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 JKR Tender 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.

INTRODUCTION

Introduction

Environmental protection and conservation is gaining more significance in the long term national 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 of document 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 nation‟s aspirations in protecting the environment, JKR has formulated and implemented the “JKR Green Mission” and has an Accredited MS ISO 14001 since 5th November 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 document and subsequently implemented during the planning, construction and operational 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 JKR‟s 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 been introduced 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 2004 and 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) (b) (c) (d) (e) (f) (g) (h) (i) (j) (k)

National Land Code (Act 56 of 1965) Town and Country Planning Act 1976, (Act 172) Street, Drainage and Building Act, 1974: Act 133 and Amendment, 1978 Protection of Wildlife Act, 1972 (Act 76) Forestry Act 1984 (Act 313) Land Conservation Act 1960 (Act 385) Occupational Safety and Health Act 1994 (Act 514) Solid Waste and Public Cleansing Management Act 2007 (Act 672) Federal Territory (Planning) Act 1982 (Act 267) Workers Minimum Amenities Act 1990 (Act 446) Local Government Act 1976 (Act 171)

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)(Environmental Impact 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) categories of 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 wastes and 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 activities are contained in First Schedule and Second Schedule of 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 Project‟s compliance with the general requirements of the Client‟s 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/or other 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 document that 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 responsibilities of the various parties involved in the Project, the environmental requirements for the Project and specifies mitigation measures and environmental 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;

12

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 construction stage in order to ensure that the operational stage of the project does not cause any environmental damage. The impact of generated 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 Guidelines in 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:Area to be developed
