This indicates a trip function where the breaker trips based on the square of the current (12) multiplied by time (t), meaning the longer the current flows, the more energy is generated, and trips the breaker to prevent damage. The motor, bowl, and cable have been inspected at Layne's Aurora Yard, while the pipe and threads are being inspected by a third party who specializes in the rehabilitation of 8 round threads of which Well 9's pipe is threaded to. Please find the City of Yorkville Well 9's Pump Inspection Report ("PIR") attached.

Top of castings, typ. caused by heat, wl grooves & minor wear BOWL ASSEMBLY OBSERVATIONS All castings and impellers are in good condition. Upper volute of castings have minor erosion near ring area. The pump contains bronze wear rings that show signs of wear, including significant grooves suggesting a foreign object has gone through the assembly. The wear rings are "buffed" as if the well was producing sand, which the City noted this well was not known to produce sand. A couple of impellers showed signs of discoloration that could potentially indicate heating up. Impeller shaft, strainer, and collets were noted as "ok for reuse." The top case discharge flange will need to have the remaining pipe machined out as it was stuck when pulling the pump and needed to be cut. Indications of a foreign object causing grooves in the impeller ring and wear ring. Evidence a couple of impellers heated up at some point. However, no direct evidence for high amps 1 12T electrical trip being caused from the bowl assembly. See attached Bowl Assembly Inspection Report Layne A GRAnrrE COMPANY 721 WEST ILLINOIS AVE. AURORA, IL 60506 630.897.6941 PHONE City of Yorkville WELL NO. 9 INSPECTION REPORT BOWL ASSEMBLY RECOMMENDATIONS Layne recommends reapplying ceramic coating to the upper volutes of castings as well as reapplication of ceramic coating on all interior components of the pumping assembly due to minor wear. True up the impellers, including deburrlpolish collet bores. All bronze wear rings should be replaced due to their condition and wear. Straighten and polish impeller shaft (typical rehab for bowl service). Deburr and polish all collets. Replace suction bushings. Repair top case flange and replace pipe. Typ. Bowl servicing.

Interior pipe in good condition, no signs Heated coupling to break loose, Upper surge check valve, to be of erosion/corrosion, t damaged threads. replaced COLUMN PIPE OBSERVATIONS The condition of the pipe is generally good in terms of the historical erosion/corrosion seen in "fishing" jobs from 2009 and 2017. This can be contributed to the sacrificial zinc sleeves applied as well as threading all pipe to S round ("8 RNY) in 2017. Silicon was applied to the threads to further help prevent erosion and corrosion. Some pieces of pipe wouid not come loose with the utilization of power tongs, therefore, some joints needed to be cut. No evidence of high amps 1 12T electrical trip being caused from the column assembly. Lare A GRAMTE COMPANY 721 WEST ILLINOIS AVE. AURORA, IL 60506 630.897.6941 PHONE City of Yorkville WELL NO. 9 INSPECTION REPORT COLUMN PIPE RECOMMENDATIONS Layne provided the City with a worst case scenario if all pipe needed to be cut, rethread, and new pipe for a not to exceed case budget. New surge check valves were included in this quote as historically, this has been where the column assembly has failed for Well 9. Layne recommends replacing any lost zinc sleeving due to pipe rehabilitation as well as installing the column assembly to the same specs. as it was installed in 2017. Once final inspection is completed by third party, Layne will update the city on necessary repairs and/or replacements. CABLE OBSERVATIONS The cable and flat cable were in good condition. Hypot testing of the full cable assembly showed minimal leakage. Field crew noted that the flat cable looked "thin" in some places. J. Geltz, J. Balluff, and J. Gray inspected the flat cable closely and did not note any "thin" spots. Cable was reconnected to motor in shop and ohms testing was conducted while all potential weak points were wet. No continuity issues were recorded during test. No evidence of high amps / 12T electrical trip being caused from the cable assembly. CABLE RECOMMENDATIONS Cable and flat cable ok for reuse. see attached hypot test report) WELL OBSERVATIONS Unremarkable WO head. Total depth was recorded with a wireline to 1359'. Original depth on record is 1368', suggesting 9' of back fill. WELL RECOMMENDATIONS Layne recommends televising the well while the pump is removed to visually inspect the Well's condition.

Upper volute of castings has erosion near ring area and will need an application of ceramic coating. Recommend re -application of ceramic coating on all interior parts that will need it when pump is blasted. Pump contains bronze wear rings and due to their condition and wear, they will need to be replaced. Note that this pump is set up for use with 17" motor and 10" discharge. The top case discharge flange will need to have the remaining pipe machined out of it.

Leakage values are quite low and cable appears suitable for reuse. However, note that reinstallation means cable as tested on spool above ground will be flexed over cable sheaves, squeezed against pipe by stainless steel banding and will be subject to possible down -hole damage, as well as significant hydrostatic pressure. Hypot testing may not detect leakage to atmosphere. (i.e. external holes in cable insulation). Witness: Signature: John Geltz WATER RESOURCES 721 W.
