4.6 Catchment Management
[Project Approval Schedule 4 conditions 1 and 2]
4.6.1 Catchment Monitoring Program
[Project Approval Schedule 4 condition 2]
The Catchment Monitoring Program prepared to satisfy Project Approval Schedule 4 condition 2 was
submitted to the Director-General for endorsement on 14 April 2010. The Catchment Monitoring
Program includes detailed baseline data of existing surface water and groundwater resources, a
program for the ongoing development and use of appropriate surface water and groundwater models,
a program to monitor and assess impacts on surface water and groundwater resources, and a
program to validate and calibrate the surface water and groundwater models.
The Long-wall 20-22 Water Management Plan prepared to manage the potential environmental
consequences of the Extraction Plan on watercourses (including the Woronora Reservoir), aquifers
and catchment yield was prepared in accordance with Project Approval Schedule 4 condition 6 and
this also addresses catchment management in relation to the areas affected by Long-walls 20-22
development.
Catchment Monitoring Program: 2
Although the baseline groundwater data reported in the Catchment Monitoring Program is considered
to satisfy the Project Approval, improvement could be made by inclusion of the following information
in the monitoring program:
Groundwater flow contours for the different aquifers;
Data on aquifer properties such as hydraulic transmissivity and storativity;
A more comprehensive review of water quality trends and characteristics;
Rainfall data on hydrographs.
4.7 Construction Management Plan
[Project Approval Schedule 3 condition 11]
A Construction Management Plan for the surface works for the Eastern Tributary and Honeysuckle
Creek Gauging Stations construction in the Woronora Special Area was prepared to satisfy Project

26 July 2011. DoP responded with comments on 31 October 2010 and the revised Construction
Management Plan was submitted to DP&I on 29 April 2011.
