The report gives test data from drift characterization and airborne salt monitoring studies conducted on and around a single-cell, mechanical-draft salt-water cooling tower and two spray modules at Turkey Point, Florida. Source measurements of drift droplet size distributions and mineral mass emissions were conducted for both devices during a winter test and for the tower alone during a summer test. Atmospheric salt concentrations and depositions were measured for 11 months, both with and without cooling device operation. Cooling tower drift droplet measurements yielded a drift emission fraction of 0.00027% of the water flow rate of 1260 kg/s, and a droplet mass median diameter of 120 micrometers. The average mineral mass emission rate was 0.00083% of the minerals circulating as solute in the cooling water. Droplet size spectra and mineral mass fluxes of the spray module drift emission were measured up to a height of 11 m above water level, below which the bulk of the drift was observed, and downwind to a distance of 88 m.
