As announced, the 4th of August 2011, the Decree 239/2011, of 12th of July, that Regulates Quality in the Atmospheric Environment and creates the Register of Air Quality Evaluation Systems in Andalusia, was published in the Official Journal of the Regional Government of Andalusia.
This is the first autonomous administration in Spain that regulates potentially odour-emitting activities. This legal text authorises to the Regional Environmental Ministry of Andalusia to require to the legal owners of these activities, both previously and subsequently to the beginning of the industrial activity, the adoption of all means to reduce odour emission, including the completion of an odour impact study to prove that the selected abatement methods are suitable to prevent any affection to the residents.
The National Institute of Normalization (INN) in Chile has recently endorsed the new Chilean Standard NCh3190, Air quality. Determination of odour concentration by dynamic olfactometry, which is basically a transposition of the European EN 13725. The draft of this standard can still be consulted on the website of the Superintendence of Sanitary Services (SISS) of Chile.
The Environment Agency regulates odours under the Environmental Permitting Regulations by means of H4 Odour Guidance which focused on activities under the Pollution and Prevention Control (PPC) Regulations. This document is well known and it is widely used not only in the UK, but also in many other countries as reference guidance.
