Introduction

The Water Management Plan covers water extraction for industrial and domestic uses

and wastewater discharges. The plan has been developed in compliance to the

regulatory requirements of Environment (Amended) Act 2014 and the provisions of

RSPO – Principal 4.4.1 on Water Quality, Surface and Ground Water Management

action.

The primary purpose of the Water Management Plan is to ensure best practices are in

place to maintain water quality and long term availability of surface and ground water

and ensure water extraction and waste water discharges are within the regulatory

standards and the impacts are monitored and relevant corrective actions are

undertaken. The plan includes water extraction, water quality monitoring, water quality

criteria and wastewater monitoring program. .

2.0 Objectives

The objective of the Water Management Plan is to;

Control the quality and quantity of water so that it is sustainably safe for use now

and available in the future.

Ensure that this objective is achieved; HOP will carry out its operations within the

relevant regulatory requirements and mechanisms so that the water resources

are of quality standard and are available for use for now and in the future.

Water Extraction

The following sections are covered under water extraction

1.0 Legal Requirement - Water Extraction

2.0 Water extraction for Domestic uses





04





3.0 Domestic water tank cleaning procedure

4.0 Domestic water supply criteria

5.0 Water extraction for Nursery uses

6.0 Water extraction for Mill uses

3.1 Legal Requirement

HOP has been issued with conditional Environment Permit (Water Extraction) for water

use as required by the provisions of the Environment (Amended) Act 2014 and its

relevant regulations (Environment regulations list). The conditional environment permit

(water extraction) is specified in the permits issued to HOP (refer to HOP List of

Environment Permits attached). The conditional environment permit for water extraction

requires HOP to comply with the following conditions. HOP among other provisions

shall;

1.0 ensure that its water well is permanently cased to prevent contamination of the ground

water aquifer by surface water runoff.

2.0 ensure that the volume of water extracted is monitored and a report to be

submitted to the Managing Director of CEPA at the end of each calendar year,

3.0 ensure that there are good irrigation practices to minimize rainfall run off ( if any)

which may contain fertilizer and /or pesticides

4.0 ensure that the quality of its bore water complies with the Public Health (Drinking)

water quality criteria as outlined in Table 18 of this plan

5.0 Conduct monthly water quality monitoring with respect to parameters specified in

table 18 of this plan. Results generated from the water quality monitoring program

shall be submitted to the Managing Director of CEPA annually, at the end of

December of each calendar year when reporting on the annual environmental

performance of HOP. A copy of the monitoring data should also be provided to

relevant authorities upon request.

6.0 Ensure that any significant increase in the volume of abstraction as specified by the

environment permit for the extraction of water shall require an amendment application to





04





be submitted to the Managing Director of CEPA for approval prior to increase volume of

extraction
