|Consent Needed (also see OBM and SBM Use and WBM Use and Discharge for further non-chemical consent requirements):||
There is a requirement for the operator to obtain a permit to use and discharge drilling chemicals. This permit must be in place before commencement of operations.
For discharges of excess cement and other surplus material at end of operations – see the Performance Standards tab.
Marine Licensing Exempt Activities – A list of exemptions to marine licensing has been published and it details activities exempt from marine licensing and which exemptions require the MMO to be notified and which exemptions require MMO approval. This includes ‘cables and pipelines – authorised emergency repair and inspection’ and ‘deposit of marine chemical and marine oil treatment substances’.
|What to Include to Permit Authorisation:||An application for the grant of a permit from BEIS under regulation 4 is made via an electronic drilling operations application. It shall contain:
The regulations allow for the acquisition of further information if that submitted is deemed insufficient or incorrect and for the gathering of evidence to verify any statements made.
Note: The drilling operations application will consist of two elements: the Master Application Template (MAT) and the Subsidiary Application Template (SAT). Completion of the MAT provides access to various SATs:
In addition, as part of ongoing reviews of oil spill contingency arrangements in light of the Macondo well incident, drilling operation applications for exploration, appraisal or development wells must:
Additional changes may be required in the future, when BEIS has reviewed outstanding reports relating to the Macondo incident.
|How to Apply:||
Applications should be made using the following forms: Wells and sidetracks (including new drilling from platforms) – drilling operations application. Workovers, if part of the drilling programme (outside the platform 500m safety zone) – drilling operations application. Alternatively the well intervention operations application can be used for all workovers and well intervention programmes – see Workover.
|Who to Apply to:||
PETS applications must be submitted electronically to BEIS via the UK Oil Portal. Operators will need to be registered with BEIS for access to the Portal. To set up a UK Oil Portal Account, contact the BEIS OED Environmental Management Team at email@example.com. If you have any problems with PETS submission, contact the BEIS OED EMT by email at firstname.lastname@example.org
|When to Apply:||
PETS (term permits) applications must be made at least 28 days before drilling commences. However, if also seeking a direction that an ES is not required, additional time should be allowed for. Well intervention operations applications must be made at least 28 days before workover or completion. Well intervention operations applications may be for annual or term permits (see Workover).
|Requirements of the Regulations:||
Operators will need to assess the risks to the environment, which might arise from their particular chemicals use and discharge. For some chemicals, e.g. those on the OSPAR PLONOR list, assessment will be straightforward. Others will require a formal process of risk assessment, such as can be done using CHARM software. In this process, the predicted environmental concentration (PEC), determined from a knowledge of individual substance or product chemistry and the conditions of use, is compared with the Predicted No-effect Concentration (PNEC) determined from toxicity tests conducted to agreed protocols. This allows more informed assessments of risk to local sensitivities to be made in particular use and/or discharge scenarios. The use of the CHARM model is compulsory for calculating the Hazard Quotient (HQ) but other risk assessment models may be used to calculate the Risk Quotient (RQ) provided comparability with CHARM can be demonstrated.
|Pipe Dopes containing Lead:||OSPAR has now published its overview assessment of the implementation of OSPAR Recommendation 2005/2 on environmental goals for the discharge by the offshore industry of chemicals that are, or contain added substances, listed in the OSPAR List of Chemicals for Priority Action. This refers to the treatment of pipe dopes containing lead. The discharge of pipe dopes containing lead is now prohibited. All future PETS applications to use pipe dopes containing lead should only relate to activities where there is no planned or anticipated “discharge” of the dope, and should accordingly be entered in the application and the EEMS return as Zero Discharge. Text should also be included in chemical risk assessment SAT and/or EIA SAT of the application to confirm the measures that will be taken to justify the zero discharge estimate (detailing how it is being used to ensure zero discharge). Discharges of these pipe dopes are now prohibited, and the Department will be refusing to accept applications that include a proposed discharge of pipe dopes containing lead.Alternative pipe dopes that do not contain lead can continue to be used for applications where there is an anticipated discharge, and should continue to be assessed and entered in the application and the EEMS return using the default 10% discharge estimate.|
|Controls Placed on the Type and Volume of Drilling Chemicals Discharged:||
Conditions of an approved permit will indicate the types and volumes of chemicals that may be discharged into the environment. These conditions must not be exceeded.

