Chapter Eight Conclusion and References 8.0 CONCLUSION CHAPTER EIGHT This Environmental Impact Assessment (EIA) report was prepared adopting a multidisciplinary team approach consistent with the FMEnv Sectoral Guidelines for Oil and Gas Projects and the DPR’s Environmental Guidelines and Standards for Petroleum Industries in Nigeria. The EIA study involved detailed literature search, field observations and in situ measurements, field sampling, laboratory and data analyses, impact identification, evaluation and reporting. The WDGSP/WAGP at Oben Field presents opportunity to monetize SPDC gas and secure the company’s ‘Licence to Operate’ (LTO) in Nigeria by developing existing gas resources and facilities to satisfy the gas purchase agreement (GPA) signed with N-Gas for the West African Gas Pipeline (WAGP) project, whilst maintaining supply/demand balance for existing gas contracts and commitments in the western domestic gas network in Nigeria. The Oben Gas Plant has the flexibility to support the low-pressure customers as well as supply at higher pressures to the ELPS and the Ajakouta Power Plant. Among other things the project is intended to: meet contractual gas demand of the Western Domestic Gas Market, secure additional sources of gas supply to the proposed West African Gas Pipeline (WAGP), develop large gas reserves and enhance SPDC reputation as a reliable gas supplier. The WDGSP/WAGP at Oben Field is thus designed to ensure optimal utilisation and recovery of the huge gas deposits within the Oben Field. This will, in addition to increasing the national gas reserves, increase the national foreign earnings as well as boost SPDC gas production target. The project will also create employment opportunities and consequently increase the standard of living of many Nigerians. However, the EIA report has highlighted the potential and associated adverse impacts on the environment. These impacts are mainly short-term, residual, highly localized and reversible on the immediate environment. Also some aspects of the project are expected to elicit positive impacts on the environment. The EIA recommends that such positive impacts should be sustained and enhanced. Mitigation measures have been proffered for each of the identified potential and associated adverse impacts of the project. Also, an Environmental Management Plan (EMP) has been developed to ensure that the identified potential impacts can be reduced to “as low as practically reasonable” (ALARP). Most importantly, monitoring programmes and environmental auditing of the project have been recommended throughout its life span. This is to ensure that all impact indicators for the various environmental components at every phase of the project are within statutory limits. 8-1
