Flood Emergency Impact Prevention Plan

The Company develops a Business Continuity Plan (BCP) to prevent and manage potential business impacts arising from flood emergencies and reduce risks to its projects. Measures include constructing embankments or flood barriers around wastewater treatment ponds to prevent flooding and wastewater leakage.

In addition, the Company continuously inspects and maintains drainage systems to prevent blockages and reduce the risk of chemicals or hazardous waste contaminating the environment. Chemical products, raw materials, and waste are also stored in areas protected from flooding to prevent environmental impacts during emergencies. The Company also inspects and improves operational areas with a history of flooding and surveys potential routes through which water may enter project sites, enabling flood protection systems to be designed and upgraded effectively according to the specific characteristics of each project.

Note: Tier levels are determined based on each project’s elevation above sea level and the geographical characteristics of its location.

Examples of Flood Prevention and Management Plans for the Company’s Projects

	Water Level (meters)	Floodgate Level (meters)	Prevention Measures	Actions
Tier 3	6.1	6.1	Inspect flood embankments daily. Operate water pumps and prepare reserve fuel.	Evacuate non-essential personnel from the area. Assign personnel to maintain 24-hour surveillance. Place sandbags around the project site.
Tier 2	4.4	5.8	Prepare emergency equipment, such as power generators, boats, and supplies. Prepare sandbags to block entrances to the project site.	Establish temporary access routes to and from the project site. Disconnect and relocate critical equipment.
Tier 1	2.4	3.8	Monitor water conditions around the project site. Monitor the management of nearby dams or reservoirs. Coordinate with government agencies to obtain relevant information and policy plans.	Inspect and maintain water pumps in operational condition by conducting test runs at least once a week. Avoid bringing electrical equipment, such as solar panels, inverters, and transformers, into flood-prone areas.
