4. Summary of Updates Changed measure category to “Small Saver” – Professional judgment is used – Recent regional program savings estimated at 1.0 – 1.5 aMW per year. Incorporated data from recent studies: – Idaho field study (Neibling) – PacifiCorp program data (2006-2008; 2009-2011) – Most recent Farm and Ranch Survey Measure Additions/Changes – Added a new measure: Tower Gaskets. – Combined the existing Nozzle measure, Low Pressure Regulator measure, and sprinkler head measures (5) into a new “sprinkler package” measure. – Changed measure specification to require the following components to be leaking: Wheel/hand line: Impact Sprinkler, Gasket, Drain, Hub, Leveler (also malfunctioning) Pivot/Linear move: Pivot boot gasket, (Tower gasket, too) Reviewed these updates and all other inputs with subcommittee and made some edits, with consensus. 4
