5. History of the Groundwater Change Policy • In 2007 we were inundated with cross valley change application filings • Meeting were held on: • August 28, 2007 S.E. expressed concern that moving multiple paper rights to the East side of the valley could cause future interference issues. • April 24, 2008 to propose a change application policy be implemented • Comments were submitted pursuant to the meeting • July 22, 2008 to implement the policy. • Effective date of policy April 16, 2008 Surveying principles

9. Tooele Valley Groundwater Change Application Policy • Policy Summary • Can’t Cross Into Eastern Zone • Buffer 3 Miles East Perpendicular to Flow Path • Change App. Specifics • Multiple Water Rights • Each Water Right Will Be Evaluated Individually • Most Restrictive Water Right Will Govern • Multiple Points of Diversion • Based On Eastern Most Well • Applications Will Still Be Considered On Their Own Merit Surveying principles

11. Understanding the Tooele Valley Groundwater Change Application Policy • What the policy does: • Creates some semblance of order and certainty • Allows WR holders to predict outcome before filing • Allows the S.E. to make more timely decisions on change application • Protects the East side from further over- appropriation • Stops future interference issues Surveying principles

12. Understanding the Tooele Valley Groundwater Change Application Policy • What the policy does not: • It does not “divide” the valley into 3 sections • The SE continues to administer the valley as one hydrologic system • It is not the “end all” answer when considering change applications • Each application is considered on its own merits Surveying principles
