EXECUTIVE SUMMARY
In 2005, the Asian Development Bank (ADB) financed a Project Preparatory Technical Assistance (PPTA) to provide consultants that will assist the Northern Power Project Management Board (NPPMB) in the preparation of Initial Environmental Examination (IEE) for the following three core subprojects: (i) 500 kV Son La Hoa Binh and Son La Nho Quan transmission line, (ii) 220 kV Thanh Hoa Nghi Son Vinh transmission line, and (iii) extension of Van Tri 220 kV substation. The IEE for Son La – Hoa Binh – Nho Quan Transmission Line (TL) and 220kV Thanh Hoa –Vinh Transmission Line Subprojects were both approved by ADB and the Government of Viet Nam and will be updated and finalized following the detailed design, subject to ADB review and approval. For the Van Tri Substation, it was determined during the PPTA that no land acquisition will be involved and no IEE was prepared. The PPTA consultants also prepared an Environment Policy Framework to guide the NPPMB in the preparation of IEE for the following subprojects: (i). Son La Hiep Hoa 500 kV Transmission Line (TL);
(ii). Quang Ninh Mong Duong 500 kV TL;
(iii). Hiep Hoa 500 kV substation;
(iv). Expansion of 500kV Thuong Tin; and
(v). Ha Tinh Thach Khe 220 kV TL
At present, two subproject (Ha Tinh Thach Khe 220kV T/L and Quang Ninh Mong Duong 500kV T/L) have been replaced by three new subprojects (500kV Nho Quan substation 2nd transformer, 220kV Tuyen Quang substation and 220kV Bim Son substation). To utilize the loan savings, the Electricity of Viet Nam (EVN) with the agreement of ADB decided to add three more subprojects into the Loan 2225 VIE namely Kim Dong 220kV substation, Hai Duong 2 220 KV substation and Thuong Tin Kim Dong 220kV T/L. As such, in the VIE 2225 framework, there are 12 subprojects namely (i) Son La – Hoa Binh – Nho Quan 500kVTransmission Line, (ii) 220kV Thanh Hoa – Vinh T/L; (iii) Son La Hiep Hoa 500 kV Transmission Line; (iv) Expansion of 500kV Thuong Tin; (v)Extension 220kV Van Tri Substation; (vi)Hiep Hoa 500 kV substation; (vii) 220kV Bim Son substation; (viii) 220kV Tuyen Quang substation; (ix) Extension 500kV Nho Quan substation 2nd transformer; (x) Kim Dong 220kV s/s; (xi) Thuong Tin Kim Dong 220kV T/L; and (xii)Hai Duong 2 220 KV s/s. On February 2, 2010, Northern Power Project Management Board (NPPMB) and VICA International Consultants Company (VICA) signed a consultancy contract on “Resettlement and Environmental Consultancy of Northern Power Transmission Expansion Project funded by ADB”. VICA will help NPPMB to supervise the environmental compliance of subprojects during the construction and operation stages. In 2011, the 4th, 5th, 6th and 7th monitoring reports were prepared and submitted to NPPMB. In 2012, the 8 th , 9th , 10 th and 11 th monitoring reports prepared by VICA were implemented in April, June, September and December, respectively Due to the changes on the list of subprojects and other issues during the project implementation, there was a need to have corrective action plan to comply with the requirements of the ADB environmental safeguards. To assist the NPPMB in its compliance with the environmental safeguards of ADB, a local implementation consultant (LIC) for the environment was employed in the project. The LIC was engaged in the project for 22 months, starting March 2012.

