7 3.6.2 ENVIRONMENTAL PROTECTION a) There shall be a detailed Environmental Impact Assessment (EIA) study of the area as provided for in the National Environmental Guidelines and Standards for the Petroleum Industries in Nigeria (EGASPIN) as issued by the DPR before commencement of construction. b) The general layout of the location and provisions for all waste disposal in the refinery/ plant shall comply with the applicable specifications in the EGASPIN c) The refinery / plant shall be equipped with adequate provisions for containing and handling spills and accidental discharge of potential contaminants. d) All the systems and components of the plant / refinery shall be designed to withstand any anticipated extremes of environmental phenomena on location. e) The provision of effluent and recipient water quality monitoring shall be in accordance with the EGASPIN 3.6.3 SAFETY FACTORS a) All offices, warehouses and process buildings shall be constructed with utmost consideration for the safety of the workers and equipment. Laboratory building construction shall take into consideration the safety of personnel and provision of adequate ventilation as well as that for proper disposal of waste. b) Material Safety Sheet (MSS) shall be prepared in respect of all potentially hazardous chemicals and materials. c) Emergency alarm system and evacuation programs shall conform to Standards Industry Practice to the satisfaction of the Honorable Minister. d) The noise level at any point in the refinery emanating from engines and fluid velocities in the piping shall not exceed 90dBA. Where this level is to be exceeded, wearing of ear protection device shall become mandatory. e) The flare stack shall be located at a distance of at least 60m (200ft) from the unit or storage tanks and the flare shall conform to the approved limit of atmospheric emission. f) The automatic control system for emergency shutdown of all strategic or critical equipment in the refinery / plant such as columns, fired heaters, separators, surge vessels, pipeline and manifolds compressors and pump discharge headers shall be based on fail-safe logic designs. g) Fire sensors and gas detection and alarm system shall be installed at strategic points of the refinery and its offsite facilities. In addition, adequate fire mitigation systems shall be provided at all identified fire risk areas of the refinery. 3.6.4 HAZARD AND OPERABILITY REVIEW (HAZOP) Petroleum Plants designs shall be subjected to SAFE Chart and HAZOP reviews at the following stages of the design and development. 1) At the completion of the plot plans and engineering models. 2) At the completion of the detailed engineering design and specifications. Accredited representatives of the department shall be present at these SAFE Chart and HAZOP reviews. It shall be mandatory for each of these stages of engineering design successfully scale through the appropriate SAFE Chart and HAZOP reviews. For this purpose, a minimum of four (4) weeks notice shall be given to the Department for arrangements to be made for the participation of its representatives at those review meetings with all relevant P&ID’s made available for appropriate review ahead of time.
