This is testament to the efficiency of our air pollution management targeting SOx, NOx, and TSP. • Management of Volatile Organic Compounds (VOCs) IRPC started a project to upgrade the Reformate tank roofing at the storage tank yard. Under the project, to be completed in the first half of 2022, existing cone roof tanks were being replaced with internal floating roofs. The project aims to reduce VOC emissions by 90%, compared to before the improvement. Actions are being taken to control, and prevent VOC discharge during maintenance work, using the Green Turnaround concept aimed at assessing risk of VOC discharge associated with various maintenance activities to find appropriate measures to prevent it. Measurements will be taken at the facility prior to maintenance disassembly, and surveillance measures taken around the factory perimeter walls to verify outcomes of preventive measures as well as to analyze and identify any source of significant discharge. This is in order to find sustainable solution to the problem. IRPC collaborated with the public sector to provide information to draft a standardized code of practice (COP) on the prevention of volatile organic compound emissions from three major sources: storage tanks, flare stacks, and from maintenance works. The Company also extended cooperation to others within the same industrial sector to promote adapting the draft COP in actual operations in a move towards finding a sustainable solution to VOC management problems. Water Management Water is a vitally important resource, not only for IRPC but for everybody else in all sectors of the society. The company takes it upon itself to participate in water resource management in collaboration with government agencies and other water users within the PTT Group as well as external parties. Participation in water resource management must start at the upstream to ensure the company’s operations do not interfere with water consumption patterns linked to ways of life of people in the agricultural sector, the needs of industrial sectors and the general public. In 2022, a water user committee was established with the objective to achieve a balanced approach to the sharing of natural water resources between IRPC and communities. This is implemented alongside the company’s effort to ensure smooth, continuous operations, uninterrupted by scarcity or shortage. IRPC’s internal water resource management approach is based on the 3Rs concept: reduce, reuse, and recycle. That is, reduce water consumption at the source, then reuse and recycle industrial discharge that has undergone treatment to meet quality standards suitable for reuse for other purposes, such as watering plants and using treated water instead of distilled water to prepare chemical solutions. As for digitalization, the i-utility application is being used to monitor and compare water consumption against efficient usage to promote awareness. This could lead to less water being extracted from the sources in the first place. The company also launched a campaign to encourage employees to conserve water in their daily life at home and at work as part of the effort to instill in them a culture of water conservation. 152 IRPC PUBLIC COMPANY LIMITED 56-1 ONE REPORT 2021
