This interactive form allows customers to submit their compliance with State recycled water requirements every quarter. • Self-monitoring report questions were modeled from examples and input staff obtained from other California agencies serving recycled water. The compliance requirements are not new, and the questions asked on the form are similar to questions asked and observations made in person inspections performed by CSO. • Central San's website was updated with the new reporting requirements including a link to the new reporting form. 6 CENTRALSAN 3 September 13, 2021 REEP Committee Meeting Agenda Packet- Page 32 of 43 Page 5 of 7 SELF-MONITORING QUARTERLY REPORT FORM Quarter 2:April 1,2021-June 30"20Z 1 nr,a.wr a.mm«..wn m�rc•vr M«..P.n.•.w'.min e.._.a wr m-m.. 1-ppo the r,rr• s.-itmenwmhewuon e�l metered site: w<.ue.a.w•e.rr.nrrm•r�..m�o<.a.r 29id yo.r ol•se recycled water,unolt from the site?

Staff follow-up via email and phone calls to customers as-needed to ensure full compliance is met. • Site visits will be conducted as-needed if the customer doesn't report after multiple reminders or if the customer has special requirements (e.g., replacement signs, address major leaks, etc.).
