8/28/2014 Perry wanted to know if he should try to conduct Method 9 opacity observations on a day like today (i.e. rain, low overcast, and a very long steam plume). I told him that the readings would not be accurate so I would not expect them to be conducted. However, I did tell him to document that readings were not possible due to weather conditions.
