1 David Piper Task Manager (POPs enabling activities) UNEP DGEF POPs waste disposal under the Stockholm Convention Key elements

2 Convention provisions relating to wastes Article 3 measures to reduce/eliminate releases from intentional production and use Article 5 measures to reduce/eliminate releases from unintentional production Article 6 measures to reduce/eliminate releases from stockpiles and wastes

3 Article 3: Measures to reduce or eliminate releases from intentional production and use Restricts trade of POPs chemicals to: purposes/uses permitted under registered specific exemptions/acceptable purpose environmentally sound disposal –(paragraph 1d of Art 6)

4 Article 5 & Annex C: Measures to reduce or eliminate releases from unintentional production Develop action plans Promote –available, feasible and practical measures to achieve realistic and meaningful levels of release reduction or source elimination –substitute products and processes –the use of BAT/BEP BAT required for new Part II sources 4 years after entry into force Preventing POPs waste arising

5 Reducing releases “…promote available, feasible, practical measures…” Improved waste management Treatment of residuals and wastes Improved flue-gas cleaning Low-waste technologies Recovery and recycling of wastes Good housekeeping Improved product quality Avoiding use & generation of elemental Cl Less hazardous raw materials Process changes – e.g. closed systems Process modification – e.g. to improve combustion

6 Waste-related source categories Annex C Part II Waste incinerators, including co-incineration of municipal, hazardous or medical waste or of sewage sludge Cement kilns firing hazardous waste Secondary copper, aluminium and zinc production Annex C Part III –Open burning of waste, including burning of landfill sites –Crematoria and destruction of animal carcasses –Shredder plants for treatment of vehicles –Smouldering of copper cables –Waste oil refineries

7 Article 6: Measures to reduce or eliminate releases from stockpiles and wastes Stockpiles Wastes Contaminated sites Linkage to Basel Convention

8 Stockpiles Article 6 Paragraph 1 (a), (b), (c) Develop strategies to identify POPs stockpiles, & products in use Identify POPs stockpiles & products in use Manage POPs stockpiles in an environmentally sound manner

9 Wastes (& products and articles upon becoming wastes) Article 6 Paragraph 1 (a), (d) Develop strategies to identify POPs wastes Handle, collect, transport & store wastes in an environmentally sound manner Dispose –so that POPs content is destroyed or irreversibly transformed –In an environmentally sound manner if destruction not preferred –in a way that does not lead to recovery, recycling, reclamation, or reuse of POPs Transport POPs wastes across international boundaries according to international rules Article 6 Paragraph 1 (e); Contaminated sites Develop strategies to identify contaminated sites –(and ensure that remediation is performed in environmentally sound manner) Art 5 No identify here but implied in the next point

10 Does the waste Include products or articles consisting of, containing or contaminated with POPs? No Yes POPs waste Municipal, industrial or hazardous wastes Is the content of the waste arising known? Yes No Conduct analyses & report Yes No Dispose as appropriate for waste, noting obligations under Article 5 & Annex C re unintentional production of POPs byproducts 1.Prepare management plans to such that wastes are handled, collected, transported and stored in an environmentally sound manner 2. Dispose of wastes so that POPs content is destroyed or irreversibly transformed Or dispose in ESM where destruction is a)Not environmentally preferred, or b)POPs content is low (Article 6.1.a,d) Note obligations under Article 5 & Annex C Are wastes To be exported? Prepare management plans compatible with international rules, standards & guidelines Are sources of POPs wastes known? Identify sources of wastes & seek to minimize or eliminate, then … No Develop strategy, allowing waste separation & appropriate management compatible with Article 6.1.a,d, then… Are POPs wastes separated? No Yes Wastes consisting of, containing or contaminated with POPs Export of POPs waste for environmentally sound disposal ? Yes Prohibit unacceptable trade No

11 Paragraph 2 of Article 6 Stockholm COPs to cooperate closely with Basel COP to: –Establish levels of destruction and irreversible transformation to ensure that POPs characteristics are not exhibited –Determine what methods constitute environmentally sound disposal –Define “low POPs content” for purposes of environmentally sound disposal

12 Waste guidelines –Developed through Basel OEWG subgroup –Adopted by Basel Convention COP October 2004 Stockholm Convention Secretariat is requested: to prepare a report on such guidelines relating to POPs as may be adopted by the CoP to the Basel Convention, analyse the implications of those guidelines for the Stockholm Convention indicate elements that might be considered suitable for adoption under paragraph 2 of Article 6 of the Stockholm Convention.

