Does upgrading or renewing an existing piece of equipment change the requirements for the sampling position?
Upgrading or renewing equipment generally provides an opportunity to ensure a sampling plane compliant with AS 4323.1-1995 is made available. For example, if the work includes renewing the existing stack, this would be considered an appropriate opportunity to construct a new stack that is compliant with the requirements of the Standard. However, if the work is limited to upgrading equipment upstream of the emission point but retains the existing infrastructure of the emission stack, the requirements of the sampling position remain those applicable to the existing infrastructure.
