1) Introduction

Cooroy Mountain Springwater Pty Ltd
commissioned Gilbert & Sutherland Pty Ltd
(G&S) to prepare a Conceptual Effluent
Treatment and Disposal Strategy for Lot 2
SP143409, 314 Cooroy Mountain Road,
Cooroy Queensland (‘the site’). The site
occupies a total area of 48.17 hectares and
is shown on Drawing HJ0085.1.1.

An Effluent Disposal Report was previously
prepared for the site by Global Testing Pty
Ltd in 2007'.

This current assessment constitutes a
revision of the site effluent treatment and
disposal strategy in accordance with AS/NZS
1547:2000 ‘On-site domestic wastewater
management’ and the experts agreement
dated 2 September 2009.

The issues raised in the Report of Experts
Meeting September 2, 2009 relevant to this
conceptual assessment are reproduced
below.

° An updated effluent treatment and
disposal strategy (ET&DS) is
required for the project, to
demonstrate that adequate
treatment of wastewater from
plant and wash down, and from
staff and suitable on site disposal,

taking account of current plant
staffing and waste generation
figures. A conceptual ET&DS
should be completed by G&S to
support the current application, to
outline EP's to be treated,
treatment process, and disposal
areas and locations. This work
should include suitable sampling
and testing of the current waste
stream discharge, appropriate to
the relevant sources.

A further investigation of actual
EP's being generated by the
combination of plant, wash down
and staff wastewater is to be
carried out by G&S to support the
current application, and to assess if
additional ERA licensing is required
for the site.

In performing this assessment site physical
characteristics and soil suitability have been
reviewed.
