EXECUTIVE SUMMARY

Gulf SRC Company Limited (“GSRC” or the “Owner”) is developing Gulf SRC 2,500 megawatt (“MW”) Combined Cycle Power Plant (“CCPP”) project in Hemaraj Easter Seaboard Industrial Estate (“HESIE”), Sriracha District, Chonburi Province, approximately 140 km east of Bangkok. Natural Gas will be transported to GSRC through a new 2.5 km long gas pipeline (“Interconnecting Pipeline”). EGAT will build a new 10.9 km overhead transmission line to connect GSRC’s switchyard with EGAT’s Pluak Daeng Substation. Raw water to GSRC will be supplied by East Water via the Hemaraj Raw Water Pipeline. This is the seventh Quarterly Environmental & Social (“E&S”) Monitoring Report of AFRY (the Lenders Technical Advisor) and covers the period from July 1st, 2020 to September 30th, 2020. AFRY would like to thank the Owners and EPC Contractor for their valuable support during the site visit and for providing the documentation requested to prepare this report.

Health and Safety

The key OHS statistics for the construction monitoring period are 2,458,371 safe man hours accumulated for the Power Plant Area/Raw Water Pond Area and 109,107 safe man hours accumulated for the Interconnecting Pipeline. There were 6 HSE incidents for the Power Plant Area/ Raw Water Pond Area and 1 HSE incident for the Interconnecting Pipeline. A fatality did occur at the Project site on August 19th, 2020 during transformer assembly construction at Block#2. The fatality has not been reported as a Project fatality or as a Lost Time Incident due to the incident occurring to a 4th tier contractor of Sino-Thai. Contractors past the 2nd tier contractors to Sino-Thai are not covered under the requirements of the Project HSE Management Plan and therefore incident reporting. The fatality is regarded as a Significant Safeguard and Social Reporting Event according to the Common Terms Agreement (clause 18.44) and the Owner has carried out the appropriate actions required by the Common Terms Agreement. High risk activities are now being identified for all Contractors of Sino-Thai past the 2nd tier contractor and are subject to Job Safety Analysis (JSA) if the activity needs to be performed onsite. In response to the fatality the LTA recommends the following additional measures: • Accident/incident reporting procedure is also updated to reflect the findings of the fatality and to ensure all accident/incidents which occur to contractors past the 2nd tier contractor of Sino-Thai (based on the high risk activities identified) are now separately reported and included in the EPC Contractor monthly reports; and • The high risk activities are reviewed in the weekly EHS meetings and those activities are supervised by the EHS personnel of the EPC Contractor.

Labour and Working Conditions and Security

The number of workforce personnel as of September 25th, 2020 is 2,919. Welfare facilities at the Project site including rest shelters, toilet/bathroom facilities, drinking water stations and medical facilities which continue to be adequately managed. Hygiene/cleanliness and the welfare facilities at the workers camp also continue to be adequately managed. In general, the hygiene/cleanliness of the workers camp was observed to be adequate in Zones 1, 2 and 3 of the workers camp. However, in the Myanmar workers zone a number of room doors were observed to be damaged.

Stakeholder Engagement

During this construction monitoring period, two education activities were undertaken on September 16th, 2020 and September 24th, 2020 to pass on knowledge to local community members concerning the power plant commissioning activities. The activities were undertaken to comply with Project requirements of undertaking 2 education awareness events per year for local community members.

Environmental and Social Monitoring

The EHS capacity recorded for this construction monitoring period and the training undertaken is considered to be sufficient. The Owner and Contractor continue to implement specific HSE procedures and programs for the Power Plant and Interconnecting Pipeline, this includes implementing COVID-19 prevention methods. It is AFRY’s opinion that the Project was operating in compliance with most of the Project E&S requirements during the construction monitoring period. Corrective actions have been identified concerned with housekeeping/material storage, hazardous waste storage, repairing damage to room doors at the workers camp (Myanmar workers zone), updating HSE procedures for Accident/Incident Reporting, Lifting Rigging and Chemical Handling Safety and knowledge sharing to local communities concerned with the Projects operation.

2.3 Fatalities

A fatality occurred at the Project site on 19th August, 2020 during transformer assembly construction at Block#2. A 25 ton crane was being used for transformer assembly. During tire maintenance of the crane, the crane tire was being filled with air. During this process the tire ring blow out striking the maintenance person on the head. The cause of the incident is reported to be inappropriate installation of the lock ring on the tire or over pressure during filling the tire with air. The maintenance worker was taken to Pluak Daeng Hospital by Sino-Thai emergency vehicle, accompanied by the site nurse. On arrival at the hospital the worker was pronounced dead due to the head injuries sustained. The crane was supplied by a 3rd tier contractor to Sino-Thai and maintenance activities for the crane tire were being undertaken by a 4th tier contractor to Sino- Thai (the EPC Contractor). The deceased worker was the employee of the 4th tier contractor to Sino-Thai. Financial support to the deceased persons family was provided by the Owner, Sino- Thai and Sino-Thai’s 1st tier contractor in addition to the social security program under Thai Law. The fatality has not been reported as a Project fatality or as a Lost Time Incident due to the incident occurring to a 4th tier contractor of Sino-Thai. Contractors past the 2nd tier contractors to

2.6 Low Risk Issues

The following low risk issues concerning health and safety have been identified for this construction monitoring period: • The construction access road at the front of each Power Block is particularly congested with movement of vehicles and workers between each of the Power Blocks under construction. Heavy equipment is parked in this area which was not being used and some poor housekeeping was observed in terms of storage of materials which made the area more difficult to navigate for workers (Refer to Photo 1 in Appendix 1). • There was a lack of space in the hazardous waste storage area for further used oil storage. Used oil storage containers are being stored inappropriately which could result in spillages (Refer to Photo 2 in Appendix 1).

5.4 Compliance with EHS National Laws and Regulations

The Projects compliance with the EHS National Laws and Regulations specified in the ESIA/EMP dated October 2018 are provided in this section.

5.4.1 Construction Environmental Monitoring

The Project continues to implement the environmental monitoring program as per the requirements of the ESIA/EMP dated October 2018. The environmental monitoring undertaken by the Owner is predominately for the 6 monthly report of environmental monitoring required by ONEP. The draft report for January to June 2020 was submitted to ONEP on July 15th, 2020 and final report on the July 21st, 2020.

5.4.2 Ambient Air Quality

During construction, the Project is required to undertake ambient air quality monitoring at 5 locations every 6 months (twice per year) for a period of 7 consecutive days. Parameters monitored are Total Suspended Particulates (TSP), Particulate Mater 10 (PM10), Nitrogen Dioxide (NO2) and Sulphur Dioxide (SO2). There was no ambient air quality monitoring required for ONEP during July to September 2020, and the next round of ambient air quality monitoring for ONEP is scheduled for November 2020. The Owner engaged Geo-Informatics and Space Technology Development Agency (GISTDA) to provide data to support the study to monitor the potential impacts at the location of the predicted maximum NO2 ambient air quality concentration (refer to Figure 5-1) from the Projects operation as determined by the environmental impact studies. This initial data was collected prior to the commissioning of Block#1 in order for the existing conditions at the location to be understood in order for changes to be monitored during the Project operation.

Date 10 November 2020, Revision 0

Lenders’ Technical Advisor Quarterly Environmental and Social (E&S) Monitoring Report No. 7

Page 41

Figure 5-1 Location of Predicted Maximum NO2 Concentration

This initial study comprised of obtaining satellite imagery and undertaking a land use survey which covered an area of 5 x 5 km2 from the location of the predicted maximum ambient air quality concentration. From the data obtained the location of concern is classified as forest habitat comprising of dry evergreen forest and mixed deciduous forest. The forest canopy density was to be found in the range of 70-80%. The Project plans to review satellite imagery on an annual basis for any change to the land use classification and forest canopy density. The LTA notes that any change could also be due to external influences and not directly from the Project and as such will require consideration alongside the Projects actual emissions to be monitored by the Projects continuous emissions monitoring system. 5.4.3 Noise

During construction, the Project is required to undertake noise monitoring at 3 locations every 6 months for a period of 7 consecutive days. There was no noise monitoring required for ONEP during July to September 2020, and the next round of noise monitoring for ONEP is scheduled for November 2020. However, during steam blowing at Block#1, STECON have undertaken spot noise measurements using a hand held noise meter to record noise levels at different locations at the Project site and at sensitive receptors to provide an indication of noise levels during steam blowing. The results of the noise monitoring for the steam blowing activities undertaken on October 14th, 2020 and October 15th, 2020 are shown in Table 5-8and monitoring locations are shown in Figure 5-2. A background noise level was also recorded at the sensitive receptor locations before steam blowing commenced in order for a comparison to be made. The noise monitoring results show no exceedances of the Community Noise National Standard at the sensitive receptors and no significant difference compared to the background noise measurement before steam blowing. Based on these results it can be concluded that the installed noise barriers are performing effectively to date but this is based on spot noise measurements only and further monitoring is expected during steam blowing.
