     Since the ISC models use direction‑specific building dimensions for all sources subject to building downwash, there are no building parameters entered on the SRCPARAM card. Building dimensions are entered on the BUILDHGT and BUILDWID cards described below in Section 3.3.3.

3.3.2.2 VOLUME Source Inputs.

     The ISC VOLUME source algorithms are used to model releases from a variety of industrial sources, such as building roof monitors, multiple vents, and conveyor belts.  The syntax, type and order for the SRCPARAM card for VOLUME sources are summarized below:

Syntax:

SO SRCPARAM  Srcid Vlemis Relhgt Syinit Szinit

Type:

Mandatory, Repeatable

Order:

Must follow the LOCATION card for each source input

where the Srcid parameter is the same source ID that was  entered on the LOCATION card for a particular source, and the other parameters are as follows:

Vlemis ‑     volume emission rate in g/s,

Relhgt ‑     release height (center of volume) above ground, in meters,

Syinit ‑     initial lateral dimension of the volume in meters, and

Szinit ‑     initial vertical dimension of the volume in meters.

It should be noted that the same emission rate is used for both concentration and deposition calculations in the ISC models. The following table, which is explained in more detail in Section 1.2.2 of Volume II of the User's Guide, summarizes the suggested procedures to be used for estimating the initial lateral and vertical dimensions for various types of volume and line sources.
