This method statement covers a number of physical and biological indicators that could be used individually, or in combination, to help assess whether there is major or severe impact on river ecology due to altered flows arising from water resource activities.
UKTAG first published guidance on the classification of ecological potential in 2008. This guidance included lists of mitigation measures relevant to the range of adverse impacts on the water environment that the different water uses can have. For impoundments for the purposes of water storage and supply, 12 mitigation measures were identified. These recommendations supersede the existing guidance on assessing whether a measure is in place and adequate for 3 of these 12 mitigation measures, and have been determined following consultation and a stakeholder workshop throughout 2013.
The Final Recommendations on Environmental Standards following phase 3 of the review have been published (November 2013). This report includes zinc standards.
This is a Sniffer led project, the project funders were Scottish Environment Protection Agency, Environment Agency and Northern Ireland Environmental Agency, the work was done by APEM.
The environmental standards for river flows were developed from work undertaken by SNIFFER profect WFD48 . The environmental standards were developed in order to assess the risk to ecological status posed by alterations in flows across the flow regime.
A technical report on proposals for a first set of standards and conditions was published for review in 2006. The revised report was issued in August 2006 in the form of a recommendation to the UK governments. The UKTAG updated the report in November 2007.
This is a technical report that presents the first set of environmental standards and conditions proposed by the UKTAG to underpin the implementation of the Directive. Our report outlines the background to our proposals and describes the role they could play.
