Guidance on conceptual design, selection and life cycle assurance of products intended to improve integrity of bases of above-ground storage tanks for bulk storage of petroleum, petroleum products or other fuels
Upcoming EI publication
Secondary containment below above-ground storage tanks (ASTs) is an established requirement for bulk storage of petroleum, petroleum products or other fuels in above-ground storage tanks. In Great Britain (GB), most of these storage sites are regulated under the Control of major accident hazards (COMAH) regulations, and secondary containment is specified in COMAH competent authority (CA) Policy on containment of bulk hazardous liquids at COMAH establishments (‘Containment policy’) and its associated guidance COMAH CA policy on containment of bulk hazardous liquids at COMAH establishment: Supporting guidance for secondary and tertiary containment and implementation principles for regulators (‘Containment policy implementation principles’). To a large extent, current requirements arise from the prominent discussion of secondary containment bunds during the investigation following the Buncefield incident and the subsequent practical interpretation of pertinent investigation recommendations.
Nevertheless, the detail and range of below tank secondary containment design and operation, including inspection and testing, have not been well documented. In recognition of the wide range of factors impinging on how to improve integrity of below secondary containment and the significant cost implications of installing or upgrading below tank secondary containment, the Energy Institute (EI) commissioned research examining bund liner conceptual design criteria and methods of appraising performance, particularly pertaining to the permeability of the containment, and its integrity performance over time. The research informed the development of this publication. This publication is the second report in a series of two, and complements the existing EI publication Guidance on the conceptual design, selection and life cycle assurance of liners intended to improve integrity of bunds to above-ground storage tanks for bulk storage of petroleum, petroleum products or other fuels.
Both documents provide a comprehensive Europe-wide review of the design process for environmental protection, below above-ground storage tank (tank) design and installation.
This publication is due to be published shortly.
