Good govemance, good policies, investor ' confidence and economic recovery programmes have stimulated the economic growth and sc cial activities. In 1986, Tanzania introduced and embarked on Economic Recovery Programme (E RP) backed by a I series of IMF inspired structural adjustment programmes. ERP concentrat d on reforming agriculture, opening up the private sectors, deregulating food marketing, libe ralized trade and lifting foreign exchange controls. These programmes have resulted into urb nization and the I growth in mining sector. The implication of these programmes to TANES O has been the increase of a number of customers in major cities in need of electricity conn ctions. However, most of the infrastructure have reached their capacities and cannot allow c nnection of new ii |customers unless they are rehabilitated. The most affected are the substations and their voltage carriage lines located in Dar es Salaam, Arusha and Moshi town centres. l Tanzania's economy still faces considerable difficulties and many necessary r forms remain to be implemented. It is important then for TANESCO and the Government of Ta nzania to support the industrial sector recovery by preventing frequent power outages and impro ie power quality. This involves putting new investment in distribution systems and development f new sources of electricity. In Tanzania, only about 11% of the population (34million)' enjoys the ele tricity. The total number of customers (residential, industrial and commerce) connected by the nd of June 2005 was 570,665 with average growth of between 6-9% since year 2000.2 In terms f generation, the total available installed capacity is 890MW. The sources include TANE SCO (590MW), SONGAS (200MW), and the Independent Power Tanzania Limited-IPTL (1001 4W). TANESCO also imports power from Uganda and Zambia for Kagera region and Tunduma, Sumbawanga and Mbozi towns respectively. l TANESCO has a number of substations scattered all over the country. Some s bstations are for the stepping-up from e.g. l1kV to 220kV using 11/33/66/132/220kV conver ion transformers and some are step-down substations which reduce the transmission voltage into distributien I voltage, say from 220kV to 1 kV. This environmental audit study was condu ted on some step down substations ranging from 220/132/33kV to 33/1 1kV. I In 2002, TANESCO in collaboration with Japanese International Cooperatio Agency (JICA) .. prepared a Master Plan to improve the power systems in major towns o Dar es Salaamn, Kilimanjaro and Arusha. The current power demands for these regions are on iverage 240MW, 30MW and 38MW respectively.3 The Master Plan outlines areas of priority and investments needed to solve the frequent power outages experienced in major cities. Fu ther, TANESCO 12002 census 2source TANESCO 3 Source TANESCO, data up to May 2005 _ Environmnental Audit Report -Final  I  | Reinforcement and Upgrade of Dar es Salaam, Kilimanjaro and Ar sha Transmission and Distribution System 3 l undertook several studies including Relief Project 2 done by NetGroup Solu ions (Pty) Ltd of South Africa in 2004 and feasibility study on the Reinforcement and Upgrade f Dar es Salaam, l Kilimanjaro and Arusha Transmission and Distribution system done by Lahm yer Intemational of Germany in September 2004. All these studies identified areas of pri rity and type of investment needed by TANESCO to improve the transmission and distribution ystems. l Based on the above-mentioned studies, TANESCO consulted various fi anciers to seek assistance in implementing different components of the Master Plan. The Wo Id Bank (WB) as one of the contacted financiers showed interest in supporting TANESCO in t at respect. Hence I TANESCO and the International Development Association (IDA)/World B k are currently preparing a distribution rehabilitation and transmission reinforcement compo ent as part of the Songo Songo Gas Development and Power Generation Project (Credit 3569- A). The amount under discussion with the WB is about US$ 57 million. l 2.0 The Project The proposed project to be owned by TANESCO and co-financed by the W rld Bank and the Nordic Development Fund (NDF) at an estimated cost of 70m USD consists of wo components: The first component involves the rehabilitation of 18 existing substation at Oyster Bay, Mikocheni, Msasani, Factory Zone I, Factory Zone II, City Centre, Factory one III, Sokoine, Kurasini and Ilala in Dar es Salaam. Others are Mount Meru, Unga Ltd., Kilt Ltd, Themi and Njiro in Arusha and Boma-Mbuzi, Trade School and Kiyungi in Kilimanjaro region. These 18 substations out of all substations in Dar es Salaam, Arusha and Kilimanjaro h ve been selected for the rehabilitation because they are located in the areas with fast growing p wer demand and the systems have reached the capacity limit hence they are overloaded. Furth r there will be a repair and upgrade of the 11/33 kV distribution systems. This rehabilitatio of Distribution l Facilities involves: * Supply and installation of 22 additional 15MVA, 33/llkV transform - rs to relieve the overload in the existing substations (i.e. replacing low