SOME OF MAN TECHNCAL SPECFCATONS FOR THE PROJECT Medium votage MV substation * To reduce the investment cost, faciitate site instaation and uniform project standards, the foowing is to be impemented: * A new substation are designed as outdoor type poe mounted. With substation capacity S>75 kva two poe type construction wi be used. With substation capacity S < 31.5 kva one poe type construction is used. * Re-use the existing transformers if possibe and not consider rehabiitation. Substation rehabiitation is carried out yeary according to the EVN maintenance pan. * Substation requiring reocation or new poe support structures are to be buit as outdoor type, mounted on poes. D The new substation are a poe mounted, as foows: * f capacity S>= 75 kva, mounted on two poes; 3 * f capacity S>= 31.5 kva, mounted on 1 poe. Substation poes are centrifuga concrete type of 10 m or 12 m ength, Cass C suitabe for any requirement. Substation base (foor) is fied 0.3 m deep with soi and covered by mixture of cement and broken bricks MV ines Votage eves: MV ines are designed to accommodate any future votage eve, defined in the power network deveopment and panning scheme for Lao Cai Province. n the ong-term, votage eves 35 kv, 22 kv and 10 kv of MV power networks are used, in conformance with votage of existing 110 kv and 35/10 kv substations and transformer station to be buit in Branches suppying power to transformer station at 35 kv wi be connected into the existing 35 kv ines and designed at the 35 kv votage eve.. Poe size A poes are 10m, 12m, 14m, 16m and 20m ength of casses A,B,C,D. Poe size seection is based on the safe cearance to ground, transportation and traffic structures, crossings, deveopment requirements, sharing of ines for MV and LV votages. Poe strength is seected from oad requirements. n genera, the use of poes is as foows: * For singe circuit ines: centrifuga concrete poe 10m, 12m. *For doube circuit ines: centrifuga concrete poe 14m. Stayed, crossing positions and specia positions: 16m, 20m poes. Poes are manufactured to Vietnam Standards and Reguations DNT-QDKT-09/2000. Poe foundation To support poes, cast in situ M150 concrete foundations are used. 8

11 n the Project, MT1, MT2.. MT8 type foundations are used. The seection of foundations for each position is specified in the design stage, based on estimations of oca soi, geoogica and hydrogeoogica conditions. For sand areas, types of cast in-situ excavated foundations: MO1, M02, M03, M04 are used. For marshy and areas, foundations shoud be reinforced by bamboo stakes, bamboo rafts to strengthen the bearing capacity of foundations and to reduce stress against the foundation surround. Foundation depth is 10-12% of poe height pus 0.3m Low votage Eectricity poe Concrete poes for most ines are H-section type, cast in workshops. For 3 phase ines and branches aong inter-district, inter-commune roads: 7.5m, 8.5m poe sizes. For two wire branches to communes: 6.5m, 7.5m poe sizes. For 1 phase ines into househod groups: 6.5m poe size. A A-B-C type poes according to bearing requirements of each position; manufactured to the standard DNT-QD KT-09/2000. For poes near vehice transport areas: use 10 m, 12 m centrifuga concrete poes to ensure safe cearances. For MV, LV ine co-sharing positions: use MV ine concrete poes. Most concrete poes are A and B-type poes, manufactured to standard DNT-QDKT-09/2000. Square concrete poes and circuar concrete poes are used at the foowing positions: * Straight, corner positions of 3 phase trunk ines: singe poes; and * Corner anchor, straight anchor, end anchor: doube poes. f poes are instaed near househods, trafficabe roads, doube poes shoud be used at corner anchoring, straight anchoring, end anchoring positions; stayed tension poes are used ony at such high bearing positions that doube poes coud not sove and tension poes are convenienty paced; Utiize existing poes which are of good quaity and satisfy the standard when instaing new conductors. Poes under 7.5m size are not used for 3 phase trunk ines. Poes recovered from ines are to be returned to ocaities to aow peope to re-use poes to support suppy ines to houses. Poe foundation To support ine poes, cast in-situ M 00 concrete bock foundations are used: U * For singe poes: use MV1, MV2 * H doube poes: use MV3. The depth of foundations is in proportion to poe heights and is shown in the overa ayout of LV poe, cross-arm and foundation. f doube poes cannot satisfy the high bearing requirements and are in tension poe positions, it is required to use: 9

12 or D14 tension poes with foundation in proportion to poe height. Tension poes contain 1E14 round hot dipped stee according to Vietnamese Standards; * MN 15-5 anchors buried m according to bearing requirements and site cearance; * MN stayed-on-the-spot anchors in sand areas. For ines across sand areas (rivers, coasta), cast in-situ M100 concrete excavated foundations are used, in combination with pre-cast M200 reinforced concrete round pipes with k000, /E1200, /E1 500 diameter. For reused poe positions, if conductor size increased by two or more sizes, must increase concrete in the existing foundation to ensure bearing requirements are satisfied.

