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).

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.

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;

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.
