The purpose of this document is to:
— ensure the health and safety of the public and all site personnel;
— cover environmental issues;
— avoid incidental damage to nearby property; and
— open the gas infrastructure to accommodate renewable gases, including a possible design for hydrogen.
This document specifies common basic principles for the gas infrastructure. Users of this document are expected to be aware that more detailed national standards and/or codes of practice can exist in the CEN member countries.
This document is intended to be applied in association with these national standards and/or codes of practice setting out the above-mentioned basic principles.
In the event of conflicts in terms of more restrictive requirements in national legislation/regulation with the requirements of this document, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts). CEN/TR 13737 (all parts) gives:
— clarification of all legislations/regulations applicable in a member state;
— if appropriate, more restrictive national requirements;
— a national contact point for the latest information.
This document does not apply to:
— off-shore gas compressor stations;
— gas compressor stations for compressed gas filling-stations;

This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association.
There is a complete suite of functional standards prepared by CEN/TC 234 “Gas infrastructure” to cover
all parts of the gas infrastructure from the input of gas into the onshore transmission network up to the
inlet connection of gas appliances, including including !injection, transmission, compression,
pressure control, storage, blending, gas treatment, odorisation, distribution, measuring, and associated
installation pipework, as well as related requirements such as safety, gas quality, sustainability,
environment and emissions. Within the scope of CEN/TC 234, gaseous energy carriers and blends
describe gases which are in the gaseous state when conveyed in the gas pipeline infrastructure such as
hydrogen, hydrogen rich, and methane rich gases, dimethyl ether (DME) and propane and butanes used
for combustion and/or as feedstock, excluding steam and compressed air." In preparing this
document a basic understanding of gas infrastructure by the user has been assumed.
The gas infrastructure is complex and the importance on safety of its construction and use has led to the
development of very detailed codes of practice and operating manuals in the member countries. These
detailed statements embrace recognized standards of gas engineering and the specific requirements
imposed by the legal structures of the member countries.
!Directive (EU) 2024/1788" concerning common rules for the internal market in natural gas and
the related Regulation !(EU) 2024/1789" on conditions for access to the natural gas transmission
networks also aim at technical safety (security) including technical reliability of the European gas
system. These aspects are also in the scope of CEN/TC 234 standardization. In this respect CEN/TC 234
evaluated the indicated EU legislation and amended this document accordingly, where required and
appropriate.
In this edition of EN 12583 environmental aspects relevant to the design, construction and testing,
operation and maintenance, decommissioning and disposal of compressor stations in the scope of this
document are covered in accordance with CEN Guide 4 and CEN/TR 16388.
Directive !(EU) 2018/2001, Articles 3 and 7" are with regard to the calculation of the share of
energy from renewable sources and the contribution of hydrogen originating from renewable sources
in the total fuel mix. In this respect CEN/TC 234 evaluated the indicated EU legislation and amended
this document.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the

4 Safety
The occupier shall have a Safety Management System (SMS) for its gas infrastructure and a Pipeline
Integrity Management System (PIMS) for its gas transmission pipelines. Reference can be made to
!EN 17649".
Safety aspects relating to the specific requirements of gas compressor stations are covered by this
document. For those aspects not covered by this document, relating to the equipment installed,
reference shall be made to the relevant standards in force.
The safety measures shall be based on the prevention of incidents (deterministic approach) or on
probability considerations. These measures take into account the safety and environmental conditions
existing at the time of construction.
5 Asset management and quality assurance
A management system shall be applied to ensure systematic and coordinated activities and practices
through which the organization optimally and sustainably manages its assets and asset systems, their
associated performance, risks and expenditures over their life cycle for the purpose of achieving the
organisational strategic plan.
A quality system should be applied to all the activities in the application of this document.
Reference can be made to EN ISO 9001 and EN ISO 9004.
6 Environmental constraints
6.1 General
Methods for emissions reduction should be evaluated. In combustion systems, primary dry methods to
avoid pollution production shall be preferred.
Energy conserving approaches should also be considered in order to reduce emissions.
Where there is a potential of leakages or spills of polluting fluids, these shall be protected with non-
penetrating, contamination preventing structures, for instance liquid tight floors and spill basins.
Consideration should be given to the requirements of EN ISO 14001 and EN ISO 50001.
Waste materials (e.g. used oil, filters, chemical waste, packing materials, etc.) should be separated in
accordance with local legislation and be disposed of by certified waste disposal companies or
organizations.
6.2 NOx and CO determination
6.2.1 General
Considering the IED (Industrial Emission Directive), the IED BREF (Best available techniques
References) chapter 10 (Conclusions) and the MCP-directive, the NO and, to some extent, CO
x
concentrations in exhaust gases shall be determined either: by Periodic measurements, by a Continuous
Emission Monitoring System (CEMS) or by a Predictive Emission Monitoring System (PEMS).
6.2.2 Periodic measurements
The periodic measurements shall be made in accordance with applicable standard reference methods,
carrying out short measurement campaigns with a temporarily installed certified analyser.
The periodicity can depend on a reference installed thermal power, the installation age and/or the
running hour status.
Under no circumstances should a low running hour unit be started and consequently emit pollutant in
the atmosphere, solely for emission measurement purposes.
During site construction (new site) or stack renewal, EN 15259 should be applied to ensure the proper
measurement point arrangement is achieved with the adequate and safe accessibility.
6.2.3 Continuous Emission Monitoring System (CEMS)
A Continuous Emission Monitoring System (CEMS) is a measuring system permanently installed on site
for continuous measurement and monitoring of emissions in the exhaust gases
