PREFACE

In line with the MS: ISO 14001 requirement, a continual improvement of the system must

be done to ensure success and effectiveness of environmentally sustainable approach in

construction. To produce a clear and comprehensive tender document, revision of JKRTender Documents on environment protection and enhancements has been done by

itemising the environmental works into the Bill of Quantities to allow contractors to tender

a realistic price. Arahan Teknik (Jalan) 16/03, produced in 2004, provided changes to the

items in the Tender Document with regards to the Condition of Contracts, Instruction to

Tenderers, Specification to Environmental Protection and Enhancements, Preamble to Bill

of Quantities, Need Statement, Bill of Quantities and Drawings.

In 2006, a committee comprising multi-disciplinary personnel was set up to revise the

Arahan Teknik (Jalan) 16/03. Changes have been made in accordance to problems

encountered and inadequacies of the previous Arahan Teknik. The overall improvement is

aimed to ensure contractors understand the application of the environment protection

works that they have tendered in the Bill of Quantities. Notwithstanding the importance of

other technical agencies requirements to protect the environment, some parts have been

added such as the preparation of Erosion and Sediment Control Plan (ESCP) and

management of disposal site for surplus material as part of the latest EIA requirements.

Drawings of mitigation works have been revised and amended. The revised Arahan

Teknik (Jalan) 16/03 is made applicable, not only to road projects, but to all projects in

JKR. It is important that all parties involved in the construction industry, be made aware of

the latest government requirements in environment protection to ensure our nation has the

capacity to be sustainable in the long term future.

CHAPTER 1.0: INTRODUCTION

1.0 Introduction

Environmental protection and conservation is gaining more significance in the long termnational development plan. In this regards, Malaysia as a country, has reaffirmed its

commitments towards the protection and conservation of its environment as stated in the

National Policy on Environment, National Physical Plan (NPP) and prevailing

Malaysia Plans.

In summary, the National Policy on Environment aims for continuous economic, social

and cultural progress and enhancement of the quality of life of Malaysians, through

environmentally sound and sustainable development.

The main goal of the NPP is to create an efficient, equitable and sustainable national

framework that will guide future development of the country. It is an important piece ofdocument as it provides the spatial element in development planning as well as spells out

policies that determine the direction of physical development and conservation areas

within Peninsular Malaysia. It also identifies areas that need to be conserved and protected

via a ranking system. These areas are called Environmentally Sensitive Areas (ESA).

Such identification will greatly assist any project proponent (government or private sector)

in evaluating and determining the feasibility of some projects at macro or national level.

In line with the nations aspirations in protecting the environment, JKR has formulated

and implemented the JKR Green Mission and has an Accredited MS ISO 14001

since 5thNovember 2002. The main objective of the document is to protect and enhance

the environment by ensuring that projects are being implemented in a sustainable manner

and with the least impacts to the environment.

1.1 Objectives

This Revised Arahan Teknik shall aim to attain the following objectives:-

To ensure that the JKR EMS ISO 14001 requirements in terms of environmental

protection measures are properly incorporated in the preparation of the tender

documentand subsequently implementedduring the planning, construction andoperational stages of the project.

To guide users on the requirements pertaining to environmental protection,mitigation and enhancement measures in the preparation of tender document.

1.2 Method of Procurement

This document is applicable for both conventional and design and build contracts. A

typical example of the process flow for both types of contracts can be referred to in the

JKRs Quality Management System (QMS).

involve reclamation;

Marine-related projects such as jetties, marina, coastal protection structures or any

structure that extends out into the sea; and

Projects located within areas identified as Environmentally Sensitive Areas (ESAs)such as wildlife sanctuary, wetlands, marine parks and national parks.

For projects identified above, more specific environmental protection measures may be

required in order to minimize impacts to the environment.

1.4 Format of Document

This Revised Arahan Teknik (Jalan) 16/03 has been divided into eight chapters addressing

the various components which form part and parcel of the tender document preparation

process.

In addition to the introductory material in this section, the document contains:-

CHAPTER 2: ENVIRONMENTAL REQUIREMENTS

The legislation that is related to the prevention, abatement, control of pollution and

enhancement of the environment in Malaysia is stipulated in the Environmental Quality

Act 1974 (Amendment) 2007. To date, 40 sets of Regulations and Orders have beenintroduced and enforced. Under this Act, an Environmental Impact Assessment (EIA) is

required for activities prescribed under the Environmental Quality (Prescribed

Activities (Environmental Impact Assessment) Order 1987. Those activities that are

not subject to the mandatory EIA requirement are nevertheless subject to various other

regulations under the Act. The standard regulations require evaluation for project siting,

pollution control, monitoring and self regulation via the audit process.

For the states of Sabah and Sarawak, the environmental requirements are clearly stipulated

in the Environment Protection (Amendment) Enactment 2004and Natural Resources

and Environment Ordinance respectively.

Apart from compliance with the Environmental Quality Act (EQA) 1974 (Act 127) and

other related environmental legislations, the following Acts are also applicable based on

its relevancy to the planning, design, construction, equipping and commissioning of any

project.

(a)

National Land Code (Act 56 of 1965)

(b) Town and Country Planning Act 1976, (Act 172)

(c)

Street, Drainage and Building Act, 1974: Act 133 and Amendment, 1978

(d) Protection of Wildlife Act, 1972 (Act 76)

(e) Forestry Act 1984 (Act 313)

(f)

Land Conservation Act 1960 (Act 385)

(g) Occupational Safety and Health Act 1994 (Act 514)

(h) Solid Waste and Public Cleansing Management Act 2007 (Act 672)

2.1 Planning/Design Stage

Environmental requirement during planning or design stage is clear whereby if the said

project has been classified as a prescribed activity according to the Environmental

Quality (Prescribed Activities) (Environmental Impact Assessment) Order 1987 and

Section 34A of the Environmental Quality (Prescribed Activities)(EnvironmentalImpact Assessment) Order 1987, an Environmental Impact Assessment (EIA) study

needs to be carried out and submitted to Department of Environment for approval prior to

project implementation.

