According to the Environment Agency, three Dorset farm businesses have paid a combined £33,500 after failures involving slurry storage and environmental permitting. Two cases involved slurry entering watercourses. In the third, new slurry stores were installed without the required permit. Rather than taking the cases to prosecution, the regulator accepted enforcement undertakings from Crockway Farms Ltd, Drummers Farming Limited and Crutchley Farms Partnership. The payments will now support environmental projects in Dorset, while each business has also introduced further compliance measures.
The announcement is a useful example of how the Environment Agency applies civil sanctions in the agricultural sector. An enforcement undertaking is a legally binding voluntary agreement offered by a business or individual when the regulator has reasonable grounds to suspect that an environmental offence has taken place. As set out in the government background note, enforcement undertakings for environmental offences were introduced under the Environmental Civil Sanctions (England) Order 2010 and the Environmental Civil Sanctions (Miscellaneous Amendments) (England) Regulations 2010. In practice, the route allows the regulator to secure corrective action and funding for environmental work without pursuing prosecution, while still requiring the operator to remedy the failure.
In the first case, the Environment Agency said Drummers Farming Limited, a farm near Sherbourne in Dorset, caused two slurry pollution incidents in spring 2024. In April, slurry from the farm's lagoon entered the Leigh Tributary of the Beer Hackett Stream, also known as the River Wriggle. The agency said alarms were activated, but the incident happened during the night and immediate action was not taken. In the second incident, laboratory analysis of water samples found ammonia at levels that could be lethal to aquatic life. The effect of the slurry was visible for more than 1.2 miles downstream. The business has since invested further in slurry storage, removed an overflow pipe and improved monitoring of slurry use. It also paid £10,000 to Dorset Wildlife Trust for the Winfrith and Tadnoll Wetland Restoration Project.
The second case concerned Crutchley Farms Partnership at Marsh Farm near Bridport. Environment Agency officers investigated pollution in the Mangerton Brook in October 2023 and traced the source to slurry entering the stream from a concrete tank's overflow pipe after a pump failed. The agency reported that the watercourse had an unpleasant odour and was covered in sewage fungus. Organic waste was identifiable for 300 metres downstream, with significant ecological deterioration over 800 metres. In response, the farm introduced a text warning system and daily inspections to reduce the risk of a repeat incident. The enforcement undertaking included a £7,500 payment to Dorset Wildlife Trust for a trees and wetland project.
The third case did not turn on a recorded pollution incident, but on permitting rules. The Environment Agency said Crockway Farms Ltd, an intensive pig farm, made major changes to the site by installing two new slurry stores without first obtaining an environmental permit. That requirement matters because intensive pig units are subject to a tighter permitting regime. The regulator must consider ammonia emissions as well as the risk of effluent discharges. The government notice states that ammonia in the atmosphere can be harmful to both human health and the environment. Crockway Farms Ltd paid £16,000 to the Farm and Wildlife Advisory Group South West, a Dorset conservation charity working on farm run-off and flood risk in catchments.
Taken together, the three cases show the Environment Agency using enforcement undertakings to address different forms of non-compliance within the same broad policy area. One set of breaches arose from pollution entering streams after failures in storage and response systems. Another arose from infrastructure being installed without the permit required before the work was carried out. For farm businesses, the practical lesson is straightforward. Slurry management is not limited to having storage on site. It also depends on alarm response, pump reliability, overflow control, regular inspection and, where operations change, checking whether a permit or permit variation is needed before construction begins.
The funding now moves to local environmental work in Dorset, with payments split between Dorset Wildlife Trust and the Farm and Wildlife Advisory Group South West. That gives the sanction a restorative element alongside the compliance action required from each operator. Senior Environment Officer David Womack said the rules on slurry exist to protect both people and the environment, and he urged farmers to contact the regulator early if they have concerns about storage or compliance. That is the clearest policy message in the case: early engagement is preferable to post-incident enforcement, but the regulator will still act where standards are not met.
