust dispersion towards residential areas in Taman Perindustrian Sg. Buloh (southeast), Seksyen 7 Kota Damansara (west) and Kg. Baru Sg. Buloh (north). No disposal or import of excess material will be required as there will be no excess cut or fill material. Overall, the adverse impact is expected to be localized, temporary and restricted during the permitted working hours during the construction phase.

6.3.6 Noise Pollution

6.3.6.1 Noise Source

During the construction phase, the bulk of the noise is expected from dozer, tracked excavator, wheeled backhoe loader and paver. These will produce noise during their operations. Their noise levels will be predicted to assess their disturbance onto the sensitive receptor.

6.3.6.2 Methodology

In the assessment of noise, a common statistical descriptor is LAeq. LAeq is the constant, average noise level, which over a period of time, contains the same amount of energy as the varying levels of the background or traffic noise. The total equivalent sound level for a typical workday during a particular construction phase can be computed as follows:

(LAeq i / 10) LAeq = 10 x log10 ∑ [10 ] (dB)

Where, LAeq, total = the total equivalent noise level for a typical workday during a given period k = the number of different types of equipment

LAeq, i = the equivalent noise level for equipment type, i.

Giving the total equivalent sound level from a construction site or point source, noise at specific distances from a point source is calculated using the formula for distance attenuation:

L = L0 - 20 Log D

Where, L = noise level at D meters away from the source

L0 = noise level measured at 1 m from the source D = distance from the point source in m

6.3.6.3 Assessment Results

Table 6.5 presents typical noise levels from equipments likely to be used at the construction site.

The nearest sensitive receptors to the proposed Project site have been identified as a residential and baseline noise monitoring at this location was conducted in conjunction with the EIA study. With the baseline result as background noise, the combined cumulative noise level due to the construction noise and background noise is computed. Table 6.6 shows the result of the estimated noise levels at the sensitive receptors which is also shown in Figure 6.2 while Table 6.7 shows the result of the cumulative noise level at the sensitive receptor.

The estimated noise level at the sensitive receptor is only marginally higher compared to the existing background noise. Furthermore, it should be noted that the result is based on the worst-case scenario, assuming the high-noise generating equipment are in operation

Environment Asia Sdn Bhd 6-16 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

simultaneously and the area affected is completely bare and void, without barriers or vegetation to effect any form of noise reduction or attenuation. The computed result is highly influenced by the number of equipments generating high noise levels at any one time and the equipments with the highest noise level.

The major cut and fill will be carried out at the western portion and the middle portion of the site. The nearest sensitive receptor to the Project site boundary is residential area of Section 8 Kota Damansara (85 m). Nevertheless, noise from the operation of vehicles /equipments would be intermittent, localized, short-termed and restricted to the working hours. Mitigating measures are proposed where necessary during the construction phase. In addition, the noise level during the construction phase will be closely monitored.

6.3.7 Vibration

The potential for vibration impact at the adjacent sensitive locations around the Project site during the construction phase is minimal and mainly only from vehicular movements. However, the actual vibration impact is not significant as the major activities at the Project area will involve infrastructure works and no piling activities are required.

6.3.8 Ecology

6.3.8.1 Flora

Under the development concept, the existing vegetation within the Project site will not be totally removed in a single operation. Site clearing will only be carried out at the areas where infrastructure work will be carried out. Any biomass removed from the site will be stockpiled at the designated areas for composting.

The flora of the proposed site consists of rubber trees and its associated understorey of ferns and herbaceous plants and epiphytes. No endangered or endemic species are found.

From the viewpoint of conservation, the destruction of flora at the development site is not a cause of concern as the vegetation is primarily either agricultural or secondary in nature and many of the species were introduced. The removal of this vegetation will not jeopardize the biodiversity of plant species in the area or region.

6.3.8.2 Fauna

During site clearing, the more mobile fauna at the proposed site will migrate to the adjacent areas although the less mobile ones will probably perish. Generally, the impact on the fauna diversity is expected to be negligible as no endemic species were found in the area.

6.3.9 Socio-Economic Impacts

6.3.9.1 Traffic

Traffic arising from infrastructure activities mainly involves the transport of workers, and materials for road works in and out of the Project site.

Based on the traffic study carried out by Perunding Trafik Klasik Sdn Bhd, most of the road network surrounding the proposed site is currently operating at Level of Service (LOS) of A, B, C and D during the daytime and LOS of B,C and E during night time. Table 6.8 shows the existing traffic volume on the main road during peak hours. Figure 6.3 and Figure 6.4 indicate the volume/capacity ratio and level of service for morning and evening peak periods respectively.

Based on Table 6.8, the road network surrounding the proposed site is currently operating at between Level of Service B to C. However, the worst level of service in this area is only

Environment Asia Sdn Bhd 6-18 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

on Jalan Lapangan Terbang Subang (Subang Airport to Jalan Sg. Buloh direction) which operates at Level of Service E during evening peak hour.

Jalan Sg. Buloh leading to the Project site will most probably be used by heavy trucks and vehicles carrying construction materials for road works and workers to the construction site, as shown in Figure 6.5. The volume of heavy vehicle traffic entering/leaving the construction site are expected to increase but will vary throughout the construction period, dependent upon the on-going construction activities. Therefore, it is important that proper road signs and traffic control be provided near and at the construction access road to warn motorists of the movement of construction vehicles in the area. Without any traffic control measures, there is the possibility that the presence of heavy vehicles plying the main access road can hinder or endanger other road users in the vicinity of the Project site.

The other construction traffic is worker vehicular traffic and is normally associated with light vehicles such as motorcycles, cars and vans. Generally, the size of workforce would vary at any one time depending upon the infrastructure activities and implementation schedules. Most construction workers may stay in camps within or near the construction site and thus do not contribute to the generation of traffic during the construction stage. However, skilled workers and a small proportion of general workers as well as staff of the developer would commute daily to and from the construction site. The minor increase in traffic is not expected to cause any congestion to the existing traffic condition.

6.3.9.2 Aesthetics

Land preparation for site clearing for the infrastructure works will cause minor aesthetic alteration to the existing landscape. In view that site clearing and earthworks will be carried out for the infrastructure works, a large portion of the site will be left in their original condition. The minor impact on aesthetics is expected from the presence of heavy vehicles, machinery and debris during the construction period.

6.3.9.3 Estate Workers

The welfare of the estate workers remains under the purview of RRIM. The estate workers were relocated to other estates in early 2014.

6.3.9.4 Health and Safety Concerns

Public Health and Safety On the whole, the Project is not likely to cause any detrimental health effects to the public. Any potential minor impact on public health and safety is likely to occur during the construction phase of the proposed Project being mainly due to the presence of heavy vehicles/machineries (dozer, tracked excavator, wheeled backhoe loader and paver). The noise arising from this can be a source of irritation and discomfort to those living close to the Project site. These will produce noise during their operation. Improper housekeeping and waste management at work areas could provide breeding grounds for mosquitoes, flies and rats that may cause adverse health impacts to local residents. Besides, the movement of heavy vehicles entering and exiting the site could be a hazard to the safety of residents in the local vicinity if no proper traffic management plan is implemented.

Environment Asia Sdn Bhd 6-19 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

Occupational Health and Safety Potential occupational hazards at construction sites pose a threat to the health and safety of construction workers. Continuous exposure to hazards such as noise and dust emissions is likely to cause adverse health effects to workers. In addition, improper management of sanitary facilities such as sewage and solid waste may affect the general health of workers. In relation to health, the threat of water and food-borne diseases such as food poisoning, diarrhea diseases, typhoid and dysentery as a result of unhygienic living condition, must also be considered. There is also a high possibility of disease occurrence such as tuberculosis and malaria.

6.3.9.5 Employment Opportunities

An immediate potential benefit of the proposed Project to the local population is the generation of employment and business opportunities. During the construction phase significant number of jobs is expected to be generated at the Project site and hence the effect of the spin-off should be able to help uplift the socio-economic status and income levels of the local communities, in particular for those at the lower end of the income scale.

Raw materials, machinery and equipment required for the infrastructure works of the proposed Project will create business opportunities for the local suppliers and contractors.

There will be some business opportunities for the locals to meet the demand of the workers at the work site. The construction phase will require manual workers, skilled workers and professionals. The majority will be manual unskilled labour required for the site preparation and construction-related activities. The work force can be supplied from the local population. However, foreign workers will also be recruited if there are not enough local workers.

The increase in demand for infrastructures and services to accommodate them may give rise to social problems. Negative and wrong perceptions may lead to their presence being a source of discontent to the local population as a result of differences in their pattern of social interaction, behavior, customs and traditions.

There is the possibility that cultural and language differences among the local population and foreign workers may lead to social issues. In addition, foreign and local workers are expected to arrive at the Project site in search of jobs and employment. Although not always the case, surrounding residents may perceive this as the cause of the increase in the incidence of thefts or petty crimes around the residential area.

6.3.10 Biomass, Solid Waste and Scheduled Waste

The total amount of biomass expected from the site clearing is about 337.7 tonnes. The estimated biomass to be disposed is tabulated in Appendix 3.

The main types of solid waste expected from the Project site comprise mainly domestic waste (food wastes, rubbish and general discards), spoil generated during earthworks and construction debris. These wastes can pollute the water quality of the receiving waterways

Environment Asia Sdn Bhd 6-20 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

if there are improper disposal of these wastes. The indiscriminate disposal of solid waste can result in a health hazard to local residents.

