ACID SULFATE MANAGEMENT PLAN
FOR A PROPOSED DEVELOPMENT AT
51 WITTA CIRCLE, NOOSA HEADS

1. INTRODUCTION

Bio-Track Pty Ltd has been commissioned by Middap Ditchfield Pty Ltd to prepare an acid sulfate soil
management plan (ASSMP) for a proposed development at 51 Witta Circle, Noosa Heads. This study
is based upon soil chemical analysis data, site drawings and bore log information.

2. Response to Request For Information

Bore Hole Location
The geotechnical engineers (Geoinvestigations Pty Ltd) have supplied a drawing showing the
location of the test bore hole locations. This is attached as Figure 1.

Groundwater
The architects (Middap Ditchfield Pty td) have used the groundwater levels observed by the
geotechnical engineers, the bore hole focations and proposed design to prepare a drawing
showing a section with groundwater levels, footings and the swimming poo! (proposed). This
drawing is shown as Figure 2. (Red arrows have been attached to highlight the groundwater
level.)

The architects have advised the following conditions apply to the proposed development:

all proposed excavation will be above the watertable
* no structures or services will be constructed below the watertable
* there will be no requirement for dewatering

The implications are:

there will be no discharge of groundwater to the local environment
. there will be no noise associated with dewatering
* there will be no need to monitor groundwater or groundwater discharges

Ponded Water .
The soil profile descriptions indicate the soils are deep sands. Ponded water and runoff or
ponded water is not expected. The need to monitor and regulate the quality of ponded water is
not expected.

Corrective Measures
In the event of non-compliance with any aspect of the ASSMP the following measures will be
implemented:
* measurements will be repeated immediately to confirm non-compliance
construction activity will cease if non-compliant conditions are demonstrated
corrective action will be taken within one working day
in the event of corrective action failing to return the environmental conditions
to a state of compliance following action will be undertaken:

*
*
*

the local authority will be notified within one working day

a suitably qualified person will be engaged to study the nature of the
problem within one working day

the local authority will be informed on a daily basis of field conditions
ang corrective action until such time as compliant conditions are
achieved.

a record will maintained of field conditions and corrective actions