13 PCBs – Annex A Part II Cease production of new PCBs immediately –New PCB = waste Eliminate use of in-place PCB equipment by 2025 Achieve environmentally sound disposal of PCB wastes as soon as possible and not later than 2028

14 PCB objectives Ensuring that PCBs in use remain in responsible hands Orderly removal from use –an integral part of business planning & capital investment –Government an important owner of PCBs Environmentally sound destruction Prevention of further contamination

15 Decision tree: PCBs PCBs Party possess ……..obsolete equipment contaminated with PCBs?..equipment contaminated with PCBs..PCB liquids and liquids contaminated with PCBs..other materials contaminated with PCBs Go to decision tree 11 (equipment and obsolete equipment contaminated with PCBs) 1. Manage these materials in accordance with paragraph 1 of Article 6 2. In lieu of note (ii) in Part I of Annex A, endeavour to identify other articles containing more than % PCBs (e.g. cable-sheaths, cured caulk and painted objects) 3. Provide a report every five years on progress in eliminating PCBs and submit it to the CoP Go to decision tree 5 (Stocks of POPs) 1. Classify as waste 2. Make determined efforts designed to lead to environmentally sound waste management of liquids contaminated with PCBs having a PCB content above 50 ppm as soon as possible but no later than Provide a report every five years on progress in eliminating PCBs and submit it to the CoP Go to decision tree 8 (wastes)

16 1. Define as waste 2. Make determined efforts designed to lead to environmentally sound waste management of equipment contaminated with PCBs having a PCB content above 50 ppm as soon as possible but no later than Provide a report every five years on progress in eliminating PCBs and submit it to the Conference of the Parties PCB Equipment and offline or decommissioned equipment contaminated with PCBs Go to decision tree 8 (wastes) Party possesses equipment contaminated with PCBs Does the Party use equipment contaminated with PCBs? Yes No Is the PCB-contaminated equipment de- commissioned? is the equipment maintained for reuse? No Go to decision tree 12 (use of PCB equipment) Party possess decommissioned or offline equipment contaminated with PCBs Except for maintenance and servicing operations, not allow recovery for the purpose of reuse in other equipment of liquids with PCBs content above % Note: Any PCB-containing equipment imported after becoming Party to the Convention has to be defined as waste

17 Use of equipment contaminated with PCBs Does equipment in use contain greater than 10 % PCBs and volumes greater than 5 litres? No Use of equipment contaminated with PCBs Go to decision tree 13 Make determined efforts to identify, label and remove from use by 2025, then…. Does equipment in use contain greater than 0.05 % PCBs and volumes greater than 5 litres? Does equipment in use contain greater than % PCBs and volumes greater than 0.05 litres? No Yes Does the analysis of equipment in use show a PCB content less than % ? Regarded as PCB-free under the SC Make determined efforts to identify, label and remove from use by 2025, then… Yes Endeavour to identify and remove from use by 2025, then… Yes No Yes No Reanalyze and reclassify PCB- containing equipment From decision tree 13 From decision tree 13 1st priority 2 nd priority 3rd priority Priorities related to volume and concentration of PCBs

18 Use of equipment contaminated with PCBs From decision tree 12 Provide a report every five years on progress in eliminating PCBs and submit it to the Conference of the Parties Is the equipment intact and non-leaking? No Take measure to improve condition of the equipment or decommission Yes Is the equipment used in areas where the risk from environmental release can be minimised and quickly remedied ? No Yes Is the equipment used in areas associated with the production or processing of food and feed ? Take measure to remove from use Yes Is the equipment used in populated areas, including schools and hospitals? No Yes Take all reasonable measures to protect from electrical failure which could result in a fire, and regular inspection of equipment for leaks No Go back to decision tree 12 to next lower priority and Take measure to reduce risk of environmental release and assure that releases can be quickly remedied Priorities related to risk posed by equipment

19 Extraction, pre- treatment technologies thermal desorption draining/ solvent washing Dismantling, shredding ‘ opening ’ + solvent wash other Transfer (drums/bulk) unserviceable equipment Decontaminated metals for recycling Soils, sediments, rubble etc. Decontaminated soil, rubble PCB oils contaminated wood, paper, clothing, cables etc Release monitoring POPs?  YES YES  No Air, liquid & solid waste treatment technologies Release to air, water, landfill Destruction technologies Incineration/ co-incineration Other oxidising process Chemical reduction process Other Release to hazardous waste site PCB equipment maintenance Unserviceable? Maintenance, refilling etc Release monitoring If ‘ extraction ’ and destruction on same site, transfer may be direct, otherwise drummed & shipped according to Basel requirements Servicing wastes contaminated mineral oils + solvents
