Petroleum and natural gas industries - Arctic operations - Environmental monitoring (ISO 35103:2017)

ISO 35103:2017 gives requirements, specifications and guidelines to ensure that environmental monitoring in the offshore Arctic region is fit for purpose. The Arctic region includes the territory lying to the North of the Arctic Circle (Latitude 66°33′45.8″). This document can be applied to sub-Arctic locations which experience Arctic-like conditions and contain relevant components of a cold-climate ecosystem.
ISO 35103:2017 is applicable to all Arctic oil and gas operations from licence block acquisition through exploration, engineering design, construction, commissioning, operation, decommissioning and restoration. It covers the offshore or maritime environment, including for the purposes of this document, the fully marine and estuarine waters of the Arctic, whether frozen or ice-free. The environment includes all relevant physical, chemical and biological components. Monitoring methods for onshore (terrestrial) environments are not covered in this document, although onshore environments are included where monitoring is required at onshore locations in relation to an offshore development.
ISO 35103:2017 covers both monitoring of environmental aspects for normal, abnormal and emergency conditions, and monitoring of environmental impacts. It includes monitoring in near-field, far-field, transboundary and regional scales, but does not include global environmental monitoring.

Industries du pétrole et du gaz naturel - Opérations en Arctique - Surveillance de l'environnement (ISO 35103:2017)

L'ISO 35103:2017 fournit des exigences, des spécifications et des lignes directrices visant à assurer l'adéquation de la surveillance de l'environnement dans la région maritime arctique. La région arctique comprend le territoire situé au nord du cercle arctique (latitude 66°33′45.8″). Le présent document peut être appliqué aux zones subarctiques dont les conditions sont similaires à celles en Arctique et qui comprennent des éléments caractéristiques d'un écosystème climatique froid.
L'ISO 35103:2017 est applicable à l'ensemble des opérations pétrolières et gazières en Arctique, depuis l'acquisition de droits exclusifs d'exploitation jusqu'à la réhabilitation, en passant par l'exploration, l'étude technique, la construction, la mise en service, l'exploitation, la mise hors service et la restauration. Il couvre l'environnement marin ou maritime, qui inclut dans le cadre du présent document l'ensemble des eaux marines et estuariennes de l'Arctique, qu'elles soient gelées ou non. L'environnement comprend tous les composants physiques, chimiques et biologiques pertinents. Les méthodes de surveillance des environnements côtiers (terrestres) ne sont pas couvertes par le présent document, bien que les environnements côtiers soient pris en compte lorsque la surveillance d'emplacements côtiers est nécessaire dans le cadre d'un développement en mer.
L'ISO 35103:2017 couvre à la fois la surveillance des aspects environnementaux dans des conditions normales, anormales et d'urgence, et la surveillance des impacts environnementaux. Elle inclut la surveillance en champ proche, en champ éloigné et aux échelles transfrontière et régionale, mais pas la surveillance de l'environnement à l'échelle globale.

Industrija za predelavo nafte in zemeljskega plina - Obratovanje v arktičnem okolju - Okoljsko nadzorovanje (ISO 35103:2017)

Standard ISO 35103:2017 določa zahteve in vodila za zagotavljanje, da je okoljsko nadzorovanje, ki se izvaja v priobalni arktični regiji, primerno za svoj namen. Arktična regija zajema območje, ki leži severno od arktičnega kroga (zemljepisna širina 66°33′45,8″). Ta dokument je mogoče uporabiti za subarktične lokacije, na katerih so pogoji podobnimi arktičnim in ki zajemajo ustrezne komponente hladnega klimatskega ekosistema.
Standard ISO 35103:2017 se uporablja za vso obratovanje industrije za predelavo nafte in zemeljskega plina v arktičnem okolju, od pridobivanja licenčnih blokov do raziskovanja, inženirskega projektiranja, gradnje, začetka uporabe, delovanja, prenehanja uporabe in obnovitve. Zajema priobalno ali morsko okolje, vključno za namen tega dokumenta, z vsemi morskimi vodami in vodami v rečnih ustjih Arktike, ne glede na to ali so zamrznjene ali brez ledu. Okolje zajema vse ustrezne fizične, kemijske in biološke komponente. Metode nadzorovanja za kopenska (zemeljska) okolja niso zajete v tem dokumentu, so pa kopenska okolja vključena, kadar je nadzorovanje potrebno na kopenskih lokacijah v povezavi s priobalnim razvojem.
Standard ISO 35103:2017 zajema nadzorovanje okoljskih vidikov za običajne in neobičajne pogoje ter pogoje v sili, pa tudi nadzor okoljskih vplivov. Zajema nadzorovanje v bližnjem območju, daljnem območju, v čezmejnem in regionalnem obsegu, ne zajema pa globalnega okoljskega nadzorovanja.

bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
General
This document has been developed in order to promote internationally agreed approaches to
environmental monitoring of oil and gas operations in Arctic offshore environments. The monitoring
of onshore environments is not included in this document, except where relevant to an offshore
development.
Environmental monitoring
Environmental monitoring includes:
a) monitoring of environmental aspects for normal, abnormal and emergency conditions:
The environmental aspects of an organization under all conditions are determined by its
environmental management system (EMS) procedures and can include:
1) emissions to air;
2) releases to water;
3) releases to land;
4) use of raw materials and natural resources, including physical presence of facilities;
5) use of energy;
6) energy emitted, including heat, radiation, vibration, noise and light;
7) generation of waste and/or by-products;
8) environmental aspects with beneficial impact;
b) monitoring of environmental impacts:
Environmental impacts can occur at local, regional and global scales, while they can also be direct,
indirect or cumulative.
The relationship between environmental aspects and environmental impacts is one of cause and effect.
Within the scope of this document, the environment includes all relevant physical, chemical and
biological components of the sea, atmosphere and land, where the latter is potentially impacted by an
offshore development. When an organization determines the scope of its environmental impact, the
need to protect the following attributes is considered:
— human beings and cultural heritage;
— fauna and flora;
— soil, water, air and climate;
— material assets (such as existing pipelines and cables, shipping routes, seabed resources and
resource extraction facilities).
There are no existing internationally agreed standards for environmental monitoring; neither are there
such standards for marine environmental monitoring although there is a considerable body of guidance
documents.
This document presents sufficient information to guide organizations towards relevant monitoring
methods for use in the Arctic.

SIST EN ISO 35103:2019
ISO 35103:2017(E)

The special conditions of the Arctic will require organizations to modify their monitoring methods to
suit the conditions encountered.
General marine monitoring methods can be adapted by the oil and gas sector to meet the needs of its
Arctic maritime locations, its development phases, facility types and operations, their environmental
aspects and their impacts upon the marine environment.
Relationship of this document to ISO 14001, ISO 9001 and other standards
The organizations that have implemented ISO 14001 or ISO 9001 already apply the elements of
monitoring, measurement, analysis and improvement to their (environmental) monitoring processes.
Additional standards that apply to environmental monitoring include laboratory standards, specific
guides on sediment, water and air quality monitoring, and recommended practices for species
identification; the use of agreed statistical methods is essential.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

Introduction
General
This document has been developed in order to promote internationally agreed approaches to
environmental monitoring of oil and gas operations in Arctic offshore environments. The monitoring
of onshore environments is not included in this document, except where relevant to an offshore
development.
Environmental monitoring
Environmental monitoring includes:
a) monitoring of environmental aspects for normal, abnormal and emergency conditions:
The environmental aspects of an organization under all conditions are determined by its
environmental management system (EMS) procedures and can include:
1) emissions to air;
2) releases to water;
3) releases to land;
4) use of raw materials and natural resources, including physical presence of facilities;
5) use of energy;
6) energy emitted, including heat, radiation, vibration, noise and light;
7) generation of waste and/or by-products;
8) environmental aspects with beneficial impact;
b) monitoring of environmental impacts:
Environmental impacts can occur at local, regional and global scales, while they can also be direct,
indirect or cumulative.
The relationship between environmental aspects and environmental impacts is one of cause and effect.
Within the scope of this document, the environment includes all relevant physical, chemical and
biological components of the sea, atmosphere and land, where the latter is potentially impacted by an
offshore development. When an organization determines the scope of its environmental impact, the
need to protect the following attributes is considered:
— human beings and cultural heritage;
— fauna and flora;
— soil, water, air and climate;
— material assets (such as existing pipelines and cables, shipping routes, seabed resources and
resource extraction facilities).
There are no existing internationally agreed standards for environmental monitoring; neither are there
such standards for marine environmental monitoring although there is a considerable body of guidance
documents.
This document presents sufficient information to guide organizations towards relevant monitoring
methods for use in the Arctic.

The special conditions of the Arctic will require organizations to modify their monitoring methods to
suit the conditions encountered.
General marine monitoring methods can be adapted by the oil and gas sector to meet the needs of its
Arctic maritime locations, its development phases, facility types and operations, their environmental
aspects and their impacts upon the marine environment.
Relationship of this document to ISO 14001, ISO 9001 and other standards
The organizations that have implemented ISO 14001 or ISO 9001 already apply the elements of
monitoring, measurement, analysis and improvement to their (environmental) monitoring processes.
Additional standards that apply to environmental monitoring include laboratory standards, specific
guides on sediment, water and air quality monitoring, and recommended practices for species
identification; the use of agreed statistical methods is essential.

Petroleum and natural gas industries — Arctic operations
— Environmental monitoring
1 Scope
This document gives requirements, specifications and guidelines to ensure that environmental
monitoring in the offshore Arctic region is fit for purpose. The Arctic region includes the territory lying
to the North of the Arctic Circle (Latitude 66°33′45.8″). This document can be applied to sub-Arctic
locations which experience Arctic-like conditions and contain relevant components of a cold-climate
ecosystem.
This document is applicable to all Arctic oil and gas operations from licence block acquisition through
exploration, engineering design, construction, commissioning, operation, decommissioning and
restoration. It covers the offshore or maritime environment, including for the purposes of this document,
the fully marine and estuarine waters of the Arctic, whether frozen or ice-free. The environment
includes all relevant physical, chemical and biological components. Monitoring methods for onshore
(terrestrial) environments are not covered in this document, although onshore environments are
included where monitoring is required at onshore locations in relation to an offshore development.
This document covers both monitoring of environmental aspects for normal, abnormal and emergency
conditions, and monitoring of environmental impacts. It includes monitoring in near-field, far-field,
transboundary and regional scales, but does not include global environmental monitoring.