capacity transfo ers e.g. 5MVA with medium capacity of 15MVA transformers) * Supply and installation of about 33, 33/llkV circuit breakers and 24 llkV circuit breakers with associated switchboards I * Supply and installation of 50MVA 132/33kV transformer with a ircuit breaker at Kiyungi, Njiro, and Kurasini Substations. ;-| * Supply of materials and equipment for repair/upgrading of the distributi n systems which . | make a provision for the following: reconductoring, protection syste ns, auto-reclosers and auto load break switches, SCADA, section analysers, boosters, ligh ening protection, 13 distribution transformers, new 33/1 1kV lines and statistical metering Upgrading of substations means replacement of power transformers by a hi her rated power transformer and its associated breakers. This will involve mainly upgrading of he foundations to a higher bearing capacity, thus necessitating having temporary measures in pla e to avoid power outages. * The second component involves the construction of new 132kV trans nission lines that will connect the Ubungo Main substation with upgraded 132/33kV Oys er Bay, Kurasini, Environnmntal Audit Report -Final ii  I  l'I Reinforcement and Upgrade of Dar es Salaam, Iilimanjaro and Ar sha Transmission and Distribution System Mbagala, Factory Zone II (Gongolamboto), Kinyerezi and Factory one III (Kipawa) substations. Also component two involves the construction of addition- I Kiyungi - Njiro l 132kV transmission line. 2.1 Project Objectives The project will achieve the following objectives: X * Reducing the duration and frequency of power interruptions * Improving voltage conditions at consumers' premises * Reducing the power system losses * Improvement in marketing by facilitating the possibilities of connecting more customers * Improvement of TANESCO image to the public (less complains from cl istomers) l Attraction of more revenue for the company * The project will contribute to the effort by the Tanzanian Government of improving the livelihood of ordinary Tanzanians through the National Strategy for the Growth and Reduction of Poverty in Tanzania (MKUKUTA) Component 1 of this project requires a comprehensive Environmental Audit A ssessment (EAA) I which is reported in this report while component 2 has separate comprehensiN e reports namely; Environmental Impact Assessment (EIA and SIA) and Resettlement Action Pla i (RAP). l 3.0 The Purpose of the Environmental Audit Assessment World Bank requires that all investments comply with the World Bank Safes uard Policies and * Environmental Guidelines as presented in the Pollution Prevention and Aba ement Handbook (1998) and IFC Environmental Guidelines. It is also a Tanzanian requiremer t that all projects l should undertake the Environmental Assessment before the implementatio . The Tanzanian Environmental Management Act (2004) section 81(1-4) stipulates that it is the obligation of the project proponent to undertake environmental impact assessment study of the p oject. * Hence, for this study the following major guidelines and policies will be appli d: Electric Power Transmission and Distribution guidelines (IFC), Occupational Health & Safety (IFC), and Natural Habitat (OP 4.04) because of potential oil pollution. Additionally, nat onal requirement as reflected in various Tanzania's sectoral policies, the National Environrrent Management Council (NEMC) Environmental Impact Assessment Guidelines (2002 apdate) and the Environmental Management Act (2004). The purposes of the Enviromnental Audit Assessment are: l To identify present inadequacies in environmental management, and o cupational health and safety issues in the facilities to be rehabilitated. Of particular interc st are the present pollution if any and its potential clean-up costs 0 To determine the need for remedial actions necessary to bring the sub. ect facilities into compliance with World Bank Safeguard Policies and 0 To recomrnend actions to be taken to improve and strength n TANESCO's environmental, health and safety management i l Environnrintal Audit Report -Final iii I  I  Reinforcement and Upgrade of Dares Salsam, Kilimanjaro and Ar isha Transmission and Distribution System J 3.1 Scope of Work The Environmental Audit Assessment focused only on the 18 existing substati ns earmarked for rehabilitation in Dar es Salaam, Arusha and Kilimanjaro as outlined above plus one additional substation at Chalinze in Coast Region. The Audit took place in November and December 2004. 