Project Description:

The Department has prepared a draft permit and has made a tentative determination, subject to public comment or other information, to approve the application of Aluminum Sulfate ("alum") for a Honeoye Lake Pilot Project to examine alum's effects as a phosphorous inactivant. As proposed, a total volume of 315,691 gallons of alum would be applied within a 965 acre treatment area in the central portion of the lake, greater than 18 feet in depth, in the fall season. As reflected in the draft permit, the maximum allowable alum dosage rate would be 410.5 gallons per acre. Short- and long-term monitoring and reporting would also be required under the permit to determine the treatments effects on water chemistry and aquatic biota. A phosporus total maximum daily load (TMDL) was approved by the US Environmental Protection Agency (EPA) in 2019, requiring nutrient loading be addressed before the lake can be removed from the List of Impaired/TMDL Waters.
