Elk River Municipal Utilities UTILITIES COMMISSION MEETING TO: FROM: ERMU Commission Mike Tietz—Technical Services Superintendent MEETING DATE: AGENDA ITEM NUMBER: July 9, 2019 6.1d SUBJECT: Staff Update ACTION REQUESTED: None DISCUSSION: • In May, the locating department had a total of 520 locate tickets consisting of 10 emergency tickets, 8 cancellations, 447 normal tickets, and 44 updated tickets. This is an 18% decrease in volume of tickets from the previous month. • Electrical Technicians continue with updating the power bill, substation checks, disconnects/reconnects, dealing with customer meter and off-peak issues, as well as the new installation of the solar facility at City Hall. • On June 20, staff ran Engines 3 & 4 without any issues. Engines 1 & 2 were run on June 21. The previous issue with Engines 1 & 2 was determined to be water in the fuel system. The water was removed from the day tank and fuel lines to both engines. We are still trying to determine the source of the water in the tank. • Staff continues to perform meter audits around the system as time allows. • Mapping department continues to update points and attributes for all of our systems assets within the ESRI ArcView GIS system. • On June 21, a squirrel caused a fault that opened the high-side circuit breaker at the Otsego Substation, resulting in an outage for 1215 customers. Staff took an oil sample from the power transformer for a rush dissolved gas analysis to make sure that the transformer did not sustain any internal damage from the fault. Staff is investigating how the squirrel made entry. • Staff replaced a failing 69 kV circuit switcher interrupter on the center phase of Waco Bank 1 Substation. • Members of the leadership team are reviewing the Disaster Recovery Plan and gathering various RP3 application criteria for the upcoming designation renewal.
