F1Article 8aSpecific provisions for certain substances
1.
In the river basin management plans produced in accordance with Article 13 of Directive 2000/60/EC, without prejudice to the requirements of Section 1.4.3 of Annex V thereof regarding the presentation of the overall chemical status and the objectives and obligations laid down in point (a) of Article 4(1), in point (k) of Article 11(3) and in Article 16(6) of that Directive, Member States may provide additional maps that present the chemical status information for one or more of the following substances separately from the information for the rest of the substances identified in Part A of Annex I to this Directive:
(a)
substances numbered 5, 21, 28, 30, 35, 37, 43 and 44 (substances behaving like ubiquitous PBTs);
(b)
substances numbered 34 to 45 (newly identified substances);
(c)
substances numbered 2, 5, 15, 20, 22, 23 and 28 (substances for which revised, stricter EQS are established).
Member States may also present the extent of any deviation from the EQS value for the substances referred to in points (a) to (c) of the first subparagraph in the river basin management plans. Member States providing such additional maps shall seek to ensure their inter-comparability at river basin and Union level.
2.
Member States may monitor the substances numbered 5, 21, 28, 30, 35, 37, 43 and 44 in Part A of Annex I less intensively than is required for priority substances in accordance with Article 3(4) of this Directive and Annex V to Directive 2000/60/EC, provided that the monitoring is representative and a statistically robust baseline is available regarding the presence of those substances in the aquatic environment. As a guideline, in accordance with the second subparagraph of Article 3(6) of this Directive, monitoring should take place every three years, unless technical knowledge and expert judgment justify another interval.
