In order to "improve the water quality in the northern region", the conditioning at the opencast mine residue holes (RL F, RL 12, RL A, RL 23, RL 14/15, RL Meuro) will be continued in order to achieve the discharge criteria by means of a ship-based or stationary water treatment plant. In order to control the conditioning results, monitoring services and scientific support of the seawater treatments are to be realized.

In order to "improve the water quality in the northern region", the conditioning at the opencast mining residues (RL F, RL12, RL A, RL 23, RL 14/15, RL Meuro) will be continued in order to achieve the discharge criteria of mid-ship-based or stationary water treatment plants.

In order to control the conditioning results, monitoring services and scientific support of the seawater treatments are to be realized.

Total main services over the period 2024 – 2027 in the opencast mine remnants (RL F, RL 12, RL A, RL 23, RL 14/15, RL Meuro):

- Approx. 700 depth profile measurements

- approx. 720 pieces of sampling

- approx. 1,200 pcs. Analysis of stagnation phase

- approx. 450 pcs. analysis of circulation phase

- approx. 800 pcs. Checking the water depth

- approx. 260 pcs. short reports
