Four Corners Power Plant

Four Corners Power Plant, New Mexico Coal... 

The Kr value is similar to other measurements for dry summer daytime conditions. The Kd value is larger than what is frequently assumed, but not implausible. For example, in the Four Corners power plant plume study of Mamane and Pueschel (10), in complex terrain similar to that considered here, a particle dry deposition rate of 18%/h was found. Since particles typically are dry-deposited at much lower rates than S02, a 31%/h excess deposition rate for SO2 does not appear unreasonable.
