GUIDELINES REGARDING THE ACTIVITIES REGULATIONS
(Updated 20 December 2012)
The scope of the regulations is limited in comparison with the scope of the Framework Regulations, so that they only apply to offshore petroleum activities.
The provision in the second subsection makes individual requirements in these regulations applicable also for facilities and equipment for conduct of manned underwater operations from vessels. For practical reasons, a choice has been made to have a general section on this, rather than repeating it in the individual provisions.
Re Section 4
Coordinating working environment committees for fields, and joint, local
working environment committees for mobile facilities
The purpose of joint working environment committees is to ensure coordination of the individual enterprises’ safety and environment work and to give all employees a genuine opportunity of taking part in and influencing the safety and environment work at their own workplace, regardless of their employment relationship. Reference is made to Section 7-2 of the Working Environment Act and provisions on safety delegates in Regulations 6 December 2011 relating to organisation, management and participation (in Norwegian only). These regulations also apply directly to the petroleum activities, with the specifications and limitations given in the regulations.
The duty to establish joint working environment committees does not reduce the duty of the individual employer to establish a working environment committee at its own enterprise, cf. Section 34 of the Framework Regulations. The joint working environment committee will be superior to the working environment committees of the individual enterprises in matters related to the jurisdiction of the joint working environment committee.
The term "field" is continued in the new regulations, inter alia to ensure delimitation of the areas that naturally form an entity for such co-ordination.
Coordinating working environment committees for fields as mentioned in the first subsection, should be limited organisationally to ensure representation of all main activity areas, familiarity with the local conditions at the workplace and proximity to the work of the committee. If agreement cannot be reached among the operator, the contractors in the various main activity areas and the safety delegates as to establishing a coordinating working environment committee that comprises more than one field, cf. the requirement regarding general agreement as mentioned in the first subsection, one of the parties can submit the issue to the Petroleum Safety Authority Norway; which, after having considered all aspects of the matter, can decide if such a working environment committee is to be established.
The coordinating working environment committee should set up subcommittees for the individual facilities when the committee encompasses several facilities, cf. Regulations 6 December 2011 relating to organisation, management and participation (in Norwegian only). These regulations also apply directly to the petroleum activities, with the specifications and limitations given in the regulations.
The main activity areas mentioned in the second section, include drilling, well service, catering, construction, maintenance and production. What is to be considered as main activity areas, will depend on the actual activity on the various facilities.
In order to fulfil the requirement for participation as mentioned in the second subsection, the representatives should come from the principal undertaking and from the largest contractors in the various main activity areas. The employees' representatives should be elected by and among the safety delegates and main safety delegates for the various main activity areas. Two or more trade unions that together organise the majority of the employees in a main activity area can agree that the election will take place as a proportionate representation election or that these trade unions will appoint the employees' representatives for the area, cf. Regulations 6 December 2011 relating to organisation, management and participation (in Norwegian only). These regulations also apply directly to the petroleum activities, with the specifications and limitations given in the regulations. The coordinating working environment committee for the field should have at least one employee representative from each manned facility on the field. The operator's representative on a mobile facility can have status either as an observer or as a representative with voting rights. On the joint, local working environment committee on mobile facilities, a representative of the operator can represent the employer side for contractors that have been hired by the operator.
Coordination as mentioned in the last subsection, means coordination of safety and environment-related matters that are of significance for both mobile and permanently placed facilities on the field.
Reference is made to Section 3-3 of the Working Environment Act as regards occupational health services. The new Working Environment Act does not have the same requirements related to safety personnel as earlier versions. However, there remains a need for safety personnel in the offshore petroleum activities, and these are defined as part of the occupational health service. The occupational health service shall be approved by the Norwegian Labour Inspection Authority and shall have a free and independent position in working environment matters, cf. Section 3-3, first and third subsections of the Working Environment Act.