|UK National Plan for the phase-out of substances identified as candidates for substitution – in line with OSPAR Recommendation 2006/3:(The full text of the current UK National Plan for phase out can be found on the CEFAS website)||OSPAR Recommendation 2006/3 requires that as soon as is practicable and no later than 1 January 2017, Contracting Parties to OSPAR should have phased out the discharge of offshore chemicals that are, or which contain substances, identified as candidates for substitution except for those chemicals where despite considerable efforts, it can be demonstrated that this is not feasible due to technical or safety reasons. Demonstration of those reasons should include a description of those efforts. Having considered the requirements of OSPAR Recommendation 2006/3, the UK has decided to base its National Plan for the prioritisation of phase-out on the following criteria:
The UK National Plan also incorporates justification of continued use and/or discharge as an additional element: for those substances where replacement and/or eliminating discharges to the marine environment is not currently feasible, offshore operators or their chemical suppliers will annually be required to:
UK National Plan level criteria and interim target dates are (See the full text of the UK National Plan (PDF document) from the CEFAS website for definitions of persistence, bioaccumulating and toxicity):
EC Regulation 1907/2006 (REACH):REACH deals with the Registration, Evaluation, Authorisation and Restriction of Chemical substances. The aim of REACH is to improve the protection of human health and the environment through the better and earlier identification of the intrinsic properties of chemical substances. At the same time, innovative capability and competitiveness of the EU chemicals industry should be enhanced. The benefits of the REACH system will come gradually as more and more substances are phased into REACH.
The HSE is the UK Competent Authority for REACH and is working closely with Defra plus other Government Departments and Agencies on the policy/enforcement aspects. HSE enforces maritime Health and Safety Regulations which apply to offshore installations.
To ensure a consistent regime, the offshore enforcement of REACH will be carried out by those who are familiar with enforcement requirements in similar circumstances to that required by REACH. Therefore, HSE and BEIS will enforce offshore the aspects of REACH relating to health/safety and environmental protection, using their respective onshore administrative procedures and offshore inspectors to check compliance with the relevant provisions. In this regard, BEIS sits on the REACH Enforcement Liaison Group (established by the HSE) to ensure that a proportionate and consistent method of enforcement is adopted.
From an offshore environmental protection perspective, the OSPAR HMCS and REACH requirements will run in parallel, with the HMCS approach to controlling offshore chemicals being appropriately harmonised with the provisions of the EU Regulation. Accordingly, the UK REACH Enforcement Regulations contain certain provisions from, and makes references to, the OCR, so effectively OCR (and hence the HMCS) will be the mechanism for supporting the application of the environmental protection elements of REACH to offshore installations. It should, however, be noted that BEIS’s regulatory regime for offshore chemicals does not extend to Scottish controlled waters and therefore, in so far as this area is concerned, REACH will be enforced by an authorised body (i.e. SEPA) on behalf of the Scottish Executive. REACH provisions will be phased-in over 11 years.
Appendix 1 of the BEIS (then DECC) Guidance Notes on Reach (Word document) addresses Specific REACH issues pertaining to the offshore sector.A Timetable of REACH Implementation (Word document) is available on the BEIS Website.
|Chemicals:||All chemical use/discharge must be monitored and recorded. Components of oil based mud systems must be listed individually with their appropriate use and discharge (see the Reporting Requirements tab).|
|Routine Monitoring:||Periodic monitoring of the area around installations may be requested to confirm impact hypotheses and to check that the general health of the marine environment in the vicinity of installations remains acceptable. The operator will carry out the monitoring and bear any costs involved.|
|Check Monitoring (Inspections):||The Regulations state – “Government will, as circumstances dictate, conduct check monitoring. It will seek to confirm that routine monitoring is generating accurate returns. The costs of this monitoring will be recovered under the scheme”. Where an inspector considers that any activity in relation to the use or discharge of an offshore chemical involves a serious and imminent risk of pollution, he may give such directions in relation to that activity (including a direction requiring the cessation of that activity), as he considers necessary to avoid or minimise the risk of pollution in question.|
|What to Report:||
Chemical Use and Discharge
Reports should be made on all drilling and well chemicals, as required by BEIS, electronically via the EEMS website. Reports are made on the drilling chemicals and fluids with spreadsheets also available for download on the EEMS website. As well as being used by BEIS to check actual use and discharge of chemicals against the term permit, they will also be used towards compilation of the OSPAR returns, which Contracting Parties are obliged to make. For certain problematic substances, such as those identified for substitution, the Department may require more frequent reporting. A condition in the permit will make this clear if necessary.
Annual Progress Reports on Substitution Chemicals
Previously progress reports on substitution chemicals have only been requested for production chemicals (Production operation permit). This reporting requirement is now extended to term permits. A reporting template can be downloaded here (Excel document). Reporting includes summary of chemicals replaced, summary of chemicals still to be replaced and justification for continued use and/or discharge. This guidance document explains the completion of reporting spreadsheets. Some minor modifications have been made to the Annual Reporting spreadsheets and the Technical Justification Report (TJR) spreadsheet since the 2014 version.
|Who to Report to:||Chemical Use and Discharge Reports need to be made electronically on the EEMS website after each well. BEIS will use EEMS reports to cross check against permit conditions to ensure compliance.
