The use of sewage sludge on agricultural land is to be reviewed.
Farm minister Richard Lochhead has launched a formal review of the legislation and guidance for the spreading of sewage sludge on land.
The review, which will be carried out by the Government and Sepa, will take place over the next few months and involve stakeholders such as Scottish Water and local authorities.
“It has long been recognised that sewage sludge has the potential to improve soil quality and provide crop nutrients when used on agricultural land or in land restoration,” said Mr Lochhead.
“The Scottish Government has previously published guidance to ensure precautions are taken over the types of sewage sludge used to protect public health and soil quality, while generating significant benefits for the environment.
“However, over the last year a number of public complaints have been made. In light of that I have commissioned a review of legislation and guidance to determine what is and isn’t acceptable.”
Sewage sludge is produced by Scottish Water and contractors on a daily basis from sewage treatment works across Scotland.
NFU Scotland welcomed the review and said when applied and incorporated correctly, sewage sludge can be a valuable fertiliser and soil improver.
The union’s deputy director of policy, Andrew Bauer, said: “NFUS is aware of a number of instances where both the public and farmers have complained about the use of sewage sludge.
“We have discussed this issue with Sepa and Scottish Government previously and will be providing a submission to this consultation. It is in everyone’s interests that current concerns and issues are resolved and best practice around sewage sludge application is identified and followed.
“It is important that the protocols are accepted by all in the supply chain.”
