new epa calpuff version   The USEPA approved in July 2016 an update of CALMET and CALPUFF from V5.8.4 to V5.8.5. This update includes code changes described in Model Change Bulletin H and include fixes to bugs in the implementation of PRIME downwash, along with updates to eliminate specific compilation and list file errors. Three years later after the last update approved by the US EPA, this second revision is still falling short for odour dispersion modelling.

   The CALPUFF Modeling System is a non-steady-state puff dispersion model that simulates the effects of time- and space-varying meteorological conditions on pollution transport, transformation, and removal. According to the US EPA CALPUFF can be applied for long-range transport and for complex terrain.

WEF Odor survey   The Water Environmental Federation (WEF) Air Quality & Odor Control Committee has developed a survey to benchmark industry efforts related to odor control and odor management. The results of this survey will be useful for utilities to know how their organization's activities compare to what others are doing. In addition, the results will also be useful for consultants, manufacturers, and researchers to understand gaps and needs.

   The Air Quality & Odor Control Committee is a very active team of the WEF that counts on around 60 members these days. The Air Quality & Odor Control Committee develops, recommends, and conducts programs to promote general improvement in reducing odor emissions impacts related to water quality, biosolids handling, treatment and disposal, and wastewater treatment and collection.The chair of the Committee is hold by Ms. Carla Dillon, from the planning division of the Orange County Sanitation District. Ms Dillon is a very well known person that has been working in the field of odor management for many years.   

wg41 tg2   Olores.org had the privilege of organizing the last meeting of the European Committee for Standardization (CEN) on 'Instrumental odour monitoring’. These meetings were organized last week in our home town of Bilbao, Spain. It was a pleasure to meet all the colleagues in our city and to discuss for two days about odour management and instrumental monitoring.

   In the last meeting of the Working Group (WG) 41 in Delft, after several discussions on the scope of the norm, the title of the norm was changed from 'sensor technologies' to 'technologies for instrumental odour monitoring' instead. One of the reasons behind this decision was a hot debate about including other "odour monitoring" devices such as a Gas Chromatography, for example. However, we will use the word 'o-sensor', to keep it short and to make a clear distinction between these devices and the ones incorrectly named as 'e-noses'.
