This unit of competency describes the outcomes required to investigate trade waste incidents, make arrangements for rectification and to complete reports.
Notes
Elements and Performance Criteria
1Analyse trade waste incident location.
- 1.1 Identify and confirm the location and nature of trade waste incidents.
- 1.2 Assess the extent of incidents and the possible effects.
- 1.3 Implement actions or make recommendations, as required, to minimise potential harm.
- 1.4 Notify relevant organisations and individuals.
- 1.5 Conduct inspections and sampling of incident locations and environs and analyse and report findings and results.
2Investigate the cause and effect of trade waste incidents.
- 2.1 Identify and confirm the wastewater catchment for incident locations.
- 2.2 Analyse the wastewater catchment for possible sources of unauthorised or illegal discharge.
- 2.3 Schedule inspections of potential sources of unauthorised or illegal discharge and make appropriate preparations.
- 2.4 Investigate the possible effects of trade waste incidents and assess the level of severity.
3Identify incident source and arrange rectification.
- 3.1 Conduct inspections of potential sources and gather and record evidence.
- 3.2 Analyse evidence and where possible, confirm the correct source of unauthorised or illegal trade waste discharge and complete required documentation.
- 3.3 Identify, analyse and select methods for rectifying problems.
- 3.4 Consult appropriate personnel within the identified customer organisations and advise of rectification requirements and incident repercussions.
4Compile trade waste incident reports.
- 4.1 Record and process data and information relating to investigations and evidence gathered according to organisational and statutory requirements.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.
Trade waste may include:
the liquid waste generated by any:
industry
business
manufacturing process
community/public facilities
commercial activities
trade waste does not include domestic wastewater
Organisational and statutory requirements may include:
relevant legislation, for example:
the Environmental Protection Act
Environment Protection and Biodiversity Conservation Act
Waste Minimisation and Management Act
the Water Act
local by-laws
International Standards, for example:
ISO 14000 standards
Australia/New Zealand Standards, for example:
National Plumbing and Drainage Code AS/NZS 3500
relevant industry codes of practice for the management of trade waste, for example:
industry Code of Practice for the Photographic Industry (PURE)
National Health and Medical Research Council's (NHMRC) National guidelines for waste management in the health care industry, 1999

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The candidate should demonstrate the ability to investigate, rectify and report on trade waste incidents, including:
identifying and analysing incident locations
assessing the type and extent of incident impact
assessing the trade waste catchment and identifying possible sources of the problem
investigating possible sources and identifying the instigators of the incidents
investigating the instigating organisations and negotiating rectification measures
completing comprehensive reports appropriate for prosecutions
Context of and specific resources for assessment
Access to the workplace and resources including:
documentation that should normally be available in a water industry organisation
relevant codes, standards, and government regulations
Where applicable, physical resources should include equipment modified for people with disabilities.
Access must be provided to appropriate learning and/or assessment support when required.
Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed.
Validity and sufficiency of evidence requires that:
competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice
a decision of competence should only be made when the assessor has complete confidence in the person's competence over time and in various contexts
all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence
where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time
assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit
In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator, any cultural issues that may affect responses to the questions, and reflecting the requirements of the competency and the work being performed.
