Elements and Performance Criteria

1. Analyse trade waste incident location.
   • Identify and confirm the location and nature of trade waste incidents.
   • Assess the extent of incidents and the possible effects.
   • Implement actions or make recommendations, as required, to minimise potential harm.
   • Notify relevant organisations and individuals.
   • Conduct inspections and sampling of incident locations and environs and analyse and report findings and results.
2. Investigate the cause and effect of trade waste incidents.
   • Identify and confirm the wastewater catchment for incident locations.
   • Analyse the wastewater catchment for possible sources of unauthorised or illegal discharge.
   • Schedule inspections of potential sources of unauthorised or illegal discharge and make appropriate preparations.
   • Investigate the possible effects of trade waste incidents and assess the level of severity.
3. Identify incident source and arrange rectification.
   • Conduct inspections of potential sources and gather and record evidence.
   • Analyse evidence and where possible, confirm the correct source of unauthorised or illegal trade waste discharge and complete required documentation.
   • Identify, analyse and select methods for rectifying problems.
   • Consult appropriate personnel within the identified customer organisations and advise of rectification requirements and incident repercussions.
4. Compile trade waste incident reports.
   • Record and process data and information relating to investigations and evidence gathered according to organisational and statutory requirements.
   • Compile, process and distribute incident reports, including rectification arrangements according to organisational requirements.
5. Conduct post incident monitoring to ensure ongoing compliance.
   • Adjust trade waste treatment and discharge monitoring schedules as required and prepare and apply a post incident monitoring plan.
   • Correctly select, fit and use personal protective equipment.
   • Identify and investigate breaches of the trade waste discharge provisions and report the results and/or recommendations according to organisational requirements.

Evidence Required

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 andor 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 persons 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 RCCRPL 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 projectbased 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

Range Statement

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 state plumbing and drainage code of practice requirements of regulatory authorities, such as: Water Authorities WorkCover EPA Health Department local council.