2.1 500 kV Son La- Nho Quan- Hoa BinhT/L and 500kV Son La-Hiep Hoa T/L Subprojects
2.1.1 Background of 500 kV Son La- Nho Quan- Hoa BinhT/L
7. The length of transmission line is 289.9km, in which the double circuit is 177km and two single circuits are 28.6km and 77.3km. The subproject passes through the provinces of Son La, Hoa Binh and Ninh Binh provinces, 11 districts, and 36 communes. The transmission line includes a 25km offshoot line to a switch bay in Hoa Binh. The subproject is comprised of the construction and installation of; (i) 269 km of double circuit 500kV transmission line and associated composite optical fiber earth wire, (ii) 500kV, 65MVar Shunt Reactor, (iii) 500kV capacitor, and (iv) 500kV switch gear. The construction component of subproject completed and the transmission lines were put in use in December 2010. This is one of the three core subprojects aimed to improve the electricity branch structure of the Northern Transmission Power Cooperation (NPT) and the power supply capacity in Viet Nam.
8. The transmission line was fully energized in November 2010 and has been transmitting power from Son La hydropower since December 2010. 2.1.2 Background of 500kV Son La - Hiep Hoa Transmission Line
9. The total length of Son La Hiep Hoa T/L was 268.47km. The right of way (ROW) of the T/L was determined in the Decree No. 106/2005/NĐ CP and for 500 kV transmission line which was delimited by two vertical planes in parallel to the line on two sides and the distance from the planes to the nearest wire was 7m. The average width of the ROW was 30.45m. The starting point of Son La – Hiep Hoa 500kV T/L was the Son La 500KV substation and the ending point was Hiep Hoa 500KV substation. The T/L traversed 19 districts.
10. The transmission line has been in operation since 31 March 2012 and it is temporarily under the management of the operation unit. 2.1.3 Environmental Compliance of 500kV Son La - Hiep Hoa and Son La-Nho Quan-Hoa Binh Transmission Line
11. On May 2011, VICA carried out its 4th monitoring mission to some sites of the subprojects. It was found that there were no environmental issues during the operation of the subproject. It was also reported by the local resident living along the ROW of the subproject that there was no significant impact of electromagnetic field during the operation of the subprojects.

Picture 2. Hoa Binh PTC Picture 3: North West PTC
13. 500kV Son La Hoa Binh Nho Quan T/L and 500kV Son La Hoa Binh subproject are supervised and managed by the Hoa Binh Power Transmission Company (PTC) and North West Power Transmission Company, respectively. The consultant team worked with Hoa Binh PTC and North West operation units to review the existing management of two transmission lines under the project. The key contents focus on type of ROWs, guidelines and frequency of ROW and tower inspection, waste collection after ROW clearance, and other potential problems that may be encountered during the operation of the transmission lines.
14. Operation Management: The number of workers of each unit is approximately 20 persons. Their duties are to operate and maintain not only towers under the project but also other towers allocated by National Transmission Line Company. Each worker performed five field inspections in a month to inspect tower and ROW allocated and the maintenance of the transmission line. The remaining working days are spent at the office unit. All offices are provided with sanitation facilities including drainage, hygienic toilet with septic tank and waste bins for waste collection. Thus, the environmental impact of the operation of the office is insignificant.
15. Right of way (ROW) maintenance: The type of ROWs under two these transmission lines are the following: (i) Plantation forest (i.e. in Tam Duong, Moc Chau districts) or (ii) Natural forest (i.e. in Mai Chau, Moc Chau districts); or (iii) Rice or crop fields (corn and cassava) (i.e. on the plain in Nho Quan district, on the hill in Mai Son district). ROW maintenance plays an important role in power transmission operation. The frequency of transmission line inspection is specified by the National Transmission Line Company as:
• ROW inspection (including ROW clearance, if any): (i) during the day/ day time: every month; (ii) at night time: every three months;
• Technical inspection: (i) At unit: every month; (ii) at power transmission branch: every three months;
• Intensive inspection: prior to holidays such as New Year, Independent day, Labour day, political or socio economic events such as Party congress, National Assembly meeting, People’s Council meeting, extreme weather conditions such as storm, heavy rain, or overloaded transmission line; and
• Incident inspection: Accidents (i.e. lightning, for example).
16. Based on the IEE, the use of chemicals like herbicides and pesticides in ROW clearance has the potential to have a significant impact on the environment. In the project, all transmission line units confirm that no pesticides and herbicides were used during ROW maintenance.
Semi-Annual Environmental Monitoring Report Page 13 VIE 2225 NORTHERN POWER TRANSMISSION EXPANSION SECTOR PROJECT
ROW clearance is done by mechanical equipment like machete and electric hand saw as shown below.

17. Waste collection after clearance: For grasses and small trees, the leaves cut from the clearing operation were left inside the tower for natural decomposition. However, no more weeds can develop inside the tower; there is no impact on the tower. For larger trees, the timber is given to the owners.
18. Difficulties in ROW management: Some sections of ROWs in the Son La Hiep Hoa 500kV transmission line were not accounted and officially handed to the operation units. In order to facilitate the transfer of management to the operation unit, NPPMB should conduct the inventory of trees and properties inside the ROW. Other ROWs for the transmission line are properly maintained.

19. Labor safety : To ensure work safety in an electric company, safety procedures and guidelines are prepared and applied by all operation units including: (i) Decision No. 1186/QD EVN dated 07/12/2011 issued by EVN on Standard No. QT 03 01; (ii) Decision No. 0299/QD NPT dated 12/11/2012 issued by NPT on Standard No. QT 04 12.
20. Safety training is conducted annually and personnel protective equipments (PPE) are provided to all the workers. Personnel protective equipment consist of clothing, helmet, boots, for each
Semi-Annual Environmental Monitoring Report Page 15 VIE 2225 NORTHERN POWER TRANSMISSION EXPANSION SECTOR PROJECT
worker and one electromagnetic field protective clothing for each unit when working on tower operation. For the large repair of transmission line, the PPEs is included in the general work cost.