In addition, there will also be scheduled wastes such as waste oil and lubricants during the infrastructure works. All scheduled wastes have to be stored, removed and disposed according to the Scheduled Waste Regulations 2005.

6.4 PROJECT ABANDONMENT

In the unlikely event that the proposed Project, at any stage, cannot proceed and has to be abandoned due to unforeseen circumstances, the likely impacts arising will depend on the state of progress that had been achieved prior to work stoppage.

If Project abandonment occurs at any stage during the construction work, there is a potential fiscal loss as the cost of the construction works is irrecoverable and any equipment already mobilized into the site or installed will have to be dismantled and additional transportation costs incurred for removal.

6.5 OPERATIONAL PHASE

6.5.1 Drainage and Flooding

Surface runoff within the Project site is expected to increase resulting from the reduction in rainfall infiltration capacity of the soil due to the presence of road networks and main drains. The increase in runoff will be due to the change from vegetated land and open ground areas to impermeable surfaces as found in the constructed development. Hence, surface runoff detention is important to accommodate the increased flow and channeling it to the proper outlet.

The increased surface runoff within the Project area will be channeled into the detention ponds before discharging into the main drain reserve. In order to attenuate the increased stormwater runoff from the Project area under MBSA, 4 detention ponds are proposed to control the outflow to downstream waterway. Besides flood control, the detention ponds will have proper river bank protection and landscape design which may serve as recreational purpose.

6.5.2 Water Pollution

Soil erosion and sedimentation problem is insignificant upon full operational due to the paved surface and vegetated land. Although, the sewage treatment plant (STP) will be located at the southern portion of the development which is under Majlis Bandaraya Petaling Jaya, contamination of sewage into the receiving waterways may occur due to pipe leakage in the sewerage system (Figure 3.3). Apart from that, effluent that does not comply with the required Standard B of the Environmental Quality (Industrial Effluent) Regulations, 2009 may be discharged due to any malfunction of the sewage treatment plant (STP).

6.5.3 Air Pollution

The proposed Project has no hazardous air emissions during the operational stage. Any potential source of air pollutants will be from vehicles entering and exiting the area. The primary emissions of air pollutants from automobiles are carbon monoxide (CO), nitrogen oxides (NOx) and organic compounds. Among these pollutants, CO is of most concern as it is toxic in high concentrations. As such, air quality modeling was carried out to determine the emission of CO from the increase in traffic activities due to the proposed Project.

CALINE4 is an air dispersion model developed by the California Department of Transportation (CALTRANS) used to predict concentrations of CO near roadways. Its predecessor, CALINE3, is one of the air dispersion models recommended by the US Environmental Protection Agency. CALINE4 is a simple line source Gaussian plume dispersion model capable of determining 1-hour and 8-hour average CO concentrations at receptor locations downwind of highways located in relatively uncomplicated terrain. CALINE 4 requires the following input data:

 Roadway geometry  Worst-case meteorological parameters

Environment Asia Sdn Bhd 6-26 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

 Traffic volumes  Vehicular emission rates  Receptor positions

The CALINE4 model was applied to the entire northern Project site, calculating the 1-hour average CO concentrations. The roughness coefficient was assumed to be 400 cm, which corresponds to a landscape characteristic of a business central district, a general assumption as how the Project area will be when completed. The altitude above mean sea level was assumed to be 43 m, according to the average platform levels. The highest peak hour traffic generated by the proposed Project is expected to be 15,511 vehicles per hour during morning peak hour and 14,152 vehicles per hour during night time based on the traffic assessment report by Perunding Trafik Klasik Sdn Bhd.

Vehicular emission rates were based on the current legislation governing the emissions from petrol and diesel engines, which is the Environmental Quality (Control of Emission from Petrol & Diesel Engines), Regulations, 1996. The maximum allowable emission limit for CO is currently set at 6.90 g/km for heavy vehicles.

The 1-hour average concentrations for CO were simulated based on the projected traffic volumes using the worst-case wind speeds and wind angles. The predicted concentrations include an assumed ambient concentration for CO, which was 0.722 ppm in 2012 (EQR, 2012). The modeling was performed using the two extremes of the atmospheric stability classes; the most stable (Class 7) and the most turbulent (Class 1).

The receptor position was based on the location for the potentially sensitive receptor of Section 8 Kota Damansara, Section 7 Kota Damansara and SJK (T) RRI Sg. Buloh in relation to Jalan Sg. Buloh. Appendix 5 shows the output results of the air quality modeling. A summary is shown in Table 6.9.

Table 6.9: Predicted 1-Hour CO Concentrations upon Completion of Project

TRAFFIC EMISSION 1-HOUR AVERAGE CO AMBIENT CO VOLUME RATES CONCENTRATIONS LOCATION CONCENTRATIONS (VEHICLES FOR CO (PPM) (PPM) PER HOUR) (g/km) CLASS 1 CLASS 7 Section 8 Kota 4572 6.90 0.722 2.8 4.3 Damansara Section 7 Kota 4572 6.90 0.722 1.3 2.2 Damansara SJK(T) RRI Sg. 4572 6.90 0.722 0.8 1.2 Buloh

The highest predicted 1-hour average concentration is 4.3 ppm, which is still lower than the Malaysian Ambient Air Guidelines of 30 ppm. Hence, no significant impacts to air quality are expected due to emissions from the increase traffic upon completion of the Project.

6.5.4 Noise Pollution

6.5.4.1 Road Traffic

Based on the baseline monitoring results, one monitoring station (N2) had noise levels exceeding the recommended guidelines during day time and night time, while station N1 had exceeded the limit during night time only.

The potential sources of noise pollution during the operational phase will mainly be from the increase in vehicle traffic. The volume of traffic generated by the proposed Project is estimated using Trip Generation Manual, 2003. The noise level generated by traffic from the main access road (Jalan Sg. Buloh) was used to determine the noise impact on the nearest residential receptor, Section 8 Kota Damansara, Section 7 Kota Damansara and SJK(T) RRI Sg. Buloh.

Based on the predicted traffic volume, noise modeling was carried out using the empirical equation developed by the Ontario Ministry of Transportation of Communications (Davis & Cornwell, 1998) as shown below:

Leq = 42.3 + 10.2 log10 (Vc + Vt) - 13.9 log10 D + 0.13S Where,

Leq = energy equivalent sound level during one hour (dB)

Vc = volume of automobiles (four tyres only) (veh/hr)

Vt = volume of trucks (six or more tyres) (veh/hr) D = distance from edge of pavement to receiver (m) S = average speed of traffic flow expected at during one hour (km/hr)

Assumption (i) Percentage of light vehicles is assumed at 100% light vehicles (ii) The average speed of all vehicles is assumed to be 60 km/hr

The predicted cumulative noise level of the noise generated by the increase in traffic and the existing noise level is determined based on Table 6.10. The noise levels during the peak hour will be used to determine the highest noise level for both daytime and nighttime.

From the noise modeling, the predicted noise level generated from the Project’s road at the various distances to the sensitive receptor is shown in Table 6.11.

the Existing Noise Climate, LAeq (existing level)+ 3 dBA), of the Planning Guidelines for Environmental Noise limits and Control, 2007.

From the results, the predicted noise level generated from the road traffic would cause the cumulative noise level at Section 8 Kota Damansara (N2) to increase to 64.4 dB(A) for daytime and nighttime levels to increase to 61.3 dB(A). At Section 7 Kota Damansara, the cumulative noise level would be 63.8 dB (A) for daytime and a nighttime level of 60.4 dB (A). At SJK (T) RRI Sg. Buloh, the cumulative noise level would be 55.8 dB (A) for daytime and a nighttime level of 53.8 dB (A). The cumulative noise level would still comply with the compliance limit for both daytime and nighttime. Thus, noise generated by the increased traffic activities for the proposed northern Project site during operational would not be significant.

6.5.4.2 MRT Depot – Sg. Buloh

The MRT Depot at Sg. Buloh will comprise of two main zones, namely:

 Fully Automatic Operation (FAO) Zone – covers stabling track, arrival track, departure tracks and transition zones. Train movements within the FAO Zone will be managed by Operation Control Centre (OCC).

 Manual Zone – covers other depot tracks including the light maintenance tracks, lifting tracks, heavy repair tracks, train stabling tracks, locomotive shed and permanent way sidings. Train movements within the Manual Zone will be under the control of deport controller.

The facilities that will be provided in the MRT Depot include:

a. Stabling tracks b. Light maintenance pits with fixed roof access platforms and overhead cranes c. Lifting tracks with screw jacks an overhead cranes d. Heavy repair tracks e. Rolling stock workshop f. Heavy cleaning platforms g. Automatic car wash plants h. Under – floor wheel lathe and i. Plant and equipment for maintenance of the infrastructure.

Giving the total equivalent sound level from the point source (MRT Depot Sg. Buloh), noise at specific distances from the point source is calculated using the formula for distance attenuation:

L = L0 - 20 Log D

Where, L = noise level at D meters away from the source;

L0= noise level measured at 1 m from the source; and D = distance from the point source in m.

