Introduction
This Technical Specification deals with the design, construction, commissioning, operation, maintenance and
abandonment of a distribution network, all in order to provide an efficient gas distribution network for the safe
and secure distribution of gas.
It is written in accordance with European Directive 2003/55/EC of 26 June 2003, concerning common rules for
the internal market in natural gas.
The provisions refer to a general organisational scheme in which:
ƒ safety,
ƒ security,
ƒ reliability, and
ƒ efficiency,
of gas distribution activity are highlighted.
This Technical Specification could be an appropriate tool supporting a GDSO in the implementation of a
management system, for example in conjunction with the ISO certification procedure, which needs to be
translated into specialized processes; it could also be used in case of assessment or certification by a third
party.
The use of this Technical Specification is first targeted at all technical operations and processes performed by
a GDSO including those activities carried out by outsourced contractors.
This Technical Specification also deals with the matter of the required competences for technical people
involved in gas distribution activities. In this context, competences should not be confused with "qualification".
The structure of this Technical Specification is based on the documents EN ISO 9001, Quality management
system – Requirements (ISO 9001:2000) and EN ISO 14001, Environmental management systems –
Requirements with guidance for use (ISO 14001:2004) and the technical contents are mainly taken from EN
12007 (all parts), Gas supply systems-Pipelines for maximum operating pressure up to and including 16 bar.
In addition and regarding environmental requirements, the Sector Forum Gas Infrastructure guide should be
taken into account.
Further important reference has been the document written by Study Group SG4.2 of IGU/WOC4 entitled
"Frame of reference regarding Pipeline Integrity Management System", and parts of the internal Procedures
written by distribution Companies.

1 Scope
The field of application of this Technical Specification is the new and existing gas grid starting at the boundary
of the delivery station on the premises of the GDSO up to the point of delivery of the customers that can be at
a means of isolation (e.g. at the outlet of a LPG storage vessel or at the meter outlet connection) typically
nominated by the GDSO and may be defined in national regulations or standards.
For existing installations this Technical Specification does not apply to design, construction, testing and
commissioning.
The main objectives of this Technical Specification can be summarized by the following:
Provide guidance about the minimum necessary requirements to be included in a management system
related to safety, security, reliability and efficiency of technical activities (design, construction, testing and
commissioning/decommissioning, operation and maintenance).
Demonstrate that the competencies required in the activities mentioned above concretely find their
expression in practice on the plants/installations of the gas distribution networks (e.g. for operations in
distribution: odourisation, emergency service, cathodic protection, leak survey, maintenance activities on
pressure reduction plants, mains and service lines).

This Technical Specification is intended for use by a GDSO who has a basic appreciation of quality,
environmental, health and safety (H + S) management and distribution network maintenance and integrity.
The Management System introduced in this Technical Specification refers to gas distribution networks as
defined in the scope and introduction.
It is at the GDSO discretion to include other objects and structures in their own management system.
This Technical Specification is a general framework that applies to all activities of a GDSO including safety
aspects of distribution networks management (i.e. public safety, pipeline monitoring, etc.).