As far as the employers use of occupational health service is concerned, reference is, inter alia, also made to provisions on occupational health service in Regulations 6 December 2011 relating to administrative schemes (in Norwegian only) and Regulations 6 December 2011 relating to organisation, management and participation (in Norwegian only). These regulations also apply directly to the petroleum activities, with the specifications and limitations given in the regulations.
In order to fulfil the requirement for cooperation as mentioned in the second subsection, the operator or the party responsible for the operation of a facility, shall enter into agreements with the principal undertaking and the employers of the contractor employees regarding distribution of the working environment tasks carried out by the occupational health service on the facility.
Long-term effects of working environment factors as mentioned in the first subsection, include long-term effects of hazardous noise.
For requirements related to health examinations as mentioned in the third subsection, reference is made to Section 3-1, second subsection, litera g and Section 10-11, seventh subsection of the Working Environment Act.

Maintenance effectiveness as mentioned in the first subsection, means the ratio between the requirements stipulated for performance and technical condition and the actual results.
The standards NS-EN ISO 14224 and NS-EN ISO 20815, Appendix E, should be used when registering data as mentioned in the first subsection, including failure data and maintenance data.
Re Section 50
Special requirements for technical condition monitoring of structures, maritime
systems and pipeline systems
To fulfil the requirement relating to technical condition monitoring as mentioned in the first subsection, the NORSOK N-005 standard should be used in the area of health, working environment and safety. Floating facilities which shall be inspected and maintained at sea without regular dry-docking, should fulfil DNV OSS-102, Chapter 2, Part 3 H100.
The examinations as mentioned in the fourth subsection, should particularly be carried out with a view towards projected new facilities and use of facilities beyond their original planned lifetime in mind.
Fault modes as mentioned in the fifth subsection, mean both external and internal failure modes.
When finding fault modes as mentioned in the fifth subsection, the DNV RP F-101 guideline should be used if the fault mode is a result of the corrosion failure mechanism.
Re Section 51
Specific requirements for testing of blow out preventer and other pressure
To fulfil the requirement relating to testing, complete overhaul and recertification so that the equipment can fulfil its intended functions, the NORSOK D-010 standard, Chapters 188.8.131.52 and 184.108.40.206 as well as tables 15.4, 15.14, 15.19, 15.21, 15.32, 15.37, 15.38 and 15.47 and Appendix A, Table A.1, as well as DNV RP-E101 should be used. See Section 47 as regards this type of equipment in well interventions and overhaul of subsea wells.
Complete overhaul and recertification as mentioned in the second subsection, may be carried out continuously and in a manner which ensures that single components and the whole unit will be overhauled in a rolling five year period.
The operator shall monitor the external environment as mentioned in Section 48 of the Framework Regulations. This chapter contains complementary provisions on how to implement the monitoring.
The baseline surveys and environmental impact assessments will, together with an overview of discharges, form the basis for planning and implementation of environmental surveys.
The cooperation requirement as mentioned in the first subsection, entails that several operators cooperate so that the monitoring activities are managed in relation to regional risk, the overall content is emphasised and provisions are made for using the best available technology (BAT).
The requirement relating to cooperation in defined regions as mentioned in the first subsection, entails that there shall be agreements between operators that have partly or completely identical areas of impact for pollution from their own activities. The regions may be identical to the geographic scope of the cooperation agreements. Regions for environmental monitoring of operational discharges are described in the Guidelines for environmental monitoring of the petroleum activities on the Norwegian continental shelf (in Norwegian only).
For monitoring and control relating to proper implementation as regards health and safety, see Section 31.
It is vital that the monitoring is conducted in accordance with a defined framework to ensure comparable results between years, and between different regions. The requirements relating to analysis shall also be seen in connection with the international reporting requirements.
Environmental monitoring of the Norwegian continental shelf includes both monitoring of benthic habitats (sediments, soft and hard seabed fauna) and monitoring of the water column. The purpose of the environmental monitoring offshore is to achieve:
– an overview and control of pollution from the offshore activities, including environmental impacts
– an overview of the general condition and development around the individual facilities and in the regions (trends).
