Design and Construction Standard                                                                                                                            
During the design, construction, installation, commissioning of a facility, all necessary 
measures and mitigations shall be applied to reduce the risk associated with storage, 
transport, transfer, usage, etc. to as low as reasonably practicable (ALARP). The storage 
tanks, fittings, pumps, manifolds, meters, hoses, valves, and other equipment and

applicable codes and standards. The installation and commissioning of the system shall 
only be undertaken by competent persons and companies, in accordance with the 
manufacturer's instructions and best practices. Written standard procedures shall be 
drawn up and used for installation and/or commissioning. Further conditions governing 
the establishment of a Gas Storage and Utilisation Facility are as follows:   
i. 
Participation of DPR representatives in the project and mandatory witnessing of 
milestone construction activities such as the tank burial, pressure/leak tests and 
tank calibrations.  
ii. 
All critical equipment and piping shall be commissioned after installation in 
accordance with manufacturer’s instructions. Integrity tests and other applicable 
tests shall be conducted companies with relevant OGISP permits and witnessed 
by the Department.   
3.2 
Facility Layout & Site Selection  
3.2.1 
Site Selection Criteria 
1. Any site chosen for the facility shall be sufficiently spacious to allow it to be designed 
to minimize the risks from LNG, CNG or LPG as applicable to any structure close to the 
facility and persons likely to be at or near the facility.
