GRANTS PASS, Ore. (AP) — Some rural residents of Curry County are asking federal environmental and health agencies to join an investigation of complaints that people got sick after herbicides meant for neighboring timberlands fell over their homes.The petition of behalf of two dozen people was sent Thursday to the U.S. Environmental Protection Agency, the Centers for Disease Control and Prevention, and the Agency for Toxic Substances and Disease Registry.Lisa Arken of Beyond Toxics says they hope to get the same kind of investigation that has been going on in Lane County, where residents around Triangle Lake have made similar complaints.The Oregon Department of Agriculture has been investigating since the spraying took place Oct. 16 in an area north of Gold Beach. Complaints include vomiting, lack of balance, and joint pain.The Oregon Herald is a non-commercial, ad free, daily news publication updated every hour.