The noise levels from the point source to the boundary of Lot 488 (comprising medium- high density residential area, Islamic Integrated school, Secondary school, Primary school and affordable housing) is tabulated in Table 6.12 and shown in Figure 6.6.

The predicted noise during the operation of the MRT Depot is in the range of 27.34 dB (A) to 36.88 dB (A) during day time and of 24.13 dB (A) to 33.68 dB (A) during night time on a working day which is much lower than the permissible level of 70.8 dB (A) during daytime and 62.2 dB (A) during night time. The same trend can be observed on a non- working day; where the predicted noise during day time is in the range of 25.54 dB(A) to 35.08 dB(A) and from 23.84 d(BA) to 33.38 dB(A) which is much lower than the permissible level of 69.9 dB (A) during daytime and 61.9 dB (A) during night time.

The noise impact due to the maintenance of trains in MRT Depot Sg. Buloh is not expected to cause any significant impact to the medium-high density and affordable housing units as well as the schools which will be located on Lot 488.

6.5.5 Vibration

The vibration produced during the operational phase is not expected to cause any discomfort or affect health of individuals, as the impact is not considered to be significant. Possible source of vibration disturbances may be produced from traffic operation. Actual measured vibrations from road traffic near the Project site reads at 0.184 mm/s in peak vector sum and the peak particle velocity (ppv) in mm/s at 0.143 (trans), 0.143 (vert) and 0.0952 (long). Based on DOE’s Recommended Limits for Human Response and Annoyance from Short Term Vibrations, vibration from traffic operation should comply with Schedule 6, Curve 8 to Curve 1, the transverse compliance level is between 1.2 to 3.0 mm/s while the vertical and longitudinal compliance level is at 3.2 to 6.3 mm/s.

6.5.6 Traffic Generation

During operational phase, the type of the traffic generated by the proposed Project will be mostly from residential, commercial, mixed use and schools. There will be also an inevitable increase in the traffic volume along Jalan Sg. Buloh, fronting the Project site.

Based on the trip generation exercise, the northern development is estimated to produce 8,372 vehicles/hour and to attract 15,511 vehicles/hour during the morning peak hour. During the evening peak hour, the northern development is expected to produce 19,124 vehicles/hour and attract 14,152 vehicles/hour.

Based on Table 6.15, the road network surrounding the proposed site for the year 2030 would be operating under Level of Service (LOS) between A to E. The traffic projection for Jalan Sg. Buloh, Jalan Lapangan Terbang Subang and Persiaran Surian indicates that there is a need for improvement on the number of lanes provided. The proposed mitigation measures during operational phase will be discussed in Chapter 7.

6.5.7 Socio-Economics

The potential impacts on the socio-economic environment during the operational phase are mainly beneficial or are regarded as being conducive to the social and economic well being and development of the area.

During operation, there will be significant financial gains from the sale or rent of the properties and benefit the State Government in terms of revenues from taxes. Some other benefits that are expected are described below:

 In term of increase in the property values in areas surrounding the Project site as a result of the potential new monies and investments to be brought in by many sectors of the economies in order to meet the demand as a result of increase in population size. However, initially the values are expected to increase significantly, but will stabilize at later stages when all development programs are completed.

 The surrounding region is expected to experience improvements in the physical infrastructures and social services, such as better schools, more housing, electricity, water supply and roads to cater for the enlarged and more economically active population.

 With more new jobs being created the effect will be reduced incentives for emigration among the young members of the local population to seek jobs elsewhere.

6.5.8 Solid Waste Generation

Neither solid waste nor scheduled waste is expected to be generated during the operational phase as the components only involves infrastructures such as road networks, primary infrastructure utility land areas (Water tanks, DCS [District Cooling System]), main drains, waterways and detention / retention facilities.

6.5.9 Abandonment

Although there is always a remote possibility that the proposed Project will cease and subsequently be abandoned in the future, this could only be due to extraordinary and abnormal circumstances such as acts of war or violence, economic collapse or other natural disasters or calamities. In such an event, the option of demolition and removal of the various structures should be considered.

Furthermore, the abandonment of built-up sites creates unaesthetic visual repercussions and a suitable habitat of harboring pests and disease vectors and indulgence in anti-social behavior and activities.

CHAPTER 7: PROPOSED MITIGATION MEASURES

7.1 INTRODUCTION

Various mitigation measures are recommended to be taken to minimise any potential impacts as identified that may occur as a result of the development during the infrastructure works and operational phase. It is important that the mitigation measures to be implemented are integrated into the overall site development plan for optimal control.

It should be noted that a single activity can be the source of more than one environmental impact and may therefore require various mitigation measures. The recommended mitigation measures are for the appropriate impacts such that the activities, potential impacts and mitigation measures are inter-related to one another.

7.2 CONSTRUCTION PHASE

7.2.1 Erosion and Sediment Control Plan

During site clearing, the existing rubber trees and the understory vegetation will be cleared to make way for earthworks for infrastructure activities. Consequently, the exposure of bare, exposed land to natural elements of rain and wind can lead to potential wind and water erosion of the soil substrate.

Various mitigation measures are recommended during the construction phase so that the potential impacts are minimized. The Preliminary/Conceptual Erosion and Sediment Control Plan (ESCP) was prepared based on the requirement of the Department of Environment. The ESCP aims to:

. Reduce and minimize soil erosion and water pollution of the waterways adjacent and within the Project site. . Introduce suitable silt control measures and best management practices for the proposed Project. . Provide guidelines for the implementation of a continuous BMPs monitoring programme.

During the construction phase, the proposed Project needs to comply with the relevant standards and legislation as given in the following table.

Table 7.1: Relevant Standards and Legislation

ENVIRONMENTAL STANDARDS AND LEGISLATION ASPECTS . DOE Guidelines for Prevention and Control of Soil Erosion and Siltation 1978, (revised 1996) Earthworks . DID Guideline for Erosion and Sediment Control in Malaysia, 2010

Environment Asia Sdn Bhd 7-1 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

Table 7.1: Relevant Standards and Legislation (Cont’d)

ENVIRONMENTAL STANDARDS AND LEGISLATION ASPECTS . DID Guidelines (Urban Storm Water Management Manual for Malaysia, 2000) Drainage . DID Guidelines ( MSMA,2nd Edition), 2011 . Street, Drainage and Building Act, 1974 . Environmental Quality (Sewage) Regulations, 2009 Water Quality . Environmental Quality (Industrial Effluents) Regulations, 2009

In order to minimize erosion it is necessary to introduce mitigation measures to control silt runoff from the Project site into the drains or water bodies. Various control measures can be implemented such as limiting the extent of ground exposure, limiting the size of stripped land, surface stabilization treatment (turfing and temporary protective measures such as covering the soil surface with plastic sheets), sediment trapping devices and runoff-control measures such as drainage. These erosion and sedimentation control measures are to be carried out using Best Management Practices (BMPs).

7.2.1.1 Erosion Control

When the infrastructure work begins, soil surface stabilization should be applied to all disturbed areas that will remain undisturbed for periods longer than 14 days. Soil surface stabilization protects soil from the erosive forces of raindrop impact, flowing water, and wind. Erosion control practices include surface roughening, mulching, establishment of vegetative cover and the early application of gravel base on areas to be paved. Effective erosion control will lessen the need for substantial and more costly sediment control measures.

Phasing of Construction Activities

Land clearing limited to the construction of infrastructure works will need to be carried out. Thus, good coordination is vital between the teams responsible for any vegetation clearing and removal and earthworks for the infrastructure development. Once the area has been cleared, earthworks for the infrastructure works should be carried out as soon as possible. Construction activities, especially roadworks should take into consideration the prevailing climatic conditions at that time, particularly rainfall. It is recommended that as far as possible site clearing and infrastructure earthworks to be avoided during the wet season to prevent excessive soil erosion.

Vegetation Buffer

The existing vegetation cover should not be cleared until earthworks for the infrastructure works are ready to begin. Buffer strips or corridors of vegetation should be retained or can also be used to separate disturbed land from an adjacent watercourse, as they control and filter sediments from surface runoff. Buffer strip performance generally increases as buffer width increases or as the buffer slope decreases. A minimum width of buffer strip should be no less than 10m.

Environment Asia Sdn Bhd 7-2 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

Temporary Covers

If turfing cannot be carried out immediately at the exposed areas, temporary covers such as plastic sheets, geotextile or fibre mats can be used instead. The use of temporary covers, which is either made of natural or synthetic material, can be used to cover up the exposed soil to reduce erosion due to rainfall impact and surface flow.

7.2.1.2 Sediment Control

Sediment controls must be constructed before land disturbance takes place or at the very least concurrent with the site clearing at areas where infrastructure works will be carried out. Sediment control will be site specific and can include vehicle tracking controls, sediment barriers, silt traps or sediment basins; or a combination of any or all of these measures to prevent the movement of eroded sediment from being transported off-site. Some sediment controls can also be used for containment of the work site to prevent the inflow of off-site waters into the site and adding to the sediment load within the Project site.

Sediment Basins

A total of 4 sediment basins will be constructed within the northern Project site to trap surface runoff from the proposed site during the earthworks for the infrastructure works. All discharges from the sediment basins will flow into temporary culverts before discharging into the external drains and waterways. The calculation of the sediment basins is indicated in Table 7.2. The proposed locations of the sediment basins are shown in Figure 7.1 and the conceptual/preliminary ESCP is attached in Appendix 7.