Annual Progress Reports on Substitution Chemicals
Reports need to be submitted to BEIS Environmental Management Team by email to email@example.com
|When to Report:||Chemical Use and Discharge EEMS reports to be submitted 28 days after permit expiry date. Annual progress reports are required to be submitted on or before 28 February of each calendar year.|
|Non Compliance:||The BEIS (then DECC) Permit Condition Non-Compliance Notification Form (Word document) is to be used for reporting any identified non-compliances against Chemical Permit conditions issued under the provisions of the Offshore Chemical Regulations 2002. Examples of these may include, but are not limited to: identified overuse of chemicals or use and/or discharge of chemicals not included on the permit. In addition the form may be used to notify BEIS of any other applicable notifications specifically as required by the chemical permit conditions as appropriate.Variations to chemical permits should be made before exceeding permit limits. Emergency approval of chemical use and/or discharge can be obtained out of normal office hours by contacting the BEIS Duty Officer – ask to be connected to the On-Call Response Office (Offshore Environmental Inspectorate). Guidance on emergency approval can be found in the Guidance Notes of the Legislation tab.If a variation is not in place before the unpermitted use or discharge occurs, a non-compliance notification form should be submitted. It is an offence not to submit a non-compliance report if required.|
|Chemical Spill:||Any accidental spill of chemicals must be reported to BEIS using a PON1 (see Chemical Spills for additional details).|
|Inspections:||At any reasonable time (or in a situation which in his opinion may give rise to a risk of significant pollution to the environment as a result of the use or discharge from an offshore source of an offshore chemical, at any time) the inspector may board any offshore installation to undertake inspections and investigations. The BEIS (then DECC) Environmental Inspectorate Enforcement Policy (PDF document) sets out the general principles that Inspectors shall follow in relation to enforcement, including prosecution.|
|Enforcement and Prohibition Notices:||BEIS, if of the opinion that the OCR 2002 Regulations have been contravened, may issue an enforcement notice. This will specify:
If an enforcement notice is not addressed, BEIS may take action itself and recover reasonable costs back from the operator. If BEIS is of the opinion that the operation of an offshore installation involves an imminent risk of serious pollution as a consequence of any discharge of chemical, BEIS may serve a prohibition notice. This will specify the pollution risk, the steps required to remove it and the time period, and may withdraw a permit wholly or in part until the prohibition notice is withdrawn.
|False or Misleading Information:||BEIS may by notice revoke a permit granted where they are of the opinion that the application for the permit in question contained any information or statement which was false or misleading in a material particular or where the operator in question has been guilty of a breach of any condition attached to the permit.|
|Offences:||A person is guilty of an offence if he:
|Proposals for an Integrated Framework of Environmental Regulation:||The proposals outlined by SEPA will deliver a simpler legislative framework which will enable SEPA to focus greater effort on the environmental problems that matter most. It will provide a more consistent range of enforcement tools so that proportionate and effective action can be taken against those who would damage the environment. The consultation that has been undertaken is built on previous consultations focusing on changes to the structure of environmental protection legislation in order to create a new, integrated framework for the permissions (licences, permits, rules etc) which will be used to control activities which could harm the environment.|
|Copper Anti-fouling Systems under Biocidal Products Directive:||
A new legal requirement came into force under the EU Biocidal Products Directive 98/8/EC, prohibiting the supply and use of copper as a biocide when used in liquid-cooling and processing systems.
Further details are available from the Anti-Fouling Systems page.
|DECC Environmental Alert (001/2014)- PON1 Reporting:||Issued by DECC (now BEIS) on 31 March 2014, this environmental alert (PDF document) highlights failures by a number of operators to comply with PON1 reporting requirements. Operators are reminded that in accordance with current reporting requirements PON1s must be reported within 6 hours to:
|Environmental Alert Notices||The Department of Business, Energy and Industrial Strategy (BEIS) regularly issues environmental alert notices in order to raise awareness of any environmental issues on the United Kingdom Continental Shelf (UKCS) so companies can respond appropriately. They are issued directly to Oil and Gas operators and published here.|
|Oil and Gas Authority (OGA) exploration strategy||The OGA has published an exploration strategy which outlines the key strategies which will be used to underpin maximum economic recovery of the UKCS.|
|Reporting Mud Components:||
Reporting of use and discharge must be undertaken on a component basis of the whole mud. Where a mud is recycled, BEIS has agreed that for reporting purposes, the assumption can be made that the recycled mud being used for a base is a mixture of the predominant base oil and barites and can be reported as such. Where additional additives are added to the recycled mud, these will need to be reported separately.
|Use and Discharge of Jacking Greases:||Use and discharge of jacking greases for jack-up rigs must now be included in each drilling operations application or well intervention operations application as appropriate.|
|Use and discharge of lead within UKCS:||In September 2014, DECC (now BEIS) issued a letter to all Operators / Owners of Installations and Mobile Drilling Units about the continued supply and use of lead by operators within UKCS, reminding them of their responsibility to ensure that Government commitments are adhered to in order to meet OSPAR objectives and the Directive on Environmental Quality Standards (2008/105/EC) requirements.|