21. As regulated, health of all workers are examined all workers’ health are examined every six months at the given hospitals or clinics. However, prior to working on the electricity tower, health examination must be conducted at medical room under transmission line unit.
22. Hazard and Risk Management : Landslides surrounding the tower, lightning are some incidents arisen at Son La – Hiep Hoa 500kV transmission line. The occurrence of storms or heavy rains is the main reason for these incidents. To protect the base of the tower, revetment and
Semi-Annual Environmental Monitoring Report Page 16 VIE 2225 NORTHERN POWER TRANSMISSION EXPANSION SECTOR PROJECT
drainage are constructed surrounding the tower (Photo 14 15). However, the revetment would sometimes slide the tower No. 90, for example. (Photo 16 37)

23. Transmission lines are a potential hazard to aircraft during takeoff and landing. To ensure safety, each tower with over 70 m high will be painted red and white colors to improve the visibility to pilots and lessen the risk of collision.
24. Electromagnetic field: As regulated in IEE, EMF should be annually measured, yearly at the least. However, only EMP of Son La – Hiep Hoa 500kV transmission line has been measured many times by power transmission branches up to the monitoring time. For Son La – Hoa Binh – Nho Quan 500kV transmission line, only Tay Bac Transmission Unit has carried out electromagnetic field measurement at two locations out of the ROWs, closed to residential area at tower No.95 and 96 – Na Bo commune, Mai Son district, Son La province.
25. According to the regulation at Article 1 (4.2.a) of Decree No. 81/2009/ND CP dated 12/10/2009 by the Government on some amended articles of Decree No. 106/2005/ND CP dated 17/8/2005 by the Government stipulating the detail regulation and guideline of some articles of Electricity Law on safety protection for high voltage grid. The results compared with the current regulation showed that all meet the standard and as the previous measured results ( please see annex 3)

2.2.1 Background of 500 kV Hiep Hoa Substation
26. CPPMB is implementing Hiep Hoa 500 kV substation project. The substation is to be powered by Son La hydropower station through 300 km long 500 kV transmission line. Prime Minister’s approval for construction and investment plan of 500 kV Son La Soc Son transmission line in was obtained in 2005. The original location of substation was proposed at Soc Son. In April 2006, it was decided to move the location of the 500 kV substation from Soc Son to Hiep Hoa situated about 10 km north because the original location is a flood prone area and the provincial authorities not agreeing to the. Two of the three 500 kV power transformers of Hiep Hoa substation were commissioned on 17 December 2011 and the third unit was commissioned on 27 March 2012.
Picture 20. Hiep Hoa Substation Main Picture 21. 500kV Hip Hoa Substation Office
Semi-Annual Environmental Monitoring Report Page 18 VIE 2225 NORTHERN POWER TRANSMISSION EXPANSION SECTOR PROJECT
27. Hiep Hoa 500kV substation was built to meet the increasing demand of electricity in the the Northern power system, especially Hanoi area, while receiving power from the hydro power plants in the Northwest area and thermal power plants in the Northeast area, especially Son La hydro power plant and Quang Ninh and Mong Duong thermal power plants. Besides, Hiep Hoa Substation creates circuit connections between the regions in the electrical system, enhancing the safe operation and the stability for the national electricity system, reducing power loss in the transmission network. Therefore, the construction of Hiep Hoa 500kV substation is needed for the improvement of the national electricity system. 2.2.2 Environmental Compliance
28. On March and September 2012, LIC visited the site and on June and December 2012, VICA has carried out the 11th monitoring mission to the project site. It was reported that there were no significant environmental issues in the area from the operation of the project. The following were observed during the site visits:
29. Hazardous wastes management: Electrical transformers and other substation equipment used oil for insulation and cooling. There are three transformers using a total of 50 tons of oil. The oil used in the equipment does not contain PCB. However, disposal of equipment containing oil must follow the guidelines on the proper disposal of hazardous wastes. In order to prevent a potential oil leak to surface water, the site will be graded to direct surface runoff to two underground oil ponds (about 100 m 3 for each). A berm was built around all oil filled equipment and a buried drain pipe will direct surface runoff, along with any oil, to the oil pond. Any accidental release of oil will be contained until it can be collected, transported, treated and disposed by an accredited hazardous waste transporter, treater and disposal plant. These mitigating measures will minimize the potential impacts on the environment of the accidental release of oil.