Table 7.2: Sizing of Sediment Basins

SEDIMENT BASIN (SB) LENGTH (L) WIDE (W) DEPTH (D) Sediment Basin 1 151.20 m 76.20 m 2.70 m Sediment Basin 2 91.20 m 46.20 m 2.55 m Sediment Basin 3 101.20 m 51.20 m 3.15 m Sediment Basin 4 51.20 m 26.20 m 2.75 m

Drainage Control

Before commencement of earthworks for the infrastructure works at the northern portion, temporary drains shall be constructed to channel surface runoff for control of sediment discharge. Perimeter drains are important to prevent any sediment laden runoff from the site flowing off-site and conversely also to prevent surface runoff from off-site from entering into the site. Drainage provisions within the site and downstream should be adequate to ensure that no flooding occurs. The sizes for the earth drains are as shown in Table 7.3.

Environment Asia Sdn Bhd 7-3 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

Depth

Width

The temporary earth drains must be adequately compacted and the sides cut to slope and maintained to prevent collapse of the sidewalls. If at all possible, stronger temporary drains in the form of pre-cast concrete drains are recommended. If site conditions and space permits, wider diversion drains and dykes should be constructed and where the flow is greater than 0.6 m/s, check dams shall to be constructed to slow down the velocity of flow.

The drainage system should be regularly inspected and maintained especially after heavy rainfall. Runoff from the cut and fill areas should be released into temporary drains that flow into the sediment basins. The temporary drainage should be altered as and when necessary to keep the site free of standing water. All runoff from undisturbed areas should not be allowed to mix with runoff from disturbed areas. This can be achieved by constructing contour banks at the downstream boundaries between every disturbed and undisturbed area. Surface runoff from the temporary drainage should be directed into the sediment basins to prevent direct ingress of silt into existing natural streams / waterways. The locations of all the temporary drains, temporary culverts and temporary waterway crossing at the Project site are as shown in Figure 7.1

Washing Bay and Stabilized Construction Access

The wheels and undercarriage of trucks exiting the site to drive through a wash trough to clean the wheels and undercarriage. The wash water is to be recycled through the sediment settling sump and any overflows directed into the perimeter drain that lead into the sediment basin.

The stabilized construction access for the exit should have a paved or concrete slab minimum 10m length or a gravel run of 15m with 15cm gravel depth and 5cm sized aggregate. The access area to have bunds or drains to channel water back into the sump or sloped back towards the sump and a low bund or cut-back curb to prevent wash water from flowing onto the public roads and drains. The location of the construction access and wash troughs (2 wash troughs) are as shown in Figure 7.1.

Environment Asia Sdn Bhd 7-4 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

7.2.1.3 Best Management Practices (BMP)

Stage 1: Site Clearing for Infrastructure Works  Construct temporary drains / temporary culverts and temporary water crossings.  Construct sediment basins.  Construct stabilized construction access and wash trough.  Felled rubber trees to be sold for the manufacturing of furniture and not disposed off.  The removed topsoil is to be stockpiled for later use during landscaping.

Stage 2: Infrastructure Works  Where the gradient of the temporary earth drains result in drainage flow velocity >0.6m/s, check dams shall be constructed to slow down the flow and assist in sediment settlement. The distance between check dams is dependent on the gradient and height of the check dams e.g. a gradient of 1% with check dam height of 1m will have 100m distance separation between successive check dams.  Slope protection where necessary with bio-mats or turfing to be carried out.

7.2.2 Cut / Fill Slopes

The existing level at the northern Project site is between 24 m and 62 m. Cut and fill activities will be carried out to achieve platform levels of 27 m to 44 m for the infrastructure works. Figure 7.2 shows the earthwork layout plan for the infrastructure works of the northern development under MBSA while Figure 7.3 shows the cross section of the cut and fill works.

Earthworks shall be carried out in accordance with the recommendations in the British Standard BS 6031:1981 Code of Practice for Earthworks. The cut and fill slopes should be designed to the appropriate factor of safety. All cut and fill slopes shall be trimmed to 1:15 and 1:2 gradients, respectively. Cut slopes will be trimmed to maximum heights of 4 m before 1m berms and cut-off drains will be introduced. For fill area, slopes maximum fill heights will be 3 m between berms.

Earthworks shall comprise excavation in all materials, backfilling and compaction, forming embankments and slopes etc. as necessary for the completion up to platform levels of the infrastructure development. Platform levels will be designed to best suit the service to be provided by the respective utilities and to avoid ancillary mechanical support in delivery of the system i.e., locating the reservoirs at the highest platform possible and detention ponds at lowest point available, etc.

Compaction trials supplemented by the necessary field tests described in British Standard 1377 (Methods of Testing Soils for Civil Engineering Purposes) shall be carried out before the compaction works commence.

The fill shall be of "suitable material" in accordance to BS 1377. Filling material shall not be laid on top of debris left over from clearing. In general, the material from cut areas of the site is acceptable for fill and shall be used throughout.

Environment Asia Sdn Bhd 7-5 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

The standard compaction to be achieved shall be in accordance to B.S. 1377 where in- situ sand replacement method shall be used to determine the density of the soil. The level of compaction to be ascribed shall be as follows:

7.2.3 Hydrology and Flooding

The hydrological regime of the Project site could be altered during the construction phase mainly due to the clearing of the vegetation where the infrastructure works will be carried out. An increase in surface run-off is expected. The recommended mitigation measures to be undertaken during the construction phase include:

Avoid existing waterway diversion

 During earthworks, the surface runoff from the site is not significantly increased as site clearing and earthworks is limited to the infrastructure works for roads and utilities.

Surface Runoff Control

 Temporary drainage will be constructed to channel surface runoff into the sediment basins prior to discharging into the existing drain / waterways.  The sediment basins and temporary drainage system shall be designed according to the MSMA 2nd Edition guidelines to ensure its capacity is sufficient to intercept the flow and to slow down its velocity in order to promote settlement.

Maintenance of Best Management Practices (Sediment basin and temporary drainage)

 Maintenance of the sediment basin and temporary drainage must be carried out on a regular basis to ensure they are not overloaded or clogged as this may lead to localized flooding.  Proper disposal of biomass and construction debris should be practiced to ensure clogging of the waterways and drainage does not occur.

Figure 7.1 shows the flow of surface runoff from the temporary drainage to the sediment basins prior discharging into the existing drains and waterways of the Project site.

7.2.4 Water Pollution

The sources of water pollution and the control measures that should be carried out to prevent and reduce the deterioration of the water quality of the adjacent waterways are detailed as below. The appointed contractor should monitor the water quality and any impairment or pollution caused directly by the contractor’s works should be rectified.

Environment Asia Sdn Bhd 7-6 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

7.2.4.1 Oil and Petroleum Products / Machinery / Workshops

The need and locations of any workshops / maintenance areas can only be determined during the detailed design stage and will be highlighted in the Environmental Management Plan. However, some of the mitigation measures that shall be implemented are as described below:

 The presence of diesel machinery and the storage of diesel and petroleum products may lead to oil pollution should spillage/leakage occurs. Hence, adequate attention should be given to storage and refueling activity.  Diesel skid tanks and oil drums must be placed within a sheltered, paved bunded area and the drainage outlet provided with an oil sump or interceptor.  The maintenance of machinery should be carried out in a designated area where spillage or leakage of used oil and lubricants can be contained.  Oil spills should be cleaned up as soon as possible to prevent possible oil contamination to the waterways.  Used oil and grease should be stored in proper drums/containers, labeled and placed at a designated location with containment facilities as far away as possible from waterways, prior to disposal by licensed contractors.  Adequate attention should be given to maintenance of the construction machines to ensure that leakage does not occur.

7.2.4.2 Cement / Bitumen

 Cement/ bitumen should be stored properly in working shed.  Unauthorized dumping into waterways and on the roadside is not allowed.

7.2.4.3 Sanitary Facilities

There should be provisions of adequate temporary toilet facilities (either septic tank or portable toilet). The system should be in accordance with the Sewerage Services Department (SSD) and Ministry of Health (MOH) specification. Effluent, if any, should comply with Standard B of the Environmental Quality (Sewage) Regulations, 2009.

7.2.4.4 Construction Debris

All construction wastes and debris are to be collected and transported for final disposal at the designated municipal dumpsite. Temporary collection areas are not to be placed near waterways to prevent wastes and debris from washing into the waterways.

7.2.4.5 Scheduled Waste

Storage and handling of scheduled waste should be carried out according to the Environmental Quality (Scheduled Wastes) Regulations, 2005, such as:

 The wastes should be stored in sealed drums, labeled and placed in a proposed scheduled waste storage shed.  The shed should be concrete paved, bunded with a capacity to contain 110% of the largest container volume.

Environment Asia Sdn Bhd 7-7 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

 There should not be any opening in the bund wall that may allow leakages and spills to flow off-site.  Separate compartments should be provided for different groups of incompatible wastes.  Scheduled wastes should not be kept on site for more than 180 days or exceed 20 tonnes.

