CHAPTER TERMS OF REFERENCE (TOR) OF 2 THE EIA STUDY
2.0 INTRODUCTION
The Terms of Reference (TOR) for the preparation of the Environmental Impact Assessment (EIA) Study for the “Proposed Pan-Island Link 1 Highway Project, Penang” was prepared and submitted to the Department of Environment (DOE) Penang on 11 March 2016. It was endorsed by the DOE Putrajaya via a letter Ref. AS(PN)50/013/500/047 Jld. 2 ( ) dated 22 November 2016 as shown in Appendix 2. The validity period for the TOR was for one (1) year starting 22 November 2016.
Subsequently, a letter requesting for an extension to the TOR validity period was submitted to DOE Putrajaya on 16 November 2017. An extension of 3 months was sought because extra time was needed to finalize the alignment for the PIL1 Highway at the Bukit Bendera section in Penang Hills (to avoid sensitive areas) and also to obtain JPS approval of the PIL1 Highway alignment along Sg. Ara and Sg. Kluang leading to the LCE Interchange in Bayan Lepas (Appendix 2).
The contents of the TOR and the DOE TOR Approval Conditions are summarized below.

2.3 SCOPE OF PROJECT
The proposed PIL1 Highway Project comprise a new highway that will be built to link the Gurney Drive area in the northern part of Penang Island and through the Penang Hills to Bayan Lepas in the south. This new highway will provide an alternative north-south road link in addition to the existing Tun Dr. Lim Chong Eu (LCE) Expressway.
The PIL1 Highway consists of several components as follows:
i. Elevated road sections (viaducts), ii. Tunnel sections, and iii. An embankment road section.
The total length of the highway is 19.5 km. It shall start at the Gurney Drive area within the reclaimed area of Seri Tanjung Pinang Phase 2 in the northern part of Penang Island and end in Bayan Lepas at the Tun Dr. Lim Chong Eu Expressway in the south.
The viaduct sections of the proposed PIL1 Highway shall traverse heavily built-up urban areas in the northern and mid-southern segments and also along river reserves in the southern part. The tunnel sections will cut through the Penang Hills in the middle part of the proposed new Highway.
Therefore the proposed activity falls under “Prescribed Activity 20(c) First Schedule: “Construction of road, tunnel or bridge traversing or adjacent or near to environmentally sensitive areas” and “Prescribed Activity 13(b) Second Schedule: “Construction of road, tunnel or bridge traversing an area with slope greater than or equal to 350” of Subparagraph 3(1) and (4) of the Environmental Quality (Prescribed Activities) (Environmental Impact Assessment) Order, 2015. Hence the proposed PIL1 Project falls under the Second Schedule of the Environmental Quality (Prescribed Activities) (Environmental Impact Assessment) Order, 2015.

2.4 PROJECT ALTERNATIVES AND ENVIRONMENTAL IMPACTS
The principal objective of the proposed PIL1 Highway project is to provide an alternative north-south highway link in addition to the existing Tun Dr. Lim Chong Eu (LCE) Expressway. This is because the LCE, being the sole pragmatic/sensible route for north-south bound traffic (Georgetown - Bayan Lepas and Penang International Airport), is heavily congested with traffic daily, especially during peak hours. The proposed new highway is anticipated to effectively reduce travelling time as well as related transportation costs between these two areas since it will by-pass the LCE and other frequently congested local roads in the city area. PIL1 will be a non-tolled Highway.
The whole highway corridor (19.2 km) traverses across flat and slightly undulating terrain as well as hilly mountainous areas. In order to minimize adverse environmental and social impacts, the elevated highway or viaduct design will be adopted over much of the highway length (9.7 km or 50.52%) which cuts across flat and slightly undulating terrain. These areas are also densely populated areas. Only 1.7 km (8.85%) of embankment roads will be constructed close to the hilly areas. The hilly mountainous areas will be traversed by tunnels (7.8 km or 40.63%).
The existing land use in the proposed new highway corridor contains heavily built-up and populated urban areas with many amenities (such as schools, temples, shrines, residential and business premises, eateries, high rise buildings, utility services, etc.). The proposed alignment also passes near or cuts through hilly areas (parkland, Penang Funicular Rail at Bukit Bendera, Kok Lek Si Temple, Air Itam Dam, small shrines, low rise and high rise buildings, etc.) and along sensitive river reserves (holding squatter houses, fishermen boat mooring areas and tour boat operator stores). The local roads in the vicinity of the proposed new highway corridor invariably have high daily traffic flows.
Therefore, the anticipated environmental impacts shall be related to social issues (e.g. land/property acquisition, relocation/resettlement, places of worship, squatter houses, plight of fishermen and tour boat operators, environmental annoyance – noise, vibration, dust, traffic congestion, public safety) and environmentally related issues – noise, vibration, air pollution, water pollution, traffic congestion, safety, and flash floods.
Consequently, the project’s alternatives shall be examined to select the best option/alternative to reduce/minimize any adverse social and environmental impacts. The alternatives examined shall be in terms of the following:
a. Proposed highway alignment option. b. Viaduct vs At-Grade road option. c. Tunnelling methods.

