Loretta,
Please accept this email as notification that on Friday, August 15, we plan to start the trial using Ferric 
Sulfate as outlined in Item 1 of our request submitted on June 20, 2014.  As indicated in the request, the 
maximum dosage will not exceed 30 ppm.  It is expected that this treatment will reduce intermittent 
sublethal toxicity effects, as well as remove excess phosphorus at the end of the aeration 
basin.  Dissolved Iron and Total Iron will be tested weekly at Outfall 001 for the duration of the trials to 
ensure that the dosage is optimized.
