INTRODUCTION AND SUMMARY In 2013, Azusa completed 20 circuit patrols, 372 detailed inspections, 0 intrusive wood pole inspections, and 140 corrective actions on facilities subject to G.O. 165. This report includes Attachment A, a table containing summary data of Azusa's compliance activities for 2013 presented on a system wide basis. II. BACKGROUND The California Public Utility Commission adopted G.O. 165, which established minimum inspection requirements for certain electric distribution facilities (including maximum allowable inspection cycle lengths), condition rating, and recordkeeping and reporting on scheduling and performance of corrective action. G.O. 165 imposed the following reporting requirements: Each utility shall complete an annual report detailing its compliance with the general order. These reports will include the utility's plans for the types of inspections and equipment to be inspected during the coming year. The report shall identify the number of facilities, by type, which have been UB-144 inspected during the previous period. It shall identify those facilities which were scheduled for inspection but which were not inspected according to schedule and shall explain why the inspections were not conducted, and a date certain by which the required inspection will occur. The report shall also present the total and percentage breakdown of equipment rated at each condition rating level, including that equipment determined to be in need of corrective action. Where corrective action was scheduled during the reporting period, the report will present the total and percentage of equipment which was and was not corrected during the reporting period. For the latter, an explanation will be provided, including a date certain by which required corrective action will occur. The report will also present totals and the percentage of equipment in need of corrective action, but with a schedule date beyond the reporting period, classified by the amount of time remaining before the scheduled action. All of the above required information shall be presented for each type of identified facility. UB-1245 III. SUMMARY OF AZUSA LIGHT & WATER'S INSPECTIONS AND CORRECTIVE ACTION ACTIVITIES DURING CALENDAR YEAR 2013 G.O. 165 requires annual inspection performance data, condition ratings, and corrective action information. The following is a narrative summary of the required data. In addition, Attachment A contains a tabular summary of data. A.

Azusa actually completed 155 underground and pad mounted equipment detailed inspections. This amounts to 33% of Underground and 20% of Padmount system devices. C. Condition Ratings G.O. 165 requires Azusa to rate the condition of specified equipment such as, (transformers, switches, regulators, capacitors and conductors). Under Azusa's condition rating system, established in 2001, revised in 2004, condition rated 1 equipment and structure repairs are made immediately. Azusa plans ahead for condition rated 2 &3 repairs. Condition rating 4 is used for all equipment whose condition either does not require any repair or does not require any scheduled repair. As of 12/24/2013, Azusa's condition rating system included 0 facilities with Level 1 condition ratings, 0 facilities with Level 2 condition ratings and 3 facilities with Level 3 condition ratings.

INTRODUCTION Pursuant to General Order 174 and in compliance to the safety order, Azusa Light & Water established in early 2013 a monthly schedule for performing inspections inside City owned electrical substations/facilities. Inspections are performed by designated qualified personnel of Azusa Light & Water and their findings are recorded in a checklist format used during these inspections. Azusa Light & Water currently owns and operate only two (2) electrical substations in the City. Both of these substations are jointly operated with another investor owned utility, which operates their own portion of switching facilities inside these substations. For calendar year 2013, Azusa Light & Water followed an inspection program performed by qualified personnel and the results were recorded and retained. Azusa complied with GO 174 by completing monthly inspections of the two City of Azusa owned electrical substations/facilities located within Azusa's electric service territory. Based on the substation inspections, there were two (2) URGENT ratings that were recorded which required immediate corrective action. There were three (3) TIMELY ratings which require UB-x'52 corrective action within 6 months, were recorded and duly corrected. There was one (1) NON EMERGENCY rating, which requires corrective action in two (2) years was recorded, and that the recommended correction is pending in this one substation which is subject to G.O. 174. IL BACKGROUND The California Public Utility Commission adopted G.O. 174, which established inspection and reporting requirements for electric substations. These requirements are set forth under Section 3 and Section 4 of the GO 174 as adopted on 25 October 2012 under CPUC Decision 12-10-029. A copy of the GO 174 is included in this report for reference. IIh SUMMARY OF INSPECTIONS AND CORRECTIVE ACTION ACTIVITIES DURING CALENDAR YEAR 2013 G.O. 174 requires the governing utility to identify, set a condition rating standard (where applicable), and categorize the inspection for all distribution substation within the utility's jurisdiction. The condition ratings and time for corrective action was established by Azusa Light & Water for performing inspection and assessment on the condition of specified substation equipment such as, (transformers, switches, regulators, capacitors, relays, batteries, A/C units and conductors etc.). Under Azusa's condition UB-1453 rating system, a condition rated "Level 1" requires equipment and structure repairs are performed or made immediately. Azusa plans ahead for needed repairs under conditions rated "Levels 2" & "3". Condition rating "Level 4" is used for all equipment whose condition either does not require any repair or does not require any scheduled repair. As of 12/24/ 2013 and after completing the monthly scheduled inspection for the reporting period, Azusa's condition rating system included two (2) facilities/equipment with Level 1 condition ratings. The blown cap bank fuse at Kirkwall Substation was immediately replaced and also a DC battery bank that showed imminent failure was immediately replaced with new batteries. Also, three (3) identified facilities/equipment with Level 2 condition ratings, were all corrected. These corrections included replacement of control relay for cap bank at Kirkwall Substation, installation of bird guard at Azusa Substation CB bushings, and restoration of internal telephone extension line in the control room at Azusa Substation. There was one (1) facility/equipment with Level 3 condition rating which entailed replacement of one of the security camera lens at Kirkwall Sub. All other remaining facilities subject to condition rating were rated at Level 4. IV.