CEN/TS 15399:2007 (E)
If there are preferences over either topics included or the structure of this Technical Specification then, it is at
the discretion GDSO to make necessary adjustments according to their individual needs.
4 Management policy, objectives and targets
The GDSO is responsible for the adoption of a policy with respect to the pipeline design, construction,
commissioning, operation, maintenance and abandonment.
The objective of this policy is to ensure that the system distributes the gas safely and economically while
minimizing service interruptions.
The GDSO should establish and maintain in writing environmental and safety objectives and targets.
In order to meet the above policy objective all necessary precautions and provisions shall be incorporated into
the management system to:
ensure safe operation of the distribution network;
monitor its condition;
ensure maintenance safely and effectively;
deal effectively and responsibly with incidents and emergencies;
develop and maintain all required competencies.
5 Management planning
The management planning shall include objectives by establishing performance measurement indicators and
monitoring the implementation of Environmental and Safety Policy on a regular basis, coming to a
Performance Measurement framework to demonstrate effective safety and environmental performance
according to:
incidents and emergencies that may occur;
severity of consequences;
operations control (i.e. emissions to air, patrolling).
6 Legal and other requirements
The GDSO shall establish and maintain a procedure in writing, to identify and have access to legal and other
requirements.
7 Implementation of a Management System
For implementing a Management System the methodology explained in the EN ISO 9001, Introduction can be
used as a guideline.
A well established methodology to analyse the whole activity of an industrial operator consists of the adoption
of a process approach, methodology promoted in particular by the EN ISO 9001 standard.
Practically, this means to single out the main activities that characterize the operator business.
An activity using resources, and managed in order to enable the transformation of inputs into outputs, can be
considered as a process.
7
---------------------- Page: 9 ----------------------
SIST-TS CEN/TS 15399:2008
CEN/TS 15399:2007 (E)
When used within a management system, such an approach emphasises the importance of:
a) understanding and meeting requirements,
b) need to consider processes in terms of added value,
c) obtaining results of process performance and effectiveness, and
d) continual improvement of processes based on objective measurements.
NOTE In addition, the methodology known as "Plan-Do-Check-Act" (PDCA), can be applied to all processes. PDCA
can be briefly described as follows:
PLAN: Establish the objectives and processes necessary to deliver results in accordance with customer requirements and
the organisation's policies.
DO: Implement the processes.
CHECK: Monitor and measure processes and product against policies, objectives and requirements for the product and
report the results.
ACT: Take actions to continually improve process performance.
Roles, responsibility and authorities shall be defined, documented and communicated in order to facilitate
effective environmental and safety management.
Management shall provide resources essential to the implementation and control of the environmental and
safety management system. Resources include human resources and specialized skills, technology and
financial resources.
The organisation’s top management shall appoint (a) specific management representative(s) who, irrespective
of other responsibilities, shall have defined roles, responsibilities and authority for:
ensuring environmental and safety management system requirements are established, implemented and
maintained in accordance with this Technical Specification;
reporting on the performance of the environmental and safety management system to top management
for review and as a basis for improvement of the environmental and safety management system.
8 Training, awareness and competence
On the basis of a thorough analysis of the working processes, the GDSO shall determine the necessary
amount of economic and human resources needed to carry out all the activities.
The GDSO must also assure that trained, aware and competent human resources are involved in the
execution of each working activity.
In particular the GDSO must take care that people involved in activities with health risks are suitable for the
task, adequately trained and aware of all the risks involved in the activities.
To demonstrate the competence of their personnel the GDSO must:
a) identify the competences and the skills necessary to carry out each working activity;
b) set up general and/or specific training programmes;
c) keep records of the professional training curriculum of each employee, with the indication of all the
courses attended.
It is required also that all personnel whose work may create a significant impact upon the environment have
received appropriate training.
It shall establish and maintain procedures to make its employees or members at each relevant function and
level aware of:
importance of conformance with the environmental and safety policy and procedures and with the
8

SIST-TS CEN/TS 15399:2008
CEN/TS 15399:2007 (E)
requirements of the environmental and safety management system;
significant environmental and safety impacts, actual or potential, of their work activities and the benefits of
improved personal performance;
their roles and responsibilities in achieving conformance with the environmental and safety policy and
procedures and with the requirements of the management system, including emergency preparedness
and response requirements;
potential consequences of departure from specified operating procedures.
Personnel performing the tasks which can cause significant environmental and safety impacts shall be
competent on the basis of appropriate education, training and/or experience.
The competences of the persons involved in the design, construction, commissioning, operation, maintenance
and abandonment of a gas distribution network, or parts of it, shall be in accordance with the characteristics of
the gas distribution network they are working on. These characteristics include, but are not limited to the
following:
a) family of gas;
b) local conditions;
c) design or operating pressure;
d) materials used in the system;
e) jointing techniques;
f) emergency procedures.
All personnel involved in technical activities (employees of the GDSO, but also of the subcontractors) should
be selected, trained and developed to carry out their respective technical duties in a safe and efficient manner.
In addition, the operator may define and set up procedures to ensure that its employees working at each level
are aware of:
importance of conformance to the GDSO policy, and to the requirements of the management system;
their roles and responsibilities in achieving conformance to the GDSO policy, the procedures and the
requirements of the management system.
The GDSO should undertake actions in order to maintain high technical knowledge and to introduce them
when necessary to the technical development.
Examples concerning the development of technology are:
a) communication;
b) cathodic Protection;
c) inspection methods;
d) pressure regulation;
e) gas measurement and odorisation;
f) pipe coating;