The results from the monitoring will, among other things, be used for:
– evaluation of the risk for environmental damage and ecological effects
– verification of models for calculating environmental risk as a function of the existing and expected discharges from the offshore activities
– verification of laboratory research.
It may also be relevant to monitor areas in the beach zone and onshore if these areas are affected by the offshore activity.
The Climate and Pollution Agency (Klif) can, as for the other operator activities, audit the environmental monitoring. This applies to all stages of the activities, from planning of the surveys through to the various operators’ internal use of the results.
Guidelines for the environmental monitoring of the petroleum activities on the Norwegian continental shelf (in Norwegian only) will provide the operators with a template for a standardised way of carrying out the surveys, thus making it possible to compare results from year to year and between various regions. The guidelines cover the most important surveys that all operators shall carry out, and the operators themselves shall decide whether there is need for additional or other surveys on the individual field or in the region. Any deviations from the standard station grid that have been used in previous surveys or given in the guidelines, shall be justified in the programmes for the environmental surveys.
The monitoring results will provide factual data to be used as a basis for decisions on necessary actions to be taken offshore. The results will also be used for calculating national environmental indicators, and will be reported in accordance with international treaties, including OSPAR.
In order to obtain an optimum description of the conditions around the individual facilities and in the region, it is important that the monitoring programmes are designed in light of the existing discharge situation. This means that the operators in the planning stage shall consider and include relevant pollution components in the monitoring programme, as necessary, based on what is discharged on the individual field and in the region. Such an evaluation requires that the monitoring, discharge reporting and defined challenges from the Environmental Impact Assessments be seen as a whole.
The scope of baseline surveys as mentioned in the first subsection, may be adjusted to the need for obtaining new knowledge.
The scope of the surveys as mentioned in the first subsection, litera b, depends inter alia on which particularly vulnerable environmental resources (species and habitats) that may be expected in the area. Particularly vulnerable environmental resources may include coral reefs, spawning grounds, marine mammals, birds and beaches.
As a whole, the monitoring of the benthic habitats shall contribute to explaining whether a station or a larger area around the individual facility or in a region is affected by discharges from the activities. The results from the environmental monitoring shall be such that they can be used to check the conclusions of the impact assessment (IA) for the individual field and for the region. The relation between IA, actual discharges and environmental monitoring shall be emphasised.
A normal frequency for environmental monitoring is every three years. The guidelines may allow for a lower frequency, based on pollution loads, history and regional knowledge.
Since 1997, Norway has used the terms “reference stations” and “regional stations” in connection with monitoring of the seabed on the Norwegian continental shelf. Both types of stations normally cover the background level of selected components in the area, and the reference stations can, in given instances, function as regional stations and vice versa. Reference stations and regional stations in one and the same region are used to estimate background levels in the regions.
The term reference stations is now discontinued, and all non-field-specific stations are called regional stations in the new Guidelines for environmental monitoring of the petroleum activities on the Norwegian continental shelf (in Norwegian only).
There are currently few internationally accepted standardised methods for monitoring of biological effects in the water column. A number of methods are, however, under development,and many have been tested in the field. This primarily applies to various biomarkers which are being used more and more for monitoring impact and, gradually, for monitoring condition. Still, measurement of concentration levels in selected organisms will see further use in the environmental monitoring around petroleum installations on the Norwegian continental shelf. The operators shall participate actively in the testing and development of suitable methods for detecting pollution and environmental effects in the water column. The Climate and Pollution Agency shall be consulted on significant items during the process. As the methods regarding detection of the impact at this stage are still under development and being tested, the guidelines will be regularly revised.
Remote measurement means a system which, regardless of visibility, light and weather conditions, can detect and map the position, area, quantity and properties of acute pollution. Such a system may consist of sensors and equipment deployed in satellites, airplanes and helicopters, or on facilities and vessels with associated services and procedures.
The purpose of the remote measurement is to ensure that the information concerning the pollution is sufficient, so that the correct actions are taken in order to stop, limit and map the pollution.
