Substructures inspection, assessment and action plan The Inspection and Maintenance group performed visual inspection of overhead and underground facilities within LAX area during the past 12 month. Underground inspections were limited due to accessibility to runway/taxiway/CTA area. A total of 840 overhead and underground facilities were inspected between 7/1/17 and 6/30/18. See Attachment 2 for detailsand completion dates.________________________________________________The EPRI (Electric Power Research Institute )report recommends moving forward with RS-X.

Visual inspections of overhead facilities are on a 12 month cycle, limited underground visual inspection due to accessibility. Detailed inspections are on a 3-year cycle for underground facilities and five-year cycle for overhead facilities.

JmmedjateActjonscurrentjyjnprogresS-Update LAX Airport Response Coordination Center emergency communication protocol On Feb 26, 2019, managers of both sides met and discussed a need for a proper communication protocol .

LADWP is updating their ONP (Outage Notification Protocol) software to include LAWA's designated email addresses.

LADWP to convey proper communication protocol to LAWA.1

Formalize the communication protocol in writing.Both

LAWA and LADWP are working to update a spreadsheet to identify all industrial stations on the LAX and VNY footprints.

Plan for follow-up meeting in August 2019.

Ensure continued monthly testing and exercise of all back-up generators & uninterruptable power supplies (UPS)

LAWA excercise generators monthly as part of their maintenance program. LAWA has an on-going maintenance contract to test Uninterruptable Power Supplies (UPS) quarterly. Facilities Maintenance and Utilities Group is setting Up Maximo to access test reports.

Generator testing is continuing on a monthly basis. UPS units and inverter units are tested and batteries inspected on a quarterly basis. Any defect found with applicable systems is repaired as soon as practical.

The matters is being reviewed by both departments general counsel. this Interconnection Agreement for the CUP (Central Utility Plant) will facilitate methods of operating the CUP in islanding mode.

Both agencies BIRDI and NREL will provide scope of Work to LAWA to generate a task order to enable the CUP cogeneration islanding. Cogeneration Islanding will enable the CUP to continue operation during a power outage.
