Great Lakes United urges the governments of Canada and the United States to: Assess all vectors of ANS introductions, including intentional and unintentional, into the Great Lakes and determine the relative risk of each vector. Develop an action plan to prioritize and prevent ANS introductions from all vectors with set implementation deadlines. Develop mandatory federal enforcement programs for implementation of the action plan insuring provisions for citizen suit. Set criteria and standards for ballast water treatment and management that are subject to guaranteed periodic review and revision and that effectively reduce transfers of invasive organisms into and within the Great Lakes. Create and implement a thorough and effective screening process to ensure all policies, treatments and technologies are environmentally sound (as defined in the National Invasive Species Act).
