Evaluate, implement and monitor high-risk trade waste discharge approvals

Assessment tool

Version 1.0
Issue Date: December 2018


This unit supports the attainment of skills and knowledge required for trade waste officers or inspectors with a specific responsibility for managing applications and approvals for high-risk liquid trade waste discharges to wastewater collection systems from large and complex industrial organisations.

This unit of competency describes the outcomes required to assess and process applications for high-risk trade waste discharges from large and complex industrial organisations, monitor compliance with the trade waste approval issued and renew, amend, suspend or revoke trade waste discharge approvals as appropriate.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Prerequisites

Not applicable.


Employability Skills

The required outcomes described in this unit of competency contain applicable facets of employability skills. The Employability Skills Summary of the qualification in which this unit of competency is packaged, will assist in identifying employability skill requirements.




Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 consistent performance for each element across a representative range of applications

meet the Performance Criteria associated with each element by employing the techniques, procedures, information and resources available in the workplace from those listed in the Range Statement

demonstrate an understanding of the underpinning knowledge and the application of skills as described under Knowledge and Skills.

The candidate should demonstrate the ability to evaluate, implement and monitor high risk trade waste approvals, including:

advising customers of the trade waste management policies and procedures in operation

advising customers of requirements for obtaining and complying with trade waste discharge approvals

assessing and evaluating applications for high-risk trade waste treatment and disposal

implementing charging and monitoring procedures

completing records and reports.

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.

Method of assessment

The following assessment methods are suggested:

assessment in the workplace or in a simulated workplace and under the normal range of workplace conditions

assessment should also be conducted in conjunction with aspects of technical competencies that are consistent with the work environment

techniques for gathering evidence of competency may include:

observation of performance

written and/or oral questioning to assess knowledge and understanding

completion of workplace documents and reports produced as part of routine work activities

third party reports from experienced practitioners

completion of performance feedback from supervisors and colleagues.

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.