14 4. ASSESSMENT OF ENVRONMENTAL MPACTS 4.1. CLASSFCATON OF MPACTS The Environmenta mpact Assessment focuses on the major environmenta issues of the Project's Most Favoured Aternative. The potentia impacts of the Project's pre-construction, construction, and operation phases were assessed as being in one of five categories: i. NO MPACT. The potentia impact of the Project activity is assessed as NO MPACT if the project activity is physicay removed in space or time from the environmenta component. ii. MAJOR MPACT. An impact is said to be MAJOR if the project activity has potentia to affect an 3 environmenta component. Major impacts coud be "Major Negative" or "Major Positive." The foowing criteria were used to determine whether a given impact is MAJOR: 3 a) Spatia scae of the impact (site, oca, regiona, or nationa/ internationa); b) Time horizon of the impact (short, medium, or ong term); c) Magnitude of the change in the environmenta component brought about by the Project activities (sma, moderate, arge); d) mportance to oca human popuations; e) Compiance with nationa, provincia, or district environmenta protection aws, standards, and reguations 3 f) Compiance with Vietnam's internationa commitments. These incude the Convention on Wetands of nternationa mportance especiay as Waterfow Habitat (RAMSAR), the Convention Concerning the Protection of the Word Cutura and Natura Heritage (Word Heritage Convention), and the Convention on nternationa Trade in Endangered Species of Wid Fauna and Fora (CTES); and 3 g) Compiance with Word Bank guideines, poicies, and reguations. iii. MNOR MPACT. f an impact occurs but does not meet the criteria for a Major mpact it is assigned the category MNOR. Minor impacts coud be "Minor negative" or "Minor Positive." MTGABLE MPACT. The potentia impact of a project activity on an environmenta component is said to be MTGABLE if there is potentia for a major negative impact and the proposed mitigation measure wi prevent the impact or reduce the impact to acceptabe eves. 12

15 4.2. DENTFCATON OF POTENTAL MPACTS OF THE PROJECT The Project wi pay an important roe in the eectrification program and in impementation of the poicy of poverty aeviation of 19 communes within 6 distrcts of Lao Cai province. t wi aso promote the poicy of industriaization and modernization of the Government of Vietnam as we as create a great 3 opportunity for overa socio-economic deveopment of the poor area. When the distribution ines are constructed, there is a trend of oca peope to move to ive near the ines. The oca peope committee wi have a proper panning accordingy to support the deveopment of the areas. These panning are incuded: road, residentia area, industria deveopment and farming etc. The communes/districts wi move toward its panning. 3 Beside the significant beneficia impacts, the project may cause different adverse impacts on the environment and oca socio-economy. By using Environmenta Screening Data Checkist and Environmenta baseine Checkist as guided in Framework for Appying Environment Safeguards to Rura 3 Energy Project, The potentia impacts of the Project are described in Tabe 4.1. g.

