Concerns Over Use of ProcellaCOR Herbicide in Chautauqua Lake

On May 31, 2024, the following notice regarding ProcellaCOR was sent from the CLA to the Chautauqua County Legislature, the County Executive and all mayors / supervisors around Chautauqua Lake.

NOTICE FROM THE CHAUTAUQUA LAKE ASSOCIATION 

Your Chautauqua Lake Association has just received a communication from the Lake George Association that raises concerns about the continued application of the ProcellaCOR herbicide to control Eurasian watermilfoil in Chautauqua Lake. Typically, NYSDEC-permitted ProcellaCOR applications occur in the lake during the months of June/July. 

We thought our members and the lake’s surrounding towns and villages should be aware of this information, which has led Minnesota to condition approvals for further application of this herbicide in the “Land of 10,000 Lakes” only for unavoidable instances when alternative means are not available. 

The full Minnesota Department of Agriculture report to the Minnesota Legislature can be found online at https://www.lrl.mn.gov/docs/2024/mandated/240221.pdf 

Our Lake George partners commented as follows: “We learned last week that the Minnesota Department of Agriculture identified florpryauxifenbenzyl, the active ingredient in ProcellaCOR, as a PFAScontaining pesticide. Even when the active ingredient in ProcellaCOR degrades, the resulting degradants retain the Fluorine- Carbon bond that Minnesota determined to be a PFAS pesticide. As you may know, PFAS is a class of “Forever Chemicalsthat cause cancer and have contaminated drinking water supplies in communities across the country, including here in New York.” 

We are also concerned that PFAS is being added to Chautauqua Lake water and sediment via ProcellaCOR EC, together with the fact that it will not degrade and disappear. We understand that there is current litigation seeking compensation from as many as two dozen manufacturers for harm caused by PFAS. 

We additionally understand that the New York State Constitution Green Amendment of 2023 now places the onus on governments at all levels to identify how actions they take will protect a lake’s health.
