SCHEDULE
CRITERIA AND PROCEDURES FOR THE ACCEPTANCE OF WASTE AT LANDFILLS
PART 1
GENERAL PRINCIPLES FOR THE ACCEPTANCE OF WASTE AT LANDFILLS
General principles for the acceptance of waste at all kinds of landfill
1.-(1) The following criteria shall apply to the acceptance of waste at any landfill.
(2) Waste may only be accepted at a landfill where its acceptance would not-
(a) result in unacceptable emissions to groundwater, surface water or the surrounding environment;
(b) jeopardise environmental protection systems (such as liners, leachate and gas collection and treatment systems) at the landfill;
(c) put at risk waste stabilisation processes (such as degradation or wash out) within the landfill; or
(d) endanger human health.
Additional general principles for the acceptance of waste at landfills for hazardous waste
2. Waste may only be accepted at a landfill for hazardous waste if-
(a) it is listed on the Hazardous Waste List of the European Waste Catalogue
( [6]) or has similar characteristics to those so listed; and
(b) its total content or leachability-
(i) does not present a short term occupational risk or an environmental risk; and
(ii) would not prevent the stabilisation of the landfill within its projected lifetime taking account of its after care period following closure.
Additional general principles for the acceptance of waste at landfills for non-hazardous waste
3. Waste may only be accepted at a landfill for non-hazardous waste if-
(a) it is listed on the Hazardous Waste List of the European Waste Catalogue or has similar characteristics to those so listed and-
(i) it is stable non-reactive hazardous waste;
(ii) its leaching behaviour is equivalent to that of non-hazardous waste which meets the relevant waste acceptance criteria; and
(iii) it is not deposited in cells used or intended to be used for the disposal of biodegradable non-hazardous waste; or
(b) it is any other waste listed on the European Waste Catalogue or has similar characteristics to those so listed.
PART 2
PROCEDURE FOR THE ACCEPTANCE OF WASTE AT LANDFILLS
Interpretation of Part 2
4. In this Part-
"installation" has the meaning given by regulation 2(1) of the 2000 Regulations;
(i) "waste regularly generated in the same process" shall mean individual and consistent wastes regularly generated in the same process, where-
(a) the installation and the process generating the waste are well known and the input materials to the process and the process itself are well defined;
(b) the operator of the installation provides all necessary information and informs the operator of the landfill of changes to the process (especially changes to the input material);
(c) the waste comes from a single installation or if from different installations, it can be identified as single stream with common characteristics within known boundaries (eg bottom ash from the incineration of municipal waste); and
(d) there is no significant change in the generation processes,
(aa) but shall not include wastes which do not require testing in accordance with paragraph 5(4)(a) or (c); and
(ii) "PAHs (Polycyclic Aromatic Hydrocarbons" means Naphthalene, Acenaphtylene, Acenaphthene, Anthracene, Benzo(a)anthracene, Benzo(b)fluoranthene, Benzo(k)fluoranthene, Benzo(g,h,i)perylene, Benzo(a)pyrene, Chrysene, Coronene, Dibenzo(a,h)anthracene, Fluorene, Fluoranthene, Indeno (1,2,3-c,d)pyrene, Phenanthrene and Pyrene.
Basic characterisation
5.-(1) Waste may only be accepted at a landfill if it is characterised by its producer, whom failing by any person responsible for its management, to ensure that all information necessary for safe disposal of the waste in the long term is available including at least the following information-
(a) the source and origin of the waste;
(b) the process producing the waste (including a description of the process and the characteristics of its raw materials and products);
(c) the waste treatment applied in compliance with regulation 12 of the 2003 Regulations, or a statement of reasons why such treatment is not considered necessary;
(d) the composition of the waste, including where relevant, an assessment of it against the relevant limit values in Part 3 and, where necessary and available, its other characteristic properties;
(e) the appearance of the waste (including its smell, colour, consistency and physical form);
(f) the code applicable to the waste under the European Waste Catalogue;
(g) in the case of hazardous waste, the relevant properties which render it hazardous according to Annex III of the Hazardous Waste Directive
( [7]);
(h) evidence demonstrating that the waste is not prohibited under regulation 9 of the 2003 Regulations;
(i) the landfill class at which the waste may be accepted;
(j) the likely behaviour (including, where relevant, leaching behaviour) of the waste in a landfill and any additional precautions that need to be taken at the landfill as a consequence; and
(k) whether the waste can be recycled or recovered.
