The Provincial Executive of the southern Dutch province of Limburg will grant permission to Dutch cement factory ENCI to extract marl from the quarry near Sint Pietersberg until 2029, it was reported on September 9, 2004.  According to the Limburg provincial traffic affairs officer Mat Vestjens, the permit will step into power as soon as possible appeal proceedings against the plan are finalised.

According to the conditions of the permit, ENCI will be able to exploit the marl quarry in a depth of up to 55 metres beneath the Meuse river level. The permit will be valid for an area of 55 ha of the quarry. The remaining 150 ha, currently owned by ENCI, will have to be transferred to unnamed environment organisations under the terms of the permission.
