The substation has two transformers which are not working due to some malfuncti ning. One is rated 132/33kV; IOMVA was manufactured in 1962 and the other is 132/33kV; SMN A also of 1962. It is proposed to upgrade the substation by installing two new power transform rs in the range of IOMVA together with switchgears. Other tasks will include changing th circuit breakers, current transforrmers, protection and control devices, supporting structures, add ng surge arrestors on all line feeders. Also the civil works will cover the upgrade of the internal nd external fence, substation drainage system and the building. 3.19.1 Audit flndings and the required remedial actions: Chalinze Substat on The audit found the following: 1. The sub station has transformers and oil circuit breakers of 1962. Hence by e limination method (i.e. transfornners and switchgears mnade after 1980 are classified as PCB fre ) the substation is -PCB suspect. However the weight of the oil is 25,800 British pounds (11,72 .3 kg) and volume of the oil is 2,990 British gallons (13,593 litres), which means the densit of the liquid oil (11,727.3 kg/13,593 Its = 0.86 kg/Its 3 ) is less than the density of water (no e: density of PCB oil is heavier than water i.e. Ikg/Its 3 ) 2. There was an oil leakage in one tmnsfonner 3. It has three (3) window air conditioning units which may contain chloroflu rocarbons (CFCs) particularly RI 2 refrigerant which is conmnonly used in Tanzania for repair Works 4. The substation has no transformer oil containment to prevent oil from cont aninating the soil and ground water in case of spillage. Spare oil is stored in the above grourd tank which also has no any containment apart from gravels Environmiental Audit RXport - Final 37 I Reinrorcement and Upgrade of Dar es Salami, Kilimanjaro and At usba Transmission and Distribution System 5.

The substation is fenced and has waming signs to prevent the ge eral public from electrocutions 7. The substation has poor drainage which needs to be improved 8. The substation needs improvement in the following areas: i. Improvement in general cleanness of the substation and removal f scraps ii. Emergency preparedness, prevention and response plan needs t be prepared and rehearsed. A sumrnary of important items of the plan need to be anged on the wall for the reference of everyone iii. A toilet needs some repairs to be in a standard condition and a s urity guard kiosk is also needed. In addition, broken or missing cable trench slabs n ed to be replaced iv. Fire fighting equipment is inadequate need to be adequately suppl ed in the required proportions (foam, carbon dioxide, powder, etc.) and recharged w en expire v. Personal protective equipment such as helmets need to be supplie vi. Training of personnel is needed. One person attended a course 20 years ago but others have not attended any course vii. Improvement in waste handling viii. The substation needs more gravels ix. Work procedures and safety guidelines need to be available in a k iown language to 3 substation operators 3.20 Public Concerns (Substation) The major concem of the public regarding the substations was a he th risk due to electromagnetic effects. Although there is no proof yet of the effect here in 'anzania, people raised their fear based on the information available in the Intemet. Th World Health Organization (WHO) guidelines however, suggest that the level should not c xceed 5000V/m. There were no complains or concems about the noise levels around the substa ions. Up to now no any complaints have been received or reported to Substation authorities du ng the course of the study. Note: TANESCO shall perform a laboratory analysis of the soil samples under the transforrners suspected of PCBs in the year 2006 budget. When the fund becomes available a id the laboratory capable of delivering the required analysis locally is found the soil sarnples shal be taken for the analysis. 3.21 Prioritised Audit Findings and Recommendations Below are the prioritised audit findings and reconunendations.

Except for Njiro, Kiyungi, Ilala, and FZ III, which have askari kiosks and ilets majority of the substations, have no such facilities. Security guards have got neither shade nor toilets making their work difficult and dangerous in some cases such as rain s ason or at night. TANESCO is required to provide such facilities at the workplace for th convenience of workforce. It is reconomended thgat security guard kiosks and toilets shou d be constructed for those, whicl don 't have, and for those such as Sokoine city centre and Oyster Bay, which have the kiosks but toilets areout of order,should be restored and faintained 12. Working procedures and instructions are missing.TANESCO and subs ration Engineers shouldprepare work procedure manuals and instructions and make thei X available to all substation workers 13. Emergency preparedness, prevention and response plan was seen to e lacking in all substations audited in case of fire, major accident or major oil spills. Although some substations had radio calls and telephone lines no clear line of communi ation in case of emergency was seen. TANESCO needs to prepare an emergency responsc plan. The plan should be frequently practiced (hold regular drill to check whether the Ian performs as intended) and each employee should know all the information flow in case of the emergency. Informationflow charts should be posted at a visible place 14. Although training has been taking place in TANESCO, trainings specific illy designed for substation engineers, technicians and operators have been scarce and li ited to very few individuals. TANESCO (Head office which coordinates employeesr trainings in cooperation witl regionaloffices) needs to organiseregular courses (tail r made training programs to suit different cadres of substation employees and others) .su h as trainingon work procedures, health and safety matters, hazardous materialhandin P and emergency preparednessand response 15.

