Use of Chemicals – Consent Requirements


 

Under the Offshore Chemical Regulations 2002, all chemicals (including drilling muds) require a consent to discharge. Chemicals used must be registered with CEFAS and selected through a risk based approach. Different permit applications are in place for drilling (Drilling Operations Application), pipelines (Pipeline Operations Application), platforms (Production Operations Application), decommissioning and well abandonment (Decommissioning Operations Application), and workovers (Well Intervention Operations Application) Master Application Templates (MAT).

Identify chemical requirements and ensure all chemicals are registered with CEFAS (i.e. full HOCNF data set available).

Undertake risk assessment and CHARM modelling for chemicals not on OSPAR PLONOR list. Substitute any chemicals designated as high risk to the environment.
Prepare MAT. Environmental information is required for all applications, even if a MAT seeking an EIA directions or an ES has not been submitted.

Monitor and record use and discharge of all chemicals. Report quantities of chemicals used and discharged via EEMS.

Report any chemical spills to BEIS using PON1

Submission of annual substitution spreadsheets. Identifies all priority action or candidate substitution chemicals that were used and/or discharged throughout the year.
