In addition to these engagement sessions, an information package is available in the document section of this page (TOP, RIGHT HAND SIDE COLUMN). Take a look before completing the online survey below.


Click HERE to Take the Community Survey: The use of ProcellaCOR FX in managing Eurasian watermilfoil in Christina Lake

This survey is designed to gather community input regarding the potential use of ProcellaCOR FX in Christina Lake to manage Eurasian watermilfoil. In recent years, Eurasian watermilfoil infestations have grown more dense and widespread, negatively impacting recreational activities, cultural and traditional values, native flora and fauna, and more. The Regional District of Kootenay Boundary (RDKB) is exploring the potential use of a highly selective herbicide, ProcellaCOR FX, to help effectively control Eurasian watermilfoil infestations.

Your needs, interests, and opinions provided through this survey will help guide the RDKB in ensuring that community values and concerns remain central to the decision-making process as they explore options for effectively addressing the spread of Eurasian watermilfoil in Christina Lake.

All Christina Lake community members are encouraged to participate in the survey by 1 October.


CLICK HERE FOR THE LIVE WEBINAR LINK:

Thursday, 14 August, 6pm - 7pm, via Microsoft Teams (please note that this online session will cover the same content as the in-person community engagement session held on July 19).

    It is unlikely that the application of ProcellaCOR FX would affect CL Waterworks. Health Canada’s Pest Management Regulatory Agency determined that the presence of ProcellaCOR FX in drinking water does not pose a health risk. There are no restrictions on using water treated with the ProcellaCOR FX for drinking, swimming, or fishing. The Vermont Department of Health established a drinking water standard of a maximum of 3 mg/kg/day. This equates to a maximum concentration that is 400 times higher than the proposed concentration to treat Eurasian milfoil in lakes.

    The warning on the ProcellaCOR FX Safety Data Sheet comes from California’s Proposition 65, which applies more precautionary hazard criteria than many other jurisdictions. For example, some chemicals flagged under Proposition 65 are not considered hazardous by the US Occupational Safety and Health Administration.


    In Canada, Health Canada’s Pest Management Regulatory Agency reviewed over 100 studies on ProcellaCOR FX and concluded it does not pose a health risk when used as directed. Additional Independent assessments (https://caroga.town/wp-content/uploads/2023/07/ProcellaCOR-CT-DPH-1.pdf and https://www.mass.gov/doc/florpyrauxifen-benzyl/download) found low mammalian toxicity, with no clear indication of carcinogenicity, mutagenicity, or ability to cause reproductive effects, especially at the low environmental concentrations possible from its proper application. Section 11 of the Safety Data Sheet (https://sepro.com/Documents/ProcellaCOR_EC--SDS.pdf) covers toxicological information and states that the active ingredient in ProcellaCOR FX (florpyrauxifen-benzyl) did not cause cancer and did not interfere with reproduction in laboratory animals. The US Environmental Protection Agency also classifies it as “Not Likely To Be Carcinogenic To Humans” ( https://npic.orst.edu/chemicals_evaluated.pdf)

    With all that said, we recognize that “low risk” is not “no risk,” and we value your concerns. Our goal is to listen to your concerns and share evidence-based information and resources to assist the community in making an informed decision.
