dcaimanque3   Chile is now undertaking the preparation of three odour regulations for: Swine's farms, the sea products processing plants and it has started the process of reviewing the emission standard for pulp mills. Carrying out regulatory processes to solve the issue of annoying odours is not an easy job, because it has different characteristics compared to the rest of the atmospheric pollutants.

   However, the development of normative processes in Chile has so far provided important learning instances for each of the obstacles that have had to be overcome. Thus, the main objective of this work is to disseminate three lessons learned from the odour standards development processes in Chile. The results of this work are expected to contribute to other normative processes that will be initiated, particularly in Latin American countries.

epa victoria guidances   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.