The remote measuring system can consist of
a) procedures for notification of observations made by personnel on facilities, vessels and aircraft,
b) competence for interpretation of monitoring data from the various available sensors,
c) modelling tools to predict transport and spread of acute pollution,
d) competence for visually quantifying oil and chemicals with the aid of area measurement and colour thickness maps for the relevant types of oil and chemicals,
e) meteorological services that are necessary in order to support the remote measurement,
f) systems for detection and mapping of pollution in the recipients.
In order for the remote measuring system to detect acute pollution of significance, the area surrounding the facility should regularly be subjected to remote measurements. A decision should be made as to the need for continuous remote measuring. A plan for the remote measuring, based on a risk analysis focusing on environmental aspects, should be in place, cf. Section 17 of the Management Regulations.
Follow-up surveys mean chemical and biological surveys both during and after acute pollution. It should be possible to utilise the results of such surveys both during the combat phase with regard to evaluation of relevant measures for optimal combating of the pollution, and in the restoration phase with regard to identification of resources that have been harmed. Such surveys may require special instrumentation and technical measuring equipment, particularly in the event of underwater discharges for surveys in the water column.
The Climate and Pollution Agency's Guidelines for environmental surveys following acute pollution (TA-2995 2012) provide a framework for the contents of such surveys.
Characterisation as mentioned in the first subsection, means collection of chemical and physical survey and analysis data as a basis for dimensioning the emergency preparedness for acute pollution. Such a basis can, in addition to weathering properties and fate in a marine environment, be oil budgets, colour density properties, transport and spread or efficiency of relevant emergency response material, cf. Section 42 of the Facilities Regulations.
Before starting exploration activities, there should at least be a theoretical evaluation of the pollution characteristics as a basis for environment-related risk and emergency preparedness analyses, cf. Section 17 of the Management Regulations.
If the transport of oil in pipelines entails blends that have altered characteristics that are of significance to the environment and emergency preparedness, such blends should be characterised.
A demand analysis should be carried out with regard to small-scale or meso-scale laboratory testing for mapping the oil's weathering properties and fate in a marine environment. The reason for selecting the method for carrying out dispersion should be stated, and the chosen methodology should enable comparison of the results of analyses within the same region.
The requirement relating to cleaning as mentioned in the first subsection, applies to all discharges, but not to displacement water where low oil content and location of the outlet make cleaning impractical.
Oil content as mentioned in the third subsection, means content of dispersed oil in undiluted water.
In addition to the oil content being as low as possible as mentioned in the third subsection, the operator should consider the possibility of reducing the total discharged water volume through, for example, methods such as water shut-off, downhole separation and injection. When technology for cleaning other than dispersed oil becomes available, the Climate and Pollution Agency may set requirements relating to such cleaning.
If oil-contaminated water is injected, cleaning of the water will not normally be required. Information on case processing times can be obtained from the Climate and Pollution Agency upon request.
Polluting emissions to air on the Norwegian shelf come under the scope of the Pollution Control Act (in Norwegian only). With regard to energy-producing plants offshore (existing and new plants with a supplied total nominal thermal output exceeding 50 MW), the EU council directive 96/61/EEC on integrated prevention and limitation of pollution (the IPPC directive) also applies. Pursuant to the EEA agreement, the directive applies to Norway and has been implemented in Norwegian legislation. The directive sets requirements for the pollution control authorities' follow-up of the enterprises and the duties of these enterprises with respect to the environment. Norway's obligations under the directive will be fulfilled by application of the Pollution Control Act (in Norwegian only). Follow-up of the directive implies the stipulation of new requirements for emissions to air from energy-producing plants offshore.
