Section 2.3.1.
Environmental quality standards for surface waters and relative policy tasks


Article 2.3.1.1.

This Section provides for the partial transposition of Directive 2008/105/EC of the European Parliament and of the Council of 16 December 2008 on environmental quality standards in the field of water policy, amending and subsequently repealing Council Directives 82/176/EEC, 83/513/EEC, 84/156/EEC, 84/491/EEC and 86/280/EEC, and amending Directive 2000/60/EC, and for the partial transposition of Directive 2013/39/EU of the European Parliament and of the Council of 12 August 2013 amending Directives 2000/60/EC and 2008/105/EC as regards priority substances in the field of water policy.

The guide values stated in Appendix 2.3.1 shall be used as basic environmental quality standards for assessing the good ecological and good chemical status of surface waters. In the river basin management plans, the assessment of ecological status is divided into five classes, namely "very good", "good", "moderate", "unsatisfactory" and "poor".

In accordance with Article 60, paragraph 1, 1, a), 2), 3) and 4) of the Decree of 18 July 2003 concerning the integral water policy, the surface water bodies are divided into the following types in the river basin management plans [...]: "small stream", "small stream Kempen", "large stream", "large stream Kempen", "small river", "large river", "very large river", "fresh polder watercourse", "brackish polder watercourse", "fresh, mesotidal lowland estuary", "weakly brackish (oligohaline), macrotidal lowland estuary", "brackish, macrotidal lowland estuary", "salt, mesotidal lowland estuary", "circumneutral, heavily buffered lake", "moderately ion-rich, alkaline lake", "large, deep, eutrophic, alkaline lake", "large, deep, oligotrophic to mesotrophic, alkaline lake", "ion-rich, alkaline lake", "alkaline dune water", "very slightly brackish lake", "circumneutral, slightly buffered lake", "circumneutral, iron-rich lake", "heavily acidic lake", "moderately acidic lake" and "very brackish lake".


Article 2.3.1.2. The basic environmental quality standards stated in Article 2.3.1.1. also apply for the surface waters as stated in Sections 2.3.2., 2.3.3., 2.3.4. and 2.3.5., to the extent they supplement or raise special environmental quality standards applicable for these waters.

Article 2.3.1.3.

Derogations from the environmental quality standards may only be permitted in the river basin management plans in accordance with Articles 53, 54 and 56 of the Decree of 18 July 1993 concerning the integral water policy.

The basic environmental quality standards stated in Article 2.3.1.1, for the assessment of status, apply to the heavily modified and artificial bodies of water stated in Article 52 of the Decree of 18 July 2003 concerning the integral water policy. By way of derogation from this, other environmental quality standards may be determined for the following parameters in the river basin management plans: dissolved oxygen, electrical conductivity, chloride, sulphate, pH and all biological parameters.

In the case of the protected areas referred to in Article 71 of the same Decree, stricter environmental quality standards may be set in the river basin management plans.

The Government of Flanders shall, at the set times and at least when reviewing the river basin management plans, assess and where necessary adjust the environmental quality standards, as referred to in Article 2.2.3, 4 of the Decree of 5 April 1995 concerning the general provisions related to environmental policy.
