An environmental group is appealing the government’s decision to allow the aerial spraying of a bacterial pesticide in West Kelowna. …the local group, the Kelowna Citizens Safety Association, wants the spraying halted until “a comprehensive risk assessment can be conducted for the citizens and passersby”, per a press release issued Thursday. The group’s leader, Lloyd Manchester, says a formal appeal against the spraying has been filed with the B.C. Environmental Appeal Board. Current plans are for the spray to be spread over the area from airplanes flying approximately 100 feet above the ground, Manchester says. He says other treatment methods against the spongy moths should be pursued.
