Provision of integrated waste management services during geothermal drilling and well-testing

Provision of integrated waste management services for the full range of waste arisings during the drilling and testing of the first deep geothermal well at the Eden Project (approx. 150 days).

.

The majority of waste arisings will be non-hazardous drilling (extractive) wastes. There will be smaller quantities of other wastes: hazardous wastes (including oily or fuel-soaked rages, oil filters, engine oil and containers, hydraulic oil and containers); welfare wastes (general 'domestic' waste and recyclables); wood; metal; septic tank contents. Full details of anticipated waste arisings are given in the tender documents.

.

EGL requires a contractor to develop and provide integrated waste management services for the full range of waste arisings during the drilling and testing of the first deep geothermal well at the Eden Project. The successful contractor's obligations will include (but may not be limited to):

-- Provide a waste management procedure for each waste stream/waste category;

-- Design, provide, set up and manage an effective system for source separation, handling and storage of wastes;

-- Produce a waste management system that identifies whether the substances in the waste are (i) inert; (ii) ’hazardous substances’ or ’Persistent Organic Pollutants’ (POPs); (iii) non-hazardous (iv) mirror hazardous; or (v) mirror non-hazardous;

-- Identify an appropriate, cost effective approved waste disposal facility and ensure that all necessary permits and arrangements are in place to receive waste from the EGL site;

-- Have in place an appropriate spillage policy, produce an effective methodology to deal with spillage and produce a spill management plan that ensures that any material spilt on site will be contained and removed, minimising the potential for environmental harm;

-- Provide spill kits in all areas where extractive wastes are transferred or stored;

-- Provide mud pit emptying and cleaning and cuttings pit emptying and cleaning services;

-- Suggest cost-effective methods for the reuse of drilling waste and turning the drilling waste into value ;

-- Provide additional drilling solids removal and control equipment if required (e.g. centrifuges, dryers, etc.);

-- Propose effective rig site cleaning solutions;

-- Provide EGL with copies of all relevant paperwork, including: (i) a description and classification (inert, hazardous, or and the waste classification (EWC) code for all waste disposed off site; (ii) risk assessment for waste disposal; (iii) Waste Transfer Notes and/or Hazardous Waste Consignment notes; (iv) Waste Management Plan - setting out how wastes will be monitored, recorded and managed for disposal.

-- Maintain records of: (i) the quantities of all drill cuttings and their characterisation; (ii) all waste transfers. These records are to be retained by the operator for a minimum of 2 years and made available for inspection by the Environment Agency on request;

-- Provide continuous supervision of the waste management system throughout all operations within the drilling and testing programme;

-- Perform regular sampling and testing of drill cuttings and fluids waste streams using an accredited independent analysis company;

-- Use in-house or a third-party licensed transport companies to move waste to a pre-approved licensed waste disposal/treatment/recycling facility;

-- Provide all personnel and equipment (including pumps, jet washers, compressors, hoses, tanks, skips, and excavators) required for the onsite handling of all waste streams;

-- Have in place appropriate policies and procedures relating to the above;

-- Manage contact with, and report to, appropriate regulatory authorities in conjunction with all of the above. Additional information: This contract is part of a project part-funded by the European Union through the ERDF.
