Study of Environmental Monitoring Practices at Warri Refinery Marine Terminal

Industrial marine terminals associated with petroleum refining operations present significant potential for environmental contamination through vessel operations, pipeline transfers, and terminal maintenance activities. This study examines the environmental monitoring practices at the Warri Refinery and Petrochemical Company marine terminal in Delta State, assessing the adequacy of monitoring systems for detecting and managing marine pollution. A descriptive case study design was adopted, with data collected through structured interviews with terminal environmental officers and marine operations supervisors, physical inspection of monitoring equipment, and review of environmental monitoring reports for the period 2021 to 2024. The study applies the standards of the National Environmental Standards and Regulations Enforcement Agency and MARPOL as the compliance benchmarks. Findings indicate that the terminal conducts periodic water quality monitoring at designated sampling points, but monitoring frequency is below the recommended quarterly minimum due to equipment downtime and staffing constraints. Automated oil detection sensors on the jetty apron have been out of service for extended periods without replacement. Incident response documentation is incomplete, with several minor spill events not formally recorded in the environmental incident register. Recommendations include restoration of continuous oil detection monitoring at the jetty, training of terminal staff in environmental incident documentation procedures, engagement of an independent environmental auditor, and adoption of a dedicated terminal environmental management plan aligned with NESREA standards.
