The Contingency Management Manual (CMM):
• Aims to address Condition OP3 of the site Environment Protection Notice (EPN)
• Provide quick reference of how to respond in case of unplanned events, not covered by normal operations, that have the potential to impact beyond the normal sewage treatment plant (STP) operating boundaries.
Note: for unplanned events associated with STP operations, refer to the Operations and Maintenance Manual.

Types of incidents and response cards
Unplanned events have the potential to affect STP operations and cause incidents beyond the site operational boundaries. Incidents addressed by the CMM site response procedures include:
• IEM-PRO03 – Excessive wet weather e.g. maintenance hole overflow (for Mechanical STPs)
• IEM-PRO04 – Excessive wet weather (for Lagoons STPs)
• IEM-PRO05 – Flood e.g. nearby river flooding (for all STPs)
• IEM-PRO06 – Spill to water e.g. lagoon spill into estuary (for all STPs)
• IEM-PRO07 – Spill to land e.g. lagoon spill onto adjacent oval (for all STPs)
• IEM-PRO08 – Power failure e.g. storm causes 24 hour outage (for Mechanical STPs)
• IEM-PRO09 – Power failure (for Lagoon STPs)
• IEM-PRO10 – Fire e.g. bushfire causes power outage (for all STPs)
• IEM-PRO11 – Odour e.g. neighbour complains of odour (for all STPs)
• IEM-PRO12 – Noise e.g. complaints about excessive noise (for all STPs)
• IEM-PRO13 – Loss of disinfection e.g. disinfection failure (for relevant STPs)
• IEM-PRO14 – Blue green algae (BGA) e.g. cyanobacteria >5,000 cells/mL Note: only for lagoon systems.
One of the above listed response procedures and/or IEMP response procedure may be referred to during an incident. These cards should be kept on site.
Operational failures: refer to the Operation and Maintenance Manual contingency management sections.

First responder/operator
1. Respond to prevent or control the incident. Refer to site card and appropriate site response cards
2. Assess the situation to determine the incident level or potential level
• Pre-incident Alert level: information has been received indicating an incident is imminent or may occur in the near future
• Incident Level 1: where local work teams operate under normal supervision with some additional managerial and localised support. The response team can effectively cope with minor effect on TasWater, its customers and the community
• Incident Level 2: can be controlled at the site level by an onsite commander, but may need additional resourcing; and/or multiple incidents that impact TasWater; and/or emergency services are required; and/or regulatory authorities give directions; and/or the actual or potential impact on TasWater, its customers, the community and the environment is more widespread
• Incident Level 3: requires external agency to be the response management agency and will require activation of the Strategic Recovery Team to manage the broad range of corporate and strategic issues that may emerge from the event and is not addressed directly by the CMM.
3. Notify the coordinator.
Coordinator (Level 5)
4. Assess: review the situation to confirm the incident level or potential level (Alert or Level 1, 2 or 3)
5. Notify: the managers (Level 4 and Level 3) as per CMM site response cards
6. Command and control: set objectives and develop strategies and use them to instruct operators and first responders to prevent further impact and control the incident
7. Manage and recover: to reduce impact when possible
8. Improve: undertake post-incident investigation, report and recommend improvement actions.
