Jääkreostusobjekti asukoht

The aim of the project is to eliminate residual pollution from the territory of the asphalt-concrete factory (ABT) at Ahtme mnt 88 and to carry out a study on the security of supply of the Ida-Viru County public water supply system.

  • Eliminating residual pollution from the territory of ABT at Ahtme mnt 88

The asphalt-concrete factory at Ahtme mnt 88 is a residual pollution site of national importance (code JRA0000078) entered in the Estonian Nature Information System, which is located on the cadastral unit of Asfaldi tn 12 in the Ahtme District of Kohtla-Järve.

ABT was established in the late 1960s. ABT had three asphalt mixing plants and used petroleum bitumen as a binder for asphalt production. Petroleum bitumen and shale oil were brought into the area by both rail and road.

Pollution surveys carried out by AS Maves in 2006 found soil contamination exceeding the industrial zone limits:

  • in the area between the boiler house and the asphalt mixing units;
  • in the area between the old boilers and the semi-subterranean petroleum bitumen storage;
  • north of the petroleum bitumen loading area. 

The soil is contaminated with volatile organic compounds (VOCs), 1-alkaline phenols, PAH components, and petroleum products. The contaminated soil layer lies at a depth of 0–3.5 m below the ground surface.

The contaminated soil has to be removed from the properties of Asfaldi tn 12 (ID 32206:002:0001), Asfaldi tn 10 (ID 32206:002:0015), Asfaldi street L2 (ID 32201:001:0503), Ahtme–Kohtla-Järve railway branch R5 (ID 32206:002:0002), and Ahtme mnt 86b 
(ID 32101:001:0155). The project foresees the remediation of the contaminated soil by an ex-situ method, i.e. excavation.

The work is planned to be carried out from 2024–2025.

  • Carrying out a study on the security of supply of the Ida-Viru County public water supply system

A study will be commissioned under the leadership of the EIC, providing an overview of the options for the introduction of alternative water resources, the activities required, and their costs. The study concerns the drinking water supply of around 100,000 people in Ida-Viru County.

The study is planned to be carried out from 2024–2025.

The project will be financed by the Just Transition Fund.
