AZUSA LIGHT & WATER DEPARTMENT'S ANNUAL REPORT
PURSUANT TO GENERAL ORDER NO. 165
I.
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.

condition rated 1 equipment and structure repairs are made immediately.
Azusa plans ahead for condition rated 2 &3 repairs. Condition rating 4 is

AZUSA LIGHT & WATER
2013 ANNUAL REPORT - GENERAL ORDER NO.174
I. 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.
