4.1     Erosion and Sediment Control
An Erosion and Sediment Control Plan (ESCP) is to be prepared for the Operational Works permit with
the aim of avoiding degradation of receiving waters and erosion of soil by implementing control
measures during the construction phase.

Table 2 below details the strategies for erosion and sediment control. The Project Manager is the
responsible person and is to undertake regular monitoring.