The Pollution Control Act (in Norwegian only) and the IPPC directive require that the best available techniques (BAT) be used when stipulating emission requirements to reflect what can be achieved by using BAT, while not specifying the actual techniques to be used. To help the authorities decide which techniques can be considered BAT, the EU is preparing instructive BAT reference documents, both for individual industries and across industries. These documents show which techniques can be generally considered to be consistent with the IPPC directive’s requirements relating to BAT. Thus, the BREF documents cannot be said to specify BAT requirements as such, but shall be regarded as guidelines for BAT evaluations. The energy-producing plants offshore are included in the BREF for large combustion plants (LCP-BREF). When stipulating what shall be considered BAT in the individual case, the pollution authorities will emphasise available relevant BREFs, the installation’s technical characteristics, its geographical location and the local environmental conditions.
New fields and new development projects shall be operated in accordance with the directive from the date when the activities start (Article 4).
Choice of development solution may be of great importance to the technical and economic consequences by limiting the emissions to air. There may therefore be a mutual connection between the terms set in the emission permit to limit emissions, and the choice of development concept. Therefore, in the event of new developments and upgrading of existing ones, the operator should inform the Climate and Pollution Agency about its BAT evaluations early in the development process, i.e. in ample time prior to making a choice and deciding on development solutions, and prior to entering into binding contracts. This applies regardless of whether this development is subject to the requirement for carrying out impact assessments. The BAT evaluations should also be included in the impact assessment and in the application for emission permit pursuant to the Pollution Control Act (in Norwegian only). In the application, the operator shall demonstrate and substantiate that the chosen solutions can be considered BAT.
According to Section 11 of the Pollution Control Act (in Norwegian only), the company shall apply for emission of NOx and CO2. It follows from Section 11, second subsection of the Pollution Control Act (in Norwegian only) that “a party subject to a quota obligation pursuant to Section 4 of the Climate Quota Act (in Norwegian only), shall, upon application, be granted permission for emissions of greenhouse gases subject to quota obligations if said party can prove that he is able to monitor and report the emissions in a satisfactory manner.”
All chemicals used in the petroleum sector, are comprised by REACH.
Norwegian Accreditation (NA) is the Norwegian agency for the accreditation of technical matters, including GLP as mentioned in the first subsection.
A summary of different types of chemicals that require ecotoxicological documentation in the form of an HOCNF, as mentioned in the second subsection, litera a, is shown in the table below. The operator should carry out an internal environmental evaluation of types of chemicals which do not require an HOCNF. Guidelines for the completing HOCNF are given in "Supplementary guidance for the completing of harmonised offshore notification format (HOCNF) for Norwegian sector”.

Chemicals in firewater systems
*consumption means the initial charging of the system, replacement and all other use of the chemical.
To complete the HOCNF, the OSPAR Guidelines for Completing the Harmonized Offshore Chemical Notification Format should be used.
Re No 1 Biodegradability
When evaluating the properties of the degradation products for substances with moderate degradation (BOD28 between 20 and 60%), the results from testing of inherent biodegradability may be used together with other available information regarding the substances. The evaluations should be documented.
Re No 2 Bioaccumulation
The potential for bioaccumulation is given as the partition coefficient octanol/water, Log Pow. Log Pow from the OECD 117 method shall be stated as the highest value if the results show several values, and all peaks with an area exceeding 5% are counted in the chromatogram . Professional evaluations of bioaccumulation potential and estimate values for Log Pow should be stated in the HOCNF comment field.

The processing of permits as mentioned in this section, follows from Chapter 36 of the Pollution Regulations (in Norwegian only). These regulations include provisions relating to the case processing and the required contents of an application. Information on case processing times can be obtained from the Climate and Pollution Agency upon request.
What is covered by the requirement for a permit in the first subsection:
A permit pursuant to Chapter 3 of the Pollution Control Act (in Norwegian only) shall be obtained in connection with the petroleum activities on the Norwegian continental shelf. This applies to activities in connection with drilling and well operations, production, emptying of pipelines, and other activities entailing the use and discharge of chemicals. The basis for permits as mentioned in the first subsection, is the results from testing, evaluation and categorisation of chemicals as mentioned in Sections 62, 63 and 64.