7.2.5 Air Pollution

During the construction stage, the main emissions into the atmosphere would be fugitive dust. The control of fugitive dust can be effectively achieved by employing good housekeeping. In addition, any significant amount of emissions from large numbers of

construction vehicles could increase the NOx, SOx and CO levels in the ambient air. It is recommended that the following mitigation and abatement measures be applied during the construction phase:

 Employing good housekeeping to control fugitive dust effectively.  Open burning of construction debris or felled vegetation shall not be allowed under any circumstances.  Heavy machineries and construction / transportation vehicles should be maintained and checked regularly to ensure there are in good working condition in order to minimize smoke and soot emissions into the atmosphere.  Vehicles transporting construction materials for road works or debris should be properly covered with canvas/plastic sheet and secured properly to minimise dust and particulate dispersion to the surrounding atmosphere.  The on-site road network must be in a good service condition.  Driving speeds of vehicles within the construction site should be limited to 30 km/hr to reduce soil dislodgement and dispersion.  Wash troughs as shown in Figure 7.1 will be provided at the exit point of the Project site onto the public right-of-way in order for the wheels of the heavy vehicles to be properly cleaned prior to allowing them to exit the Project site.  Constant wetting and cleaning of access road connecting the work site to the external public roads (Jalan Sg. Buloh). Water bowser should be maintained especially along Jalan Sg. Buloh.  Regular air monitoring should be carried out to monitor the possible degradation of the existing air pollution.

7.2.6 Noise

The noise impact is deemed insignificant as only infrastructure works will be carried out. However, some mitigation measures that should be implemented in order to minimize the extent of the noise pollution to the nearby receptors are as follows:

 Driving speeds of vehicles within the construction site should be limited to 30 km/hr.  Construction activities and vehicle movements should be confined to daytime periods, which is from 7 a.m. to 7 p.m.  All construction workers, who are involved with extensive noise emission activities, should be equipped with hearing protective devices such as ear-muffs. In addition to

Environment Asia Sdn Bhd 7-8 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

this, warning signs should be installed at high-level noise areas to alert workers of the noise danger.  Noisy machineries / equipment should be preferably be placed as far away from the northeast boundary of the Project site where the nearest residential area, Section 8 Kota Damansara is located.  Hoarding as shown in Figure 7.1 will be set up around the site’s boundary as a temporary noise barrier during the construction period.

7.2.7 Vibration

During the construction phase of the infrastructure works, there is no significant increase in vibration as no piling works will be carried during this stage.

7.2.8 Traffic

Many of the factors that affect traffic flow and safety of road users can be mitigated or minimized through the adoption of specific measures within an effective Traffic Management Scheme (TMS) that is to be implemented at all construction sites especially at road access and traffic junctions. The TMS is to be implemented over the entire duration of the construction phase. The TMS should include measures for regulating traffic at the access points from the main roads and would include the installation of appropriate warning signs, lights and the use of traffic wardens to direct traffic in line with JKR and local authority requirement for safety at construction sites.

In addition, the following is also recommended:

 Transportation of heavy loads of construction material for road works and machinery should be undertaken preferably during off-peak traffic hours  Scheduling to avoid large convoys of trucks arriving / exiting the site at the same time  Planning of access routes to avoid narrow roads or residential service roads  Use of multiple or separate entry and exit points if possible to spread out traffic distribution  When traffic is busy, flagmen should be employed to assist in the direction of traffic when construction vehicles are joining into the main flow of traffic

On the overall, these impacts are expected to be relatively short term and with proper traffic control, the risks and inconvenience to other road users can be minimized. Proper traffic control plan shall be implemented to prevent any mishaps due to the transportation of material into and out of the site. Warning signs will be installed to alert road users as and when needed.

7.2.9 Ecological Aspects

The removal of vegetation from the northern Project site is inevitable during site clearing for the infrastructure works. Site clearing will be conducted where necessary and in stages to minimize soil erosion and siltation while sediment basins will be constructed to prevent silt-laden runoff from discharging into the existing waterways.

Environment Asia Sdn Bhd 7-9 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

The rubber trees will be sold for the manufacturing of furniture while other vegetation foliage will be mulched and composted on site where possible. Out of the 337.699 tonnes of biomass anticipated, approximately 200 tonnes are the rubber trees which will be recycled. The remaining biomass will be placed at selected locations within the site that has been earmarked as stockpile area for composting (Figure 7.1). Due to space limitation, some of the excess vegetation will be disposed of at the municipal dumpsite approved by Majlis Bandaraya Shah Alam (MBSA) and not thrown into the drainage path/ waterways. This is to avoid blocking of waterways and flooding during heavy rain. Dumping of felled shrubs and foliage may cause the deterioration of the water quality.

Burning of cut vegetation is strictly prohibited to avoid deterioration of the atmospheric quality. Landscaping and/or turfing should commence as soon as possible. Landscaping can provide an aesthetically pleasant surrounding. Appropriate landscaping could also help to reduce soil erosion.

7.2.10 Socio-Economic Considerations

7.2.10.1 RRIM Estate Workers

The welfare of the estate workers remains under the purview of RRIM. The estate workers were relocated to other estates in early 2014.

7.2.10.2 Employment of Construction Workers

Upon commencement of the construction phase, preference should be given to local workers for the employment opportunities within the proposed Project or the nearby residents. The employment of foreign workers should only be considered when local workers could not be engaged and as the last option. It is recommended that foreign workers, if employed, should be closely supervised to avoid any untoward incidents with the local community. As a preventive measure all foreign workers need to be medically screened for potential carrier of diseases. All young persons under the age of 18 are not allowed to work at the construction site.

7.2.10.3 Workers’ Quarters / Base Camp

In order to avoid any potential disruptive social impacts on the local communities adjacent to the site which are not equipped with the public facilities, infrastructure and services necessary to accommodate them, self-contained work camps designed to feed and house the influx of the workers, in particular foreign workers, are preferred. This isolation– insulation strategy is useful to avoid possible social unease but also to minimize demographic effects on the local communities. This would relieve demands on existing social and community services, infrastructure and potential impacts on community composition, interactions, values and behaviors as a result of differences in cultures between the foreigners and the locals.

If a base camp is to be constructed, it should be ensured that proper housekeeping and hygiene be maintained at all times. Sewage and solid waste from the site office and work areas have to be properly disposed in order to ensure no water contamination occurs. Therefore, temporary sanitary facilities (septic tank or portable toilets) should be provided

Environment Asia Sdn Bhd 7-10 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

for workers in accordance with the requirement of Jabatan Perkhidmatan Pembetungan (JPP). This will reduce the concern on public health hazards related to the generation of sewage and solid waste residues. Other measures to ensure that the site camp is well maintained are:

 Adequate bins for domestic and general waste must be provided with a schedule for disposal to eliminate problems of littering and improper solid waste disposal. This will reduce any potential concern on public health related to generation of sewage and solid waste residues.  Debris and abandoned materials that may attract rodents and other pests to the construction site must always be cleared. Fogging should be carried out regularly and more frequent if there is any suspicion of rodent infestation or breeding of mosquitoes.  All construction materials and construction debris need to be properly kept so as to prevent the area from becoming breeding grounds for mosquitoes and rodents.  Remaining food and wrappers must be disposed in covered containers to discourage foraging stray animals away from the construction site.  Clean water should be provided for the workers. If the water is not meant for drinking purposes, a separate water supply should be provided. Proper bathing and washing facilities should be provided at the site camp.

7.2.10.4 Occupational Safety Aspects

There should be stringent adherence to occupational health and safety regulations to prevent injuries, including information and education for workers on the importance of safety precaution.

During the land clearing and construction stage, clear signboards and lights to indicate and highlight danger areas should be put up. Construction safety shall be strictly adhered to and construction workers should be well trained so as to minimize and avoid accidents at the work site. Adequate first aid facilities should also be made available on site. The main purpose is to avoid or minimize occupational as well as accidental hazards to the public as well as the workers.

To achieve this purpose, various measures can be taken such as:

 A safety and health policy. The policy shall be displayed at prominent locations where it is easily accessible by the workers. It must be written in simple concise form such that it is easily understood by all workers and it should be communicated to them through a briefing session.  A competent safety officer shall be employed to oversee the safety and health aspects of the construction site.  Daily site inspection should be carried out by the area supervisors.  A traffic circulation plan should be established onsite to control the traffic movement. Traffic direction (one-way) and speed limit of 30 km/h or lower is recommended for construction site.  The need to install proper and effective traffic control system so that other road users are aware of the potential dangers from heavy vehicles during construction period, especially at the entry/exit points to/from the Project site,

Environment Asia Sdn Bhd 7-11 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

 All construction materials should be kept in a designated store or area. Hazardous and flammable materials shall be labeled and kept separately from other materials.  Manual handling for heavy materials should be avoided as much as possible. Mechanical aids such as trucks and backhoe should be used to carry heavy loads.  Cables of power tools shall always be in good working condition. Worn cables should be replaced immediately. Proper plug shall be provided for all power tools. Illegal power connection (bare wires directly connected to power point) should not be allowed. All generator sets used in the construction site must be properly earthed.  The employer shall provide adequate and suitable personal protective equipment (PPE) to his/her workers who are exposed to hazards that can cause bodily injury.  All construction activities should stop when night falls.  Any accidents within the construction site must be reported to the safety and health officer who shall then initiate investigation to prevent recurrence of similar accident onsite.

