Objectives

  • To preserve the integrity of an aquatic, wetland or riparian environment
  • To avoid contaminating the forest

Additional information

Logging machines must not be washed at the top of a continuous slope leading directly to an open peat bog, a marsh, a swamp, a lake or a watercourse. Washing must take place further away, at a place where the land no longer slopes towards these environments. This will ensure that the water will be evacuated towards an area of vegetation, well away from the other environments.

Rules governing the washing of logging machines

Figure 38 Rules governing the washing of logging machines

Despite the first paragraph, washing water may be discharged in the forest provided that it is treated on the site and that it does not contain more than 30 mg/l of suspended matter and 15 mg/l of hydrocarbons (C10-C50).

Explanations

Water for washing logging machines may be discharged in the forest if all the conditions set out in subparagraphs 1 to 5 of the first paragraph of this section are met. However, if all the conditions cannot be met, but the washing water is treated on the site and does not contain more than 30 mg/l of suspended matter and 15 mg/l of hydrocarbons (C10-C50), it may still be discharged in the forest.

Residues from washing and water treatment on the site must be recovered and disposed of in accordance with applicable laws and regulations.
