WFD once the Dangerous Substances Directive has been repealed. The five daughter<br />

directives to the Dangerous Substances Directive (listed in WFD Annex IX) will be reviewed.<br />

For those substances, which are found on the first WFD priority list, quality<br />

standards and emission limits will be updated. For those which are not on the first priority<br />

list, standards shall be reviewed with an option for entire repeal (Article 16(10)).<br />

Combined approach<br />

In general, under the Water Framework Directive, specific environmental quality standards<br />

(EQSs) for pollutants (i.e. concentrations <strong>of</strong> pollutants, not to be exceeded in the<br />

receiving waters) and more general ecological-status objectives must be met by applying<br />

controls on pollutant discharges. For certain activities and certain pollutants, a different<br />

form <strong>of</strong> combined approach applies whereby emission controls based on BAT,<br />

relevant emission limit values or, in the case <strong>of</strong> diffuse impacts, Best Environmental<br />

Practices must be applied first. If these are inadequate for meeting an environmental<br />

quality standard or objective, more stringent emission controls must be set accordingly.<br />

This true form <strong>of</strong> combined approach not only achieves the required environmental<br />

standards and objectives, but may even reduce inputs below these targets. The BAT<br />

and Best Environmental Practice requirements drive polluters to audit and improve their<br />

overall environmental efficiency. Such a combined approach applies to substances and<br />

processes controlled by the Nitrates Directive, the IPPC Directive, the Urban Waste<br />

Water Directive, directives adopted for priority substances and also the existing<br />

daughter directives to the Dangerous Substances Directive (Article 10). For priority substances<br />

(regulation at EU level), both environmental quality standards and uniform<br />

emission limit values should be set. However, Article 16(6) merely states that the<br />

Commission should "take account <strong>of</strong> Community-wide uniform emission limit values". It<br />

remains to be seen whether this is a binding requirement. In the absence <strong>of</strong> Community-wide<br />

measures on priority substances (i.e. if the Council and Parliament are unable<br />

to agree on measures), Member States have to act on these substances anyway. Article<br />

16(8) states that Member States have to establish environmental quality standards<br />

(EQS) and "controls on the principal sources <strong>of</strong> such discharges, based inter alia on<br />

consideration <strong>of</strong> all technical reduction options". This statement implies that Member<br />

States must apply the strong form <strong>of</strong> the combined approach, with application <strong>of</strong> Best<br />

Available Technologies first, and stronger controls if necessary. After all, this is the regime<br />

that applies in the event <strong>of</strong> Community-wide measures being agreed.<br />

Derogation and Extensions <strong>of</strong> Deadlines Regarding Chemicals<br />

Article 4(4) allows Member States to extend the deadline for achieving good status by<br />

up to twelve years beyond 2015. Such a rule is justified by the need to take account <strong>of</strong><br />

adverse natural conditions or insurmountable technical difficulties. However, there is<br />

also a more problematical clause allowing extensions on the grounds <strong>of</strong> disproportionate<br />

expense. Fortunately, the reasons and justification for making use <strong>of</strong> an extension<br />

<strong>of</strong> the deadline must be included in the River Basin Management Plan, for which public<br />

consultation is required at all stages. It should therefore be possible to ensure that extensions<br />

are only used when it can be shown that achievement <strong>of</strong> the objectives is impossible<br />

within the agreed timetable.