8 TunDr. Lim Chong Eu Interchange
The alignment (viaduct) runs along the river reserve of Sg. Kluang until it meets the Tun LCE Interchange.
Examination of the information in Figure 2.4.1 and Table 2.4.1 coupled with the primary land use survey information carried out in the study area indicates potential encumbrances along the proposed alignment with respect to land/property acquisition, public safety, environmental nuisance, removal and resettlement of squatters and relocation of fishermen boat mooring sites and tour boat operator storage sheds. The potential encumbrances in the Penang Hill section relate to earth disturbance, potential soil erosion and earth movements, and the subsequent impacts on water quality, noise and vibration, air pollution, traffic congestion and safety issues to residents living near the project corridor.
Therefore, alternative alignments shall be examined that would avert or minimize the potential adverse impacts.

b. Viaduct vs at-Grade Road
This option shall examine the pros and cons of adopting the highway design using the At- Grade road or the elevated road (viaduct) approach against the potential impacts. The comparison shall take into account the land use and physical characteristics of the roads in the study area, junctions (signalised or un-signalized), turn-ins and turn-outs and the adjacent developments along the roadsides. The factors that will be considered shall include road speed and the LOS at specific locations (if available). Other factors that shall be considered will include:
the availability of land constructability land acquisition construction costs social impacts c. Tunneling Method
Various tunnelling methods will be explored for tunnel construction.
Selection of tunnelling method depends on multiple factors, for example, the type of rock, the bore size, accessibility condition and geological condition. These multiples factors will influence economic of each tunnelling method and speed of the tunnelling works.
It is important that the correct tunnelling method is selected so that it can be constructed in the most efficient and safe manner.
For the PIL1 Project, the prospective tunnelling method that will be considered includes:
Drill & Blast method - Full face method - Heading and bench method - Drift method - Pilot tunnel method
Hard TBM method Cut-Cover method Immersed tube method
2 - 13
THE PROPOSED PAN ISLAND LINK 1 HIGHWAY PROJECT, PENANG
The pros and cons of some of the tunneling methods mentioned above shall be considered taking into consideration the geological and soil conditions in the study area. The selection shall be based on technical and costs considerations. d. No Project Option
The No Project option will cause major road transport issues on Penang Island in the long run as summarized in the Penang Transport Master Plan (PTMP). Rapid urban development coupled with strong economic growth will place greater demands on the road transportation system in the future. Efficient road systems provide economic and social opportunities and benefits that results in positive multiplier effects such as better accessibility to markets, employment and additional investments. When road systems are deficient in terms of capacity or reliability, they can have an economic costs such as reduced or missed opportunities and lower quality of life.
2.5 SIGNIFICANT ENVIRONMENTAL IMPACTS TO BE STUDIED
For the purpose of describing the environmental impacts that can be associated with the PIL1 Project development, the whole alignment shall be divided into three (3) sections as shown in Figure 2.5.1. The division is based on topographical and land use features in the proposed Project alignment. The 3 sections are as follows:
Section A covers the length from the Gurney roundabout to the north portal of the first tunnel. This stretch comprise flat to slightly rolling terrain and consists of densely developed and populated areas.
Section B covers the length from the first tunnel to the south portal of Tunnel 4 at Sg. Ara. This stretch consists of undulating to hilly areas and is less densely developed with sizeable tracts of forest and scrubland areas. The proposed alignment passes through Penang Hill and skirts around the heavily populated and developed areas in Paya Terubong, Air Hitam and Relau.
Section C covers the length from the south portal of Tunnel 4 to the LCE Expressway. This stretch consists of slightly rolling to flat terrain and is densely developed and populated. A specific description of the potential impacts according to the major project components and project construction activities is presented in Table 2.5.1.
