38 7 SUMMARY OF ENVIRONMENTAL EFFECT MONITORING 7.1 Monitoring location and frequency 33. Environmental effect monitoring should be conducted in line with the national regulation and as required in IEE. The required monitoring aspects are: noise and air quality (for all 5 subprojects), surface water quality (for 4 subprojects, except rehabilitation of Son Tay 110KV substation) and soil quality (only for two subprojects Rehabilitation of Son Tay 110KV substation and Thuong Tin - Thanh Oai transmission line). The requirement of environmental effect monitoring stated in IEEs of 5 ongoing subprojects are summarised in Table Three subprojects namely (Rehabilitation of Son Tay 110KV substation, Phu Nghia substation and connecting line, and Thuong Dinh Substation) have conducted monitoring during construction phase until operation phase at 2017 Q1 and Q However, for Thuong Tin- Thanh Oai, environmental effect monitoring was not conducted during the construction stage (from September 16 and ended in April 2017), but only for one time in 2017 Q2 during the operation stage, because tower foundations are installed mainly at agricultural land where now residential area is located and no water sources exist nearby. In addition, the construction time of each tower is short (about one month), thus the environmental impact on each tower location is negligible. After first environmental effect monitoring as required by Vietnamese regulation (frequency of one time during construction phase) contractors stopped conducting monitoring since budget located for environmental effect monitoring is based on Government requirement only. 36. The environmental effect monitoring is not required for Son Tay TL subproject, so this one was conducted one time only during pre-construction phase. 37., and the status of environmental monitoring analysis of each subproject is summarized in Table

50 10 CONCLUSION AND RECOMMENDATION 10.1 Conclusions 55. The compliance with requirements during construction phase is generally good. Almost all impact mitigation measures have been implemented. 56. The main environmental issues of the five subprojects are related to: - Hygienic condition of worker camp: Kitchen and toilet are not clean - Management of construction and domestic solid waste: domestic solid waste and construction solid waste were not properly collected and disposed - Workers use of working protective facilities - Protective measures for community safety. 57. These environmental issues occurred over the last 6 months (July-December 2016). When the site visit was conducted on 17 November 2016 during the previous monitoring period, some environmental problems were identified, and it was found that EMP of subproject was not always followed. EVN HANOI issued an official letter to the contractors and CSCs on 26 November 2016 (Appendix D of this report), to remind contractors of the EMP requirements and request them to settle all backlog issues on each site, and give them one week to address all. After one week, the CSC at each site reported to Environment Officers of EVN HANOI all the last issues were solved. Then Environment Officers of EVN HANOI inspected sites and confirmed that. 58. The environment issues were mitigated after inspection by Hanoi DPMB environmental staff and PIC. However, these problems continued to occur in this six months (Jan-June 2017) and are being remediated immediately after reminders of the environmental inspection team. 59. These problems continue to occur indicates the environment officers of EVN Hanoi did not inspect construction site frequently, and they, together with CSCs and EOs of constructors on each site, should enforce workers follow strictly the requirements of environmental protection. 60. All subprojects have no complaints from residents living surrounding the subproject area on the environment issues Recommendation 61. Based on the main environmental issues of the five subprojects stated in conclusion section and detailed in section 8 for each subproject, the corrective actions/solution as well as required closed date for each issue is presented in 50

51 62. Table 27. Environment officers of EVN Hanoi should inspect construction site more often, and CSCs and EOs of constructors on each site should enforce workers to follows EMP. Since the stated environmental issues are common and easily to be corrected/mitigated, hence the closed date is taken immediately or one/two weeks after PIC visit. The inspection was conducted one/two weeks later by Hanoi DPMB environmental officer or PIC to confirm the implementation of mitigation measure being done. All the environmental issues identified in this monitoring period were addressed by May
