21 STAFF S FIRST REQUEST FOR INFORMATION QUESTION NO. 1.8 Describe the Company s distribution system inspection policy including but not limited to inspection intervals and types of inspections performed. RESPONSE: Mon Power performs the following types of inspections: Distribution pole inspections: Mon Power performs an inspection of poles on a 12 year cycle. During these inspections, the pole inspectors also not any line issues requiring immediate attention and these items are scheduled for repair as soon as possible. The Core Substation/#l Cassville circuit had pole inspection in The Guston Run- Hagans #I27 23kV line feeding Core Substation had pole inspection in Capacitor inspections: Mon Power performs capacitor inspections on an annual basis. This circuit does not have any line capacitors installed therefore no line capacitor inspections have been performed on this circuit. Recloser readinqs: Mon Power performs recloser counter readings on an annual basis. This circuit does not have any line reclosers installed, therefore no recloser inspections have been performed on this circuit. Circtiit inspections: Mon Power inspects all or parts of circuits when warranted due to performance issues, such as high number of customer interruptions due to problems on a segment of distribution line, or other conditions that would prompt a field visit to the circuit. Veqetation Manaaement: Mon Power routinely performs extensive vegetation management activities on its circuits. Vegetation activities are managed to achieve cycle clearance which includes the removal of selected incompatible vegetation within the clearing zone corridor, removal of limbs overhanging the clearing zone corridor, and removal of hazard trees that are dead, dying, diseased, and leaning or significantly encroaching the corridor. The #I Cassville Circuit was last trimmed in 2014 and is scheduled to be trimmed again in See response to 1.7 for all maintenance performed on this circuit in the past 5 years

22 STAFF S FIRST REQUEST FOR INFORMATION QUESTION NO. 1.9 Please provide details of all inspections and repairs performed for this circuit in the past five years. RESPONSE:. See response to 1.7 and 1.8 for all inspections and repairs performed on this circuit in the past five years. 12

23 STAFF S FIRST REQUEST FOR INFORMATION QUESTION NO Provide a description of the investigation conducted by Mon Power determining an electric insulator failed (Answer, page 2, Item 3). RESPONSE: On Wednesday, February 4,2015, customers on the #I Cassville Circuit experienced an interruption in service. Crews at the scene determined that a 27 kv disconnect on a 23 kv line had failed. The 27 kv disconnect broke in two at the attachment point in the middle of the porcelain insulator. This caused the energized portion of 23 kv line to fall into the 12.5 kv distribution line located directly below. The breaker on the 23 kv line detected the fault and opened, which de-energized the line. 13

24 STAFF S FIRST REQUEST FOR INFORMATION QUESTION NO. 1.I 1 Please indicate on the Diagram provided in Data Request 1.I, the location of the pole on which the insulator failed (Answer, page 2, Item 3). RESPONSE: - See Exhibit for the location of the pole that experienced the insulator failure. 14
