Executive Summary

The second report by the Environmental Protection Agency (EPA) on the implementation of the Phosphorus Regulations. It is prepared under Article 4(4) of the Local Government (Water Pollution) Act, 1977 (Water Quality Standards for Phosphorus) Regulations, 1998 (S.I. 258 of 1998).

The report has been prepared from information and water quality data submitted by local authorities in their Implementation Reports and from water quality data collected by the EPA.The Phosphorus Regulations require that water quality be maintained or improved by reference to the baseline biological quality rating (rivers) or trophic status (lakes) assigned by the EPA in the 1995-97 review period or at the first occasion thereafter.

In the case of rivers, this Report analyses progress made in achieving the targets set in the Regulations, both nationally and at a local authority level, using current (i.e. 1998-2000 period) biological quality ratings (Q-ratings) and current median molybdate reactive phosphorus (MRP) levels, at river stations which have been assigned a baseline Q-rating. Similarly, in the case of lakes, this Report analyses progress made in achieving the targets set in the Regulations, both nationally and at a local authority level, using current trophic status measurements and current total phosphorus levels at lakes which have been assigned a baseline trophic status.

Water quality targets set in the Regulations must be met by 2007 at the latest for waters surveyed by the EPA in the 1995-97 period and within a maximum of ten years for waters first surveyed after 1997.

Under the Regulations, the local authorities were required to submit a Measures Report to the EPA by July 1999, setting out the measures to be taken to meet the prescribed standards. This was to be followed up by the submission of an Implementation Report to the EPA by July 2000 and every two years thereafter until 2008.

The EPA hosted a workshop in May 1999 to facilitate preparation of local authority Measures Reports. As a follow up to the workshop, we issued a Guidance Note to local authorities on preparation and submission of the Measures Report (EPA, 1999). We hosted a second workshop in June 2000 to facilitate preparation of local authority Implementation Reports. At this workshop, we issued a Guidance Note to local authorities on preparation and submission of the Implementation Reports (EPA, 2000a). Following the workshop, each local authority was supplied with a list of river stations and lakes in their functional area, which are to be maintained / improved under the Regulations. We also published a Synthesis Report of the Measures Reports (Clenaghan et al., 2000) to assist implementation of the Regulations.
