PLM: Pollutant Loading Module

Estimates non-point source annual pollutant loadings according to the Appendix B procedure of the State of California Best Management Practices (BMP) Handbook (Municipal). The computer program allows for editing of the Event Mean Concentration (EMC) coefficients for each of the pollutants analyzed (see cited BMP Handbook), and is initialized using standard NURP EMC coefficients.

The PLM interfaces with RATSCx and HydroLINK, enabling an automatic Computation of annual pollutant loadings given RATSCx data files.
