Process Change: This technique involves a modification of an existing process or the introduction of a new process. Since 90’s the process change has been known as “pollution prevention”. Consider the example of painting operations in automobile industry. Large quantities of volatile organic compounds and hazardous air pollutants were released as a result of these operations. After the passage of 1990 CAAA many operations have substituted water based, low HAP paints for oil based paints for reducing emissions. Some operations have implemented processes such as electro-deposition, dip tank and powder coating.
Change in Fuel: This technique involves the use of less polluting fuel to reduce air pollution. Use of low sulfur fuel instead of high sulfur fuel by electric utilities is an example of this method. Remember that low sulfur fuel is much more expensive than high sulfur fuel. The other choice for an electric utility can be the use of natural gas as a fue
Improve Dispersion: This approach is based on the concept that dilution of air contaminants before they reach ground will lower the concentrations to which the population is exposed. The use of this approach for industry is discouraged by the US EPA. However, local and state agencies use the concept to develop air pollution control strategies for their area.
Good Operating Practices: Release of unnecessary air pollutants could be avoided by maintaining good housekeeping in the plant and performing proper maintenance. For example, liquid chemicals spread over the floor evaporates rapidly and will cause an increase in emission rate for that chemical.
Plant Shutdown/Relocation: This is not a pleasant solution for a community because of economic impact. Most cities develop land-use planning and industrial zoning regulations to avoid this situation. Encouragement to use new technology through tax credits or grants may help a company to relocate the plant within the city. In some cases to shutdown the plant is only viable solution.