7.2.10.5 Public Safety and Health

In order to increase the level of awareness among the local communities about the proposed Project, relevant information need to be disseminated to the public prior to Project commencement. Community liaison shall be initiated to provide information on the work schedule, work areas and potential hazards to the public of the potential danger at specific locations surrounding the Project site.

Precautions need to be taken to avoid accidents at the point of entry to the Project site, in particular at major junctions and along Jalan Sg. Buloh. All drivers of heavy vehicles carrying building material to/from the Project site need to be reminded/made aware of the danger they pose to other road users when travelling along Jalan Sg. Buloh.

Any massive influx of workers (approximately 300 pax), particularly foreign workers, may create some social problems in terms of public safety and social harmony. To avoid such problems the workers for the Project should be segregated from the local residents. The workers should be advised to behave in a socially responsible manner and not to disturb the local people.

Foreign workers need to be relocated some distance from the local population so as to avoid direct contact with the local population and hence preventing potential crime to be committed or the spread of potential diseases which have been eradicated from our environment such as tuberculosis, hepatitis, malaria etc. The foreign workers should be medically screened for infectious diseases.

Upon commencement of the construction phase, there could be various potential health risks associated with the work site. General hygiene is an important factor during the construction phase, as unkempt and dirty working areas will provide breeding grounds for flies and rats. Hence, mitigating measures as follows should be taken into consideration:

 A proper drainage system is necessary as well as frequent disposal of construction and waste materials / products to eliminate breeding grounds for mosquitoes on the construction site and surrounding areas.

Environment Asia Sdn Bhd 7-12 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

 Work areas should be kept clean at all times. Garbage and solid wastes should be disposed into the designated waste bins and stored at a designated location prior to disposal off-site by licensed contractors.  There should be adequate provision of proper sanitation facilities for workers.  No open burning should be carried out.  Ensure that if food stalls are operating near the construction site, these are hygienic and licensed; and  Food wastes should not be discarded indiscriminately on site to prevent proliferation of pests such as rats.

Proper safety signages e.g. “Construction Area, Do Not Enter” should be posted at the entrances of the construction site to warn the public.

7.2.11 Solid Waste and Scheduled Waste

7.2.11.1 Solid Waste Management

All solid wastes generated from the northern construction site shall be collected at a central area prior to disposal. No open burning of solid wastes shall be carried out at any time. All solid wastes from the site must be regularly removed and disposed by licensed contractors. Regular de-sludging of the portable and/or septic toilets from the site camp should be carried out.

7.2.11.2 Scheduled Waste Management

Any wastes contaminated with petroleum products, if any, shall be treated as Scheduled Waste in accordance with the Environmental Quality (Scheduled Wastes) Regulations, 2005. Mitigation measures to be implemented for the waste management are:

 Storage and handling of scheduled waste should be carried out according to the Environmental Quality (Scheduled Wastes) Regulations, 2005. The wastes should be stored in sealed drums, labeled and placed in a proposed scheduled waste storage shed. The shed should be concrete paved, bunded with a capacity to contain 110% of the largest tank volume.  There should not be any opening in the bund wall that may allow spills to flow off-site.  Separate compartments should be provided for different groups of incompatible wastes.  Scheduled wastes should not be kept on site for more than 180 days or have a volume exceeding 20 tonnes.

7.2.12 Abandonment Plan

In the unlikely event that the proposed Project cannot proceed and has to be abandoned due to unforeseen circumstances, the Project proponent must endeavor to vacant the Project site in an environmentally responsible manner and prepare a Project Abandonment Plan.

The main objective of the site abandonment plan is to ensure that the Project proponent closes down their operation in an environmentally responsible manner. The site should be

Environment Asia Sdn Bhd 7-13 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

left in the best shape possible in terms of the environment. It should also be free of any unexpected hazards to the public. The abandonment plan indicates all the necessary actions and steps to be taken to achieve the objective above and ensure that the site is left in a condition that has no environmental implications.

In general, the abandonment plan should include an inventory of materials and equipment and their removal. It will provide details on the demobilization and removal of temporary and semi-built structures, and the closure of work sites.

The Plan should include the following:  Identification of environmental issues such as wastes and hazards  A remediation or rehabilitation plan for the Project site  A schedule for decommissioning, dismantling of temporary structures and removal of equipment/machinery  Documentation of the activities carried out for the abandonment plan

Table 7.4 summarizes the abandonment plan during the construction phase.

Table 7.4: Abandonment Plan during Construction Phase

STAGES OF ABANDONMENT AND CLOSURE PLAN DEVELOPMENT PROJECT PARTIALLY COMPLETED AND ABANDONED Site clearing  Before abandonment, all cleared and scarred areas have to be revegetated.  Excavated areas should be filled to avoid open trenches.  The sediment basins and temporary drains should be filled, compacted and turfed to reduce problems of ponding.  The site should also be free from standing water to avoid breeding of mosquitoes.  All debris arising from site clearing will have to be cleared and exposed areas turfed and ‘dressed’ back to their original condition as far as possible to reduce soil erosion and pollution of the existing waterways.  All wastes generated during this stage should be removed and disposed off properly.  Danger signboards should be erected at the boundary of the northern Project site to warn off trespassers. The area should be cordoned-off by hoarding until such times when it could be revived.  All unsafe structures be dismantled and debris on the site be removed.

Infrastructure  If the infrastructure work is abandoned half way, then the works relevant authority and agencies responsible for the supply should be informed and liaison with them for a safe closure or removal.

7.3 OPERATIONAL PHASE

7.3.1 Drainage and Hydrology

The major hydrologic changes accompanying the northern Project development are changes in the surface characteristics due to the increase in impervious area. The stormwater master plan for this development is designed and planned in accordance to the guidelines listed below:

 The Urban Stormwater Management Manual for Malaysia (MSMA)(DID,2000)  The Urban Stormwater Management Manual for Malaysia 2nd Edition, MSMA 2nd Edition, DID, 2011)  The DID Manual (DID, 2009)  The Sungai Damansara Flood Mitigation Master Plan (DID, 2009)

BIOECODS is made up of several important components that ultimately from an efficient stormwater treatment train that control runoff quantity and preserve runoff quality. The BIOECODS is designed:

a) to provide time for natural processes of sedimentation, filtration and biodegradation to occur, which reduces the pollutant loads in stormwater runoff b) to blend easily into their surroundings, adding considerably to the local amenity and / or local biodiversity. c) to combine infiltration, delayed flow, storage and purification as pre-treatment of stormwater before discharging to receiving waster body.

For this development, 4 detention ponds are proposed to be constructed.

BIOECODS here includes a series of components such as grassed swale, bioretention, engineered channel, constructed wetlands, detention storage, etc as part of the BIOECODS that contribute to the treatment of the stormwater. In addition to source controls, these measures include integrating large-scale landscapes into the development as a major element of the stormwater management system. The concept of the BIOECODS is to integrate with the Ecological Ponds for further treatment of the stormwater runoff. In combination, these increase runoffs lag time, increase opportunities for pollutant removal through settling and biofiltration, and reduce the rate and volume of runoff through enhanced infiltration opportunities. Finally, this has been embodied in the concept of ecologically sustainable solution to the flooding and pollution problems using the "control at source" approach, as well as in the concept of ecologically sustainable development which is aimed at ensuring that development can occur without long-term degradation of natural resources and the environment.

Figure 7.4 shows the proposed drainage system for the development while Figure 7.5 shows the drainage with JPS Drain Reserve, Bioretention and Bio- Ecological drainage.

The 4 proposed detention ponds will be located at strategic areas throughout the development area as shown in Figure 3.1.

7.3.2 River Reserve

A minimum reserve should be established so that there is a clear authority to prevent unauthorized felling of trees or clearing of vegetation and undesirable activities affecting river banks. The proposed river reserves for main rivers within the MBSA development based on pre-consultation from Department of Irrigation and Drainage Malaysia (REDAC, 2014) are shown in Table 7.5.

Table 7.5: River Reserves

RIVER TOTAL RESERVE WIDTH *Sg. Kedondong 50M *Sg. Paku 50M Source: REDAC, USM, 2014

7.3.2.1 River Crossing

There is a need to construct new river crossings at Sg. Kedondong, Sg. Paku, Sg. Payong and Sg. Rumput by using precast arc culvert for the proposed Project. The proposed precast arc culvert is a cost effective solution without affecting much the hydraulic efficiency. Besides that, the design has longer service life with virtually minimal maintenance. Precast components can be handled and installed quickly to minimize complication during construction.

7.3.3 Water Pollution

Sewer discharge from the overall development will be channeled to the Sewage Treatment Plant located at the southern portion of the development (under the jurisdiction of MBPJ). The sewerage conveyance system shall be designed to cater for domestic wastewater excluding stormwater. As such, there must be no linkages to allow from any stormwater flows into the sewerage conveyance pipes.

The maintenance and operation of the sewage treatment plants will be under the jurisdiction of Indah Water Konsortium and the quality shall be maintained to Standard B of the Environmental Quality (Sewage) Regulations, 2009.

7.3.3.1 River Water Quality Treatment Facilities

As this Project is planned to become a showpiece of the new management concept using sustainable urban drainage (SUDS), integrated stormwater management approach will be fully adopted in formulating Stormwater Drainage Master Plan for the township development and to meet the technical requirements of the Urban Stormwater Management Manual for Malaysia in all drainage system.

