These Regulations amend certain provisions of the Nitrate Pollution Prevention Regulations 2008 (S.I. 2008/2349) (“the 2008 Regulations”) which relate to the measures required in the nitrate vulnerable zones in England. They also give statutory effect to the revised designations of nitrate vulnerable zones in England made by the Secretary of State on 10th April 2013. The 2008 Regulations implement in England Council Directive 91/676/EEC concerning the protection of waters against pollution caused by nitrates from agricultural sources (OJ No L375, 31.12.1991, p.1) (“the Nitrates Directive”). These Regulations also make a minor amendment to the Water Resources (Control of Pollution) (Silage, Slurry and Agricultural Fuel Oil) (England) Regulations 2010 (“the 2010 Regulations”). The 2010 Regulations make provisions in respect of the storage of slurry on farms throughout England and in that respect form part of the implementation in England of the Nitrates Directive.
