The Odour Special Interest Group (OSIG) of CASANZ has recently sent a newsletter commenting that the Environment Protection Authority Victoria (EPA Victoria) has released two new publications in the lead up to the Environment Protection Act 2017 that are effective since 1st of July 2021.
The first guidance deals with biofilter design and maintenance and has the title EPA Publication 1880: Biofilter design and maintenance. This guide provides information for industry, consultants and assessors on how biofilters can be constructed and operated. The second guidance provides three methodologies to carry out field inspections. The EPA Publication 1881: Guidance for Field Odour Surveillance provides a recommended approach for conducting odour surveillance to evaluate the extent, source and frequency of odour emissions.
