Air pollution abatement technology

During the 9th week, you have learned about air pollution control technologies pertaining to a) Stationary Sources and b) mobile sources. Based on what you have read and learned, explain, WITH SOUND REASONS, whether the currently recommended technologies for control of air particulate and gaseous pollution are cost-effective, efficient and adequate, and are within the reach of small to medium size industries for complying with the requirements of air quality regulations? Please fully answer all the points that this assignment is asking for.

We can assess the adequacy of the current technologies by looking at air quality measurements currently available. There has been a significant reduction in SO2 in the air since the Clean Air Act was implemented, indicating that the technology for removing this pollutant has been widely implemented. Therefore, we can conclude that many businesses have found the technology to do this without great sacrifice. The current pollutants of concern (NOx, CO, and ozone) are generated by the motor vehicle traffic. Although new vehicles are much less polluting than older ones, the vast increase in traffic in recent years has caused the increase in these pollutants.

Small to medium sized industries, therefore, are not the primary reason for air pollution in most non-attainment areas. That is not to say that air quality regulations have not affected them. The challenges for small companies involve the maintenance costs which must be averaged into their total cost of production. Since the costs associated with maintaining air pollution abatement systems are similar for small are large plants, the per unit cost is effectively higher for small companies. In fact, your lecture notes indicate that some methods work best for a high volume stream, which a small plant is less likely to have. However, they have the advantage in that they are often not held to the highest standards. If their emissions are low enough, they can be considered "minor sources." While "major sources" required to demonstrate compliance with all relevant regulations, and to maintain extensive records, "minor sources" are generally subject to less scrutiny. However, the EPA has recently indicated the need to ...
