|Consent Needed:||ChemicalsA chemical permit is required under OCR. See Drilling Chemicals and Workovers.Oil ContaminationUnder OPPC, a permit is only required if well clean up fluids are likely to be contaminated with reservoir hydrocarbons.|
|How to Apply:||ChemicalsApplication must be made using a Drilling Operations application (wells and sidetracks), Well Intervention Operation application or Production Operation application.Oil ContaminationApplications for a permit under the OPPC Regulations must be made via the UK Oil Portal in the new PETS system. An Oil Discharge permit must be applied for as a Subsidiary Application Template (SAT) to the appropriate Master Application Template (MAT).Draft guidance notes on the new PETS system are available here (PDF document).
|Who to Apply to:||Chemical PermitChemical permit applications should be submitted on the UK Oil Portal.Oil Discharge PermitOil Discharge permit applications should be submitted on the UK Oil Portal.|
|When to Apply:||PETS Submit PETS applications at least 28 days before discharge starts.|
|Disposal of Well Clean Up Fluids:||
BEIS preferred option for disposal of SBM and OBM well clean up fluids is downhole reinjection (see letter from DECC (Word document)).
|Backloading of Oily Slops:||Operations giving rise to “oil contaminated fluids” include well clean-up, cementing, mud pit cleaning and operations where well bore fluids become contaminated with oil based mud, crude oil or condensate. In addition, fluids from rig floor drains and other tank cleaning operations can also be included.Backloading of slops must meet the requirements of MCA and HSE Guidance Notes:Good Practice for the Carriage of Oil Contaminated Cargoes for Transportation by Offshore Supply Vessel (PDF).Marine Guidance Note (MGN 283(M)) (PDF document)Dangerous Goods – Guidance on the Back Loading of Contaminated Bulk Liquids from Offshore Installations to Offshore Supply/Support Vessels.HSE Safety Notice Bulletin Number OSD 3-2010.|
|Definition of Oil:||The definition of oil has been updated under the OPPC Regulations and is defined as “oil means any liquid hydrocarbon or substitute liquid hydrocarbon, including dissolved or dispersed hydrocarbons or substitute hydrocarbons that are not normally found in the liquid phase at standard temperature and pressure, whether obtained from plants or animals, or mineral deposits, or by synthesis”. This definition is designed to capture all produced hydrocarbons, including condensate, and all uses of oil in the course of offshore exploration and production activities.However, the OPPC Regulations do not apply to hydrocarbons or substitute hydrocarbons that are designated as chemicals for the purpose of the Offshore Chemicals Regulations 2002.|
|Reservoir Hydrocarbons:||The concentration of dispersed oil in well clean-up fluids discharged to sea must not exceed 30 mg/l.The OPPC permit schedule will also specify permitted location and depth of discharge.|
|Minimisation of Contamination Levels:||All efforts should be made to utilise technologies and operational practices in order to minimise contamination levels.Oil & Gas UK have developed “Good Practice for Cleanup in Well Operations” (Word document) and a copy of this document can be found on the Oil & Gas UK website.|
|Reservoir Hydrocarbon Contamination:||The Oil Discharge permit schedule for well clean ups will detail the required sampling strategy (see OPPC Summary Sampling Requirements Table – Well Operations). Samples collected will be required to be analysed for dispersed oil content using current approved Beis methodology. In addition, the volume of well clean up fluids discharged must be measured or calculated to +/- 10% accuracy. The following information must be retained offshore for a period of 2 years:
BEIS (then DECC) Guidance on the Sampling and Analysis of Produced Water and Other Hydrocarbon Discharges is available from BEIS (Word document).
Persons undertaking sampling and analysis shall be provided with sufficient information, instruction and training to undertake the task. All training records must be retained.
|OBM/SBM Cleanups:||All chemical use/discharge must be recorded (see Drilling Chemicals).|
|What to Report – Sheens:||If at any time during the discharge a visible sheen is seen on the sea, the discharge should cease immediately and be reported to BEIS through the PON1 oil spill reporting mechanisms (see Oil Pollution Emergency Planning and Reporting). A report must be made as soon as sheen occurs.|
|Reservoir Hydrocarbon Contamination:||The following must be reported to BEIS following completion of the well clean-up operations:
Reports must be submitted to BEIS via the Inspectorate Data Mailbox at email@example.com
|OBM/SBM Cleanups:||One of the conditions of a chemical permit (PETS) is reporting. Reports need to cover:
As well as being used to check actual use and discharge of chemicals against that forecast, the information gathered is used to compile the OSPAR returns, which Contracting Parties are obliged to make.
Reports need to be made electronically on the EEMS website, on a quarterly basis. 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.
|Chemical Permits:||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, e.g. use/discharge of chemicals over the permitted quantities or use/discharge of chemicals not on the permit. Change in chemical type or increase in volume of use or discharge not provided for in the permit requires application for a variation to BEIS (done through revised drilling operation permit). BEIS recognises that in rare circumstances, unforeseen use of chemicals may be required at very short notice. Provision is made for oral approval for use from BEIS (in consultation with MS/CEFAS) (application must still demonstrate that a consideration of environmental impact has been made) followed by a written application via the drilling operation permit for record keeping. To avoid such situations, permit application should consider contingency chemicals.|
|Oil Discharge Permit:||Non-compliance would include discharge of well clean-up fluids without a valid permit being in place or at an oil in water concentration greater than 30 mg/l.Any non-compliance must be reported to BEIS using the OPPC non-compliance notification form, which can be downloaded from the BEIS website (Word document) along with appropriate Guidance Notes (word document).|
|Enforcement and Prohibition Notices:||BEIS, if of the opinion that the OPPC Regulations have been contravened, may issue an enforcement notice. This will specify the matters that constitute or are likely to constitute a contravention, steps required to rectify the matter and the time period within which these steps must be undertaken. 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 oil, 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.|
|Offences:||Offences under the OPPC Regulations, include (but are not limited to) the following:
A person found guilty of an offence will on summary conviction be liable to a fine not exceeding the statutory maximum.
|DECC Inspections:||The new OPPC Regulations give BEIS far greater and wider ranging powers to monitor and investigate all oil discharges whether lawful or unlawful. Inspectors may board an installation at any reasonable time and make such investigations as they consider necessary to investigate whether the requirements, restrictions or prohibitions imposed under the OPPC Regulations have been or are being complied with, or to monitor any discharge of oil. The BEIS (then DECC) Offshore Oil and Gas Environment Unit Enforcement Policy sets out the general principles that Inspectors shall follow in relation to enforcement, including prosecution.|
|Oil Discharge Permit:||If a Term Permit has been issued under the new OPPC Regulations (i.e. for an activity specific time limited discharge operation), this will only be valid for that operation and will expire after this time. A new application will be required for new planned discharge operations.|
|Chemicals including OBM/SBM/WBM:||See Drilling Chemicals.|
|None at present.|
|Deep Water Horizon:||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:
|Shipping cuttings/well clean-up fluids for offshore reinjection:||Drill cuttings and the first “flush” from well clean-ups can be shipped to another offshore site for reinjection. Supplementary advice from Derek Saward (BEIS) indicates that the first flush from the well can be transported as it is deemed to still be part of the drilling process. Subsequent flushes are a new operation and could not be transported.Note: This process must be as continuous as possible – any undue delay may be deemed by BEIS as a break in the process and would remove the possibility of shipment and reinjection.|