Chemicals in firewater systems are not subject to the requirement for obtaining a permit in the Pollution Control Act (in Norwegian only), see Section 4, first subsection of the Pollution Control Act (in Norwegian only), cf. Section 7, first subsection cf. Chapter 3. This is covered by the safety rules of the Petroleum Act.
Ordinary pollution from living quarters, offices, etc., including sanitary drainage and chemicals for addition to and cleaning of drinking water systems, are permitted pursuant to Section 8, first subsection, No. 2 of the Pollution Control Act (in Norwegian only), and is therefore not subject to the requirement for obtaining a permit. The Product Control Act (in Norwegian only) and its regulations apply to all chemicals used. This means that the substitution requirement also applies.
In activities that entail use and/or discharge of chemicals in amounts which the operator considers to be very small and not covered by applicable permits, Klif can be contacted to clarify the need for a special permit.
Conditions in the permits:
Specific conditions may be given in the permits for the use and discharge of chemicals, cf. Section 16 of the Pollution Control Act (in Norwegian only). The registration of amounts discharged as described in the Guidelines for reporting from the petroleum activities on the Norwegian continental shelf (in Norwegian only), will be a requirement for discharges to sea and injection.
Even if the use and discharge of chemicals are within the limits set in the discharge permit, the use and discharge shall be reduced to the extent possible. The same applies to the use and discharge of chemicals for which there are no specific use and discharge limits, cf. Section 11 of the Framework Regulations.
Regardless of whether the operator has received permission to use and discharge chemicals, an evaluation shall be made of whether there are other less environmentally harmful alternatives pursuant to Section 3a of the Product Control Act (in Norwegian only).
Categorisation of chemicals, as described in Section 63 of these regulations, will be the basis for the conditions in the permit.
Discharge of substances in the black category will normally not be permitted. If such a permit is given, it will apply to specific chemicals, and a permit will be given for use and discharge of a specific amount of the black category substance. For Klif to grant a permit for use of substances in the black category, the reason for such use is needed, and documentation shall be available. The permit will include a condition regarding these substances having a high priority for substitution.
Upon application, Klif can grant a permit to use and discharge a specific amount of substances in the red category. The permit will include a condition regarding these substances having a high priority for substitution.
For chemicals in the yellow category, specific conditions regarding the use and discharge will not be given, but the permits will state an estimated amount that the operator plans to discharge. The permit will normally include a condition that if a larger amount of substances in yellow category is discharged than stated in the permit, the reason for this shall be stated in the annual discharge report, cf. Section 34, litera c of the Management Regulations.
Normally, Klif will not require information on type and quantity of PLONOR chemicals (chemicals in the green category) in the application. The use and discharge will be covered by the permit. If there are plans to carry out an individual activity (for example drilling or discharges from pipelines) not covered by applicable permits and using only PLONOR chemicals, Klif shall be contacted. In special cases there may be specific conditions given regarding discharges also for PLONOR chemicals. This will depend on the volume discharged, the recipient and the time of the discharge, for example when emptying export pipelines or when the discharges take place in areas with particularly vulnerable resources.
Normally, Klif will not require information on type and amount of chemicals in closed systems if the consumption is less than 3000 kg per year or are lubricants which are not discharged. The use and discharge will be covered by the permit as long as it is in line with relevant regulations pursuant to the Product Control Act (in Norwegian only). Information regarding types and amounts will be required if the use of lubricants is high.
Klif will normally not require information on types and amounts of laboratory chemicals and spray cans in permit applications. The use and discharge will be covered by the permit, if the use and discharge is in line with regulations regarding ozone-reducing substances and other relevant regulations pursuant to the Product Control Act (in Norwegian only).
The ban on discharges of unused chemicals as mentioned in the second subsection, also applies to chemicals on the OSPAR PLONOR list.
Pollution in chemicals as mentioned in the fifth subsection means, for example, heavy metals in weight materials.
When evaluating applications to discharge large amounts of water containing chemicals from pipelines as mentioned in the seventh subsection, Klif will take into account the recommendations from the relevant expert bodies. The conclusions from consulting with independent expert bodies should be included in the application. Large amounts in this case mean volumes greater than 1000 m3 of water.
