6.3.4 Area and Open Pit Source Emissions

For area and open pit source emissions, Equation (1-65) is changed to the form:


where K, D, Vd, and vd are defined in Equations (1-1), (1-54), (1-65), and (1-80). The parameter QAJ is the total mass per unit area emitted over the time period J for which deposition is calculated. The area source integral is estimated as described in Section 1.2.3.
