A Somerset farmer has been ordered to pay out nearly £5000 after he admitted to causing pollution in a river in 2022.

Taunton magistrates heard that the Environment Agency went to the Fivehead River in June 2022 following report of pollution by a member of the public.

A water sample had significant discolouration and an unpleasant odour while monitoring equipment showed dissolved oxygen levels of below 12%.

An unpolluted watercourse would be expected to have oxygen levels above 70%.

The attending officers traced the source of the pollution to Underhill Farm, where they spoke to Mr Macey, 44, who said he had an issue with a silage clamp approximately four days earlier.

The clamp had been overfilled with grass and silage effluent had bypassed the front drainage and discharged into a piped ditch and then down to the Fivehead River.

He added that the reception tank for the silage clamp had been emptied a number of times to prevent further effluent reaching the river.

Analysis of the effluent showed it was approximately six times more polluting than untreated human sewage. Upstream of the farm no evidence of pollution was found.

During a voluntary interview under caution, Mr Macey declined to answer any questions put to him by agency officers but instead submitted a written statement.

He denied any pollution of sewage to the Fivehead River when officers were in fact investigating him for a silage effluent pollution.

Mr Macey later went on to state that a number of ‘other agencies’, that he would not identify, were the cause of any sewage discharge into the watercourse.

Environment Agency investigating officer, Kristian Steward said: “This case is an example of where a pollution incident could have been avoided and environmental harm prevented.

"For over 30 years regulations have required silage clamps to have perimeter drainage channels to allow any silage effluent to be properly collected, stored and safely spread to land.

“By overfilling the silage clamp the perimeter drainage system was ineffectual which, in this case, led to a discharge of highly polluting effluent to a watercourse.

"The issue was made worse by Mr Macey failing to contact the Environment Agency when first aware of the incident.

"If we had been informed immediately we could have given advice on techniques available for the storage of any excess silage as well as advising on how to minimise any impact on the environment.”

Mr Macey was fined £228. Magistrates also ordered him to pay costs of £4,502 and a victim surcharge of £90.
