6.6.         Corrective and Preventative Action
An environmental incident with respect to the ESCP is defined as any occurrence where sediment is
released from the site, whether controlled or uncontrolled, or where stormwater is released (controlled)
from site which does not meet the water quality requirements.

All incidents and non-conformances are to be reported, investigated and corrected in accordance with the
ESCP to ensure effective soil and water quality management practices at all times.

Best practice site management requires all ESC measures to be inspected by the Contractors nominated
representative at least daily when rain is occurring, within 24 hours prior to expected rainfall, and within 18
hours of a rainfall event of sufficient intensity and duration to cause onsite runoff (IECA, 2008). Such
inspections must check:
