1 EXECUTIVE SUMMARY

1. This environmental monitoring report covers the implementation of environmental management plan (EMP) of the nine subprojects funded in the Tranche III of Multi-Funding Facilities (MFF) in the period of 2019 Q4 (from October to December).

2. Brief subproject construction status. As of 31 December 2019, all nine subprojects under the ADB tranche III of MFF had been under operation and construction. SPMB manages seven subprojects, five of which that are the extension of substation subprojects had been put into operation with the full capacities at the different times: 220kV Tra Vinh energized in December 2017, 220kV Vung Tau and Duc Hoa in March 2018, 220kV Uyen Hung in April 2018, and 500kV Cau Bong in May 2019. The two other subprojects 500 kV My Tho – Duc Hoa transmission line (TL) and Duc Hoa 500 kV substation with its connections were under construction. The construction of the subproject 500 kV My Tho – Duc Hoa TL started in February 2017. During the 2019 Q4 period, no new tower foundations were excavated and no new towers were erected, just 3 km of wire were strung. Until the end of December 2019, the subproject working progress had reached 57% of the total plan. The subproject 500 kV Duc Hoa substation and its connections commenced its civil works in March 2019. There was a significant progress of the substation construction in 2019 Q4. The substation working progress had achieved 74% of the total plan as of 31 December 2019 with 90% of the substation foundation, 100% of the operation house and shift house, oil containers and water containers and 80% of the wall had been completed. The cable channels, substation wall, substation guard house, fire extinguishing and installation of transformers…) had been constructed with about 30% of the works done. For the connection lines, the working progress had little improved. Particularly, 4/69 tower foundations of 500 kV connection line had been excavated and concreted, 33/67 tower foundations of the 1st 220 kV connection line had been excavated, 30 of which had been concreted, and 65/81 tower foundations of the 2nd 220 kV connection line had been excavated, 64 of which had been concreted and 21 towers had been erected. The working progress of connection lines had reached 30% of the total plan.

3. Of the two subprojects managed by CPMB, subproject 220 kV Binh Long – Tay Ninh TL has been operational since 22 June 2019, the remaining subproject 500 kV Chon Thanh and its connections was under construction. Commenced late in 2019 Q3 (05 August), the subproject had made a remarkable working progress until the end of 2019 Q4. The substation construction progress had achieved about 70% compared with the total plan. Concretely, the items of substation foundation, oil containers, water cooling tanks had been totally completed, while about 70% of works of the operation house, 50% of the shifting house, 60% of the cable channel and 50% of the substation wall (50%) had been done. However, for the connection lines, the working progress had little improved. Particularly, 2/2 tower foundations of 500 kV connection lines (CLs) and 4/29 towers foundations of 220 kV CLs had been complete and returned the grounds.

Compliant monitoring activities taken in this period (Q4.2019): Revised 2019 Q3 EMR; Worked with the Environmental officer (EO) of PMBs to collect and review the monthly environmental compliance reports of contractors; Conducted field visits to the sites of subproject 500 kV My Tho – Duc Hoa TL and subproject 500 kV substation and its connections from 10 - 22 December 2019 and to the subproject 500 kV Chon Thanh subproject and its connection from 23 to 31 December 2019, while liaising with PTC4 (the operational agency) to collect the relevant information related to the operation of five second banks of substations and the 220 kV BL- TN TL subproject. Environmental effect monitoring in this period: PMBs have complied with conducting the EEM of the subprojects under construction in accordance with the EMoP since 2019 Q3. The results of EEM of three subprojects 500 kV My Tho - Duc Hoa TL, 500 kV Duc Hoa substation and its connections and 220 kV Binh Long - Tay Ninh TL showed that all analyzed parameters


Page 2

required by the EMoP met the national technical regulations (QCVN). therefore, they were not required to monitor further in 2019 Q4. During the 2019 Q4, the EEM was conducted in subproject 500 kV Chon Thanh substation and its connections because it has just constructed since late of 2019 Q3. The result revealed that the concentration of dust (TSP) at the substation exceeded the standard significantly because of the subproject construction. The surface water quality in the subproject area remained or little increased compared with the baseline data. The wastewater quality at the discharging point of septic tank met the standard before discharging into the environment. Although the number of measured parameters at this time was more than that required by the EMoP, the parameter of oil and grease of the surface water was not measured. The shortcomings will be overcome in the next quarter and the results will be incorporated into 2020 Q1 EMR.

Shortcomings found in 2019 Q3 and the status of overcoming

For subproject 500 kV Duc Hoa substation and its connections:

Shortcomings: The shortcomings found in 2019 Q3 included (I) improper management of domestic and construction waste at sites; (ii) workers working with inadequate PPE; (iii) unsafe installation of the standby power generator without fences and warning sign to prevent unauthorized people from accessing to the dangerous place; (iv) no provision of dustbin specialized for keeping temporarily hazardous wastes in case of it releases at sites and sign a contract with an agency licensed by MONRE to transport and treat the waste following the regulation.

Corrective actions: SPMB’s EO worked directly with the EHS staff of contractor VNECO and CSC at sites on 30 September 2019 to strongly request the contractor to overcome all shortcomings, while SPMB issuing an official document on 24 October 2019 to request the contractor headquarter of VNECO to comply with carrying out the corrective action plan and report the implementation status to SPMB before 30 October 2019. Actually, contractor corrected all shortcoming from 3 to 7 October 2019 (Table 14).

For subproject 500 kV Chon Thanh substation and its connections

Shortcomings: The shortcomings that were identified in 2019 Q3 consisted of (i) gathering materials and equipment on the access road causing difficulties for transportation and risk of traffic accident; (ii) improper management of the construction wastes at site; (iii) workers working at site without adequacy of PPE; (iv) unsafe installation of the spare power generator without fences and dangerous warning sign to prevent any unauthorized people from accessing to the place and (v) no availability of a special dustbin to store temporarily any hazardous wastes (contaminated soil with oil, cloths with oil) in case it released and no contract signed with an agency licensed by MONRE to transport and treat the waste.

Corrections: CPMB’s technical staff worked directly with the contractor manager and EHS staff of contractor at site on the shortcomings, requesting the contractor to prepare a corrective action plan to overcome the shortcomings, while CPMB issued a Document on 24 September 2019 to request the Contractor headquarter of PCC1 to direct the contractor at sites to comply with the implementation of corrective action plan, surmounting all shortcomings within October 2019. Actually, the contractor corrected the shortcomings from 27 to 30 September 2019 (Table 14).

Shortcomings found during 2019 Q4

For ubprojects 500 kV Duc Hoa substation and its connections

- Workers were not wearing the PPE such as sunglasses and gloves when welding and cutting iron, which was potential to cause serious injuries especially with eyes and hands.

Recommendations:


Page 3

- NES together with SPMB technical staff met with the manager and health staff of VNECO and CSC (PEEC2) at site on 16 December 2019 to explain a high risk of occupational accidents for the welders during welding without wearing sunglasses and gloves (PPE) and requested the contractor to order the welders to stop working immediately to wear the PPE before restarting the work. At the same time, the contractor was recommended to ensure all workers must wear adequacy of PPE before working to avoid occupational accidents.

For 500 kV Chon Thanh substation and its connections

- Welders were not wearing sunglasses when welding and cutting iron, which was potential to cause serious injuries especially with eyes.

- Dust was generated much at the substation site because many activities of excavations and transportation within the site under the condition of hot weather, which is potential to pollute the air quality and affect the workers’ health.

Recommendations

- Contractor PCC1 was requested to stop welding immediately to explain to the welders that a high risk of accidents especially with eyes if the welders doing without using adequacy of PPE (sunglasses) and force them to use the PPE when welding and cutting iron on 27 December 2019. At the same time, the contractor was proposed to water the site at least three times/day to ensure it could suppress the dust potential to be generated due to the excavation and transportation activities. The contractor agreed with the proposal and mobilize more sprinklers to water the site in the afternoon of 27 December 2019.

4 SUBPROJECT CONSTRUCTION/OPERATION STATUS

4.1 Summary of work done in the previous and current monitoring periods

15. As of 31 December 2019, all nine subprojects financed under the Tranche III of MFF had been under operation and construction. SPMB manages seven subprojects including the five extension of substation subprojects 220 kV Tra Vinh, 220 kV Vung Tau and Duc Hoa, 220 kV Uyen Hung and 500 kV Cau Bong were under operation and two subprojects 500 kV My Tho - Duc Hoa TL and 500 kV Duc Hoa substation and its connections were under construction. Meanwhile, CPMB manages two (i) subproject 220 kV BL- TN TL was under operation and the subproject 500 kV Chon Thanh substation and its connections was under construction.

16. The subproject 500 kV My Tho – Duc Hoa TL was constructed in 2017 Q1, was suspended for about 09 months from April to December 2018 due to the subproject’s compensation and site clearance issues, was resumed its works in 2019 Q1. However, the construction progress had little improved since then because of the incomplete compensation to the subproject affected land. During the 2019 Q4 period, there were no newly excavated tower foundations and erected towers, just only 3 km of wire was dragged. Therefore the construction progress had remained with 85 out of 112 tower foundations that had been completely constructed, of which 45 towers had been erected and 10.2 km out of 55.1 Km of constructor had been strung.

17. The construction of subproject 500 kV Duc Hoa substation and its connections was commenced in March 2019 and had achieved about 74% and 30 % of the total plans of substation construction and connection lines respectively. For the substation construction, at the end of 2019 Q4, 90% of substation foundation, 100% of operation house and shift house, oil containers and water containers and 80% of the substation wall had been implemented. The cable channels, substation guard house, fire extinguishing and installation of transformers…) had been constructed with about 30% of the works done. For the connection lines, the working progress had little improved because of incomplete compensation to the affected land. The particular working progress of the connection lines were that 4/69 tower foundations of 500 kV connection line had been excavated and concreted, 33/67 tower foundations of the 1st 220 kV connection line had been excavated, 30 of which had been concreted and returned the ground and 65/81 tower foundations of the 2nd 220 kV connection line had been excavated, 64 of which had been concreted, returned the grounds and 21 towers had been erected.

Chon Thanh 500 kV substation and its connections subproject commenced its civil works on 5 August 2019 and had achieved about 70% of the total plan until 31 December 2019. Particularly, 100% of the

foundation of substation, oil tanks and water tanks, 70% of the operation house, 50% of the shifting house, 50% of cable channel and 50% of the substation wall had been complete. The internal roads were not constructed yet. For the connection lines, the work progress had little improved because of incomplete compensation to the affected land. Concretely, 2/2 tower foundations of the 500 kV connection line had been done, and 4 out of 29 tower foundations of the 220 kV connection line had been excavated, concreted and returned the ground.

18. Works done in the previous quarter (2019 Q3) and this monitoring period (2019 Q4) are summarized in Table 5.

5.4.2.2 Complaints

38. There had been no complaints raised by local people regarding environmental performance and environmental impacts until the end of 2019 Q4.

5.4.3 Environmental effect monitoring (EEM)

39. The EEM plan included in the IEEs approved by ADB requires monitoring of (i) Ground water quality; (ii) Surface water quality (quarterly); (iii) Wastewater quality; (iv) Air quality; (v) Noise and (vi) Vibration. However, the Vietnam Environmental Protection Department promulgated Document No.2610/TCMT-TĐ dated 20 December 2015 and the EVN promulgated Document No.5088/EVN-KHCN&MT+VP that allowing not to monitor the surrounding environments for power projects. In case of any issues or complaints which may affect air quality, noise, vibration, underground water or wastewater, relevant environmental effect monitoring will be conducted as necessary (cf. Item 5.3.1.2 of 2017 Q2 EMR7).

40. At the mission taken from 3-7 June, 2019, ADB found that EEM (measurement of air quality, noise level, surface/ground/wastewater quality, etc.) was not conducted following the Environmental Monitoring Plan (EMoP)8. The Mission requested PMBs to conduct the EEM according to the EMoP, and PMBs proposed to carry out the EEM for one time as specified in the EMoP of each subproject9. The Mission agreed with PMBs proposal, although PMBs will be required to continue the EEM if the one-time monitoring result does not meet Vietnamese applicable standards (QCVN). PMBs agreed to conduct the one-time monitoring in 2019 Q3 and report the result through 2019 Q3 EMR.

41. PMBs conducted the EEM following the EMoP of the subprojects that are under construction in September 2019. The monitoring results showed that all analyzed parameters of subproject 500 kV My Tho - Duc Hoa TL, subproject Duc Hoa 500 kV substation and its connections and subproject 220 kV BL-TN TL required to be monitored meet Vietnamese applicable standards (QCVN). The results of EEM of such subprojects were reported in 2019 Q3 EMR that was disclosed on ADB website in December 201910. Therefore, the EEM for such subprojects was not required to be conducted in 2019 Q4 and later unless there are the complaints related to the quality of the subproject surrounding environments that are raised by local people and concerning agencies.

5.4.2.3 Complaints

56. There had been no complaints raised by locals and workers regarding the environmental pollution until the end of 2019 Q4.

KK1 at central of the substation; KK2: (Intersection between the access road to Phuoc Hoa lake and TL of 500 kV Pleiku- My Phuoc – Cau Bong KK3: Intersection between the connection line 220 kV of substation and National highway No. 14.

Remarks:

The result of EEM revealed that the concentration of total suspended particles (TSP) at the K1 location had a significant exceed over the standard because contractor watered not enough to suppress dust generated from many activities of excavations and transportation occurred at the same time within the substation in the condition of hot weather. The concentration of TSP at location of K3 exceeded little the standard, which may be because of local transportation passing the national highway 14. Meanwhile, noise and vibration levels were within the national technical regulations QCVN 26: 2010/BTNMT on noise level and QCVN 27: 2010/BTNMT on vibration level.

The parameter EMF under the 500 kV TL passing over the substation between tower # 6901 -#6902 was monitored by PTC4 yearly. In 2019, it was measured in June and the measured value of EMF was 1.2 kV/m that is far lower the regulation (5 kV/m). Therefore the workers can work safely under the TL with the working time of maximum 8 hours/day.

Remarks:

The number of measured parameters was more than that required by the EMoP, however the parameter of oil and grease was not monitored at this time because of their shortcoming. In the next quarter, the EEMC will be carefully guided to monitor additionally the parameter of oil, grease of the surface water sources as required by the EMoP.

In terms of the water quality, the baseline data measured in August 2014 revealed that the concentrations of BOD5, TSS and PO4-3 of the water sources had exceeded the national technical regulation on surface water quality (QCVN 08: 2015/BTNMT) column A2. The results of EEM conducted in October 2019 when the subproject has constructed for about three months showed that the concentrations of BOD5, TSS and PO4-3 remained or increased little compared with the baseline data, while the indicator pH and the concentrations of NO3- and Coliform were within the standards. This has proved that the surface water sources were not affected by the subproject construction.

59. The environmental monitoring during the operation phase of these substations were conducted by PTC4 which took over the subprojects after the completion of the construction. The


Page 81

environmental performance monitoring has been conducted every day by PTC4’s staff to keep the substations in safe situation. The quarterly environmental monitoring reports were prepared, submitted to the Departments of Natural Resource and Environment of district/city where the substations are located and available at the substations and PTC4’s offices for being reviewed by competent agencies once required. During the operation of these substations, no occupational accidents, no hazardous incidents, no occupational injury for workers has occurred. The status of complying with Environmental compliance monitoring was summarized in Table 27.

b. Environmental Effect Monitoring

60. The environmental effect monitoring plan in the IEEs of second transformers for substations approved by ADB requires to monitor the environmental components of (i) Ambient noise, dust, along access road and inside substation ambient air quality, (ii) underground water quality and (iii) wastewater quality and (iv) Electromagnetic fields (EMF). However, considering the base line data (meeting national standards) and environmental impact caused by the project (not significant), PTC4 decided to measure only Electromagnetic fields annually. In case of any issues or complaints which may affect air quality, noise, vibration, underground water or wastewater during the operational phase, relevant environmental effect monitoring will be conducted as necessary (Cf. Item 5.3.3.2 of 2018 Q2 EMR)13.

61. The EMFs of the five substations were monitored in June 2019 after one month the second transformer for Cau Bong 500 kV substation had been put into operation. In the working places of the substations such as technical, financial rooms and leading rooms, guard houses, the EMFs were not measured because the baseline data in the previous years had showed that the measured figures were far lower than the allowable threshold regulated under QCVN 25/2015/TT- BYT. However, the EMFs in the working places of 500 kV Cau Bong substation was measured in the first year of operation. The results revealed that the EMFs in the working places of Cau Bong 500 kV substation ranged from 0.004 to 0.006 kv/m that are also far lower than the standard (5 kv/m).

62. The EMFs in the power distribution yards of substations were measured in all substations including the 500 kV Cau Bong substation. The results showed that the EMFs range from 2.22 kv/m to 14.71 kv/m. The EMFs were recorded at a low level ranging from 2.22 kV/m to 6.81 kV/m in the substations of 220 kV Vung Tau, Uyen Hung and Duc Hoa, and at a high level in the substations 220 kV Tra Vinh and the 500 kV Cau Bong. It is confirmed that PTC4 updated the layout of substation EMFs based on the results of monitoring EMFs in June 2019, regulating the safe duration of working corresponding to the specific level of EMF in compliance with QCVN 25/2015/TT- BYT. The layout of EMF of 500 kV Cau Bong substation updated when the second transformer put into operation in May, 2019 is an example (Figure 2). The results of EMFs in the yards of power distributions of the five extension substations are summarized in Table 28.

the implementation status to SPMB before 30 October 2019. Actually, contractor corrected all shortcoming from 3 to 7 October 2019 (Table 14).

7.1.2 Subproject 500 kV Chon Thanh substation and its connections

Shortcomings: The shortcomings that were identified in 2019 Q3 consist of (i) gathering materials and equipment on the access road causing difficulties for transportation and risk of accident; (ii) improper management of the construction wastes at site; (iii) workers working at site without adequacy of PPE; (iv) unsafe installation of the spare power generator without fences and dangerous warning sign to prevent any unauthorized people from accessing to the place and (v) no availability of a special dustbin to store temporarily any hazardous wastes (contaminated soil with oil, cloths with oil) and no a signed contract with an agency licensed by MONRE to transport and treat the waste.

Corrections: CPMB’s technical staff worked directly with the contractor manager and EHS staff of contractor at site on the shortcomings, requesting the contractor to prepare a corrective action plan to overcome the shortcomings, while CPMB issued a Document on 24 September 2019 to request the Contractor headquarter of PCC1 to direct the contractor at sites to comply with the implementation of corrective action plan, surmounting all shortcomings within October 2019. Actually, the contractor corrected the shortcomings from 27 to 30 September 2019 (Table 14).

7.2 Shortcomings found in 2019 Q4 and recommendations

7.2.1 For subprojects 500 kV Duc Hoa substation and its connections

- Workers were not wearing the PPE such as sunglasses and gloves when welding and cutting iron, which was potential to cause serious injuries especially with eyes and hands.

Recommendations:

- NES together with SPMB technical staff met with the manager and health staff of VNECO and CSC (PEEC2) at site on 16 December 2019 to explain a high risk of occupational accidents for the welders during welding without wearing sunglasses and gloves (PPE) and requested the contractor to order the welders to stop working immediately to wear the PPE before restarting the work. At the same time, the contractor was recommended to ensure all workers must wear adequacy of PPE before working to avoid occupational accidents.

7.2.2 For 500 kV Chon Thanh substation and its connections

- Welders were not wearing sunglasses when welding and cutting iron, which was potential to cause serious injuries especially with eyes.

- Dust was generated much at the substation site because many activities of excavations and transportation within the site under the condition of hot weather, which is potential to pollute the air quality and affect the workers’ health.

Recommendations

- Contractor PCC1 was requested to suspend the work immediately to explain to the welders that a high risk of accidents especially with eyes if the welders doing without using adequacy of PPE (sunglasses) and force them to use the PPE when welding and cutting iron on 27 December 2019. At the same time, the contractor was proposed to water the site at least three times/day to ensure it can suppress the dust potential to be generated due to the excavation and transportation activities. The contractor agreed with the proposal and mobilize more sprinklers to water the site in the afternoon of 27 December 2019.
