discharge point within the steel plant (table 1). The MINAS is defined as the maximum
concentration of pollutants allowed per unit of gas emitted.

* During oxygen lencing, otherwise norm is 150 mg/Nm³.

** For power plants less than 200 MW, emission norm is 350 mg/Nm³.

5. The Data

It may be noted here that though the analytical model presented in section 2 can
be used to design both inter-plant as well as intra-plant emission trading, in this paper,
however, the model is applied to examine intra-plant trading in an integrated steel
plant. The Bokaro Steel Plant (BSP) is selected as a case study. The data has been
obtained from the plant by means of a questionnaire, and several rounds of personal
discussions with the staff of the environment management division at the BSP as well
as the corporate office of SAIL at New Delhi.

Owing to the nature of SPM (non-uniformly mixed pollutant) an air quality
modelling technique is used to determine the ambient air quality that would be obtained
in the baseline emission scenario in the local airshed (20 x 20 km area around the steel
plant) and in the emissions trading scenario. The baseline emission scenario refers to
the situation in which the prescribed (legislated) point source emission standards are
met at all the discharge points at the steel plant. As noted earlier, the estimates of
transfer coefficients for each discharge point for the receptors affected by its emissions
