The EQ basin is exhibiting some extensive corrosion in areas but plan is to address this when other upgrades are done in near future like new headworks for screening & grit removal. County hasn't been checking on irrigation storage pond levels, postings, nor postings & educational materials at golf clubhouse/pro shop. For some reason, all reference to storage pond was omitted from last renewal along with all its requirements like maintaining at least 2 feet of freeboard. However, this is still a requirement and County needs to be aware when its less than 2 feet so it can make a decision to reduce or cease transfer to pond or to initiate whatever mechanism it has in its agreement with golf course owner to irrigate more to bring down level including temporary closure of one or more courses. Freeboard was observed to be about 16 inches, but needs better marker installed. Signage observed along pond at tee box near irrigation pump station found to read 'Reclaimed Water -Do Not Drink" which isn't really appropriate since that is for distribition purposes through plumbing fixtures. They should be along the lines of "Pond Contains Reclaimed Wastewater -Avoid Contact" and signage at clubhouse/pro shop to read along lines of "Golf Course Uses Reclaimed Wastewater for Irrigation - Obtain Educational Pamphlet for More Info". County needs to be aware of the golf course owner's plans to develop areas adjacent to courses and confirm the activity will not result in conflicts with required buffers or setbacks. A review of spray irrigation records indicates that Ernie that does the irrigation on the course, but he is not listed as being designated as a SI operator. Donald Dixon is still listed from 2013 as only one.
