WATER SERVICES INDUSTRY ACT 2006

GUIDE FOR DETERMINING THE NEED FOR AN EIA

Developments of certain criteria will require an EIA study that covers its sewerage works

proposals. The EIA must be submitted and approved by the Department of Environment

(DOE) prior to detail sewerage works planning approval. However, regardless of the type and

size of a development, all sewerage works will need to submit a complete Environmental

Criteria Evaluation form.

Development EIA As per the Environmental Quality Order (Prescribed Activities) (Environmental Impact Assessment),

1988, Schedule 7, for a development that covers an area of 50 hectares or greater, the developer must

obtain an EIA approval for the entire project. A section of the assessment must cover the sewerage

aspects of the development, which includes the network system, sewage treatment plants, and/or

sludge treatment facilities. The EIA must address land area requirements for the STP and ensure

sufficient buffer to minimize impact onto its surrounding developments. Buffer requirements as

stipulated in this guideline must be addressed.

Preliminary EIA All STPs constructed by government or its appointed agents, and STPs constructed by developers

which are given permanent status and to be handed over as regional public STPs would require a

separate preliminary EIA approval from DOE.

Environmental Criteria Evaluation The purpose of this criteria checklist is to ensure that the environmental impacts associated with the

plant are minimized when the plant becomes operational. The evaluation includes issues on siting the

plant, water quality and design with environmental considerations.

Procedure for EIA Approval for Development EIAs shall be prepared according to the DOE’s guidelines and requirements covering all aspects of

sewerage works which includes network, sewage treatment plant and/or sludge treatment facilities,

where applicable.

The Commission shall be informed of any submissions to the DOE and a copy must be attached with

other application documents. The same shall be done once the EIA approval is received from the

DOE, highlighting the approval conditions. This is necessary, as EIA approval is part of the

Commission sewerage works approval procedure.

Note: All developments which do not fit the above development criteria are exempted from EIA

requirements.

Appendix B Report Format for HAZOP Study and Checklist

GUIDE TO CARRY OUT HAZOP STUDY AND FORMAT FOR HAZOP REPORT ≥ 20,000 PE.

The methods presented here are not intended to be prescriptive and a certain amount of flexibility will

be required to apply these techniques to different types of projects with different contract strategies.

1.0 HAZOP Study

HAZOP study is a procedural tools designed to identify the safety and operability deficiencies in the

design of a treatment facility.

Once a potential cause has been identified in the HAZOP study, the HAZOP study team will identify

the potential consequences. If the cause is feasible, and the consequences severe enough, a member

of the study team may have to investigate the potential means of eliminating or reducing the problem.

“Fact finding” actions may also be raised if sufficient information is not available at the meeting to

discuss causes and consequences.

2.0 HAZOP Study Team Members

HAZOP Study ideally should have team members of multi-disciplines involved in the design and

operation of the plants. Team members must have a detailed knowledge of the design intentions

and/or intended operation of the plant. The team must contain people with sufficient knowledge and

experience to identify and understand the consequences and importance of deviation or deficiencies

pertaining to design of the plants.

3.0 Format of HAZOP Report

Upon ultimate completion of a HAZOP, i.e. once all actions have been satisfactorily resolved, a

HAZOP report will be produced and the report should consist but not limited to the followings:

1. Executive Summary

2. HAZOP Signoff Sheet

3. Introduction and Objective

4. HAZOP Methodology and Techniques

5. HAZOP Team, Attendance and Meeting Agenda

6. The minutes of the HAZOP Study conducted comprising issues raised and action or

safeguard taken to resolve the issues, significance of issues raised, amended detailed

drawings to suit the HAZOP requirements and signing off of actions by the

responsible party

7. Summary of findings and outcome of the Study

8. Conclusion