The operator is not required to apply for a permit to use and discharge emergency preparedness chemicals, but any use and discharge shall be reported as mentioned in Section 34, litera d of the Management Regulations.
The responsible party shall evaluate whether there are less hazardous emergency preparedness chemicals than those in the list of emergency preparedness chemicals, in accordance with Section 3a of the Product Control Act (in Norwegian only).
As regards use of dispersants and beach cleaning agents for combating acute oil pollution, reference is made to Chapter 19 of the Pollution Regulations (in Norwegian only). The Norwegian Coastal Administration is the professional authority in an acute situation if dispersants are not included in the operator’s emergency preparedness plans.
Cuttings as mentioned in the first subsection, means both solid material from the formation and solid material added as part of the drilling fluid or other fluids used in drilling and well activities. Organic drilling fluid means mineral oil-based and synthetic drilling fluid.
Even if the oil or base fluid in synthetic drilling fluid as mentioned in the first subsection, is less than ten grams per kilo of dry substance, the operator should consider additional cleaning or other disposal methods than discharge to sea, for example injection.
Information on case processing times can be obtained from the Climate and Pollution Agency upon request.
Start-up of any flaring as mentioned in the second subsection, should take place in daylight. Information on case processing times can be obtained from the Climate and Pollution Agency upon request.
With regard to measuring, Norwegian Oil and Gas' guidelines for sampling and analysis of produced water can be used.
An overview of which substances the requirement applies to, can be found in Guidelines for reporting from the petroleum activities on Norwegian continental shelf (in Norwegian only). The measurement programme as mentioned in the second subsection, should include a description of the method for manual measurement if an automatic analyser is out of commission. The measurement programme should also cover changes in procedures in cases where unstable operation of the installation is expected or detected.
Organic drilling fluid means mineral oil-based and synthetic drilling fluid. Solids include cuttings, produced sand and other solid materials from the well, such as packing and inert materials.
The requirement relating to measuring also applies to sediments and deposits from process equipment
For handling of waste as mentioned in the second subsection, the Regulations relating to hazardous waste and Chapter 21 of the Pollution Regulations (in Norwegian only), Prohibition against incineration at sea, also apply, as well as other regulations issued in pursuance of Chapter 5 of the Pollution Control Act (in Norwegian only), unless otherwise specifically determined.
Waste oil as mentioned in the third subsection, means used lubricants and similar oils (used in engines, gear boxes, hydraulic systems, transformers, switches etc.) that can no longer be used as originally intended.
The plan for treatment of waste as mentioned in the fourth subsection, should include reduction of waste volume, source separation, reuse, recycling and potential energy recovery.
Information on case processing times can be obtained from the Climate and Pollution Agency upon request.
To fulfil the requirement relating to the strategy as mentioned in the first subsection, the standards ISO 15544 and NS-EN ISO 13702 Chapter 4 should be used for health and safety-related emergency preparedness.
The defined hazard and accident situations as mentioned in the first subsection, mean a representative selection of hazard and accident situations used in the dimensioning of the emergency preparedness.
In order to fulfil the requirement relating to establishing emergency preparedness as mentioned in the first subsection, the NORSOK U-100N standard, Chapters 5.1.5 and 9, should be used for manned underwater operations.
The normal case processing time pursuant to the second subsection, second sentence, is 14 weeks, so that the Climate and Pollution Agency can evaluate whether there are special circumstances making it necessary to set further requirements relating to emergency preparedness.
Special circumstances as mentioned in the third subsection, can be activities where the environmental damage could be considerable, but where the probability of hazard and accident situations which can result in pollution is so low that the acceptance criteria for environmental risk have been met. Another example can be activities where the knowledge basis is deficient.
Contractual cooperation as mentioned in the first subsection, means, for example, entering into agreements relating to common emergency preparedness plans or agreements to use the emergency preparedness resources of others to ensure optimal emergency response in major acute incidents within an area or region.
