U.S. EPA Proposed Benzene Fenceline Monitoring for Refineries Amongst Other MACT and NSPS Changes
U.S. EPA has proposed an amendment to 40 CFR Parts 63, Subpart CC and Subpart UUU that requires all petroleum refineries to deploy passive time-integrated benzene samplers at the fenceline (where fenceline is equivalent to the facility property line) of their facility to alert them of fugitive emissions from leaks of Subpart CC and UUU process equipment. The proposed amendment also requires the ...

On the behaviour of air pollutants released from elevated stacks in the vicinity of Athens, Greece
The main features that characterise the Athens Metropolitan Area (AMA) are its geographical position in the Attic Peninsula, the complicated topography and the neighbouring industrial zone, located to the west and separated from the AMA by a hilly area. The transport of air pollutants from this zone to Athens has been the subject of a number of theoretical and experimental studies. In this paper, ...

A 3-D wind and temperature pre-processor for ATD models
Many atmospheric transport and dispersion models, based on various approaches and applied to different spatial scales, need 3-D meteorological fields referred to regular grid systems. Data generally available, however, cannot be directly employed because of their irregularities, inconsistencies, insufficient spatial detail or inadequate terrain representation. To fill the gap between these input ...

Realistic approach to 2-D flow modelling for complex terrain
The capabilities of regional and mesoscale meteorological models make them attractive to use in air pollution studies. Especially, flow modelling and dispersion analysis in complex terrain plays an important role in the control of emissions into the atmosphere. In the numerical simulation of an atmospheric phenomenon, various coordinate systems are used to represent the terrain and the vertical ...

Verification of wind energy related measurements with a SODAR system
Abstract Complex terrain and growing wind energy converters (WEC) in wind parks generate increasing interest in determining wind profiles and turbulence besides the general forecast of annual energy production. Increasing hub heights and growing rotor diameters of advanced WEC make SODAR systems a valuable alternative to meteorological towers. SODAR systems provide wind profiles as well as ...

Chemical risk management
The most severe industrial accidents are those involving dangerous chemicals, as they represent a significant threat to health and the environment. Furthermore, such accidents cause huge economic losses and disrupt sustainable growth. However, the use of large amounts of hazardous chemicals is inevitable in some industrial sectors that are essential to a modern industrialized society. To minimize ...
