4.3.2 Costs of a licensing framework for work with legacy products
When WHS ministers requested the Agency undertake further consultation and analysis on the impacts of a potential prohibition on the use of engineered stone , they asked that this include a licensing system for work with legacy products – that is , for example , removal , repair and minor modification of engineered stone installed in homes and other premises prior to the prohibition .
To enable the modelling underlying this Impact Analysis , an assumption was made that such work would likely be undertaken by a different group of PCBUs ( other industry PCBUs ) to those undertaking the fabrication and installation of engineered stone ( engineered stone PCBUs ).
The costs of a licensing framework for work with legacy products are consistent across each of the options presented in this document .
For PCBUs , these costs include : � labour costs associated with licence application
� labour costs associated with licence renewal every five years , and � preparation and participation in licence compliance audits .
The licensing framework for work with legacy products will involve changes to the model WHS laws but is not proposed to be accompanied by any additional regulatory requirements . In accordance with the base case , PCBUs will need to comply with existing regulations including the prohibition of uncontrolled processing of engineered stone ; and the additional requirements agreed to under Option 5a of the Silica Decision RIS including requirements for risk control plans , training , air and health monitoring , and reporting ).
Costs to government for a licensing framework for work with legacy products include : � drafting of relevant legislation