(2) For waste regularly generated in the same process, the following additional information shall be provided-
(a) the compositional range for the individual wastes;
(b) the range and variability of characteristic properties;
(c) if appropriate, the leachability of the wastes determined by a batch leaching test, a percolation test or a pH dependence test;
(d) identification of the key variables to be tested for compliance testing, the frequency of compliance testing and options for simplification of compliance testing;
(e) in the case of waste which is produced in the same process in different installations, the scope of the evaluation which must include a sufficient number of measurements to show the range and variability of the characteristic properties of the waste.
(3) In order to characterise waste, it must be subject to prior tests in accordance with Part 4 of this Schedule to establish its composition and its leaching behaviour.
(4) Testing is not required in the case of any of the following types of waste-
(a) waste which may be accepted without testing under paragraphs 10 or 13 of Part 3 of this Schedule;
(b) waste in respect of which SEPA is satisfied that all the necessary information for the characterisation under sub-paragraph (1) can be provided without testing; or
(c) waste in respect of which SEPA is satisfied by way of a documented justification supplied to it that-
(i) the waste is of a type where testing is impractical or appropriate testing procedures and acceptance criteria are not available; and
(ii) the waste is of a type which is acceptable at the landfill class in question.
(5) Records of the information obtained for the purposes of characterisation under this paragraph shall be retained by the operator for at least two years after the date of characterisation.
Compliance testing
6.-(1) Waste regularly generated in the same process shall not require each batch to be tested as part of its basic characterisation but may instead be subject to compliance testing in accordance with this paragraph.
(2) Compliance testing shall consist of one or more of the tests applied in accordance with paragraph 5(3) above and shall include-
(a) testing of the key variables established under paragraph 5 so as to demonstrate that the waste meets the limit values for those variables;
(b) a batch leaching test using the same method as was used for the test undertaken under paragraph 5(3); and
(c) tests which demonstrate that the waste complies with the results of the characterisation carried out under paragraph 5 and the relevant acceptance criteria described in Parts 1 and 3 of this Schedule.
(3) Compliance testing shall be carried out at the times established in the characterisation but shall be no less frequent than once a year.
(4) Records of the compliance testing shall be retained by the operator for a period of not less than two years.
Wastes accepted without testing
7. Any type of waste which may be accepted without testing under paragraph 5(4) shall be subject to checking for compliance with its basic characterisation established under paragraph 5.
PART 3
WASTE ACCEPTANCE CRITERIA
Interpretation of Part 3
8. In this Part-
"granular waste" includes all wastes that are not monolithic;
"a mono-fill landfill" means a landfill which is authorised to accept only a single waste type;
"L/S = 10 1/kg" means a liquid to solid ratio of 10 litres to one kilogram; and
"stable, non-reactive hazardous waste" means hazardous waste, the leaching behaviour of which will not change adversely in the long-term, under landfill design conditions or foreseeable accidents-
(a) in the waste alone (for example, by biodegradation);
(b) under the impact of long-term ambient conditions (for example, water, air, temperature, mechanical constraints); or
(c) by the impact of other wastes (including waste products such as leachate and gas).
Criteria for landfills for inert waste
9. Waste may only be accepted at a landfill for inert waste if it meets either the requirements of paragraph 10 (wastes acceptable without testing at landfills for inert waste) or paragraph 11 (limit values for waste acceptable at landfills for inert waste).
Wastes acceptable without testing at landfills for inert waste
10.-(1) Subject to sub-paragraph (2), waste of the types set out in Table 1 may be accepted without testing at landfills for inert waste provided the waste is-
(a) from a single stream waste of a single waste type (unless different waste types from the list in Table 1 are accepted together); and
(b) is from a single source.
(2) Waste referred to in sub-paragraph (1) must be tested where there is suspicion of contamination or doubt that the waste meets the definition of inert waste in regulation 2 of the 2003 Regulations or the criteria in paragraph 11.
(3) If such testing reveals contamination or the presence of other materials or substances such as metals, asbestos, plastics or chemicals, the waste must not be accepted at a landfill for inert waste if the extent of the contamination is such as to increase the risk associated with the waste sufficiently to justify its disposal in other classes of landfill.

(a) This limit value for sulphate may be increased to 6,000 mg/kg, provided that the value of C0 (the first eluate of a percolation test at L/S = 0.1 l/kg) does not exceed 1,500 mg/l. It will be necessary to use a percolation test to determine the limit value at L/S = 0.1 l/kg under initial equilibrium conditions.
(b) If the waste does not meet this value for Dissolved Organic Carbon (DOC) at its own pH value, it may alternatively be tested at L/S = 10 l/kg and a pH between 7.5 and 8.0. The waste may be considered as complying with the acceptance criteria for DOC, if the result of this determination does not exceed 500 mg/kg.
(c) The value for Total Dissolved Solids can be used alternatively to the values for Sulphate and Chloride.
