The dairy facility required a dairy nutrient management plan completed and improvements made within 6 months of start of operations (in November for us). Our conservation district should have taken care of this, working with WSDA, but after many emails, we just built it without a plan, with verbal approval from our WSDA person. Thank you DAD! This went so smoothly. We tied the facility into this, and let the storm water go further down the hill into rock.