There are two Project's communes named Nam Xay, Nam Xe are ocated in Hoang Lien Son- Van Ban proposed nature reserve. The foowing section wi be discussed about biodiversity vaue and potentia impacts that might cause to the nature reserve by impementation of the Project. J NTRODUCTON TO HOANG LEN SON- VAN BAN PROPOSED NATURE RESERVE ManageHoang Lien Son-Van Ban is not isted on any govemment decision regarding the Specia-use Forests system, nor is it incuded on a ist of Specia-use Forests to be estabished by the year 2010, prepared by the * FPD of MARD (FPD 2003). However, Lao Cai Provincia FPD, with support from the WWF Strengthening Protected Areas Management in Vietnam Project, have proposed the estabishment of a nature reserve at the site (SPAM 2002). This proposa has been incorporated into the approved provincia management strategy for Specia-use Forests (Lao Cai PPC 2003). * g According to Lao Cai Provincia FPD (in ift. 2003), Hoang Lien Son-Van Ban proposed nature reserve covers 31,189 ha in Nam Xay, Nam Xe and Minh Luong communes, Van Ban district. n addition, a 31,128 ha buffer zone is proposed in Tham Duong, Duong Quy, Dan Thang and Nam Chay communes. To date, however, a management board has not been estabished, and the site remains under the management of Van Ban District FPD. e,.,.a ; M O M0 S, Hoang Lien Son-Van Ban proposed nature reserve is situated in the Hoang Lien mountains, 40 km southeast of Mount Fansipan, the highest mountain in Vietnam. The proposed nature reserve is mountainous, with many peaks over 2,000 m. The highest point (2,875 m) is in the north of the proposed nature reserve, on the border with Hoang Lien Nationa Park. The district is bisected by a river vaey, which runs from south-west to north-east. Eevations aong this vaey are ess than 200 m. ~ ~~ ::.J -i. Remote sensing data revea that Van Ban district supports the argest area of natura forest in the Hoang Lien mountains of Vietnam. n addition, Van Ban district is one of the few parts of the Hoang Lien mountains to support significant areas of hi evergreen forest, a vegetation type that has been amost entirey ost from Hoang Lien Nationa Park (Tordoff et a. 1999), and is scarce in other parts of the Hoang Lien mountains and esewhere in northern Vietnam. Hi evergreen forest is distributed at eevations between 600 and 1,400 m. Whie this habitat has been degraded by seective timber extraction, the forest canopy is sti cosed in most areas. Eevations between 1,400 and c.2,200 m support ower montane evergreen forest. Upper montane evergreen forest is distributed at eevations between c.2,200 and at east 2,650 m. Lower montane evergreen forest is characterized by the presence of the gobay near-threatened conifer Fokienia hodginsii. n addition, anthropogenic habitats, incuding grassand, scrub and agricutura and, are present at various eevations (Averyanov et a. 2002a). Between 2000 and 2002, a series of fied surveys were conducted by the Fauna & Fora ntemationa (FF) Vietnam Programme, BirdLife nternationa and other organizations, during which a number of gobay threatened mamma species were recorded in and around the proposed nature reserve, most notaby Back- cheeked Crested Gibbon Hyobates concoor and Owston's Civet Chrotogae owstoni (S. Swan verbay 2002). The site was aso found to be important for bird conservation, as it supports a number of species of 23

26 U conservation concern, incuding the gobay vunerabe Beautifu Nuthatch Sitta formosa (Tordoff et a. 2002). Consequenty, the site quaifies as an mportant Bird Area (Tordoff 2002). Furthermore, the site supports Vietnamese Saamander Paramesotriton deoustai, a gobay vunerabe amphibian species, currenty known ony from northem Vietnam (Tordoff et a. 2002). Finay, a number of gobay threatened pant species have been recorded at the site, incuding the gobay vunerabe conifer Taiwania cryptomerioides, which is known from no other site in Vietnam (Farjon 2002, Nguyen Tien Hiep et a. 2002). A tota of 1,275 peope ive inside the proposed nature reserve, and a further 9,533 peope ive in the buffer zone (Lao Cai Provincia FPD in itt. 2003). Many of the inhabitants of Van Ban district practice wet rice cutivation in vaey bottoms; however some househods sti practice shifting cutivation on hi sopes. Loca peope engage in a number of activities with negative impacts on biodiversity, incuding hunting and seective 3 extraction of high vaue timber species, particuary Fokienia hodginsii. One human activity with potentiay significant impacts on biodiversity in Van Ban district is cardamom cutivation. Athough some canopy trees are retained in cardamom pots, canopy cover can be reduced by up to 80%, through indiscriminate remova of trees, and current methods of drying cardamom pods require more firewood than can be generated within the pots. ndirect impacts incude hunting and expoitation of non-timber forest products by farmers staying in the forest for extended periods during the panting and harvesting seasons. Van Ban district is bisected by a river vaey, aong which runs provincia road 279. Forest has aready been ceared aong this road for cutivation and human settement, isoating forest areas in the north of the district from those in the south. Some of the most extensive areas of reativey undisturbed evergreen forest, particuary hi evergreen forest, are ocated in the south-east of Van Ban district, outside of the proposed nature reserve. These areas support important popuations of a number of species of goba conservation concern, incuding Back-cheeked Crested Gibbon, Vietnamese Saamander and T. cryptomerioides, and shoud be paced under appropriate conservation management, through either Specia-use Forest designation or oca stakehoder-based approaches. t is of particuar concern that some of these forest areas are designated as production forest, and have quotas for the extraction of high vaue timber species, incuding F. hodginsii PROJECT ACTVTES CARRED OUT N THE PROPOSED NATURE RESERVE Tabe 4.5.