Under the Act, there are a total of nineteen (19) categoriesof prescribed activities which

include agriculture, airport, drainage and irrigation, land reclamation, fisheries, forestry,

housing, industry, railways, transportation, resort and recreation development, waste

treatment and disposal, and water supply projects. Additionally, a Detailed Environmental

Impact Assessment (DEIA) study is required for thirteen (13)different types of projects

which include steel mill, pulp and paper mill, cement plant, coal-fired power plant, dams

(hydroelectric and water supply), coastal land reclamation, incinerators (scheduled wastesand solid wastes, solid wastes disposal sites, projects involving land clearance where more

than 50% of the area has slope>250) and logging (>500 hectares). It is to be noted that for

projects in Sabah and Sarawak, specific local legislations pertaining to EIA requirements

need to be adhered to.

For the state of Sabah, lists of prescribed activitiesare contained in First Scheduleand

Second Scheduleof the Environment Protection (Prescribed Activities) (Environment

Impact Assessment) Order 2005. For projects in Sabah, an environmental impact

assessment report is required for any prescribed activities specified in the Second

Schedule of the Environment Protection (Prescribed Activities) (Environment Impact

Assessment) Order 2005. In addition, a proposal for mitigation measures is required for

any prescribed activities specified in the First Schedule.

For projects in Sarawak, an environmental impact assessment report is required for any

prescribed activities specified in the First Schedule of the Natural Resources and

Environment (Prescribed Activities) Order 1994.

Apart from the legislative requirement, EIA may be prepared taking into consideration the

sensitivity of the project in terms of its location, site conditions and magnitude of impacts.

In some cases, preparation of EIA study is required by the local authorities or form part of

the contractual requirement of a project.

Findings from the study are intended to provide input in the planning of the Project,

particularly in minimizing environmental impacts during the construction and operational

stages. An EIA is considered as a planning tool to assist the Project Initiator in

anticipating impacts of the development, both beneficial and adverse, with an aim to

maximize the beneficial impacts and minimize the adverse impacts on the environment.

For better understanding of the EIA process and procedures, an EIA flow chart for both

Preliminary EIA and Detailed EIA are shown in Figures 1 and 2. Similarly, a simple EIA

flow chart for Sarawak and Sabah are shown in Figures 3 and 4.

2.2 Implementation/ Construction Stage

In order to monitor Projects compliance with the general requirements of the Clients

needs and relevant environmental legislation, an Environmental Management Plan

(EMP)shall be prepared as detailed herein. The EMP shall be prepared in accordance to

the format or guidelines recommended by the Department of Environment (DOE) and/orother relevant government departments requirements. These guidelines shall provide the

framework for the preparation of the environmental management and mitigation measures

to mitigate on-site impacts to acceptable limits as stipulated by the DOE.

The EMP is not intended as a rigid planning document but an active documentthat shall

be revised and improved, as and when required, throughout the implementation stage.

Proper execution of the EMP is expected to result in minimal adverse impacts on the

surrounding environment and its natural resources.

The plan shall outline the responsibilitiesof the various parties involved in the Project,

the environmentalrequirements for the Project and specifies mitigationmeasures andenvironmental monitoring and audit that must be implemented during construction

stage. The EMP shall be prepared and implemented to ensure compliance to the JKR EMS

ISO 14001.

Integral to EMP is the establishment of a monitoring program that serves as a

quantitative feedback mechanism on the effectiveness of the mitigation measures.

Essentially, the monitoring program is a set of procedures targeted towards periodical

measurement of environmental indicators that provides a platform to evaluate

environmental performance through comparisons against baseline and compliance levels.

Selection of environmental components to monitor, their locations, parameters and

frequency of monitoring are governed by the EIA approval conditions or by a Registered

Environmental Consultant (if no EIA was carried out for the project). As a norm,

monitoring is centered on the issues of water, noise and air qualities likely to be impacted

upon by the Project.

The auditing procedure and schedule shall be detailed out in the EMP. The audit shall

focus on the implementation of the EMP and/or other environmental management

elements. The environmental auditor shall have the necessary expertise and experience to

execute the tasks diligently and professionally in accordance with the requirements of JKR

EMS: MS ISO 14001 and shall undertake the following tasks:-

(a) To carry out environmental compliance audits quarterly and closure audit on

completion of the project;

(b) To evaluate monitoring data for water, air, noise qualities and if applicable

vibration qualities;

(c)

To verify implementation of corrective and preventive action findings on adequacy

of compliance to the EMP and/or JKR EMS ISO 14001;

(d) To prepare a comprehensive environmental auditing report in compliance to

elements as stated in the EMP and/or JKR EMS ISO 14001;


19/136

13

2.3 Operational/Post Construction Stage

Upon submission and acceptance of the closing audit at the end of the construction period,

monitoring of operational activities in compliance to the necessary laws and regulations is

encouraged to be continued during the post constructionstage in order to ensure that the

operational stage of the project does not cause any environmental damage. The impact ofgenerated wastewater has been deemed to be the more significant residual impact that

requires further monitoring. The quality of any wastewater discharged must comply with

the limits as stipulated by the Environmental Quality (Sewage) Regulations 2009.

2.4 Applicable Guidelines

The use of the relevant Guidelinesin the planning/design stage of the project is deemed

necessary in order to ensure the project activities do not violate any applicable laws and

regulations. The guidelines need to be used in respect to the project site specific

conditions.

The General guidelines applicable are as follows:-
