local environment agency plan BRUE AND AXE CONSULTATION REPORT JULY 1997 E n v ir o n m e n t Ag e n c y Ninonil Information Centre The Environment Agency Rio House Waterside Drive Aztec West BRISTOL BS1 2 +UD Due for return FOREWORD this Local Environment Agency Plan represents a significant step forward in environmental thinking. It has been clear for many years that the problems of land, air and water, particularly in the realm of pollution control, cannot be adequately addressed individually. They are interdependent, each affecting the others. The Government's answer was to create the Environment Agency with the umbrella responsibility for all three. The role and duties of the Agency are set out in this Consultation Report. This holistic approach is now reflected in this Plan. It is a logical development of the Catchment Management Plans prepared by the former National Rivers Authority, now subsumed into the new Agency. It sets out the environmental problems of the area in a way which has not been done before, and suggests the most important issues which should now be addressed. It is, I believe, vital reading for everyone concerned with the future of North Wessex. The catchment of the Rivers Brue and Axe encompasses a varied and complex environment, which includes a major part of the important Somerset Levels and Moors. The Plan covers all the work of the Environment Agency - water management, waste regulation and the control of heavy industrial processes. We look forward to hearing your views on the many environmental issues discussed here and I hope that with the help of our partners we can work towards a better environment in this area.
