    management, by which the Conference of the Parties requested the Open-ended Working Group to

    undertake a review of selected technical guidelines as appropriate and initiate updating as necessary,

    e.g., incineration on land (D10), specially engineered landfill (D5) and wastes collected from

    households (Y46).

    II. Implementation

    2. At its sixth session, in September 2007, by its decision OEWG-VI/4 the Open-ended Working

    Group, among other things, reiterated the invitation to countries and other stakeholders to provide

    comments regarding the review and updating of technical guidelines, in particular on incineration on

    land (D10), specially engineered landfill (D5) and wastes collected from households (Y46), and on their

    experiences implementing the existing technical guidelines on the environmentally sound management

    of hazardous wastes by 30 March 2008.

    3. As of 31 March 2008, the Secretariat had only received comments and proposals from Burkina 1Faso and the United Kingdom of Great Britain and Northern Ireland as set out in the annex to the

    present document.

    ? UNEP/CHW.9/1. 1 For reasons of economy, the comments are made available only in the languages in which they were submitted. They are presented as received and have not been edited by the Secretariat.

    Annex

    Comments from Burkina Faso on the review of technical guidelines

    Y46, D10 and D5

Ce message est d'abord vous informer que j'avais quelques suggestions relatives à la revision des

    directives techniques Y46, D10 et D5 respectivement en ce qui concerne la gestion des déchets

    ménagers, la co-incinération et la décharge contrôlée.

    Pour ce qui concerne la gestion des déchets (solides) ménagers, je pense qu'une attention particulière

    doit être accordée à la caractérisation et à la classification des déchets ménagers. Cette étape est

    nécessaire pour la destination finale des déchets ménagers. En effet cette étape fournirait les critères de

    choix parmi les options techniques d'élimination suivantes: le compostage, le co-compostage, la

    biométhanisation, le co incinération ou cogéneration, la décharge fossilisée. La décharge fossilisée est

    une technique qui consiste à enfouir en période sèche tous les déchets solides ménagers ou municipaux.

    Les déchets sont pris en "Sandwich" entres deux couches successives d'argiles et la dernière couche est

    constituée de terre végétale. Les avantages de cette technique sont entre autres l'absence de production

    de lixiviats, dimunition du coût d'exploitation, etc. L'inconvénient majeur est le manque de valorisation

    des déchets.

    Parmi les déchets ménagers ou domestiques, il est important de trouver des solutions pour la gestion des

    excréta qui constitue une problématique en Afrique Subsaharienne.

    En ce qui concerne le co-incinération, nous devons garder à l'esprit la synergie entre les conventions de

    Bâle et de Stockholm afin de réduire les risques d'augmentation des émissions de polluants organiques

    persistants notamment les dioxines et furannes. Du reste le co-incinération à l'avantage d'éliminer de

    grandes quantités de déchets. Mais le co-incinération avec récupération d'énergie est à promouvoir.

Comments from the United Kingdom of Great Britain and Northern

    Ireland on the proposal to the amend Basel Convention technical

    guidelines on specially engineered landfill (D5)

    The UK considers that the Basel guidance on specially engineered landfill is now quite out of date and would benefit from a significant overhaul. We suggest that it would be beneficial if the

    guidance included an indication of which hazardous wastes should or should not be landfilled, giving

    indications of preferred treatment routes and alternative disposal routes. The guidance also predates

    Directive 1991/31/EC on the landfill of waste and we consider it should be updated to include the

    Directive's requirements and technical standards for the design and operation of landfills as objectives,

    even if not as absolute requirements. The Environment Agency has issued the guidance notes listed

    below, which provide further details of these requirements and may be drawn on by Basel parties as

    appropriate in updating the guidelines:

    Landfill Sector Guidance note

    ? IPPC Landfill Sector Guidance Note S5.02

    http://publications.environment-agency.gov.uk/pdf/GEHO0407BMHO-e-e.pdf?lang=_e

    The Landfill Directive provides certain technical standards for landfill sites. Where the Landfill Directive does not provide the relevant technical requirements then the general principles of Directive

    96/61/EC on Integrated Pollution Prevention and Control are applied.

    The Sector Guidance Note for Landfill sets out recommendations for measures that are considered appropriate to meet the relevant technical requirements for landfills under Pollution

    Prevention Control.

    Landfill Technical Guidance

    ? TGN01: Hydrogeological Risk Assessment for landfill and the derivation of control and

    trigger levels

    UNEP/CHW.9/21

    This document provides guidance on the requirements for groundwater risk assessment of

    landfills and the setting of groundwater Control and Trigger levels. The guidance describes a tiered

    approach to hydrogeological risk assessment for landfill and sets out how Control and Trigger levels for

    groundwater (as required by the Landfill Directive) should be derived and used.

Comments of the United Kingdom on Basel Convention technical

    guidelines on incineration on land

     The UK considers that these guidelines are now quite old and would benefit from updating. More up to date and specific information is available on reception/handling, operational requirements, emission limits and monitoring, which could be used to expand on the options available to end users. The Basel guidelines also predate the European Community’s Directive on the incineration of waste (2000/76/EC), which has now been implemented and which defines the requirements for all hazardous and non-hazardous waste incinerators.

    There are several pieces of recent guidance that we suggest might be used in updating the Basel guidelines:

    (1) “Guidance for the incineration of waste and fuel manufactured from or including waste” issued

    by the UK Regulators. This is available at

    www.environment-agency.gov.uk/commondata/acrobat/incin_bat_guidance_1790458.pdf

    (2) More details of what constitutes BAT (Best Available Techniques) in the EC can be found in the BREF note issued by the European IPPC Bureau.

    (3) “Guidance on Directive 2000/76/EC on the Incineration of Waste” produced in the UK by Defra with the support of the Environment Agency. This is available at:

    www.defra.gov.uk/environment/ppc/envagency/pubs/incineration.htm

     More specifically, the initial sections of the report talk about municipal waste, although the focus of the guidance is hazardous waste. This is confusing and it would add clarity if the guidelines were restricted to the types of incineration they are intended to cover.

     In paragraph 7, the guidance does not mention bag filters which is the most commonly used technique where tight dust emission limits are imposed.

     Paragraphs 21-25 could be updated and improved using the guidance note mentioned at (1) above.

     Paragraph 31 is totally out of date. The document referred to as the proposal for the European Community Council of Ministers Directive on the Incineration of Hazardous Waste was adopted as Directive 94/67/EC in December 1994. This Directive was later repealed and its requirements were incorporated in the Waste Incineration Directive, 2000/76/EC, which was adopted in December 2000. The Directive imposes stringent controls on waste reception/handling, operational requirements, emission limits and monitoring and it would be helpful if its requirements could be mentioned in this guidance.
