Description
Summary:Odors are being increasingly recognized as a source of nuisance. Public complaints on odor nuisances have resulted in hearings and subsequent closure of plants in the chemical process industries (CPI). Odors and the potential for nuisances associated with the operation of industrial plants, water- and wastewater-treatment units, municipal landfills, and other possible sources therefore need to be evaluated and abated in an objective manner. In many cases, odorous emission sources become known through the course of operation of plants, especially startup, shutdown, and upset conditions. Since odor thresholds for many compounds are quite low, the overall accuracy of the sampling-and-analysis program should be ensured through good quality assurance and quality control practices. Most odor abatement programs implemented by the CPI focus on point-source controls. However, fugitive sources can contribute significantly to odor nuisances. Control of fugitive sources can be achieved by an effective leak-prevention program and a comprehensive monitoring program.