Environmental Assessment as a management tool could be used to identify t impacts before the construction of a substation. However, the audit assessment found no rec s showing that there was any envirornmental impact assessment for the substations. This may e due to the fact that majority of these substations were constructed more than 20 years ago wh EIA was given little attention. The audit study has identified the environmental impacts that a e likely to occur in the construction and operation of the substation. The significance of these impacts may be reduced if mitigation measures and monitoring are put in place. This ch qpter provides a summary of impacts, mitigation measures and monitoring plan. In order to ensure that there is a system to track compliance with the WB an( Govermnent of Tanzania policies; Laws and guidelines, TANESCO have to commit itself aId ensure that it establishes the Environmental Management System (EMS). The advantages of having the EMS at TANESCO include: having people who are responsible for ensurinn environmental management, having a systematic way of tracking the environmental problem and addressing them in all aspects of company activities, having proper records and assignm nt of budget to environmental programs. The project document for the EMS establishment within TANESCO is appended.

This amount of money shall be m de available by TANESCO. The costs are for the monitoring exercise staff from TANE CO head -office, Regional offices and National Environmental Management Council (NEMC) xperts, transport, laboratory and monitoring equipments. NEMC is included in the monito ng phase as an independent body with a given authority to monitor environmental compliance and according to the conditions of the environmental license. TANESCO is committed to follow the country's policies and continue to c mmunicate with relevant sectors and ministries to ensure that environment is protected and he Ith and safety of workers and people around our facilities is guaranteed. TANESCO shall prepare monitoring reports regularly and submit the sam to the relevant authority as require by EMA (2004).

Environmental Audit Reporl - Final 48 I Reinforcement and Upgrade of Dar es Saliam, Kilimanjaro and Ar sha Transnission and Distribution System_ Chapter 5 Conclusion and Recommendations The overall conclusion is that majority of the substations meet the Worl Bank minimum requirement with only few minor corrections. The remedial costs are to be co ered in Regional repair and maintenance budgets. It is proposed that Regional offices review the document to understand the shortcomings of the substations in their area and workout the ac ual budgets to be approved by the regional administration. It is the responsibility of TANESCO Regional Offices of which these substations fall in the area of their jurisdiction to ensure that they do corrective measures so as to fully comply with the World Bank minimum requirement. TANESCO Head Office shall provide assstance whenever necessary to the regional offices. 1. TANESCO should strengthen environmental management both Head Office Environmental Unit and at the implementing Regions or plants 2. Since TANESCO has so far no formalized Environmental Management ystem (EMS) in spite of having an environmental unit, which deals with environmenta1 matters. Then TANESCO has to develop an EMS suitable to its activities or adopt ISO 4000 standard in order to improve its environmental management performance. In ad ition, fund for implementing management plans should be made available 3. Although training has been taking place in TANESCO, trainings specific ly designed for substation engineers, technicians and operators have been scarce and l ited to very few individuals. TANESCO (Head office which coordinates employees' trainin ;s in cooperation with regional offices) needs to organise regular courses (tailor made train ng programs) to suit different cadres of substation employees and others. such as training n ay include work procedures, health and safety matters, hazardous material handling and emergency preparedness and response 4. Since it was observed that no clear identificatiorr of who has been assigned rcsponsibility of taking care for the environmental matters of the substations. Therefore, su station engineers or supervisors should be assigned also such a responsibility and rluired to report performance in monthly reports 5. TANESCO needs to prepare an emergency response plan in the event of fir , major accident or major oil spills. All audited substations didn't have the plan. Workers nec to rehearse and understand the inforrnation flow in case of the emergency so as to check vhether the plan works as intended. Information flow charts should also be posted at a visible place 6. Waste management need to be improved in all the substations as this mas soen to be a problem in most substations. Substation management should designate spec al areas (points) Eavimnrncntal Audit Repon - Fin,I 49 I Reinforcement and Upgrade of Dar es Salasm, KilIlmanjaro and Ar shs Transmnssion and Distribution System for waste collection before safe disposal. Special bins can be used to stor collected wastes such as pieces of cables, insulators and other wastes in the substation site b fore disposal 7. Raise awareness of people working in the substation on the potential hazarol of oil spill to the environment and how to handle it appropriately during refilling, oil filterin or maintenance. 