In Japan, the total emission rate of SO2 of target area is determined so as to meet the national air quality standard of S02, which is called the Total Quantity Control (TQC). The principle and techniques of such control procedure are described in this paper.
TQC starts with the simulation of hourly SO2 concentration based on the diffusion theory, which connects the concentration with emission rate via meteonological factors. The annual mean concentration is computed from the hourly value using meteorological statistics. If the annual mean concentration at any point of target area thus computed exceeds the national standard, the emission rates are reduced so as to meet the national standard.
