Limit Values for Waste Accepted for Disposal in the Landfill Sites for Inert Waste or Parts of Landfill Sites Intended for Disposal of Inert Waste

[13 December 2016]

I. Leaching Test Limit Values

Leaching test limit values for waste to be disposed of in the landfill sites for inert waste or parts of landfill sites intended for disposal of inert waste shall be calculated by liquid (L) and solid substances (S) ratio (L/S, 2 l/kg and 10 l/kg total capacity) and directly expressed in mg/l ratio to C_o (in the first percolation test in eluate when L/S = 0.1).

No.	Ingredient	L/S = 2 l/kg	L/S = 10 l/kg	Co (percolation test)

17.	Dissolved organic carbon (DOC)**	240	500	160
18.	Total dissolved solids (TDS)***	2500	4000	-

Notes.

1. * If the waste fails to comply with these limit values for sulphate, it shall be considered as complying acceptance criteria if one of these limit values is not exceeded during the leaching test: 1500 mg/l as C₀ if L/S = 0.1 l/kg and 6000 mg/kg if L/S = 10 l/kg. The percolation test shall be used in order to determine the limit value if L/S = 0.1 l/kg in accordance with the initial balance conditions because the respective limit value is determined either by the leaching test of the set of samples or by the percolation test in accordance with the conditions which are close to the local balance.

2. ** If the pH value of waste fails to comply with the limit values of dissolved organic carbon (DOC), it may be also tested if L/S = 10 l/kg and pH is from 7.5 up to 8.0. It may be considered that waste conforms to the acceptance criteria of dissolved organic carbon (DOC) if the test result does not exceed 500 mg/kg.

3. *** The content of the total dissolved solids (TDS) may be used as an alternative for sulphate and chloride concentrations.

II. Limit Values for the Total Amount of Organic Parameters

No.	Ingredient	Limit value mg/kg
1.	Total organic carbon (TOC)	30000*
2.	Benzene, toluene, ethylbenzene, and xylene (BTEX)	6
3.	Polychlorinated biphenyl, including seven congeners (PCB)	1
4.	Hydrocarbon oil (C10-C40)	500
5.	Polycyclic aromatic hydrocarbons (PAH)	-

Note. * The board may allow a higher limit value in respect of soil if the dissolved organic carbon (DOC) achieves the limit value of 500 mg/kg, provided that L/S = 10 l/kg and pH is from 7.5 to 8.0 or the natural pH of the soil.

Limit Values for Waste Accepted for Disposal in the Landfill Sites for Hazardous Waste

I. Limit Values of Leaching Tests for Hazardous Waste

Leaching test limit values for hazardous granular waste to be disposed of in the landfill sites for hazardous waste shall be calculated by liquid (L) and solid substances (S) ratio (L/S, 2 l/kg and 10 l/kg total capacity) in the total release and directly expressed in mg/l ratio to C_o (in the first percolation test in eluate when L/S = 0.1 l/kg). All waste that is not monolithic shall be considered granular waste.

In order to extend the time for the achievement of the objectives for the reduction of the amount of waste disposed of in the landfill site for municipal waste, the plan shall include the following:

1) assessment of the previous, current, and projected municipal waste recycling, landfilling and other recovery and disposal rates, and also the streams from which the waste is composed;

2) assessment of the implementation of the national waste management plan and the national waste prevention programme;

3) reasons for which Latvia considers that it might not be able to achieve the respective objective for the achievement of the reduction of the amount of waste disposed of in the landfill sites for municipal waste and assessment of the time extension necessary to meet that objective;

4) the measures necessary for the achievement of the objectives for the reduction of the amount of waste disposed of in the landfill site for municipal waste and applicable during the extension period, including appropriate economic instruments and other measures taking into account the priority order of the waste management types laid down in the Waste Management Law;

5) a timetable for the implementation of the measures referred to in Paragraph 4 of this Annex, the competent authorities responsible for the implementation thereof and an assessment of their individual contribution to attaining the objectives applicable in the event of a time extension;

6) information on the funding for waste management in accordance with the polluter-pays principle;

7) measures to improve data quality which are required to improve planning and monitoring performance in waste management.
