Drill cuttings are delivered in skips or tanks (CTT and ISO). If the cuttings are slurrified, they can be transported in a bulk tank.
Drill cuttings with water-based drilling fluid are sent for suitable treatment.
If the cuttings contain milling swarf or cement, this must always be stated on the declaration form. Such waste is sent for different treatment.
Relevant information about the waste (e.g. origin, composition, analytical results, additives and pretreatment) must be included in the declaration.
Water-based drill cuttings may contain oil residues but must still be classified as water-based drill cuttings. Since many components of water-based drilling fluids are not environmentally hazardous, the reason for declaring the waste as hazardous must be stated. Incoming inspection will identify any milling swarf content.
The waste guide uses technical terms and codes to describe how different types of waste should be identified, classified, and handled. This makes it easier to find the correct waste fraction and comply with requirements for sorting, packaging, and delivery.