9 Communication
Management shall ensure that appropriate communication processes are established within the organisation
and that communication takes place regarding the effectiveness of the management system.
With regard to its environmental and safety aspects, the GDSO shall establish and maintain procedures for:
internal communication between the various levels and functions of the organisation;
receiving, documenting and responding to relevant communication from external interested parties.
The GDSO shall consider processes for external communication on its significant aspects and record its
decision.
Environmental and safety instructions should be controlled to ensure that they are accurate, relevant and
readily available to enable safe operations.
Procedures for ensuring that this information should be communicated to and from employees and other
interested parties may be defined.
Information and procedures dealing with the hazards prevention and covering emergencies should be
communicated to all the concerned personnel of the GDSO.
A liaison can be established with appropriate public authorities (fire and police officials).
10 Document control
The document control should additionally consider:
a) activities inside the Company are performed following the established internal procedures and
instructions and technical prescriptions;
b) level of responsibility and the competences are respected in the execution of the work;
c) possibility to keep track of each communication exchange within and outside the Company;
d) constant improvement in the quality of the service provided to the customers through the revision
of procedures and instructions.
Before being circulated, documents should be reviewed and approved by authorised persons. They are
readable, easily identifiable and accessible. Any non-valid or obsolete document should be withdrawn or
appropriately identified as such.
Records should be established and kept to provide evidence of conformity with requirements and to provide
efficient operations. They must remain readable, easy to identify and accessible.
11 Hazard identification
11.1 Environmental and safety aspects
The GDSO shall establish and maintain (a) procedure(s) to identify and assess all potential hazards related to
the environmental and safety aspects of its activities, products or services that it can control and over which it
can be expected to have influence, in order to determine those which have or can have significant impacts on
the environment. The GDSO shall ensure that the aspects related to these significant impacts are considered
in setting its environmental and safety objectives. The GDSO shall keep this information up –to date.
Appropriate controls and systems should be implemented to reduce and manage those hazards. The GDSO
shall implement the necessary control measures, both in routine and non-routine activities. The GDSO should
include assessing the results and the effects of the controls in the operator policy when relevant.
The construction of gas distribution networks should be organised so that the impact on the environment
during construction is reduced to the minimum practicable level. During the laying of mains and services,
special precautions should be taken to minimise any disturbance to adjacent drainage networks and other
10
---------------------- Page: 12 ----------------------
SIST-TS CEN/TS 15399:2008
CEN/TS 15399:2007 (E)
buried installations. Inconvenience to road users caused by construction, maintenance or operation of the
system should be minimized.
During construction all reasonable measures should be taken to avoid damage to trees and other vegetation.
Above ground parts of the gas distribution network such as regulating and measuring stations should be
designed and located in order to reduce environmental impact as far as reasonably practicable.
The gas distribution network, especially the regulating and measuring stations, should be designed to
minimise, as far as is reasonably practicable, the emitted noise level and the effects on neighbours.
All unwanted materials or waste shall be disposed of properly.
11.2 Gathering and analysis of incidents
Each relevant incident to the gas distribution network (pipelines and stations) during operating or maintenance
phases, with reference to the protection of workers (see Directive 89/391/CE), should be the object of an
analysis to identify its causes and define the corrective measures to be implemented. An accident report
should systematically be drawn up.
An accident status review may be carried out periodically to highlight recurrent problems and take any
necessary preventive action.
The GDSO may establish procedures to define the responsibility and the authority for:
handling and investigati
