5. Conduct pre-start checks

6. Liaise with other work areas as required

7. Demonstrate wastewater system operating procedures in both manual and automatic modes

8. Demonstrate first flush system operating procedures in both manual and automatic modes

9. Monitor waste water system operation. This typically includes monitoring:

chemical addition rates and residuals

temperatures

flow rates

equipment condition including calibration of instruments.

tests as required

dissolved oxygen levels

pH

levels

10. Conduct water quality tests

11. Take corrective action in response to out-of-specification results or non-compliance

12. Monitor supply and quality of waste water to and from the process

13. Report and/or record corrective action as required

14. Demonstrate emergency procedures to control chemical spills or other major incidents relevant to the workplace

15. Demonstrate shift handover procedure

16. Demonstrate an operational shut down procedure

17. Maintain workplace records to meet the requirements of the workplace and site environmental authority

18. Maintain work area to meet housekeeping standards

May include ability to:

19. Use process control systems

Knowledge of:

20. Relevant state OHS legislation, environmental acts and policies, standards and codes of practice relating to work responsibilities. This includes awareness of standards set out in site license arrangements

21. Safe work procedures including awareness of health and safety hazards related to waste water system operation and associated control measures. Hazards typically include handling chemicals, manual handling and flammable gases

22. Hierarchy of hazard control measures

23. Purpose and limitations of protective clothing and equipment

24. Methods used to render equipment safe to inspect, maintain and/or clean including lock-out, tag-out and isolation procedures

25. Water cycles for trade waste, storm water and sewerage including sources and flow patterns

26. Purpose and standards required by environmental agreements and responsibilities

27. Company policy relating to environmental performance

28. Consequences of non-conformance

29. Waste characteristics and treatment methods

30. Sampling and test procedures as appropriate

31. Purpose of chemicals used

32. Purpose of first flush systems and their relationship with the wastewater treatment system

33. Operating requirements and parameters

34. Water quality sampling and test procedures. This includes purpose of test and safe use, care and storage of relevant test equipment, interpretation and recording of results

35. Typical causes of non-conforming water quality and corrective action required

36. Equipment purpose and basic operating principles of waste water treatment equipment and methods

37. Requirements of both operational and long term shut down conditions to ensure the equipment is left in a safe state for the period of the shutdown and to minimise any delays in future start up

38. Housekeeping standards for the work area

39. Reporting and recording systems. This includes both statutory and workplace requirements

May include knowledge of:

40. Basic operating principles of process control where relevant. This includes the relationship between control panels and systems and the physical equipment

Relationship with other standards

Pre-requisite units

There are no pre-requisite units for this competency standard.

Co-assessment of related units

Other units of competency relevant to the work role should be assessed in conjunction with this unit. This may include:

SUGZPCI2A Operate a process control interface

Resources required for assessment

Assessment must occur in a real or simulated workplace where the assessee has access to:

Waste water treatment systems and related chemicals

Test equipment

Relevant advice on environmental agreements

Operating procedures and related advice on equipment operation

Personal protective clothing and equipment

Communication systems and equipment

Housekeeping standards and procedures

Workplace information recording systems, requirements and procedures

Assessment requirements

For information on how to assess this competency standard and who can assess, refer to the Assessment Guidelines for this Training Package.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Not applicable.

The range statement indicates the context for demonstrating competence. This statement is a guide and unless otherwise indicated, items may or may not apply as required by the work context.

Work is carried out in accordance with company policies and procedures, manufacturer's recommendations, legislative requirements, site licenses and trade waste service agreements and industrial awards and agreements. Legislation refers to environmental acts and regulations

Workplace information can include Standard Operating Procedures (SOPs) and manufacturer's specifications

Equipment may include screens, ph correction, oil/grease skimmers, settling and treatment ponds, aeration units, lagoons, first flush systems and wetlands, pumps and valves

Confirming equipment status involves conducting relevant pre-start checks, confirming that cleaning and calibration standards are met, all safety guards are in place and equipment is operational

Operation and monitoring of equipment and processes may require the use of control panels and systems

Typical tests may include pH, solids, colour/turbidity, flow rate, settling rate, settled volume, DO and BOD/COD levels

Work may require the ability to work within a team environment

Information systems may be equipment-based or remote from the treatment plant

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
