Costa Rica Reglamento Olores OfensivosThe government of Costa Rica has published a Draft Regulation for the control of offensive odours that establishes limit values for odour in ambient air. The draft is in the public consultation phase which ends tomorrow, the 17th. This legislation establishes limit values of 3, 5 and 7 odour units in ambient air for a list of activities potentially generating odour nuisance, without specifying any percentiles. In addition, a general value of 10 odour units is established for any activity not mentioned in the above list.

P34Ip   In order to improve the quality of life of people, the Ministry of the Environment of Chile is strengthening the regulatory framework for odours. In this context, the main objective of this paper is to present a design proposal for an odour regulation, based on international experience and the national situation.

   The proposal has an integrated perspective, with a technological approach. This include not only odours limit but also, operational practices, in order to raise the operating standard of the sources and the reduction of odour emissions.

 arcelormittal taranto  The region of Apulia in sourthern Italy published last year a new legislation on odour management, the Legge Regionale Puglia 32/2018. This legislation was a bit different from other odour legislations around the world cause it defined different odour impact criteria (OIC) according to the sensitivity of the people affected by the odour impact. Last week the Constitutional Court of Italy repealed this new legislation. Why?

 Taranto is a beautiful coastal city in the region of Apulia that happen to be also the location of Europe's largest steelworks. This factory, now part of ArcelorMittal, was key in Italian 2018 election campaign. At that time the Italian party Five star Movement promised to close the factory after years and years of odour complaints and other environmental issues.
