The EPA released advice and recommendations on stages three and four of the power station on Monday.

Authority chairman Paul Vogel said it was unlikely the EPA’s objectives would be compromised provided Griffin complied with the recommended conditions.

“The results obtained from the health risk assessment indicate atmospheric emissions from the proposed generating plants are unlikely to have a significant impact on human health at nearby sensitive receptors,” he said.

“The emissions from the Muja A and B generating plants are predicted to have the most significant impact in this regard.

“Predicted exceed-ances of the National Environment Protection Measure (NEPM) standard are largely due to SO2 emissions from Muja Power Station.” Mr Vogel said the NEPM standard is not predicted to be exceeded within the Collie town site.

He said the EPA has recommended a condition to limit stack emissions from the two proposed units.

“For greenhouse gas emissions Griffin has indicated that the proposed generating plants would be designed and constructed to be carbon capture and storage ready,” he said.

“However, the ‘where, when and how’ of the carbon capture and storage has not been delineated by the proponent and the likelihood that carbon capture and storage will become technically and commercially viable in the near future is uncertain.

“Among other greenhouse gas related conditions the EPA has recommended is a condition requiring retrofitting of carbon capture and storage within five years of the technology becoming economically and technically proven,” he added.
