DocuSign Envelope ID:098B7080-775F-4220-9432-FB15222455EA EAP for Lake Orange Dam, ORANG-005 SUMMARY OF EAP PROCESS There are four steps that must be followed anytime an unusual or emergency event is detected at Lake Orange Dam. The steps are: Step 1 - Event Detection and Level Determination During the initial step, an unusual event or emergency event is detected at the dam and classified by Christopher Sandt into one of the following event levels: Event Level 1, RED: Urgent!! Emergency Event; Dam failure imminent or is in progress Event Level 2, YELLOW: Emergency Event; Potential dam failure situation; Rapidly developing Event Level 3, GREEN: Unusual Event; Slowly developing Step 2 - Notification and Communication After the event level has been determined, notifications are made in accordance with the appropriate notification flow chart provided in STEP 2 of this EAP. Step 3 - Expected Actions After the initial notifications are made, Christopher Sandt should refer to Table 3.1 and confer with Johnny Waycaster to develop and execute appropriate preventative actions. During this step of the EAP, there is a continuous process of taking actions, assessing the status of the situations, and keeping others informed through communication channels established during the initial notifications. The EAP may go through multiple event levels during Steps 2 and 3 as the situation either improves or worsens. Step 4 - Termination and Follow-up Once the event has ended or been resolved, termination and follow-up procedures should be followed as outlined in Section 4 of this EAP. EAP operations can only be terminated after completing operations under Event Level 3 or 1. If Event Level 2 is declared, the operations must be designated Event Level 3 or 1 before terminating the EAP operations. 4 Revision No: 1(July 2018) March, 2015