8. TANESCO Regional Offices are required to provide toilets and askari kio k facilities in the substations for the convenience of workforce. There are some which nee repair and some which nced to be constructed. With exception of Njiro, Kiyungi, Ilala, a d FZ III all other substations lack toilet, askari kiosk or both. 9. TANESCO (Regional Offices) should collect all old transformers dumped t substation sites which some of them have oil leakage and dispose them or store them in ap ropriate designed areas that may contain or prevent the oil leakage into the soil. 10. TANESCO should provide adequate fire fighting equipment in a right prop rtion (foam, CO2 and powder) to fight any fire type in the substations and ensure that equip ent are regularly checked to be sure that they are working properly. Some substations h d inadequate fire fighting equipment or right proportion. II. TANESCO departments and substation engineers should prepare work p ocedure manuals and instructions where such instructions are very essential and make th m available in a known language to all substation workers. Many substations had no worki g procedures and instructions at all or had instruction written in a language not understandabl by majority. 12. TANESCO should provide resources estimated at least USD 11,000 anually to facilitate implementation of the proposed ESMP and monitoring plan. Other mitig ion costs will be covered in construction costs. 13. TANESCO Regional Offices should budget and urgently replace all lost r broken lids and slabs to improve the safety in the substations as some of the cable trench slabs were found broken or missing increasing a safety risks at night and in emergency cases. 14. TANESCO's substation engineers in collaboration with their Region Offices should reequip the First aid kits as required since most of first aid kits are n t equipped with essential drugs. 15. TANESCO should ensure that transformers identified having PCB cont ination (below 500ppm) are not moved from where they are located. In addition substatio engineers should ensure that there is no leakage to the soil or water. Further there should e appropriate oil handling at all times while waiting for the national strategic plan to elimin e POPs prepared by the Vice Presidents Office (VPO) 16. TANESCO should ensure that fences are repaired, security lights work g again and all danger signs replaced to alert people of the potential dangers as they approa h the fences Envirunmental Audit Report - Final 50 I I I i I I I Reinforcement and Upgrade of Dar es Salaani, Kilimanjaro and Ar sha Transmission and Distribution System - Bibliography I) Pollution Prevention and Abatement Handbook, World Bank Group, 1 98, pp 186-192, pp 436-440. 2) Intemational Finance Corporation, Environmental, Health and Safet Guidelines for electric Power Transmission and Distribution, 1998. 3) International Finance Corporation, Environmental Health and Safet Guidelines for Polychlorinated Biphenyls (PCBs), 1998. 4) Intemational Finance Corporation, Environmental Guidelines for Oc upational Health and Safety, Environmental and Social Guidelines for Occupational Heal h & Safety, June 2003. 5) The United Republic of Tanzania, the National Energy Policy, Minist y of Energy and Mineral, February, 2003. 6) SAPP, African Centre for Energy and Environment, Environmental A diting: Training Manual February 2004, Botswana. 7) UNEP Chemicals, Proceedings: Subregional Workshop on Managem nt of PCBs and Dioxins/ Furans, Arusha, Tanzania, November 2000. 8) SAPP, Draft SAPP Guidelines on the Management of Oil Spills, 2004 9) Stone and Webster Consultants, Tanzania Electric Supply Company Limited, Situation Assessment and Environmental Audit, Final Report Version 2.0 Power Sector Restructuring Project- Tanzania, 2004. 10)TANESCO, Emergency Power Project (EPP), Environmental audits o Thermal Power Plants - Songas Ubungo, IPTL Tegeta and TANESCO Nyakato Mwan ra, Final Report, June 2004. 11) Vice President's Office, PCB Inventory Project, Field Testing data s eets for Dar es Salaam, Arusha and Kilimanjaro, June-August 2004. 12) Lahmeyer Intemational, TANESCO Reinforcement and Upgrade of Dar es Salaam, Kilimanjaro and Arusha, Transmission and Distribution System, F asibility Study Report, 10 December 2004. 13) Wartsila Tanzania Limited, Guidelines for Employees, 2002. 14) Wartsila Tanzania Limited, Operation and Maintenance: A Guide to Saff y & Health 15)Songas Limited, Songo Songo Gas to Electricity project: Environ nental & Social Assessment and Management Plan, January 2001. 16) Songas Limited, SHE-Standard, January 2004. 17) National Environmental Management Council, Tanzania Enviro mental Impact Assessment Procedures and Guidelines Volume I through V, 2002 18) The Environmental Management Act, 2004, the United Republic o Tanzania, Act Supplement No. 3 of I Ithe February 2005.

