In a letter to EPA dated May 31, 2012, the U.S. National Marine Fisheries Service issued a final Biological Opinion on the effects of EPA’s registration of pesticides containing the active ingredients oryzalin, pendimethalin, and trifluralin on endangered species, threatened species and critical habitat that has been designated for those species.  NMFS’ BiOp concludes that pesticide products containing these three active ingredients are likely to jeopardize approximately half of the listed pacific salmonid ESUs/DPUs and adversely modify their designated critical habitat.