4.0 Methodology and Approach To accomplish the audit assessment the following approach was applied: 4.1 Reviewing records and relevant documents All available relevant in house documents were reviewed. The documents i clude: the Master Plan Study on the Power Sector for Major Towns in the United Republic of Tanzania (2002) by EPDC of Japan; Reinforcement and Upgrade of Dar es Salaam, Kilima jaro and Arusha Transmission and Distribution System Feasibility Study Report (200 ) by. Lahmeyer International; Environmental Management Act (EMA -2004); NEMC s Environmental Guidelines (2002); various Tanzanian sectoral policies; World Bank .Operatior at Policies; World Bank, (IFC) Pollution Prevention and Abatement Handbook; environmental and occupational health and safety guidelines and standards. These documents formed a founda ion of conducting this environmental audit through a checklist. The checklist identifies issue as per the following criteria as deduced fr m the guidelines mentioned above. * General environmental management; l * Waste management practices; * Hazardous materials management; * Groundwater and soil contamination control; X * Occupational health and safety management; and * Noise management (Noise level measurements were taken in some su stations to get an 3 overview of the noise levels in the substations) 4.2 Site Observations and Interview All 18 substations in Dar es Salaam, Kilimanjaro and Arusha were visited for ssessment plus an additional one at Chalinze. Consultations with NEMC and Municipal auth rities were made before the site visit. Also during the site visit, interviews and brief meetings ith relevant staff l and residents around the substations were conducted. 4.3 Use of secondary data l Due to resource constraint, this assessment used available data and laboratory test results for identifying polychlorinated biphenyls (PCB) in transformers and switchgeirs conducted by previous studies in the same substations. The studies include Situation Assessment and Environmental Audit, Power Sector Restructuring Project- Final Report Versi n 2.0 prepared by Stone & Webster Consultants, May 2004 and Inventory of Electrical Equipn ent Suspected to Contain Polychlorinated Biphenyls (PCBs) prepared by the Vice Presidents Of ice June 2004. 4.4 PCB identification methods The PCBs identification methods used in this study include: Environmental Audit Rcport -Final iv  I I  Reinforcement and Upgrade of Dar es S2aaa, Kilimanjaro and Artsha Transmission and Distribution System l l ~~~Manufacturer's narneplate informnation; Elimination method cut off year assur ed 1980; Density test; Chlorine frame test; Dexsil test kits; and Laboratory testing (gas chromatogr phy with electron capture then comparing results against standard chromatograms for known arochlors). Transforner found to contain concentration of less than 50ppm of PCB was lassified as PCB free. Equipment found to have 50ppm or above but below 500ppm vras classified as l contaminated. Equipment found to contain 500ppm and above of PCBs is classi fied as pure PCB. 4.5 Findings evaluation l Through field observations, site screening tests, laboratory analysis, checklist and professional judgment the audit findings were evaluated and prioritized as of high, mediui or low concern depending on the severity of the problem and health, safety or environnen al impact it may cause. 5.0 Report format * This environmental audit report comprises of five chapters, introduction o the project and methodology; legal framework; baseline information and the audit findinE s; environmental management plan & monitoring; and conclusion and recommendation. The rep rt has appendices that include location map of substations, photo documentation, PCB laboratory results of some substations, the criteria checklist of audited substations and list of consulted pe ple. 6.0 Public Concern The major public concern was a health risk due to electromagnetic effect. No n ise complains or I concerns were reported during the survey. I | 7.0 Remedial Costs The identified weaknesses are small and could be covered in region's repair and maintenance budgets. Regions need to provide the remedial budgets as appropriate so t at the costs are included in the annual budgets for approval. Note: Laboratory analysis of the soil sarnples under the transformers susp cted of PCBs is awaiting the budget. When budget is secured soil samples will be sent for the la oratory analysis. 8.0. Training Needs 3 It is proposed that as part of this project, training should be considered foc sing on capacity building of the environmental unit in areas of Environmental Audit, Social Imp ct Assessment & management, health and safety awareness seminars and work procedure for Substation l engineers, technicians and operators. The anticipated cost for the training and quipment for the year 2006 is about USD 69,300. l 9.0 Environmental Management Plan (EMP) Environmental Management Plan (EMP) and monitoring have been included. E dP has identified environmental impacts and their mitigation measures. Monitoring plan has sti ulated indicators I to be monitored and required resources to ensure that mitigation measures ar implemented. It important that TANESCO provide resources estimated to be USD 11,000 annu lly to implement the EMP as shown on the plan. Environmental Audit Repon -Final v  - - ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~  Reinforcement and Upgrade of Dar es Salaam, Kilimanjaro and Aru ha Transmission and Distribution System I 10.0 Major Audit findings and Recommendations Below are the recommendations following the audit findings. Correction o these observed 3 weaknesses and shortcomings is important so as meet the minimum World Ban; requirement: * High Priority 1. TANESCO should ensure that transformers identified having PCB cont mination (below 500ppm) are not moved from where they are located. In addition substation -ngineers should I ensure that there is no leakage to the soil or water. Further there should b appropriate oil handling at all times while waiting for the national strategic plan to elimina e POPs prepared by the Vice Presidents Office (VPO) 2. Although training has been taking place in TANESCO, trainings specific illy designed for substation engineers, technicians. and operators have been scarce and lim ted to very few I . 