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 enacted2005 EMA implementation started

Contd Environment MgtEMA2004 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

OIL&NATURAL GAS RESOURCESThese 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

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

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

DRILLINGExploratory 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

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%

NATURAL GAS ADAPTATION&MITIGATIONNatural 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

STRATEGIC ENVIRONMENT ASSESSMENT(SEA)&SDCoordinated 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

ESCBP to be Funded by World BankThe 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
