To ask the Secretary of State for the Environment what research has been undertaken to establish any possible adverse environmental impact resulting from the discharge into the sea from the north Norfolk coast of glycol; what permissions exist in respect of such discharges; and if he will make a statement.
The National Rivers Authority and the former Anglian water authority have undertaken extensive monitoring of discharges of glycol and a survey of the receiving waters off the north Norfolk coast over the past two years. The results have shown that the discharges are having no detectable impact on the North sea.Details of discharge consents and information from routine monitoring of the discharges are held on the public registers maintained by the Anglian region of the National Rivers Authority, under the terms of the Water Act 1989.