However, from the past study and site observation, the existing river flow contributing to the Project site area from upper catchment may be in low quality (REDAC, 2014). Therefore, an initiative has been taken by Kwasa Land Sdn Bhd to allocate a total of 3.95 acres for two separate treatment facilities within the development area, as tabulated in Table 7.6 and shown in Figure 3.1.

Environment Asia Sdn Bhd 7-32 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

RIVER AREA OF WATER QUALITY TREATMENT FACILITY (ACRES) NORTHERN DEVELOPMENT (MBSA) Sg. Kedondong 1.82 Sg. Paku 2.13 TOTAL AREA: 3.95

7.3.4 Air Pollution

The problem of air pollution is expected to decrease significantly during the operational phase since the Project is a residential with public infrastructures in nature. No specific mitigation measures are necessary for the development.

7.3.5 Noise Pollution

7.3.5.1 Road Traffic

Any potential source of noise pollution will be of vehicular movements within the roads of the completed development. The recommendation for the traffic management will be discussed in the following sections.

Based on the noise modeling, the maximum noise level at Section 8 Kota Damansara along Jalan Sg. Buloh upon full Project completion is expected to be about 64.4 dB(A) and 61.3 d(BA) during the morning and evening peak hours, respectively. The noise levels are within the DOE’s Schedule 3: Maximum Permissible Sound Levels to Be Maintained at the Existing Noise Climate, LAEQ (existing level) + 3dBA of the Planning Guidelines for Environmental Noise Limits and Control, 2007. Therefore, no additional mitigation measures are required.

7.3.5.2 MRT Depot

Noise assessment was carried out in February 2014 facing the existing LRT Depot Lembah Subang at Ara Damansara where maintenance works were carried out. Based on the assessment (as discussed in Chapter 5 and Chapter 6), the noise impact due to the maintenance of trains in MRT Depot Sg. Buloh is not expected to cause any significant impact to the medium – high density and affordable housing units as well as the schools which will be located on Lot 488. The allocation of buffer zone will be further discussed in the following section.

7.3.6 Vibration

There will be no source of potential vibration impact during the operational phase and as such no mitigation measures are proposed.

Environment Asia Sdn Bhd 7-33 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

7.3.7 Buffer Zones and Green Areas

The objective for the proposed Kwasa Land Sdn Bhd Landscape Master Plan is to create a new focal point(s) that reflects a township of the 21st Century and that is as sustainable as possible where it shall also be or allow for the possibility of income generation through the parks or open space or any green areas or space design by introducing elements, amenities and/or activities that could attract users and be self-sustaining. The proposed design shall be Biodiversity, Pedestrian Friendly, Green, Connected and Safe City that shall contribute to the Quality of Life and has a sense of Place Making.

For this northern development, a total of 46 acres (6.78%) will be allocated for landscaping purposes, which includes the linear park/green area. The overall landscape of the development is shown in Figure 7.7.

Buffer zone between 80 m to 280 m has been provided within the MRT boundary from the track to the Project boundary. An addition of 20 m (road reserve) buffer will be provided within the Project land. The cross sections of the buffer zones are shown in Figure 7.8.

7.3.8 Traffic Management Scheme

Based on the traffic study, some of the recommendations which should be taken into consideration to ensure a better performance of the road network in the Project area are discussed below:

7.3.8.1 Major Access Point

A good traffic control is essential to ensure a better access to the development. Thus, all major access to the development is proposed to be controlled with a signalized junction or interchanges. For this particular development, Jalan Sg. Buloh will act as the main access which direct traffic from various directions to the development. Thus, an extensive and effective access point should be designed to cater the traffic load onto the development. The access points along Jalan Sg. Buloh are proposed to be diamond interchange. The summary of proposed access points are as follows:

 1 multi-tier interchange (connection between DASH - Jalan Sg. Buloh - Kwasa Damansara main spine)  2 Diamond Interchange at Persiaran Jati and Persiaran Sg. Buloh  6 signalized junction for the internal road of Kwasa Damansara – MBSA portion

The locations of the major access point and the proposed diamond interchange are shown in Figure 7.9.

7.3.8.2 DASH Highway

The Damansara - Shah Alam Elevated Expressway (DASH) is planned to provide east- west between the areas of Shah Alam, Batu Arang / Guthrie Highway and Damansara/ Kuala Lumpur. This Highway is envisioned to facilitate a vital east-west corridor link between the regions of Shah Alam / Guthrie and Damansara. The Damansara - Shah Alam Elevated Expressway (DASH) is proposed to commence at the Shah Alam - Batu Arang Highway adjacent to Bukit Cahaya/Kayangan Heights development. From this point, the proposed highway runs along road reserve between Sunway Alam Suria and SPK Cahaya and will have an interchange connecting it to the Guthrie Highway. Beyond this interchange, the highway runs on east-west alignment elevated along Jalan Sg. Buloh. From here, the proposed highway cuts into the RRIM Reserve, where it forms an interchange of Subang Airport Interchange and RRIM Interchange. Along the Guthrie Corridor Expressway Interchange to Subang Airport Interchange, there are on ramps and off ramps at Kg. Melayu Subang area, Subang Perdana area and Kg. Melayu Subang Tambahan area (Kg. Melayu Subang 2, Subang 2 Interchange, Galaksi Interchange).

Subsequently the highway travels transverses into the southern section of the RRIM reserve prior to forming an interchange at Persiaran Surian.

DASH will provide a Highway route, between the centers of strategic importance, facilitating an alternative route to the presently congested road network between Petaling Jaya, Sg. Buloh, Kota Damansara and Shah Alam. By providing this alternative route, it will promote and enhance the attractiveness of the townships and commercial centers

Environment Asia Sdn Bhd 7-38 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

located in the eastern region of Selangor including the proposed Sg. Buloh New Township (RRI).

With the DASH running through the major access of this township, the current traffic especially from Jalan Sg. Buloh will then be shifted and the traffic is expected to be reduced. A 35% reduction on Jalan Sg. Buloh was adopted based on the traffic forecast study and this will ease the congestion of the future traffic along Jalan Sg. Buloh especially when the proposed township is fully completed.

7.3.8.3 Dispersal of U-Turn Traffic at Persiaran Cakerawala

Based on the traffic plan for the development, a new spine road (40m ROW) is proposed to help alleviate traffic from Jalan Sg. Buloh and Jalan Lapangan Terbang Subang. With this spine road in place, the pattern of existing traffic flow will also change.

Based on the existing traffic pattern, the traffic bound to Jalan Sg. Buloh (westbound) and to Jalan Lapangan Terbang Subang from Persiaran Cakerawala utilizes the existing signalized U-turn at the RRI signal junction. Based on the future analysis, this signal junction will not be able to cater for the additional traffic volume and as such have been incorporated into the design of the multi-tier interchange between Jalan Sg. Buloh, proposed Spine road and DASH. Due to constraint in space, the U-turn for traffic from Persiaran Cakerawala will have numerous alternatives to reach Jalan Sg. Buloh (westbound) and Jalan Lapangan Terbang Subang.

With these alternatives routes, the study feels that the traffic movement in the locality will be more dispersed thus relieving Jalan Sg. Buloh (west bound) and Jalan Lapangan Terbang Subang as well as to Guthrie Highway.

7.3.8.4 Junction Upgrading

The overall upgrading by Kwasa Land is as follows:

a. Junction J1 (Jalan Lapangan Terbang Lama – Jalan Lapangan Terbang Baru)  From 3 arm signalized junction to 4 arm signalized junction  Additional lanes at the entire arm

b. Junction J2 (Jalan Lapangan Terbang Lama – Jalan Lapangan Terbang Baru)  From 3 arm signalized junction to 4 arm signalized junction  Additional lanes at the north, south and east arm

c. Junction J5 (Jalan Sg. Buloh – Persiaran Sg. Buloh 3 arm junction) - Interim Phase (Year 2022)  From 3 arm signalized junction to 4 arm signalized junction  Additional lanes at the entire arm

- Beyond the Year 2022  From 4 arm signalized junction to a diamond interchange

Environment Asia Sdn Bhd 7-39 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

d. Junction J6 (Jalan Sg. Buloh – Persiaran jati 3 arm junction) - Interim Phase (Year 2022)  From 3 arm signalized junction to 4 arm signalized junction  Additional lanes at the entire arm

- Beyond the Year 2022  From 4 arm signalized junction to a diamond interchange

e. Upgrading Jalan Sg. Buloh from dual two to dual three for a total distance of 4km.

f. Spine road that will be as an alternative road to Jalan Sg. Buloh which functions as a dispersal access to major area.

7.3.9 Socio-Economics

During the operational stage and when the Project is fully completed, the mitigating measures to be taken are as follows:

 The increased in activities of cars or motorcycles to and from the Project site necessitates improved installation of sufficient road signs and safety features to prevent accidents involving the residents and other users using the same road; and  Foreign workers involved in construction works should be demobilized according to proper procedures and either re-located to other Project sites or return to their country as per their work permits.  All unused materials should be cleared to prevent the area from becoming breeding grounds for mosquitoes and rodents to curb vector-borne diseases from recurring.  Any significant increase in demand for social facilities should be matched with the corresponding equal amount of additional funding to improve and to expand the existing social facilities.

