This document outlines the proposed measures for the Fifth Nitrates Action Programme. An interim review of the Fifth NAP was undertaken by the Nitrates Expert Group. The interim review identified that additional measures were required to achieve improvements in water quality. The Nitrates Expert Group made recommendations on the additional measures to both the Minister for Housing, Local Government and Heritage, and the Minister for Agriculture, Food and Marine. The Minister for Agriculture, Food and Marine sought feedback from the Department of Agriculture, Food and Marine Agriculture Water Quality Working Group on the proposed additional measure. The proposed additional measures are separated into two groups, those that require amendments to the Good Agricultural Practice (GAP) Regulations (S.I. 113 of 2022, as amended) and those measures that can be implemented without regulatory amendments.
