The requirements of a licensing framework for work with legacy products are consistent across each of the proposed options .
Importantly , the licensing framework for work with legacy products proposed is largely an administrative framework that ensures regulators are aware of which PCBUs are undertaking this work . This is because existing regulations , including the prohibition of uncontrolled processing of engineered stone ; and the additional requirements agreed for Option 5a of the Silica Decision RIS ( including requirements for risk control plans , training , air and health monitoring , and reporting ) would already apply and no additional regulations are proposed .
3.4 Option 2 : Prohibition on the use of engineered stone containing 40 % or more crystalline silica
This option would limit the prohibition described for Option 1 to engineered stone containing 40 % or more crystalline silica ( higher silica engineered stone ).
The use of engineered stone containing less than 40 % crystalline silica content would be subject to the additional regulation as described in Option 5a of the Silica Decision RIS and agreed by WHS ministers .
This option also includes a licensing framework for work with legacy products , as described for Option 1 . Where the crystalline silica content of the legacy product is 40 % or more , or where it cannot be determined , a PCBU would need to apply for a licence to work with legacy products to undertake removal , repair or modification work .
3.5 Option 3 : As for Option 2 , with an accompanying licensing scheme for PCBUs working with engineered stone containing less than 40 % crystalline silica
In addition to the prohibition on the use of higher silica engineered stone proposed in Option 2 , Option 3 also outlines an additional licensing framework for PCBUs working with lower silica engineered stone (< 40 % crystalline silica content ).
This would result in 2 separate licensing frameworks for PCBUs working with engineered stone : �
� the previously described licensing framework for work with legacy products with higher , or unknown , silica content , and a licensing framework for work with lower silica engineered stone – for those PCBUs who fabricate ( cut , shape , polish etc ) and / or install new engineered stone products that have a crystalline silica content below 40 %.