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 l 3. Since it was observed that no clear identification of who has been assigned responsibility of taking care for the environmental matters of the substations. Therefore, sub tation engineers or supervisors should be assigned also such a responsibility and re uired to report performance in monthly reports 4. Waste management need to be improved in all the substations as this was seen to be a * problem in most substations. Substation management should designate spec al areas (points) for waste collection before safe disposal. Special bins can be used to store ollected wastes 3 such as pieces of cables, insulators and other wastes in the substation site bef )re disposal 5. Raise awareness of people working in the substation on the potential hazard f oil spill to the l l environment and how to handle it appropriately during refilling, oil filtering r maintenance. l 6. TANESCO Regional Offices -are required to provide toilets and askari kios facilities in the substations for the convenience of workforce. There are some which need repair and some which need to be constructed. With exception of Njiro, Kiyungi, Ilala, and FZ III all other substations lack toilet, askari kiosk or both. 7. TANESCO (Regional Offices) should collect all old transformers dumped a substation sites which some of them have oil leakage and dispose them or store them in appr priate designed areas that may contain or prevent the oil leakage into the soil. * 8. TANESCO should provide adequate fire fighting equipment in a right propo tion (foam, C02 and powder) to fight any fire type in the substations and ensure that equipm nt are regularly checked to be sure that they are working properly. Some substations had inadequate fire fighting equipment or right proportion. Environmental Audit Rcport -Final vi  I  - - - Jrp I I Reinforcement and Upgrade of Dar es Salaani, Kiimanjaro and Aru ha Transmission and Distribution System 9. TANESCO should provide resources estimated at least USD 11,000 ann ally to facilitate implementation of the proposed ESMP and monitoring plan. Other mitiga ion costs will be covered in construction costs. 10. TANESCO Regional Offices should budget and urgently replace all lost o broken lids and l slabs to improve the safety in the substations as some of the cable trench labs were found broken or missing increasing a safety risks at night and in emergency cases. l 11. TANESCO's substation engineers in collaboration with their Regiona Offices should reequip the First aid kits as required since most of first aid kits are n t equipped with l essential drugs. 12. TANESCO should ensure that fences are repaired, security lights worki g again and all danger signs replaced to alert people of the potential dangers as they approa h the fences Medium Priority l 13. 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 nee to rehearse and understand the information flow in case of the emergency so as to check Nhether the plan works as intended. Information flow charts should also be posted at a visible place 14. Since TANESCO has so far no formalized Environmental Management ystem (EMS) in spite of having an environmental unit, which deals with environment 1 matters. Then TANESCO has to develop an EMS suitable to its activities or adopt ISO 1 000 standard in order to improve its environmental management performance. In ad ition, fund for implementing management plans should be made available 15. TANESCO should strengthen environmental management both a Head Office Environmental Unit and at the implementing Regions or plants l 16. TANESCO departments and substation engineers should prepare work pr cedure manuals and instructions where such instructions are very essential and make .thein available in a known language to all substation workers. Many substations had n-o workin procedures and instructions at all or had instruction written in a language not understandable by majority. Overall TANESCO Management Response I TANESCO acknowledges the corporate responsibility and shall take correctiv measures of the identified environmental and health aspects. The work and budget will be i cluded in the company's business plan and eventually incorporated in the Company E vironrniental Management System (EMS). TANESCO is committed to follow the country's policies and continue to comn unicate with relevant sectors and ministries to ensure that environment is protected and hea h and safety of workers and people around our facilities is guaranteed.