Due to the nature of TANESCO's activiti s, there are always impacts on or from the environme t, which need to be considered during operation and dev lopment decision-making processes. There has been growing concern both nation lly and internationally for full incorporation of envir nmental protection in decision-making processes for economic activities. The approved National Environment I policy (NEP) and passed of the Environmental Manage ent Act, 2005 (It is unified environmental legislation to eal with the environmental issues). This Act is expected to become effective any time in 2005. All these requir every developer to achieve sustainable . developm nt that maximises the long-term welfare of both the pre ent and future generations of Tanzanian population. In order to comply with relevant legal and re gulatory requirements, TANESCO Is in process of establi hing its own Environment Management System (EMS). he EMS will ensure that environment is given ap ropriate consideration in all company development activ ies and decision-making processes. ES2: Objectives The following are the main project objectives: * To develop an appropriate corporate envir nmental policy, objectives and targets * To develop a system that will ensure that there is full integration of environmental considerati ns in all TANESCO's work and decision-making pro esses. . To establish a system that will ensure ontinual improvement of the environmental manag ment in TANESCO. * To demonstrate to public that TAN SCO - is protecting the environment in carrying out its activities. Finandng It is proposed that part of the funds to be provid d by The World Bank to finance the Transmission and Distribution Rehabilitation project (Dar es salaam Kilimanjaro and Arusha) isto be used also to fina ce a process of establishing the EMS in Tanzania Elect ic Supply Company Ltd (TANESCO). I I. I I ES4: Budget The total project budget is Five hundred nd Nine thousands six hundred and twenty eight Unit d State Dallas (US$ 509, 628) spread over a span of 5 y ars. It is anticipated that about US$ 257,520 will be utilise in phase I (first two years) and US$ 227,840 in phase II (the last three years). A contingency of US$24,268 Vas been included in the budget to cater for unforeseen ex enditure and escalation. ES5: Duration Five (5) years Phase I- drafting of company envir nmental policy. Phase II Implementation of the envir nmental policy ES5: Implementers The project will be coordinated and execute by the TANESCO'S Research and Development Departrn nt under Environmental Section with assistance of Di ision of Environment (DoE) and National Envir nmental Management Council (NEMC)) and individual outside TANESCO will be fully utilised in conducting r ieetings, seminars and education campaign to TANESCO e iployees, local and foreign environmental consultants where necessary. The Environmental Section, which is nder the Directorate of Corporate Planning and Research, as both capability and experience to carry out the work.

For that matter TANESCO has been spending substantial reso rces on EIAs and monitoring of the projects impacts on or from the environment. the There are several set backs to the present TANESCO approach of a dressing system fo dealing with environmental issues. Currently TANESCO has no established has neither environmental matters within the company. Furthermore, the companr environmental policy nor environmental objectives. More usually, environmental and considerations are integrated in donor-funded projects, mainly in the lanning hin ering power construction phase. Unless there is a direct environmental problem post generation or there is a donor support, TANESCO does not bother mu h about construction phase environmental problems. an As a remedy to the above set backs, TANESCO is in process of es ablishing (EMS). The EMS will form a frame ork through Environmental Management System company which all environment matters will be fairly addressed and integrated i all business, services and products. the In the Southern Africa Power Pool (SAPP), of which TANESCO is a ember, Environmental subcommittee (ESC) has been formed to advise the rnanagement related committee on environmental issues, keep abreast of regional and world ;isues on matters to environmental quality and also liase with their respective governmen s Some utilities in the region such as ESKOM o South Africa pertaining to environment. nt System to and ZESCO of Zambia already have their own Environmental Managem well with the take care of the environmental matters and are in good position to cope African new developments. The Environmental subcommittee (ESC) of the Sou hern aim f improving Power Pool (SAPP) has conducted environmental workshops with the an active environmental awareness among the regional power utilities. TANESC as keep pae with other member in the Southern African Power Pool (SAPP) has to regional utilities by developing and implementing EMS. 1.2 PREVIOUS WORK iderations in TANESCO recognised the importance of integrating of environmental con ONMENTAL its activities in 1996 when it formally accepted a proposal for an ENV ORPLAN. In MANAGEMENT SYSTEM prepared by the consultants for the PFRP, IVO- orkshop on