  1. OVERVIEW OF ENVIRONMENT MGT IN OIL&GAS SUB-SECTOR Presented by Eng. James L. Ngeleja Principal Environmental Management Officer-NEMC

  2. National Environment Management Framework • National CONSTITUTION-Clean Environment for ALL Tanzanians • Since 1995 VPO is CHARGED with Environment Management national-wide • 1997 National Environment Policy established. • 2004 EMA –A framework legislation enacted • 2005 EMA implementation started

  3. Contd Environment Mgt • EMA2004 Mandates NEMC on EIA processes, Environmental Compliance and Enforcement, Research, Awareness. • VPO-DoE Charged with Overall Environment Management Coordination and Strategic Environmental Assessment • EMA2004 Require sectors to manage environmental issues in their respective sectors

  4. OIL&NATURAL GAS RESOURCES • These are finite resources that need to be managed and regulated carefully in order to benefit ALL Tanzanians. • Environment impacts in Oil& Gas are in both Upstream/Mid and Downstream • UPSTREAM-Exploration (seismic surveys-off/on shore) • Mid stream (Gas processing) • Downstream(Transmission, power uses-e.t.c

  5. NATURAL GAS PRODUCTION-UPSTREAM • Exploration is both in marine & Terrestrial environments • Marine—Deep Sea Exploration e.g Zafarani, Lavani, Njuani • Terrestrial– Lakes Tanganyika; Nyasa; Rukwa & Natron, Mukuranga

  6. SEISMIC SURVEYS(Project level) • These surveys are conducted in both marine and terrestrial and have environmental impacts. The surveys are investigations on the sub-surface for geo-physical information and data • Marine seismic surveys use seismic air guns. Potential environmental impacts include coral reefs,e.t.c • Terrestrial/on-shore surveys have environmental impacts e.g land uses; biodiversity loss • The use of environmental sensitivity maps is crucial

  7. DRILLING • Exploratory drillings are follow up operations after seismic surveys and have significant environmental impacts • Drilling operations introduce a wide range of complex chemical compounds to the environment. These are drilling fluids that could be oil-based, synthetic and water-based. These fluids circulate in the borehole to control temperatures and pressure as well as lubricating the drill bits and removing the drilling cuttings. • One production platform can discharge 60-70ton/day

  8. NATURAL GAS POWER GENERATION • Natural Gas is environmentally friendly globally • Natural gas is both for Adaptation and Mitigation to address Climate Change • Natural gas utilization in Tanzania plays a significant role of adaptation • In 2001, natural gas contributed 40% of power generated, hydro 41% imported oil 19%

  9. NATURAL GAS ADAPTATION&MITIGATION • Natural gas plays a role in the national power mix along side hydro,thermal(oil) and at small extent biomass • Natural gas offers business opportunity in the carbon market-Example:Mtwara Power Plant/FormerArtumas-Wenceworth whereby about 7000tons carbon per year are bought by Dutch Govt in climate mitigation • Natural gas is versatile for small cogeneration applications-Example:TCC,Urafiki Textiles

  10. Downstream Oil and Gas Environmental Management • Key Regulatory Institutions • NEMC—EIA Reviews, Environmental Monitoring • OSHA– Occupational Healthy and safety • EWURA—Licences, Price Regulation • TPDC—Sector Development • MEM—Overall Sector development • TBS---Standards for compliance

  11. STRATEGIC ENVIRONMENT ASSESSMENT(SEA)&SD • Coordinated by VPO-DoE,SEA is a systematic process for assessing/evaluating environmental,social,economic& health impacts of a policy, regulation,plan,strategy &bill • SEA ensures that environmental, social &economic aspects are integrated in implementing a sector initiative such as the oil& gas in order to achieve Sustainable Development(SD) • SD means development that meets the needs of present generation without compromising the ability of future generation to meet their needs

  12. ESCBP to be Funded by World Bank • The Project Objective—Capacity building to regulatory institutions in areas of best environmental management including SESIA • Skills development • Support to PPP in natural gas development—due to its intensive capital requirement
