A procedure with a potential for increasing the duration of tall stack plumes residency within elevated stable layers, outlined schematically. The suggested procedure considers the temporal and spatial behavior of the atmospheric boundary layers (ABL). It takes advantage of the fact that under adverse dispersion conditions, due to relatively shallow ABL, injection of the plume into the capping stable layer above the ABL, may be achieved by a modification of the emission parameters. When successfully applied it will undoubtedly lead to an increase in the time a plume travels within an elevated stable layer, thus ensuring reduced ground-level concentrations as compared to plumes trapped within shallow ABLs. The reduction may be from extremely high concentrations to extremely low concentrations. Application of the strategy is most attractive when the near-stack area is a residential area, while at greater distances from the stack the population is sparse. The technology and engineering involved with increasing emission parameters requires special attention, while the current state-of-the-art tools for forecasting the morning depth of the ABL are quite credible. The proposed strategy has the sole purpose of improving near-field ground-level air quality, in a particular set of meteorological conditions, while retaining the emission rate of gasesmore » or even reducing them when compared to normal emission levels.« less
