Subsequent to providing AERMOD modeling data to the Coronado National Forest for the Final Environmental Impact Statement (FEIS) in support of the Rosemont Copper Project (Rosemont), the Forest Service (FS) requested that gaseous deposition results also be provided for the Saguaro National Park East (SNPE). Except for a very small portion, the SNPE lies within 50 KM of the Rosemont site. Consequently, gaseous deposition modeling was conducted using the AERMOD model which is the recommended for such distances. This memorandum provides the predicted gaseous deposition rates at the SNPE.
