Pollution: Power Stations

Volume 475: debated on Thursday 15 May 2008

To ask the Secretary of State for Environment, Food and Rural Affairs what assessment his Department has made of the effects on (a) fish and (b) other marine creatures of thermal discharges from power plants to (i) rivers and (ii) coastal waters. (202082)

The Department obtains assessments of the potential effects of thermal discharges on fish and ecosystems at specific sites on an as-needs basis. These assessments are based on a variety of information, including knowledge of the thermal tolerances of fish and their ability to avoid unfavourable conditions, and the overall impacts on available habitat, much of which has been obtained from current and past research funded by DEFRA.
