(d) The owner shall prepare the emergency action plan using guidelines provided by the executive director or using a format approved by the executive director before the plan is prepared. If an owner owns more than one dam, the owner shall prepare a plan, with timelines, for preparing emergency action plans based on priority determined by hazard and submit the plan to the executive director for review. If an owner cannot complete the emergency action plan within the two years required in subsection (b) of this section, the owner shall request an extension of time showing cause or a reasonable basis for the need for an extension and providing a time frame to complete. The request shall be submitted to the executive director for review and approval. (e) The executive director shall review the emergency action plan and provide any comments in writing to the owner. (f) The executive director shall file the emergency action plan in the agency's confidential, permanent records. (g) The owner shall review the emergency action plan annually, update the emergency action plan as necessary, and submit a copy of the updated portions of the emergency action plan to the executive director annually beginning three years after the effective date of this section. If the emergency action plan was reviewed by the owner and no updates were necessary, the owner shall submit written notification to the executive director that no updates to the emergency action plan have been adopted or implemented. (h) The owner shall perform a table top exercise of the emergency action plan on the frequency provided in the owner's emergency action plan, or at least every five years.