April 1996, TANESCO In collaboration with NEMC organised a NZANIA" at "ENVIRONMENTAL MATTERS RELATED TO POWER PRODUCTION IN anagement Hale. At this workshop the then proposed TANESCO Environmental System (EMS) was discussed and its implementation recommended. I ~spre...A.4f i i TANESCO's Field Studies Unit by then now the Research and Developme t Department In cooperation with IVO INTERNATIONAL of Finland prepared a d ailed project document entitled: DEVELOPMENT OF ENVIRONMENTAL MANAGEMENT SYSTEM FOR TANESCO in 1997 - 99, for soliciting of funds for implementation of EM . The project never started, because 1996 was a bad financial year for TANESCO an FINNIDA did not approve the requested fund. Since then TANESCO tried to solicit funds from different donors and inter ally but up to date no substantial amount of fund is provided. In 2001 during the Kiha si Spray Toad saga the Lower Kihansi Environmental Project (LKEMP) financed by Aprid Bank set aside US$ 65,000 to help TANESCO in the process of establishing its own EMS. So far a study tour to ESKOM and ZESCO for 5 staff 1 from Kihansi Power Pla t and 4 from Directorate of Corporate Planning and Research has been done, with ma n objective of gaining a knowledge and experience on establishing and implementing a EMS in power utilities. This proposal therefore include foreign assistance, be it finance or t chnical, It is proposed that financing is to be covered by the World Bank thro gh proposed Transmission and Distribution Rehabilitation Project and the technica part will be carried out by TANESCO staff in collaboration with local and foreign nvironmental consultants as far as necessary. SAPP member utilities that have EMS riay be visited and consulted for advice. 2.0 PROJECT PURPOSES AND OBJECTIVES 2.1 PROJECrPURPOSE The main purposes of this work are: * To prepare the company environmental policy and set objectiv es and targets * To establish a system within TANESCO that will ens re planning, implementation, reviewing and continual improvement (i.e. E S). 2.2 PROJECT OBJECTIVES The main objectives of this work are: * To establish a system that will ensure continual improve nent of the environmental management in TANESCO. * To develop and establish an effective EMS within TANESCO * To ensure that there is full integration of environmental consid rations in all work processes, planning and execution of all TANESCO activitie!. * To demonstrate to public that TANESCO is protecting the environm nt in carrying out its activities. 1w,-. iI I I 3.0 PROJECT ACTIVITIES, RESULTS AND MAIN ASSUMPTIONS 3.1 PROJECTACTIVITIES The following are the main project activities: PHASE I TANESCO, .

These include the British Standards Institute, Canadian Standards Association European Community ('Euro-Audit'), the Canadian Chemical Produceis nmental Code (Responsible Care Program), the Canadian Petroleum Association (Envirc al Standards of Practice) and the International Standards Association (ISO). Intemati ment system Organisation (ISO) has developed a series of environmental manag worldw de as national standards, which have been adopted by more than 100 countries standards and have proved to be successful. ed in the ISO In establishing and implementing TANESCO EMS, recommendation contai 14000 series will be followed, i.e. preparatory review, drafting f policy and of all activities f r establishing implementing the policy. Phase I of this work will consist fulfilling the the EMS i.e. preparatory review, drafting of the policy and planning fc in which all planned a ivities will be policy. Phase II will be an Implementation phase executed. 4.2 DRAFTING OF CORPORATE ENVIRONMENTAL POLICY the first Because TANESCO does not have a formal environmental management sw stem, step will be to establish the current position with regard to the environmental I management by means of a preparatory review. The preparatory revie v will identify the environmental aspects arising from the organisation's past, existing r planned ac- tivities, products or services. It will also examine all existing environmental management practices and procedures, legal requirements and previous incidents and non- compliance. The review will establish the main impacts due to TANESCO activities and the current means of dealing with them. This will form a base for i entifying the priorities to be addressed in the environmental policy. Few field trips o generating stations, transmission and distribution lines, on going projects etc. wil be made to confirm results of the review and to collect additional reports and inforn ation. This work will involve drafting of an appropriate corporate environmenta policy that is current and consistent with overall corporate priorities, managemen philosophy, practices and environmental legal requirements and obligations. It will in olve utilising results from the preparatory review and current guiding principle for impl mentation of EMS. Since formulation of the corporate policy is the heart of the whole exercise, the three months time will be allocated to the management to read and cor iment on the draft environmental policy. The final policy statement and managemen commitment statement are expected to be ready in three months time after receivi g comments from management. Environmental Unit will do the preparatory review of drafting of corporate nvironmental policy in collaboration with local or foreign consultant. Consultatio with other stakeholder's i.e. government environmental bodies, NGO's, affected pe ples on some issues might be necessary. 