11. Education  Need to understand flow of nutrients through livestock production system  Need to apply principle of mass balance, i.e. they may change chemical form, but end up somewhere  Need good science to track nutrients through production system  Need to understand the tradeoffs and/or impacts of alternative production systems  Need to quantify benefits of BMPs

12. Dialogue  Internal Ag Team  Other State Agencies Dept. of Ag, NRCS, Extension  U.S. Environmental Protection Agency  Other States  Producers  Stakeholders

13. Partnering  Projects  Collaboration  Listening  Learning  Innovation

14. Summarizing the State’s Perspective  Air quality regulations are coming  We all need to educate ourselves  Proactive strategies will help  Learn from the past  Communicate  Innovate
