Emissions to air

Under Part 1 of EPA 90, an IPC system eontrols emissions to air, land and water for the most polluting industrial and similar proeesses. All operators of preseribed proeesses, e.g. fuel and power, minerals, waste disposal and ehemieal, require prior authorization. They are required to use BATNEEC, the Best Available Teehnology Not Entailing Exeessive Cost ... 

Under Part I of the act an IPC system controls emissions to air, land or water for the most polluting industrial and similar processes. IPC is limited to prescribed processes (e.g. chemical, fuel and power, waste disposal, minerals etc.) by prior authorization. Authorization is based on the requirement for owners/controllers to prevent release of prescribed substances or, where this is not practicable, to reduce the release to a minimum. Any residual release must be rendered harmless. To achieve these aims, operators must use the best practicable means not entailing excessive cost (BATNEEC). 

An environmental audit is a systematic examination of how a business operation affects the environment. It will include all emissions to air, land, and water and cover the legal constraints, the effect on community, the landscape, and the ecology. Products will be considered, as well as processes. 

The aim of the Life Cycle Impact Assessment (LCIA) is to facilitate the interpretation of the results of the inventory analysis. The result of the inventory analysis is an emission profile for each alternative system. In this study the emission profile is the total of all emissions to air, water and soil from the grave-to-cradle chain for the use of cushion vinyl floor covering, including the up chain processes, like electricity production and the down chain processes, like the incineration and landfill of the waste. Such an emission profile may consist of hundreds of emissions and extractions. In LCA impact assessment the total of interventions (emissions, extractions) of a process chain is evaluated in terms of environmental problems (impact categories).

In order to achieve dramatic reductions in hazardous emissions to air in urban areas, it is therefore recommended that the domestic standards for gasoline limit benzene to 2 % and total aromatics to 45 %. 

The various elements that must be linked as part of an a priori methodology for relating emissions to air quality are shown in Fig. 1, where the mathematical model provides a framework for integrating the following basic components. 

The time-series analysis results of Merz et were expressed in first-order empirical formulas for the most part. Forecasting expressions were developed for total oxidant, carbon monoxide, nitric oxide, and hydrocarbon. Fitting correlation coefficients varied from 0.547 to 0.659. As might be expected, the best results were obtained for the primary pollutants carbon monoxide and nitric oxide, and the lowest correlation was for oxidant. This model relates one pollutant to another, but does not relate emission to air quality. For primary pollutants, the model expresses the concentrations as a function of time.