2.3 220kV Thanh Hoa – Vinh Transmission line
2.3.1 Background of 220 kV Thanh Hoa-Vinh T/L
37. Thanh Hoa Vinh 220 kV Transmission Line was one of three core subprojects of Northern Power Transmission Expansion Project (other two projects are 500 kv Son La Nho Quan Hoa Binh T/L and Van Tri S/s). The line has a length of 148.3 km passing through ten districts of the two provinces of Thanh Hoa and Nghe An.
38. The 220kV Thanh Hoa – Vinh transmission line will be connected to three substations. For the project activities, the feeder bay of all three substations would be constructed to expand the substation including (i) 220KV Thanh Hoa Substation, (ii) 220kV Nghi Son Substation, and (iii) 220KV Hung Dong Substation. At this quarter, only 220kV Hung Dong Substation has started construction.
2.3.2 Environmental Compliance
39. In order to take over the supervision duties from VICA starting in 2013, LIC started the spot check monitoring to some sites of subproject in Vinh city, Nghi Loc and Dien Chau district, Nghe An province in September 2012. In particular, LIC has visited the Hung Dong 220Kv S/S, which is the ending point of the 220KV Thanh Hoa Vinh S/S. In Nghi Loc districts, LIC visited some towers and consulted with some DPCs of Nghi Van and Nghi Hung. Similarly, LIC has visited some towers and consulted with some DPCs of Dien Cat and Dien Tho in Dien
Semi-Annual Environmental Monitoring Report Page 23 VIE 2225 NORTHERN POWER TRANSMISSION EXPANSION SECTOR PROJECT
Chau district, Nghe An province. Most of the visited towers are located in sensitive areas of road crossing, cemetery, river, worker camp, material storage locations.
40. The observations from the site visits and consultations are the following; (i) There are no significant environmental pollution due to the construction activities; (ii) the construction of tower foundation has temporarily affect the agriculture practice and in order to address the temporary impact, the contractors/NPPMP compensated the affected people; (iii) the construction of tower foundation has temporally stopped in prevention forest in Nghi Loc district and angle tower position due to land conversion agreement with the Nghi Loc forest management and the lacking of spare part of the angle tower which should be supplied by NPPMB; (iv) the consulted CPCs agreed and supported the subproject and suggested that the best month for the tower construction is in November or December, after the harvest season of farmers; and (v) some household under the ROW of the T/L are concerned on the health effects of electromagnetic field during the operation of the subproject;
41. On November 2012, VICA carried out the 11th monitoring mission to some sites of the subproject. Up to the monitoring time, 93% of tower foundation and 22% of tower erection completed (Annex1), the project progress is behind the agreed schedule for the following reasons: (i) The handover sites to contractors is pending: 26 towers (accounting for 7%), in which: 10 towers from No. 160A to No. 169A in the protection forest (Nghe An province) are in need of the Government’s permission and 16 towers located in the resident land: no agreement with the compensation price is the reason that the sites is not handed over to contractors; (ii) Accessories for tower erection and stringing are not fully supplied by NPPMB.
42. The contractors complied with the mitigation measures to minimize the impact on the environment and on the people in the project area. In particular, there are some issues as following: (i) Rehabilitation of the project area upon completion of site work has been mostly conducted by contractors; (ii) Some sections of the existing roads were used as access road. The contractors have consolidated or repaired after construction completion. In particular the contractors have back filled the top soil, to repair the access roads; (iii) Construction materials gathered at the road side could obstruct the traffic safety but only in some road sections; (iii) The domestic and construction waste were found in some construction sites; (iv) Even the contractors have been complied with labor safety regulations by wearing labour protective equipment, especially helmet, safety belt for workers; but there some workers are not using boots and gloves at the construction site.

44. Labor Safety : Only a limited towers are under erection during the monitoring time because each contractor have one or two teams (each team consisting of 12 workers) for tower erection, and each team can be erected for one tower. As mentioned in the previous Semi Annual Environmental Monitoring report, work safety is especially taken notice during tower erection. Objects and workers falling from height are reminded by contractors. Even the contractor has been complied with work safety regulations by equipped labour protective equipment, especially helmet, safety belt for workers; some workers are not using boots and
Semi-Annual Environmental Monitoring Report Page 26 VIE 2225 NORTHERN POWER TRANSMISSION EXPANSION SECTOR PROJECT
gloves at the construction site (Picture 44 45). The consultant team still reminds all workers and all contractors taking more notice on that for the next towers and coming activities .
