Regional Fisheries Advisory Committee 4th March, 1985

This is the report from the Regional Fisheries Advisory Committee meeting, which was held on the 4th March, 1985. The report contains sections on Public Water Supplies in West Cumbria, proposals for water supply for British Nuclear Fuels Limited (BNFL), and the proposals for a fish pass at Ennerdale Weir. The section on BNFL looks at the proposal of British Nuclear Fuels Limited to take more water from Wastwater. This section includes information about Wastwater, Calder Valley Boreholes, Mine Water and the River Ehen, and other groundwater investigations. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

Also included is information on commercial salmon fishing in the River Lune and coarse fish close season in enclosed waters. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

Regional Fisheries Advisory Committee 2nd February, 1987

This is the report from the Regional Fisheries Advisory Committee meeting, which was held on the 2nd February, 1987. The report contains sections on fishing licence duties, the abolition of coarse fish close season in enclosed waters, commercial salmon fishing in the River Lune and proposed fish counter validation studies. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

Report on proposed improvements to Teignmouth Harbour

This is the Report on Proposed Improvements to Teignmouth Harbour from 15th March, 1971 prepared for the Teignmouth Harbour Commission. It reviews the Scheme III Breakwater along the lines recommended by the Hydraulics Research Station and the implications of deepening the berths at the Eastern Quay to a depth of thirteen feet below chart datum. The layout of the Hydraulics Research Scheme III Breakwater, as described in Para.16 of their Report No. EX489 dated April 1970, is shown on the accompanying Key Plan to a scale of 1:2500. It contains a subsoil survey and boreholes structure. It goes through the permissible draughts of ships and turning area, training wall, deepening of the eastern quay dredging and sewage dispersal.

Proposed Environmental Quality Standards for Nonylphenol in Water

This is the Proposed Environmental Quality Standards (EQS) for Nonylphenol in Water produced by the Environment Agency in 1997. The report reviews the properties and uses of Nonylphenol, its fate, behaviour and reported concentrations in the environment, and critically assesses available data on its toxicity and bioaccumulation. The information is used to derive EQSs for the protection of fresh and saltwater life as well as for water abstracted to potable supply.Nonylphenol (NP) is used extensively in the production of other substances such as non-ionic ethoxylate surfactants. It is through the incomplete anaerobic biodegradation of these surfactants that most nonylphenol reaches the aquatic environment in effluents, e.g. from sewage treatment works and certain manufacturing operations. It was explicitly stated by the Environment Agency that the EQS was to be derived for NP and not Nonylphenol ethoxylates. However, since NP is unlikely to be present in the aquatic environment in the absence of other nonylphenol ethoxylate (NPE) degradation by-products, the toxicity, fate and behaviour of some of these (i.e. nonylphenol mono- and diethoxylates (NP1EO and NP2EO), mono- and di-nonylphenoxy carboxylic acids (NP1EC and NP2EC) have also been considered in this report. In the aquatic environment and during sewage treatment, NPEs are rapidly degraded to NP under aerobic conditions. NP may then be either fully mineralised or may be adsorbed to sediments. Since NP cannot be biodegraded under anaerobic conditions it can accumulate in sediments to high concentrations.

Investigation of rising nitrate concentrations in groundwater in the Eden Valley, Cumbria: Phase 1 project scoping study

This is the Investigation of rising nitrate concentrations in groundwater in the Eden Valley, Cumbria report produced by the Environment Agency in 2003. This report focuses on groundwater nitrate concentrations in the Eden Valley. Most boreholes in the Eden Valley had nitrate concentrations less than 20 mg/l but a significant number had higher concentrations, some exceeding the EC maximum admissible concentration for drinking water of 50 mg/l. The main objectives of this report were to investigate the causes of rising nitrate concentrations in groundwater in the Permo-Triassic sandstone aquifers of the Eden Valley area and provide sufficient understanding of the groundwater and surface water flow system, including the sources of the nitrate contamination and the processes controlling nitrate movement, so that possible management options for reversing this trend can be considered.

Wetland resource evaluation and the NRA's role in its conservation. Classification of British wetlands

This is the Wetland resource evaluation and the NRA's role in its conservation: Classification of British wetlands report produced by the National Rivers Authority in 1995. This R&D document provides a clear classification for wetlands in England and Wales. The classification incorporates many of the existing ideas on the subject but avoids some of the problems associated with other classifications. A two-layered 'hydrotopographical' classification is proposed. The first layer identifies situation-types, i.e. the position the wetland occupies in the landscape, with special emphasis upon the principal sources of water. The second layer identifies hydrotopographical elements, i.e. units with distinctive water supply and, sometimes, distinctive topography in response to this. This system is seen as an independent, basic, classification upon which it is possible to superimpose additional, independent classifications based on other features (e.g. base-status, fertility, vegetation, management etc.). Some proposals for such additional classifications are provided.

Ashburn (Dart catchment) fisheries survey 1978

This is the Ashburn (Dart catchment) fisheries survey 1978 report produced by South West Water Authority in 1978. This report focuses on an exploratory survey to determine the population and distribution of all fish species and in particular salmonid species of the Ashburn stream. This survey is primarily intended for future reference on completion of the proposed Flood Alleviation Scheme of the Ashburn where it passes through the centre of Ashburton. Three sections were electro fished using D.C. Current Sections were chosen as easily accessible and through their relation in position to the intended scheme.