7.3.10 Waste Management

7.3.11 Abandonment Plan

In the event of abandonment of the Project during the operational phase, which is a most unlikely event, the following measures have to be taken:  All relevant authorities have to be informed by the Project Proponent of closure and abandonment.  The Project site needs to be fenced up for security reasons. Warning signs have to be installed to prevent unauthorized entry.  Removal and proper disposal of all types of wastes on-site.  Dismantling and removal of all equipment that may cause injury.  Implementation of the relevant rehabilitation plan, if an adverse environmental condition has been created.  The area should be checked for damaged live wires that could pose a threat to anyone who trespasses into the area.

Environment Asia Sdn Bhd 7-44 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

CHAPTER 8: ENVIRONMENTAL MANAGEMENT PLAN

8.1 INTRODUCTION

The concept of the Environmental Management Plan (EMP) has become an important aspect in all Project activities due to the growing awareness of the potential damage that unchecked development can cause on the natural environment. The implementation of the EMP aims to strike a balance between the need for conservation and protection of natural resources and that of meeting the needs of the society. There are various strategies that could be adopted in the development of the EMP for the proposed Project. An environmental monitoring and auditing program is outlined so that any potential impacts from Project can be reduced to acceptable levels.

Continuous implementation of an environmental monitoring and auditing program is recommended so that the effectiveness of mitigation measures can be assessed and improved if necessary. In addition, such a program can provide an early indication on the effectiveness of the recommended mitigating measures to achieve compliance with relevant acceptable standards and approval conditions.

Upon the approval of the preliminary EIA and the Project, the EMP will be formulated to incorporate the Conditions of Approval as stipulated in the approval letter from the DOE and the mitigating measures suggested in this report. The EMP can effectively address any adverse environmental impacts during the construction stage of the Project. Impact minimisation can be achieved via proper management of construction activities or by adopting an ISO 14000 Environmental Management System (EMS) in the overall environmental planning.

ISO 14000 (EMS) is designed to provide guidelines for the best environmental management practices. EMS enables organisations to meet the growing environmental performance expectations and to comply with national and/or international requirements. The requirements of an EMS are summarised in Table 8.1.

A comprehensive EMP which is part of an overall EMS, should be supported by allocation of institution/administrative responsibilities, responsibility of executing mitigation measures, adequate budget for EMP implementation and a qualified team of personnel for effective planning, implementation, reporting and evaluation. The programs described in the following sections covers:

 Guidelines for Project design and planning  Guidelines for Project implementation/renovation  Guidelines for Project operation and maintenance  Environmental monitoring and auditing program

8.6 ENVIRONMENTAL MONITORING PROGRAM

The objectives of the post EIA environmental monitoring program are:

 assess both the short and long term environmental effects associated with the prescribed activity;  verify the environmental impact predicted in the EIA report;  provide an early indication of adverse environmental impact; and  detect changes in impact trends.

Prior to the commencement of the construction phase, environmental monitoring is necessary to provide a baseline of the existing environmental parameters. Subsequent monitoring will thus provide an early indication of any adverse environmental impact so that the construction activities can be carried out in an environmentally responsible manner.

With such early indications, appropriate remedial actions can be carried out to prevent unacceptable impacts or any further deterioration of the environment. A regular monitoring program for water, air and noise should be carried out to enable meaningful execution of periodic environmental auditing. In the EIA context, auditing can be defined

Environment Asia Sdn Bhd 8-6 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

as a systematic, documented, periodic and objective review conducted to meet environmental requirements.

8.6.1 Water Quality Monitoring

Construction Phase

Water quality monitoring shall be necessary during the construction stage to access the impacts of Project activities onto the existing water bodies. Surface runoff from the Project site will be diverted into the temporary drains which flow into the sediment basins prior to discharging into the waterways / rivers. Thus, monitoring at the discharge point of the sediment basin is proposed to be carried out.

In addition to the above, the northern Project site is drained by Sg. Kedondong and Sg. Payong. Sg. Payong is a seasonal natural waterway which flows to JPS retention pond located in the southern development under MBPJ prior flowing to Sg. Damansara. Thus, water samples shall be collected from five locations, i.e., from Sg. Kedondong (2 upstream and 1 downstream) and upstream and downstream of Sg. Payong. The locations of the sampling stations are shown in Figure 8.1.

The full range of parameters to be monitored during construction phase is listed in Table 8.6. The sampling and analysis should be carried out by a SAMM accredited laboratory on a monthly basis, while reporting to the Department of Environment is to be made on a quarterly basis.

Operational Phase

During the operational phase, no wastewater effluent will be generated. Therefore, no water monitoring is required.

8.6.2 Air Quality Monitoring

Construction Phase

During the construction stage, the main emissions into the air would be fugitive dust/particulate. A regular monitoring program is needed to verify that primary pollutant levels in the ambient air are below the allowable limit of the Recommended Malaysian Air Quality Guidelines. The monitoring of air quality is recommended to be carried out on a quarterly basis upon commencement of the site activities. Two locations are proposed for air monitoring at the proposed Project site and another one at the nearest sensitive receptor (Section 8 Kota Damansara) (refer Figure 8.1). The parameter to be monitored as well as the allowable limit is shown in Table 8.6.

Operational Phase

Routine air monitoring during the operational phase is not deemed necessary as no significant air pollution is expected.

Environment Asia Sdn Bhd 8-7 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

8.6.3 Noise Level Monitoring

Construction Phase

Noise impact is not deemed significant for the proposed Project. The monitoring for noise level is recommended to be conducted quarterly. Two locations similar with the air monitoring points are chosen for the noise monitoring as shown in Figure 8.1. The noise levels are to be recorded continuously for a period of 8 hours and should comply with the DOE’s Recommended Noise Exposure Limit. The location and parameters to be monitored are listed in Table 8.6.

Operational Phase

During the operational phase, noise monitoring will not be required as no excessive noise pollution will be generated.

8.7 ENVIRONMENTAL SITE AUDIT

Environmental site audit is recommended to be carried out on a quarterly basis during the construction phase. The main objectives of the audit are to identify any non-compliance with the requirements of the EIA/EMP and practices that could be contributing towards the deterioration of noise, air and water quality. The site audit shall be carried out in accordance with accepted protocol detailing areas of non-compliance. Any specific instances of non compliance with legislative standards and the probable cause of such non-compliance shall be identified.

8.8 HEALTH AND SAFETY

A written site-specific health and safety plan should be prepared prior to the commencement of any site activities. The plan shall be made for review and should cover the following:

 Storage of construction materials or fuels/lubricants utilised by the machinery.  Safety practises to be adhered by workers as well as drivers of vehicles using public roads.

8.9 EVENT CONTINGENCY PLAN

An event contingency plan (ECP) comprises procedures to be adopted when any pollution occur either accidentally or through inadequate implementation of mitigation measures. The corrective actions that are required depend on the level of pollution measured in the monitoring programme. There are three levels specified by DOE, i.e. trigger limit, action limit and target limit (Environmental Impact Assessment Guidelines for Industrial Project, 1995).

The levels are defined as follows:

Environment Asia Sdn Bhd 8-8 Preliminary Environmental Impact Assessment New Township at Sungai Buloh (RRIM) - MBSA

 Trigger levels – beyond which is an indication of a deteriorating ambient environment for which a typical response could be more frequent monitoring.

 Action limits – beyond which appropriate remedial action may be necessary to prevent environmental quality from going beyond the target limits, which would be unacceptable.

 Target limits – statutory limits stipulated under the EQA (1974), EIA guidelines, DOE recommended limits or generally accepted voluntary limits. If these are exceeded, works or operation should not proceed without appropriate remedial action, including a critical review of plant and working methods.

The procedures are orientated to minimize the impacts of various events such as fire, landslide, erosion and petroleum spillage, etc. on the site, personnel involved, the public and the environment. The ECP also assigns responsibilities to appropriate personnel for its implementation. The ECPs should be incorporated in the EMP Report.

CHAPTER 9: RESIDUAL IMPACTS

Residual impacts are potential impacts that may remain after completion of the northern Project site and in spite of mitigation measures being adopted and implemented. These impacts are considered to be long-term and irreversible which occur as a consequence of the development. Generally, the scale and nature of the Project will determine whether any residual impacts will occur and the intensity of these impacts.

As the proposed Project only involves master infrastructure facilities, there will be no significant residual impacts.

9.1 AIR QUALITY

The Project will not generate any adverse residual air quality impacts. During the operational phase when the residential and commercial units are occupied, a slight decrease in air quality is possible due to the increase in the traffic.

9.2 NOISE QUALITY

An increase in noise levels is expected from the operation period of the Project in tandem with the increase in traffic activities. The increase in noise levels will mostly be centered at the main roads leading in and out of the Project site but the residual impact is not significant.

9.3 WATER QUALITY

No residual impact from the change in surface run-off is expected as the proposed detention ponds will accommodate any increased flow from the Project site.

9.4 SOCIO-ECONOMY

Generally, the Project is expected to generate positive residual impacts to the local community in the form of providing quality housing and job opportunities which will contribute to local economy growth.

9.5 TRAFFIC

When fully completed, the proposed Project site is expected to result in an increase in traffic movement using the existing roads. However the upgraded junctions and Jalan Sg. Buloh as well as the spine road will function as a dispersal access to major area.