4.3 PLANNING FOR FULFLLING THE COMPANY POLICY For fulfilling the environmental policy, appropriate corporate environmen al objectives and targets will be established and environmental programs (environn ental quality control, monitoring and auditing etc.) documents prepared. The ways f integrating environment management into the company structure will be chat ed out and responsibility clearly defined. Approval of the management is required a this stage to make sure that the proposal is acceptable and is not in any way conflic ing company structure expansion plan. Parallel to preparation of the environmental programmes, training nee s programs; schedules and budget will be established. It is expected that the traini g will target three groups; the management, Research and Development (Environme tal Unit) and general staff, each category receiving training according to the role each roup plays in the implementation of EMS. Another important task to be accomplished in this phase is prepa tion of the environmental management system documentation, communication and r cords control systems. A two-way interactive information flow and reporting system, hich Involve I input from each and every staff at his working station meanwhile allowin appropriate data collection and analysis, interpretation and decision-making, will be c attered out. For smooth implementation of the EMS, the training of management and key research and development staff in environmental management will start in thi phase and extended through the implementation phase is important. Details on the training requirements are presented in section 5. A final draft EMS report will be submitted to the management for approval at the end of this phase. The draft report shall contain the corporate environmental polic y, objectives, targets, budget and schedule for implementation. Planning and drafting of the environmental programmes will require inputs from different experts. It is therefore expected that in this phase extemal exp rtise, mainly from UDSM, NEMC, DoE and appropriate NGOs will be required. The prog ammes need to be discussed in the workshops and comments incorporated prior to th ir adoption. 4.4 IMPLEMENTA TION OF EMS The Implementation of the EMS will consist of all activities that will facilita integration of environmental policies and programmes Into TANESCO strategic plans, ractices and activities. The objective of this phase will be to align TANESCO structure employees, systems, strategies and resources allocation towards achievement Df company environmental objectives. The main activities to be carried out under thi phase are: Training, educating and motivating employees to conduct their a tivities in an environmentally friendly manner and aiming at achieving company e vironmental objectives, goals and targets. This will involve conducting e vironmental meetings and seminars for disseminating education and awarenes to TANESCO personnel in the head office and in the operation regions and distr , all hydro and thermal systems and transmission line teams around the cou try. Follow up of allocation of appropriate human, material (facilities an Iequipment) and financial resources essential to the implementation f company environmental policy and achievement of objectives.

TANESCO st ould ensure ITC Holland, ICH of Norway are of meaningful that executing staff, management and even operational staff attend thes Xcourses. Trainers and facilitators need to be equipped with appropriate skills anc knowledge either in Tanzania or abroad. The best option would be to have a trip In the region such For as South Africa and Zambia or other SAPP countries to learn from their ex erience. engaged in environmental issue s, long term staff who are expected to be permanently courses abroad are recommended. 5.4 EQUIPMENTTAND MA TERIALS and Through TANESCO's major projects namely; PFRP, Kihansi and Power VI, Research The Development department has acquired equipment for field studies and offic! works. available equipment are enough for carrying out site investigatior for dams, transmission lines, substations and shallow foundations. Also water qualit analyses kits have been acquired. But due to the age and new technology some of th equipments like Decibel Meter, Air quality equipment, PCBs test kits, GPS, Digital camera and Equipments to measure radiation from electromagnetic waves have to b bought. Recently there is growing laboratory testing capacity in the country. Te ting facilities available at UDSM, Maji, materials Ujenzi, EAMRDC and elsewhere wil be used for testing the samples. 6.0 BUDGET AND SCHEDULE 6.1 BUDGET The budget for developing and initiating implementation of the EMS s about four hundred and seventy thousands US$ (US$ 509,628) as shown on Anne II. 6.2 SCHEDULE The development of the EMS will take about 2 years and initiation of the in iplementation will take about 3 years.
